Description

Technical Field

[0001] This utility model relates to the field of linen packaging technology, specifically to a linen packaging device 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] The laundry company collects linens from multiple hotels, washes them, and then returns them to the hotels. After washing, the linens are sorted according to the hotel information and type of linen. The sorted linens are then manually folded and counted, and finally automatically bundled by a bundling machine to form delivery units that meet the hotel's requirements.

[0004] However, the above process has the following technical drawbacks:

[0005] High statistical error rate: Manual counting is easily affected by factors such as fatigue and environmental interference, which may lead to deviations in the number of single bundles or errors in the total number of hotel linens. Frequent rework and verification are required, and customer complaints and compensation caused by incorrect statistics further increase operating costs.

[0006] Data traceability is difficult: manual records are made on paper or in scattered spreadsheets, which are easy to lose and difficult to link with linen batches and customer information, making it impossible to achieve full-process data monitoring. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to propose a linen packing device with an RFID reader to solve the problems mentioned in the background section above.

[0008] This utility model is achieved through the following technical solution:

[0009] A linen packing device with an RFID reader includes a strapping machine body, a packing operation table, and a controller. The controller is used to control the strapping machine body to start and stop the packing operation. Multiple linens are bundled on the packing operation table. Each linen is equipped with an RFID chip, which stores hotel information and linen type. The packing operation table is equipped with an RFID reader, which reads the hotel information and linen type from the RFID chip placed on the packing operation table and transmits it to the controller for quantity counting. When the hotel information and linen type match, and the counted number of linens reaches a set quantity, the controller controls the strapping machine body to start the packing operation.

[0010] Furthermore, it also includes a linen folding mechanism, which includes a first conveyor belt, a second conveyor belt and a third conveyor belt arranged in sequence, a first rotating plate that rotates inward on the left and right sides of the second conveyor belt, a third conveyor belt having a plurality of interval grooves, and a second rotating plate arranged at intervals and rotating inward in the interval grooves, and the strapping machine body being disposed at the discharge end of the third conveyor belt.

[0011] Furthermore, the strapping machine body also includes a guiding device and an opening and closing mechanism fixed to the guiding device. The opening and closing mechanism is located between the third conveyor belt and the packaging operation table. The packaging operation table is provided with a fourth conveyor belt and a fifth conveyor belt at the front and rear ends of the guiding device. The controller is used to control the operation of the opening and closing mechanism, the fourth conveyor belt and the fifth conveyor belt.

[0012] Furthermore, the opening and closing mechanism includes a first longitudinal beam and a second longitudinal beam arranged at intervals, a crossbeam connecting the first longitudinal beam and the second longitudinal beam, a first connecting plate rotatably connected to the first longitudinal beam, a second connecting plate rotatably connected to the second longitudinal beam, a first support plate rotatably connected to the first connecting plate, and a second support plate rotatably connected to the second connecting plate. The first support plate and the second support plate are respectively provided with guide rods embedded in the crossbeam. The crossbeam is provided with a first cylinder, and the output end of the first cylinder is provided with an L-shaped first connecting rod. The first connecting plate is fixed with a first rotating shaft rotatably connected to the first connecting rod. The crossbeam is provided with a second cylinder, and the output end of the second cylinder is provided with an L-shaped second connecting rod. The second connecting plate is fixed with a second rotating shaft rotatably connected to the second connecting rod.

[0013] Furthermore, the discharge end of the fifth conveyor belt is equipped with a storage box.

[0014] Furthermore, it also includes a weighing sensor for weighing the storage box, the weighing sensor being connected to the controller.

[0015] The beneficial effects of this utility model are as follows: A linen packing device with an RFID reader includes a strapping machine body, which includes a packing operation table and a controller. The controller is used to control the strapping machine body to start and stop the packing operation. Multiple linens are bundled on the packing operation table. Each linen is equipped with an RFID chip, which stores hotel information and linen type. The packing operation table is equipped with an RFID reader, which reads the hotel information and linen type from the RFID chip placed on the packing operation table and transmits it to the controller for quantity counting. When the information and type of linens are consistent, and the counted quantity of linens reaches the set quantity, the controller controls the strapping machine to start the packing operation. With the cooperation of the RFID chip on the linens, the RFID reader, and the controller, a fully automated closed loop of "verifying the type of linens and hotel information - automatically counting the quantity - automatically packing" is realized. Compared with the manual process, the processing time of a single delivery unit is shortened, the throughput frequency of the linen packing device is increased, and the error rate of quantity counting is reduced. The RFID chip of each piece of linen serves as a unique identifier, and its flow trajectory (including counting and packing time nodes) is accurately recorded in the system database to realize full-process data monitoring.

Detailed Implementation

[0022] 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.

[0023] Reference Figure 1 As shown, a linen packing device with an RFID reader / writer 2 includes a strapping machine body 1, which includes a packing operation table 11 and a controller. The controller is used to control the strapping machine body 1 to start and stop the packing operation. Multiple linens are bundled on the packing operation table 11. Each linen is equipped with an RFID chip, which stores hotel information and linen type. The packing operation table 11 is equipped with an RFID reader / writer 2, which reads the hotel information and linen type from the RFID chip placed on the packing operation table 11 and transmits it to the controller for quantity counting. When the hotel information and linen type are consistent and the counted linen quantity reaches a set quantity, the controller controls the strapping machine body 1 to start the packing operation.

[0024] In use, linens are manually folded and then stacked on the packing workbench 11. Each piece of linen has an RFID chip as a unique identifier, storing hotel information and linen type information. The RFID reader 2 reads the RFID chip and counts the number of linens. When the number of linens reaches the delivery unit required by the hotel, the controller will notify the operator through an audible or visual alert, or automatically perform the packing operation. Compared to manual processes, this reduces the processing time for a single delivery unit, eliminates the need for manual counting, and lowers the error rate in quantity statistics. The RFID reader 2 can transmit the read information (including counts and packing time points) to a computer database, enabling full-process data monitoring.

[0025] The strapping machine body 1 includes the following structures: a strapping tape supply device that provides strapping tape and guides it to the strapping position; a guide device 12 that guides the strapping tape to be correctly wrapped around the item, ensuring that the strapping tape does not deviate from the predetermined path; a tightening head that tightens the strapping tape, allowing it to tightly wrap around the item; and a transmission device including a motor, gears, chains, belts, etc., used to transmit power to the various working parts, enabling them to work in coordination. The above is existing technology for the strapping machine body 1 and will not be elaborated further. The improvement of this utility model lies in controlling the operation of the strapping machine body 1 through a controller and connecting the controller to an RFID reader / writer 2 to achieve automated packaging operations.

[0026] Reference Figure 2 As shown, the system also includes a linen folding mechanism 3, which comprises a first conveyor belt 31, a second conveyor belt 32, and a third conveyor belt 33 arranged in sequence. The second conveyor belt 32 has first rotating plates 34 that rotate inwards on both sides. The third conveyor belt 33 has several interval grooves 331, and each interval groove 331 contains second rotating plates 35 arranged at intervals and rotating inwards. The strapping machine body 1 is located at the discharge end of the third conveyor belt 33. The first conveyor belt 31, second conveyor belt 32, and third conveyor belt 33 are driven by a transmission device, which includes a motor, gears, chains, and belts (i.e., the first conveyor belt 31, second conveyor belt 32, or third conveyor belt 33 are connected). The connection of the transmission device is prior art and will not be described further here. Furthermore, the first rotating plate 34 can be rotated by a third cylinder 36, and the second rotating plate 35 can be rotated by a fourth cylinder 37.

[0027] In use, the linen is laid flat on the first conveyor belt 31 by hand, and then the first conveyor belt 31 transports the linen to the second conveyor belt 32. When the linen reaches the set position of the second conveyor belt 32, that is, between the two first rotating plates 34, the first rotating plates 34 fold the left and right sides of the linen inward. Then the second conveyor belt 32 transports the linen to the set position of the third conveyor belt 33, that is, between the two second transmission plates. The second rotating plates 35 fold the front and back sides of the linen inward, so as to fold the linen into the delivery unit size that meets the hotel's requirements.

[0028] Reference Figure 2 and Figure 3 As shown, the linen is automatically folded by the linen folding mechanism 3. After folding, the linen can be automatically stacked and placed on the packing operation table 11 of the strapping machine body 1 through the following structure.

[0029] Specifically, the strapping machine body 1 also includes a guide device 12 and an opening and closing mechanism 4 fixed to the guide device 12. The opening and closing mechanism 4 is located between the third conveyor belt 33 and the packing operation table 11. The packing operation table 11 is provided with a fourth conveyor belt 111 and a fifth conveyor belt 112 at the front and rear ends of the guide device 12. The controller is used to control the operation of the opening and closing mechanism 4, the fourth conveyor belt 111 and the fifth conveyor belt 112.

[0030] In use, the linens are automatically folded by the linen folding mechanism 3. Then, under the action of gravity, the linens are conveyed by the third conveyor belt 33 to the dropping opening and closing mechanism 4. The controller controls the opening and closing mechanism 4 to open quickly, so that the linens fall smoothly to the fourth conveyor belt 111. The RFID reader 2 reads the RFID chip of the linens and counts the number. When the number of linens reaches the delivery unit that meets the hotel's requirements, the controller controls the fourth conveyor belt 111 and the fifth conveyor belt 112 to convey the linens to the guide device 12. Then, the controller controls the strapping machine body 1 to start the packing operation. After the packing is completed, the controller controls the fourth conveyor belt 111 and the fifth conveyor belt 112 to output the linens.

[0031] The discharge end of the fifth conveyor belt 112 is equipped with a collection box (not shown in the figure). The collection box is used to receive the packaged linen delivery units. It also includes a weighing sensor for weighing the collection box, which is connected to the controller. Since the linens are of the same type, their weights are similar. Therefore, through dual verification by the weighing sensor and the RFID reader 2, it is possible to detect whether the RFID chip has fallen off. If the weight measured by the weighing sensor does not match the quantity counted by the RFID reader 2, it indicates that an RFID chip may have fallen off. The system can issue an alarm in a timely manner to remind staff to check and handle the situation, thereby ensuring the integrity and reliability of the data.

[0032] Specifically, refer to Figure 4 As shown, the opening and closing mechanism 4 includes a first longitudinal beam 41 and a second longitudinal beam 42 arranged at intervals, a crossbeam 43 connecting the first longitudinal beam 41 and the second longitudinal beam 42, a first connecting plate 411 rotatably connected to the first longitudinal beam 41, a second connecting plate 421 rotatably connected to the second longitudinal beam 42, a first support plate 412 rotatably connected to the first connecting plate 411, and a second support plate 422 rotatably connected to the second connecting plate 421. The first support plate 412 and the second support plate 422 are respectively provided with guide rods 44 embedded in the crossbeam 43. The crossbeam 43 is provided with a first cylinder 413, and the output end of the first cylinder 413 is provided with an L-shaped first connecting rod 414. The first connecting plate 411 is fixedly provided with a first rotating shaft 415 rotatably connected to the first connecting rod 414. The crossbeam 43 is provided with a second cylinder 423, and the output end of the second cylinder 423 is provided with an L-shaped second connecting rod 424. The second connecting plate 421 is fixedly provided with a second rotating shaft 425 rotatably connected to the second connecting rod 424. The controller controls the first cylinder 413 and the second cylinder 423 to retract synchronously. The first cylinder 413 drives the first connecting rod 414 to move, so that the first pallet 412 moves toward the first longitudinal beam 41. The second cylinder 423 drives the second connecting rod 424 to move, so that the second pallet 422 moves toward the second longitudinal beam 42. As a result, the folded linen falls along the first pallet 412 and the second open gap onto the fourth conveyor belt 111.
