Description

Technical Field

[0001] The utility model belongs to the technical field of cigarette package detection, and in particular relates to a device for detecting four-sided aluminum foil papers in a small package channel. Background Art

[0002] When the tobacco packaging equipment is in operation, the main packaging equipment packs the cigarettes into small packages, which then enter the auxiliary packaging equipment through the outer conveyor belt of the cigarette packages. The aluminum foil is conveyed through the aluminum foil conveying channel and the folding device is used to wrap the cigarette packages with transparent paper. When the aluminum foil conveying channel or the folding device fails, the aluminum foil will be missing or damaged, so it is necessary to detect the integrity of the aluminum foil of the cigarette packages.

[0003] At present, inductive detection units are generally used for detection. During the transmission of cigarette packages, the cigarette packages pass through the inductive detection units, and the integrity of the aluminum foil of the cigarette packages is judged by the continuity of the detection signal.

[0004] When detecting missing aluminum foil on cigarette packages, since one side of the cigarette package is in contact with the conveyor belt, it is impossible to perform a full inspection on all four sides of the cigarette package, which can easily lead to missed inspections. Utility Model Content

[0005] The purpose of the utility model is to provide a device for detecting aluminum foil on four sides of a small packet channel, so as to solve the technical problem that when detecting the missing aluminum foil of a cigarette packet, since one side of the cigarette packet is in contact with a transmission belt, all four sides of the cigarette packet cannot be detected, and missed detection may occur easily.

[0006] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0007] A device for detecting aluminum foil on four sides of a small packet channel comprises a fixed seat installed between two peripheral conveyor belts, the fixed seat is symmetrically provided with two groups of side conveyor belts for clamping the sides of a cigarette packet and driving the cigarette packet to move between the two peripheral conveyor belts, the fixed seat is fixedly connected with a bottom surface detection unit between the two groups of side conveyor belts, the fixed seat is fixedly connected with a top surface detection unit above the bottom surface detection unit, the fixed seat is provided with side surface detection units on the sides of the two groups of side conveyor belts, and when the cigarette packet is detected, the top surface detection unit, the bottom surface detection unit and the two side surface detection units are respectively aligned with the four sides of the cigarette packet.

[0008] It is further defined that the side transmission belt includes two O-shaped belts and two O-shaped pulleys, the two O-shaped pulleys are rotatably mounted on a fixed seat, the two O-shaped belts are parallelly wound around the two O-shaped pulleys, a driving motor is mounted on the fixed seat, and the output shaft of the driving motor is drivingly connected to one of the O-shaped pulleys. With such a structural design, the two O-shaped belts are in contact with the side of the cigarette pack, and the O-shaped belts on both sides push the cigarette pack. Since there is a gap between the two O-shaped belts, it is convenient for the side detection unit to detect the side of the cigarette pack through the gap.

[0009] It is further defined that the fixing seat includes a plate body, two support blocks are fixedly connected to the plate body, a steel wire is fixedly connected between the two support blocks, and the bottom surface detection unit is located below the steel wire. Such a structural design, by providing a steel wire to support the cigarette pack, makes the shielded surface of the bottom of the cigarette pack smaller, which is convenient for installing the bottom surface detection unit.

[0010] It is further defined that the plate body is fixedly connected with a side plate in the O-shaped belt, and the side detection unit is installed on the side plate. Such a structural design, by arranging the side plate in the O-shaped belt, enables the side detection unit to be installed in the O-shaped belt, thus saving placement space and having strong practicality.

[0011] It is further defined that one of the side panels is fixedly connected to a top panel, and the top surface detection unit is installed on the top panel. Such a structural design forms an L-shaped panel through the side panel and the top panel to complete the installation of the top surface detection unit, which can save the use of materials and has strong practicality.

[0012] It is further defined that the top surface detection unit, the side surface detection unit and the bottom surface detection unit all include an inductive proximity switch and a synchronous detection optical fiber. With such a structural design, the aluminum foil is detected by the inductive proximity switch, and whether the aluminum foil is missing is determined by whether the signal is continuous.

[0013] The utility model adopting the above technical solution has the following advantages:

[0014] 1. Through the cooperation of the peripheral conveyor belt, the side conveyor belt and multiple detection units, the side conveyor belt is connected to the peripheral conveyor belt to expose the bottom surface of the cigarette package, so that the cigarette package passes through multiple detection units and the four sides of the cigarette package are detected respectively, which is not easy to miss the detection.

[0015] 2. The two O-shaped belts are in contact with the sides of the cigarette pack, and the O-shaped belts on both sides push the cigarette pack. Since there is a gap between the two O-shaped belts, it is convenient to install the side detection unit.

[0016] 3. By setting up steel wire to support the cigarette package, the blocked surface of the bottom of the cigarette package is smaller, which is convenient for installing the bottom surface detection unit. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figures 1 to 3 As shown, a four-sided aluminum foil detection device for a small packet channel of the utility model comprises a fixed seat 3 installed between two peripheral conveyor belts 2, two groups of side conveyor belts 4 for clamping the side surfaces of a cigarette package 1 and driving the cigarette package 1 to move between the two peripheral conveyor belts 2 are symmetrically arranged on the fixed seat 3, a bottom surface detection unit 51 is fixedly connected between the two groups of side conveyor belts 4 on the fixed seat 3, a top surface detection unit 52 is fixedly connected above the bottom surface detection unit 51 on the fixed seat 3, and side surface detection units 53 are arranged on the sides of the two groups of side conveyor belts 4 on the fixed seat 3. When the cigarette package 1 is detected, the top surface detection unit 52, the bottom surface detection unit 51 and the two side surface detection units 53 are respectively aligned with the four surfaces of the cigarette package 1.

[0029] As Figure 2 and Figure 3 shown, the side conveyor belt 4 includes two O-shaped belts 41 and two O-shaped belt pulleys 42. The two O-shaped belt pulleys 42 are rotatably installed on the fixed seat 3. The two O-shaped belts 41 are both wound around the two O-shaped belt pulleys 42 in parallel. A driving motor 43 is installed on the fixed seat 3, and the output shaft of the driving motor 43 is in transmission connection with one of the O-shaped belt pulleys 42. In fact, according to the actual situation, a belt with a width dimension smaller than the height dimension of the cigarette packet 1 can also be directly used to clamp the cigarette packet 1. In this embodiment, the two O-shaped belts 41 are in contact with the side surface of the cigarette packet 1, and the two O-shaped belts 41 on both sides push the cigarette packet 1. Since there is a gap between the two O-shaped belts 41, it is convenient for the side detection unit 53 to detect the side surface of the cigarette packet 1 through the gap.

[0030] The fixed seat 3 includes a plate body 31. Two support blocks 32 are fixedly connected to the plate body 31. A steel wire 33 is fixedly connected between the two support blocks 32. The bottom surface detection unit 51 is located below the steel wire 33. In fact, according to the actual situation, a vertical steel bar can also be arranged on the fixed seat 3 between the two groups of side conveyor belts 4 along the length direction of the side conveyor belt 4 to support the cigarette packet 1. In this embodiment, the cigarette packet 1 is supported by arranging the steel wire 33, so that the blocked surface at the bottom of the cigarette packet 1 is smaller, which is convenient for installing the bottom surface detection unit 51.

[0031] The plate body 31 is fixedly connected with a side plate 34 inside the O-shaped belt 41. The side surface detection unit 53 is installed on the side plate 34. In fact, according to the actual situation, a side plate 34 for installing the side surface detection unit 53 can also be directly arranged outside the side conveyor belt 4. In this embodiment, by arranging the side plate 34 inside the O-shaped belt 41, the side surface detection unit 53 is installed inside the O-shaped belt 41, saving the placement space and having strong practicability.

[0032] One of the side plates 34 is fixedly connected with a top plate 35. The top surface detection unit 52 is installed on the top plate 35. In fact, a U-shaped mounting plate spanning the two groups of side conveyor belts 44 can also be directly arranged on the fixed seat 3, and the U-shaped mounting plate provides an installation position for the top surface detection unit 52. In this embodiment, the side plate 34 and the top plate 35 form an L-shaped plate to complete the installation of the top surface detection unit 52, which can save the use of materials and has strong practicability.

[0033] The top surface detection unit 52, the side surface detection unit 53 and the bottom surface detection unit 51 all include an inductive proximity switch and a synchronous detection optical fiber. The aluminum foil paper is detected by the inductive proximity switch, and whether the aluminum foil paper is missing is judged by whether the signal is continuous.

[0034] The usage method and principle of this embodiment are as follows:

[0035] The cigarette package 1 is first transmitted to the top of the steel wire 33 through the peripheral conveyor belt 2 at the front end. Under the transmission of the O-shaped belts 41 on both sides, the cigarette package 1 moves horizontally along the steel wire 33 and is transmitted to the peripheral conveyor belt 2 at the rear end. During the transmission process, when the cigarette package 1 passes through the synchronous detection optical fiber, the synchronization signal is transmitted to the single-chip microcomputer to determine that a cigarette package has passed. The four inductive proximity switches detect the switch signal, and the switch signal is transmitted to the single-chip microcomputer until the cigarette package 1 completely passes through the inductive proximity switch. The single-chip microcomputer determines that when a signal is missing on any side, it is judged as a defective cigarette package 1, and the subsequent rejection device is controlled to reject it.

[0036] The above is a detailed introduction to a four-sided aluminum foil detection device for a small package channel provided by the utility model. The description of the specific embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, several improvements and modifications can be made to the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
