[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] like Figure 1-8 As shown in some illustrative embodiments, a linen tipping and transport device is provided, including: a linen tipper 100 and a linen-slipping platform 200.

[0030] The linen tipper 100 is used to lift and tip the linen cart 300 loaded with washed linens, causing the linens to be dumped from the cart onto the linen dumping platform 200. The linen dumping platform 200 is located behind the linen tipper 100, in the direction of linen transport, and is used to receive the linens dumped from the linen cart 300 and transport them to the spreading machine or feeder.

[0031] Workflow:

[0032] Preparation of linen cart: Push the linen cart 300 loaded with cleaned linens onto the forks 110 of the linen tipper 100, so that the bottom fixing ring 310 of the linen cart is engaged with the forks 110.

[0033] Lifting and Tilting: The linen tipper 100 is started and fixed to the bottom fixing ring 310 of the linen cart by the forks 110. Then it is lifted to a certain height and then tilted to a certain angle, so that the linens in the linen cart 300 are tilted onto the linen dumping platform 200.

[0034] Linen conveying: The dumping platform 200 starts up and smoothly conveys the dumped linens to the spreading machine or feeding machine. The spreading machine or feeding machine sorts and distributes the linens, completing the subsequent processing of the linens.

[0035] The linen tipping machine 100 can quickly unload linens from the cart onto the linen loading platform 200, significantly improving linen transfer efficiency compared to traditional manual operation. The automated tipping and conveying process reduces the need for manual handling, lowers worker workload, and increases efficiency. When used in conjunction with the linen loading platform 200, the tipping machine 100, by controlling the tipping angle and conveying speed, reduces the workload of linen loading and ironing workers, further increasing production efficiency. It also reduces linen falling during transport, effectively preventing secondary contamination.

[0036] The linen tipper 100 includes: forks 110, track support 120, lower support 130, and a power unit 140 for driving the lower support 130 to move up and down.

[0037] The forks 110, used for loading and securing the linen cart 300, are made of robust materials to ensure the stability of the entire structure. The main function of the track support 120 is to support the forks 110 and provide movement guidance, ensuring the forks 110 move along a predetermined trajectory for smooth lifting and tilting. The lower support 130 connects to the forks 110 and is the direct target of the power unit 140. The power unit 140 acts as a power source, driving the lower support 130 to move up and down, thereby achieving the lifting and tilting of the linen cart 110.

[0038] The working principle of the linen tipper 100 is as follows: The linen cart 300 is pushed onto the forks 110 and secured; the power unit 140 starts, driving the lower support 130 upward through the transmission system, simultaneously raising the forks 110; when the forks 110 reach a certain height, the lower support 130 continues to rise, causing the forks 110 to flip to a certain angle, and the linens inside the linen cart 300 are tipped onto the linen-tipping platform 200; after the linens are tipped, the power unit 140 reverses its operation, returning the lower support 130 and forks 110 to their original positions, ready for the next operation. Through this structural design, the linen tipper 100 can efficiently and safely complete the tipping operation of the linen cart, improving the automation level and production efficiency of the linen washing industry.

[0039] The track support 120 consists of a vertical track 121 and an arc track 122, and both the vertical track 121 and the arc track 122 are groove-shaped tracks.

[0040] The vertical rail 121 is installed vertically, providing a path for the lower bracket 130 to move vertically. Track wheels are provided on both sides of the lower bracket 130, and the track wheels roll inside the grooved vertical rail 121 to realize the up and down movement of the lower bracket 130.

[0041] An arc-shaped rail 122 is located at the top of the vertical rail 121 and extends backward toward the rail bracket 120 to change the direction of movement of the forks 110, enabling them to complete the flipping action. During installation, the arc-shaped rail 122 must be smoothly connected to the vertical rail 121 to ensure the continuity and stability of the forks 110 during movement. The forks 110 are equipped with rail wheels 150 and lugs 160. The lugs 160 are hinged to the top of the lower bracket 130, and the rail wheels 150 can roll along the grooved arc-shaped rail 122.

[0042] Working principle:

[0043] When the power unit 140 is started, it drives the lower support 130 to rise along the vertical track 121 via the transmission system, simultaneously raising the forks 110. After the lower support 130 rises to a certain height, it continues to move. At this time, the track wheel 150 transitions from the vertical track 121 to the arc track 122. Under the action of the arc track 122, the forks 110 rotate around the hinge point between the lug 160 and the lower support 130, realizing the tipping of the linens. After the linens are tipped, the power unit 140 reverses its operation, and the lower support 130 moves down along the vertical track 121 and descends to its initial position.

[0044] The advantages of this design are: both the vertical rail 121 and the arc rail 122 are grooved, which enables precise lifting and tilting of the linen cart, and ensures the stability and safety of the forks 110 during the tilting process; it is simple to manufacture and has low manufacturing cost, protecting the linens and equipment; it improves the automation level of linen tilting and reduces the labor intensity of operators; the equipment has a compact structure, is easy to operate, and is convenient to maintain.

[0045] The track wheel 150 includes: track wheel support 151, bearing 152, shaft 153 and wheel body 154.

[0046] The track wheel support 151 is located at the rear of the top of the fork 110 and serves as a basic support component. The shaft 153 is connected to the track wheel support 151. The outer ring of the bearing 152 is connected to the inner wall of the wheel body 154, and the shaft 153 is connected to the inner ring of the bearing 152, secured with a snap ring. The wheel body 154 is located within the grooved vertical track 121 and the arc-shaped track 122, allowing the wheel body 154 to roll along the vertical track 121 and the arc-shaped track 122.

[0047] When the lower bracket 130 raises the forks 110 to the preset position, the wheel body 154 of the track wheel 150 begins to contact the wheel baffle at the junction of the vertical track 121 and the arc track 122. As the lower bracket 130 continues to move, the wheel body 154 rolls along the pivot 153, causing the forks 110 to rotate around the hinge axis of the lug 160 and the lower bracket 130.

[0048] In one embodiment, the power unit 140 is a hydraulic cylinder, and the movable end of the hydraulic cylinder is connected to the bracket 130. The movable end of the hydraulic cylinder refers to the end connected to the piston inside the hydraulic cylinder. This end can generate linear motion under the action of hydraulic oil, and the raising and lowering of the bracket 130 is realized by the extension and retraction of the hydraulic cylinder.

[0049] In another embodiment, the power unit 140 includes a motor and a chain. The motor provides a power source, and the chain meshes with a sprocket on the motor's output shaft, with both ends of the chain connected to the lower bracket 130. After the motor starts, the sprocket on its output shaft begins to rotate. The rotation of the sprocket drives the chain to move through meshing with it. The movement of the chain is transmitted to the lower bracket 130, which rises or falls along a preset track or path under the drive of the chain, thereby realizing the flipping action of the linen cart.

[0050] The order-scraping platform 200 includes: a machine frame 210, a drive unit 220, at least one conveyor belt 230, a drive roller 270, a driven roller 280, a support roller 290, and a baffle assembly.

[0051] The conveyor belt 230 is mounted on the drive roller 270, driven roller 280, and idler roller 290, and is connected to the power output end of the drive device 220 via the drive roller 270. Specifically, the power output shaft of the drive device 220 drives the drive roller 270 to rotate, while the driven roller 280 supports the conveyor belt 230. The starting end of the arc-shaped track 122 is connected to the top of the vertical track 121, and the ending end of the arc-shaped track 122 is located above the front end of the conveyor belt 230, ensuring that the linens can fall smoothly onto the conveyor belt after being tumbled.

[0052] The baffle assembly is mounted on the machine frame 210. The baffle assembly consists of a front plate 240 and two side plates 250. The front plate 240 is located at the front end of the machine frame 210, and the side plates 250 are located on the sides of the machine frame 210, with their height gradually decreasing from front to back. When linens are tipped from the linen tipper 100 onto the linen-slipping platform 200, the front plate 240 prevents the linens from scattering directly forward, while the side plates 250 restrict the movement of the linens to the sides, ensuring that the linens remain on the conveyor belt 230 during transport. The gradually decreasing height of the side plates 250 also helps to provide a clear field of vision.

[0053] The forks include: fork body 111, fork frame 112, and chute 113.

[0054] The fork body 111 is located at the bottom front of the fork frame 112 and is inserted into the bottom fixing ring 310 of the linen cart 300's base frame to secure the linen cart to the forks. The track wheel 150 is located at the top rear of the fork frame 112, i.e., the track wheel support 151 is located at the top rear of the fork frame 112, and is used to guide and stabilize the forks during lifting and tilting of the linen cart 300. The lug 160 is located at the waist rear of the fork frame 112. The chute 113 is located at the top front of the fork frame 112.

[0055] The design and implementation of the linen turning and transport equipment in this application bring the following significant benefits:

[0056] Labor cost savings: Each ironing production line can save at least two linen handling workers by using linen flipping and transport equipment. This means that when multiple production lines are running at the same time, labor costs can be significantly reduced and overall work efficiency can be improved.

[0057] Space saving: The use of the order-drop platform eliminates the need for several traditional order-drop tables, thus saving at least 50% of the space. This is especially important for production environments with limited space, as it makes the production area more spacious, facilitates other production activities, and also reduces rental costs.

[0058] Increased production efficiency: The automated operation of the linen flipping and transport equipment greatly improves production efficiency, estimated to be at least 30%, making the production process smoother and more efficient.

[0059] Reduced labor intensity: After using the linen flipping and transport equipment, ironing workers no longer need to bend over to pick up linens.
