Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of elastic band processing, in particular to a control method for identifying elastic band with logo. BACKGROUND

[0002] Elastic band is usually sewn at the waistband ring opening to make the waistband flexible and adjustable within a small range of human waist circumference, so that people can wear it comfortably. Elastic band can be wrapped in the trousers and sewn or directly sewn outside the trousers as a waistband. For the use as a waistband, more and more manufacturers will add LOGO (logo) on it, which not only increases the beauty but also has good commercial propaganda effect. When the elastic band is used as a waistband, the elastic band usually has a LOGO, and the position of the LOGO has requirements. Such elastic band is in increasing demand, and whether it can be efficiently produced has become a concern for many manufacturers. Such elastic band currently has the following ways: 1. Manual semi-automatic cutting: that is, production workers use semi-automatic devices, and the LOGO position is observed by the human eye, and the elastic band is cut manually. This way, the production workers need to keep their attention to judge the LOGO position all the time, and then use their hands to cut. After a long time, it is extremely tiring for the workers' brain and body, and the cut elastic band needs to be processed and sewn in the next process, so the efficiency of this way is low; 2. Full-automatic docking type: that is, through mechanical structure, automatic completion of feeding, cutting, sewing and collecting of the elastic band. One worker can take care of multiple machines at the same time, and the production efficiency is high, but this way has the requirement of effectively identifying the position of the LOGO when making the elastic band with LOGO.

[0003] In the prior art, an image sensor is used to collect the logo pattern and form a pattern template in the control system, and the raw material belt is conveyed. When the image sensor detects the same logo pattern as the pattern template, the control system positions the raw material belt. Such device is relatively expensive and is not conducive to popularization and application. SUMMARY

[0004] The purpose of the present application is to provide a control method for identifying elastic band with logo to solve the problems of low efficiency of manual semi-automatic cutting, inability of full-automatic docking type to effectively identify the position of the logo of the raw material belt, and high price of existing devices.

[0005] To solve the above technical problems, the present application provides a control method for identifying elastic band with logo, which comprises:

[0006] Start conveying the raw material belt;

[0007] The color sensor detects whether the length of the raw material belt meets the interval length preset threshold value. If yes, the control unit immediately stops conveying the raw material belt;

[0008] The cutting device cuts off the excess part of the raw material belt and continues to convey the product belt to a preset length and then stops conveying;

[0009] The cutting device cuts the raw material belt to form the product belt and sends the product belt into the sewing device.

[0010] During the conveying of the raw material belt, the length between each level is continuously monitored.

[0011] Optionally, before starting to convey the raw material belt, the color mark sensor is calibrated so that the color mark sensor can distinguish between the marked area and the unmarked area.

[0012] Optionally, before starting to convey the raw material belt, the interval length between the marks of the raw material belt is obtained to determine the starting position of the marks.

[0013] Optionally, the length from the starting point of the mark in the product belt to the cutout is obtained as the position of the color mark sensor.

[0014] Optionally, when the size of the mark of the product belt is too large or the mark is too close to the cutout, the color mark sensor is placed close to the conveying belt.

[0015] Optionally, after the color mark sensor detects the starting position of the mark of the raw material belt, the conveying is stopped after conveying a pre-detection length; the cutting device cuts the raw material belt to form the product belt and sends the product belt into the sewing device; wherein the difference between the length from the end of the position of the color mark sensor away from the cutout to the cutout and the length of the position of the color mark sensor is the pre-detection length value.

[0016] Optionally, one raw material belt corresponds to at least one size of product belt.

[0017] Optionally, when one raw material belt corresponds to two different sizes of product belts, the sum of the lengths of the two different sizes of product belts is equal to the sum of the lengths of two product belts of one size.

[0018] Optionally, when one raw material belt corresponds to two different sizes of product belts, staggered size production is performed, one large size product belt is first produced, and then one small size product belt is produced.

[0019] Optionally, the detection method for staggered size production of product belts includes:

[0020] The length of the position of the color mark sensor of the large size product belt is measured as the placement position of the color mark sensor.

[0021] A large size product belt is first produced.

[0022] Then, when producing a small size product belt, after detecting the starting position of the mark of the raw material belt, the large size minus the half of the size difference is conveyed.

[0023] A small size product belt is then produced.

[0024] Compared with the prior art, the present application has the following advantages:

[0025] In the control method for identifying the identification rubber band provided by the present application, when the color mark sensor detects that the length of the raw material band meets the preset threshold of the interval length, the control unit immediately stops the conveying of the raw material band; the cutting device cuts off the excess part of the raw material band and continues to convey the finished product band to a preset length and then stops the conveying; the cutting device cuts the raw material band to form the finished product band, and the color mark sensor can efficiently identify the identification position. Further, the control method for identifying the identification rubber band can also produce the raw material band with error codes alternately, thereby saving raw materials. The control method for identifying the identification rubber band can also detect the identification in advance, and is not afraid of the arbitrary position of the identification and the size of the finished product band. The present application uses the color mark sensor, which is small in size and low in price. The use of the color mark sensor makes the whole device simple, flexible and low in cost.

The control method for identifying the identification-containing rubber band will be described in detail below in combination with Figures 1-4

[0045] Please refer to Figure 1 The control method for identifying the identification-containing rubber band provided by the present embodiment comprises the following steps.

[0046] Step S10, calibrating the color sensor.

[0047] In Step S10, the color sensor 13 is calibrated before starting to convey the raw material band, so that the color sensor 13 can distinguish the identification area and the non-identification area of the raw material band.

[0048] Please refer to Figure 2 ​, the raw material belt is provided with a LOGO (mark) area and a non-mark area, the mark area is a LOGO-printed area, and the non-mark area is a blank area; the color mark sensor 13 is calibrated, and the color mark sensor 13 outputs a level change when detecting the LOGO (mark) and the non-LOGO area of the raw material belt; the single-chip microcomputer collects the level change and the angle of rotation of the motor in the level change interval, converts the length of the belt walked according to the parameters of the mechanical device, measures the length between all level changes on the rubber band, takes the length as the basic length data of the LOGO area on the raw material belt, and calculates the position of the light spot of the color mark sensor 13 on the rubber band with the LOGO at any moment in the working state.

[0049] In step S11, the interval length between the marks on the raw material belt is measured to determine the starting position of the mark.

[0050] Please refer to Figure 3 In step S11, the interval length between the marks on the raw material belt is measured to determine the starting position of the mark. As shown in Figure 3 , the length between the adjacent marks on the raw material belt is the interval length.

[0051] In step S12, the length from the starting point of the mark on the finished product belt to the cut is measured to place the color mark sensor,

[0052] Please refer to Figure 4 , A is the cut point, B is the starting point of the mark on the finished product belt, and the length between A and B is the length from the starting point of the mark on the finished product belt to the cut. The cutting device 11 is placed opposite the cut point A to facilitate cutting of the raw material belt; the color mark sensor 13 is placed opposite the length AB from the starting point of the mark on the finished product belt to the cut to facilitate detection of the mark on the raw material belt. The mechanical device 12 is placed between the cutting device 11 and the color mark sensor 13.

[0053] In step S13, the raw material belt is started to be conveyed.

[0054] In step S14, it is detected whether the length conforms to the interval length.

[0055] In step S14, the color mark sensor is used to detect the length of the conveyed raw material belt. If the length of the raw material belt conforms to the interval length, step S15 is performed. If the length of the raw material belt does not conform to the interval length, step S13 is performed.

[0056] In step S15, the conveying is stopped, and the excess part is cut off.

[0057] In step S15, when the color sensor 13 detects that the length of the raw material band meets the preset threshold of the interval length, the control unit immediately stops the conveying of the raw material band, the cutting device cuts off the excess part of the raw material band to prepare for obtaining the next finished product band; in this embodiment, the preset threshold of the interval length is, for example, 70 cm.

[0058] In step S16, the finished product band is conveyed to a preset length.

[0059] In step S16, when the finished product band is conveyed to a preset length, the system simultaneously monitors and records the length value between each level to provide data for the next cutting of the finished product band. In this embodiment, the preset length of the finished product band is, for example, 80 cm.

[0060] In step S17, the conveying of the raw material band is stopped after the finished product band is conveyed to a length, the cutting device 11 cuts the raw material band to form the finished product band, and the finished product band is sent to a sewing device (not shown in the figure).

[0061] In step S17, the conveying of the raw material band is stopped after the finished product band is conveyed to a length, the cutting device 11 cuts the raw material band to form the finished product band, and the finished product band is sent to a sewing device (not shown in the figure).

[0062]

Embodiment Two

[0063] The difference from the first embodiment is that when the size of the LOGO of the raw material band is too large or the distance between the LOGO of the raw material band and the cutting point A is too close, the color sensor 13 cannot be placed between the starting point B and the cutting point A of the mark on the raw material band due to the mechanical device 12, at this time, the color sensor 13 can be placed close to the starting point B of the mark on the raw material band, the difference between the length of the cutting point A and the length of the position of the color sensor 13 away from the cutting point A is used as the pre-detection length value, and after the color sensor 13 detects the position of the starting point B of the LOGO of the raw material band, the pre-detection length is conveyed, which is the pre-detection function of the color sensor 13, and realizes that the LOGO of the raw material band can be effectively positioned at any position.

[0064] Figure 5 is the pre-detection flowchart of the control method for identifying the elastic rubber band with a mark according to the second embodiment of the present application;

[0065] Figure 6 is the position diagram of the color sensor and the finished product band in the pre-detection flowchart according to the second embodiment of the present application; the pre-detection method of the control method for identifying the elastic rubber band with a mark will be described in detail below. Figures 5-6

[0066] The present embodiment provides a pre-detection method for identifying the elastic rubber band with a mark, which comprises the following steps:

[0067] In step S20, the raw material band is conveyed.

[0068] ​Step S21, detecting whether the length is in accordance with the interval length.

[0069] In step S21, the color sensor 13 is used to detect the length of the conveyed raw material tape. If the detected length of the raw material tape is in accordance with the interval length, step S22 is executed. If the detected length of the raw material tape is not in accordance with the interval length, step S20 is executed.

[0070] Step S22, conveying the detected length in advance.

[0071] Please refer to Figure 6 When the identification size of the finished product tape is too large or the distance between the identification starting point B of the raw material tape and the cutting point A is too close, the color sensor 13 cannot be placed due to the mechanical device 12 placed between the cutting device 11 and the color sensor 13, and the color sensor 13 is placed close to the starting point B of the raw material tape.

[0072] In step S22, after the color sensor 13 detects the identification starting point B of the raw material tape, the detected length in advance is conveyed. The value of the detected length in advance is the length from the end of the color sensor 13 away from the cutting point A minus the length of the color sensor 13.

[0073] Step S23, stopping conveying and cutting off the excess part.

[0074] In step S23, when the color sensor 13 detects that the length of the raw material tape is in accordance with the preset threshold value of the interval length, the control unit immediately stops the conveying of the raw material tape, and the cutting device cuts off the excess part of the raw material tape to prepare for the next finished product tape. In this embodiment, the preset threshold value of the interval length is, for example, 70 cm.

[0075] Step S24, conveying the length of the finished product tape.

[0076] In step S24, when conveying the preset length of the finished product tape, the system simultaneously monitors and records the length value between each level to provide data for the next cutting of the finished product tape. In this embodiment, the preset length of the finished product tape is, for example, 80 cm.

[0077] Step S25, stopping conveying, cutting, and feeding into sewing.

[0078] In step S25, after conveying the length of the finished product tape, the conveying of the raw material tape is stopped, the cutting device 11 cuts the raw material tape to form the finished product tape, and the finished product tape is fed into the sewing device.

[0079]

Embodiment Three

[0080] The difference between the embodiment one is that, generally, each raw material belt is used to make a specific size of finished product belt, and some factories use one raw material belt to make several groups of finished product belts with different two size codes, for example, the raw material belt with 82CM cycle, the most economical and suitable finished product belt is 80CM, and it can also be made into the following combinations: 84CM+76CM, 88CM+72CM. When the size code finished product belt is combined, it needs to be produced in error code, that is, first make a large code finished product belt, and then make a small code finished product belt. The raw material belt LOGO detection method in the error code production method is: measure the color mark sensor position length of the large code finished product belt as the placement position of the color mark sensor, first produce a large code finished product belt according to the normal steps, when the next one is produced, after detecting the LOGO starting position, the large code is reduced by half of the code length difference, and then a small code finished product belt is produced according to the normal steps, and the work is cycled to realize the error code production.

[0081] Figure 7 The error code production detection flow chart of the rubber band with logo in the embodiment three of the application is shown in the figure; Figure 8 The position map of the color mark sensor and the finished product belt in the error code production detection flow chart of the embodiment three of the application is shown in the figure; the error code detection method of the rubber band with logo will be introduced in detail below. Figures 7-8 The error code detection method of the rubber band with logo will be introduced in detail below.

[0082] The error code detection method of the rubber band with logo provided by the embodiment includes:

[0083] Step S30, conveying the raw material belt.

[0084] Step S31, detecting whether the length conforms to the interval length.

[0085] In step S31, the color mark sensor 13 is used to detect the length of the conveyed raw material belt, if the length of the raw material belt conforms to the interval length, step S32 is executed. If the length of the raw material belt does not conform to the interval length, step S30 is executed.

[0086] Step S32, stopping conveying and cutting off the excess part.

[0087] In step S32, when the color mark sensor 13 detects that the length of the raw material belt conforms to the interval length preset threshold value, the control unit immediately stops the conveying of the raw material belt, and the cutting device cuts off the excess part of the raw material belt to prepare for the next finished product belt.

[0088] Step S33, conveying the length of the large code finished product belt.

[0089] Please refer to Figure 8A raw material tape corresponds to at least one size of finished tape. In this embodiment, a raw material tape corresponds to two different sizes of finished tape. When a raw material tape corresponds to two different sizes of finished tape, the sum of the lengths of the two different sizes of finished tape is equal to the sum of the lengths of two sizes of finished tape. As shown in Figure 8 the preset length of a finished tape is, for example, 80 cm, and in the case of size error production, one large size finished tape and one small size finished tape can be produced, the preset length of one large size finished tape is, for example, 84 cm, and the preset length of one small size finished tape is, for example, 76 cm; or the preset length of one large size finished tape is, for example, 88 cm, and the preset length of one small size finished tape is, for example, 72 cm; in specific implementation, a plurality of combinations of large size finished tapes and small size finished tapes can be designed, which are not limited herein.

[0090] In step S33, when the raw material tape is conveyed by the preset length of the large size finished tape, the system simultaneously monitors and records the length value between each level to provide data for the next cutting of the small size finished tape.

[0091] In step S34, the conveying is stopped, the cutting is taken, the sewing is sent in, and the large size finished tape is completed.

[0092] In step S34, after the raw material tape is conveyed by the length of the large size finished tape, the cutting device 11 cuts the raw material tape to form the large size finished tape, and the large size finished tape is sent to the sewing device.

[0093] In step S35, the raw material tape is conveyed.

[0094] In step S36, it is detected whether the length conforms to the interval length.

[0095] In step S36, the color mark sensor 13 is used to detect the length of the conveyed raw material tape, and if the length of the raw material tape conforms to the interval length, step S37 is executed. If the length of the raw material tape does not conform to the interval length, step S36 is executed.

[0096] In step S37, half of the length difference between the large size finished tape and the small size finished tape is input.

[0097] In step S38, the conveying is stopped, and the excess part is cut off.

[0098] In step S38, when the color mark sensor 13 detects that the length of the raw material tape conforms to the preset threshold of the interval length, the control unit immediately stops the conveying of the raw material tape, and the cutting device cuts off the excess part of the raw material tape to prepare for the next finished tape.

[0099] In step S39, the small size finished tape is conveyed by the length.

[0100] In step S39, when the small code finished product belt is conveyed by a preset length, the system monitors and records the length value between each level at the same time, so as to provide data for the next cutting of the large code finished product belt.

[0101] In step S40, the conveying is stopped, the cutting is taken, the small code finished product belt is sent into the sewing, and the small code finished product belt is completed.

[0102] In step S40, the conveying of the small code finished product belt is stopped after the length of the small code finished product belt is conveyed, the cutting device 11 cuts the raw material belt to form the small code finished product belt, and the small code finished product belt is sent into the sewing device.

[0103] As can be seen from the above, in the control method for identifying the identification rubber band provided by the application, when the color sensor detects that the length of the raw material belt meets the preset threshold of the interval length, the control unit immediately stops the conveying of the raw material belt; the cutting device cuts off the excess part of the raw material belt, and continues to convey the finished product belt by a preset length and then stops the conveying; the cutting device cuts the raw material belt to form the finished product belt, and the color sensor can efficiently identify the identification position. Further, the control method for identifying the identification rubber band can also produce the wrong code alternately to save the raw material. The control method for identifying the identification rubber band can detect the identification in advance, and is not afraid of the arbitrary position of the identification and the size of the finished product belt. The application uses the color sensor, which is small in size and low in price. The use of the color sensor makes the whole device simple, flexible and low in cost.

[0104] It should be noted that the embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts of each embodiment can be referred to each other. In addition, the different parts of each embodiment can also be used together, and the application does not limit this.
