Description

Technical Field

[0001] The invention relates to a material lifting and transmission system used in a thin network, belonging to the field of automated mechanical equipment. Background Art

[0002] Fine winding connection is the mechanical equipment system connecting the spinning frame and the winding machine. Limited by the working efficiency of the spinning frame, it usually takes more than 2, or even 3 to 5 spinning frames to correspond to and meet the working efficiency of a winding machine. In the early production process of the spinning mill, workers mainly collected the spinning tubes and then transported them to the corresponding winding machine area for winding. This process requires strict registration and management to prevent corresponding transportation errors and affect production. The specifications of fine yarn products involve parameters such as color and count. It is difficult to identify fine yarn products of the same color and different counts with the naked eye. Therefore, in order to prevent errors, strict numbering is required, and circulation, storage and transportation records are kept, which consumes a lot of manpower and material resources.

[0003] In order to improve production efficiency and reduce the risk of material confusion during storage and transportation, a special "fine-link" equipment was developed to establish a "fine-link" between multiple spinning machines and multiple winding machines.

[0004] At present, there are some interconnected solutions on the market, such as a interconnected conveying system with Chinese patent publication number CN104846492A or Chinese patent publication number CN204608276U, which uses the relatively mature AGV intelligent car technology to set up several AGV cars between the spinning machine working group and the winding machine working group, and uses wireless remote control devices and wireless scheduling devices to coordinate and control the AGV cars. However, such an AGV car intelligent transportation system mainly relies on the development of AGV control technology, and has high use and maintenance costs. In addition, the AGV car moves on the ground, occupying the floor space of the workshop, which will affect the daily maintenance work of workers in the workshop. The AGV car also needs to be charged and maintained, and needs to be over-configured to meet the usage needs.

[0005] There is also a fine-linked tube yarn conveying device with Chinese patent publication number CN207987402U, a fine-linked tube yarn conveying device and conveying method with Chinese patent publication number CN108301079A, a fine-linked tube yarn conveying system and conveying method with Chinese patent publication number CN110386506A, a fine-linked tube yarn conveying system and conveying method with Chinese patent publication number CN110396738A, and a fine-linked tube yarn and bobbin conveying interface device and conveying method with Chinese patent publication number CN108560088A, and a fine-linked tray operating device with Chinese patent publication number CN201236242Y. A series of fine-linked solutions are disclosed, but more of the overall connection method and system operation method are introduced, and the specific transportation mechanism solution is not involved.

[0006] There is also a conveying interface device for fine-linked tube yarn and bobbin and a conveying method thereof with Chinese patent publication number CN108560088A, and a conveying interface device for fine-linked tube yarn and bobbin with Chinese patent publication number CN207877969U, which discloses some specific details of fine-linked equipment, but adopts a relatively complex single-spindle conveying method, with low conveying efficiency, and the output interval of a single spindle of the spinning machine is very short, requiring a high-frequency switching channel of the fine-linked machine to meet the operation of the entire system.

[0007] In order to meet the production needs of spinning mill workshops, it is necessary to conduct further research on the fine-winding connection between spinning machines and winding machines, in order to break through the fine-winding connection technology, especially the group-to-group fine-winding connection system, because the connecting track of the group-to-group connection mode enables the spinning machine and the winding machine to be connected, and the production capacity of the winding machine can be universal for the whole group. Therefore, the number of spindles of each spinning machine and winding machine can be reasonably selected without affecting the production capacity matching of the fine winding.

[0008] The entire interconnected system includes the design of the track conveying system, the design of the material lifting and transmission system, and the design of the whole machine control system. This application focuses on the research of the material lifting and transmission system. Summary of the invention

[0075] In the present system, the main conveying track and the branch conveying track are both in the form of hanging rails, fixed above the winding machine group and the spinning machine group, and do not occupy ground space.

[0076] The spun yarn produced by the spun yarn machines in the spun yarn machine group is first transported to the turnover basket located at the end of the spun yarn machine. After the turnover basket is full, the turnover basket is lifted by the lifting system I, and the turnover basket is transferred to the branch conveying track by the conveying hanger. Driven by the driving device, the turnover basket passes through several forked tracks II and finally arrives at the main conveying track to be transported in the direction of the winding machine group.

[0077] The branch conveying track in the winding machine group is also provided with several forked tracks II. According to the system requirements, the corresponding turnover baskets filled with spun yarn are transferred to the corresponding ends of the winding machines, and the turnover baskets are lowered to the feed port of the winding machine by the lifting system I and dumped into the winding machine to complete the feeding operation.

[0078] The empty tubes output by the winding machine after winding is completed return to the empty turnover basket, and are transferred to the branch conveying track in the winding machine group by the lifting system I, and finally return to the empty tube conveying track of the main conveying track, and the empty tubes are transported back to the corresponding spinning frame for use in the operation of the spinning frame.

[0079] In the system, a full-basket storage area for spun yarn is also provided, and the full-basket storage area for spun yarn is arranged close to the winding machine group.

[0080] In this system, an empty tube and full basket storage area is also provided, and the empty tube and full basket storage area is arranged close to the spinning frame group. When the waiting area of ​​the spinning frame is relatively full, the turnover basket full of empty tubes can be temporarily stored in the empty tube and full basket storage area.

[0081] The turnover basket is provided with a special identity tag, such as a barcode, a QR code, or an RFID card, etc., and a plurality of reading devices are provided on the main conveying track or the branch conveying track. By reading the identity tag on the passing turnover basket, the state of the adjacent forked track is adjusted, and then the driving device drives the turnover basket to continue moving forward and finally reach the designated working position. By using the identity tag, the turnover basket and the materials therein can be distinguished one by one from each other, effectively saving the storage memory of the system.

[0128] 3. Forked Track Components

[0129] like Figure 22 to Figure 24 As shown, this is a schematic diagram of the structure of the bifurcated track II of this system.

[0130] According to the track system setting, there are many forked tracks that split into two. As shown in the figure, the main track 201 needs to be forked into a first branch track 202 and a second branch track 203; a track change component needs to be set between the main track 201 and the two forked tracks (i.e., the first branch track 202 and the second branch track 203).

[0131] The track change assembly includes a straight track 211, an S-shaped curved track 212, a track mounting plate 213, an assembly fixing plate 214, and a track change driving element.

[0132] The straight track 211 and the S-shaped curved track 212 are fixed on the track mounting plate 213; the track mounting plate 213 is fixed on the component fixing plate 214 through the track change driving element, and the component fixing plate 214 is used to fix the entire track change component.

[0133] In this embodiment, the track change driving element is a pneumatic track change driving element, including a track change driving cylinder 215; the track change driving cylinder 215 is a flat cylinder, and its cylinder body is fixed to the track mounting plate 213; the piston rod of the track change driving cylinder 215 is fixed to the component fixing plate 214. The track switching can be realized by driving the track change driving cylinder 215.

[0134] Furthermore, the track change driving element may also include a track change guide rod 216 and a track change slider 217. Both ends of the track change guide rod 216 are fixed on the component fixing plate 214, on which a track change slider 217 is sleeved, and the track change slider 217 is fixed on the track mounting plate 213. By providing the track change guide rod 216 and the track change slider 217, the track change switching process can be smoother and more stable.

[0135] The track-changing driving element may also adopt a driving system such as a linear electric cylinder, a connecting rod mechanism, etc.

[0136] In this system, the hoisting frame is not provided with a travel drive mechanism, but friction wheels are arranged at intervals on the hanging rails, and the hoisting frame is driven by the friction wheels to realize the movement of the hoisting frame on the hanging rails.
