Description

Technical Field

[0001] The invention relates to the technical field of product drying, and in particular to a method for drying supporting materials based on multi-track variable speed circulation. Background Art

[0002] Modern garment drying rooms generally use highly automated production lines, which require almost no human intervention from the initial processing of clothing to the final drying process. These systems are usually equipped with advanced sensors and controllers that can monitor and adjust indoor environmental parameters such as temperature and humidity in real time to ensure the best drying effect.

[0003] In order to meet the needs of customized and matching bulk orders, garment factories usually need to dry the components of a set of clothes before sorting and assembling them. However, during the sorting and assembling process, due to the influence of environmental humidity for a long time, the humidity of the clothes after sorting cannot meet the packaging requirements. If the method of sorting and assembling the clothes first and then drying them is adopted, due to the different drying rates of different clothes, some light and thin clothes meet the drying requirements, while heavier clothes still cannot meet the drying requirements. For this reason, there is an urgent need for an improved method for drying matching clothes, so that the matching clothes can maintain the same humidity after drying. Summary of the invention

[0004] In order to solve the problems of the prior art, the present invention proposes a supporting material drying method based on a multi-track variable speed cycle, wherein a plurality of drying loop devices are provided in the drying room, and each drying loop device sets a preset cycle period of its respective target material according to a target dynamic drying rate. The drying method comprises the following steps:

[0005] S1: When each supporting material passes through the sensing device at the entrance of the drying room, the entrance partition device is controlled to open based on the sensing signal;

[0006] S2: import the current supporting materials into the differentiation track inside the drying room and read the classification information of each material;

[0007] S3: According to the classification information of each material in the supporting materials, the supporting materials are separated and respectively introduced into the drying loop device corresponding to each material;

[0008] S4: Dehumidification is performed by the dehumidifier in the drying room, and the drying loop device drives each material to rotate and dry at a target dynamic drying rate with each preset cycle;

[0009] S5: When the supporting materials are drying on the drying loop device, the materials that meet the preset drying time requirements are exported to the assimilation track inside the drying room for merging and combining;

[0010] S6: When the combined supporting materials on the assimilation track pass through the sensing device at the exit of the drying room, the exit partition device is controlled to open based on the sensing signal and the current supporting materials are exported.

[0011] Furthermore, the entrance partition device and the exit partition device remain in a closed state when no sensing signal is received.

[0012] Furthermore, in the step S1, when the materials in the drying room are in full load drying process, the entrance partition device remains in a closed state.

[0013] Furthermore, in the step S2, the material classification information is read by reading the information recording carrier on the material mounting device.

[0014] Furthermore, a temporary storage device connected to the differentiation track is provided on the outside of the drying room entrance, and the temporary storage device is used to store various supporting materials waiting in line.

[0015] Furthermore, a temporary storage device connected to the assimilation track is provided on the inner side of the drying room exit, which is used to intercept and store various materials on the assimilation track, and release the supporting materials to the induction device at the exit after they are combined into supporting materials.

[0016] Furthermore, the drying room is also provided with a fast lead-out track directly connected between the differentiation track and the assimilation track. When the supporting materials do not need to be dried, the drying process is skipped through the fast lead-out track and the materials directly enter the assimilation track as a whole.

[0017] Furthermore, the execution information of whether the supporting materials are to be dried is obtained by reading the information recording carrier on the material mounting device.

[0018] Furthermore, the preset cycle period is obtained by the following formula:

[0019]

[0020] In the formula, is the dynamic drying rate, is a constant related to air velocity, temperature and humidity, The effective surface area of ​​the material, is the target humidity, It is the equilibrium humidity when the material reaches equilibrium with the surrounding air. is the initial humidity of the material, For time, For the preset cycle period, The number of rotations is adjusted according to actual needs.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] (1) The method for drying supporting materials based on multi-track variable speed circulation described in the present invention is to set drying loop devices with different cycle periods in the drying room according to the different dynamic drying rates of the materials, so that the supporting materials can maintain a consistent dynamic drying rate during the drying process of the corresponding drying loop devices in the drying room;

[0023] (2) It can meet the user's needs to execute the next process simultaneously with the supporting materials, without the need to dry them before performing sorting and matching operations, thus avoiding the humidity changes that may be caused by subsequent processing. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Figure 1 It is a method for drying supporting materials based on multi-track variable speed circulation;

[0025] Figure 2 This is a schematic diagram of the drying room structure. DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] In order to ensure that each garment maintains a uniform humidity after drying in a drying method of first sorting and combining the garments and then drying them, and to avoid over-drying or under-drying, the present invention proposes a method for drying the garments based on a multi-track variable speed cycle, such as Figure 2 As shown, a plurality of drying loop devices are arranged in the drying room using the drying method of the present invention, and the drying operation is realized by dehumidifying with a dehumidifier. Each drying loop device sets a preset cycle period of its own target material according to the target dynamic drying rate. The materials here are different objects in matching clothing (such as matching suits, trousers, shirts of different styles, etc.) in this embodiment. Under the setting of the preset cycle period, Figure 1 As shown, the drying method of the present invention comprises the following steps:

[0028] S1: When each supporting material passes through the sensing device at the entrance of the drying room, the entrance partition device is controlled to open based on the sensing signal;

[0029] S2: import the current supporting materials into the differentiation track inside the drying room and read the classification information of each material;

[0030] S3: According to the classification information of each material in the supporting materials, the supporting materials are separated and respectively introduced into the drying loop device corresponding to each material;

[0031] S4: Dehumidification is performed by the dehumidifier in the drying room, and the drying loop device drives each material to rotate and dry at a target dynamic drying rate with each preset cycle;

[0032] S5: When the supporting materials are drying on the drying loop device, the materials that meet the preset drying time requirements are exported to the assimilation track inside the drying room for merging and combining;

[0033] S6: When the combined supporting materials on the assimilation track pass through the sensing device at the exit of the drying room, the exit partition device is controlled to open based on the sensing signal and the current supporting materials are exported.

[0034] In the drying method proposed by the present invention, in order to avoid the drying room from being fully loaded, the pre-sorted and assembled supporting materials will first be queued at the entrance temporary storage device outside the entrance of the drying room. Only after receiving the release instruction issued by the system, the supporting materials will be released one by one to the entrance partition device. When the sensing device senses that the material has passed, the system controls the entrance partition device to open according to the sensing signal, and the supporting materials enter the differentiation track in the drying room through the opened entrance partition device.

[0035] When the supporting materials enter the differentiation track, the information recording carrier (such as QR code, barcode, NFC, etc.) on the material mounting device will be read to obtain information such as material classification information and whether to perform drying processing. In the case of needing to perform drying processing, the system imports different materials into different drying loop devices according to the material classification information. On different drying loop devices, the present invention sets different preset cycle periods so that different materials can maintain the same drying rate during the drying process.

[0036] In a static state, the drying rate of materials is related to air flow rate, temperature, humidity, material and surface area. Under the same environment, the different materials and surface areas of the materials result in different drying rates. If the material is in motion, the change in air flow rate will cause the material to lose moisture faster per unit time. If the preset cycle period of the corresponding drying loop device is set based on the properties of different materials (that is, the rotation speed changes), it can be achieved that different materials can maintain the same drying rate during the drying process.

[0037] To establish a cycle , Target humidity and dynamic drying rate We need to consider the physical changes of clothes during the dynamic drying process. It can be expressed as:

[0038]

[0039] In the formula, It is the equilibrium humidity when the material reaches equilibrium with the surrounding air. is a constant related to air velocity, temperature and humidity, The effective surface area of ​​the material.

[0040] Then, the change of material humidity over time can be expressed as:

[0041]

[0042] Will Substituting into the above formula, we can get:

[0043]

[0044] In order to solve the change of humidity over time, the above differential equation can be integrated. Assume that the initial time is , initial humidity of material , then:

[0045]

[0046] Integrating both sides, we get:

[0047]

[0048] The solution is:

[0049]

[0050] Further sorting, we get:

[0051]

[0052] Then, in a complete rotation cycle The humidity change of the material It can be expressed as:

[0053]

[0054] Will Substitute the expression into the equation and we get:

[0055]

[0056] therefore:

[0057]

[0058] So, suppose we need to The humidity of clothes is reduced from Reduce to target humidity , then:

[0059]

[0060] The solution is:

[0061]

[0062] In a complete rotation cycle The humidity change of the material should be large enough to ensure that in the total time Reach target humidity , so the rotation period Should meet:

[0063]

[0064] Among them, N is the number of rotations adjusted according to actual needs. So, in summary, the cycle period , Target humidity and dynamic drying rate The relationship between can be expressed as:

[0065]

[0066] Then, to ensure that the dynamic drying rates of different materials remain consistent, the air flow rate factor in the k value can be adjusted to obtain the preset cycle period required for different materials.

[0067] When multiple materials of the same type are dried on the same drying loop device, if any of the materials reaches the preset drying time requirement ( ), the system can export it to the communication track inside the drying room, and transport it to the temporary storage device connected to the assimilation track at the exit of the drying room for temporary storage. After waiting for other supporting materials to arrive at the temporary storage device, the system will issue a release signal to release the recombined supporting materials to the induction device at the exit, and control the exit partition device to open and export the current supporting materials based on the induction signal.

[0068] For situations where drying is not required, the present invention further provides a quick export track directly connected between the differentiation track and the assimilation track in the drying room. When the supporting materials do not need drying, the quick export track skips the drying process and directly enters the assimilation track as a set.

[0069] During the drying process, the corresponding partition device will only be opened when a sensing signal is received, thereby ensuring that the drying room space is relatively closed and that the drying efficiency is not affected by the external environment.

[0070] To summarize, the supporting material drying method based on multi-track variable speed circulation described in the present invention is to set drying loop devices with different cycle periods in the drying room according to the different dynamic drying rates of the materials, so that the supporting materials can maintain a consistent dynamic drying rate when entering the drying room and undergoing drying treatment in their respective corresponding drying loop devices.

[0071] It meets the needs of users to carry out the next process simultaneously with the supporting materials, without the need to dry them before performing sorting and matching operations, thus avoiding the humidity changes that may be caused by subsequent processing.
