Description

Technical Field

[0001] The invention relates to the field of equipment technology, and in particular to a packaging adjustment method for cigarette strips with or without a strip box and trademark paper. Background Art

[0002] As global environmental problems become increasingly severe, public environmental awareness has significantly increased, and consumers' demand for green and environmentally friendly products is growing. Therefore, the country has timely proposed a "green development" strategy, aiming to achieve harmonious coexistence of economic and social development and ecological environmental protection through technological innovation and industrial upgrading. At present, some cigarette products in the tobacco industry have the problem of excessive packaging in production, which not only increases the production costs of enterprises, but also aggravates resource consumption and environmental pressure, and deviates from the green and low-carbon development concept. For this reason, it is an innovative measure to carry out strip-free box paper packaging on products (directly wrapping transparent paper outside the two-layer five-column cigarette group, eliminating the packaging of strip paper).

[0003] However, in actual production, since the packaging carton paper is omitted, during the packaging and forming process of the cigarette pack group, there are differences in the dimensions of the conveying and folding channels and the dimensions of the cigarette rods without carton paper compared to those with carton paper, resulting in insufficient adaptability of the equipment.

DETAILED DESCRIPTION

[0096] In order to make the objectives, technical solutions and advantages of the present invention clearer, the implementation method of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0097] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0098] The present invention provides a packaging adjustment method for cigarette strips with or without a box label paper in an embodiment. The specific overall adjustment idea is as follows:

[0099] According to the tobacco rod forming process, only the length, width and height of the following four tobacco rod forming channels need to be adjusted accordingly to meet the corresponding tobacco rod size (see Figure 2 ), adjust the program flow as follows Figure 1 shown.

[0100] The selection of adjustment references is as follows: the reference in the direction of cigarette strip length is the left side of the channel in the direction of cigarette strip running, and the position of the right channel is changed to meet the change in the length of the cigarette strip; the reference in the direction of cigarette strip width is the extreme position of the previous cigarette running forward, and the position of the YB95 transparent paper packaging machine is adjusted to meet the change in the width of the cigarette strip; the reference in the direction of cigarette strip height is the bottom surface of the channel in which the cigarette strip runs, and the top surface of the channel is adjusted to meet the change in the height of the cigarette strip. The selection of the above adjustment reference is the core of the method of the present invention, and the subsequent specific adjustment methods are all implemented on the above adjustment reference; it is also the most obvious difference (compared to the equipment manufacturer's modification of product specifications, the geometric center of the cigarette strip is selected as the adjustment reference). The selection of the above reference, taking one side as the reference, and changing the other side to meet the requirements of the size of the cigarette strip, greatly reduces the adjustment workload of the equipment. The conveying and folding channels such as Figure 2 The specific steps include:

[0101] Step S1, adjust the size of the conveying channel of the YB65 carton packaging machine,

[0102] Step S2, adjusting the size of the first lifting channel at the junction of YB65 and YB95,

[0103] Step S3, adjusting the size of the horizontal conveying channel of the YB95 transparent paper packaging machine,

[0104] Step S4, adjusting the size of the second lifting channel of YB95.

[0105] As a preferred embodiment of the present invention, step S1 specifically includes the following steps:

[0106] Step S11, adjustment of the length direction of the cigarette rods in the conveying channel of the YB65 carton paper packaging machine (the length of the cigarette rods changes from 282.5 mm to 280 mm):

[0107] The adjustment reference of the length direction of the cigarette rod is: the distance from the box reference plane 3 is x = 134mm, that is, taking the left side of the cigarette rod conveying direction as the reference, the left rotating angler 1, the left spiral body 2, and the left spiral plate 4 on the left side remain unchanged, and the positions of the right spiral plate 6, the right spiral body 7, and the right spiral angler 8 on the right side are changed to adapt to the length L of the cigarette rod 5, see Figure 3 As shown. The adjustment is based on the left side of the cigarette rod conveying direction, which is 134mm away from the box body, and not based on the center of the cigarette rod, which greatly reduces the amount of channel size adjustment, which is also the core of this technology as an adjustment method. The correct choice of adjustment basis affects the adjustment quality, efficiency and economy.

[0108] According to the size change of the tobacco rod 5, ΔL1=L1-L2=282.5-280=2.5mm;

[0109] Adjust the right spiral turning angle 8 to move left by ΔL=2.5mm; adjust the right spiral body 7 to move left by ΔL=2.5mm; adjust the right spiral plate 6 to move left by 2.5mm. Therefore, when the special right spiral plate 6 is not replaced, it is necessary to make appropriate adjustments to the right spiral plate 6 to ensure that the right spiral plate 6 can move left by 2.5mm.

[0110] Step S12, adjustment of the tobacco strip width direction of the conveying channel of the YB65 carton paper packaging machine (the tobacco strip width dimension changes from 89.5 mm to 88 mm):

[0111] The adjustment reference of the tobacco rod width direction is: the position A when the propeller 9 moves to the front end. That is, when the tobacco rod width dimension X changes, the distance L between YB65 and YB95 is changed by adjusting the connection 11 between the YB65 and YB95 bodies to adapt to the tobacco rod width, see Figure 4 shown.

[0112] When the propeller moves to the frontmost position A, there are 9 cigarettes in the channel, ΔL2=9(X1-X2)=9(89.5-88)=13.5mm, so the requirement of the stripless box paper conveying channel can be met by shortening the connection distance between YB65 and YB95 by ΔL2=13.5mm.

[0113] However, when YB95 approaches the YB65 fuselage, the first lifter 10 will interfere with the left spiral plate 4 and the right spiral plate 6 at B and C. Therefore, if the left spiral plate 4 and the right spiral plate 6 are not replaced, it is necessary to make appropriate improvements to the left spiral plate 4 and the right spiral plate 6 to eliminate the interference. Figure 5 shown.

[0114] Step S13, the height direction of the conveying channel of the YB65 carton packaging machine is adjusted (the height of the cigarette rod is changed from 49 mm to 47 mm):

[0115] The basis for adjusting the height dimension of the YB65 conveying channel is: the bottom plate surface F of the conveying channel, that is, the size of the bottom plate surface F remains unchanged, and the upper cover plate 14 and the upper guide plate 15 can be adjusted to meet the requirements of the height dimension change of the tobacco rod. (See Figure 6 (shown)

[0116] When the height S' of the cigarette rod changes, ΔS'=49-47=2mm

[0117] The height of the top cover Q is adjusted by p in the front, that is, by adjusting p to lower the upper cover 14 by ΔS' = 2mm, the requirements of cigarette strips without box paper can be met;

[0118] When the height S' of the cigarette rod changes, the rear upper guide plate 15 cannot be adjusted in height because it is fixedly installed above the left bracket 13 and the right bracket 12. The height of the left bracket 13 and the right bracket 12 can only be reduced by ΔS'=2mm. When the height of the left bracket 13 and the right bracket 12 changes, the height of the left spiral plate 4 and the right spiral plate 6 should also be reduced by ΔS'=2mm to ensure that the upper guide plate 15 is reduced by ΔS'=2mm. Therefore, if the special parts (left spiral plate 4, right spiral plate 6 and left bracket 13 and right bracket 12) are not replaced, the dimensions of the left spiral plate 4, right spiral plate 6 and the left bracket 13 and the right bracket 12 must be adjusted in the height direction to meet the requirements of the cigarette rod without box paper.

[0119] Conclusion: The adjustment of the conveying channel of the YB65 carton paper packaging machine in the three directions of length, width and height requires appropriate modification of the dimensions of the four special parts, namely the left spiral plate 4, the right spiral plate 6, the left bracket 13 and the right bracket 12, in order to meet the requirements of conveying cigarette strips without carton paper. There are two main technical solutions for these four special parts: Solution 1, the cigarette machine factory redesigns the parts according to the actual dimensions of the cigarette strips; Solution 2, based on the existing conditions, the factory designs the parts on its own, taking into account the production of cigarette strips with carton paper, so as to achieve rapid switching between the production requirements of cigarette strips with carton paper and those without carton paper. This technology chooses Solution 2, with the focus on: ensuring the quality of the transformation, balancing, saving costs and improving efficiency.

[0120] 1. In order to adjust the size of the conveying channel of the YB65 carton packaging machine, it is necessary to improve the design of the left spiral plate 4, the right spiral plate 6, the left bracket 13, and the right bracket 12.

[0121] 1.1 Improved design of left spiral plate 4.

[0122] The axis of the mounting hole of the left spiral plate is shifted to the left by ΔL2=13.5mm to meet the requirements of the adjustment of the ruler in the width direction of the cigarette strip, and the left spiral plate can be freely adjusted in the width direction, taking into account the production requirements of the paper with or without a strip box; the height on the right side is reduced by ΔS'=2mm (from 48mm to 46mm) to meet the requirements of the height direction of the cigarette strip, and the height of the right side of the spiral plate is improved from 48mm to 46mm. The total length of this part is 180mm, which meets the requirements of the height direction of the cigarette strip. This is conducive to the production of stripless boxes and will not affect the production of strip boxes. The size of 46mm is based on the thickness of two boxes of cigarettes (47mm) and is obtained through multiple tests. Since the cigarette strips without strip boxes are prone to looseness and uneven arrangement during pushing, which directly affects the next process (precise positioning), the height direction of 46mm can play a damping role for the cigarette strips when they enter the first lift, so that the cigarette strips enter the first lift neatly and accurately; the diameter of the mounting hole Without making any adjustment (the left side is the reference for the length direction of the cigarette strip, and the diameter of the mounting hole remains unchanged), the 8.5mm diameter hole 4 on the left spiral plate is changed to a long hole (and an open slot hole) with a center distance of 13.5mm in order to achieve the adjustment of the width direction of the cigarette strip in the conveying channel of the YB65 carton paper packaging machine, and to avoid the interference between the first lifter 10 and the left spiral plate 4 and the right spiral plate 6 at B and C. Figure 7 , 8 As shown:

[0123] 1.2 Improved design of the right spiral plate 6.

[0124] The axis of the right spiral plate mounting hole moves to the left by ΔL2=13.5mm to meet the requirements of the tobacco rod width adjustment; the right side height is reduced by ΔS'=2mm (from 48mm to 46mm) to meet the requirements of the tobacco rod height adjustment; the mounting hole diameter is Adjust to The hole with a diameter of 8.5mm on the right spiral plate 6 is changed to a long hole with a diameter of 14mm and a center distance of 13.5mm (and an open slot hole) in order to achieve the adjustment of the width direction of the tobacco strip conveying channel of the YB65 carton paper packaging machine, and to avoid the interference between the first lifter 10 and the left spiral plate 4 and the right spiral plate 6 at B and C. The maximum adjustment range in the length direction of the tobacco strip is (14-8.5) / 2=2.75, which meets the requirement of ΔL3=2.5mm. The dimensions of the right spiral plate before and after the improvement are as follows Fig. 9 , 10 As shown:

[0125] Through the implementation of this technology, when producing cigarette boxes, it is only necessary to properly adjust the installation hole positions of the left spiral plate 4 and the right spiral plate 6 to meet the production requirements, without replacing the left spiral plate 4 and the right spiral plate 6. Compared with redesigning the left and right spiral plates and then installing and debugging, this technical solution saves the cost of accessories, and at the same time, in the case of frequent brand changes, it reduces the installation of components and improves the efficiency of equipment transformation.

[0126] 1.3 Improved design of left bracket 13.

[0127] The height of the left bracket 13 is reduced by ΔS' = 2mm, which meets the height requirement of the cigarette strip without box paper, and allows the cigarette strip to be compressed by 1mm as a whole in the conveying channel, preventing the joints of the 5 groups of cigarettes in the cigarette strip from loosening and causing cigarette jams, which is a key parameter to ensure the high-speed operation of the equipment. Fig.11 shown.

[0128] 1.4 Improved design of the right bracket 12.

[0129] The height of the right bracket 12 is also reduced by ΔS'=2mm to meet the height dimension requirements of the cigarette strip without a box paper. Fig.12 shown.

[0130] The main reason for redesigning and replacing the left and right brackets instead of changing the original brackets is that the bracket structure itself is simple and the manufacturing cost is low. When changing the brand of cigarette sticks with a box, no adjustment gasket is needed to reduce the adjustment. Through the implementation of this technology, when producing cigarette sticks with a box, the left bracket 13 and the right bracket 12 need to be replaced to meet the production requirements.

[0131] As a preferred embodiment of the present invention, step S2 specifically includes the following steps:

[0132] Step S21, the length dimension of the tobacco rod in the first lifting channel is adjusted (the tobacco rod dimension changes from 282.5 mm to 280 mm).

[0133] The first adjustment reference for the length direction of the cigarette rod is the distance A=335mm from the machine body finishing surface K, that is, the left side of the running direction of the cigarette rod 5. The thickness of the pad 17 is changed to meet the change in the length direction of the cigarette rod 5. The length change of the cigarette rod 5 without box paper ΔL1=282.5-280=2.5mm, just reduce the thickness of the pad 17 by ΔL1=2.5mm. (See Fig.13 The first lifter hopper 16 lifts the cigarette rods 5 to the horizontal conveying channel of the YB95 cellophane packaging machine.

[0134] Step S22, the size of the tobacco rod in the first lifting channel in the width direction is adjusted (from 89.5 mm to 88 mm).

[0135] The first lifting channel cigarette strip width adjustment reference is the fixed wall 19, and the distance R between the movable wall 18 and the fixed wall 19 is adjusted to 88mm by adjusting the adjustment block 1 20 and the adjustment block 2 21 to meet the requirements of cigarette strips without box paper. (See Fig.14 (shown)

[0136] Step S23, adjusting the size of the tobacco rods in the first lifting channel in the height direction.

[0137] Since the first lifting channel runs in the vertical direction and there is no baffle in the height direction of the tobacco rod, no adjustment is required in the height direction.

[0138] Conclusion: The adjustment of the first lifting channel in the length, width and height direction of the cigarette rod only requires the modification of the thickness of the cushion block 17 to meet the requirements.

[0139] 2. In order to adjust the size of the first lifting channel at the junction of YB65 and YB95, it is necessary to improve the design of the cushion block 17.

[0140] The thickness of the pad 17 is changed to ΔL1 = 282.5-280 = 2.5 mm. The comparison before and after the modification is shown in the following figure ( Fig.15 (shown)

[0141] Through the implementation of this technology, when it is necessary to produce cigarette rods with a cigarette box, it is only necessary to replace the cushion block 17 with the original thickness of 8 mm.

[0142] As a preferred embodiment of the present invention, step S3 specifically includes the following steps:

[0143] Step S31, the length dimension of the tobacco rods in the horizontal conveying channel of the YB95 transparent paper packaging machine is adjusted (the length dimension changes from 282.5 mm to 280 mm).

[0144] The adjustment reference of the length direction of the horizontal conveying channel is the left side of the conveying direction of the cigarette strip (i.e. the working surface where the left folder 22, the left folding spring plate fixing frame 23, and the folding spring plate 24 are located). It is only necessary to adjust the right folding spring plate fixing frame 26, and then adjust the gap AE between the right folder 25 and the folding spring plate 24 by adjusting the adjustment piece 27 to 0.5mm to meet the requirements of conveying cigarette strips without box paper (see Fig.16 shown).

[0145] Step S32, the size of the tobacco rods in the horizontal conveying channel of the YB95 transparent paper packaging machine is adjusted in the width direction (from 89.5mm to 88mm).

[0146] The adjustment standard of the width direction of the horizontal conveying channel is that the elastic push rod 28 moves to the frontmost position D (6mm away from the first conveying channel fixed baffle 31). Fig.17By moving the front baffle 30, the length L of the horizontal conveying channel can be changed to meet the requirement of adjusting the size of the cigarette strip without box paper in the width direction.

[0147] Since the width of the cigarette strips ΔX=89.5-88=1.5mm, there are 4 cigarette strips in the horizontal conveying channel, ΔL4=4ΔX=4×1.5=6mm, so it is only necessary to move the front baffle 30 to the left by ΔL4=6mm to meet the adjustment requirement.

[0148] Adjustment method (see Fig.18 As shown): Loosen four screws 1 32 and one screw 2 33 to move the output base plate 41 to the left by ΔL4=6mm. However, when the output base plate 41 moves to the left, the right folding plate 35 will interfere with the side block 37 on the corner frame 36. Under normal circumstances, the front and rear positions of the second lifter 29 need to be adjusted to eliminate the interference. However, after the second lifter 29 is adjusted front and rear, its movement stroke and movement starting position also need to be adjusted accordingly. The entire adjustment process is cumbersome and complicated. If the size of the side block 37 on the corner frame 36 is appropriately adjusted, the production of two specifications of products, with and without cigarette boxes, can be met without adjusting the front and rear positions of the second lifter 29, thereby reducing the amount of equipment adjustment and greatly improving the adjustment efficiency when the product specifications are frequently changed.

[0149] Step S33, the horizontal channel of the YB95 transparent paper packaging machine is adjusted in the height direction of the cigarette rod (from 49mm to 47mm), see Fig.19 shown.

[0150] The height dimension of the horizontal conveying channel can be adjusted by directly adjusting the height of the upper cover plate 34 through four bolts 38 to meet the requirements of conveying cigarette strips without strip paper. When the upper cover plate 34 is adjusted downward by ΔS'=49-47=2mm, it will interfere with the left folder 22 and the right folder 25, causing the end transparent paper to be unable to pass through. Therefore, the height dimensions of the left folder 22 and the right folder 25 should be adjusted to meet the requirements of conveying cigarette strips without strip paper.

[0151] Conclusion: The YB95 conveying channel needs to be adjusted in the length, width and height directions of the cigarette strips, and the three special parts, the side block 37 of the diagonal frame 36, the left folder 22 and the right folder 25, need to be improved to meet the normal conveying of the cigarette strips without box paper.

[0152] 3. In order to adjust the size of the horizontal conveying channel of the YB95 transparent paper packaging machine, it is necessary to improve the design of the side block 37 of the diagonal frame 36, the left folder 22, and the right folder 25.

[0153] 3.1 The comparison of the dimensions of the side baffle 37 before and after the improvement is as follows: Fig. 20 , 21

[0154] 3.2 The comparison of the left folder 22 and the right folder 25 before and after the improvement is as follows: Fig. 22 , 23

[0155] Through the implementation of this technology, when it is necessary to produce cigarette boxes, only appropriate adjustments need to be made, and normal packaging production can be carried out without replacing these four parts.

[0156] As a preferred embodiment of the present invention, step S4 specifically includes the following steps:

[0157] Step S41, the size of the second lifting channel in the length direction of the tobacco rod is adjusted (282.5 mm becomes 280 mm).

[0158] 4.1.1 The second lifter hopper tobacco rod length direction size adjustment basis (such as Fig.24 As shown): It is the left side of the second lifter baffle 39. By adjusting the screw G to shrink the angle bracket 36 inwardly by ΔL1=282.5-280=2.5mm, the requirements for conveying cigarette strips without box paper can be met.

[0159] 4.1.2 The second lifting channel tobacco rod length direction dimension adjustment benchmark (such as Fig.25 ) is the working surface where the inner wall of the left folder 22 and the inner wall of the left movable baffle 42 are initially located. By adjusting the right fixed baffle 40 and the right folding plate 35 inward by ΔL1=2.5mm, the transportation of cigarette strips without a box can be met.

[0160] Step S42, the width dimension of the tobacco rod in the second lifting channel is adjusted (89.5 mm becomes 88 mm).

[0161] The second lifting channel tobacco rod width direction adjustment reference is the inner wall of the front baffle 30 ( Fig.26 As shown in the figure, the rear baffle 43 is fixed by the right folding plate 35 and the left folding plate 44, and is arranged opposite to the front baffle 30. The requirements for conveying cigarette strips without box paper are met by changing the sizes of the left folding plate 44 and the right folding plate 35. (That is, the size X of the left folding plate 44 and the right folding plate 35 is shortened by ΔL5=1.5mm), but considering that the transparent paper of the cigarette strips in the second lifting channel has been formed, and the change of the size by 1.5mm is very small, after testing, the size X of the left folding plate 44 and the right folding plate 35 is not adjusted and does not affect the passage of the cigarette strips. It is determined that no adjustment is made to the width direction of the cigarette strips in the second lifting channel, reducing the amount of equipment adjustment and improving the adjustment efficiency.

[0162] Step S43, adjusting the height dimension of the tobacco rods in the second lifting channel.

[0163] Since the second lifting channel moves in the vertical direction, the size in the height direction does not need to be adjusted.

[0164] Conclusion: The second lifting channel can adjust the dimensions of the length, width and height of the cigarette rods. It only needs to adjust the installation positions of the left folding plate 44 and the right folding plate 35. It can meet the requirements of conveying cigarette rods without cigarette boxes without changing its dimensions.

[0165] Comparative analysis of the advantages of this technical solution and the technical transformation of the equipment manufacturer.

[0166] The equipment technology manufacturer's transformation plan selects the geometric center line of the tobacco rod as the basis for adjustment, expanding or contracting in two directions. The force on the tobacco rod during channel transportation will be more stable, but more special parts will need to be adjusted and replaced, and the transformation and debugging time will also be longer. It is not suitable for production needs with frequent changes in brands.

[0167] In the process of improving the above four tobacco passages, the technical transformation of the main special parts and equipment manufacturers was compared, as shown in Table 2:

[0168]

[0169] Table 2 Statistics of special parts changes

[0170] By comparing Table 2, it can be seen that with this technology, 3 special parts need to be replaced and 5 need to be improved (simple structure and low processing cost). The remaining special parts only need to be adjusted in size or position to achieve the effect of technical transformation of the equipment manufacturer. When it is necessary to change back to the production of cigarette boxes, only 3 special parts (2 brackets and 1 pad) need to be replaced, and the rest can be adjusted appropriately.

[0171] After the successful implementation of this technology in the experimental unit, it will be promoted to all units in the plant in March 2024. Through actual application verification, with the same three maintenance personnel involved in the operation, the adjustment time for changing the number was shortened from 4 hours to 1.5 hours, and the cost of special parts was reduced from 1.2472 million yuan to 36,700 yuan (12 sets of equipment costs).

[0172] The effect of this technology on improving efficiency is shown in the following table compared with the technical transformation of equipment manufacturers.

[0173]

[0174] Table 3 Improvement benefit data table

[0175] From the comparison in Table 3, it can be seen that through the application of this technology, whether it is producing cigarette cartons with or without cartons, during the equipment adjustment process, it not only ensures the stability of product quality, but also greatly improves the efficiency of equipment replacement and transformation, reduces the cost of purchasing accessories, and appropriately reduces the adjustment steps, which effectively guarantees the smooth completion of the factory's production tasks throughout the year.

[0176] Although the present invention is described herein with reference to the illustrative embodiments of the present invention, the above embodiments are only preferred embodiments of the present invention, and the embodiments of the present invention are not limited to the above embodiments. It should be understood that those skilled in the art can design many other modifications and embodiments, which will fall within the scope and spirit of the principles disclosed in this application.
