Abstract
Description
Technical Field
[0001] This utility model relates to the field of doffing machine technology, specifically to a modified layout combination device for a double automatic doffing machine. Background Technology
[0002] A doffing machine is a piece of equipment used in the textile industry, primarily for doffing roving. Roving typically refers to the fiber bundles processed by equipment such as spinning machines or carding machines during the spinning process. These fiber bundles need to be doffed before further processing, in order to facilitate the subsequent spinning process.
[0003] In older factory buildings, doffing machines are typically semi-automatic, lacking pick-and-place units and circular conveyor structures; for example... Figure 6 The image shows a conventional doffing machine, which mainly consists of a spinning body 01 on which multiple yarn tubes 02 are placed. The spinning process involves placing empty yarn tubes 02 onto the lower rib support plate 03 of the spinning body 01, and then winding yarn around them. This process is existing technology and will not be described in detail here. However, this type of equipment cannot centrally and neatly transfer the yarn tubes 02; that is, it lacks a proper transfer track to move the yarn tubes one by one to the next workstation or transport them from upstream workstations.
[0004] After modification, a picking unit and a ring conveying structure can be set up. The picking unit is used to remove the yarn tube 02 on the support plate 03 or place new yarn tubes. The ring conveying structure is used to transport the yarn tubes, that is, to transfer them to another position for storage, or to move empty yarn tubes to a position close to the picking unit. However, in the old factory, the interval between two doffing machines is usually 1.5 meters to 2 meters, while the ring conveying structure is a ring structure with a coverage length of 2 meters to 2.5 meters. When two sets of ring conveying structures are placed on the same side, the space is too small to accommodate them. That is, the two sets of ring conveying structures cannot be set up because they will touch each other. Utility Model Content
[0005] The main objective of this invention is to provide a technique for reducing space usage by improving the layout.
[0006] To achieve the above objectives, this utility model provides a modified layout combination device for dual automatic doffing machines, including a first doffing machine and a second doffing machine;
[0007] The first doffing machine has a first spinning main unit, a first take-up unit and a first annular conveying structure. The first spinning main unit is used for the yarn tube spinning process. The first take-up unit is located on the upper side of the first spinning main unit. The first annular conveying structure is arranged on the side of the first take-up unit.
[0008] The second doffing machine has a second spinning main unit, a second take-up unit, and a second annular conveying structure.

The second annular conveying structure is arranged on the side of the second take-up unit, and the first annular conveying structure and the second annular conveying structure are located at diagonal positions on both sides.
[0009] The aforementioned beneficial effects are that by arranging the two circular conveyor structures diagonally and staggering them, space is utilized efficiently.

[0012] A preferred embodiment is that the lower end of the guide rail is provided with a slot, and multiple mobile trolleys are arranged in the slot. Two mobile trolleys form a group, and the lower ends of every two mobile trolleys are rotatably connected to both ends of the hanging plate. The lower end of the hanging plate is provided with multiple lifting components.
[0013] A preferred embodiment is that the first and second annular transport structures are generally in a right-angle curved shape, and the first and second annular transport structures have a first extension section and a second extension section.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0024] Example 1:
[0025] like Figures 1 to 3 As shown, this utility model provides a modified layout combination device for dual automatic doffing machines, including a first doffing machine 10 and a second doffing machine 20;
[0026] The first doffing machine 10 has a first spinning main unit 11, a first picking unit 12 and a first annular conveying structure 13. The first spinning main unit 11 is used for the yarn tube spinning process. The first picking unit 12 is located on the upper side of the first spinning main unit 11. The first annular conveying structure 13 is arranged on the side of the first picking unit 12.
[0027] The second doffing machine 20 has a second spinning main unit 21, a second take-up unit 22, and a second annular conveying structure 23. The second doffing machine 20 is arranged side by side with the first doffing machine 10, and a walking channel 5 is formed between the second doffing machine 20 and the first doffing machine 10. The second spinning main unit 21 is used for the yarn tube spinning process. The second take-up unit 22 is located on the upper side of the second spinning main unit 21. The second annular conveying structure 13 is arranged on the side of the second take-up unit 22, and the first annular conveying structure 13 and the second annular conveying structure 23 are respectively located at diagonal positions on both sides.
[0028] The spinning process of the first spinning main unit 11 and the second spinning main unit 21 for the yarn tube is existing technology and will not be described in detail here.
[0029] Here, by arranging the two circular conveyor structures diagonally and staggering them, space is made more efficient. Especially in small spaces, it is easy to place the two improved doffing machines. By improving the layout of the two doffing machines, the area occupied is greatly reduced.
[0030] In the specific working process, after the spinning main unit completes spinning on the yarn tube, the lifting frame 31 descends, and multiple picking pieces 32 remove the spun yarn tube from the spinning main unit. The removal can be achieved by the picking pieces 32 directly clamping and fixing the yarn tube on the support plate 03, i.e., the lifting frame 31 lowers the picking pieces 32 to a specific position and then removes the yarn tube; or by personnel taking the yarn tubes and placing them on the picking pieces 32 for hoisting. This achieves the process of quickly transferring the yarn tubes to the picking pieces 32. This allows for the one-by-one placement and transport of the yarn tubes, facilitating the transport of the yarn tubes (after spinning) as a whole to the next workstation, or transferring empty yarn tubes from the previous workstation to the support plate for spinning.
[0031] Then the lifting frame 31 rises, and then the personnel transfer the yarn tube on the pick-up piece 32 to the hanging rail 41, and then transport it away through the hanging rail 41. The conversion can be completed by personnel assistance or by the equipment, that is, the yarn tube conversion is achieved between the pick-up piece 32 and the hanging rail 41.
[0032] Example 2:
[0033] Preferably, both the first picking unit 12 and the second picking unit 22 include a lifting frame 31 and a picking component 32. The lifting frame 31 has a lifting function, and the lifting drive method is, for example, a hydraulic cylinder, a pneumatic cylinder, a chain-type lifting drive, or an existing lifting device to achieve the lifting drive. The lifting frame 31 drives the picking component 32 to lift. The picking component 32 is an existing clamping structure or clamping structure used for temporarily fixing the yarn tube.
[0034] The first annular conveying structure 13 and the second annular conveying structure 23 both include a guide rail 41, and the upper end of the guide rail 41 is connected to the frame of the spinning body through the first connecting block 42 and the second connecting block 43, respectively.
[0035] Example 3
[0036] Preferably, a conversion structure is provided between the lifting frame 31 and the first annular conveying structure 13 or the second annular conveying structure 23. The conversion structure is used to convert the yarn tube between the picking member 32 and the guide rail 41, and the guide rail 41 is used for conveying the yarn tube.
[0037] After the spinning main unit completes spinning on the yarn tube, the lifting frame 31 descends, and multiple picking parts 32 remove the spun yarn tube from the spinning main unit. Then, the lifting frame 31 rises, and through the action of the conversion structure, the spun yarn tube is transferred to the hanging rail 41, so that multiple yarn tubes are transferred one by one to the hanging rail 41 and transported away by the hanging rail 41. Then, the hanging rail 41 transports the empty yarn tubes back to the lifting frame 31, and through the action of the conversion structure again, the empty yarn tubes are transferred one by one to the multiple picking parts 32, and spinning operations can be carried out again.
[0038] The conversion structure is an existing technology, such as using a robotic arm to grab the yarn tube on the pick-up part 32 and transfer it to the position of the hanging rail 41 for clamping and fixing.
[0039] The following is a specific conversion structure of this utility model, such as... Figure 7 As shown, the conversion structure is located between the first picking unit 12 (second picking unit 22) and the hanging rail 41, and has a rotating support base 50. The rotating support base 50 has a telescopic arm 51, and the outer end of the telescopic arm 51 has a clamping hand 52.
[0040] In practical applications, the telescopic arm 51 can be adjusted in length as needed, and can be switched between the two sides by rotating the support base 50. This allows the yarn tube 02 to be clamped and fixed below the first picking unit 12, and then transferred to the other side and fixed below the hanging rail 41. This completes the conversion.
[0041] Preferably, such as Figure 8 As shown, a conveying assembly is located below the lifting frame 31. The conveying assembly has a conveying wheel 55, on which a conveying chain 56 or belt is fitted. A picking component 32 is located below the conveying chain 56. Multiple picking components 32 move with the conveying chain 56, so that after moving to a specific position, the yarn tube can be switched through the conversion structure above. That is, the multiple picking components 32 below the lifting frame 31 are arranged in a circular moving manner. Through circular movement, the yarn tube at each position can be moved to a specific position, which facilitates the conversion through the conversion structure.
[0042] Example 4:
[0043] Preferably, a common rod 61 is provided between one side of the first doffing machine 10 and the second doffing machine 20. Two connecting rods 62 are respectively provided at the upper end of the common rod 61, and the outer ends of the two connecting rods 62 are respectively connected to the frames of the first doffing machine 10 and the second doffing machine 20. This structural design saves materials and reduces costs.
[0044] Preferably, the lower end of the guide rail 41 is provided with a slot 71, and a plurality of mobile trolleys 72 are provided in the slot 71. The mobile trolleys 72 move by means of electric drive, for example. Two mobile trolleys 72 form a group, and the lower ends of every two mobile trolleys 72 are rotatably connected to both ends of the hanging plate 73. The lower end of the hanging plate 73 is provided with a plurality of lifting parts 74.
[0045] The trolley 72 moves the hanging plate 73, which in turn causes multiple lifting components 74 to lift the yarn tube one by one. The specific structure of the lifting component 74 is existing technology, namely, the existing clamping structure or clamping structure.
[0046] Preferably, the first annular transport structure 13 and the second annular transport structure 23 are generally in a right-angle curved shape, and the first annular transport structure 13 and the second annular transport structure 23 have a first extension section 25 and a second extension section 26. The first extension section 25 is located close to the first picking unit 12 or the second picking unit 22, and the second extension section 26 is located away from the first picking unit 12 or the second picking unit 22. The first extension section 25 is located on one side of the end of the frame, and the second extension section 26 is located on the side of the frame.
[0047] The yarn tubes are exchanged at the first extension section 25, and at the second extension section 26, these yarn tubes (full yarn tubes) are stored in the downstream process or received from the upstream process (empty yarn tubes).
[0048] Preferably, the lower rib plate support plate 03 is connected to a horizontal dragging mechanism, that is, the lower rib plate support plate 03 is moved horizontally by means of a hydraulic cylinder, pneumatic cylinder, or lead screw control, so that when it is necessary to pick up or place the yarn tube, the support plate 03 can better correspond with the picking part 32 at the upper position.
[0049] It should be noted that the doffing machine in this embodiment is a mature piece of equipment in the prior art. The structure and working process not specifically described are all recorded in the prior art, and will not be discussed in detail here.
[0050] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
