Description

Technical Field

[0001] The present application relates to the technical field of bar product sorting, and more specifically, to a sorting device for a filter rod bin of a cigarette making machine. Background Art

[0002] In the prior art, the YF26A filter rod receiver is a dual-tube filter rod receiving device with two filter rod receiving units, which can support the conveying function of filter rods of various length specifications. The longitudinal conveying system of the filter rod receiver accelerates the filter rods conveyed by the transmitter and sends them to the transverse conveying system, and then the transverse conveying system conveys the filter rods to the filter rod receiving hopper. The filter rod supply capacity of the existing filter rod receiver is much greater than the production capacity of the cigarette making machine, so a filter rod receiving hopper for caching filter rods needs to be provided. The existing filter rod receiving hopper can usually achieve two groups of functions in terms of structural design: receiving and storing the filter rods conveyed by the transverse conveying system and controlling them between high and low levels; and continuously supplying filter rods to the filter rod cutting drum. Usually, two groups of photoelectric switches are arranged on both sides of the filter rod receiving hopper, which are respectively used to control the high and low levels of the material level. When the material level is low, the filter rod receiver starts to receive and convey the filter rods, and the transverse conveying system outputs the filter rods to the hopper. Under the action of the thrust of the conveying system, the stacking height of the filter rods in the hopper increases. When it reaches the high level, after a 3-second delay, the filter rod supply stops; under the action of the self-weight of the filter rods, the stacking height of the filter rods in the bin gradually decreases and continuously supplies to the filter rod cutting drum. Under the action of the transverse conveying system of the filter rod receiver and the apron at the filter rod outlet, the filter rods can be conveyed into the filter rod receiving hopper orderly and intact.

[0003] In the use of the existing filter rod receiver, the filter rods in the hopper are prone to roll and skew during the process of increasing and decreasing the stacking height. When the skewed filter rods enter the filter rod cutting drum, the blocking roller will be lifted, resulting in filter rod blockage and shutdown. In severe cases, the filter rod cutter will also be damaged. For the above problems, the existing solutions are usually: when the height difference of the filter rods is large, the operator manually flattens the filter rods to avoid the generation of skewed and horizontal filter rods; when there are skewed and horizontal filter rods, tweezers or even shutdown are needed to take them out. During the production process, the operator needs to observe the arrangement of the filter rods frequently, but still cannot avoid the horizontal filter rods entering the filter rod cutting drum, resulting in filter rod blockage and shutdown. Each time of filter rod blockage and shutdown needs to be processed for 10 - 15 minutes, which seriously affects the equipment efficiency and causes consumption of raw and auxiliary materials at the same time. Therefore, it is difficult to meet the requirements of lean production. Summary of the Invention

[0029] Now, various exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present application.

[0030] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way a limitation on the present application or its application or use.

[0031] Technologies, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, such technologies, methods and devices should be regarded as part of the specification.

[0032] In all the examples shown and discussed here, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0033] Example 1:

[0034] As Figure 1 shown, the present application provides a material arranging device for a filter rod bin of a cigarette making machine, including a pressing block 100; the outer shape of the pressing block 100 is such that it can move freely up and down along the gravity direction inside the filter rod bin LC of the cigarette making machine, and during the moving process, at least both ends of the pressing block 100 are in contact with the inner walls of two opposite sides of the filter rod bin of the cigarette making machine. When in use, the pressing block 100 is placed at the top of the filter rod stack temporarily stored in the filter rod bin of the cigarette making machine, which can ensure that the filter rods are neatly arranged during the ascending and descending processes.

[0035] Further, as Figure 2 shown, in one of the preferred technical solutions of this embodiment, parallel grooves 101 are provided on the lower end surface of the pressing block 100; the outer shape of the parallel grooves 101 is adapted to the curved surface shape formed by the upper end surfaces of the filter rods located in the upper layer when the filter rods are stacked side by side in multiple layers in the bin LC. The improved pressing block 100 can fit more closely to the upper end surface of the sequentially stacked filter rod stack.

[0036] Further, as Figure 3 shown, in one of the preferred technical solutions of this embodiment, rollers 102 for reducing friction are respectively provided at both ends of the pressing block 100 for contacting the inner wall of the filter rod bin of the cigarette making machine. The improved pressing block 100 will be more stable and smooth during the up and down movement, and can provide a continuous and stable downward pressure on the filter rod stack to keep the stacking of the filter rods orderly and neat.

[0037] Example 2:

[0038] As Figure 4 shown, this embodiment further improves the structure of the pressing block 100, and its structure includes: a bracket 110, a contact block 120 and a leveling chain 130; one contact block 120 is fixedly provided at each end of the bracket 110; both ends of the leveling chain 130 are fixedly connected to one of the contact blocks 120.

[0039] Further, as Figure 4 shown, in one of the preferred technical solutions of this embodiment, an inclined surface X for blocking the filter rods is provided at the part of the contact block 120 in contact with the filter rods. By setting the inclined surface structure in this embodiment, the inner wall of the contact block can further obtain a use effect equivalent to that of the filter rod stopper. During use, it is convenient for the leveling chain 130 to always stably fit the upper end surface of the stacked filter rods in a bow shape. In actual application, the operator holds the bracket and places the device in the filter rod bin. The leveling chain is freely laid on the upper layer of filter rods. Under its own gravity, the leveling chain generates a certain pressure on the upper layer of filter rods, and the filter rods generate a reaction force on the leveling chain, and the leveling chain will becomeFigure 4 The arc shape shown therein avoids the rolling and skew of the filter rod.

[0040] To meet the general use requirements of bins with different size specifications, in one of the preferred technical solutions of this embodiment, the distance between the two ends of the bracket 110 is set to be adjustable, and the relative distance between the two ends of the bracket 110 remains locked after adjustment. It should be noted that there are many structural solutions in the prior art that can realize the adjustment of the distance between the two ends of the rod member, and any of these solutions applied in this application is what this application focuses on protecting.

[0041] To clearly disclose the above technical solutions of this application, only one structural solution is clearly illustrated in this embodiment. Refer to Figure 4 , in this embodiment, the bracket 110 includes two link assemblies connected in parallel. The link assembly includes two links 111 hinged at adjacent ends, and the two links 111 are locked after being hinged and positioned at the ends. Preferably, the locking part can be realized by means of a fastening screw M. As Figure 4 and 7 shown, the bracket 110 made by connecting in parallel connection, the hollow part between the two link assemblies is convenient for the high and low position photoelectric detection of the filter rod, and then controls the height of the filter rod position.

[0042] As an embodiment, the bow angle of the bracket 110 can be adjusted by the fastening screw M between the two links 111 and the fastening screw M between the bracket 110 and the abutting block 120 to adapt to filter rod bins with different widths, as Figure 5 and 7 shown.

[0043] Further, although the fastening screw M shown in Figure 5 and 7 is used in this embodiment to tightly connect the bracket 110 and the filter rod stopper 121, the structural method of fixedly connecting the bracket 110 and the abutting block 120 by using other existing fixed connection methods in the art such as riveting and welding is also what this application claims to protect.

[0044] In the above structural solution, the number of link assemblies used in parallel is at least one, and the structural solutions of connecting the two abutting blocks 120 in parallel with any number or only using one link assembly are all what this application wants to protect.

[0045] As an embodiment, the flattening chain 130 includes two connecting pieces and multiple rod rollers arranged in parallel between the two connecting pieces. The diameter of the rod rollers matches the diameter of the filter rod. A plurality of hinge holes are arranged at intervals on each connecting piece, and both sides of each rod roller are respectively hinged in a hinge hole of one of the connecting pieces to form a chain track structure. In the working state, the filter rod is limited between two rod rollers to form a parallel groove 101, and the filter rod is limited in the parallel groove 101 to prevent the filter rod from skewing or lying horizontally. To meet the use requirement of adjusting the length of the flattening chain, any hinged part of the flattening chain can be disassembled and a new chain track connection can be re-established at the disassembled position. During use, the number of chain links can be increased or decreased by disassembling to achieve the technical purpose of adjusting the working length of the flattening chain.

[0046] As an embodiment, as Figure 4 - 6 shown in FIGS. 7 and 8, the rod rollers at both ends of the flattening chain are arranged between the through holes on both sides of the abutting block 120, and the two are connected together by a flattening chain adjusting screw 131 passing through the through hole and the central hole of the rod roller. The length of the flattening chain can be adjusted by disassembling and installing the flattening chain adjusting screw 131.

[0047] It should be noted that the above chain track structure is similar to the structural solutions of chains or crawlers, and the existing hinge structure used in chains is adopted to complete the movable connection.

[0048] The roller 102 is rotatably arranged on the outer side of the abutting block 120. During the rising and falling process of the filter rod, the roller 102 slides closely along the inner wall of the filter rod bin, and the two abutting blocks 120 on both sides block the filter rods on both sides.

[0049] Preferably, the number of the rollers 102 is multiple.

[0050] In this embodiment, the skewed and horizontally placed filter rods in the hopper are generated by the rolling of the filter rods during the rising and falling process. Under the action of the rollers, the device can freely rise and fall with the height of the filter rod position. The flattening chain gently presses on the filter rod to make the filter rod orderly and neat, and the skewing condition of the filter rod during the rising and falling process is improved through this device. Therefore, this device avoids the generation of skewed and horizontally placed filter rods from the source, improves the supply condition of the filter rods, reduces the blockage rate of the filter rods, improves the operation efficiency of the equipment, and reduces the consumption of raw and auxiliary materials.

[0051] In summary, the beneficial effects that can be obtained by adopting the above structural solution of the present application are as follows:

[0052] In this application, by further providing a material arranging device for the filter rod bin of a cigarette making machine inside the filter rod bin of the cigarette making machine, it can ensure that the filter rods are neatly arranged during the ascending and descending processes. During use, the operator places this device into the filter rod bin, and under its own gravity, this device gently presses flat on the surface layer of filter rods, effectively spreading out the upper layer of filter rods in an orderly manner. In the feeding state, during the ascending process of the filter rods, the filter rods push this device upward; during the descending process of the filter rods, this device closely adheres to the filter rods and blocks downward under its own gravity, so it can effectively ensure that the filter rods remain neatly arranged throughout the movement process.

[0053] Furthermore, the parallel grooves provided on the lower end surface of the pressing block can make the outer shape of the lower end surface of the pressing block match the outer shape of the upper end surface when the filter rods need to be neatly stacked, and thus can always maintain the filter rods located in the filter rod bin of the cigarette making machine in a neatly stacked and orderly state during the use state, further effectively preventing the placement position of the filter rods in the bin from being skewed.

[0054] Furthermore, the rollers provided on both sides of this device are used for rolling along the wall, which can effectively prevent the filter rods from being blocked due to excessive ascending resistance; and it is easier to realize that during the descending process of the filter rods, this device closely adheres to the upper end surface of the filter rod stack and rolls downward under its own gravity, which can effectively ensure that the placement positions of the filter rods located in the bin remain neatly arranged during the process of the stacking height of the filter rods in the bin decreasing.

[0055] Furthermore, by further adopting a structure composed of a bracket, an abutting block, and a flattening chain for the above-mentioned pressing block in this application, it can greatly reduce the structural material used for the pressing block, and thus provide a hardware basis for the lightweight of the product structure and the adjustable structure size. The improved pressing block can improve its service life by replacing the flattening chain, and by replacing the flattening chain with different bottom groove outer shapes, the universality of this device in processing filter rods with different diameters can also be improved.

[0056] Furthermore, by setting the structure of the bracket so that the distance between the two ends can be adjusted, this product can be further used in bins with different specifications and sizes, and thus a wider product application range can be obtained.

[0057] Furthermore, by setting the flattening chain in a chain track structure, it can not only meet the fitting requirements when adapting to the change of the upper end surface shape of the filter rod stack, but also dynamically maintain the filter rods in a parallel stacking storage state under the condition of the change of the number of filter rods in the bin, and thus provide a reliable operation guarantee for the continuous stability of filter rod processing.

[0058] Furthermore, using a connecting rod structure to make the bracket can facilitate the assembly of the product and the adjustment of the assembly position.

[0059] Furthermore, the cavity provided in the abutting block can store the grease required for lubricating the roller, providing a structural guarantee for keeping the roller rotating smoothly for a long time.

[0060] Furthermore, the multi-roller structure setting scheme can make the contact between the pressing block and the wall of the magazine more stable, and thus obtain a smoother and more stable use effect when the aligning device of the filter rod magazine of the cigarette making machine moves up and down in the magazine.

[0061] Although some specific embodiments of the present application have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and not for limiting the scope of the present application. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
