Description

Technical Field

[0001] The utility model relates to a cotton bale bagging and feeding device. Background Art

[0002] On the cotton bale processing production line, the baler needs to bag the cotton bales after packaging. There are two main types of cotton bags currently used, one is cotton bagging and the other is plastic bagging. The appearance of plastic bagging is mainly used to realize the automation of cotton bagging. At the same time, in order to meet the realization of automatic bagging of cotton bagging, some cotton bagging currently has hot melt adhesive sheets at the predetermined position of the bag mouth to facilitate the picking of cotton bagging. Overall, given that fewer and fewer workers can be invested in the cotton processing production line, the automation of the cotton processing production line is an inevitable direction.

[0003] For manual bagging or sealing (manual bagging usually means manually sewing the bags), how the cotton bales are stored has relatively little impact. For automatic bagging or sealing, since the cotton bales need to be stacked regularly to facilitate accurate picking up by the machine, and accurate picking up is a prerequisite for accurate feeding, in order to provide better technical conditions for subsequent processes, the inventor believes that it is very necessary to provide a cotton bale bagging loading device for cotton bale bagging.

[0004] In some implementations, the cotton bags are made into a material roll, which is equivalent to a group of cotton bags being wound on a drum in an end-to-end manner to form a cotton bag roll. When in use, a winding device is required to unfold the wound cotton bags, and then the opened cotton bags are cut from the material roll by a cutting device. Since the cotton bags need to be stretched when they are wound, the bag length is inconsistent, and it is very likely that the cutting position is exactly the position where the bag tail is sealed. In view of this, in a further implementation, the material roll is no longer wound on a drum in an end-to-end manner, and what is wound on the material roll is a cotton tube without a sealed bag tail. Similarly, a cutting device and a tensioning device are also required to unfold the material roll to a predetermined length and then cut it. Since the tail and the bag opening of the cotton bag formed by cutting are not sealed, the tail of the material section needs to be sealed after cutting to form the cotton bag, and then the cotton bag is transferred to the bagging station for bagging. After the bagging is completed, the bag opening is sealed, and the overall structure is very complicated.

[0005] In view of the fact that the above method is too complicated, has too many links and has a certain failure rate, cotton mills reverted to the traditional mode of manual bagging after using it for a period of time.

[0006] In recent years, new cotton bag feeding devices have appeared, which are mainly used for feeding cotton bags. In order to meet the requirements of automatic feeding, two rows of circular hot melt adhesive sheets are designed on the bag surface of the cotton bag facing upward, and then the cotton bag is picked up by suction cups arranged in the same two rows using the airtightness of the hot melt adhesive sheets. However, this method is only applicable to cotton bags, and it is basically impossible to feed plastic bags that are more suitable for automatic feeding. The main reason is that whether it is cotton bags or plastic bags, they are usually stacked on the feeding platform, and in the storage and transportation state, there is a certain degree of compaction between the stacked cotton bags. When the cotton bag is a plastic bag, there is a certain degree of adhesion between the adjacent plastic bags. When the suction cup is used to pick up the top plastic bag, it is easy to bring up the next plastic bag. The lifted plastic bag is easy to shift with the currently sucked plastic bag, thereby affecting its feeding accuracy. Utility Model Content

[0051] For the convenience of description, the basic orientation in the embodiment of the utility model will be described below. One of the basic orientations is a loading direction, which is the basic direction. Figure 2 In the embodiment, the end where the cross arm 31 is located is the front end in the feeding direction, that is, Figure 2 The left direction in the figure is the feeding direction, and the right direction in the figure is the reset direction of the bag feeding mechanism after feeding. The front and rear directions can be determined from this. In the mechanical field, once the front and rear directions are determined, the left and right directions are also determined.

[0052] Among them, the front-to-back direction is also called the longitudinal direction, length direction, head-to-tail direction, etc., while the left and right are called the lateral direction, transverse direction, width direction, etc.

[0053] in, Figure 2 The cross arm 31 shown in FIG. 1 is determined based on the aforementioned basic orientation or basic reference system.

[0054] It should be noted that the feeding direction of the cotton bale bags is perpendicular to the conveying direction of the cotton bales. Obviously, the head and tail directions of the cotton bale bags when stored in the bag storage 1 are also perpendicular to the feeding direction of the cotton bale bags.

[0055] The position of the bag opening has nothing to do with the cotton bagging loading device involved in the embodiment of the utility model, although in the preferred embodiment, the side where the cotton bagging bag opening is located is Figure 1 The right side of the middle bag storage room 1.

[0056] There is another point that needs to be specially explained. Whether it is a plastic bag or a cotton bag, the finished product currently has two main bag surfaces. Based on the main bag surface, the two sides and the tail end are sealed to form a bag body. The timing of sealing at the bag mouth is after the bagging is completed, and the bag is sealed as a whole. What needs to be explained here is that no matter what kind of cotton bag, although it is stacked in the storage and transportation state and in the stacking state in the bag storage warehouse 1, it is different from the stacking of single-layer fabrics. The left and right side edges of the cotton bag in the folded state are in an arc transition shape based on the transition between the bag surfaces, so that there is a wedge-shaped space separated from each other at least at the edge between adjacent cotton bag bags, so that when picking up the cotton bag, it is easy to produce delamination here, although the speed of delamination may not be fast.

[0057] As an adaptability, when the cotton bag is covered with a cotton cloth bag, the cotton cloth bag should be a cotton cloth bag that can be sucked and picked up by a suction cup 32. This has been explained in the background technology part, that is, the cotton cloth bag is a cotton cloth bag with, for example, a hot melt adhesive sheet on the bag surface, and the position of the hot melt adhesive sheet on the cotton cloth bag can correspond to the position of the suction cup 32 with a determined position.

[0058] In the embodiment of the utility model, mainly with the help of the characteristic that the cotton bale bags stacked on the bag storage warehouse 1 are prone to delamination at the side, on the one hand, a blowing device is provided, and on the other hand, the cotton bale bags are picked up at the side to reduce the influence of picking up the current cotton bale bag on the current posture of the next cotton bale bag.

[0059] The cotton bagging and feeding device based on the concept of the utility model is described in detail below. Figure 1 The structure of the cotton bale bagging and feeding device shown is relatively complete and can realize more functions, but as far as bagging is concerned, it should be known that both plastic bags and cotton bags are very light and thin, and the bag grabbing area 12 of the bag storage warehouse 1 can store no less than one hundred bags at a time, but is usually controlled below five hundred bags, and three hundred bags are generally chosen.

[0060] At the same time, it should be known that the cotton baler with a relatively slow baling speed generally produces 9 to 10 bales per hour, while the current relatively high-speed cotton baler can produce up to 40 bales per hour, or even more. It can be seen that if 300 cotton bales are stacked in the bag grabbing area at a time, even the current cotton baler with a relatively high baling speed can be used continuously for seven and a half hours.

[0061] The bag storage warehouse 1 has a bag storage platform, which preferably adopts a platform with a flat table top. The platform can have a rigid table top, such as a table top made of stainless steel plate or other metal plate, or a table top made of other hard materials such as engineering plastics, stone, etc.

[0062] exist Figure 8 and Fig. 9 In the illustrated structure, a conveyor belt mechanism is used to provide the table panel. It should be known that in the mechanical field, the conveyor belt has a relatively strong conveying capacity, and cotton bags or plastic bags are generally lightweight materials. The tension of the conveyor belt is sufficient to keep the stacked bags relatively flat.

[0063] In addition, in order to ensure that the cotton bale bagging state in the bag storage 1 is relatively stable, Fig. 9 In the illustrated structure, a plurality of rollers 19 are provided on the lower side of the bag surface for supporting the cotton bale cover to provide multiple fulcrums, thereby solving the problem of excessive sagging of the conveyor belt due to gravity.

[0064] As mentioned above, the cotton bale bags are in the bag storage 1 in a state where the head and tail directions are perpendicular to the feeding direction, and the width of the conveyor belt used to support the cotton bale bags is relatively large relative to the weight of the cotton bale bags. Therefore, in some embodiments, a tensioning device can be provided for the conveyor belt mechanism to reduce the sagging of the conveyor belt caused by the influence of gravity.

[0065] Although the conveyor belt is provided mainly for realization in the preferred embodiment, it should be understood that even if a flexible member such as a conveyor belt is used, the suction cup 32 can still be satisfied with picking up the cotton bag cover.

[0066] The bag storage platform 1 firstly has a bag gripping area 12, in which the cotton bale bags are neatly stacked in a stacked manner.

[0067] In addition, Figure 8 In the illustrated structure, first ribs 18 are further provided at the front and rear sides of the bag grabbing area 12, and the distance between the corresponding front first rib and the rear first rib can be substantially consistent with the width of the cotton bag cover.

[0068] In some embodiments, for example, the rear first rib can be movably arranged between the bag grabbing area 12, for example, it can be assembled on the side frame of the bag storage warehouse 1 through an adjustment structure in the front and rear directions, and the distance between the two first ribs 18 can be adjusted according to different bag widths.

[0069] The presence of the two first ribs 18 can produce a limiting effect. In the embodiment of the utility model, even if the current cotton bale bagging has a certain influence on the next cotton bale bagging when being picked up, due to the corresponding configuration of the embodiment of the utility model, combined with the limiting effect of the two first ribs 18, it usually does not cause the next cotton bale bagging to shift.

[0070] The corresponding configuration is used to ensure that the next cotton bag is not displaced when the current cotton bag is picked up. This configuration is mainly achieved by using two basic configurations in coordination. The first basic configuration is to provide a horizontal blowing device on the discharge side of the bag grabbing area 12, which is the forward side of the discharge direction. Figure 7 The separation air pipe 11 shown in the figure is installed on the side where the gripping bag area 12 is located, that is, the front side of the gripping bag area 12.

[0071] Based on the above description, it can be known that the purpose of the blowing device is to separate the currently picked cotton bale bag from the next cotton bale bag by blowing air into the space between the current cotton bale bag and the next cotton bale bag, thereby reducing or eliminating the influence on the posture of the next cotton bale bag. Therefore, the blowing direction of the blowing device or the air nozzle of the blowing device rushes from the discharge side to the bag grabbing area 12.

[0072] It should be further known that the cotton bale is first picked up before loading, so the suction cup 32 is adapted, such as Figure 2 There are four suction cups 32 arranged in a row through the cross arm 31, and the suction cups 32 are used to suck the upper bag surface of the current cotton bale bag located on the discharge side.

[0073] exist Figure 2 In the illustrated structure, the number of suction cups 32 is one row, with four suction cups in total. The number of suction cups can be more, but usually no more than twenty.

[0074] Regarding the selection of the suction cup 32, the available options are φ10~φ100 (unit: mm) for the suction cup 32, and the optimal size is φ60. After experiments, it is found that the larger the size of the suction cup, the higher the success rate of picking up the cotton bag. Although the cotton bags are stacked neatly at the factory, the hot melt adhesive sheet set on the surface of the cotton bag may be deformed during storage and transportation. Deformation is an important test for the suction cup 32. Deformation often produces wrinkles, which will cause the suction cup to leak and fail when sucking the bag surface.

[0075] It can be seen from this that the larger the size of the suction cup 32, the larger the bag surface sucked, and the more bag surface defects may be faced. Therefore, for the selection of the suction cup 32, φ60 is a better choice, rather than larger.

[0076] Plastic bags face the same problem. Although plastic bag manufacturers will remind you that plastic bags need to be placed flat, it is difficult to ensure that the plastic bags can be stacked flat during storage and transportation, and wrinkles on the bag surface are relatively common.

[0077] In some embodiments, regarding the suction cup 32, two small-sized suction cups 32 can be arranged side by side at a predetermined suction point. While increasing the suction capacity of a single position, the impact of bag surface defects may only affect one of the suction cups 32. In other words, by exchanging quantity for area, the success rate of picking up cotton bales can be effectively improved.

[0078] The suction cups 32 arranged in parallel can be arranged in parallel longitudinally or in parallel transversely.

[0079] The picking up of the cotton bale after the suction cup 32 sucks the bag surface is achieved by the lifting mechanism, which is included in the bag feeding mechanism 3. The lifting mechanism is used to produce a picking up action. When picking up the cotton bale bag, the currently reset bag feeding mechanism makes the suction cup 32 align with the front upper bag surface of the current cotton bale bag, and then the output component of the lifting mechanism descends, so that the suction cup 32 is engaged with the current cotton bale bag, and a combination is generated based on the suction force, and then the output component of the lifting mechanism rises to complete the picking up action.

[0080] During the picking process, the blowing device can blow air continuously. In addition, for the blowing device, please refer to Figure 2 The lifting cylinder 33 shown in the figure can be co-operated with the blowing device. In other words, when the lifting cylinder 33 is working, the blowing device is connected to the air source, which is simple to control and synchronized with the picking action.

[0081] In addition, as a more economical consideration, the lifting cylinder 33 has two working strokes, namely, raising and lowering. The blowing device can be connected to the air source in accordance with the raising working stroke of the lifting cylinder 33, thereby reducing the burden on the air source while satisfying the blowing conditions.

[0082] As mentioned above, since the sides of cotton bale bags often have transition portions, thereby forming a wedge-shaped space, at the beginning of the rising stage of the picking action, the current cotton bale bagging and the next cotton bale bagging are separated on the feeding side purely based on the picking action, and the difficulty of separation becomes more and more difficult as time goes on. However, since a larger wedge-shaped space has been generated, the combination of blowing and picking action can effectively separate the current cotton bale bagging and the next cotton bale bagging, thereby reducing the impact on the posture of the next cotton bale bagging.

[0083] It can also be seen that in the embodiment of the present utility model, the picking up of the cotton bale bagging is different from the traditional two-side picking up, but is a single-side picking up, and there is no obvious increase in the total gas consumption.

[0084] The next step after the cotton bale bag is picked up is to transport the picked up cotton bale bag to the bagging platform of the bagging device. Therefore, the bag feeding mechanism 3 also includes a first linear drive mechanism. Obviously, the movement form of the linear drive mechanism is linear motion, that is, movement in the front and rear directions. The moving distance depends on the predetermined position of the bag grabbing area 12 and the bagging device. The design parameters are relatively clear and will not be repeated here. However, it should be known that the working stroke of the first linear drive mechanism for loading materials is greater than the width of the cotton bale bag. At the same time, based on the previous description, it can be seen that the width of the cotton bale bag is roughly equivalent to the width of the bag grabbing area 12. Therefore, in the first linear drive mechanism described below, a multi-stage telescopic mechanism is adopted to make the bag feeding mechanism 3 relatively compact.

[0085] Correspondingly, the driving object of the first linear drive mechanism is the aforementioned lifting mechanism that picks up the cotton bale bagging, so the frame of the lifting mechanism is installed on the output member of the first linear drive mechanism or is directly constructed on the output member of the first linear drive mechanism.

[0086] like Figure 2 As shown in the figure, the cylinder body of the lifting cylinder 33 is fixed at the end of the first-stage bag feeding arm 34.

[0087] In addition, in order to avoid motion interference, the position of the air nozzle is lower than the lower edge of the suction cup 32 when the lifting mechanism is raised.

[0088] Furthermore, considering the problem of motion interference, the blowing device includes a transverse tube installed on the first rib 18 located on the front side, and the transverse tube has blowing holes arranged horizontally to form the air nozzle. The air nozzle is directly formed by the blowing holes without any additional protruding parts.

[0089] In addition, the transverse tube can directly use the upper edge of the first rib 18 as the mounting base, and the transverse tube can be a rigid tube. Therefore, there can be only one or two fixing points. For example, the fixing point is only set at the left end of the bag grabbing area 12 in the figure, relying on the rigidity of the transverse tube itself to hold the position.

[0090] It should be noted that if the blowing device is Figure 2 The lifting cylinders 33 shown in the figure share a common air source, and the air source pressure used to drive the cylinders is usually relatively high, generally above 0.4 MPa, and the gas blown out through the blowing holes is sufficient to quickly impact the rear side of the bag storage warehouse 1.

[0091] In addition, the shape of the blowing hole can be a round hole or an elongated hole. When an elongated hole is used, the extending direction of the elongated hole is horizontal.

[0092] When the picking work stroke ends, as mentioned above, at this time, for example, the lifting cylinder 33 stops working, and the blowing can also stop at the same time, and then the bag feeding mechanism 3 transports the picked cotton cloth bag to the bagging platform of the bagging device. One issue to consider at this time is that since the cotton bagging is picked up on one side, this requires that the stroke of the lifting mechanism should not be too large, otherwise it will lead to the accuracy of the material discharge when the bag feeding mechanism 3 delivers the material into place. Therefore, the working stroke of the lifting mechanism should not be too large. Taking the maximum material level of the bag storage warehouse 1 as a reference, the working stroke of the lifting mechanism should not be greater than 3.5 times the maximum material level of the bag storage warehouse 1, so as to ensure the accuracy of the cotton bagging in place when unloading.

[0093] At the same time, the working stroke of the lifting mechanism should not be too small, otherwise, when the picking action is completed, the cotton bag currently picked up may not be completely separated from the next cotton bag, especially the rear part. At this time, the first linear drive mechanism moving forward may cause the next cotton bag to be pulled and displaced. In view of this, the working stroke of the lifting mechanism should not be less than 1.5 times the maximum material level of the bag storage 1.

[0094] Preferably, the working stroke of the lifting mechanism is 2.35 times the maximum material level of the bag storage warehouse 1.

[0095] The basic reason why the first linear drive mechanism adopts a multi-stage arm is explained in the previous article, but it should also be known that without using the multi-stage arm, the overall structure will only be less compact, but the "usability" will not be affected. In addition, the reliability of the multi-stage arm is slightly worse than that of the single-stage arm. The two options have their own advantages and disadvantages.

[0096] The most typical application of multi-stage arms is multi-stage cylinders, such as multi-stage air cylinders. As multi-stage air cylinders are common components in the mechanical field, they will not be described in detail here.

[0097] The following describes a multi-stage arm used in an embodiment. The multi-stage arm uses a two-stage telescopic arm. The main consideration is to ensure reliability. As mentioned above, the more stages there are, the worse the reliability. At the same time, the overall working stroke must meet the needs of loading and ensure compactness. The two-stage arm combines these two aspects, with relatively good reliability, compactness can also be guaranteed, and can also meet the requirements of loading for the working stroke.

[0098] It should be known that, without affecting the bagging, the cotton bagging feeding device and the bagging device are basically close to each other. The position for picking up the cotton bagging is the front edge of the cotton bagging. The working stroke of the secondary telescopic arm is usually less than twice the width of the cotton bagging to meet the requirements of the linear motion working stroke for feeding, and it is not necessary to use more stages.

[0099] Figure 2The secondary telescopic arm shown is realized by a synchronous belt mechanism, and the secondary telescopic arm uses only one set of power assembly 37, and the specific configuration is as follows:

[0100] The main fixing plate 371 is formed by Figure 5 The second fixing hole 379 shown in FIG. Fig.10 The mounting longitudinal beam 26 shown in FIG. 1 is a frame in the synchronous belt mechanism. The main fixed frame 371 has a secondary guide portion for providing guidance in the extension direction of the secondary telescopic arm, such as Figure 5 and Figure 6 Secondary slider 377 is shown.

[0101] Figure 6 In the embodiment, there are four secondary sliders 377 arranged in two rows and two columns, and each row of secondary sliders 377 is connected to a Figure 4 The secondary linear track 351 shown in the figure cooperates to form a secondary linear track pair.

[0102] Figure 4 The secondary bag feeding arm 35 shown in the figure is roughly a rectangular frame structure, two relatively long frames are provided with secondary linear rails 351, and two relatively short frames are plate frames, and the plate frames are provided with synchronous pulleys 352, and there are four synchronous pulleys 352.

[0103] At the same time, the two relatively long frames are also provided with a primary rail 354 on the lower side, that is, the secondary rail 351 and the primary rail 354 are both provided on the relatively long frame of the secondary arm 353, the upper side is the secondary rail 351, and the lower side is the primary rail 354. The secondary rail 351 and the secondary slider 377 form a secondary rail pair, and the primary rail 354 and the secondary slider 377 form a secondary rail pair. Figure 3 The first-level slider 342 cooperates to form a first-level linear rail pair.

[0104] The power assembly 37 adopts a synchronous belt mechanism for transmission, wherein the power assembly 37 includes a first motor 374 mounted on a main fixed plate 371, the first motor 374 is equipped with a driving synchronous pulley 373 through a coupling 375, and an idler wheel 372 is respectively provided on both sides below the driving synchronous pulley 373. Since the idler wheel 372 does not participate in the transmission, it can be a synchronous pulley or an ordinary flat pulley.

[0105] Figure 2 The second synchronous belt 36 in the drive synchronous pulley 373 has a relatively large wrap angle by being wound around the two idler pulleys 373, and then the second synchronous belt 37 bypasses the two idler pulleys 373 and passes downward. Figure 6In the embodiment, the secondary slider 377 is located at the lower side of the main fixed plate 371, and the idler wheel 373 is installed on the idler wheel frame. The idler wheel frame 373 is roughly a rectangular channel structure. The second synchronous belt 36 passes around the idler wheel 373 and is fixedly connected to the plate frames at both ends of the secondary arm 353. Figure 2 In the embodiment, when the active synchronous pulley 373 rotates clockwise, the second synchronous belt 36 moves to the right due to the fixed arrangement of the main fixed plate 371, thereby driving the secondary arm 353 fixedly connected to both ends of the second synchronous belt 36 to move to the right. Conversely, if the active synchronous pulley 373 rotates counterclockwise, the secondary arm 353 moves to the left.

[0106] Looking at the movement of the primary arm 341, the first synchronous belt 38 is wound around Figure 4 On the synchronous pulley 352 in the middle, the first synchronous belt 38 adopts an open structure, one end of the first synchronous belt 38 is fixedly connected to the primary arm 341, and the other end is fixed to the main fixed plate 371. Since the synchronous pulley 352 moves together with the secondary arm 353, for example, Figure 2 When the belt moves to the left, the synchronous belt wheel 352 on the left side will rotate clockwise, and the belt edge on the lower side will move to the left, thereby pulling the primary arm 341 fixed on the belt edge to move to the left.

[0107] It can be seen that the primary arm 341 and the secondary arm 353 move in the same direction, thereby achieving synchronous extension and retraction.

[0108] from Figure 1 As can be seen in FIG. 1 , since the bag feeding mechanism 3 needs to be arranged, the bag feeding mechanism 3 needs to be located above the bag grabbing area 12 of the bag storage 1, and the bag feeding mechanism 3 needs support, which is provided by Figure 1 and as mentioned above, the lifting stroke of the lifting cylinder 33, for example, having three rods, in the bag feeding mechanism 3 should not be too large. In other words, the height of the bag feeding truss 2 is relatively small. If the material is directly fed to the bag grabbing area 12, it is very easy to be interfered by the bag feeding truss 2 and the bag feeding mechanism 3. Therefore, in a preferred embodiment, since the bag storage platform also includes a bag preparation area 13, it is used to feed the material in the bag preparation area 13 to avoid the bag feeding truss 2 and the bag feeding mechanism 3.

[0109] Furthermore, the bag grabbing area 12 and the bag preparation area 13 are arranged on a conveying mechanism to convey the cotton bale bags prepared in the bag preparation area 13 to the bag grabbing area 12. In the use state, the bag preparation area 13 is first loaded with materials, and then the conveying mechanism is started to convey the cotton bale bags currently held by the bag preparation area 13 to the bag grabbing area 12, and then the bag preparation area 13 is loaded with materials again. After the cotton bale bags in the bag grabbing area 12 are consumed, the conveying mechanism is started to convey the cotton bale bags currently held by the bag preparation area 13 to the bag grabbing area 12.

[0110] It can be seen from this that the bag preparation area 13 should avoid the bag delivery mechanism 3.

[0111] Finally, in order to further adjust according to the on-site conditions, the bag storage 1 is installed on a base assembly 4 through a horizontal adjustment mechanism; accordingly, the adjustment direction of the horizontal adjustment mechanism is the cotton bale wrapping direction.

[0112] The base assembly 4 indicates that Figure 7 In the illustrated structure, the whole is a frame structure with a plurality of legs 41. In the figure, the lower end of the legs 41 is equipped with a Foma caster 42, which can be further adjusted according to the on-site conditions.

[0113] A movable linear rail 43 is provided on the top of the base assembly 4, and the bag storage warehouse 1 cooperates with the movable linear rail 43 to form a movable linear rail pair. At the same time, a locking device is provided on the bag storage warehouse 1 to lock the bag storage warehouse 1 to the base assembly 4 after the bag storage warehouse 1 is adjusted into place relative to the base assembly 4 in the direction of the movable linear rail 43.
