The cloth delivery frame 431 is provided with a flip driving member 433 for driving the cloth delivery assembly 432 to rotate relative to one end of the cloth delivery frame 431, so as to overturn the cloth pile delivered to the cloth delivery assembly 432, thereby pulling out the cloth head located at the bottom of the cloth pile. The cloth delivery fence 434 is arranged on both sides of the cloth delivery assembly 432 and one end away from the intermediate conveying device 42. The movable door 435 is movably arranged on the end of the cloth delivery assembly 432 near the intermediate conveying device 42, so as to open the movable door 435 when the cloth pile is input, or close the movable door 435 before overturning the cloth pile. In this embodiment, the movable door 435 is driven by a cylinder to lift and lower to realize the opening or closing function.

[0044] The cloth loosening buffer device 4 cooperates with the cloth-in conveying device 41, the intermediate conveying device 42 and the cloth-out conveying device 43 arranged in sequence along the conveying direction, and the cloth-out conveying device 43 cooperates with the cloth-out machine frame 431, the cloth-out conveying assembly 432, the flip driving member 433, the cloth-out fence 434 and the movable door 435. The grey cloth loosened by the cloth loosening machine 3 is first stacked on the cloth-in conveying device 41 to form a cloth pile, and then transported to the intermediate conveying device 42 for temporary storage. When the cloth pile on the cloth-out conveying device 43 is about to be processed, one of the cloth piles temporarily stored on the intermediate conveying device 42 is transported to the cloth-out conveying device 43, so that the grey cloth shaping machine 5 can continuously process the cloth pile.

[0045] In this embodiment, the cloth inlet conveying device 41, the conveying unit 421 and the cloth outlet conveying assembly 432 are all belt conveyors. The cloth inlet conveying device 41 and the cloth outlet conveying device 43 have substantially the same structure, but the cloth inlet conveying device 41 does not need to realize the flipping function.

[0046] In this embodiment, two grey cloth shaping machines 5 are arranged in parallel. According to actual needs, one or more grey cloth shaping machines 5 may be selected. The grey cloth shaping machine 5 is an existing device for changing the width and weight of the grey cloth by padding various dyes and chemicals for stretching and resin finishing, and will not be described in detail here.

[0047] See also Figure 8 The buffer device 6 for dyeing includes two cloth-carrying turnover box buffer conveyor lines 61, an empty turnover box buffer conveyor line 62 and a connecting conveyor line 63.

The empty turnover box buffer conveyor line 62 is used to store and convey empty turnover boxes 2. The cloth-carrying turnover box buffer conveyor line 61 is used to store and convey turnover boxes 2 containing grey cloth. The two ends of the connecting conveyor line 63 are respectively arranged at the cloth outlet ends of the two grey cloth setting machines 5, so that the grey cloths at the cloth outlet ends of the two setting machines 5 are stacked in the turnover boxes 2 at the two ends of the connecting conveyor line 63. The empty turnover boxes 2 on the empty turnover box buffer conveyor line 62 are transported to both ends thereof through the connecting conveyor line 63 and stop to be stacked with the grey cloth at the cloth outlet of the grey cloth setting machine 5. When the turnover box 2 is full of grey cloth, the grey cloth is cut off so that the turnover box 2 full of grey cloth is transported to the corresponding cloth-carrying turnover box buffer conveyor line 61 for storage, so that the circulating logistics device 8 can take away the turnover box 2 full of grey cloth at the outlet of the cloth-carrying turnover box buffer conveyor line 61.

[0048] As a preferred embodiment, the two cloth-carrying turnover box buffer conveyor lines 61 and the empty turnover box buffer conveyor line 62 are both spliced ​​into a long conveying line using multiple chain conveyors of the prior art. The chain conveyor includes a chain conveyor frame and two conveyor chains rotatably arranged on both sides of the chain conveyor frame. The turnover box 2 is carried on the two conveyor chains for conveyance. It can be understood that the two cloth-carrying turnover box buffer conveyor lines 61 and the empty turnover box buffer conveyor line 62 can also use belt conveyors, roller conveyors or other equipment that can carry the turnover box 2 for conveyance.

[0049] As a preferred embodiment, the connecting conveyor line 63 includes a linear conveyor 631 and a diverting conveyor 632. The same end of the two cloth-carrying turnover box buffer conveyor lines 61 and the empty turnover box buffer conveyor line 62 is connected to a diverting conveyor 632. The diverting conveyor 632 is used to first input the turnover box 2 to the diverting conveyor 632 along the length direction of the turnover box 2, and then output the turnover box 2 to the cloth-carrying turnover box buffer conveyor line 61 along the width direction of the turnover box 2. Two adjacent diverting conveyors 632 are connected by the linear conveyor 631. In this way, it is easy to realize that the empty turnover box 2 on the empty turnover box buffer conveyor line 62 is first moved to the corresponding diverting conveyor 632, and then the empty turnover box 2 is transported to the linear conveyor 631 at the designated end by the diverting conveyor 63, and then the empty turnover box 2 is transported to the diverting conveyor 632 at the designated end by the linear conveyor 63, so as to be loaded with the grey cloth at the cloth outlet end of the grey cloth setting machine 5.

[0050] Preferably, the linear conveyor 631 is a roller conveyor, and the turning conveyor 632 is a lifting and transferring machine, but it is not limited to this type of conveyor.

[0051] In order to facilitate the placement of turnover boxes 2 at the cloth inlet end of the dyeing machine 7 and save space, the chain conveyor at the output end of each cloth-carrying turnover box buffer conveyor line 61 and the empty turnover box buffer conveyor line 62 is provided with a lifting and rotating mechanism 64, which is arranged between the two conveying chains of the chain conveyor to lift the turnover boxes 2 on the two conveying chains and carry the turnover boxes 2 to rotate 90 degrees. The lifting and rotating mechanism 64 includes a 90-degree angle cylinder and a bearing platform fixed to the piston rod end of the 90-degree angle cylinder. The bearing platform is driven by the 90-degree angle cylinder to rise and abut against the bottom of the turnover box 2, and the turnover box 2 is lifted off the two conveying chains, and then the bearing platform is driven by the 90-degree angle cylinder to rotate 90 degrees, thereby completing the turning of the turnover box 2.

[0052] See also Fig. 9 The dyeing machine 7 is a machine that dyes the grey cloth with the desired color by adding dye additives. In this embodiment, the dyeing machines 7 are arranged in two rows, and each row is provided with a plurality of dyeing machines 7 of different numbers for combined use, and each row of dyeing machines 7 is connected to form a corridor. Stairs 71 are set up at both ends of each row of dyeing machines 7 to facilitate workers to enter and operate. The cloth inlet end of each dyeing machine 7 is close to the circulating logistics device 8 to facilitate the delivery of grey cloth and the removal of dyed cloth (dyed cloth is the cloth dyed by the dyeing machine 7).

[0053] See also Fig.10, the solid arrow in the figure indicates the conveying direction of the turnover box 2 carrying the grey cloth or dyed cloth, and the dotted arrow in the figure indicates the conveying direction of the empty turnover box 2. The circulating logistics device 8 includes a conveying loop 81, an outer conveying line 82 and an inner conveying line 83. The conveying loop 81 surrounds the outer periphery of the two rows of dyeing machines 7, and the conveying loop 81 is used to cyclically and intermittently convey the turnover box 2 along the conveying loop 81. The outer conveying line 82 is arranged on the outer side of the conveying loop 81 and is located between the conveying loop 81 and the output end of the buffer device 6 to be dyed. The outer conveying line 82 is used to convey the turnover box 2 carrying the grey cloth on the cloth-carrying turnover box buffer conveying line 61 of the buffer device 6 to be dyed to the conveying loop 81, and to convey the empty turnover box 2 on the conveying loop 81 to the empty turnover box buffer conveying line 62. The inner conveying line 83 is arranged on the inner side of the conveying loop 81 and is located between the conveying loop 81 and the cloth inlet end of each row of dyeing machines 7. The inner conveying line 83 is used to convey the turnover box 2 carrying the grey cloth on the conveying loop line 81 to the designated cloth inlet end of the dyeing machine 7, to convey the empty turnover box 2 after the grey cloth is introduced into the dyeing machine 7 and the turnover box 2 carrying dyed cloth at the dyeing machine 7 to the conveying loop line 81, and to convey the empty turnover box 2 on the conveying loop line 81 to the cloth outlet end of the dyeing machine 7 (the cloth outlet end is the same end as the cloth inlet end). The empty turnover box 2 on the conveying loop line 81 is conveyed to the empty turnover box buffer conveying line 62 through the outer conveying line 82 for recycling. The turnover box 2 carrying dyed cloth on the conveying loop line 81 is finally conveyed to the water pressure buffer device 9 and enters the next process.

[0054] The conveying loop 81 adopts a square conveying mechanism, and the outer conveying line 82 and the inner conveying line 83 are respectively arranged in parallel on the outer side and the inner side of one side of the square conveying mechanism. The length of the outer conveying line 82 is smaller than the length of the corresponding side of the square conveying mechanism, which is convenient for arranging the water pressure buffer device 9 on the outer side of the corresponding side of the square conveying mechanism. The length of the inner conveying line 83 is equivalent to the length of the corresponding side of the square conveying mechanism, so as to facilitate the transportation of the turnover box 2 with the dyeing machine 7. As a preferred embodiment, the square conveying mechanism is spliced ​​by multiple chain conveyors, and the four corners of the square conveying mechanism and the connection with the water pressure buffer device 9 are all equipped with a lifting and transferring machine for steering transportation. Preferably, the square conveying mechanism adopts a rectangular conveying mechanism, and the outer conveying line 82 and the inner conveying line 83 are respectively arranged in parallel on the outer side and the inner side of the long side section of the rectangular conveying mechanism, so as to facilitate the overall layout.

[0055] As a preferred embodiment, the outer transport line 82 includes a transport ground rail 821 and a transport forklift 822 slidably disposed on the transport ground rail 821. The transport forklift 822 has a fork that can be extended to both sides of the transport ground rail 821, and the fork can be raised and lowered on the transport forklift 822. The transport forklift 822 slides along the transport ground rail 821, and the telescopic and lifting actions of the fork are coordinated to realize the transfer of the turnover box 2 between the cloth-carrying turnover box buffer conveyor line 61 and the empty turnover box buffer conveyor line 62 and the conveying loop line 81. Similarly, the inner transport line 83 can also adopt the same embodiment as the outer transport line 82, which will not be repeated here.

[0056] The method for using the circulating logistics device 8 includes the following steps: the outer conveying line 82 takes out the turnover boxes 2 carrying the grey cloth from the output end of the cloth-carrying turnover box buffer conveying line 61 box by box, and conveys the turnover boxes 2 carrying the grey cloth to the conveying loop line 81 for intermittent conveying during the intervals when the conveying loop line 81 stops conveying. When the turnover boxes 2 carrying the grey cloth are conveyed to the range available for conveying on the inner conveying line 83 (i.e., the long side section of the rectangular conveying mechanism), the inner conveying line 83 takes out the turnover boxes 2 carrying the grey cloth on the conveying loop line 81 and conveys them to the designated cloth inlet end of the dyeing machine 7, and conveys the empty turnover boxes 2 formed after all the grey cloth in the turnover boxes 2 at the cloth inlet end of the dyeing machine 7 is input into the dyeing vat of the dyeing machine 7 to the conveying loop line 81. When the plurality of empty turnover boxes 2 on the conveying loop 81 pass through the conveying range of the outer conveying line 82, the outer conveying line 82 conveys a part of the empty turnover boxes 2 to the empty turnover box buffer conveying line 62, and the rest of the empty turnover boxes 2 continue to be intermittently conveyed along the conveying loop 81. When the dyed cloth formed after the dyeing machine 7 dyes the grey cloth needs to be taken out from the dyeing vat of the dyeing machine 7, the empty turnover boxes 2 on the conveying loop 81 are conveyed to the cloth outlet end of the dyeing machine 7 through the inner conveying line 83 for storing the dyed cloth taken out from the dyeing vat of the dyeing machine 7. When the dyed cloth is stacked in the turnover box 2, the inner conveying line 83 conveys the turnover box 2 with the dyed cloth to the conveying loop 81. When the conveying loop line 81 carries the turnover box 2 containing dyed cloth and passes through the water pressure buffer device 9, it is conveyed to the water pressure buffer device 9. After the dyed cloth is taken out from the water pressure buffer device 9, the empty turnover box 2 is conveyed to the conveying loop line 81. When the conveying loop line 81 carries the empty turnover box 2 and passes through the conveying range of the inner conveying line 83, the empty turnover box 2 on the conveying loop line 81 is conveyed to the empty turnover box cache conveying line 62. In this way, a circular conveyance of grey cloth from the outer conveying line 82 → conveying loop line 81 → inner conveying line 83 → the cloth inlet end of the dyeing machine 7, a circular conveyance of dyed cloth from the cloth outlet end of the dyeing machine 7 → inner conveying line 83 → conveying loop line 81 → water pressure buffer device 9, a circular conveyance of empty turnover boxes 2 from the water pressure buffer device 9 and the cloth inlet end of the dyeing machine 7 → conveying loop line 81 → outer conveying line 82 → the empty turnover box buffer conveying line 62, and a circular conveyance of empty turnover boxes 2 from the water pressure buffer device 9 and the cloth inlet end of the dyeing machine 7 → conveying loop line 81 → inner conveying line 83 → the cloth outlet end of the dyeing machine 7 are formed. In this way, it is easy to realize the input of grey cloth and output of dyed cloth for multiple dyeing machines 7, and the efficient connection of logistics between the grey cloth setting machine 5 and the water pressure machine 10, which greatly improves the logistics transportation efficiency and provides the best implementation plan for setting up a large-scale, efficient and intelligent dyeing and finishing factory. In addition, the circulating logistics device 8 has a reasonable structural layout and can cache the grey cloth and dyed cloth, thereby reducing the space occupied by the dyeing cache device 6 and the pressurized water cache device 9, improving the space utilization rate of the dyeing and finishing workshop, and facilitating the compact layout of various equipment in the dyeing and finishing workshop.

[0057] In this embodiment, three sets of water pressure buffer devices 9 are arranged in parallel to connect three sets of water pressurizers 10 to perform water pressure process. The water pressure buffer device 9 can adopt the same structure as the buffer device 6 to be dyed. The water pressure buffer device 9 includes two dyed cloth buffer lines 91, an empty box buffer line 92 and an end conveying line 93. The two dyed cloth buffer lines 91 are arranged in parallel on both sides of the empty box buffer line 92, and the end conveying line 93 is arranged at the same end of the two dyed cloth buffer lines 91 and the empty box buffer line 92, forming an E-shaped conveying line. The input end of the water pressure buffer device 9 is connected to the conveying loop 81 of the circulating logistics device 8, so that the turnover boxes 2 loaded with dyed cloth on the conveying loop 81 are transported to the two dyed cloth buffer lines 91 according to the color of the dyed cloth, and the empty turnover boxes 2 after the dyed cloth is taken from the dyed cloth buffer line 91 are transported to the conveying loop 81 along the empty box buffer line 92, and then transferred to the empty turnover box buffer conveying line 62 through the outer conveying line 82 outside the conveying loop 81. In this way, the smooth operation of a series of logistics, such as the input of the grey cloth of the dyeing machine 7, the output of the dyed cloth after the dyeing machine 7 is processed, and the recycling of the empty turnover boxes 2, can be ensured, effectively improving the logistics transportation efficiency of the cloth in and out of the dyeing machine 7, greatly reducing the number of workers, reducing the labor intensity of workers, subverting the production mode of the traditional dyeing and finishing industry, and facilitating the intelligent and standardized production of the dyeing and finishing industry.

[0058] As a preferred embodiment, the water pressure buffer device 9 and the dyeing buffer device 6 are both connected to the outside of the same side of the square conveying mechanism, which is beneficial to the spatial layout of various equipment in the entire production workshop. The overall layout structure is in a U-shape, which shortens the length of the production line, and makes the grey cloth storage device 1 and the finished product storage device 14 located on the same side of the production workshop, which is convenient for logistics transportation.

The transverse inbound conveyor line 145 extends along the width direction of the finished product shelf 141 to the outside of the finished product shelf 141 for conveying along the width direction of the finished product shelf 141. The input end of the inbound transition conveyor line 143 is close to one side of the transverse inbound conveyor line 145, so that the turnover box 2 containing finished cloth on the transverse inbound conveyor line 145 is conveyed to the inbound transition conveyor line 143, so that the inter-warehouse conveyor line 142 can take away the turnover box 2 containing finished cloth on the inbound transition conveyor line 143. The longitudinal inbound conveyor line 146 extends from the input end of the transverse inbound conveyor line 145 along the length direction of the finished product shelf 141, so as to convey the turnover box 2 containing finished cloth along the length direction of the finished product shelf 141. The longitudinal storage conveyor line 146 is arranged vertically to the transverse storage conveyor line 145, so as to facilitate the turning and conveying of the turnover box 2 carrying the finished cloth and facilitate the spatial layout. The empty box return conveyor line 147 is arranged in parallel to the side of the longitudinal storage conveyor line 146 away from the finished product shelf 141, and multiple sorting conveyors 148 are arranged on both sides of the empty box return conveyor line 147, so that the finished cloth falling during sorting can be stacked in the turnover box 2 on the sorting conveyor 148 away from the side of the longitudinal storage conveyor line 146, and the turnover box 2 carrying the finished cloth is sequentially conveyed to the empty box return conveyor line 147, the sorting conveyor 148 close to the side of the longitudinal storage conveyor line 146, and the longitudinal storage conveyor line 146.

The six sorting conveyors 148 are continuously arranged away from one side of the longitudinal warehousing conveyor line 146. The six continuously arranged sorting conveyors 148 are preferably equipped with a lifting and transferring machine of the prior art to carry the turnover box 2 for corner conveying, but are not limited to the lifting and transferring machine.Every two of the six sorting conveyors 148 form a group. One sorting conveyor 148 in each group is used to place a turnover box 2 for carrying the finished cloth unloaded from the unloading device 138, and the other sorting conveyor 148 is used to place a spare turnover box 2, so that when the turnover box 2 on the sorting conveyor 148 in the group is full of finished cloth and transported out, the spare turnover box 2 is transported in for the next box of finished cloth to be loaded. The empty box return conveyor line 147 is used to transport the empty turnover box 2 to the sorting conveyor 148 on the side away from the longitudinal storage conveyor line 146. Specifically, a sorting conveyor 148 is set directly below each unloading device 138 to classify and store the finished cloth on the corresponding sorting conveyor 148. One side of the transverse outbound conveyor line 149 is arranged near the output end of each outbound transition conveyor line 144, so that the turnover box 2 carrying the finished cloth on each outbound transition conveyor line 144 can be conveyed to the transverse outbound conveyor line 149.

[0064] The working principle of the finished product storage device 14 is as follows: the empty turnover boxes 2 are stored in a section of the empty box return conveyor line 147 close to the horizontal outbound conveyor line 149. The empty turnover boxes 2 are transported to each sorting conveyor 148 on the side away from the longitudinal inbound conveyor line 146 through the empty box return conveyor line 147. The unloading device 138 of the sorting device 13 classifies the finished cloth and stores it in the turnover boxes 2 on the corresponding sorting conveyor 148. When the finished cloth stored in the turnover box 2 reaches a specified amount (for example, ten rolls of finished cloth are placed in each box), the turnover box 2 containing the finished cloth is transported to the longitudinal inbound conveyor line 146 through the sorting conveyor 148 on the side away from the longitudinal inbound conveyor line 146, the empty box return conveyor line 147, and the sorting conveyor 148 on the side close to the longitudinal inbound conveyor line 146 in sequence.

The horizontal inbound conveyor line 145 conveys the turnover box 2 carrying the finished cloth to the corresponding inbound transition conveyor line 143. The inter-warehouse conveyor line 142 takes the turnover box 2 carrying the finished cloth on the inbound transition conveyor line 143 and stores it on the finished product shelf 141. When loading is required, the turnover box 2 carrying the finished cloth on the finished product shelf 141 is taken out through the inter-warehouse conveyor line 142 and placed on the outbound transition conveyor line 144. The turnover box 2 carrying the finished cloth is transferred to the horizontal outbound conveyor line 149 through the outbound transition conveyor line 144. The horizontal outbound conveyor line 149 conveys the turnover box 2 carrying the finished cloth to the outbound transfer machine 140, and conveys the turnover box 2 carrying the finished cloth to the outbound transfer machine 140. After the finished cloth in the turnover box 2 on the outbound transfer machine 140 is removed, the empty turnover box 2 is transported to the empty box return conveyor line 147 through the transverse outbound conveyor line 149 for recycling. In this way, the empty turnover box 2 is first transported to the sorting conveyor 148 below the unloading device 138 of the sorting device 13, and the turnover box 2 filled with finished cloth is successively transported to the empty box return conveyor line 147, the sorting conveyor 148 near the side of the longitudinal inbound conveyor line 146, the longitudinal inbound conveyor line 146, the transverse inbound conveyor line 145, the inbound transition conveyor line 143, the inter-warehouse conveyor line 142, the outbound transition conveyor line 144, the transverse outbound conveyor line 149 and the outbound transfer machine 140.
