Description

Technical Field

[0001] This invention relates to the field of cigarette packaging production line equipment technology, and in particular to a device for detecting the removal of desiccant from cigarette packaging boxes and its usage method. Background Technology

[0002] During the cigarette packaging process, cigarettes are packaged on a production line, transferring small packs of cigarettes into cartons. In actual production, the cartons used to package these small packs are stored with a desiccant to keep them dry. When packaging the cigarettes, the carton needs to be opened and the desiccant removed.

[0003] The existing operation involves manually opening the carton, removing the desiccant, and then placing the carton on the production line for packaging into smaller cigarette packs. This manual desiccant removal method is characterized by high labor costs, low efficiency, and a significant risk of desiccant leakage. Summary of the Invention

[0004] The purpose of this invention is to provide a desiccant removal and detection device for cigarette packaging boxes and its usage method, which can automatically remove and detect the desiccant in the carton, avoiding the risk of missed removal.

[0005] According to one objective of the present invention, the present invention provides a device for detecting the removal of desiccant from cigarette packaging boxes, comprising:

[0006] A desiccant suction device is used to suck out the desiccant from the empty desiccant box;

[0007] A detection device is located behind the desiccant absorption device and is used to detect the desiccant in the empty desiccant box.

[0008] Furthermore, the desiccant absorption device includes:

[0009] The horizontally movable seat is fixedly installed on the frame of the cigarette packaging equipment;

[0010] A vertical moving frame is fixedly installed at one end of the horizontal moving base and can move horizontally back and forth with the horizontal moving base.

[0011] The suction nozzle is fixedly installed at the bottom of the vertical moving frame and can move up and down with the vertical moving frame. The top of the suction nozzle is connected to the negative pressure tube.

[0012] Furthermore, the nozzle has a rectangular structure, and the width of the nozzle is smaller than the width of the inner frame of the box, while the width of the nozzle is larger than the width of the desiccant.

[0013] Furthermore, the detection device includes:

[0014] A vertically movable seat is fixed on the frame of the cigarette packaging equipment;

[0015] A horizontally movable frame is fixed to the bottom end of the vertically movable base and can move up and down with the vertically movable base;

[0016] The detector is fixed at one end of the horizontal moving frame and can move back and forth in the horizontal direction with the horizontal moving frame.

[0017] Furthermore, the detector includes a pressure sensor and a pressure plate, the top of which is connected to the horizontal moving frame, and the pressure sensor is disposed between the pressure plate and the horizontal moving frame.

[0018] Furthermore, the width of the detector is smaller than the width of the inner frame of the box, and the width of the detector is larger than the width of the desiccant.

[0019] According to another objective of the present invention, the present invention provides a method for using a desiccant removal detection device for cigarette packaging boxes, comprising the following steps:

[0020] S1, Desiccant absorption

[0021] When the empty carton reaches the horizontal conveyor stop position, during the pause of the empty carton, the desiccant suction device extends into the empty carton to suction the desiccant;

[0022] S2, Desiccant Detection

[0023] After the desiccant is absorbed by the desiccant absorption device, the empty carton moves mechanically. When the empty carton reaches another horizontal conveyor stop position, during the pause of the empty carton, the detection device extends into the empty carton to detect the desiccant.

[0024] Furthermore, S1 specifically includes the following steps:

[0025] S101, when the empty carton reaches the horizontal conveyor stop position, during the period when the empty carton is stationary, the vertical moving frame moves downward and the suction nozzle is inserted into the empty carton containing the desiccant;

[0026] S102, when the suction nozzle reaches the bottom of the inner frame of the empty strip box, the negative pressure tube is connected to the negative pressure, and at the same time the horizontal moving seat moves to the right, and the suction nozzle moves horizontally with the horizontal moving frame.

[0027] S103, when the nozzle moves to the rightmost end of the empty carton, the vertical moving frame moves upward back to the initial position, and the horizontal moving seat drives the vertical moving frame and the nozzle to move to the left and return to the initial position, completing one work cycle;

[0028] S104. During this process, the nozzle is connected to negative pressure. When the nozzle approaches the desiccant in the empty desiccant box, it sucks the desiccant out of the empty desiccant box, thus completing the work of removing the desiccant from the empty desiccant box.

[0029] Furthermore, S2 specifically includes the following steps:

[0030] S201, In the initial position, the vertical moving base is in a retracted state, and the horizontal moving frame located at the bottom of the vertical moving base is also in a retracted state;

[0031] S202, when the empty carton reaches the horizontal conveyor stop position, during the pause of the empty carton, the vertical moving seat moves downward and the horizontal moving frame descends accordingly, so that the detector is inserted into the empty carton containing the desiccant.

[0032] S203, the horizontal moving frame extends and drives the detector to move horizontally from the left end to the right end of the empty carton. When the detector moves to the rightmost end of the carton, the vertical moving seat retracts upward, driving the horizontal moving frame to move upward so that the detector leaves the empty carton. At this time, the horizontal moving frame retracts to the initial position, completing one working cycle.

[0033] S204. During this process, when the detector approaches the desiccant in the empty box, it detects the desiccant present in the empty box, thus completing the detection of the presence of the desiccant in the box.

[0034] Furthermore, it also includes S205, where the detector is triggered by the desiccant when it moves inside the empty carton, issuing an alarm and causing the packaging equipment to stop.

[0035] The technical solution of this invention involves installing a desiccant extraction device at the carton station of a cigarette packaging production line. During the pause in the lateral conveying of empty cartons, the desiccant can be extracted from the carton. The extracted carton then continues on the production line to package the cigarette packs. A detection device can be used to inspect the empty cartons after passing through the desiccant extraction device, promptly detecting any remaining desiccant inside. Attached Figure Description

[0043] Example 1

[0044] like Figures 1-2 As shown,

[0045] A desiccant removal detection device for cigarette packaging boxes includes a desiccant suction device and a detection device, wherein the detection device is located behind the desiccant suction device, wherein:

[0046] The desiccant absorption device includes a horizontal moving base 1, a vertical moving frame 2, and a suction nozzle 3. The horizontal moving base 1 is installed on the frame of the cigarette packaging equipment and can move back and forth in the horizontal direction.

[0047] The vertical moving frame 2 is fixedly installed at one end of the horizontal moving base 1, and the vertical moving frame 2 can move horizontally back and forth with the horizontal moving base 1.

[0048] The suction nozzle 3 is fixedly installed at the bottom of the vertical moving frame 2 and can move up and down reciprocally with the vertical moving frame 2;

[0049] The nozzle 3 is a rectangular square tube. The top of the nozzle 3 is connected to the negative pressure tube 4. The width of the nozzle 3 is slightly smaller than the width of the inner frame of the desiccant box. The width of the nozzle 3 is significantly larger than the width of the desiccant 6. The nozzle 3 can be inserted into or removed from the empty desiccant box 5 when it moves up and down with the vertical moving frame 2.

[0050] When the desiccant suction device starts working:

[0051] In the initial state, the horizontal moving seat 1 is located at the leftmost end;

[0052] When the empty carton 5 reaches the horizontal conveying stop position, during the pause of the empty carton 5, the vertical moving frame 2 moves downward and the suction nozzle 3 is inserted into the empty carton 5 containing the desiccant 6;

[0053] When the suction nozzle 3 reaches the bottom of the inner frame of the carton, the negative pressure tube 4 is connected to the negative pressure, and at the same time the horizontal moving seat 1 moves to the right. The suction nozzle 3 moves horizontally with the horizontal moving frame 8, and the endpoint of the movement is the other end of the empty carton 5.

[0054] When the nozzle 3 moves to the rightmost end of the carton, the vertical moving frame 2 moves upward back to its initial position, and the horizontal moving seat 1 drives the vertical moving frame 2 and the nozzle 3 to move to the left and return to their initial positions, completing one work cycle.

[0055] During this process, since the suction nozzle 3 is connected to negative pressure, when the suction nozzle 3 approaches the desiccant 6 in the empty strip box 5, it can suck the desiccant 6 out of the empty strip box 5, thus completing the work of removing the desiccant 6 from the empty strip box 5.

[0056] In this embodiment, the horizontal moving seat 1 and the vertical moving frame 2 are linear reciprocating motion devices. They can be hydraulically or pneumatically driven or have an electric telescopic rod structure. These are commonly used linear reciprocating motion devices in the field, and can be selected as needed. Their specific structure and shape will not be described in detail here.

[0057] This invention involves installing a desiccant extraction device at the carton station of a cigarette packaging production line. During the time when the empty carton 5 is paused during its lateral conveying, the desiccant 6 can be extracted from the carton. The extracted carton then continues its journey on the production line to package individual cigarette packs.

[0058] The width of the rectangular suction nozzle 3 of the desiccant suction device is smaller than the internal width of the carton and larger than the width of the desiccant 6. The desiccant suction device is set on the carton conveyor line. During the conveying of the carton along the production line, the desiccant suction device can extend into the carton to suck out the desiccant 6 inside the carton. After sucking out the desiccant 6, the rectangular suction nozzle 3 rises and leaves the carton to enter the next suction cycle.

[0059] The detection device includes a vertical moving base 7, a horizontal moving frame 8, and a detector. The vertical moving base 7 is fixed on the frame of the cigarette packaging equipment and can make vertical reciprocating linear motion.

[0060] The horizontal moving frame 8 is fixedly installed at the bottom of the vertical moving base 7 and can move up and down with the vertical moving base 7. The horizontal moving frame 8 can extend and retract in the horizontal direction.

[0061] The detector is fixedly installed at one end of the horizontal moving frame 8 and can move back and forth in the horizontal direction with the horizontal moving frame 8.

[0062] The detector of this invention can move up and down and horizontally with the cooperation of the vertical moving base 7 and the horizontal moving frame 8, which makes it convenient for the detector to be inserted into the empty strip box 5 and move horizontally in the strip box to detect the desiccant 6.

[0063] The detector of this invention is a combination of a lever-type mechanical mechanism and a detection element. Specifically, the detector includes a pressure sensor and a pressure plate 9. The top of the pressure plate 9 is connected to a horizontal moving frame 8, and a pressure sensor is provided between the pressure plate 9 and the horizontal moving frame 8. Under the action of gravity, the pressure plate 9 hangs down naturally. When an object obstructs it, the pressure plate 9 swings accordingly. The pressure sensor receives pressure through the swing of the pressure plate 9, thereby determining whether there is desiccant 6 inside the box. The width of the detector is slightly smaller than the width of the inner frame of the wooden box, and it can be inserted into or removed from an empty box when it moves vertically and up and down.

[0064] When the detection device starts working:

[0065] In the initial position, the vertical moving base 7 is in a retracted state, and the horizontal moving frame 8 located at the bottom of the vertical moving base 7 is also in a retracted state;

[0066] When the empty carton 5 reaches the horizontal conveying stop position, during the pause of the empty carton 5, the vertical moving seat 7 moves downward and the horizontal moving frame 8 descends accordingly, so that the detector is inserted into the empty carton 5 containing the desiccant 6.

[0067] The horizontal moving frame 8 extends, causing the detector to move horizontally from the left end to the right end of the empty carton 5. The endpoint of the movement is the right edge of the empty carton 5. When the detector moves to the rightmost end of the carton, the vertical moving seat 7 retracts upward, causing the horizontal moving frame 8 to move upward so that the detector leaves the empty carton 5. At this time, the horizontal moving frame 8 retracts to the initial position, completing one working cycle.

[0068] During this process, if the desiccant 6 in the empty box 5 is not removed, when the detector approaches the desiccant 6 in the empty box 5, it can detect the desiccant 6 present in the empty box 5, thus completing the detection of the presence of the desiccant 6 in the box.

[0069] This invention uses a detection device to detect empty carton 5 that has passed through the desiccant absorption device, and to detect any remaining desiccant 6 inside the empty carton 5. The detector is a lever-type mechanical detection device that does not contact the empty carton 5 during operation. It is moved along the length of the carton by a horizontal moving frame 8 to complete the detection. Under normal circumstances, there is no desiccant 6 in the carton and the detector is not triggered. When desiccant 6 is left in the carton, the detector is triggered by the desiccant 6 as it moves inside the carton, thereby detecting the presence of desiccant 6, issuing an alarm, and triggering the packaging equipment to stop.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
