Abstract
Description
Technical Field
[0001] The utility model relates to linen processing, in particular to a linen taking and feeding mechanism. Background Art
[0002] Hotel linens typically refer to fabrics like bed sheets, duvet covers, and fitted sheets. Due to the scale of hotel operations, linens need to be centrally managed, making storage and portability inconvenient. Because bed sheets and fitted sheets are so large when unfolded, they often need to be folded by hanging the edges on handles.
[0003] The grippers for folding linen are usually electrified grippers, which can easily cause harm to personnel if they are not operated properly or there is an electrical failure. Utility Model Content
[0004] This utility model aims to provide a safer linen feeding and retrieving mechanism. The structure part involving manual operation is purely mechanical, avoiding personal injury caused by automated machinery. The specific scheme is as follows:
[0005] A linen feeding and taking mechanism includes a feeding mechanism and a taking mechanism. The taking mechanism is slidably arranged on a Y-axis slide rail. The feeding mechanism is located at one end of the Y-axis slide rail.
[0006] The feeding mechanism includes a spring clamp, which is provided with a U-shaped fixed clamp block and a rotating clamp rotatably mounted on the fixed clamp block, and a tension spring is connected between the rotating clamp and the fixed clamp block;
[0007] The material-retrieving mechanism is provided with a base, a pneumatic clamp and a rolling body. The base is slidably installed on the Y-axis slide rail, and the pneumatic clamp and the rolling body are fixedly installed on the base. The sliding material-retrieving mechanism drives the rotating clamp to rotate and open the spring clamp through the rolling body.
[0008] Furthermore, the feeding mechanism is provided with a fixed block, on which two pairs of spring clamps are installed in parallel. The picking mechanism slides on the Y-axis slide rail so that the pneumatic clamp is located between the two pairs of spring clamps.
[0009] The material taking mechanism is equipped with two rolling bodies which respectively cooperate with the spring clamping jaws, and the rolling bodies are located on both sides of the pneumatic clamping jaws.
[0010] Furthermore, a driving motor, a synchronous belt or a chain for driving the material picking mechanism to slide is provided on the Y-axis slide rail.
[0011] Furthermore, the linen feeding and taking mechanism is also provided with an X-axis slide rail, the fixed block is slidably installed on the X-axis slide rail through a bracket, and the feeding mechanism slides on the X-axis slide rail to one end of the Y-axis slide rail.
[0012] Furthermore, the rolling body is a roller or a ball.
[0013] This utility model replaces the manually operated spring clamp with a fully mechanical design. The clamp opens by manually pressing and rotating it, and automatically closes to secure the linen when released. The clamp has no electrical components, ensuring operator safety during the process. Furthermore, the retrieving mechanism automatically opens the clamp by sliding, releasing the connection between the clamp and the linen without manual intervention, improving efficiency while further ensuring safety.

[0021] In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features known in the art are not described to avoid confusion with the present invention.
[0022] In order to fully understand the present invention, detailed steps and detailed structures will be provided in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below. However, in addition to these detailed descriptions, the present invention may also have other implementation methods.
[0023] The utility model provides a linen feeding and retrieving mechanism, which includes a feeding mechanism 100 and a retrieving mechanism 200. The retrieving mechanism 200 is slidably mounted on a Y-axis slide rail 300. The feeding mechanism 100 includes a spring clamp 110, which is provided with a U-shaped fixed clamp block 111 and a rotating clamp 112 rotatably mounted on the fixed clamp block 111. A tension spring 113 is connected between the rotating clamp 112 and the fixed clamp block 111. The retrieving mechanism 200 includes a base 210, a pneumatic clamp 220, and a rolling element 230. The base 210 is slidably mounted on the Y-axis slide rail 300, and the pneumatic clamp 220 and the rolling element 230 are fixedly mounted on the base 210.
[0024] In an optional embodiment, if Figure 4 As shown, the feeding mechanism 100 is equipped with a fixed block 101, on which two pairs of spring jaws 110 are mounted in parallel. The picking mechanism 200 slides on the Y-axis slide 300, so that the pneumatic jaws 220 are located between the two pairs of spring jaws 110. When the pneumatic jaws 220 grab the linen, the spring jaws 110 on both sides clamp the linen, effectively improving the pneumatic jaws 220's grab success rate. Accordingly, the picking mechanism 200 is also equipped with two rolling bodies 230 that respectively cooperate with the spring jaws 110. The rolling bodies 230 are located on both sides of the pneumatic jaws 220.
[0025] In an optional embodiment, a driving motor, a synchronous belt or a chain is provided on the Y-axis slide rail 300 for driving the material picking mechanism 200 to slide along the Y-axis.
[0026] In an optional embodiment, if Figure 3 As shown, the linen feeding and retrieving mechanism also features an X-axis rail 400. The fixed block 101 is slidably mounted on the X-axis rail 400 via a bracket 120. The feeding mechanism 100 slides along the X-axis rail 400 to one end of the Y-axis rail 300. Workers hang linens using the feeding mechanism 100, located at one end of the X-axis rail 400, providing greater operating space and safety. After hanging the linens, the feeding mechanism 100 slides to the other end of the X-axis rail 400, where it mates with the retrieving mechanism 200 to transfer the linens.
[0027] In an optional embodiment, the rolling body 230 is a roller or a ball.
[0028] The working process of the utility model is as follows:
[0029] 1) Manually press the rotating jaw 112 to open the spring jaw 110, then insert the corner of the linen into the opening of the U-shaped fixed clamp 111, then release the rotating jaw 112, and the rotating jaw 112 automatically resets under the action of the reset spring 113 to clamp the linen on the spring jaw 110.
[0030] 2) The feeding mechanism 100 slides along the X-axis slide rail 400 to one end of the Y-axis slide rail 300 .
[0031] 3) The retrieving mechanism 200 slides on the Y-axis rail 300 toward the feeding mechanism 100 until the linen is positioned within the opening of the pneumatic gripper 220. The pneumatic gripper 220 closes and grips the linen. The retrieving mechanism 200 then continues to slide along the Y-axis rail 300. During this sliding process, the rolling element 230 at the end of the base 210 comes into contact with the rotating gripper 112, pressing the rotating gripper 112 to rotate it, thereby opening the spring gripper 110 and disengaging the spring gripper 110 of the feeding mechanism 100 from the linen. This transfers the linen captured by the feeding mechanism 100 to the pneumatic gripper 220 of the retrieving mechanism.
[0032] The advantages of the present invention are:
[0033] 1. High safety. Linen is manually secured to the spring clamps. To prevent injuries to workers caused by automated clamps, the present invention replaces the manually operated spring clamps with a fully mechanical design. The clamps are opened by manually pressing and turning them, and automatically close to secure the linen when released. This part of the structure does not contain any electrical components, greatly improving the operator's personal safety during the process of installing the linen on the spring clamps.
[0034] 2. After the corners of the linen are fixed on the spring clamp, the feeding mechanism slides toward the spring clamp and grabs the linen through the pneumatic clamp. After the pneumatic clamp grabs the linen, the feeding mechanism continues to slide so that the rolling body drives the rotating clamp to rotate, and then opens the spring clamp. The linen can be separated from the spring clamp without manual intervention, further ensuring the personal safety of the operator.
[0035] 3. The retrieving mechanism drives the rotating jaw to rotate and open the spring jaw through the rolling body. The rotation of the rotating jaw is achieved through rolling friction and sliding friction, which makes the rotation of the rotating jaw smoother, reduces wear and improves service life.
[0036] 4. The feeding mechanism has a simple structure, low procurement cost, low failure rate and easy maintenance.
[0037] The above describes the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the above-mentioned specific embodiments, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-mentioned disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the present invention without departing from the scope of the technical solution of the present invention, or modify them into equivalent embodiments with equivalent changes, which does not affect the essential content of the present invention. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention that do not depart from the content of the technical solution of the present invention are still within the scope of protection of the technical solution of the present invention.
