The finished product shelf is used for storing turnover boxes filled with finished cloth. An in-warehouse conveying line is arranged between every two rows of the finished product shelves and extends along the length direction of the finished product shelf to load and unload goods for the finished product shelf. The incoming warehouse transition conveying line and the outgoing warehouse transition conveying line are respectively arranged at both ends of the in-warehouse conveying line. The transverse incoming warehouse conveying line extends along the width direction of the finished product shelf to the outside of the finished product shelf for conveying along the width direction of the finished product shelf. One side of the input end of the incoming warehouse transition conveying line is close to the transverse incoming warehouse conveying line. The longitudinal incoming warehouse conveying line extends along the length direction of the finished product shelf from the input end of the transverse incoming warehouse conveying line for conveying the turnover box loaded with finished cloth along the length direction of the finished product shelf. The empty box return conveying line is arranged in parallel on the side of the longitudinal incoming warehouse conveying line far from the finished product shelf. Sorting conveyors are arranged on both sides of the empty box return conveying line. One side of the transverse outgoing warehouse conveying line is close to the output end of the outgoing warehouse transition conveying line. The transverse outgoing warehouse conveying line extends along the width direction of the finished product shelf. An outgoing warehouse transfer machine is arranged at one end of the transverse outgoing warehouse conveying line. The other end of the transverse outgoing warehouse conveying line extends to the input end of the empty box return conveying line.

[0006] Further, a plurality of sorting conveyors on the side close to the longitudinal incoming warehouse conveying line are arranged at intervals, and a plurality of sorting conveyors on the side far from the longitudinal incoming warehouse conveying line are arranged continuously.

[0007] Further, the sorting conveyors arranged at intervals adopt chain conveyors, and the continuously arranged sorting conveyors adopt lifting transfer machines.

[0008] Further, the inter-store conveyor line includes an inter-store ground rail and an inter-store stacker. The inter-store ground rail is fixed to the ground and located between two rows of finished product shelves. The inter-store stacker is slidably arranged on the inter-store ground rail. The inter-store stacker has forks that can extend and retract to both sides and can be lifted, so that the turnover box can be carried on the forks for handling.

[0009] Further, both the inbound transition conveyor line and the outbound transition conveyor line adopt roller conveyors.

[0010] Further, the lateral inbound conveyor line includes a lateral ground rail fixed to the ground and extending along the width direction of the finished product shelves, and a lateral transfer vehicle slidably arranged on the lateral ground rail. The lateral transfer vehicle is provided with a transfer mechanism for conveying along the width direction and the length direction of the turnover box.

[0011] Further, the longitudinal inbound conveyor line includes a longitudinal ground rail fixed to the ground and extending along the length direction of the finished product shelves, and a longitudinal transfer vehicle slidably arranged on the longitudinal ground rail. The longitudinal transfer vehicle is provided with a chain conveyor mechanism.

[0012] Further, the empty box return conveyor line includes a chain conveyor section and a lifting transfer section. The chain conveyor section is spliced by a plurality of chain conveyors, and the lifting transfer section is spliced by a plurality of lifting transfer machines.

[0013] Further, the lateral outbound conveyor line includes a slide rail fixed to the ground and extending along the width direction of the finished product shelves, and a lateral outbound vehicle slidably arranged on the slide rail. The lateral outbound vehicle is provided with a chain transmission mechanism.

[0014] A method for using the above-mentioned finished product storage device includes the following steps: The empty turnover boxes are stored on a section of the empty box return conveyor line close to the horizontal outbound conveyor line. The empty turnover boxes are conveyed by the empty box return conveyor line to each sorting conveyor on the side far from the longitudinal inbound conveyor line. The finished cloth is classified and stored in the turnover boxes on the corresponding sorting conveyors by the sorting device. When the amount of finished cloth stored in the turnover box reaches the specified quantity, the turnover boxes loaded with finished cloth are sequentially conveyed through the sorting conveyors on the side far from the longitudinal inbound conveyor line, the empty box return conveyor line, and the sorting conveyors on the side close to the longitudinal inbound conveyor line to the longitudinal inbound conveyor line. The longitudinal inbound conveyor line conveys the turnover boxes loaded with finished cloth to the horizontal inbound conveyor line. The horizontal inbound conveyor line conveys the turnover boxes loaded with finished cloth to the corresponding inbound transition conveyor line. The inter-warehouse conveyor line picks up the turnover boxes loaded with finished cloth on the inbound transition conveyor line and stores them on the finished product shelves. When it is necessary to outbound, the turnover boxes loaded with finished cloth on the finished product shelves are taken out by the inter-warehouse conveyor line and placed on the outbound transition conveyor line. The outbound transition conveyor line transfers the turnover boxes loaded with finished cloth to the horizontal outbound conveyor line. The horizontal outbound conveyor line conveys the turnover boxes loaded with finished cloth to the outbound transfer machine, conveys the turnover boxes loaded with finished cloth onto the outbound transfer machine. After the finished cloth in the turnover box on the outbound transfer machine is removed, the empty turnover box is conveyed by the horizontal outbound conveyor line to the empty box return conveyor line for recycling.

The branch line track 1021 is arranged parallel to one side of the grey fabric shelf 101 and extends along the length direction of the grey fabric shelf 101. The grey fabric stacker 1022 is slidably arranged on the branch line track 1021. Transition buffer lines 103 are arranged at both ends of the branch line track 1021. When there is one grey fabric stacker 1022, the grey fabric stacker 1022 is used to transfer the turnover box 2 containing grey fabric on the transition buffer line 103 at one end to the grey fabric shelf 101, and take out the turnover box 2 containing grey fabric on the grey fabric shelf 101 and transfer it to the transition buffer line 103 at the other end. When there are two grey fabric stackers 1022, one grey fabric stacker 1022 is used to transfer the turnover box 2 containing grey fabric on the transition buffer line 103 at one end to the grey fabric shelf 101, and the other grey fabric stacker 1022 is used to take out the turnover box 2 containing grey fabric on the grey fabric shelf 101 and transfer it to the transition buffer line 103 at the other end. The input main line 104 is arranged at one end of the grey fabric shelf 101 and is arranged at a right angle to the adjacent transition buffer line 103. The conveying direction of the input main line 104 is perpendicular to the conveying direction of the transition buffer line 103, and the input main line 104 is used to convey the turnover box 2 along the width direction of the grey fabric shelf 101. At least one side of the input end of the input main line 104 is provided with two grey fabric transfer machines 105. The grey fabric transfer machine 105 close to the input end of the input main line 104 is used to carry the turnover box 2 during loading, and the other is used to carry the empty turnover box 2. The input main line 104 is used to convey the turnover box 2 containing grey fabric on the grey fabric transfer machine 105 to the corresponding transition buffer line 103.

[0044] The fabric loosening and buffering device 4 is cooperated through the fabric feeding end conveying device 41, the intermediate conveying device 42 and the fabric discharging end conveying device 43 arranged in sequence along the conveying direction, and the fabric discharging end conveying device 43 is cooperated by arranging the fabric discharging frame 431, the fabric discharging conveying assembly 432, the flipping driving member 433, the fabric discharging fence 434 and the movable door 435. After the grey fabric loosened by the fabric loosening machine 3 is stacked on the fabric feeding end conveying device 41 to form a fabric stack, it is then conveyed to the intermediate conveying device 42 for temporary storage. When the fabric stack on the fabric discharging end conveying device 43 is about to be processed, one fabric stack temporarily stored on the intermediate conveying device 42 is conveyed to the fabric discharging end conveying device 43 to facilitate continuous processing of the fabric stack by the fabric shaping machine 5.

[0045] In this embodiment, the fabric feeding end conveying device 41, the conveying unit 421 and the fabric discharging conveying assembly 432 all adopt belt conveyors. The structures of the fabric feeding end conveying device 41 and the fabric discharging end conveying device 43 are roughly the same, but the fabric feeding end conveying device 41 does not need to realize the flipping function.

The two ends of the connecting conveying line 63 are respectively arranged at the fabric output ends of the two fabric pre-shaping machines 5, so that the grey fabric at the fabric output ends of the two shaping machines 5 can be stacked in the turnover boxes 2 at the two ends of the connecting conveying line 63 respectively. The empty turnover boxes 2 on the buffer conveying line 62 for empty turnover boxes are respectively conveyed to the two ends of the connecting conveying line 63 and stopped to stack the grey fabric at the fabric output ends of the fabric pre-shaping machines 5. When the turnover box 2 is filled with grey fabric, the grey fabric is cut, and the turnover box 2 filled with grey fabric is conveyed to the corresponding buffer conveying line 61 for fabric-carrying turnover boxes for storage, so that the circulating logistics device 8 can pick up the turnover boxes 2 filled with grey fabric at the output end of the buffer conveying line 61 for fabric-carrying turnover boxes.

[0048] As a preferred embodiment, both the two buffer conveying lines 61 for fabric-carrying turnover boxes and the buffer conveying line 62 for empty turnover boxes are formed by splicing a plurality of chain conveyors in the prior art into a long conveying line. The chain conveyor includes a chain conveying frame and two conveying chains rotatably arranged on both sides of the chain conveying frame. The turnover box 2 is carried on the two conveying chains for conveying. It can be understood that the two buffer conveying lines 61 for fabric-carrying turnover boxes and the buffer conveying line 62 for empty turnover boxes can also adopt belt conveyors, roller conveyors or other devices that can carry the turnover box 2 for conveying.

[0049] As a preferred embodiment, the connecting conveyor line 63 includes a linear conveyor 631 and a turning conveyor 632. One end of each of the two cloth-carrying turnover box buffer conveyor lines 61 and the empty turnover box buffer conveyor line 62 is connected to a turning conveyor 632. The turning conveyor 632 is used to first input the turnover box 2 onto the turning conveyor 632 along the length direction of the turnover box 2, and then output the turnover box 2 onto the cloth-carrying turnover box buffer conveyor line 61 along the width direction of the turnover box 2. The adjacent two turning conveyors 632 are connected by a linear conveyor 631. In this way, it is easy to move the empty turnover box 2 on the empty turnover box buffer conveyor line 62 to the corresponding turning conveyor 632 first, and then use this turning conveyor 632 to convey the empty turnover box 2 to the linear conveyor 631 at the designated end, and then use the linear conveyor 63 to convey the empty turnover box 2 to the turning conveyor 632 at the designated end for loading the greige cloth at the cloth output end of the fabric setting machine 5.

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

[0051] In order to facilitate the placement of the turnover box 2 at the fabric input end of the dyeing machine 7 and save the occupied space, a lifting and rotating mechanism 64 is provided on 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. The lifting and rotating mechanism 64 is arranged between the two conveyor chains of the chain conveyor to lift and rotate the turnover box 2 on the two conveyor chains by 90 degrees. The lifting and rotating mechanism 64 includes a 90-degree turning cylinder and a carrier table fixed to the piston rod end of the 90-degree turning cylinder. The 90-degree turning cylinder is driven to lift the carrier table to abut against the bottom of the turnover box 2, lift the turnover box 2 off the two conveyor chains, and then drive the carrier table to rotate 90 degrees by the 90-degree turning cylinder, thereby completing the turning of the turnover box 2.

[0052] Please refer to Figure 9 , the dyeing machine 7 is a machine that dyes the greige cloth by adding dyeing auxiliaries. In this embodiment, the dyeing machines 7 are arranged in two rows, and multiple dyeing machines 7 with different cylinder numbers are set in each row for combined use, and corridors are formed by connecting the dyeing machines 7 in each row. Stairs 71 are erected at both ends of each row of dyeing machines 7 to facilitate workers to enter and operate. The fabric input end of each dyeing machine 7 is close to the circulating logistics device 8 to facilitate the feeding of the greige cloth and the taking out of the dyed cloth (the dyed cloth is the cloth dyed by the dyeing machine 7).

[0053] Please refer to Figure 10, the solid arrows in the figure indicate the conveying direction of the turnover box 2 carrying the embryo cloth or dyed cloth, and the dashed arrows in the figure indicate the conveying direction of the empty turnover box 2. The circulating logistics device 8 includes a conveying loop 81, an outer handling line 82 and an inner handling line 83. The conveying loop 81 surrounds the outer periphery of two rows of dyeing machines 7, and the conveying loop 81 is used to intermittently convey the turnover box 2 in a cycle along the conveying loop 81. The outer handling line 82 is arranged outside the conveying loop 81 and is located between the conveying loop 81 and the output end of the to-be-dyed buffer device 6. The outer handling line 82 is used to transport the turnover box 2 carrying the embryo cloth on the cloth-carrying turnover box buffer conveying line 61 of the to-be-dyed buffer device 6 to the conveying loop 81, and transport the empty turnover box 2 on the conveying loop 81 to the empty turnover box buffer conveying line 62. The inner handling line 83 is arranged inside the conveying loop 81 and is located between the conveying loop 81 and the cloth-feeding end of each row of dyeing machines 7. The inner handling line 83 is used to transport the turnover box 2 carrying the embryo cloth on the conveying loop 81 to the cloth-feeding end of the designated dyeing machine 7, transport the empty turnover box 2 after the embryo cloth is introduced into the dyeing machine 7 and the turnover box 2 carrying the dyed cloth at the dyeing machine 7 to the conveying loop 81, and transport the empty turnover box 2 on the conveying loop 81 to the cloth-discharging end of the dyeing machine 7 (the cloth-discharging end and the cloth-feeding end are the same end). The empty turnover box 2 on the conveying loop 81 is transported to the empty turnover box buffer conveying line 62 through the outer handling line 82 for recycling. The turnover box 2 carrying the dyed cloth on the conveying loop 81 is finally transported to the water-pressing buffer device 9 to enter the next process.

[0054] The conveying loop 81 adopts a square conveying mechanism, and the outer handling line 82 and the inner handling line 83 are respectively arranged outside and inside one side of the square conveying mechanism in parallel. The extending length of the outer handling line 82 is smaller than the length of the corresponding side of the square conveying mechanism, which is convenient for arranging the water-pressing buffer device 9 outside the corresponding side of the square conveying mechanism. The extending length of the inner handling line 83 is equivalent to the length of the corresponding side of the square conveying mechanism, so as to facilitate the handling of the turnover box 2 with the dyeing machine 7. As a preferred embodiment, the square conveying mechanism is formed by splicing a plurality of chain conveyors, and lifting transfer machines are used for turning and conveying at the four corner positions of the square conveying mechanism and the connection with the water-pressing buffer device 9. Preferably, the square conveying mechanism adopts a rectangular conveying mechanism, and the outer handling line 82 and the inner handling line 83 are respectively arranged outside and inside the long side section of the rectangular conveying mechanism in parallel, so as to facilitate the overall layout.

[0055] As a preferred embodiment, the outer handling line 82 includes a handling ground rail 821 and a handling forklift 822 slidably disposed on the handling ground rail 821. The handling forklift 822 has forks that can extend and retract on both sides of the handling ground rail 821, and the forks are liftably disposed on the handling forklift 822. Through the sliding of the handling forklift 822 along the handling ground rail 821, in cooperation with the extension, retraction and lifting actions of the forks, the transfer of the turnover boxes 2 between the fabric-loaded turnover box buffer conveyor line 61 and the empty turnover box buffer conveyor line 62 and the conveying loop line 81 is realized. Similarly, the inner handling line 83 can also adopt the same embodiment as the outer handling line 82, which will not be elaborated here.

[0056] The usage method of the circular logistics device 8 includes the following steps: The outer handling line 82 takes out the turnover boxes 2 carrying greige fabrics one by one from the output end of the greige fabric turnover box buffer conveyor line 61, and transports the turnover boxes 2 carrying greige fabrics to the conveying loop 81 for intermittent conveyance during the intermittent period when the conveying loop 81 stops conveying. When the turnover box 2 carrying greige fabric is conveyed to the range where it can be handled by the inner handling line 83 (i.e., the long side section of the rectangular conveying mechanism), the inner handling line 83 takes out the turnover box 2 carrying greige fabric on the conveying loop 81 and transports it to the fabric inlet end of the designated dyeing machine 7, and transports the empty turnover box 2 formed after all the greige fabrics in the turnover box 2 at the fabric inlet end of the dyeing machine 7 are input into the dye vat of the dyeing machine 7 to the conveying loop 81. When multiple empty turnover boxes 2 on the conveying loop 81 pass through the handling range of the outer handling line 82, the outer handling line 82 transports a part of the turnover boxes 2 to the empty turnover box buffer conveyor line 62, and the remaining turnover boxes 2 continue to be intermittently conveyed along the conveying loop 81. When the dyed fabric formed after the dyeing machine 7 dyes the greige fabric needs to be taken out from the dye vat of the dyeing machine 7, the inner handling line 83 transports the empty turnover box 2 on the conveying loop 81 to the fabric outlet end of the dyeing machine 7 for storing the dyed fabric taken out from the dye vat of the dyeing machine 7. When the dyed fabric is stacked in the turnover box 2, the inner handling line 83 transports the turnover box 2 containing the dyed fabric to the conveying loop 81. When the conveying loop 81 carrying the turnover box 2 containing the dyed fabric passes through the water squeezing buffer device 9, it is conveyed to the water squeezing buffer device 9, and the empty turnover box 2 after the dyed fabric is taken out from the water squeezing buffer device 9 is conveyed to the conveying loop 81. When the conveying loop 81 carrying the empty turnover box 2 passes through the handling range of the inner handling line 83, the empty turnover box 2 on the conveying loop 81 is transported to the empty turnover box buffer conveyor line 62. In this way, a circular conveyance of greige fabric from the outer handling line 82 → conveying loop 81 → inner handling line 83 → fabric inlet end of the dyeing machine 7 is formed, a circular conveyance of dyed fabric from the fabric outlet end of the dyeing machine 7 → inner handling line 83 → conveying loop 81 → water squeezing buffer device 9 is formed, a circular conveyance of the empty turnover box 2 from the water squeezing buffer device 9 and the fabric inlet end of the dyeing machine 7 → conveying loop 81 → outer handling line 82 → empty turnover box buffer conveyor line 62 is formed, and a circular conveyance of the empty turnover box 2 from the water squeezing buffer device 9 and the fabric inlet end of the dyeing machine 7 → conveying loop 81 → inner handling line 83 → fabric outlet end of the dyeing machine 7 is formed. This is easy to realize the input of greige fabric and the output of dyed fabric for multiple dyeing machines 7, efficiently connect the logistics between the greige fabric shaping machine 5 and the water squeezing machine 10, greatly improve the logistics conveyance efficiency, and provide the best implementation plan for setting up a large-scale, efficient, and intelligent dyeing and finishing factory. In addition, the structure layout of the circular logistics device 8 is reasonable, which is convenient for the compact layout of each device in the dyeing and finishing workshop.

[0057] In this embodiment, three sets of water pressing buffer devices 9 are arranged in parallel to connect three sets of water pressing machines 10 for the water pressing process. The water pressing buffer device 9 can adopt a structure with the same principle as the to-be-dyed buffer device 6. The water pressing buffer device 9 includes two cloth dyeing buffer lines 91, an empty box buffer line 92, and an end conveying line 93. The two cloth dyeing 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 cloth dyeing buffer lines 91 and the empty box buffer line 92 to form an E-shaped conveying line. The input end of the water pressing buffer device 9 is connected to the conveying loop 81 of the circulating logistics device 8, so that the turnover boxes 2 carrying dyed cloth on the conveying loop 81 can be classified and conveyed to the two cloth dyeing buffer lines 91 according to the color of the dyed cloth, and the turnover boxes 2 that are emptied after taking the dyed cloth from the cloth dyeing buffer line 91 are conveyed along the empty box buffer line 92 to the conveying loop 81, and then transferred to the empty turnover box buffer conveying line 62 through the outer handling line 82 outside the conveying loop 81. In this way, it can ensure the smooth operation of a series of logistics such as the input of the greige cloth of the dyeing machine 7, the output of the dyed cloth after the dyeing machine 7 finishes processing, and the recycling of the empty turnover boxes 2, effectively improving the logistics conveying efficiency of the fabric input and output 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 being beneficial to the intelligent and standardized production of the dyeing and finishing industry.

[0058] As a preferred embodiment, both the water pressing buffer device 9 and the to-be-dyed buffer device 6 are connected to the outside of the same side of the square conveying mechanism. In this way, it is beneficial to the spatial layout of each device in the entire production workshop. The overall layout structure is in a U shape, shortening the production line length, so that the greige cloth storage device 1 and the finished product storage device 14 are located on the same side of the production workshop, facilitating logistics conveying.

[0059] Please refer to Figure 1 , in this embodiment, three water pressing machines 10 are arranged in parallel. The water pressing machine 10 is a machine used to remove excess water from the dyed cloth, which belongs to the prior art and will not be elaborated here.

[0060] In this embodiment, three finished product setting machines 11 are arranged in parallel. The finished product setting machine 11 is a machine that changes the hand feeling, slipperiness, width, gram weight, etc. of the dyed cloth by impregnating various dyeing chemicals for softening, stiffening, anti-slip, stretching, and resin finishing, etc., which belongs to the prior art and will not be elaborated here.

[0061] The cloth inspection and winding device 12 uses an existing cloth inspection machine and a winding machine in combination, which belongs to the prior art and will not be elaborated here.

[0062] Please refer to Figure 11 and Figure 12, the sorting device 13 includes a cloth roll conveying device 131, an identification device 132, a rejection device 133, an automatic packing machine 134, a transfer device 135, a buffer conveying device 136, a sorting conveying unit 137, and a roll unloading device 138. The cloth roll conveying device 131 is connected to the cloth output end of the cloth inspection and winding device 12 to convey the cloth roll with an identification code. The cloth roll conveying device 131 is provided with an identification device 132 and a rejection device 133. The identification device 132 is used to read the identification code information, and the identification code information includes information such as order number, customer name, and cloth roll specification. The identification code information is distributed to the corresponding sorting conveying unit 137 by programming control to control the classified conveyance of various types of cloth rolls to their respective corresponding sorting conveying units 137 according to the identification code information. The cloth roll that cannot read the identification code information is rejected from the cloth roll conveying device 131 by the rejection device 133. The automatic packing machine 134 is arranged at the output end of the cloth roll conveying device 131 to convey the identified cloth roll to the automatic packing machine 134 for packing. The transfer device 135 is arranged at the output end of the automatic packing machine 134 to transfer the packed cloth roll onto the buffer conveying device 136. The output end of the buffer conveying device 136 is provided with a plurality of sorting conveying units 137. The whole conveying line formed by the plurality of sorting conveying units 137 and the buffer conveying device 136 is parallel to the cloth roll conveying device 131, and the automatic packing machine 134 is located between the buffer conveying device 136 and the output end of the cloth roll conveying device 131. Each roll unloading device 138 is correspondingly arranged on one side of each sorting conveying unit 137, and the plurality of roll unloading devices 138 are arranged continuously or at intervals. In this embodiment, a roll unloading device 138 is arranged every other sorting conveying unit 137. When the cloth roll is conveyed to the corresponding sorting conveying unit 137, the sorting conveying unit 137 stops conveying and transfers the cloth roll to the corresponding roll unloading device 138 to unload the cloth roll onto the turnover box 2 below the roll unloading device 138. Specifically, the cloth roll conveying device 131, the buffer conveying device 136, and the sorting conveying unit 137 can all adopt belt conveyors. The sorting conveying unit 137 can adopt a flipping method to roll the cloth roll onto the roll unloading device 138. The roll unloading device 138 has two openable and closable roll unloading plates, and the two roll unloading plates are arranged in a V shape. When the two roll unloading plates are closed, a container for carrying the cloth roll is formed. When the two roll unloading plates are opened, the cloth roll falls from between the two roll unloading plates onto the turnover box 2 below.

[0063] Please refer to Figure 13 and Figure 14 , Figure 13The solid arrows in the figure indicate the conveying direction of the turnover box 2 carrying the finished cloth, and the dashed arrows in the figure indicate the conveying direction of the empty turnover box 2. The finished product storage device 14 includes a finished product shelf 141, an inter-store conveyor line 142, an inbound transition conveyor line 143, an outbound transition conveyor line 144, a lateral inbound conveyor line 145, a longitudinal inbound conveyor line 146, an empty box return conveyor line 147, a sorting conveyor 148, a lateral outbound conveyor line 149, and an outbound transfer machine 140. The finished product shelf 141 includes multiple layers of storage spaces for storing the turnover box 2 containing the finished cloth. The finished product shelf 141 is provided with at least one row, and a set of inter-store conveyor lines 142 is arranged between every two rows of the finished product shelf 141. The inter-store conveyor line 142 extends along the length direction of the finished product shelf 141 to store the turnover box 2 carrying the finished cloth on the finished product shelf 141 by the inter-store conveyor line 142 and take out the turnover box 2 carrying the finished cloth during outbound and place it on the outbound transition conveyor line 144 at the output end of the inter-store conveyor line 142. The inbound transition conveyor line 143 and the outbound transition conveyor line 144 are respectively arranged in parallel at both ends of the inter-store conveyor line 142. The lateral 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 lateral inbound conveyor line 145, so that the turnover box 2 containing the finished cloth on the lateral inbound conveyor line 145 can be conveyed onto the inbound transition conveyor line 143, so that the inter-store conveyor line 142 can take away the turnover box 2 containing the finished cloth on the inbound transition conveyor line 143. The longitudinal inbound conveyor line 146 extends along the length direction of the finished product shelf 141 from the input end of the lateral inbound conveyor line 145 for conveying the turnover box 2 carrying the finished cloth along the length direction of the finished product shelf 141. The longitudinal inbound conveyor line 146 is perpendicular to the lateral inbound conveyor line 145 to facilitate the turning conveyance of the turnover box 2 carrying the finished cloth and is beneficial to the space layout. The empty box return conveyor line 147 is arranged in parallel on one side of the longitudinal inbound conveyor line 146 away from the finished product shelf 141. A plurality of 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 on the side away from the longitudinal inbound 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 on the side close to the longitudinal inbound conveyor line 146, and the longitudinal inbound conveyor line 146. Preferably, in this embodiment, the three sorting conveyors 148 on the side close to the longitudinal inbound conveyor line 146 are arranged at intervals. The three sorting conveyors 148 arranged at intervals are preferably chain conveyors of the prior art to carry the turnover box 2 to realize linear conveyance, but are not limited to chain conveyors. The six sorting conveyors 148 on the side away from the longitudinal inbound conveyor line 146 are arranged continuously. The six sorting conveyors 148 arranged continuously are preferably lifting transfer machines of the prior art to carry the turnover box 2 to realize corner conveyance, but are not limited to lifting transfer machines.Every two of the six sorting conveyors 148 form a group. In each group, one sorting conveyor 148 is used to place the turnover box 2 for carrying the finished cloth unloaded from the unwinding device 138, and the other sorting conveyor 148 is used to place the spare turnover box 2, so that after the turnover box 2 on the sorting conveyor 148 in this group is full of finished cloth and is conveyed out, the spare turnover box 2 is conveyed in for loading the next box of finished cloth. The empty box return conveyor line 147 is used to convey 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 arranged directly below each unwinding device 138 for classifying and storing the finished cloth on the corresponding sorting conveyor 148. One side of the transverse outbound conveyor line 149 is arranged close to 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 onto the transverse outbound conveyor line 149. The transverse outbound conveyor line 149 extends along the width direction of the finished product shelf 141. At each end of the transverse outbound conveyor line 149, there are two outbound transfer machines 140 on each side for placing the turnover box 2 carrying the finished cloth, so as to facilitate the handling of the finished cloth in the turnover box 2 onto the finished cloth truck 1402 on one side of the loading platform 1401. The other end of the transverse outbound conveyor line 149 extends to the input end of the empty box return conveyor line 147, so that the empty turnover box 2 after the finished cloth is taken away by the outbound transfer machine 140 can be returned to the empty box return conveyor line 147 through the transverse outbound conveyor line 149 for recycling.

[0064] Working principle of the finished product storage device 14: The empty turnover boxes 2 are stored on a section of the empty box return conveyor line 147 close to the horizontal outbound conveyor line 149. The empty turnover boxes 2 are conveyed by the empty box return conveyor line 147 to each sorting conveyor 148 on the side far from the longitudinal inbound conveyor line 146. The unwinding device 138 of the sorting device 13 classifies and stores the finished cloth into the turnover boxes 2 on the corresponding sorting conveyor 148. When the amount of finished cloth stored in the turnover box 2 reaches the specified quantity (for example, ten rolls of finished cloth are placed in each box), the turnover box 2 loaded with finished cloth is successively conveyed to the longitudinal inbound conveyor line 146 through the sorting conveyor 148 on the side far 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. The longitudinal inbound conveyor line 146 conveys the turnover box 2 loaded with finished cloth to the horizontal inbound conveyor line 145. The horizontal inbound conveyor line 145 conveys the turnover box 2 loaded with finished cloth to the corresponding inbound transition conveyor line 143. The inter-warehouse conveyor line 142 takes away the turnover box 2 loaded with 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 loaded with 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 outbound transition conveyor line 144 transfers the turnover box 2 loaded with finished cloth to the horizontal outbound conveyor line 149. The horizontal outbound conveyor line 149 conveys the turnover box 2 loaded with finished cloth to the outbound transfer machine 140 and conveys the turnover box 2 loaded with 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 conveyed by the horizontal outbound conveyor line 149 to the empty box return conveyor line 147 for recycling. In this way, the empty turnover box 2 is first conveyed to the sorting conveyor 148 under the unwinding device 138 of the sorting device 13, and the turnover box 2 filled with finished cloth is successively conveyed to the empty box return conveyor line 147 → the sorting conveyor 148 on the side close to the longitudinal inbound conveyor line 146 → the longitudinal inbound conveyor line 146 → the horizontal inbound conveyor line 145 → the inbound transition conveyor line 143 → the inter-warehouse conveyor line 142 → the outbound transition conveyor line 144 → the horizontal outbound conveyor line 149 → the outbound transfer machine 140. After the finished cloth is removed from the outbound transfer machine 140, the empty turnover box 2 is conveyed by the horizontal outbound conveyor line 149 to the empty box return conveyor line 147 for recycling. This effectively ensures the smooth progress of the incoming and outgoing of the finished product shelf 141 and improves the conveying efficiency of the incoming and outgoing of the finished cloth. In addition, the finished product storage device 14 is easy to implement, has a low cost, a reasonable structural design, and a high space utilization rate.

The inter-library stacker 1422 is provided with a fork that can extend and retract to both sides and can be lifted and lowered, so that the turnover box 2 can be carried on the fork for handling. In this embodiment, two inter-library stackers 1422 are provided, one for inbound handling and the other for outbound handling. It can be understood that one inter-library stacker 1422 can also be provided for both inbound and outbound handling. Through one or two inter-library stackers 1422, the loading and unloading of the finished product shelves 141 can be realized.

[0069] As a preferred embodiment, the empty box return conveyor line 147 includes a chain conveyor section 1471 and a lifting transfer section 1472. The chain conveyor section 1471 is mainly composed of a plurality of chain conveyors spliced together, and the lifting transfer section 1472 is mainly composed of a plurality of lifting transfer machines spliced together. The lifting transfer machine can adopt a combination of a lifting roller conveyor mechanism and a chain conveyor mechanism to respectively achieve conveying in two mutually perpendicular directions. On both sides of each lifting transfer machine, it respectively forms a cross-conveying line with two corresponding sorting conveyors 148 for inputting the empty turnover boxes 2 and outputting the turnover boxes 2 filled with finished cloth.

[0070] As a preferred embodiment, the sorting conveyor 148 can adopt a chain conveyor. The chain conveyor includes two parallel chains that can rotate and convey, and conveys the turnover box 2 by carrying it on the two chains.

[0071] As a preferred embodiment, the horizontal outbound conveyor line 149 includes a slide rail 1491 fixed to the ground and extending along the width direction of the finished product shelf 141, and a horizontal outbound vehicle 1492 that can reciprocally slide on the slide rail 1491. The horizontal outbound vehicle 1492 is provided with a chain transmission mechanism for driving the turnover box 2 on the outbound transition conveyor line 144 to be input onto the horizontal outbound vehicle 1492 and driving the turnover box 2 on the horizontal outbound vehicle 1492 to be output onto the outbound transfer machine 140.

[0072] As a preferred embodiment, the outbound transfer machine 140 adopts a lifting roller type chain conveyor. The lifting roller type chain conveyor includes a liftable roller conveyor device and two conveyor chains oppositely arranged on both sides of the roller conveyor device. The conveying direction of the roller conveyor device is perpendicular to the conveying direction of the conveyor chains. The turnover box 2 is carried on the two conveyor chains and conveyed onto the outbound transfer machine 140, and then the turnover box 2 is lifted by the roller conveyor device and transferred to the adjacent transfer machine 140.

[0073] In summary, for the dyeing and finishing production system of the present invention, the turnover box 2 carrying the grey fabric is conveyed by the grey fabric storage device 1 to the fabric loosening machine 3 for fabric loosening. The loosened grey fabric is cached on the fabric loosening buffer device 4 by the turnover box 2. The turnover box 2 on the fabric loosening buffer device 4 is conveyed box by box to the grey fabric setting machine 5 for grey fabric setting. The grey fabric after setting is cached on the to-be-dyed buffer device 6 by the turnover box 2. The circulating logistics device 8 receives the turnover box 2 containing the grey fabric on the to-be-dyed buffer device 6, transfers the turnover box 2 containing the grey fabric to the fabric inlet end of the dyeing machine 7, conveys the emptied turnover box 2 after introducing the grey fabric into the dyeing machine 7 onto the circulating logistics device 8 for separately conveying to the to-be-dyed buffer device 6 and the fabric outlet end of the dyeing machine 7. The dyed fabric after dyeing in the dyeing machine 7 is stored in the turnover box 2 at the fabric outlet end of the dyeing machine 7 and transferred onto the circulating logistics device 8. The turnover box 2 carrying the dyed fabric is finally conveyed to the water squeezing buffer device 9. The turnover box 2 carrying the dyed fabric on the water squeezing buffer device 9 is conveyed box by box to the water squeezing machine 10 for water squeezing. The water-squeezed dyed fabric successively passes through the finished product setting machine 11, the fabric inspection and winding device 12, the sorting device 13 and the finished product storage device 14 to successively perform setting, fabric inspection and winding, sorting and storage and retrieval on the water-squeezed dyed fabric. In this way, a full-integrated production chain from grey fabric warehousing, grey fabric dyeing and finishing to finished product outbound can be realized, ensuring that all links in the whole production process are carried out orderly, smoothly and continuously, greatly improving the production efficiency, reducing the idle time of equipment, reducing energy consumption, reducing the number of workers and reducing the labor intensity.
