Description

Technical Field

[0001] The present invention relates to the technical field of cigarette packaging machines, and in particular to a defective cigarette pack congestion detection device for a folding turret of an FX2 type hard box packaging machine. Background Art

[0002] In the tobacco packaging industry, the FX2 hard box packaging machine is a highly efficient and automated production equipment that is widely used in the packaging process of various tobacco products. The 703 folding turret of this model is the core component of the packaging process. During one rotation of the 703 folding turret, the small box trademark is folded and formed (see the process flow for details). Figure 1 ), its performance and stability are directly related to the quality of the final product and the efficiency of the production line.

[0003] During production, defective cigarette packs can easily clog the 703 folding turret, especially after the packs, wrapped in liner and frame paper, are fed into the folding turret at station 3 and joined with the label paper. This can cause the cigarettes, liner, and label paper to become jammed together, causing the upper half (from the middle of the pack to the flap, located on the outer circle of the folding turret) or lower half (from the middle to the bottom, located on the inner circle of the folding turret) of the pack to bulge, or even the entire pack to bulge. Therefore, pack integrity inspection is required at station 4 to prevent defective packs from entering subsequent processes.

[0004] However, in the existing FX2 hard box packaging machine, although the No. 4 station of the 703 folding turret is equipped with a defective cigarette pack detection device, which can to a certain extent identify and prevent damaged cigarette packs from entering subsequent stations, there are still many shortcomings in actual application.

[0005] First, the existing mold box inspection device has a limited and unadjustable detection range. Its design focuses solely on detecting damage and congestion at the top end of cigarette packs (i.e., where the flap is located). The inspection range fails to fully cover the entire upper half of the pack, and the lower half is not inspected, leaving damage, congestion, and protrusions in these locations undetected. This results in damaged cigarette packs not being promptly detected during production, leading to the bottom of the pack protruding or popping out of the folding turret mold box, causing blockages in subsequent processes and a series of equipment failures and product quality issues. Due to design flaws in the inspection device, if damaged cigarette packs are not promptly identified and removed, they may enter the gluing channel, causing the flap locator to become stuck, or even knocking off the pusher head of the second pusher belt, causing the 703 trademark clapper board at station 1 to become stuck and dislodged, seriously impacting the normal operation of the production line. Furthermore, if the blockage caused by damaged cigarette packs is not promptly resolved, it may also damage the entire folding turret, increasing maintenance costs and significantly reducing production efficiency. Even if the blockage caused by damaged cigarette packs is minor and the machine is not immediately shut down for processing, they may flow into the 753 small pack transparent paper packaging machine, causing packaging failure, and then there is a risk of unqualified cigarette packs entering the market, which will bring unnecessary economic losses to the company.

[0006] Secondly, the coverage of the detection equipment required for cigarette packages with different production requirements is different, and the equipment may have detection accuracy problems after long-term use, so it is often necessary to debug and adjust according to actual production.

[0007] In addition, the folding guide mechanism at station 4 of the 703 folding turret, which is used to limit and guide the upper corners of the trademark paper, is prone to damage and blockage in the longitudinal direction of the cigarette pack and also requires congestion detection.

[0008] Therefore, considering the actual application of the production line, it is urgent to develop a new type of defective cigarette pack congestion detection device. The adjustment of the coverage range of the detection device at the mold box should be controllable and easy to operate, and can be continuously and accurately adjusted to fully cover all parts of the cigarette pack. The congestion detection at the folding guide mechanism should be accurate and easy to reset to improve the detection accuracy and reliability, eliminate the possibility of damaged cigarette packs flowing into subsequent processes, protect the machine from damage, and ensure production safety, production efficiency and product quality.

[0057] The working principle of the present invention is mainly divided into two parts: the mold box congestion detection and the folding guide congestion detection:

[0058] Congestion detection at the mold box: The detection guide rail mechanism (3) of the device can fully cover the congestion detection requirements of the cigarette pack in the turret mold box (A), wherein the first detection guide rail (32) is responsible for triggering the congestion detection of the upper half of the cigarette pack (i.e., the middle of the cigarette pack to the flip cover position), and the second detection guide rail (36) is responsible for triggering the congestion detection of the lower half of the cigarette pack (i.e., the middle of the cigarette pack to the bottom position).

[0059] According to the structural design of the detection guide rail mechanism (3) and the hand-cranked adjustment mechanism (6) of the present invention, the locking bolt (34) on the waist-shaped hole is loosened, and the crank handle (61) is rotated clockwise or counterclockwise. The screw rod on the extension arm member (33) is driven to move through the transmission of the rotating shaft (62), the first bevel gear (63), and the second bevel gear (64). The extension arm member (33) can then be extended forward or retracted backward, thereby controlling the extension length of the extension arm member (33), and further controlling the detection range of the entire detection guide rail mechanism (3) and making fine adjustments. When the detection range is adjusted to a suitable range, the locking bolt (34) is tightened to fix the detection guide rail mechanism (3).

[0060] During actual use, the extension length of the extension arm member (33) can be continuously adjusted according to production needs and a trial run can be carried out to adjust the detection range of the detection guide rail mechanism (3) to achieve an ideal detection effect; by using another structural design of the hand-cranked adjustment mechanism (6) and another structural design of the extension arm member (33), the change in the detection range per moving unit distance can be recorded according to the scale on the extension arm member (33), thereby formulating a process flow, making the adjustment of the detection range convenient and rapid, and enabling the detection guide rail to be quickly and accurately reset when the position is changed by manual maintenance equipment.

[0061] When a defective cigarette pack passes through the detection guide rail mechanism (3) at station No. 4 and triggers a jam detection, the defective cigarette pack pushes the first detection guide rail (32) or the second detection guide rail (36) of the detection guide rail mechanism (3) upwards, thereby causing the detection guide rail mechanism (3) to be lifted along the connecting shaft (2), and the contact rod mechanism (4) connected thereto is separated from the guide rail jam detection device (5), and the guide rail jam detection device (5) sends a stop signal to the folding turret through the control alarm system to alarm the shutdown.

[0062] Folding guide jam detection: By improving the design of the folding guide mechanism (7), when jam occurs at the folding guide, the folding guide (72) connected to the folding guide seat (71) rotates on the turret base (9) through the rotating shaft (74), so that the contact below the folding guide seat (71) deviates from the folding guide jam detection device (8). The folding guide jam detection device (8) sends a stop signal to the folding turret through the control alarm system to alarm the shutdown. At the same time, the handle member (73) connected to the folding guide (72) is stuck in the waist-shaped groove on the fixed block (76). After the jam is resolved, the handle member (73) is held and removed from the waist-shaped groove on the fixed block (76). Under the action of the rebound member (75), the folding guide mechanism (7) can rebound and reset.

[0063] Beneficial effects of the present invention:

[0064] 1. The present invention significantly improves the adjustability and controllability of the detection range: through the design of a hand-cranked adjustment mechanism, the detection range of the detection device can be easily and labor-savingly adjusted. In addition, since the extension and retraction of the extension arm are driven by a handle and gears, this design allows the extension amount of the extension arm to be very finely controlled and adjusted continuously and precisely, reducing the problem of improper detection range setting due to misoperation.

[0065] By using the gear and scaled rack structure design of the hand-cranked adjustment mechanism, the change in the detection range per unit distance can be recorded according to the scale on the rack, so as to formulate a process flow, making the adjustment of the detection range convenient and fast. When the manual maintenance equipment causes the position of the detection guide rail to change, it can be quickly and accurately reset, further improving the adjustability and controllability of the detection range.

[0066] 2. The present invention enhances the reliability and stability of the equipment: The present invention can accurately sense the congestion of cigarette packs during transmission, ensuring the sensitivity and accuracy of the detection device, thereby timely discovering and processing defective cigarette packs, avoiding unnecessary accumulation and shutdown on the production line, and ensuring the continuous and efficient operation of the production line.

[0067] 3. This invention reduces production costs, improves production efficiency, and improves product quality: Due to the high sensitivity and accuracy of the detection device, defective cigarette packs can be detected and processed promptly, thus avoiding equipment damage and downtime caused by cigarette pack blockage. This not only reduces the number of manual interventions and repair costs, but also improves production efficiency and reduces errors and omissions caused by human factors, significantly improving production efficiency and product quality.

[0068] 4. Easy installation and maintenance: This invention adopts a modular design, with components such as the base, connecting shaft, and detection guide mechanism all detachable and connectable. This not only facilitates installation and commissioning, but also greatly facilitates subsequent maintenance and replacement. If a component fails or requires an upgrade, it can be quickly replaced, reducing maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0090] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments; it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention; in addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0091] Example 1

[0092] This embodiment mainly describes the specific implementation method of the congestion detection at the mold box. All components of this device are prefabricated in the factory. Among them, the detection guide mechanism 3 and the hand-cranked adjustment mechanism 6 are made of ABS plastic to reduce the weight of the device. This makes it easier for the bulge caused by the congestion of cigarettes, liner paper, and trademark paper to lift up the detection guide mechanism, thereby improving the detection sensitivity.

[0093] like Figure 2 — Figure 20 The device for detecting congestion of defective cigarette packs on the folding turret of an FX2 type rigid box packaging machine shown includes a control and alarm system, and further includes:

[0094] A machine base 1, which is detachably connected to the folding turret No. 4 of the packaging machine;

[0095] A connecting shaft 2, wherein the connecting shaft 2 is detachably connected to the base 1;

[0096] A detection guide rail mechanism 3, wherein the detection guide rail mechanism 3 is detachably connected to the connecting shaft 2 and is rotatable on the connecting shaft 2;

[0097] A touch rod mechanism 4, wherein the touch rod mechanism 4 is fixedly connected to the bottom of the detection guide rail mechanism 3;

[0098] A guide rail congestion detection device 5 is detachably connected to the turret base 9 by bolts and is connected to the touch rod mechanism 4. The guide rail congestion detection device 5 is a proximity switch;

[0099] The hand-cranked adjustment mechanism 6 is fixedly connected between the two detection rail arms 31 of the detection rail mechanism 3 .

[0100] The folding guide mechanism 7 is detachably connected to the turret base 9 below the detection guide rail mechanism 3.

[0101] The folding guide congestion detection device 8 is connected to the turret base 9 below one end of the folding guide mechanism 7, and the folding guide congestion detection device 8 is a proximity switch.

[0102] Further, such as Figure 3 — Figure 8 As shown, the detection guide rail mechanism 3 includes:

[0103] Detection guide rail arms 31, there are two detection guide rail arms 31, which are detachably connected to both ends of the connecting shaft 2;

[0104] A first detection guide rail 32 , which is arc-shaped, is located below the detection guide rail arm 31 and is connected to the two guide rail arms 31 ;

[0105] An extension arm member 33 detachably connected to the detection rail arm 31 via a locking bolt 34 passing through a waist-shaped hole;

[0106] Locking bolts 34, which are four in two groups and are used to connect the detection rail arm 31 and the extension arm member 33, and the extension arm member 33 and the connecting column 35 respectively;

[0107] Connecting posts 35 , two of which are detachably connected to the extension arm member 33 via locking bolts 34 passing through the circular holes of the extension arm member 33 ;

[0108] The second detection guide rail 36 is arc-shaped, located below the connecting posts 35 , and connected to the two connecting posts 35 .

[0109] The detection guide rail mechanism 3 of this device can fully cover the congestion detection requirements of the cigarette pack in the turret mold box A, among which the first detection guide rail 32 is responsible for triggering the congestion detection of the upper half of the cigarette pack, that is, the middle of the cigarette pack to the flip position, and the second detection guide rail 36 is responsible for triggering the congestion detection of the lower half of the cigarette pack, that is, the middle of the cigarette pack to the bottom position.

[0110] Specifically, such as Figure 10 As shown, the extension arm member 33 of this embodiment adopts the design structure of the extension arm member 331 with a screw rod. The extension arm member 331 with a screw rod is an "E"-shaped structure as a whole. The two arms at both ends have a waist-shaped hole and a circular hole respectively, and the middle arm is connected to the screw rod;

[0111] Further, such as Figure 15 As shown, the touch rod mechanism 4 includes:

[0112] A touch rod 41, wherein the touch rod 41 is fixedly connected to the bottom of one of the detection guide rail arms 31;

[0113] The contact 42 is fixedly connected below the contact rod 41 .

[0114] Further, such as Figure 3 、 Figure 8 、 Figure 9 As shown, the design structure of the hand-cranked adjustment mechanism 6 adopted in this embodiment includes:

[0115] A crank 61, which is composed of a strip-shaped connecting piece and a cylindrical handle;

[0116] A rotating shaft 62 , one end of which is connected to the connecting member of the crank 61 , and the other end of which is connected to the first bevel gear 63 ;

[0117] A first bevel gear 63, wherein a shaft hole is formed in the middle of the first bevel gear 63, and the shaft 62 is connected to the shaft hole;

[0118] A second helical gear 64 , which meshes with the first helical gear 63 and has a threaded hole in the middle thereof, which meshes with a screw rod of a middle arm of the extension arm member 33 ;

[0119] The gear box 65 is fixedly connected to the connecting platform 66. The gear box 65 is in the shape of a stepped boss, and the first helical gear 63 and the second helical gear 64 are installed inside.

[0120] The connecting platform 66 is fixedly connected between the two detection rail arms 31 of the detection rail mechanism 3 .

[0121] In summary, the specific use process of the present invention is:

[0122] Before starting production, install the device at station 4 of the folding turret of the FX2 hard box packaging machine, ensuring that the first detection guide rail 32 is located in the upper half of the mold box.

[0123] Further, such as Figure 3 、 Figure 4As shown in the figure, the equipment is debugged, the locking bolt 34 on the waist-shaped hole of the extension arm component 331 is loosened, and then the crank handle 61 is rotated clockwise or counterclockwise. The transmission of the rotating shaft 62, the first bevel gear 63, and the second bevel gear 64 drives the screw rod on the extension arm component 33 to move, and the extension arm component 33 can be extended forward or retracted backward, thereby controlling the extension length of the extension arm component 33, and then controlling the detection range of the detection guide mechanism 3 to expand forward, and can be fine-tuned. After adjusting to the appropriate detection range, tighten the locking bolt 34 to fix the detection guide mechanism 3. According to production needs, the extension length of the extension arm component 33 is continuously adjusted and a trial run is carried out to adjust the detection range of the detection guide mechanism 3 until all defective cigarette packs can be detected and no longer flow into the subsequent process.

[0124] Further, such as Figure 5 、 Figure 6 As shown, after achieving the ideal detection effect, the turret equipment is operated. When the defective cigarette pack passes through the detection guide rail mechanism 3 of station 4 and triggers the congestion detection, the defective cigarette pack pushes the first detection guide rail 32 or the second detection guide rail 36 of the detection guide rail mechanism 3 upward, so that the detection guide rail mechanism 3 is lifted along the connecting shaft 2, and the touch rod mechanism 4 connected thereto is separated from the guide rail congestion detection device 5, and the contact is disconnected from the proximity switch. The guide rail congestion detection device 5 sends a stop signal to the folding turret through the control alarm system to alarm the shutdown.

[0125] Finally, if Figure 15 As shown, the operator lifts up the detection guide rail mechanism 3 to take out the damaged cigarette pack, and resets the detection guide rail mechanism 3 after resolving the congestion problem.

[0126] Example 2

[0127] This embodiment mainly describes the specific implementation method of the congestion detection at the mold box. All components of this device are prefabricated in the factory. Among them, the detection guide mechanism 3 and the hand-cranked adjustment mechanism 6 are made of ABS plastic to reduce the weight of the device. This makes it easier for the bulge caused by the congestion of cigarettes, liner paper, and trademark paper to lift up the detection guide mechanism, thereby improving the detection sensitivity.

[0128] The design structure of Example 2 is basically the same as that of Example 1, except that:

[0129] like Figure 14 As shown, the extension arm component 33 of this embodiment adopts an extension arm component 33a with a scale rack. The extension arm component 33a with a scale rack is an "E"-shaped structure as a whole. The two arms at both ends have a waist-shaped hole and a circular hole respectively. One side of the middle arm is a serrated rack and the other side is a length scale.

[0130] Further, such as Figure 11 、 Figure 13As shown, the design structure of the hand-cranked adjustment mechanism 6 adopted in this embodiment includes:

[0131] A handle 6a, the handle 6a consisting of a strip-shaped connecting piece and a cylindrical handle;

[0132] A transmission shaft 6b, one end of which is connected to the connecting piece of the handle 6a, and the other end of which is connected to the transmission gear 6c;

[0133] A transmission gear 6c connected to the transmission shaft 6b;

[0134] The gear rack box 6d is fixedly connected to the connecting seat 6e. The gear rack box 6d has a rectangular bottom and a circular boss on the top, and a transmission gear 6c is installed inside.

[0135] The connecting seat 6e is fixedly connected between the two detection guide rail arms 31 of the detection guide rail mechanism 3.

[0136] Compared with the previous structural design, the structural design of this hand-cranked adjustment mechanism no longer requires helical gears to change the transmission direction, and the structure is more compact and efficient.

[0137] The debugging process is as follows Figure 11 、 Figure 12 As shown, the specific usage process is the same as that of Example 1 and will not be repeated here.

[0138] In this embodiment, the structural design of the gear and the rack with scale of the hand-cranked adjustment mechanism 6 can record the change in the detection range of the moving unit distance according to the scale on the extended arm component 33, so as to formulate a process flow; and in the actual production process, it can be used as an important reference to record the congestion-prone positions, so that the adjustment of the detection range is convenient and rapid, and when the manual maintenance equipment causes the position of the detection guide rail to change, it can be quickly and accurately reset.

[0139] Example 3

[0140] This embodiment mainly describes the specific implementation method of folding guide congestion detection. The design structure of embodiment 3 may be the same as that of embodiment 1 or embodiment 2, wherein the main functional components are the folding guide mechanism 7 and the folding guide congestion detection device 8.

[0141] Specifically, such as Figure 16 — Figure 20 As shown, the folding guide mechanism 7 includes:

[0142] The fold guide seat 71 is detachably connected to the turret base 9 by bolts and can be fine-tuned through the waist-shaped adjustment hole 711 on the fold guide seat 71. A contact for triggering congestion detection is provided below the fold guide seat 71;

[0143] A folding guide 72 , wherein the folding guide 72 is connected to the folding guide seat 71 , and the folding guide 72 can rotate on the turret base 9 via a rotating shaft 74 connected to the bottom of the folding guide seat 71 ;

[0144] a handle member 73 passing through the folding guide 72 and fixedly connected to one end of the folding guide 72;

[0145] A rotating shaft 74, one end of which is connected to the bottom of the folding guide seat 71, and the other end of which is connected to the turret base 9 through a bearing;

[0146] a resilient member 75 connected to the lower portion of the folding guide seat 71;

[0147] The fixing block 76 is detachably connected to the turret base 9 by bolts, and has a waist-shaped groove for fixing the handle component 73 on the fixing block 76.

[0148] Specifically, such as Figure 20 As shown, the resilient member 75 includes:

[0149] A first connecting shaft 751 , the first connecting shaft 751 is connected to the lower side of the folding guide seat 71 ;

[0150] A second connecting shaft 752, the second connecting shaft 752 is connected to the turret base 9;

[0151] The spring 753 has one end connected to the first connecting shaft 751 and the other end connected to the second connecting shaft 752 .

[0152] In summary, the specific use process of the present invention is:

[0153] like Figure 17 、 Figure 18 As shown, before starting production, the device is first installed at the No. 4 station of the folding turret of the FX2 hard box packaging machine, wherein the folding guide mechanism 7 is installed in the empty space below the two detection guide rail arms 31 of the detection guide rail mechanism 3, and fine-tuning is performed through the waist-shaped adjustment hole 711 on the folding guide seat 71 so that the folding guide 72 is parallel to the first detection guide rail 32 and the handle member 73 can be just stuck in the waist-shaped groove on the fixed block 76, and then all bolts are tightened; further, the folding guide congestion detection device 8 is passed through the mounting hole on the turret base 9 and aligned with the contact below the folding guide seat 71 and locked and fixed.

[0154] Further, such as Figure 16As shown, when the turret equipment is running and congestion occurs at the folding guide mechanism 7, the folding guide 72 connected to the folding guide seat 71 rotates on the turret base 9 through the rotating shaft 74, so that the contact under the folding guide seat 71 deviates from the folding guide congestion detection device 8. The folding guide congestion detection device 8 sends a stop signal to the folding turret through the control alarm system to alarm the shutdown. At the same time, the handle component 73 connected to the folding guide 72 is stuck in the waist-shaped groove on the fixed block 76.

[0155] Finally, if Figure 16 As shown, after the operator removes the damaged cigarette pack from the folding guide mechanism 7 to resolve the congestion problem, he grasps the handle member 73 and removes it from the waist-shaped groove on the fixed block 76. Under the action of the rebound member 75, the folding guide mechanism 7 rebounds and resets. After that, the folding turret device can be restarted.

[0156] It should be understood that the above-described specific embodiments of the present invention are merely illustrative or illustrative of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included within the scope of protection of the present invention. In addition, the appended claims are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
