Description

Technical Field

[0001] The utility model belongs to the technical field of code sticking equipment, and more specifically, relates to a positive-negative code sticking device. Background Art

[0002] Packaging bags can be used to hold various media. There are various types of packaging bags on the market, including plastic packaging bags, paper packaging bags, paper-plastic composite packaging bags, etc. When the packaging bag contains products for sale, a traceability code is usually affixed to the outer wall of the packaging bag (usually a paper or paper-plastic packaging bag). At the same time, in order to make the products or goods contained in the packaging bag attract customers or increase the sales of the goods, the merchant of the goods will affix a scratch code or a lottery QR code on the inner wall of the packaging bag. The traceability code located on the inside of the packaging bag is defined as a positive code, and the lottery QR code located on the inside of the packaging bag is defined as a negative code. In order to facilitate customers to open the packaging bag for scanning and prevent the negative code from being scanned from the outside of the packaging bag, the positive code and the negative code are usually stacked or overlapped on the packaging bag, that is, from the outside of the packaging bag, the positive code can cover the negative code.

[0003] In the production of packaging bags, the existing technology of the code sticking machine can stick the QR code (whether it is a traceability code or a lottery QR code) on the packaging bag, generally stick it on the bottom seal of the packaging bag, and then seal it. However, one code sticking machine can only stick the code on one packaging bag, and it is not easy to stick the two codes on the inside and outside of the packaging bag at the same time. It can only stick the code on one side first, then turn the packaging bag over, and then use the code sticking machine to stick the code on the other side. This operation method is easy to reduce the efficiency of packaging bag sticking, and it is not easy to implement large-scale packaging bag sticking operations. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Please also read Figure 1 to Figure 2 Now, the Yin-Yang code labeling device provided by the utility model is described. The Yin-Yang code labeling device includes a conveying mechanism 1, a Yin-Yang code labeling machine 2 and a Yang-Yang code labeling machine 3. The conveying mechanism 1 has a conveyor belt 11 for conveying packaging bags that moves in a straight line direction. The conveying speed of the conveyor belt 11 can be adjusted. The bottom seal of the packaging bag 4 is located outside the conveyor belt 11; the Yin-Yang code labeling machine 2 is located above the conveyor belt 11 and is used to label the lottery QR code toward the inner side wall of the bottom seal of the packaging bag 4. The lottery QR code is defined as a Yin code; the Yang-Yang code labeling machine 3 is located below the conveyor and is used to label the traceability code toward the outer side wall of the bottom seal of the packaging bag 4. The traceability code is defined as a Yang code. The labeling direction of the Yin-Yang code labeling machine 2 is set opposite to the labeling direction of the Yang-Yang code labeling machine 3, so that the Yin code and the Yang code are attached to the packaging bag 4 at the same time.

[0028] Compared with the prior art, the positive and negative code labeling device provided by the utility model uses a negative code labeling machine 2 and a positive code labeling machine 3 to label simultaneously, and labels a plurality of packaging bags 4 located on a conveyor belt 11 in sequence, thereby solving the technical problem that it is difficult for the used labeling machine to simultaneously label the negative code and the positive code on the packaging bag 4, resulting in low efficiency of the labeling operation. The utility model has the advantages of being able to label the negative code and the positive code on the packaging bag 4 at the same time, being able to label successfully at one time, improving the efficiency of the labeling operation, and being able to achieve the technical effect of labeling a large number of packaging bags 4.

[0029] The conveying mechanism 1 includes a driving motor, a driving wheel, a driven wheel and a conveyor belt 11 wrapped around the driving wheel and the driven wheel. A frame 12 is connected between the driving wheel and the driven wheel. The conveyor belt 11 has a certain length and width. The power output end of the driving motor is connected to the driving wheel and driven to rotate, and the conveyor belt 11 drives the driven wheel to rotate, thereby realizing the transportation or delivery of the packaging bag 4. By controlling the start and stop of the conveying mechanism 1, the running position of the packaging bag 4 can be controlled. The coordinated operation of the conveying mechanism 1 and the negative code attaching machine 2 and the positive code attaching machine 3 can realize the simultaneous attachment of the positive and negative codes (negative code and positive code) on the packaging bag 4, thereby improving the operation efficiency and speed of the code attachment. The negative code attaching machine 2 and the positive code attaching machine 3 in this embodiment both adopt the code attaching machine in the prior art, and the types of codes attached on the two code attaching machines are pre-set, such as the lottery QR code is set to be attached on the negative code attaching machine 2, and the traceability code is set to be attached on the positive code attaching machine 3. Both the negative code attaching machine 2 and the negative code attaching machine 2 have an attaching end, and both the attaching ends have the freedom to extend and lift vertically. The attaching end of the negative code attaching machine 2 runs downward, and the attaching end of the positive code attaching machine 3 runs upward. After each attaching the code, it retracts and returns to its original position before attaching the code to the next packaging bag 4. In this embodiment, after attaching the code once, the conveyor belt 11 moves a certain distance. The two cooperate with each other to realize the simultaneous attaching of codes to the packaging bags 4 on the conveyor belt 11 in sequence.

[0030] To achieve control of the operation of the negative code attaching machine 2 and the positive code attaching machine 3, in some embodiments, refer to Figures 1 to 4 The yin-yang code sticking device also includes a control panel 5, which is electrically connected to the conveying mechanism 1, the yin-yang code sticking machine 2 and the yang-yang code sticking machine 3 and controls the operation respectively. The control panel 5 has control buttons suitable for controlling the operation of the conveying mechanism 1, the yin-yang code sticking machine 2 and the yang-yang code sticking machine 3 respectively. There are multiple control buttons on the control panel 5, which can realize the control of the operation of the yin-yang code sticking. By operating the control panel 5, the movement or shutdown of the packaging bag 4 can be controlled, and the sticking of the yin-yang code can also be controlled, which is conducive to the realization of automatic sticking operation. In this embodiment, the control panel 5 adopts the product in the prior art, which includes a PLC controller, a control circuit and a control button, etc., and the sticking operation of the yin-yang code can be realized through manipulation.

[0031] In some embodiments, see Figures 1 to 4, the negative code attaching machine 2 and / or the positive code attaching machine 3 are connected with a sensor 6, which is suitable for sensing the position of the packaging bag 4. The sensor 6 is electrically connected to the control panel 5 and sends a position signal of the packaging bag 4 to the control panel 5. When the control panel 5 senses that the packaging bag 4 is located below the negative code attaching machine 2 (which can be defined as a preset position), or when the packaging bag 4 is located above the positive code attaching machine 3 (which can be defined as a preset position), the control panel 5 controls the conveying mechanism 1 to stop operating, and simultaneously controls the negative code attaching machine 2 and the positive code attaching machine 3 to operate, so as to attach the negative code and the positive code to the packaging bag 4 at the same time. When the packaging bag 4 moves to the preset position, the control panel 5 controls the conveying mechanism 1 to stop operating, and simultaneously controls the negative code attaching machine 2 and the positive code attaching machine 3 to operate simultaneously, so that the inner and outer side walls of the bottom surface of the packaging bag 4 (which is a part of the structure of the packaging bag 4) before the bottom of the packaging bag 4 is sealed can be subjected to the coding operation, thereby realizing the automatic control operation of the coding operation of the packaging bag 4. Since the negative code attaching machine 2 and the positive code attaching machine 3 are operated simultaneously, the bottom surface of the packaging bag 4 can be prevented from being folded or bent, and the positive and negative codes are attached to the same position on the packaging bag 4 at the same time.

[0032] In order to enable the negative code attaching machine 2 and the positive code attaching machine 3 to attach codes in other directions, in some embodiments, refer to Figures 1 to 4 , the Yin-Yang code pasting device also includes a Yin-Yang code rotating table 7 and a Yang-Yang code rotating table 8. The Yin-Yang code rotating table 7 has a rotating end that rotates circumferentially in a vertical plane. The Yin-Yang code pasting machine 2 is connected to the rotating end of the Yin-Yang code rotating table 7, and the Yang-Yang code pasting machine 3 is connected to the rotating end of the Yang-Yang code rotating table 8. Each of them rotates circumferentially in a vertical plane with the help of the rotating end, so that the Yin-Yang code pasting machine 2 and the Yang-Yang code pasting machine 3 face different positions or directions for pasting codes. In this embodiment, the Yin-Yang code rotating table 7 and the Yang-Yang code rotating table 8 both adopt the electric rotating table in the prior art, and have the above-mentioned rotating end. The Yin-Yang code rotating table 7 and the Yang-Yang code rotating table 8 are connected to the end of the rotating end. By controlling the rotation angle or direction of the rotating end, the pasting position or direction of the two pasting machines can be adjusted, and then the bottom surface of the packaging bag 4 in different states (referring to the state where the angle between the bottom surface of the packaging bag 4 and the horizontal plane is uncertain) can be used for pasting codes. As Figure 4 When the angle between the plane where the bottom surface of the packaging bag 4 is located and the horizontal plane is an acute angle or an obtuse angle, the utility model can also realize the operation of simultaneously affixing codes. Figure 2 As shown in the figure, the bottom surface of the packaging bag 4 is arranged in the horizontal plane or parallel to the horizontal plane, so that the labeling direction of the two labeling machines (labeling machines) is along the vertical direction. Figure 4 When the bottom surface of the packaging bag 4 is in the state shown in FIG. 1 , the coding direction of the coding machine is set in an inclined shape or at a certain angle to the vertical direction.

[0033] To achieve control of the two rotating stages, in some embodiments, refer to Figures 1 to 4The negative code rotating platform 7 and the positive code rotating platform 8 are electrically connected to the control panel 5. The control panel 5 has a rotating button suitable for controlling the operation of the negative code rotating platform 7 and the positive code rotating platform 8 respectively. The rotating button is used to control the rotation angle of the rotating end. By turning the rotating button on the control panel 5, the angular direction and angle of the rotating end can be controlled, and then the position or direction of the code on the packaging bag 4 can be controlled. The operation is relatively flexible and convenient to use.

[0034] In order to realize that the female code rotating platform 7 and the male code rotating platform 8 can be placed in a suitable position for operation, in some embodiments, refer to Figures 1 to 4 The Yin-Yang code attaching device also includes a support frame 9, and the Yin-Yang code rotating platform 7 and the Yang-Yang code rotating platform 8 can be detachably connected to the support frame 9. The height of the support frame 9 can be adjusted, thereby adjusting the operating height of the Yin-Yang code attaching machine 2 or the Yang-Yang code attaching machine 3. Figure 4 As shown in the figure, the upper and lower parts of the support frame 9 are respectively provided with horizontal slide rails 91, and the negative code rotating table 7 and the positive code rotating table 8 are both connected with vertical vertical rods 92, and the lower end or the upper end of the vertical rod 92 is slidably connected to the horizontal slide rails 91, so that the horizontal position of the negative code rotating table 7 and the positive code rotating table 8 can be adjusted, and then through the rotation of the rotating end, the two labeling machines can realize the simultaneous labeling operation on the bottom surfaces of the packaging bag 4 in different states.

[0035] Preferably, two sets of retaining frames 93 are provided on the support frame 9, and the two sets of retaining frames 93 are used to place and support the negative code attaching machine 2 and the positive code attaching machine 3. When the negative code attaching machine 2 and the positive code attaching machine 3 are not working, the attaching ends of the negative code attaching machine 2 and the positive code attaching machine 3 can be placed on the retaining frames 93, so that when the support frame 9 is transported, the negative code attaching machine 2 and the positive code attaching machine 3 can be kept still or motionless to avoid movement or activity and damage. The retaining frame 93 is provided with a hook 95 for hanging the negative code attaching machine 2 and the positive code attaching machine 3.

[0036] To facilitate the free movement of the support frame 9 or movement in any direction, in some embodiments, refer to Figures 1 to 4 The bottom of the support frame 9 is provided with a plurality of universal wheels 94, and the universal wheels 94 are used to support the movement of the support frame 9. The universal wheels 94 are generally arranged in four, and are products of the prior art.

[0037] In some embodiments, see Figures 1 to 4 At least one universal wheel 94 is connected with a brake or a lock (which is prior art and not shown in the figure), and the brake or the lock is used to lock or brake the universal wheel 94. The brake and the lock also adopt prior art products, which are used to brake the travel wheel, thereby preventing the support frame 9 from moving.

[0038] In some embodiments, see Figures 1 to 4A lifting platform 10 is provided at the bottom of the conveying mechanism 1. The lifting platform 10 has the freedom of vertical lifting and is used to adjust the height of the conveying mechanism 1, and then adjust the height of the labeling of the packaging bag 4. The lifting platform 10 is a lifting column in the prior art, which can be manually controlled or electrically controlled. The lifting and lowering adjustment of the conveying mechanism 1 can be achieved through control. Specifically, the top of the lifting platform 10 is connected to the middle of the bottom end of the frame 12, so that the height of the packaging bag 4 can be adjusted, which is convenient for the labeling machine to perform the labeling operation.
