Description

Technical Field

[0001] This invention belongs to the field of bar conveying technology, specifically referring to an intelligent automatic suspended conveying device for bar transfer. Background Technology

[0002] The process of processing cotton yarn and winding it onto the bobbin in a textile mill is as follows: First, the raw cotton is opened, impurities are removed, and it is mixed to form a uniform cotton slab. Then, it enters the carding process, where the fibers are straightened and parallel by carding cloth to form a sliver. The sliver is then drawn and combined multiple times by a drawing frame to improve uniformity and strength before entering the roving process, where it is twisted to form a roving with a certain strength. The roving is further drawn and twisted by a spinning frame to produce a fine yarn that meets the fineness requirements. Finally, the fine yarn passes through a winding process to remove yarn defects and is wound into a cone yarn. After being twisted and strengthened by a doubling twister, the cotton yarn is evenly wound onto the bobbin by an automatic winding device to form a neat yarn package, which is convenient for subsequent weaving or dyeing processing.

[0003] Currently, after the wire rods are wound, they are collected into turnover boxes. Once the turnover boxes are full, they are loaded onto a cart for transport. This method of transport is not only slow but also labor-intensive. Furthermore, due to the limited aisle space in the factory, the wire rods may fall off during transport because the turnover boxes are unstable. Therefore, the current level of intelligence and automation in the wire rod transport process is relatively low. Improving the efficiency and stability of wire rod transport has become an urgent problem to be solved. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide an intelligent automatic suspended conveying device for lean wire transfer, so as to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted in this invention is as follows: An intelligent automatic overhead conveyor device for lean wire transfer is proposed, comprising: A suspended track is set on the collection path of the rod, forming a closed loop; Multiple sliding steer vehicles are connected end to end within the suspended track and can be driven by drive wheels to move cyclically around the path of the suspended track; Multiple lifting devices are correspondingly installed on each of the sliding steer vehicles; The lower end of the lifting device is provided with a hanger for loading the wire rod, and a retaining baffle is provided on the collection path of the wire rod. The retaining baffle is at the same height as the hanger and can allow the wire rod to fall off the hanger. A guide box and a turnover box are provided below the retaining baffle, and the wire rod enters the turnover box in an orderly manner from the guide box.

[0006] Furthermore, a torsion spring is provided at the connection between the hanger and the lifting device. The hanger is in a vertical position (first position) and a horizontal position (second position). The hanger is in the first position under the action of the torsion spring. When the hanger and the rod pass through the blocking baffle, the hanger moves from the first position to the second position. When the rod falls off the hanger, the hanger elastically returns from the second position to the first position.

[0007] Furthermore, the hanger includes a wire rod and an elastic hinge seat. The wire rod is fixed to the outer wall of the elastic hinge seat, and the torsion spring is installed inside the elastic hinge seat. The elastic hinge seat is elastically hinged to the end of the hanger through the torsion spring.

[0008] Furthermore, the retaining baffle is constructed as a rectangular plate, and the retaining baffle is vertically installed on the collection path of the wire rod. The retaining baffle has a retaining groove for the lifting device and the hanging device to pass through. The width of the retaining groove is smaller than the diameter of the wire rod, so that the wire rod is retained by the retaining baffle.

[0009] Furthermore, the flow guide box is fixedly installed below the retention baffle, and the flow guide box is provided with a flow guide plate inside. The flow guide plate is constructed as an inclined plate, with one end of the flow guide plate near the retention baffle being higher than the other end. The turnover box is detachably installed below the flow guide box.

[0010] The suspension track includes a track box, the top of which is provided with a slide rail and the bottom of which is provided with a track groove. The sliding vehicle includes a pair of support wheels that are rolled in the track groove, and a linkage rod is provided between the pair of support wheels. The linkage rod is slidably disposed in the slide rail.

[0011] Furthermore, the linkage rod protrudes upward from the slide rail, the drive wheel is positioned above the track box, and the edge of the drive wheel is provided with a plurality of centrally symmetrically distributed teeth, with a tooth groove between any two adjacent teeth. The drive wheel is configured to be driven to rotate by a drive shaft, and when the drive wheel rotates, it meshes with a plurality of linkage rods inside the track box to drive the support wheel to move within the track box.

[0012] Furthermore, a connecting rod is provided between any two adjacent sets of the support wheels, and the multiple sets of support wheels provided in the track box are linked together through the connecting rod.

[0013] Furthermore, the lifting device includes a first connecting rod and sleeves and a second connecting rod disposed at both ends of the first connecting rod. The first connecting rod is constructed as an "L"-shaped rod. The sleeve is sleeved on the top end of the connecting rod and fixed to the first end of the first connecting rod. The second connecting rod is horizontally disposed at the second end of the first connecting rod.

[0014] Furthermore, a guide rail is fixedly provided on the outer wall of the track box, and a guide rod is fixedly provided on the outer wall of the first connecting rod corresponding to the guide rail, and the guide rod slides within the guide rail.

[0015] Beneficial effects: This invention features a suspended track along the collection path of the wire rod production line, and includes a retaining baffle, a flow guide box, and a turnover box at the wire rod collection point. Workers simply place the wound wire rod onto the hanger at the bottom of the lifting device. As the hanger carries the wire rod past the retaining baffle, the baffle causes the wire rod to detach from the hanger and flow orderly into the turnover box. This automatic collection and processing improves transfer efficiency and stability, enhances intelligence and automation, and reduces manual labor intensity. Attached Figure Description

[0020] The accompanying drawings are provided to further understand the embodiments and form part of the specification. They are used together with the embodiments for explanation and do not constitute a limitation on the embodiments. Detailed Implementation

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection.

[0022] In the description of the embodiments, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments.

[0023] On the production line for bobbin winding, the finished bobbins are typically collected one by one by textile workers into a transfer box 70. The full transfer boxes 70 are then moved one by one onto a trolley for off-line transport. Since the entire process requires manual intervention, the workload of textile workers increases, and the production line is relatively crowded, leading to bobbins falling off. Therefore, to improve the efficiency and automation of bobbin transport, this invention provides an intelligent automatic suspended conveying device for bobbin transport. This device mainly includes a suspension track 10, a sliding trolley 20, a lifting device 30, and a hanging device 40.

[0024] The suspension track 10 is set on the collection path of the wire rod and forms a closed loop. Multiple sliding trolleys 20 are connected end to end in the suspension track 10 and can be driven by the drive wheel 01 to move around the path of the suspension track 10. Multiple lifting devices 30 are correspondingly set on each sliding trolley 20. The lower end of the lifting device 30 is provided with a hanging device 40 for loading the wire rod.

[0025] In some embodiments, the suspension track 10 is made of stainless steel and is installed by a suspension bracket. The suspension track 10 is laid out according to the production line where the wire is wound, so that the suspension track 10 can pass through all the positions where the wire is collected. The workers only need to place the wound wire on the hanger 40 at the lower end of the hanger 30. The wire on the hanger 40 moves along the suspension track 10 to the set position for collection and processing, without the need for manual transfer.

[0026] like Figure 1 As shown, furthermore, a retaining baffle 50 is provided on the collection path of the wire rod, wherein the retaining baffle 50 is at the same height position as the hanger 40. When the hanger 40 carries the wire rod past the retaining baffle 50, the retaining baffle 50 can cause the wire rod to fall off the hanger 40.

[0027] Meanwhile, a flow guide box 60 and a turnover box 70 are provided below the retaining baffle 50. The wire rods enter the turnover box 70 in an orderly manner from the flow guide box 60, and the wire rods are automatically collected and processed. Then the hanger 40 continues to follow the hanger 30 along the suspension track 10, waiting to install the wire rods again in the next cycle.

[0028] like Figure 2 As shown, a torsion spring is provided at the connection between the hanger 40 and the lifting device 30. The hanger 40 is in the first position when it is upright and in the second position when it is horizontal. The hanger 40 is in the first position under the action of the torsion spring. When the hanger 40 and the rod pass through the retaining baffle 50, the hanger 40 moves from the first position to the second position. When the rod falls off the hanger 40, the hanger 40 elastically returns to the first position from the second position.

[0029] In the initial state, the relative positions of the hanger 40 and the lifting device 30 are in the first position. At this time, under the action of the torsion spring, the hanger 40 and the lifting device 30 can maintain a relatively stationary position, and there is an elastic restoring force between the hanger 40 and the lifting device 30 that allows for elastic movement from the second position to the first position.

[0030] In some embodiments, the hanger 40 includes a wire rod 41 and an elastic hinge seat 42. The wire rod 41 is fixed to the outer wall of the elastic hinge seat 42. A torsion spring is installed inside the elastic hinge seat 42, and the elastic hinge seat 42 is elastically hinged to the end of the hanger 30 through the torsion spring.

[0031] Specifically, the internal structure of the elastic hinge seat 42 is hollow, and a torsion spring is fixedly installed inside. The end of the corresponding lifting device 30 is provided with a slot that matches the torsion spring. One end of the torsion spring is locked into the end of the lifting device 30. The elastic hinge seat 42 can rotate around the center of the end of the lifting device 30. When the elastic hinge seat 42 rotates, the torsion spring is subjected to force and has elastic potential energy for elastic recovery. The initial state of the wire rod hanging rod 41 is vertically upward and in the first position. When the wire rod hanging rod 41 deflects, the wire rod hanging rod 41 has elastic restoring force under the action of the torsion spring.

[0032] Generally, the length of the rod 41 is greater than or equal to the length of the rod, and the diameter of the rod 41 is smaller than the inner diameter of the rod. This makes it easy to load and unload the rod from the rod 41 and ensures stability during the conveying process.

[0033] like Figure 4 As shown, the retaining baffle 50 is constructed as a rectangular plate and is vertically installed on the collection path of the wire rod. The retaining baffle 50 has a retaining groove 500 for the lifting device 30 and the hanging device 40 to pass through. The width of the retaining groove 500 is smaller than the diameter of the wire rod, so that the wire rod is retained by the retaining baffle 50.

[0034] In some embodiments, the baffle 50 is made of stainless steel rectangular plate, and an "L"-shaped interception groove 500 is provided on the baffle 50. The short side of the "L"-shaped interception groove 500 extends out from the side of the baffle 50, which can accommodate the lifting device 30 and allow the lifting device 30 to pass through. The long side of the "L"-shaped interception groove 500 allows the wire rod hanging rod 41 to pass through, but the width of the long side of the "L"-shaped interception groove 500 is smaller than the diameter of the wire rod. In this way, the lifting device 30 and the hanging device 40 can pass through the interception groove 500, while the wire rod is blocked on one side of the interception groove 500.

[0035] like Figure 5a , Figure 5b and Figure 5c As shown, since a torsion spring is installed between the elastic hinge seat 42 and the end of the lifting device 30, the rod 41 can deflect between the first position and the second position, and can elastically return to the first position from the second position. Therefore, when the rod 41 carrying the rod passes through the blocking baffle 50, since the rod cannot pass through the interception groove 500, the rod 41, the elastic hinge seat 42 and the lifting device 30 can still pass through the interception groove 500. In this way, the rod 41 and the elastic hinge seat 42 will deflect, gradually deflecting from the vertical first position to the horizontal second position. When in the second position, the rod 41 can be pulled out from the middle of the rod, causing the rod to fall off the rod 41. The rod 41 continues to move with the lifting device 30, causing the rod to be intercepted by the blocking baffle 50.

[0036] Furthermore, the flow guide box 60 is fixedly installed below the retaining baffle 50, and the flow guide box 60 is provided with a flow guide plate 61 inside. The flow guide plate 61 is constructed as an inclined plate, with one end of the flow guide plate 61 closer to the retaining baffle 50 being higher than the other end. The turnover box 70 is detachably installed below the flow guide box 60.

[0037] In some embodiments, the guide box 60 is made of stainless steel or alloy and is fixed below the retaining baffle 50. Inside it is an inclined guide plate 61, with the end closer to the retaining baffle 50 being relatively higher. Thus, when the bar is intercepted and falls downward from the retaining baffle 50, it will preferentially fall to the higher side of the guide plate 61 and then roll down along the guide plate 61, entering the turnover box 70 from one side according to a set path. The turnover box 70 is replaced by staff. The turnover box 70 can be of a suitable size as needed to achieve a suitable replacement cycle, saving the frequency of manual replacement and facilitating manual transfer.

[0038] like Figure 2 and Figure 3 As shown, the suspension track 10 includes a track box 11, the top of the track box 11 is provided with a slide rail 100, and the bottom of the track box 11 is provided with a track groove 110. The sliding trolley 20 includes a pair of support wheels 21 that are rolled in the track groove 110. A linkage rod 23 is provided between the pair of support wheels 21, and the linkage rod 23 is slidably disposed in the slide rail 100.

[0039] In some embodiments, the track box 11 is made entirely of stainless steel, and the support wheel 21 is made of a metal wheel, ceramic wheel, or hard plastic wheel with a convex surface, which is intended to reduce the friction between the support wheel 21 and the track box 11. The bottom of the track box 11 is provided with a track groove 110 that cooperates with the support wheel 21. The track groove 110 guides the support wheel 21. The arc surface of the track groove 110 is slightly larger than the arc surface of the support wheel 21. At the same time, a linkage rod 23 extending upward is provided between a pair of support wheels 21. The linkage rod 23 extends upward into the slide rail 100 and can cooperate with the drive wheel 01 to drive the sliding car 20 to move.

[0040] The linkage rod 23 protrudes upward from the slide rail 100. The drive wheel 01 is located above the track box 11. The edge of the drive wheel 01 is provided with multiple centrally symmetrically distributed gear teeth 011. There is a tooth groove 010 between any two adjacent gear teeth 011. The drive wheel 01 is configured to be driven to rotate by the drive shaft 02. When the drive wheel 01 rotates, it meshes with multiple linkage rods 23 in the track box 11 to drive the support wheel 21 to move in the track box 11. The drive shaft 02 is connected to an external drive device (e.g., a motor). The drive shaft 02 drives the drive wheel 01 to rotate, so that the tooth groove 010 on the drive wheel 01 meshes with the linkage rod 23.

[0041] Furthermore, a connecting rod 22 is provided between any two adjacent sets of support wheels 21. The multiple sets of support wheels 21 provided in the track box 11 are linked together through the connecting rod 22, so that the support wheels 21 can be linked together to maintain the connection relationship.

[0042] like Figure 2 As shown, the lifting device 30 includes a first connecting rod 31 and sleeves 32 and a second connecting rod 33 disposed at both ends of the first connecting rod 31. The first connecting rod 31 is constructed as an "L"-shaped rod. The sleeves 32 are sleeved on the top end of the linkage rod 23 and fixed to the first end of the first connecting rod 31. The second connecting rod 33 is horizontally disposed at the second end of the first connecting rod 31. The sleeves 32 at the top end of the first connecting rod 31 are sleeved on the linkage rod 23. When the linkage rod 23 moves, the sleeves 32 sleeved on the linkage rod 23 will move accordingly, thereby driving the first connecting rod 31 to move.

[0043] Furthermore, in order to keep the first link 31 stable during movement, a guide rail 111 is fixedly provided on the outer wall of the track box 11, and a guide rod 34 is fixedly provided on the outer wall of the first link 31 corresponding to the guide rail 111. The guide rod 34 slides in the guide rail 111. By setting the guide rod 34 in the middle section of the first link 31, the guide rod 34 can support the first link 31 and keep the first link 31 stable during movement.

[0044] In conjunction with the above embodiments, by setting a suspension track 10 on the collection path of the wire rod production, and setting a retaining baffle 50, a flow guide box 60, and a turnover box 70 at the wire rod collection point, the worker only needs to place the wound wire rod on the hanger 40 at the lower end of the hanger 30. When the hanger 40 carries the wire rod past the retaining baffle 50, the retaining baffle 50 can cause the wire rod to fall off the hanger 40. The wire rod enters the turnover box 70 in an orderly manner from the flow guide box 60, and the wire rod is automatically collected and processed, which can improve the transfer efficiency and stability, increase the degree of automation, and reduce the intensity of manual labor.

[0045] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0046] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
