Description

Technical fields: This utility model relates to a yarn spindle bag packaging structure and a production line for realizing the yarn spindle bag packaging. Background technology: The applicant applied for an invention patent on November 26, 2021, entitled "Yarn Roll Packaging, Stacking Equipment and its Working Method", publication number CN114084416B. In this patent, the yarn roll (or yarn spindle, single-disc conical yarn spindle, which is shaped like a truncated cone, i.e., one end is a small end and the other end is a large end) is placed in an outer packaging bag (i.e., packaging bag K1, which is a thin plastic packaging bag to allow for heat sealing of the bag opening) without additional inner packaging. This makes the surface of the yarn roll prone to friction and wear during transportation. In addition, the packaging bag K1 is thin and is also prone to damage during transportation, affecting the quality and thus easily causing customer complaints. In order to solve the above problems, the applicant has specially designed a new packaging (yarn spindle bag packaging structure) to overcome the above problems.

[0001] In addition, each yarn roll in the outer packaging bag (i.e. packaging bag K1) of this invention patent is placed upright (the small end of the frustum-shaped yarn roll is facing up) or upside down (the small end of the frustum-shaped yarn roll is facing down), which makes the packaged items prone to bending and makes it difficult to ensure the flatness and stability of the stack when the packaging bags are stacked (they are prone to tipping over after being stacked high). Utility model content: In view of the above-mentioned shortcomings of the prior art, the purpose of this utility model is to provide a yarn spindle bag packaging structure. The yarn spindle bag packaging structure is reasonably designed, which helps to reduce damage to the outer surface of the yarn spindle and make the outer packaging bag flat after packaging.

[0002] The present invention relates to a yarn spindle bag packaging structure, characterized in that: it includes an outer packaging bag and a plurality of single-disc tapered yarn spindles with inner packaging bags arranged in a matrix in the outer packaging bag, wherein an odd number of single-disc tapered yarn spindles with inner packaging bags are arranged in each row in the outer packaging bag, and adjacent single-disc tapered yarn spindles in the same row have opposite orientations, and adjacent single-disc tapered yarn spindles in the same column have opposite orientations.

[0003] Preferably, the single-disc conical yarn spindle includes a yarn core and yarn wound on the yarn core. One end of the single-disc conical yarn spindle is a large end and the other end is a small end to form a frustum shape. The single-disc conical yarn spindle faces opposite directions, that is, the large end or the small end of the single-disc conical yarn spindle faces different directions.

[0004] Preferably, the outside of the aforementioned single-disc cone yarn spindle is sealed with a plastic bag to form an inner packaging bag.

[0005] Preferably, each row of the outer packaging bag contains three single-disc cone yarn spindles with inner packaging bags.

[0006] Preferably, the outer packaging bag is a nylon bag, woven bag, or snakeskin bag.

[0007] This utility model's yarn spindle bag packaging structure reduces friction and wear between the outer surface of the single-disc conical yarn spindle and the outer packaging bag by wrapping an inner packaging bag around the single-disc conical yarn spindle. Furthermore, since each row in the outer packaging bag has an odd number of single-disc conical yarn spindles, and adjacent single-disc conical yarn spindles in the same row face opposite directions, and adjacent single-disc conical yarn spindles in the same column face opposite directions, the arrangement of the single-disc conical yarn spindles in the outer packaging bag is reasonable, and the shape is relatively flat, making it less prone to bending. This is beneficial for the flatness and stability of subsequent stacking.

[0008] Another objective of this utility model is to provide a production line for a yarn spindle bag packaging structure. This production line for the yarn spindle bag packaging structure is reasonably designed and is conducive to realizing the formation of yarn spindle bag packaging structures.

[0009] The production line for the yarn spindle bag packaging structure of this utility model is characterized by: including a conveyor belt and a yarn spindle lifting and turning mechanism, an inner yarn spindle packaging mechanism, and an outer yarn spindle packaging mechanism arranged sequentially on the conveyor belt. The yarn spindle lifting and turning mechanism is used to lift and turn an even number of yarn spindles conveyed on the conveyor belt. The inner yarn spindle packaging mechanism is used to seal each yarn spindle conveyed on the conveyor belt in an inner bag. The outer yarn spindle packaging mechanism is used to package multiple yarn spindles conveyed on the conveyor belt in an outer packaging bag.

[0010] Preferably, the above-mentioned spindle lifting and turning mechanism includes a machine body and a lifting frame that can slide vertically on the machine body. The lifting frame is provided with two sets of sliding frames that are arranged opposite each other and can slide horizontally. The upper part of the two sets of sliding frames is provided with a turning plate that can rotate axially. When the two sets of sliding frames are close to each other, the turning plate can clamp the single disc cone spindle on the conveyor belt.

[0011] Preferably, the above-mentioned machine body is provided with a vertically arranged vertical track, the lifting frame is slidably connected to the vertical track, and a first motor and a first rotating block driven by the first motor are installed on the machine body below the lifting frame. The end of the first rotating block is rotatably connected to the first end of the first push rod, and the second end of the first push rod is rotatably connected to the lower surface of the lifting frame. The lifting frame is driven to lift and lower under the rotation of the first motor.

[0012] Preferably, the upper surface of the lifting frame is provided with parallel transverse rails, and two sets of sliding frames are respectively located on the outer side of the conveyor belt and are slidably connected to the transverse rails. A second rotating block is rotatably connected to the middle of the upper surface of the lifting frame, and a second push rod is rotatably connected to both ends of the second rotating block. The free end of the second push rod is rotatably connected to the sliding frame. A first cylinder is provided on the lifting frame, and the extension end of the first cylinder is connected to a sliding frame so as to drive the two sets of sliding frames to move closer or further apart when the first cylinder extends or retracts.

[0013] Preferably, the flip plate installed on one set of sliding frames is directly rotatably connected to the sliding frames, and the flip plate installed on another set of sliding frames is connected to the sliding frames through a rotary cylinder that can rotate 180 degrees. Under the action of the rotary cylinder, the flip plate and the clamped single-disc tapered yarn spindle are rotated 180 degrees.

[0014] The working method of the production line for the yarn spindle bag packaging structure of this utility model is as follows: The operator places each single-disc conical yarn spindle upright (the small end of the truncated cone-shaped yarn spindle is facing up) on the conveyor belt. When it moves to the yarn spindle lifting and turning mechanism, the even-numbered single-disc conical yarn spindle (i.e. the even-numbered one that will be put into the outer packaging bag later) is lifted and turned 180 degrees so that it is upside down (the small end of the truncated cone-shaped yarn spindle is facing down), while the odd-numbered ones remain stationary. This makes the overall shape of the packaging bag less prone to bending and more flat after the outer packaging bag is filled with yarn spindles, which is beneficial to the flatness and stability of subsequent stacking.

Detailed implementation method: It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be pointed out that the following detailed description is exemplary and intended to provide further explanation of the present application; unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0015] The present invention relates to a yarn spindle bag packaging structure, which includes an outer packaging bag 1 and multiple single-disc tapered yarn spindles 3 having inner packaging bags 2 arranged in a matrix in the outer packaging bag. An odd number of single-disc tapered yarn spindles 3 having inner packaging bags 2 are arranged in each row in the outer packaging bag 1. The orientation of adjacent single-disc tapered yarn spindles in the same row is opposite, and the orientation of adjacent single-disc tapered yarn spindles in the same column is opposite.

[0016] The single-disc conical spindle 3 includes a yarn core 301 and a yarn 302 wound on the yarn core. One end of the single-disc conical spindle is a large end and the other end is a small end to form a frustum shape. The single-disc conical spindle faces opposite directions, that is, the large end or the small end of the single-disc conical spindle faces different directions. When the single-disc conical spindle is placed upright, the small end faces upward. When the single-disc conical spindle is placed upside down, the small end faces downward.

[0017] The outer packaging bag 1 is formed by sealing the outside of the single cone yarn spindle with a plastic bag. The plastic bag can be a transparent plastic bag. The outer packaging bag 1 is a rectangular nylon bag, woven bag or snake skin bag, etc. The outer packaging bag 1 can have 3-8 rows, with an odd number of single cone yarn spindles 3 with inner packaging bags 2 arranged in each row. It is more preferably that 3 single cone yarn spindles 3 with inner packaging bags 2 are arranged in each row.

[0018] like Figure 1 , 2 The diagram shows a conventional outer packaging bag 1 with a single conical yarn spindle 3 placed upright. This arrangement makes the packaging bag prone to bending upwards when subjected to external force, which is not conducive to ensuring the flatness of the packaged item. Figure 3 , 4 This is a schematic diagram of the packaging structure of this application. Since each row of the outer packaging bag 1 has an odd number of single-disc tapered yarn spindles 3 with inner packaging bags 2, the adjacent single-disc tapered yarn spindles in the same row face opposite directions, and the adjacent single-disc tapered yarn spindles in the same column face opposite directions. This allows the adjacent single-disc tapered yarn spindles to support each other, making it less likely for the packaged item to be bent. This helps to ensure the flatness of its shape and provides better support and stability during subsequent stacking.

[0019] In order to package single-disc conical spindles to form the above-mentioned spindle bag packaging structure, this application proposes a production line for the spindle bag packaging structure, the specific structure of which is as follows.

[0020] The production line for yarn spindle bag packaging structure of this utility model includes a conveyor belt A1 and a yarn spindle lifting and turning mechanism B, an inner yarn spindle packaging mechanism A2, and an outer yarn spindle packaging mechanism A4 arranged sequentially on the conveyor belt. The yarn spindle lifting and turning mechanism B is used to lift and turn an even number of yarn spindles conveyed on the conveyor belt (this yarn spindle lifting and turning mechanism B is an improvement of this application, which will be described in detail later). The inner yarn spindle packaging mechanism A2 is used to seal each yarn spindle conveyed on the conveyor belt in an inner bag (this inner yarn spindle packaging mechanism A2 is a commercially available component, which can be a yarn spindle sealing machine produced by Shanghai Guhao Packaging Machinery Co., Ltd., which will not be described in detail below). The outer yarn spindle packaging mechanism is used to package multiple yarn spindles conveyed on the conveyor belt in outer packaging bags (the outer yarn spindle packaging mechanism is an improvement of this application, which will be described in detail later).

[0021] On this production line, single-disc cone yarn spindles sequentially pass through the action of the yarn spindle lifting and turning mechanism B (even-numbered spindles are lifted and turned, odd-numbered spindles are not lifted and turned), the inner packaging mechanism A2 wraps the single-disc cone yarn spindles with inner packaging bags, and the outer packaging mechanism performs outer packaging actions on multiple single-disc cone yarn spindles with inner packaging bags.

[0022] On the production line, the conveyor belt A1 can be a belt conveyor, a roller conveyor, or a platform that uses push plates to push materials, etc.

[0023] The spindle lifting and turning mechanism B includes a machine body B1 and a lifting frame B2 that can slide vertically on the machine body. The lifting frame B2 is provided with two sets of sliding frames B3 that are arranged opposite each other and can slide horizontally. The upper part of the two sets of sliding frames is provided with a turning disk B4 that can rotate axially (the axial direction refers to the rotation axis of the turning disk B4). When the two sets of sliding frames are close to each other, the turning disk B4 can clamp the single-disc conical spindle 3 on the conveyor belt.

[0024] During operation, the single-disc tapered yarn spindle 3 is conveyed by the conveyor belt to the yarn spindle lifting and turning mechanism B. The odd-numbered spindles are not driven to be lifted and turned, while the even-numbered spindles are driven to be lifted and turned. The odd-numbered and even-numbered spindles refer to the odd-numbered or even-numbered spindles in a certain outer packaging bag. In fact, every other single-disc tapered yarn spindle on the conveyor belt is driven to be lifted and turned 180 degrees (before feeding, the spindles are manually placed upright on the conveyor belt; the single-disc tapered yarn spindles transferred in the production workshop are placed upright on the transfer car and placed on the conveyor belt manually or by a robot during feeding). The intermittent driving of the single-disc tapered yarn spindles to be lifted and turned 180 degrees is existing technology and will not be described in detail here.

[0025] When the spindle lifting and turning mechanism is working, the two sliding frames B3 move closer to each other, and the turning discs B4 on the two sliding frames B3 clamp the single-disc tapered spindle that is placed on the conveyor belt. The lifting frame B2 rises, driving the single-disc tapered spindle to rise. Then, the turning discs B4 drive the single-disc tapered spindle to turn 180 degrees. Then the lifting frame B2 descends, and at the same time, the two sliding frames B3 move away from each other. The single-disc tapered spindle that has been turned 180 degrees (i.e., upside down) falls onto the conveyor belt, and the upside-down single-disc tapered spindle continues to travel on the conveyor belt.

[0026] Specifically, the machine body B1 is provided with a vertically arranged vertical track B5, and the lifting frame B2 is slidably connected to the vertical track B5. The machine body is equipped with a first motor B6 and a first rotating block B7 driven by the first motor to rotate. The end of the first rotating block B7 is rotatably connected to the first end of the first push rod B8, and the second end of the first push rod B8 is rotatably connected to the lower surface of the lifting frame B2. That is, the first motor B6, the first rotating block B7, the first push rod B8, and the lifting frame B2 constitute a crank-slider mechanism. The first rotating block B7 is driven to rotate under the rotation of the first motor, which in turn pushes the first push rod and the lifting frame to realize the lifting action.

[0027] The upper surface of the lifting frame B2 is provided with parallel transverse rails B9. Two sets of sliding frames B3 are located on the outer side of the conveyor belt and are arranged opposite to each other. The sliding frames B3 are slidably connected to the transverse rails B9. A second rotating block B10 is rotatably connected to the middle of the upper surface of the lifting frame (that is, the center of the second rotating block B10 is rotatably connected to the middle of the upper surface of the lifting frame). The two ends of the second rotating block are respectively rotatably connected to the second push rods B11. The free end of the second push rod is rotatably connected to the sliding frame. A first cylinder B12 is fixed on the lifting frame. The extension end of the first cylinder is connected to a sliding frame. That is, when the first cylinder extends or retracts, it drives a set of sliding frames to move. Then, through the second push rod and the second rotating block, it drives the other set of sliding frames to move closer or farther away, thus realizing the relative approach or relative distance between the two sets of sliding frames B3.

[0028] One set of sliding frames has a flip plate B4 directly rotatably connected to the sliding frame B3. Another set of sliding frames has a flip plate B4 connected to the sliding frame via a rotary cylinder B13 that can rotate 180 degrees. That is, the cylinder body of the rotary cylinder B13 is fixedly connected to a sliding frame, and the rotating end of the rotary cylinder B13 is connected to a flip plate. When the two sets of flip plates are close to each other and clamp the single-disc tapered yarn spindle, the rotary cylinder drives the flip plate to rotate, which in turn drives the clamped single-disc tapered yarn spindle to rotate 180 degrees, thus realizing the action of flipping the single-disc tapered yarn spindle 180 degrees.

[0029] For optimal design, each of the two sets of rotating discs is rotatably connected to two spaced-apart tapered nylon rollers B14. These tapered nylon rollers B14 rotate around their own axis. When the rotating discs hold a single tapered yarn spindle, the tapered rollers abut against the outer surface of the single tapered yarn spindle. The rotation of the tapered nylon rollers B14 reduces friction and wear on the outer surface of the single tapered yarn spindle. The extended lines of the centerlines of the two tapered nylon rollers B14 intersect to form an acute angle.

[0030] The yarn spindle outer packaging mechanism includes an outer packaging bag opening and pushing mechanism C and a yarn spindle bag turning mechanism D.

[0031] The outer packaging bag opening and pushing mechanism C includes a fixed frame C1 mounted on the machine body and a lead screw C3 rotatably connected to the fixed frame and driven to rotate by a second motor C2. The lead screw C3 has two sections of threads with opposite rotation directions. A first support plate C4 and a second support plate C5 are rotatably connected to the two sections of threads (the first support plate C4 and the second support plate C5 are perpendicular to the lead screw C3). The first and second support plates (free ends) are used to support the opening of the outer packaging bag to open it. The second support plate is provided with through holes C6, through which guide rods C7 are inserted. The guide rods are smooth rods and are arranged parallel to the lead screw. Both ends of the guide rods are fixed to the fixed frame. During operation, the second motor C2 drives the lead screw C3 to rotate, which in turn drives the first support plate C4 and the second support plate C5 to move away from each other. This opens the opening of the outer packaging bag fitted on the outside of the first support plate C4 and the second support plate C5, making it easier to push in the subsequent single-disc tapered yarn spindles with inner packaging bags (specifically pushed in by the first push plate C8).

[0032] The outer packaging bag opening and pushing mechanism C is located on the discharge side of the inner packaging mechanism A2 (i.e., the inner packaging mechanism A2 packages the single-disc conical yarn spindle with an inner packaging bag and then discharges it). Specifically, a platform surface A3 is provided between the inner packaging mechanism A2 and the outer packaging bag opening and pushing mechanism C to support and transport the single-disc conical yarn spindle with the inner packaging bag. The outer packaging bag is fitted onto the discharge side of the first support plate and the second support plate. Opposite to the discharge side, there is a first push plate C8 pushed by a second cylinder. The first push plate is perpendicular to the first support plate and the second support plate. The platform surface A3 is rectangular, and the first end of the platform surface A3 is aligned with the discharge side of the inner packaging mechanism A2. The material inlet is connected, and the second end of the platform surface A3 is connected to the feeding side of the outer packaging bag opening and pushing mechanism C. At the first end of the platform surface A3, there is also a second push plate C9 driven by a cylinder to extend and retract. The single-disc tapered yarn spindle is packaged into the inner packaging bag by the yarn spindle inner packaging mechanism A2 and output into the first end of the platform surface A3. The second push plate C9 pushes the single-disc tapered yarn spindle with the inner packaging bag one by one to move to the second end. When there are three single-disc tapered yarn spindles with the inner packaging bag near the second end of the platform surface A3, the first push plate C8 pushes the three single-disc tapered yarn spindles with the inner packaging bag into the outer packaging bag 1 with the guidance of the first support plate C4 and the second support plate C5.

[0033] The authorized invention patent (publication number CN114084416B) mentioned in the background technology uses a side support plate fixed on one side, and the other side support plate is driven by a cylinder to extend and retract. Although this is beneficial for opening the outer packaging bag, the side support plate driven by the cylinder is off-center from the symmetrical center of the conveyor belt, which makes it easy for the pusher plate to push the three single-disc tapered yarn spindles to deviate, which is not conducive to pushing each single-disc tapered yarn spindle into the outer packaging bag. In addition, the pusher plate and the cylinder are constantly subjected to the reaction force of the outer packaging bag opening, which affects the service life of the cylinder (currently, in field use, it needs to be replaced every three to five months). In this application, when opening the outer packaging bag, a lead screw synchronously drives the first support plate C4 and the second support plate C5 to move away from each other. Thus, the position of the outer packaging bag opening is aligned with the platform surface used to place multiple single-disc tapered yarn spindles, making it easier to ensure that the three single-disc tapered yarn spindles are pushed into the outer packaging bag in a straight line. With the help of the guide rod, the design of each component of the outer packaging bag opening and pushing mechanism of this application is more reasonable, more stable in use, and has a longer service life.

[0034] For a reasonable design, the first and second support plates are tapered near the discharge side. An elongated extension rod C10 is also welded to the outer surface of the first and second support plates near the discharge side. This extension rod C10 is convenient for insertion into the opening of the unopened outer packaging bag.

[0035] The first and second support plates are flared towards the feed side, meaning that the feed sides of the first and second support plates are inclined in opposite directions at an angle of 5-15 degrees. This design facilitates the first push plate to guide three single-disc conical yarn spindles with inner packaging bags into the first support plate, the second support plate, and the outer packaging bag. At the same time, an upper inclined plate C11 is provided on the fixed frame above the feed side of the first and second support plates, which also facilitates the introduction of the yarn spindles.

[0036] The aforementioned yarn spindle bag turning mechanism D includes a base D1 and a rotating platform D2 that can rotate 90 degrees relative to the base in a horizontal position. A swing frame D3 with a horizontal work position and a vertical work position and a conveyor belt D4 mounted on the swing frame are rotatably connected on the rotating platform D2. One end of the swing frame is rotatably connected to a rotating support frame D5 with a horizontal work position and a vertical work position relative to the swing frame D3.

[0037] In use, after the outer packaging bag is opened and pushed in by the preceding outer packaging bag-opening and pushing mechanism C, a certain number of single-disc conical yarn spindles with inner packaging bags are stuffed into the outer packaging bag, the second motor drives the first support plate and the second support plate to move closer together. The first support plate and the second support plate no longer tighten the outer packaging bag, and with the push of the first push plate, the outer packaging bag filled with yarn spindles is pushed out and placed above the conveyor belt D4. As the conveyor belt D4 works, the outer packaging bag filled with yarn spindles moves closer to the rotating support frame D5 (initially, the rotating support frame D5 and the swing frame D3 are set perpendicularly). After the conveyor belt D4 works for a few seconds, the outer packaging bag filled with yarn spindles is close to the rotating support frame D5, and the swing frame D3 swings by the horizontal machine. The machine switches to a vertical position (so that the outer packaging bag filled with yarn spindles also switches from a horizontal position to a vertical position), and the rotating table D2 drives the swing frame D3 to rotate 90 degrees so that the outer packaging bag filled with yarn spindles faces the operator. The operator can then perform threading or strapping operations at the opening of the outer packaging bag. After completing the threading or strapping operations, the rotating table D2 drives the swing frame D3 to rotate 90 degrees in the opposite direction. The swing frame D3 returns to the horizontal position, and the rotating support frame D5 swings to a position relatively level with the swing frame D3. The conveyor belt D4 starts to move so that the outer packaging bag on it can move to the subsequent position (the rotating support frame D5 swings to a position relatively level with the swing frame D3, so as not to restrict the conveying of the outer packaging bag).

[0038] The authorized invention patent (publication number CN114084416B) mentioned in the background technology uses a heat-sealing operation for the bag opening, that is, sealing with a sealing machine. It is for outer packaging bags with relatively thin plastic outer packaging bags. The outer packaging bags of this application are made of more wear-resistant and durable snake skin bags or woven bags, which cannot be operated by heat sealing machine. They can only be sealed by threading or binding. When sealing by threading or binding, if it is a horizontal conveyor belt, the operator needs to operate sideways, which is awkward and not convenient for operation. The mechanism of this application can turn the packaging bag to face the operator when threading or binding is required, thereby facilitating the operation.

[0039] Specifically, the bottom center of the rotating platform D2 is rotatably connected to the base D1. A gear disk D6 is provided on the outer periphery of the bottom of the rotating platform. The base is provided with a gear D8 that meshes with the gear disk and is driven by a third motor D7. Under the drive of the third motor, the gear disk D6 and the rotating platform D2 can be driven to rotate horizontally by 90 degrees.

[0040] The lower bottom of the swing frame D3 is rotatably connected to the upper part of the rotating platform D2. A third cylinder D9 is provided between the rotating platform and the lower bottom of the swing frame. The extension and retraction of the third cylinder drives the swing frame to a horizontal or vertical position (not completely perpendicular to the horizontal position). When the swing frame is in a horizontal position, it facilitates the movement of the conveyor belt D4. When the swing frame is in a vertical position, it facilitates the rotation of the support frame D5 to support the bottom of the outer packaging bag filled with yarn spindles.

[0041] The specific swing frame is a rectangular frame, with the conveyor belt D4 set in the frame. The free end of the telescopic rod of the third cylinder D9 is rotatably connected to the frame, and the cylinder body of the third cylinder D9 is fixed on the rotating platform.

[0042] The rotating support frame D5 is a rectangular frame (its long side is the same length as the wide side of the swing frame). One long side of the rectangular frame is rotatably connected to one end of the swing frame (i.e., the side away from the outer packaging bag opening and pushing mechanism C). A swing arm D10 extends from one short side of the rectangular frame. A fourth cylinder D11 is provided between the frame of the swing frame and the swing arm. When the fourth cylinder is working, it drives the rotating support frame to be flush with or perpendicular to the swing frame. When the rotating support frame D5 is in the position flush with the swing frame, it is beneficial for the conveyor belt D4 to transport the outer packaging bag full of yarn spindles. When the rotating support frame D5 is in the position perpendicular to the swing frame, it is beneficial for the rotating support frame D5 to support the bottom of the outer packaging bag full of yarn spindles.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
