Technical Field
[0001] This utility model relates to the field of strapping technology, and in particular to a strapping identification, replacement and rejection device. Background Technology
[0002] The main functions of packing straps are to bundle goods, prevent them from scattering during transportation, and improve the appearance and efficiency of packaging.
[0003] Existing packing machines require over 2800 binding operations per shift in actual production. However, due to factors such as raw material availability, delays in replacing packing straps, and the machine's design, missed bindings are common, affecting the product binding pass rate. Taking a capacity of 6.5 tons per hour, with each box of finished explosives weighing 24 kg as an example, approximately 4.6 boxes are produced per minute. If employees are not vigilant within 5 minutes, about 23 boxes of unpacked finished products will enter the warehouse with the delivery truck. This causes significant inconvenience for subsequent manual repacking. Therefore, there is an urgent need for a packing strap identification and repacking rejection device capable of repacking missing straps in finished explosive boxes, reducing the need for subsequent manual repacking. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a strapping tape identification and re-attaching device that can re-attach missing strapping tape to finished explosive boxes, thereby reducing the need for subsequent manual re-attaching.

[0036] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0037] Please refer to Figures 1 to 4 A cable tie identification, replacement, and rejection device, comprising:
[0038] The first conveyor belt 1 has a first photoelectric switch 11 and a first color mark sensor 12 arranged sequentially at its end along the conveying direction;
[0039] The second conveyor belt 2 has its starting end located at the end of the first conveyor belt 1;
[0040] The third conveyor belt 3 has its starting end located at the end of the second conveyor belt 2;
[0041] The strapping device 4 is connected between the end of the second conveyor belt 2 and the beginning of the third conveyor belt 3;
[0042] The second photoelectric switch 21 is located on one side of the second conveyor belt 2;
[0043] The third photoelectric switch 31 is located on one side of the third conveyor belt 3, and the third photoelectric switch 31 and the second photoelectric switch 21 are symmetrically arranged on both sides of the binding device 4.
[0044] The fourth conveyor belt 5 has its starting end located at the end of the third conveyor belt 3. The end of the fourth conveyor belt 5 is provided with a fourth photoelectric switch 51 and a second color mark sensor 52 in sequence along the conveying direction.
[0045] The fifth conveyor belt 6 has its starting end located at the end of the fourth conveyor belt 5, and the fifth conveyor belt 6 is perpendicular to the fourth conveyor belt 5.
[0046] Weighing machine 7 is located at the beginning of the fifth conveyor belt 6;
[0047] The rejection device 8 is connected to the beginning of the fifth conveyor belt 6. The rejection device 8 is used to reject finished explosive boxes 10 that do not meet the weight standard and have missing binding straps.
[0048] In the above embodiments, it should be noted that the first color mark sensor must be installed below the first conveyor belt roller to avoid the influence of the carton height on the recognition. Secondly, it should be installed at a position slightly to the left or right, not in the middle to avoid the influence of tape reflection on the recognition. The second color mark sensor is on the side. The advantage of this setting is that the second color mark sensor can improve the redundancy of the equipment. The recognition positions of the first and second color mark sensors are different, which can improve the recognition accuracy. The strapping device 4 is Yongchuang MH 102B, and the weighing machine 7 is Jin Aobo weighing machine. The second photoelectric switch is a falling edge from on to off, and the third photoelectric switch is a rising edge from off to on.
[0049] When the finished explosive box 10 is conveyed from the beginning to the end of the first conveyor belt 1, the first photoelectric switch 11 senses the finished explosive box 10, and its light remains on. The first color mark sensor 12 senses the color of the strapping tape of the finished explosive box 10. When it senses the color, the light on the first color mark sensor 12 flashes briefly, and the sensing time is recorded. Simultaneously, the time it takes for the finished explosive box 10 to completely pass through the first photoelectric switch 11 is recorded. Assuming the time to complete passing through the first photoelectric switch 11 is 1 second, and the two strapping tapes of the finished explosive box 10 are located on either side of the center of the finished explosive box 10, the time to reach the center of the finished explosive box 10 can be calculated as 0.5 seconds. When the light on the first color mark sensor 12 flashes only briefly, it is recorded as 1 second. At this point, the time it takes for the first color mark sensor 12 to flash once is recorded. Since the first and second straps of the finished explosive box are symmetrically arranged on both sides of the center of the finished explosive box, if the recording time is greater than 0.5 seconds, it can be determined that the first strap 101 of the finished explosive box 10 was missed; if the recording time is less than 0.5 seconds, it can be determined that the second strap 102 of the finished explosive box 10 was missed. If the light of the first color mark sensor 12 flashes twice and is recorded as 2, it can be determined that the finished explosive box 10 was not missed. If the light of the first color mark sensor 12 does not flash and is recorded as 0, it can be determined that the finished explosive box 10 was missed. When the record is 1 or 0, when re-attaching the first strap 101 of the finished explosive box 10, as shown in the attached... Figure 1 As described above, the finished explosive box 10 needs to pass through the second conveyor belt 2 and the third conveyor belt 3. When the third photoelectric switch 31 changes from off to on, the second and third conveyor belts 2 and 3 stop conveying, and the first binding strap 101 of the finished explosive box 10 is re-attached. When the second photoelectric switch 21 changes from on to off, since the first binding strap 101 was previously identified as missing, the controller can block the signal from the second photoelectric switch 21 changing from on to off, meaning the second binding strap 102 will not be packaged. When it is necessary to re-attach the second binding strap 102 of the finished explosive box 10, as shown in the attached... Figure 2As shown, the finished explosive box 10 needs to pass through the second conveyor belt 2 and the third conveyor belt 3. When the second photoelectric switch 21 goes from on to off, the second conveyor belt 2 and the third conveyor belt 3 stop conveying and re-attach the second binding strap 102 of the finished explosive box 10. The signal of the third photoelectric switch 31 going from off to on is blocked. When the finished explosive box 10 has no missed attachments, when the record is 2, the second conveyor belt 2 and the third conveyor belt 3 do not stop. The controller blocks the signals of the second photoelectric switch 21 going from on to off and the third photoelectric switch 31 going from off to on. When the binding device 4 malfunctions or re-attachment fails, the second color mark sensor 52 and the fourth photoelectric switch 51 of the fourth conveyor belt 5 determine the missing attachment status of the finished explosive box 10. Then, the finished explosive box 10 is conveyed to the beginning of the fifth conveyor belt 6. The weighing machine 7 of the fifth conveyor belt 6 weighs the finished explosive box 10. When the weighing does not meet the standard or the finished explosive box 10 has missed attachments, the system will detect any missing attachments. When a device is established, the rejection device 8 rejects the finished explosive box 10 from the fifth conveyor belt 6. When the weighing reaches the standard and the finished explosive box 10 is not missing, the fifth conveyor belt 6 transports the finished explosive box 10 to the end of the fifth conveyor belt 6. Compared with the prior art, the first color mark sensor 12 and the first photoelectric switch 11 determine the missing situation of the finished explosive box 10. Then, the second photoelectric switch 21 and the third photoelectric switch 31 are used to control the second conveyor belt 2 and the third conveyor belt 3 to stop for re-splitting. Then, the second color mark sensor 52 and the fourth photoelectric switch 51 determine the missing situation of the finished explosive box 10, and the weighing integrated machine 7 determines whether the weighing meets the standard. Thus, unqualified and missing finished explosive boxes 10 can be rejected, the missing packing strap of the finished explosive box 10 can be re-splitting, and the finished explosive box 10 due to the failure of the binding device 4 can be rejected. The packing strap of the finished explosive box 10 meets the standard.
[0050] As an optional implementation, the rejection device 8 includes a gantry frame 81, a first cylinder 82, a fixed plate 83, a second cylinder 84, and a push plate 85. The gantry frame 81 is connected to the side of the fifth conveyor belt 6 near the end of the fourth conveyor belt 5. The first cylinder 82 is connected to the gantry frame 81, with the cylinder body axis of the first cylinder 82 in the vertical direction. The fixed plate 83 is connected to the piston rod of the first cylinder 82. The second cylinder 84 is connected to the fixed plate 83, with the cylinder body axis of the second cylinder 84 parallel to the conveying direction of the fourth conveyor belt 5. The push plate 85 is connected to the piston rod of the second cylinder 84.
[0051] In the above embodiments, when the finished explosive box 10 is missing or the weight of the finished explosive box 10 is not up to standard, the fifth conveyor belt 6 stops conveying, the first cylinder 82 drives the fixing plate 83 to move down, and the second cylinder 84 drives the push plate 85 to push the finished explosive box 10 out onto the fifth conveyor belt 6, thus completing the rejection.
[0052] As an optional implementation, the first conveyor belt 1, the second conveyor belt 2, the third conveyor belt 3 and the fourth conveyor belt 5 are all constructed with conveyor rollers. A support plate 9 is provided between two adjacent rollers of the second conveyor belt 2 and the third conveyor belt 3. The height of the support plate 9 is lower than the height of the conveyor roller.
[0053] In the above embodiments, the finished explosive box 10 can be stably transported to the binding device 4 for binding.
[0054] As an alternative implementation, a sixth conveyor belt 61 is provided on the side of the fifth conveyor belt 6 away from the gantry.
[0055] In the above embodiments, the unqualified finished explosive boxes 10 are removed by setting a sixth conveyor belt 6.
[0056] As an optional implementation, a guide device 13 is provided on the side of the first conveyor belt 1 near the first photoelectric switch 11. The guide device 13 includes two guide plates 131, and the openings of the two guide plates 131 decrease along the conveying direction.
[0057] In the above embodiments, by providing the guiding device 131, the movement of the finished explosive box 10 can be prevented.
