Description

Technical Field

[0001] The utility model relates to the technical field of size measuring equipment, in particular to a carton size measuring device. Background Art

[0002] Carton packaging refers to the packaging of products in paper boxes to protect them, facilitate storage and transportation, and promote sales during their circulation. In response to the call to save resources and strengthen the effective use of cartons, the cutting size accuracy of cartons has attracted much attention. However, since cartons are made up of multiple pieces of cardboard and are generally used, most of them have expanded and deformed. Traditional carton processing measuring tools mainly use centimeter-based rulers to measure the size of the required cartons, which takes a long time and has low work efficiency. The data obtained after measurement is input into the carton cutting device for internal substitution. However, since cartons are made up of multiple pieces of cardboard and have an expansion effect, the measurement error of the tool measured in centimeters and against each other is large. In addition, the length limit of traditional carton measuring tools makes the device length large, which is extremely inconvenient to use. In addition, traditional carton processing measuring tools can only measure the length of a single side at a time. After measurement, the tool needs to be removed and measured again, which is inconvenient to operate. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Please refer to Figures 1 to 4 A carton size measuring device includes a workbench 1, an X-axis photoelectric servo drive mechanism 2, a Y-axis photoelectric servo drive mechanism 3, and a Z-axis photoelectric servo drive mechanism 4. The workbench 1 has a detection area 11 for placing cartons, and the X-axis photoelectric servo drive mechanism 2, the Y-axis photoelectric servo drive mechanism 3, and the Z-axis photoelectric servo drive mechanism 4 are all located in the detection area 11.

[0028] The workbench 1 includes a crossbeam 101 and a longitudinal beam 102;

[0029] The X-axis photoelectric servo drive mechanism 2 is slidably connected to the crossbeam 101 , and the X-axis photoelectric servo drive mechanism 2 can move back and forth along the length direction of the X-axis coordinate of the detection area 11 ;

[0030] The Y-axis photoelectric servo drive mechanism 3 is arranged opposite to the X-axis photoelectric servo drive mechanism 2. The Y-axis photoelectric servo drive mechanism 3 is located at the lower end of the X-axis photoelectric servo drive mechanism 2. The Y-axis photoelectric servo drive mechanism 3 can move back and forth along the length direction of the Y-axis coordinate of the detection area 11;

[0031] The Z-axis photoelectric servo drive mechanism 4 is connected to the longitudinal beam 102 , and the Z-axis photoelectric servo drive mechanism 4 moves back and forth in the longitudinal direction of the Z-axis coordinate of the detection area 11 .

[0032] In this technical solution, an X-axis photoelectric servo drive mechanism 2, a Y-axis photoelectric servo drive mechanism 3 and a Z-axis photoelectric servo drive mechanism 4 are installed in the workbench 1. The X-axis photoelectric servo drive mechanism 2 is used to detect the length dimension of the target carton, the Y-axis photoelectric servo drive mechanism 3 is used to detect the width dimension of the target carton, and the Z-axis photoelectric servo drive mechanism 4 is used to detect the height dimension of the target carton. The target carton is measured by the X-axis photoelectric servo drive mechanism 2, the Y-axis photoelectric servo drive mechanism 3 and the Z-axis photoelectric servo drive mechanism 4, and there is no need to measure the length of a single side and then measure it again. When the target carton arrives at the detection area 11 of the workbench 1, the Y-axis photoelectric servo drive mechanism 3 positions the target carton, and then measures the width of the target carton, the X-axis photoelectric servo drive mechanism 2 measures the length of the target carton, and the Z-axis photoelectric servo drive mechanism 4 measures the height of the target carton.

The first detection plate 23 is installed on one side of the movable longitudinal beam 24, and the first detection plate 23 faces the detection area 11; the first screw 22 is fixedly installed on the other side of the movable longitudinal beam 24, and the first screw 22 is connected to the X-axis servo motor 21. The X-axis servo motor 21 drives the first screw 22 to drive the first detection plate 23 to move. The X-axis photoelectric servo drive mechanism 2 of this technical solution is used to detect the length size of the target carton. The first detection plate 23 detects that the target carton is already in the detection area, and then the X-axis servo motor 21 is started, driving the first screw 22 to rotate, driving the first detection plate 23 to move according to the length of the target carton, so as to achieve the measurement of the length size of the target carton. The entire detection is not stuck, and the first detection plate 23 can automatically move and measure according to the length size of the target carton. It is suitable for the length size of cartons of different models. The entire measurement is fully automatic and has high measurement accuracy.

[0034] Furthermore, the specific assembly relationship between the first screw rod 22, the movable longitudinal beam 24 and the cross beam 101 is as follows: Figure 1 and Figure 2 As shown, the front and rear ends of the workbench 1 are respectively provided with the crossbeam 101, and the crossbeam 101 is a slide rail.

The structure is stable, and the first screw rod 22 and the movable longitudinal beam 24 can move along the length direction of the length measuring roller 26 and the crossbeam 101, so that the X-axis photoelectric servo drive mechanism 2 can reciprocate back and forth along the length direction of the X-axis coordinate of the detection area 11.

[0035] The specific implementation of the Y-axis photoelectric servo drive mechanism 3 is as follows: Figure 3 As shown, the Y-axis photoelectric servo drive mechanism 3 includes a width measuring sensing cylinder 31, a Y-axis servo motor 32, a second screw rod 33, a transmission positioning part 34 and a movable horizontal detection plate 35.

The Y-axis photoelectric servo drive mechanism 3 of the present technical solution is used to detect the width size of the target carton. The movable horizontal detection plate 35 is located at the lower end of the beam 101. When the target carton enters the detection area 11, the width measuring sensing cylinder 31 senses that the target carton has arrived, and drives the movable horizontal detection plate 35 to move toward the target carton. The Y-axis servo motor 32 is started, driving the second screw rod 33 to rotate. Since the second screw rod 33 is connected to the transmission positioning part 34, when the movable horizontal detection plate 35 moves to the target carton, the length of the transmission positioning part 34 is equal to the width of the target carton. The entire measurement is fully automatic and accurate. Among them, the transmission positioning part 35 includes a transmission belt and gears located on the left and right sides of the transmission belt. The gears are connected to the second screw rod 33. When the second screw rod rotates, it drives the left and right gears to rotate, thereby driving the transmission belt to rotate.

In this technical solution, the height measuring plate 43 detects the target carton, and the lifting cylinder 42 moves along the height direction of the Z-axis coordinate to detect the height of the target carton. The slide rod 41 assists the lifting cylinder 42 in connecting to the height measuring plate 43. Preferably, the height measuring plate 43 is provided with two slide rods 41, which are respectively located on both sides of the lifting cylinder 42, so as to provide a stable structure.
