Description

Technical Field

[0001] The utility model relates to the technical field of paper-plastic gluing, in particular to a material mixing prevention device for a paper-plastic automatic gluing machine. Background Art

[0002] The existing glue spraying equipment is equipped with one person for each glue spraying machine. The glue spraying machine is set to a double station. The glue spraying process is as follows: the operator takes the product from the assembly line, places the product on the positioning fixture, presses the start button, and the transfer platform drives the positioning fixture into the glue spraying station. After the glue spraying is completed, the transfer platform returns to the waiting position, and the products after glue spraying are manually taken down and placed on the assembly line, and flow to the full inspection station.

[0003] However, during the operation of existing equipment, personnel need to operate the two workstations of the glue spraying machine at the same time, and constantly repeat the actions of taking and placing products. It is easy to miss the triggering start button. Products that have not been sprayed with glue flow into the next process for assembly and then flow into the client, causing customer complaints. The appearance of different types of glue spraying products is slightly different, which can easily cause wrong materials to be mixed. Mixing can be detected by cameras, but the production cost is high. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides an anti-mixing device for an automatic paper-plastic glue dispensing machine, which solves the problems raised in the above-mentioned background technology.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a paper-plastic automatic glue dispensing machine anti-mixing device, including a glue dispensing machine assembly and an upper stand fixedly mounted on a table plate, the glue dispensing machine assembly including a glue dispensing base, a horizontal slide is installed on the upper rear portion of the glue dispensing base, a glue dispensing main machine is installed in front of the horizontal slide, a longitudinal slide is installed above the glue dispensing base, a color detection assembly is installed in front of both sides of the glue dispensing base, the color detection assembly includes a protective cover, a thin steel plate is installed inside the protective cover, a color code photoelectric switch is installed on the side of the thin steel plate close to the longitudinal slide, a laser displacement sensor is installed on the glue dispensing base close to the rear of the longitudinal slide, a safety grating is installed in front of the upper and lower parts of the upper stand, and a counter is hung in front of the top wall of the upper stand.

[0008] Preferably, the dispensing machine assembly is provided with two dispensing stations, and the number of safety gratings is two sets, which are respectively installed in front of each dispensing station. When a worker reaches into the dispensing station, a signal that the safety grating is blocked will be triggered.

[0009] Preferably, the paper-plastic product is placed on a longitudinal slide and moves forward and backward through the drive of the longitudinal slide, the glue dispensing host is installed on a transverse slide and moves left and right through the drive of the glue dispensing host, and the glue dispensing head under the glue dispensing host can move up and down through the drive of the glue dispensing host, thereby applying glue to the upper surface of the product according to the set path.

[0010] Preferably, the glue used by the dispensing host needs to have a certain color and be different from the color of the product, so that the color detection assembly can detect whether the product has been glued.

[0011] Preferably, there are several color-coded photoelectric switches installed on independent thin steel plates, and the position of each color-coded photoelectric switch detecting the product is changed by changing the angle of each thin steel plate, so as to accurately determine the type of the product.

[0012] Preferably, a slide plate is provided above the longitudinal slide table, and the laser signal of the laser displacement sensor is irradiated on the edge of the slide plate. The position of the slide plate can be detected by the laser displacement sensor, and a signal for counting the counter is generated by the correlation between the detection result of the laser displacement sensor and the detection result of the color detection assembly and the trigger signal of the safety grating.

[0013] The utility model provides a device for preventing mixing of paper and plastic automatic glue dispensing machine, which has the following beneficial effects:

[0014] 1. The anti-mixing device of the paper and plastic automatic glue dispensing machine can prevent products from leaking glue and improve production efficiency through the coordinated arrangement of the safety grating, the color detection assembly, the laser displacement sensor and the alarm light. After the product is placed on the glue dispensing machine, there is no need for the worker to manually press the switch. As long as the color detection assembly detects that there is no glue-coated product and the safety grating signal is not touched, the glue dispensing machine will automatically glue the product. Since there is no need for the worker to manually press the switch but the glue coating work is automatically performed, the time for pressing the switch can be reduced to improve efficiency. At the same time, it can also avoid the occurrence of glue leakage caused by missing the switch. After the un-glued product is placed on the glue dispensing machine, the machine will automatically execute according to the program and will be monitored by the safety grating, the color detection assembly and the laser displacement sensor at the same time. During this process, if there is an abnormal signal, the alarm light will alarm and stop the machine, thereby avoiding the occurrence of product glue leakage caused by misoperation.

[0015] 2. The anti-mixing device of the paper and plastic automatic glue dispensing machine, through the coordinated setting of the color detection assembly, the laser displacement sensor, the safety grating and the counter, enables the anti-mixing device of the paper and plastic automatic glue dispensing machine to effectively count the amount of glue applied on the product in order to check whether there is any wrong material, mixed material or leakage. A counter that displays the amount of glue applied is installed in a conspicuous position, and the counting result of the counter can avoid under-recording or over-recording through the joint control of the color detection assembly, the laser displacement sensor and the safety grating. By comparing the counting result of the counter with the incoming product of the turnover vehicle, it is easy to check whether there is any wrong material, mixed material or leakage.

[0016] 3. The anti-mixing device of the paper and plastic automatic glue dispensing machine has the effect of distinguishing whether there is mixing and low production cost through the setting of the color detection assembly. All products that need to be glued are compared in color, and then different color areas of different products are detected through multiple color-coded photoelectric switches inside the color detection assembly. The detection results fed back by multiple color-coded photoelectric switches can be used to determine which product it is. Since the color-coded photoelectric switch is cheap, its implementation method has low cost. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] See also Figures 1 to 4The utility model provides a technical solution: a paper and plastic automatic glue dispensing machine anti-mixing device, comprising a glue dispensing machine assembly 1 and an upper stand 2 fixedly mounted on a table, the glue dispensing machine assembly 1 comprising a glue dispensing base 101, a horizontal slide 102 is mounted on the upper rear of the glue dispensing base 101, a glue dispensing host 103 is mounted in front of the horizontal slide 102, a longitudinal slide 104 is mounted above the glue dispensing base 101, the paper and plastic product is placed on the longitudinal slide 104 and moves forward and backward through the drive of the longitudinal slide 104, and the glue dispensing host 103 is mounted on the horizontal slide 10 2 and can move left and right through the drive of the dispensing host 103. The dispensing head below the dispensing host 103 can move up and down through the drive of the dispensing host 103, so that the upper surface of the product can be coated with glue according to the set path. The front of both sides of the dispensing base 101 is equipped with a color detection assembly 3. The glue used by the dispensing host 103 needs to have a certain color and be different from the color of the product. Then, the color detection assembly 3 can detect whether the product has been coated with glue. The color detection assembly 3 includes a protective cover 301, and a thin steel plate is installed inside the protective cover 301. 302, a color-coded photoelectric switch 303 is installed on the side of the thin steel plate 302 close to the longitudinal slide 104, and the number of color-coded photoelectric switches 303 is several and installed on each independent thin steel plate 302. By changing the angle of each thin steel plate 302 to change the position of each color-coded photoelectric switch 303 to detect the product, the type of the product can be accurately determined. A laser displacement sensor 4 is installed at the rear of the dispensing base 101 close to the longitudinal slide 104, and a safety grating 5 is installed in front of the upper and lower sides of the upper stage 2. The dispensing machine assembly 1 is provided with two dispensing stations. There are two sets of safety gratings 5 ​​which are installed in front of each dispensing station respectively. When a worker reaches into the dispensing station, a signal that the safety grating 5 is blocked will be triggered. A counter 6 is hung in front of the top wall of the upper stage 2. A slide plate is arranged above the longitudinal slide 104. The laser signal of the laser displacement sensor 4 is irradiated on the edge of the slide plate. The position of the slide plate can be detected by the laser displacement sensor 4. The detection result of the laser displacement sensor 4 and the detection result of the color detection assembly 3 are correlated with the trigger signal of the safety grating 5 to give a counting signal to the counter 6.

[0024] When in use, first dye the glue into a color different from all product color areas according to the distribution of all product color areas and the positions where glue is required, then design and manufacture the color detection assembly 3 according to the distribution of all product color areas and the color of glue. Specifically, the color mark photoelectric switch 303 inside the color detection assembly 3 is fixed with a thin steel plate 302, and then the shape of the thin steel plate 302 is bent so that the signal of the color mark photoelectric switch 303 detects different color images of the product through different angles. It is required that the signal combination detected by multiple color mark photoelectric switches 303 for each product is different, and the signal combination detected before and after glue coating of the same product is also different. How many color mark photoelectric switches 303 are needed to distinguish all products and before and after glue coating? The difference depends on the actual situation. The glue dispensing machine operator stands in the middle of the device and grabs the un-glueized product from the incoming material cart and puts it on the slide on the longitudinal slide 104. When the worker's hand enters the detection range of the safety grating 5, the color detection assembly 3 immediately works, that is, the color mark photoelectric switch 303 starts to detect the color in front. If the color mark photoelectric switch 303 detects the color of the longitudinal slide 104 itself, it is judged that the worker is putting the product on the longitudinal slide 104. At this time, the glue dispensing machine assembly 1 starts to re-execute the glue application procedure. When the signal blocked by the safety grating 5 is restored, it is judged that the worker's hand has left the device. Further, the color detection assembly 3 works again to check each color area of ​​the product through multiple color mark photoelectric switches 303. The color sequence detected by the color-coded photoelectric switch 303 determines the type of product. If it cannot be identified or the product is detected to have been glued, the glue dispensing machine assembly 1 stops the next step and alarms through the alarm light 7. If a product without glue is identified, the glue dispensing machine assembly 1 sends the product to the bottom of the glue dispensing host 103 through the longitudinal slide 104 for gluing. During this process, the laser displacement sensor 4 continuously detects the position of the slide on the longitudinal slide 104 and compares it with the set distance. If the value detected by the laser displacement sensor 4 during the gluing process of the glue dispensing host 103 is different from the set value, it is determined that the glue dispensing machine assembly 1 has a fault and alarms through the alarm light 7. If everything is normal and the gluing program runs smoothly to the end, the color detection assembly 3 starts working again. If the color If the result detected by the color detection assembly 3 is the result that should be detected after the product is glued, it is judged that the gluing is successful and enters the waiting process. The worker then takes out the glued product by hand. During this process, the signal of the safety grating 5 is blocked and then restored. When the detection signal of the safety grating 5 is restored, the color detection assembly 3 checks again. If the result of the inspection is the original color of the longitudinal slide 104, it is judged that the gluing is completed and has been taken out. At this time, the count of the counter 6 is increased by one. If the triggering sequence of the signals in the above process is different, the alarm light 7 will alarm immediately. The above signal detection results and the triggering sequence can ensure accurate counting and avoid glue leakage. At the same time, the signal blocking of the safety grating 5 is used as the start of the glue dispenser assembly 1.It can reduce the time for workers to start manually and thus improve efficiency. Since the glue coating process is logically rigorous and the counting is accurate, it is convenient for workers to check the values ​​of product incoming and outgoing materials, and thus it is convenient to judge whether there is material leakage during the glue coating process. The color code photoelectric switch 303 has low cost and multiple combinations can judge the type of product, thus replacing expensive cameras to reduce costs.

[0025] To sum up, the paper-plastic automatic glue dispensing machine anti-mixing device does not require workers to manually press the switch after placing the product on the glue dispensing machine. As long as the color detection assembly 3 detects that there is no product coated with glue and the safety grating 5 signal is not touched, the glue dispensing machine will automatically coat the product with glue. Since there is no need for workers to manually press the switch but the gluing work is automatically performed, the time for pressing the switch can be reduced to improve efficiency, and the occurrence of glue leakage due to missed pressing of the switch can also be avoided. After the uncoated product is placed on the glue dispensing machine, the machine will automatically execute according to the program and will be monitored by the safety grating 5, the color detection assembly 3 and the laser displacement sensor 4 at the same time. During this process, if there is an abnormal signal, the alarm light 7 will alarm and stop the machine, thereby avoiding misoperation and causing In case of glue leakage on a product, a counter 6 displaying the amount of glue coating is installed in a conspicuous position, and the counting result of the counter 6 can be controlled jointly by the color detection assembly 3, the laser displacement sensor 4 and the safety grating 5 to avoid under-recording or over-recording. By comparing the counting result of the counter 6 with the incoming products of the turnover vehicle, it is easy to check whether there are wrong materials, mixed materials and leaked materials. The colors of all products that need glue dispensing are compared, and then the different color areas of different products are detected by the multiple color-coded photoelectric switches 303 inside the color detection assembly 3. The detection results fed back by the multiple color-coded photoelectric switches 303 can be used to determine which product it is. Since the color-coded photoelectric switches 303 are cheap, the implementation method thereof is low-cost.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
