Description

Technical Field

[0001] This invention relates to the field of material handling technology, and more specifically to a device for destacking stacked empty crates. Background Technology

[0002] In existing material handling systems, some materials, due to their shape, size, and specifications, cannot be directly conveyed and must be placed in corresponding empty crates for transport. After the material is conveyed along with the empty crates, the crates need to be recycled. After recycling, they are reused for filling materials, and the recycled empty crates are stacked. Since each empty crate is used individually, the stacked crates need to be disassembled. Manual disassembly is not only inefficient but also fails to create any valuable output. Therefore, using mechanical equipment for crate disassembly will greatly improve work efficiency and save labor costs.

[0003] Current empty crate destacking technologies generally employ a combination of mechanical mechanisms and pneumatic or hydraulic systems. However, some empty crate destacking scenarios cannot utilize pneumatic or hydraulic methods. Furthermore, empty crate destacking equipment that does not use pneumatic or hydraulic systems is not only structurally complex and bulky, but also destacking only a small number of empty crates per stack. Conventional destacking equipment only has destacking functionality, or can only destacking stacked pallets. For overlapping empty crates, factors such as adhesion or jamming between crates can prevent the destacking process from being completed smoothly, which is more common with large stacks of empty crates.

[0004] Therefore, how to separate tightly stuck empty baskets is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a stacking empty basket destacking device that can provide sufficient separation force to separate the empty baskets even if they are stuck together.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stacking empty crate destacking device includes a destacking structure, which includes a destacking motor, a double-layer cam, a fork plate, a push plate, and a separation component mounted on the push plate.

[0008] The output end of the destacking motor is connected to a double-layer cam. The lower layer of the double-layer cam abuts against the fork plate, and the upper layer abuts against the push plate. The rotation of the double-layer cam causes the fork plate and the push plate to extend into the gap between the empty baskets. The separation component provides support in the gap between the baskets to separate the empty baskets.

[0009] Furthermore, the separation assembly includes a guide rod and an L-shaped plate; the L-shaped plate includes a first plate surface and a second plate surface placed at a certain angle;

[0010] One end of the guide rod is fixed to the push plate, and the other end is hinged to the first surface of the L-shaped plate; the angle between the first surface and the second surface is rotatably connected to the fork plate.

[0011] Furthermore, the separation assembly also includes a linear bearing fixed to the fork plate, through which the guide rod extends and retracts.

[0012] Furthermore, after the fork plate and the push plate penetrate into the gap between the baskets, the double-layer cam removes the pushing force on the push plate by rotating, and the guide rod pulls the L-shaped plate to make the end of the second plate rotate along the included angle to separate the empty basket.

[0013] Furthermore, it also includes a first elastic element, the two ends of which are respectively connected to the fork plate and the push plate. When the double-layer cam removes the thrust on the push plate by rotating, the first elastic element pulls the first plate surface by contracting.

[0014] Furthermore, it also includes a conveying component and a conveying lifting component; the conveying component is used to convey empty baskets or stacks of empty baskets.

[0015] The transmission component is connected to the transmission lifting component; the transmission lifting component lifts the transmission component to a preset height via a lifting motor to reach the working area of ​​the destacking structure.

[0016] Furthermore, it also includes a mounting frame for securing the destacking structure.

[0017] Furthermore, the mounting frame has an inlet side and an outlet side. The conveying assembly loads empty baskets and enters from the inlet side. After unpacking, the separated empty baskets are output from the outlet side.

[0018] A first detection device is installed on the entrance side of the mounting frame to detect whether the empty basket is too high.

[0019] A second detection device is installed on the outlet side of the mounting frame to detect whether there are empty stacks of baskets to be dismantled.

[0020] Furthermore, the transmission lifting assembly includes a lift and multiple height detection devices;

[0021] The elevator is installed at the bottom of the transmission component and is used to raise or lower the height of the transmission component; the multiple height detection devices are fixed at different heights and are used to detect the height of the transmission component.

[0022] Furthermore, a position detection device is installed in the unstacking area of ​​the empty crate stack on the transmission component, and the position detection device is used to detect the stopping position of the empty crate stack.

[0023] Furthermore, a fixed shaft is provided on the surface of the fork plate, and a bearing is sleeved on the fixed shaft. The bearing contacts the cam; when the cam rotates, the bearing rotates synchronously and pushes the bearing through the outer edge of the cam, so that the bearing pushes the fork plate under the action of the fixed shaft. Similarly, the surface of the push plate also contacts the previous cam of the cam through the fixed shaft and the bearing, and is advanced by the rotation of the cam.

[0024] Furthermore, a detection device is installed on the inner column of the mounting frame to detect the position of the transmission component. Changing the position of the detection device changes the number of empty baskets disassembled.

[0025] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a stacking empty crate destacking device. While fulfilling the normal empty crate or pallet destacking function, considering factors such as possible sticking or jamming between empty crates, a double-layer cam structure is adopted to complete the destacking and separation of empty crates in one action. This satisfies the automatic destacking of empty crates in multiple application scenarios. It not only has a simple structure and small size, but also destacking a large number of empty crates per stack, improving the processing efficiency of empty crate destacking. Furthermore, the collision noise of empty crates is minimal throughout the destacking process, effectively reducing the operating noise of the empty crate destacking equipment.

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figures 1-5 This invention discloses a stacking empty basket destacking device, including a destacking structure 2. The destacking structure 2 includes a destacking motor 202, a double-layer cam 205, a fork plate 207, a push plate 203, and a separation component 204 mounted on the push plate 203. The output end of the destacking motor 202 is connected to the double-layer cam 205. The lower layer of the double-layer cam 205 abuts against the fork plate 207, and the upper layer abuts against the push plate 203. The double-layer cam 205 rotates to cause the fork plate 207 and the push plate 203 to extend into the gap between the empty baskets in the stack of empty baskets 5. The separation component 204 provides support in the gap between the baskets to separate the empty baskets.

[0035] There can be two destacking structures 2, which are arranged opposite to each other. The two oppositely arranged destacking structures 2 perform the task of destacking the empty basket stack 5 located between them: the double-layer cams 205 on both sides extend into the gap between the frames through the two layers of structures, and the upper and lower layers respectively abut against the upper and lower empty baskets. Even if the empty baskets 6 are stuck together, they can provide sufficient separation force to separate them.

[0036] To further implement the above technical solution, the separation component 204 includes a guide rod and an L-shaped plate; the L-shaped plate includes a first plate surface and a second plate surface placed at a certain angle; one end of the guide rod is fixed to the push plate 203, and the other end is hinged to the first plate surface of the L-shaped plate; the angle between the first plate surface and the second plate surface is rotatably connected to the fork plate 207; wherein, a guide rod 209 is fixed on each of the left and right sides of the push plate 203, and the rod part of the guide rod 209 passes through a linear bearing to limit its smooth linear extension and retraction movement.

[0037] During the destacking process, the double-layer cam 205 rotates to the side away from the axle, causing the upper cam to push the pusher plate 203 and the lower cam to push the fork plate 207, placing the ends of the fork plate 207 and the separation components 204 on the pusher plate at the gaps between the empty baskets in the stack 5. The separation components 204 on both sides of the stack 5 actuate, causing the second surface of the L-shaped plate to rotate upwards along the included angle from its state of being attached to the upper surface of the fork plate 207. The end of the second surface exerts an upward force on the upper empty basket 6, while the fork plate 207 simultaneously restricts the lower empty basket from moving upwards due to adhesion, thus separating the upper and lower empty baskets.

[0038] When the separating assembly 204 operates, as the double-layer cam 205 rotates, the outer edge of the upper cam gradually approaches the axle, reducing the thrust of the upper cam on the push plate 203. Simultaneously, the separating assembly 204 can retract via the reset assembly, causing the second plate surface to gradually move away from the upper surface of the fork plate 207. The reset assembly is a first elastic element, with its two ends connected to the fork plate 207 and the push plate 203, respectively. When the double-layer cam 205 removes the thrust on the push plate 203 by rotating, the first elastic element retracts and pulls the first plate surface.

[0039] To further implement the above technical solution, the separated empty crates 6 can be automatically output to downstream equipment. Therefore, it also includes a transmission component 101 and a transmission lifting component 102; the transmission component 101 is used to transmit the empty crates 6 or the stack of empty crates 5; the transmission component 101 is connected to the transmission lifting component 102; the transmission lifting component 102 lifts the transmission component 101 to a preset height to reach the working area of ​​the destacking structure 2 through a lifting motor.

[0040] The conveying and lifting assembly 102 includes a lift and multiple height detection devices 3. The lift is installed at the bottom of the conveying assembly 101 and is used to raise or lower the height of the conveying assembly 101. The multiple height detection devices 3 are fixed at different heights and are used to detect the height of the conveying assembly. A position detection device is installed at the unstacking work area of ​​the empty crate stack 5 on the conveying assembly 101. The position detection device is used to detect the stopping position of the empty crate stack.

[0041] To further implement the above technical solution, a mounting frame 1 is also included. The mounting frame 1 can be fixed in place and can provide fixed position points for other structures.

[0042] Specifically, the mounting frame 1 can be used to fix the destacking structure 2. Both sides of the mounting frame 1 are fixed with motor mounting bases 201 by bolts to fix the destacking motor 202. The output end of the destacking motor 202 is provided with a mounting base plate 206, which is fixed to the mounting frame 1. A fork plate 207 and a push plate 203 are installed on the top of the mounting base plate 206 in sequence. A guide rail is installed on the upper surface of the mounting base plate 206, and the fork plate 207 and the mounting base plate 206 are connected by the guide rail. A second elastic space is also connected between the fork plate 207 and the mounting base plate 206 to reset the fork plate 207 in the pushed-out state.

[0043] The mounting frame 1 has an inlet side and an outlet side. The transmission assembly 101 loads empty basket stacks 5 and enters from the inlet side. After unpacking, the separated empty baskets are output from the outlet side. The mounting frame 1 is equipped with a detection device 4. Specifically, a first detection device 401 is installed on the top of the inlet side of the mounting frame 1 to detect whether the empty basket stacks are too high. A second detection device 402 is installed on the outlet side of the mounting frame to detect whether there are empty basket stacks to be unpacked. The first detection device 401 and the second detection device 402 are both photoelectric detection devices.

[0044] The transmission surface of the transmission component 101 passes through both sides of the entrance and exit of the mounting frame 1; a vertical plate is fixed inside the mounting frame 1, and a height detection device 3 is fixed on the plate from bottom to top. The upright plate is fixed from bottom to top with a first height detection device 301, a second height detection device 302, a third height detection device 303, and a fourth height detection device 304. The first height detection device 301 is set at the initial height of the transmission component 101; the second height detection device 302 is set at the height at which the transmission component 101 outputs separated empty baskets; the third height detection device 303 is set at the height at which the stack of empty baskets 5 is placed in the working position. This height can be selected according to the actual situation. The height of the third height detection device 303 is set according to the number of baskets to be destabilized in a single operation, so that when the transmission component 101 stops at the third height detection device 303, the position of the stack of empty baskets 5 on the transmission component 101 being destabilized is consistent with the number required for the destabilization task; the fourth height detection device 304 is set at the height of the next empty basket in the destabilization structure 2. When the transmission component 101 is raised to the height of the fourth height detection device 304, the bottom of the separated stack of empty baskets is close to the transmission component 101.

[0045] The workflow of this invention is as follows:

[0046] S1: The transmission component 101 operates, conveying the empty crate stack 5 into the installation frame. The specific stacked empty crate stack 5 is conveyed to the entrance side of the installation frame 1 by the transmission component 101. The first detection device 401 detects whether it exceeds the height limit. If it does, the transmission stops. The empty crates that do not exceed the height limit are continued to be conveyed downwards and enter the installation frame 1. The front end of the empty crate stack 5 triggers the position detection device. After receiving the stop signal from the position detection device, the transmission component 101 stops. At this time, the empty crate stack 5 stops between the two destacking structures. The transmission component 101 is at the initial height. When there is an empty crate stack 5, the second detection device 402 detects the empty crate stack 5 signal.

[0047] S2: The transmission lifting component 102 is running. The second detection device 402 transmits the empty basket stack 5 signal to the transmission lifting component 102. At this time, the transmission component 101 is in the initial state at the first height detection device 301. As the transmission lifting component 102 runs, the transmission component 101 is lifted to the position of the third height detection device 303, so that the empty basket stack 5 is placed at the destacking working height.

[0048] The transmission and lifting assembly 102 includes a lifting motor, a drive wheel, a synchronous pulley, a driven synchronous pulley, a synchronous belt, a lifting mounting assembly, and a guide rail slider assembly. The lifting motor is mounted on the mounting frame 1 to provide lifting power. The drive wheel is connected to the motor via a shaft, transmitting the power provided by the motor to the synchronous pulley via the synchronous belt. The synchronous pulleys are symmetrically mounted on the lower part of the mounting frame and are connected by shafts to transmit power to the driven synchronous pulley via the synchronous belt. The driven synchronous pulleys are symmetrically mounted on the upper part of the mounting frame and are connected by shafts to achieve synchronization. The lifting mounting assembly is mounted on the transmission assembly 101 and the synchronous belt, serving as a connection to enable the transmission assembly 101 to move up and down. The guide rail slider assembly is mounted in the middle of the mounting frame 1 to provide the running trajectory.

[0049] S3: The destacking structure 2 is running. The third height detection device 303 transmits a signal to the destacking structure 2. After receiving the signal, the destacking structure 2 performs destacking and maintains the destacking state.

[0050] S4: The transmission component 101 operates, transporting the empty crates 6 downstream. Specifically, after the destacking structure 2 operates, the transmission lifting component 102 drives the transmission component 101 and the disassembled empty crates to the position of the second height detection device 302. The second height detection device 302 transmits a signal to the transmission component 101, and the transmission component 101 starts operating to transport the disassembled empty crates to the downstream equipment. At this time, the photoelectric detection device on the transmission component 101 detects no empty crate signal, and the second detection device 402 detects a crate signal, indicating that there are empty crates to be disassembled.

[0051] S5: The transmission lifting component 102 operates, lifting the transmission component 101 to a position close to the fourth height detection device 304. The fourth height detection device 304 transmits a signal to the destacking structure 2. After receiving the signal, the destacking structure 2 resets and places the empty basket stack 5 on the transmission component 101. The transmission lifting component 102 operates, lifting the transmission component 101 to a position close to the third height detection device 303.

[0052] S6: Repeat S3-S5 until the second detection device 402 and the detection device on the hand of the transmission component 101 detect the no-frame signal, and the transmission lifting component 102 drives the transmission component 101 to return to the initial state at the first height detection device 301.

[0053] In S3, the disassembly process is as follows:

[0054] When the destacking structure 2 receives the destacking signal, the destacking motor 202 starts and drives the double-layer cam 205 and the cam detection device 208 to rotate. As the double-layer cam 205 rotates, it pushes the fork plate 207 and the push plate 203 to move forward. When the double-layer cam 205 rotates 145 degrees, the fork plate 207 reaches the destacking position and remains in this state between 145 and 215 degrees. When the double-layer cam 205 rotates 155 degrees, the upper double-layer cam pushes the push plate 203, which drives the guide rod 209 to move forward. The forward movement of the guide rod 209 drives the separation component 204 to convert linear motion into rotational motion to perform empty basket separation. When the double-layer cam 205 rotates 180 degrees, the separation component 204 reaches the separation position. At this time, the cam detection device 208 also rotates 180 degrees, and the entire destacking structure 2 is in the destacking and separation state.

[0055] When the destacking structure 2 receives a reset signal, the destacking motor 202 starts and drives the double-layer cam 205 and the cam detection device 208 to rotate. At the same time as the double-layer cam 205 rotates, the fork plate 207 moves backward under the tension of the reset spring 210. When the double-layer cam 205 rotates 325 degrees, the fork plate 207 returns to the reset position and remains in this state between 325 and 360 degrees. The double-layer cam 205 continues to rotate, and the push plate 203 is driven by the tension of the reset spring 210 to push the guide rod 209 to move backward, thereby driving the separation component 204 to reset. When the double-layer cam 205 rotates 205 degrees, the separation component 204 returns to the reset position and remains in this state between 325 and 360 degrees. When the double-layer cam 205 rotates 360 degrees in one revolution, the cam detection device 208 also rotates 360 degrees, and the entire destacking structure 2 is in the initial reset state.
