Description

Technical Field

[0001] This utility model relates to the field of auxiliary tooling technology for cigarette packaging machines, specifically a tooling for adjusting the hook cover of a turret crane. Background Technology

[0002] The transfer turret mold box acts as a receiving and lifting device, conveying the formed tobacco packages upwards. The receiving, releasing, and conveying of tobacco packages is achieved by opening and closing the hook covers on both sides of the transfer turret mold box. A tobacco package positioner precisely adjusts the position of the tobacco packages within the transfer turret mold box. After rotating approximately one revolution within the transfer turret, an input pusher conveys the tobacco packages to the drying wheel. During this process, the hook covers on both sides of the transfer turret mold box remain closed to ensure accurate positioning of the tobacco packages. They are then opened in the next step to receive other tobacco packages. The opening and closing of the transfer turret mold box hook covers is achieved through the engagement of a central bakelite cam curve and a bearing on the hook cover swing arm tightly attached to the cam.

[0003] The hook covers on both sides of the transfer turret mold box open or close simultaneously. The bearing on one side directly contacts the bakelite cam and indirectly transmits the motion to the hook cover on the other side through the bearing assembly. The hook cover opens when the elevator feeds the tobacco package into the transfer turret mold box. After the tobacco package is fed in, the hook cover closes to position the tobacco package, and then the transfer turret rotates. After the tobacco package passes through four stations, the input pusher pushes the tobacco package into the drying wheel. During the pushing process, the hook cover remains closed.

[0004] The tightness of the cigarette pack clamping needs to be adjusted and controlled by the degree of closure of the hook cover. In the existing technology, the height of the hook cover from the bottom of the mold box is the thickness of the cigarette pack, so as to achieve a tight conveying state of the cigarette pack. However, it has been found in use that this will cause the cigarette pack to be easily scratched and have poor shape quality when the friction of the label paper changes during the process of pushing it into the drying wheel. The sides of the cigarette pack are also easily pressed with indentations by the hook cover, which will cause defects in the shape of the cigarette pack and reduce the pass rate.

[0005] After long-term practical testing, it was found that adjusting the distance between the hook cover and the bottom plate of the mold box to the thickness of the cigarette pack + 0.3mm resulted in ideal clamping and positioning of the cigarette pack and good shape quality. However, the existing technology for adjusting the height of the hook cover from the bottom of the mold box is very complicated, requiring multiple people to work together, making the operation cumbersome and inconvenient. In the existing technology, to achieve the required height of the cigarette pack thickness + 0.3mm when adjusting the hook cover of the transfer turret, adjustments and measurements are required using shims and feeler gauges. This necessitates repeatedly adjusting the hook cover height before measuring with the feeler gauge, or pressing the feeler gauge against one side of the module and then pressing the hook cover onto the feeler gauge. Both methods are cumbersome and easily deform the precision feeler gauge, leading to low maintenance efficiency. Summary of the Invention

[0006] To address the inconveniences of the existing technology, the inventors have developed and designed a new transfer turret hook cover adjustment fixture that is simple in structure, low in cost, and easy to use. During adjustment, simply place the adjustment fixture into the mold box, press the hook cover against both sides of the fixture, and tighten the screws. This eliminates many cumbersome adjustment steps. In routine inspections, this fixture is used to check the height of the transfer turret hook cover. By pulling the handle, the pressure of the hook cover on the module can be felt, thus verifying whether the height of the hook cover and the mold box base plate meets the requirements. This device greatly simplifies the adjustment of the transfer turret hook cover, shortens maintenance and inspection time, and significantly improves maintenance efficiency.

[0007] Specifically, this utility model is implemented as follows:

[0008] A turret hook cover adjustment fixture, used as an adjustment module for the hook cover in the turret mold box of a Fock packaging machine, includes:

[0009] The module body has a block-shaped structure, and its length and width are adapted to the length and width of the transfer turret module box, so that it can be inserted into the transfer turret module box. The bosses are set horizontally along the length direction at the top of both sides of the module body, forming an inwardly tapering boss edge. The height of the bosses relative to the bottom surface of the module body is not less than the depth of the transfer turret module box. The bosses are used for positioning the hook cover. The handle is set on one end face of the module body for inserting and removing the module body into and out of the transfer turret module box.

[0010] This fixture also includes a bottom magnet, which is installed on the bottom surface of the module body and is used to attract and install the size adjustment iron sheet. The size adjustment iron sheet has a uniform thickness sheet structure, and its length and width dimensions are adapted to the bottom surface of the module body. It can be attracted and attached to the bottom surface of the module body by the bottom magnet. It is used to increase or decrease the overall relative thickness of the module body so as to adjust the relative height of the boss to match the appropriate hook cover closing position height.

[0011] Furthermore, the bottom magnet is a strip structure embedded flush with the surface along the length of the module body, with at least two strips or multiple dots on the bottom surface of the module body; the specification adjustment iron sheet can be stacked and combined in multiple pieces; the bottom magnet is installed in a detachable manner.

[0012] Furthermore, a movable retaining strip is installed at the top edge of the module body. The movable retaining strip is located above the boss and can open and close relative to the top of the module body, and can provide a downward clamping force to restrict the hook cover of the latch on the boss.

[0013] Furthermore, the movable clip has an L-shaped cross-section, with the bent portion located at the top edge of the module body, the side strips extending downwards, the top strip located on the top surface of the module body, and a lifting guide rod installed on the top strip. The movable clip can be vertically raised and lowered relative to the top of the module body. A compression spring is sleeved on the lifting guide rod to support the movable clip as it is compressed downwards.

[0014] Furthermore, the handle consists of a spherical body and a threaded rod, with the spherical body mounted on the end face of the module body via the threaded rod.

[0015] Furthermore, the top edge of the movable card strip is hinged to the top of the module body, and a hinge spring is installed at the hinge to provide a downward pressing force on the side edge of the movable card strip under normal conditions.

[0016] The working principle of this invention is as follows: The adjustment tooling module is inserted into the transfer turret mold box, aligning the boss with the hook cover. The hook cover is manually rotated, causing its edge to sit on the boss. This achieves the function of determining the closed position of the hook cover by the height of the boss. Normally, without installing the bottom magnet and specification adjustment plates, the initial standard height of the boss is based solely on the initial thickness of the tooling module body. Depending on the actual cigarette pack, shims can be added for adjustment. When different adjustment heights are required, different numbers of specification adjustment plates can be attracted by the bottom magnet as shims to increase or decrease the thickness of the module body, thereby adjusting the height of the boss relative to the bottom plate of the mold box. The movable locking bar is located above the boss and can open and close vertically. It provides downward clamping force through a compression spring or hinge spring. This design eliminates the need to continuously press the hook cover by hand during adjustment. During operation, simply open (lift) the movable locking bar, place the hook against the boss, and then release the movable locking bar. Under the action of the spring, it presses down on the hook cover, making it stably rest on the boss. This frees up both hands, allowing for bolt tightness adjustment without continuous pressing. Therefore, one person can easily and flexibly complete the adjustment work.

[0017] The beneficial technical effects of this utility model compared to the prior art are as follows: By using the tooling designed in this utility model, the process of adjusting the height of the hook cover can be greatly simplified. Simply insert the tooling into the mold box and adjust the position of the hook cover by hand or by the movable locking strip, eliminating the tedious steps of repeated measurement and adjustment required by traditional methods. The distance between the hook cover and the bottom plate of the mold box can be easily controlled by the boss on the module body and the specification adjustment iron plate attracted by the bottom magnet, ensuring that an ideal 0.3mm gap can be achieved for different sizes of cigarette packs, increasing its practicality and flexibility, and thus avoiding the problem of scratches or indentations on the surface of the cigarette pack due to excessive clamping. The movable locking strip design can better fix the hook cover, eliminating the need for continuous manual pressing of the hook cover, improving operational convenience and efficiency.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] Example 1: A turret hook cover adjustment fixture is used as an adjustment module for hook cover 3 in the turret mold box 0 of a Fock packaging machine. It mainly consists of two parts: an adjustment module and a handle. The adjustment module is an integrally formed module body 1, with dimensions designed and manufactured according to the dimensions of the turret mold box 0. The handle is an M6 screw with a nylon ball mounted on it. The module body 1 is the main part of this fixture, and its length is basically consistent with the length of the cigarette pack, covering the entire length of the hook cover 3. The height of the two sides is the required adjustment dimension of the hook cover 3, which is the thickness of the cigarette pack + 0.3mm. This allows adjustment by simply pressing the hook cover 3 against the two sides of the module. The width of the central boss 2 is slightly smaller than the distance between the hook covers 3 on both sides of the mold box when closed. This ensures that the height adjustment of the hook cover 3 is not affected and that the module's movement within the mold box is not hindered, facilitating the insertion and removal of the adjustment module. An M6 screw hole is machined in the center of the front of the module for inserting the handle as a handle 4, facilitating insertion and removal of the module body 1. The handle consists of an M6 screw and a nylon ball with internal threads. It is made from recycled workshop waste parts and is used to facilitate the pushing and pulling of tooling into and out of the transfer turret mold box 0.

[0029] The usage process of this tooling is as follows:

[0030] 1. When used for assembly maintenance, manually rotate the bakelite cam so that the corresponding bearing of the hook cover 3 to be adjusted is at the lowest point of the cam. When used for machine adjustment, rotate the machine to make the hook cover 3 to be adjusted fully closed. At this time, the hook covers 3 on both sides of the mold box are closest to the bottom surface of the mold box, which is the adjustment point.

[0031] 2. Loosen the two fixing screws on each side of the hook cover 3.

[0032] 3. Holding the handle, fully insert the adjustment tooling module into the transfer turret mold box 0.

[0033] 4. Move the hook cover 3 in the elongated hole, press its supporting edge onto the steps on both sides of the module, and then tighten the two fixing screws.

[0034] 5. Pull the handle to remove the fixture, and the adjustment is complete.

[0035] 6. When used for equipment inspection, after turning the machine until the hook cover 3 is fully closed, put the fixture into the mold box, and pull the fixture back and forth by the handle. The pressure will be used to determine whether the height of the hook cover 3 meets the requirements.

[0036] The adjustment device for the hook cover 3 of the transfer turret was implemented in the maintenance, calibration, and assembly repair of the FOCKE.FX unit in December 2023, and its effectiveness was investigated and statistically analyzed. According to the comparative analysis of the statistical results: before implementation, adjusting all 20 hook covers 3 of the ten modules of the transfer turret took an average of 40 minutes. After using this tooling, three assembly repairs and two equipment maintenance and calibrations were performed, with an average time of 20 minutes. Maintenance time was reduced by half, and maintenance efficiency was significantly improved.

[0037] Example 2: Based on Example 1, a bottom magnet 5 is installed on the bottom surface of the module body 1 to cooperate with the specification adjustment iron plate 6 to realize the change of the thickness of the module body 1, so as to adjust the height of the boss 2.

[0038] The specification adjustment iron sheet 6 has a uniform and equal thickness sheet structure, and its length and width dimensions are adapted to the bottom surface of the module body 1. The thickness of each sheet is 0.5mm. It can be attracted and attached to the bottom surface of the module body 1 by the bottom magnet 5. It is used to increase or decrease the overall relative thickness of the module body 1 so as to adjust the relative height of the boss 2 to match the appropriate closing position height of the hook cover 3.

[0039] The bottom magnet 5 is a strip structure embedded flush with the surface along the length of the module body 1, with at least two strips or multiple dots on the bottom surface of the module body 1; the specification adjustment iron sheet 6 can be stacked and combined in multiple pieces; the bottom magnet 5 is installed in a detachable manner.

[0040] In use: Set the initial height according to the actual thickness of the tobacco pack being used. Use the bottom magnet 5 to attract different numbers of adjustable iron plates 6 to increase or decrease the thickness of the module body 1, thereby adjusting the height of the boss 2 relative to the bottom plate of the mold box. Gradually adjust the height of the boss 2 to meet the requirement of tobacco pack thickness + 0.3mm.

[0041] Example 3: Based on Example 1 or 2, preferably, a movable retaining strip 11 is also installed at the top edge of the module body 1. The movable retaining strip 11 is located above the boss 2. The movable retaining strip 11 can open and close relative to the top of the module body 1 and can provide a downward clamping force to restrict the hook cover 3 from being fastened on the boss 2. The movable retaining strip 11 can open and close in the vertical direction and provides a downward clamping force through the compression spring 10 or the hinge spring to ensure that the hook cover 3 is stably placed on the boss 2.

[0042] In actual use: First, open the movable retaining strip 11 and place the hook cover 3 on the boss 2. Close or release the movable retaining strip 11 so that its side strip 7 presses down to tighten the hook cover 3, ensuring that the hook cover 3 is stable and does not spring back. This eliminates the need for continuous manual pressing; one person can complete the entire operation.
