Description

Technical Field

[0001] This utility model relates to the field of shift fork technology, and more specifically, to an adjustable shift fork structure for sorting machines. Background Technology

[0002] The adjustable fork structure of a sorting machine is a key component used in automated sorting systems such as logistics and warehousing. Its main function is to use the swinging or moving of mechanical forks to move items such as packages and boxes off the main conveyor line according to set rules, thereby achieving the sorting purpose.

[0003] However, traditional fork levers, which use rigid rods or rigid plates, have advantages such as high rigidity, simple structure, and low initial cost. However, because they are not adjustable, they have poor adaptability to working conditions. Furthermore, they cannot absorb impact energy at the moment the fork contacts and pushes the item. As a result, the instantaneous impact force generated by the hard contact will be concentrated on the surface of the item, such as the corners of the packaging and the edges of the box. Especially for fragile items such as glass products, packaging of precision instruments, or surface-sensitive items such as printed surfaces of cardboard boxes and shells of electronic products, this may cause indentations, cracks, or structural deformation, affecting the integrity of the item. The impact may also cause the item to undergo irregular displacement, such as flipping or bouncing, when it is pushed away, deviating from the preset sorting track, or even getting stuck in the gap between the fork and the conveyor line, requiring manual intervention and reducing sorting efficiency.

[0004] Therefore, an adjustable fork structure for sorting machines is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an adjustable fork structure for sorting machines. When sorting heavy goods, the tension bar is adjusted to enhance rigidity and ensure sufficient pushing force. When sorting fragile items, the tension bar is loosened to make the linear fork elastically buffered, reducing the impact force at the moment of contact and avoiding damage to the surface of the items.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] The sorting machine has an adjustable fork structure, including a toggle assembly. The lower end of the toggle assembly is provided with a fork adjustment assembly, and the lower end of the fork adjustment assembly is provided with multiple linear fork assemblies. Both ends of the toggle assembly are provided with support frames.

[0008] The actuating assembly includes a strip-shaped sliding plate, a lead screw is rotatably connected inside the strip-shaped sliding plate, a servo motor is fixedly connected to one end of the strip-shaped sliding plate, the output end of the servo motor is fixedly connected to one end of the lead screw, and a sliding block is installed in the middle of the lead screw through a screw sleeve, and the middle of the sliding block is slidably connected to the inside of the strip-shaped sliding plate.

[0009] Furthermore, the shift fork adjustment assembly includes a C-shaped connecting frame fixedly connected to the lower end of the sliding block. The lower end of the C-shaped connecting frame is fixedly connected to a drive housing. The upper end of the drive housing is fixedly connected to a hydraulic telescopic rod. The output end of the hydraulic telescopic rod, located inside the drive housing, is fixedly connected to a drive block. Inside the drive housing, a pair of mutually symmetrical adjustment blocks are slidably connected. The upper ends of both adjustment blocks are slidably connected to the drive block, and the lower ends of both adjustment blocks are fixedly connected to a Z-shaped tension adjustment rod.

[0010] Furthermore, the linear shift fork assembly includes multiple I-shaped hinge blocks and multiple straight hinge blocks, and the linear shift fork assembly is composed of multiple I-shaped hinge blocks and multiple straight hinge blocks that are interlocked with each other.

[0011] Furthermore, the interior of the strip-shaped sliding plate is provided with an H-shaped groove, and the overall shape of the sliding block is H-shaped, which matches the H-shaped groove inside the strip-shaped sliding plate.

[0012] Furthermore, a pair of symmetrical strip grooves are provided on the outer side of the strip sliding plate, and a plurality of threaded holes are provided at the upper end of the strip sliding plate. The strip sliding plate is bolted to a pair of support frames through the threaded holes at the upper end.

[0013] Furthermore, both ends of the driving block are inclined, and T-shaped protrusions are fixedly connected to both inclined surfaces of the driving block. The overall shape of the pair of adjusting blocks is triangular, and the upper end of the pair of adjusting blocks is provided with a T-shaped groove that slides and connects with the T-shaped protrusion. Strip-shaped sliding limiting protrusions are fixedly connected to both the front and rear ends of the pair of adjusting blocks.

[0014] Furthermore, the interior of the drive housing is provided with a pair of strip-shaped sliding grooves that are slidably connected to the strip-shaped sliding limiting protrusions.

[0015] In summary, this utility model has the following beneficial effects:

[0016] This solution uses a hydraulic telescopic rod in the shift fork adjustment assembly to push the drive block downwards, and the inclined structure drives the adjustment blocks on both sides to slide horizontally. Then, the tension of the linear shift fork assembly is changed by the Z-shaped tension adjustment rod. The linear shift fork assembly is composed of I-shaped and straight hinge blocks that are hinged alternately, similar to a flexible arm structure. When the Z-shaped tension adjustment rod changes the tension, the included angle between the hinge blocks can change dynamically, so that the shift fork as a whole presents a straight rigid or curved flexible shape, which can realize the switching between rigid shifting and flexible buffering.

[0017] When sorting heavy goods, adjust the tension lever to increase rigidity and ensure sufficient actuation force;

[0018] When sorting and handling fragile items, loosening the tension bar allows the linear fork to have elastic cushioning, reducing the impact force at the moment of contact and preventing damage to the surface of the items. Attached Figure Description

[0028] Reference Figures 1 to 6 As shown, the adjustable fork structure of the sorting machine in a preferred embodiment of the present invention includes a toggle assembly 1, a fork adjustment assembly 2 at the lower end of the toggle assembly 1, a plurality of linear fork assemblies 3 at the lower end of the fork adjustment assembly 2, and a support frame 4 at both ends of the toggle assembly 1.

[0029] The actuation assembly 1 includes a strip-shaped sliding plate 101, a lead screw 102 is rotatably connected inside the strip-shaped sliding plate 101, a servo motor 103 is fixedly connected to one end of the strip-shaped sliding plate 101, the output end of the servo motor 103 is fixedly connected to one end of the lead screw 102, and a sliding block 104 is installed in the middle of the lead screw 102 through a screw sleeve, and the middle of the sliding block 104 is slidably connected to the inside of the strip-shaped sliding plate 101.

[0030] The shift fork adjustment assembly 2 includes a C-shaped connecting frame 201 fixedly connected to the lower end of the sliding block 104. The lower end of the C-shaped connecting frame 201 is fixedly connected to a drive housing 202. The upper end of the drive housing 202 is fixedly connected to a hydraulic telescopic rod 203. The output end of the hydraulic telescopic rod 203, located inside the drive housing 202, is fixedly connected to a drive block 204. Inside the drive housing 202, a pair of symmetrical adjustment blocks 205 are slidably connected. The upper ends of both adjustment blocks 205 are slidably connected to the drive block 204. The lower ends of both adjustment blocks 205 are fixedly connected to a Z-shaped tension adjustment rod 206.

[0031] This solution uses a hydraulic telescopic rod 203 to push the drive block 204 downward. The inclined surfaces at both ends of the drive block 204 cooperate with the T-shaped groove of the adjustment block 205 through T-shaped protrusions, causing the adjustment block 205 to slide horizontally along the strip-shaped sliding groove of the drive housing 202. In turn, the tension of the linear shift fork assembly 3 is changed by the Z-shaped tension adjustment rod 206.

[0032] The linear shift fork assembly 3 includes multiple I-shaped hinge blocks 301 and multiple straight hinge blocks 302. The linear shift fork assembly 3 is composed of multiple I-shaped hinge blocks 301 and multiple straight hinge blocks 302 that are interlocked and hinged together.

[0033] The inside of the strip sliding plate 101 is provided with an H-shaped groove, and the overall shape of the sliding block 104 is H-shaped, and the overall shape of the sliding block 104 matches the H-shaped groove inside the strip sliding plate 101.

[0034] The outer side of the strip sliding plate 101 is provided with a pair of symmetrical strip grooves, and the upper end of the strip sliding plate 101 is provided with multiple threaded holes. The strip sliding plate 101 is bolted to a pair of support frames 4 through the threaded holes at the upper end.

[0035] Both ends of the drive block 204 are inclined, and T-shaped protrusions are fixedly connected to both inclined surfaces of the drive block 204. The overall shape of the pair of adjustment blocks 205 is triangular. The upper end of the pair of adjustment blocks 205 is provided with a T-shaped groove that slides with the T-shaped protrusion. Strip-shaped sliding limit protrusions are fixedly connected to both the front and rear ends of the pair of adjustment blocks 205.

[0036] The drive housing 202 has a pair of strip-shaped sliding grooves that are slidably connected to the strip-shaped sliding limit protrusions.

[0037] Specific implementation process: First, the support frame 4 fixes the strip sliding plate 101, providing stable support for the entire fork structure. The actuating component 1, the fork adjusting component 2, and the linear fork component 3 are connected in sequence to form an adjustable sorting execution unit. After the servo motor 103 starts, it drives the lead screw 102 to rotate. The screw sleeve in the middle of the lead screw 102 is connected to the sliding block 104. Since the sliding block 104 fits into the H-shaped groove inside the strip sliding plate 101, when the lead screw 102 rotates, the sliding block 104 can move horizontally in a straight line along the H-shaped groove of the strip sliding plate 101, thereby adjusting the horizontal position of the entire fork structure to adapt to different conveyor line widths or item positions. After the hydraulic telescopic rod 203 starts, its output end pushes the drive block 204 to move downward in the drive housing 202. The inclined surfaces and T-shaped protrusions at both ends of the drive block 204, along with the adjusting block... The T-shaped groove at the upper end of 205 slides in contact with the drive block 204. When the drive block 204 moves down, the two side adjustment blocks 205 slide horizontally along the strip-shaped sliding groove inside the drive housing 202. The Z-shaped tension adjustment rod 206 at the lower end of the adjustment block 205 moves with the adjustment block 205, thereby changing the tension of the linear shift fork assembly 3. The linear shift fork assembly 3 is formed by interlocking I-shaped hinge blocks 301 and straight hinge blocks 302, similar to a flexible arm structure. When the Z-shaped tension adjustment rod 206 adjusts the tension, the angle between the hinge blocks becomes smaller, and the linear shift fork assembly 3 has a straight rigid shape, which is suitable for sorting heavy goods and ensuring sufficient shifting force. When the Z-shaped tension adjustment rod 206 loosens the tension, the angle between the hinge blocks becomes larger, and the linear shift fork assembly 3 has a curved flexible shape, which has elastic buffer when contacting fragile items, reduces impact force, and avoids damage to the items.
