Description

Technical Field

[0001] This utility model relates to the field of linen conveying technology, specifically to a linen washing and conveying mechanism with an RFID reader. Background Technology

[0002] Linen is a general term used by the hotel housekeeping department to refer to towels, tablecloths, sheets, pillowcases, etc., placed in guest rooms. Hotel linen generally refers to almost everything related to "cloth" in modern hotels, including bedding such as quilts and duvet covers, cotton quilt cores, sheets and bedspreads, pillowcases and pillow cores, fitted sheets and bed skirts, bed runners and mattress protectors, as well as towel products such as face towels, hand towels, bath towels, floor mats, bathrobes, etc. It also includes tablecloths, napkins, chair covers and table skirts, shower curtains, etc.

[0003] After receiving the linens, the laundry company needs to conduct a detailed inventory of the types and quantities of linens and verify this information against the types and quantities of linens provided by the hotel to ensure consistency. This step is crucial, as it not only avoids price disputes due to discrepancies but also ensures the smooth operation of the laundry service and the accuracy of subsequent settlements.

[0004] The traditional method of manual counting has the following drawbacks: First, manually counting the types and quantities of linens consumes a lot of time and manpower, especially when the quantity of linens is large, the counting work is tedious and seriously affects the operational efficiency of the laundry company; Second, manual counting of linens is prone to errors and omissions due to fatigue or negligence, resulting in inaccurate statistical results that do not match the hotel's data, which may lead to price disputes and harm the interests of both parties.

[0025] 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. It should be noted that the description of these embodiments is intended to aid in understanding this utility model, but does not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0026] Reference Figures 1 to 4 As shown, a linen washing and conveying mechanism with an RFID reader includes a weighing conveying component 1 and a lifting conveying component 2. The weighing conveying component 1 is used to weigh the linen placed on it. When the linen reaches a set weight, the weighing conveying component 1 conveys the linen to the lifting conveying component 2. The other end of the lifting conveying component 2 extends to the inlet of the washing equipment. It also includes a baffle housing 3, which surrounds the weighing conveying component 1 and the lifting conveying component 2. An RFID reader 4 is fixed on the baffle housing 3. The RFID reader 4 is used to read the RFID chip on the linen and count its quantity.

[0027] The RFID chip contains hotel information and linen type, and the RFID chip is pre-fixed to the linen. During use, the linen is placed on the weighing and conveying assembly 1. Simultaneously, the RFID reader 4 reads the hotel information and linen type from the RFID chip on the linen and counts the quantity. When the total weight of the linens on the weighing and conveying assembly 1 reaches a set threshold, the linens are conveyed to the washing equipment via the lifting conveying assembly 2. The baffle housing 3 prevents the linens from detaching from the weighing and conveying assembly 1 or the lifting conveying assembly 2 during transport.

[0028] The weighing conveying component 1 and the lifting conveying component 2 can be driven independently by two sets of driving devices 5. In this utility model, the weighing conveying component 1 and the lifting conveying component are driven synchronously by one driving device 5, thereby reducing the overall cost of the equipment. The specific structure is as follows:

[0029] The weighing and conveying assembly 1 includes a first conveyor belt 11, a weighing sensor 12 is provided below the first conveyor belt 11, a first drive shaft 13 and a first driven shaft 14 are respectively provided on the inner two sides of the first conveyor belt 11, and a first drive wheel 15 is provided on the outside of the first conveyor belt 11.

[0030] The lifting and conveying assembly 2 includes a second conveyor belt 21. A second drive shaft 22 and a second driven shaft 23 are respectively provided on both sides of the interior of the second conveyor belt 21. A second drive wheel 24 is provided on the outside of the second conveyor belt 21.

[0031] It also includes a drive device 5, which includes a motor 51, a drive wheel 52 disposed at the output end of the motor 51, and a transmission belt 53 sleeved on the outer periphery of the drive wheel 52. The transmission belt 53 is connected to the first transmission wheel 15 and the second transmission wheel 24.

[0032] In use, the motor 51 drives the transmission belt 53 through the drive wheel 52. The transmission belt 53 drives the first transmission wheel 15 and the second transmission wheel 24 to rotate. The rotation of the first transmission wheel 15 and the second transmission wheel 24 respectively drives the first drive shaft 13 and the second drive shaft 22 to rotate, and finally drives the first conveyor belt 11 and the second conveyor belt 21 to start the conveying of linens.

[0033] Reference Figure 4 As shown, as a preferred embodiment, the second conveyor belt 21 is provided with a plurality of pushing inclined plates 211. By pushing the inclined plates 211, the fabric can be prevented from slipping off due to insufficient friction between it and the surface of the second conveyor belt 21.

[0034] The weighing and conveying assembly 1 includes two spaced-apart first aluminum alloy profiles 16, and first front adjusting blocks 17 and first rear adjusting blocks 18 disposed at the front and rear ends of the first aluminum alloy profiles 16. The two ends of the first drive shaft 13 are fixed to the first aluminum alloy profile 16 via the two first front adjusting blocks 17, and the two ends of the first driven shaft 14 are fixed to the first aluminum alloy profile 16 via the two first rear adjusting blocks 18. The first front adjusting blocks 17 and first rear adjusting blocks 18 can be slidably adjusted along the first aluminum alloy profile 16 to a suitable position and locked, allowing the first drive shaft 13 and first driven shaft 14 to cooperate in adjusting the tension of the first conveyor belt 11 to a suitable level, ensuring stable force transmission. The weighing and conveying assembly 1 also includes a first transverse aluminum alloy profile 19 connecting the first aluminum alloy profiles 16. The first aluminum alloy profiles 16 and the first transverse aluminum alloy profile 19 cooperate to form a stable frame structure. Furthermore, by using aluminum alloy profiles as the frame structure, there is no need to manufacture non-standard parts, reducing the manufacturing cost of the linen washing and conveying mechanism.

[0035] Similarly, the lifting and conveying assembly 2 includes two spaced-apart second aluminum alloy profiles 25, and a second front adjusting block 26 and a second rear adjusting block 27 disposed at the front and rear ends of the second aluminum alloy profiles 25. The two ends of the second drive shaft 22 are connected to the second aluminum alloy profile 25 through the second front adjusting block 26, and the two ends of the second driven shaft 23 are connected to the second aluminum alloy profile 25 through the second rear adjusting block 27. The lifting and conveying assembly 2 also includes a second transverse aluminum alloy profile 28 connecting the second aluminum alloy profiles 25. The second aluminum alloy profiles 25 and the second transverse aluminum alloy profiles 28 cooperate to form a stable frame structure.

[0036] The drive device 5 also includes two first adjusting plates 54 and a second adjusting plate 55, and two tensioning shafts 56 connecting the first adjusting plates 54 and the second adjusting plates 55. The tensioning shafts 56 abut against the transmission belt 53. The first adjusting plate 54 is connected to the baffle housing 3 and is adjustable in the height direction. The second adjusting plate 55 is connected to the baffle housing 3 and is adjustable in the height direction. The motor 51 is installed at the other end of the second adjusting plate 55. With the above structure, when the first adjusting plate 54 and the second adjusting plate 55 are moved up and down, the transmission belt 53 can be adjusted to a suitable tension to ensure stable force transmission.

[0037] The top surface of the baffle housing 3 is higher than the top surfaces of the first conveyor belt 11 and the second conveyor belt 21, and this height is greater than 50cm. By meeting this parameter, large-sized straw cloths, such as bed sheets and duvet covers, can be prevented from detaching from the first conveyor belt 11 or the second conveyor belt 21 during the conveying process. The baffle housing 3 is provided with a feeding notch 31, and the RFID reader 4 is set at the feeding notch 31. This makes it convenient for workers to pass through the RFID reader 4 when feeding the straw cloth into the first conveyor belt 11, thereby aligning the RFID tag on the straw cloth with the RFID reader 4 for easy information identification.

[0038] It also includes a support plate 6 and a reinforcing rib plate connecting the support plate 6 and the baffle housing 3. The RFID reader 4 is fixed to the support plate 6, and the RFID reader 4 is supported and fixed by the cooperation of the support plate 6 and the reinforcing rib plate.

[0039] The first step is linen washing. The linen washing and conveying mechanism automatically transports the linens to the washing equipment. During the process of placing the linens one by one onto the weighing and conveying component 1, the quantity is counted. Assuming the washing equipment's single washing capacity is 50 kg, the weighing sensor 12 is set to detect 50 kg, triggering a signal to activate the weighing and conveying component 1 and the lifting and conveying component 2, thus automatically conveying the linens into the washing equipment. The weighing sensor 12 is located at the lower end of the first aluminum alloy profile 16 to ensure accurate weighing of the linens.
