Description

Technical Field

[0001] This invention relates to the field of textile testing technology, and in particular to an automatic detergent bead feeding device for testing color fastness to washing. Background Technology

[0002] Colorfastness to Washing is one of the most important properties of textiles. It refers to the degree of color change of colored fabrics after a certain washing process in a specific solution with a certain temperature and a certain bath ratio for a certain period of time, and the degree of staining of various fiber fabrics.

[0003] Water wash fastness testing methods are divided into water wash fastness, soap wash fastness, and chlorine bleach fastness tests. The general procedure involves attaching a specific size lining fabric to the sample, sewing the sample along its short side to form a composite sample, and then placing it in a sealed container with detergent. The sample is then mechanically stirred while maintaining a specified temperature and time. During the test, washing beads such as steel balls are often used to simulate prolonged washing.

[0004] Therefore, before conducting a colorfastness test, it is generally necessary to prepare a soaping cup containing a consistent number of steel balls that meet the standard requirements. Currently, the procedure involves manually counting a certain number of steel balls using a fixture, and then manually pouring them into the soaping cup. However, manual operation is time-consuming, and the number of steel balls can easily be incorrect due to operator negligence. Furthermore, the required number of steel balls varies under different test standards, and relying on the operator's memory can easily lead to oversights. In addition, manual steps cannot be traced back to the data, and it is impossible to quickly identify and correct any non-compliance, which affects the accuracy of the test. Summary of the Invention

[0005] The present invention aims to provide an automatic detergent bead feeding device for water wash fastness testing. The device automates the process of adding detergent beads, avoiding situations where the number of detergent beads does not meet the requirements due to operator error, simplifying the operation steps, improving testing efficiency, and making the test data traceable.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows:

[0007] An automatic detergent bead feeding device for water wash color fastness testing includes a feeding module, a feeding module, and a control module. The feeding module is used to feed detergent beads and continuously deliver them into the feeding module. The control module operates the feeding module to feed a fixed amount of detergent beads into a soaping cup. The feeding module includes a guide rail, a first stop lever, and a second stop lever. The guide rail is connected to the feeding module and forms an angle with the horizontal plane. The side of the guide rail connected to the feeding module is higher, and the side away from the feeding module is lower. The first stop lever is located at the end of the guide rail away from the feeding module, and the second stop lever is located in the middle section of the guide rail.

[0011] In another preferred embodiment of the present invention, the distance between the first stop lever and the second stop lever in the direction of the guide rail is d. x , n*R≤d x <(n+1 / 2)*R, where n is the number of detergent beads to be put into the soap cup at one time, and R is the diameter of a single detergent bead.

[0012] In another preferred embodiment of the present invention, the automatic detergent dispenser further includes a recording module, which includes a memory and a third sensor. The third sensor is used to detect the number of detergent beads dispensed into the soap cup and send the detergent bead quantity data to the memory.

[0013] In another preferred embodiment of the present invention, the third sensor is a photoelectric sensor, and the photoelectric sensing head of the third sensor is aligned with the lower end of the guide rail away from the discharge port to detect the number of falling washing beads.

[0014] In another preferred embodiment of the present invention, the third sensor is a pressure sensor, which is installed at the bottom of the soap cup and measures the mass change of the soap cup before and after the detergent beads are added.

[0015] In another preferred embodiment of the present invention, the number of washing beads is also sent to the controller, which determines whether the number of washing beads meets the requirements.

[0016] In another preferred embodiment of the present invention, the feeding module is a vibratory feeder.

[0041] To make the objectives and technical solutions of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, back, bottom, and top, are only for reference to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present invention.

[0042] Figure 1 This is a schematic diagram of the automatic detergent bead feeding device for water wash fastness testing according to the present invention. Figure 1 As shown, the automatic detergent pod dispensing device includes a feeding module 1, an dispensing module 2, and a control module 3. The feeding module 1 is used to put in detergent pods and continuously feed them into the dispensing module 2. The control module 3 operates the dispensing module 2 to dispense a fixed amount of detergent pods into the soap cup C.

[0043] Figure 2 For labeling Figure 1 A schematic diagram of each component. (For example...) Figure 2As shown, the feeding module 1 includes a hopper 11 and a discharge port 12. The hopper 11 is used to hold washing beads, which are then discharged from the discharge port 12. The feeding module 1 is preferably a vibratory feeder. A vibratory feeder is an auxiliary feeding device for automatic assembly or processing machinery, capable of arranging materials in an orderly manner. The hopper of the vibratory feeder has a pulse electromagnet underneath, which causes the hopper to vibrate vertically. An inclined spring plate drives the hopper to oscillate around its vertical axis. Due to this vibration, the material in the hopper rises along a spiral track, automatically entering the assembly or processing position in a uniform state as required. For the washing beads to be added in this invention, the operator only needs to place the washing beads into the hopper of the vibratory feeder. After turning on the vibratory feeder, it will sequentially lift the washing beads in the hopper along the spiral track to the discharge port. Steel beads are commonly used in water wash fastness testing, although there are also test standards using rubber beads. Spherical materials are well-suited for conveying using a vibratory feeder.

[0044] The feeding module 2 includes a guide rail 21, a first stop bar 22, and a second stop bar 23. The guide rail 21 is connected to the discharge port 12 and forms an angle with the horizontal plane. The side of the guide rail 21 connected to the discharge port 12 is higher, and the side away from the discharge port 12 is lower. The lower part of the guide rail 21 away from the discharge port 12 is aligned with the position where the soap cup C is placed. After the soap cup C is placed, the lower part of the guide rail 21 away from the discharge port 12 is aligned with the mouth of the soap cup C. The guide rail 21 can be a V-groove, cylinder, semi-circular groove, rod-shaped groove, etc. The first stop bar 22 is located at the end of the guide rail 21 away from the discharge port 12, and the second stop bar 23 is located in the middle section of the guide rail 21. The distance between the first stop bar 22 and the second stop bar 23 in the direction of the guide rail 21 is equal to or slightly greater than the middle length of the number of detergent beads to be fed when arranged on the guide rail 21. The control module 3 controls the opening and closing of the first stop lever 22 and the second stop lever 23. Initially, the first stop lever 22 closes the outlet of the guide rail 21, and the second stop lever 23 is open. Washing beads output from the discharge port 12 enter the guide rail 21 and are blocked by the second stop lever 23, accumulating sequentially on the guide rail 21. When a sufficient number of washing beads have accumulated on the guide rail 21, the second stop lever 23 closes, blocking subsequent washing beads from entering. Then, the first stop lever 22 opens, and the washing beads between the first stop lever 22 and the second stop lever 23 are sequentially added into the soap cup C. Furthermore, due to the distance between the first stop lever 22 and the second stop lever 23, the number of washing beads in both is equal to the required number to be added. After addition, the first stop lever 22 closes, and the second stop lever 23 opens. The washing beads blocked by the second stop lever 23 slide down the guide rail 21 in one go and are blocked by the first stop lever 22.

[0045] Preferably, the position of the second stop lever 23 in the direction of the guide rail 21 is adjustable. The number of detergent beads added to the soap cup C at one time can be adjusted by adjusting the interval between the first stop lever 22 and the second stop lever 23 in the direction of the guide rail 21. Let n be the number of detergent beads to be added to the soap cup C at one time, R be the diameter of a single detergent bead, and d be the interval between the first stop lever 22 and the second stop lever 23 in the direction of the guide rail 21. x The distance between the first stop lever 22 and the second stop lever 23 in the direction of the guide rail 21 is d. x = n*R, or n*R < d x <(n+1 / 2)*R.

[0046] The control module 3 includes a control panel 31, a controller 32, a first push rod 33, and a second push rod 34. The control panel 31 is used for human-machine interaction; the operator can send commands to the controller 32 through the control panel 31. The controller 32 controls the first push rod 33 and the second push rod 34. The first push rod 33 and the second push rod 34 are respectively used to control the opening and closing of the first stop lever 22 and the second stop lever 23, and can also control the position of the second stop lever 23 on the guide rail 21. Preferably, the controller 32 has built-in data on the required number of washing beads under different test standards and the corresponding distance between the first stop lever 22 and the second stop lever 23. The operator can select a test mode through the control panel 31, and the controller 32 automatically adjusts the distance d between the stop levers according to different modes. x The control panel 31 is preferably a touch screen for easy operation. The touch screen can be used to set values ​​and select test modes. The first push rod 33 and the second push rod 34 are preferably electromagnetic push rods. Electromagnetic push rods use high-power start-up and low-power hold-up, allowing for frequent operation and long-term continuous operation. Compared with electric push rods, they have no motor or lead screw, making their structure simple and easy to maintain. The controller 32 is preferably a programmable logic controller (PLC).

[0047] Preferably, the control module 3 further includes a first sensor 35, which is used to detect whether the soap cup C is placed in the corresponding position and feeds back the detection information to the controller 32. The first sensor 35 can be a photoelectric sensor, which can be installed with the photoelectric sensor head facing upwards at the bottom of the soap cup placement position, or with the photoelectric sensor head horizontally aligned with the lower part of the soap cup wall. Furthermore, since soap cups used in water wash color fastness testing are mostly made of metal, the first sensor 35 can also be an electromagnetic sensor, installed at the bottom of the soap cup placement position. The controller 32 will only control the first stop lever 22 and the second stop lever 23 to add detergent beads when the first sensor 35 detects that the soap cup C is in the corresponding placement position.

[0048] Preferably, the control module 3 further includes a second sensor 36, which is used to detect the height of the soap cup C and feed the detection information back to the controller 32. Since different models and sizes of soap cups correspond to different testing standards in actual testing, meaning the size of the soap cups used in different testing standards differs, the required number of detergent beads can be determined by distinguishing the height of the soap cup. After the second sensor 36 detects the height of the soap cup C, the controller 32 can calculate the required distance between the first stop lever 22 and the second stop lever 23 based on the number of detergent beads to be added according to the height of the soap cup C, plus the known diameter of the detergent beads, thereby controlling the adjustment of the position of the second stop lever 23. The second sensor 36 can be a series of vertically arranged photoelectric sensors, with the photoelectric sensing heads of the photoelectric sensors facing the end of the soap cup C near the rim. By determining how many photoelectric sensors detect obstruction, the height of the rim of the soap cup C is determined, thus confirming the model of the soap cup C.

[0049] The automatic detergent dispenser of the present invention further includes a recording module 4, which is used to record test data. The recording module 4 includes a memory 41 and an I / O interface 42. Operators can input test order number data on the control panel 31 or import it through the I / O interface 42. The data is stored in the memory 41. During testing, the height of the soap cup C detected by the second sensor 36 is sent to the controller 32. The controller 32 determines the model of the soap cup C and can send the model data to the memory 41. The memory 41 maps the test order number data to the model data, allowing subsequent operators to trace the data and determine whether the correct soap cup was selected.

[0050] The recording module 4 also includes a third sensor 43, which detects the number of detergent beads added to the soap cup C and sends the detergent bead quantity data to the memory 41. The third sensor 43 can be a photoelectric sensor. When a photoelectric sensor is used, its photoelectric sensing head is aligned with the lower end of the guide rail 21 away from the discharge port 12. The detergent beads briefly block the photoelectric sensing head as they fall, allowing the number of times the signal from the third sensor 43 is blocked to determine the number of detergent beads added. Alternatively, the third sensor 43 can be a pressure sensor. When a pressure sensor is used, it is installed at the bottom of the soap cup location. By measuring the mass change of the soap cup C before and after detergent bead addition, and based on the mass of a single detergent bead, the number of detergent beads added to the soap cup C is determined. The memory 41 records the test order number, model data, and detergent bead quantity data in a one-to-one correspondence, allowing subsequent operators to trace the data and determine whether the required number of detergent beads was accurately added.

[0051] Preferably, the number of detergent beads is also sent to the controller 32, which determines whether the number of detergent beads matches the model data. If the number of detergent beads added is less than the specified amount corresponding to the model data of the soap cup, the controller 32 controls the dispensing module 2 to add the missing amount of detergent beads. If the number of detergent beads added exceeds the specified amount corresponding to the model data of the soap cup, an audible and visual signal can be sent through the control panel 31 to remind the operator to make corrections.

[0052] If the number of detergent beads to be added is too large, or if the length of the guide rail 21 prevents the addition of all detergent beads at once, multiple additions can be made. For example, if 25 detergent beads are needed, but the distance between the first stop 22 and the second stop 23 can only accommodate 10 detergent beads at the maximum adjustment range of the second stop 23, the addition can be done in three steps: two additions of 10 beads each, and one addition of 5 beads each, thus achieving the goal of adding a total of 25 detergent beads.

[0053] Furthermore, the first stop lever 22 and the second stop lever 23 can be designed to be linked, so that when one side is in the open state, the other side is in the closed state. Through the linkage design, the push rod that pushes the first stop lever 22 and the second stop lever 23 can be reduced to one.

[0054] The automatic detergent bead feeding device for water wash fastness testing according to the present invention. Figure 3 The diagram shows the operation steps of the automatic detergent bead feeding device for the water wash fastness test of the device of the present invention. The specific operation steps are as follows.

[0055] Step S1: Turn on the device. In the initial state, the first lever 22 is in the closed state and the second lever 23 is in the open state.

[0056] In step S2, washing beads are added to the hopper 11 and the washing beads are conveyed and arranged on the guide rail 21.

[0057] Step S3: Place soap cup C at the soap cup placement position, and the first sensor 35 detects that soap cup C has been placed in the predetermined position.

[0058] In step S4, the first sensor 36 detects the model C of the soap cup to determine the number of washing beads to be added, and the controller 32 controls the second lever 23 to adjust the spacing.

[0059] In step S5, the second lever 23 is closed, the first lever 22 is opened, the detergent beads are put into the soap cup C, and the third sensor 43 detects the number of detergent beads put into the soap cup C.

[0060] Step S6, the input is completed, the first gear lever 22 and the second gear lever 23 return to their initial state, and the operator takes out the soap washing cup C.

[0061] Step S7: The operator checks the recorded data in the recording module 4. If the data is correct, the operation of this device ends.

[0062] In summary, the automatic detergent bead feeding device for water wash fastness testing of the present invention realizes automatic detection of the soap cup and automatic addition of a set number of detergent beads, reducing the deviation caused by manual operation and memory, making the counting more accurate, and can trace the number of detergent beads added and the size of the soap cup corresponding to the test order number, and can retain and effectively trace the test data.

[0063] Although the present invention has been disclosed above by way of embodiments, it is not intended to limit the present invention. Anyone skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
