Description

Technical Field

[0001] This invention belongs to the technical field of hanging systems, specifically relating to a hanging frame conveying system. Background Technology

[0002] In factories that process clothing, curtains, mattresses, and other products, materials are often transported to various processing stations manually for processing. After processing, the materials are then sorted and transported to the next station or storage area manually. Manual processing and handling are inefficient. To improve processing efficiency, it is necessary to add dedicated transportation personnel and equipment, which will increase costs.

[0003] With the popularization of mechanical automation, some processing plants have begun to introduce hanging systems. In order to facilitate the transportation of goods and make reasonable use of space, the hanging system is usually set at the top. The hanging system transports the racks with suspended goods to the workstations located on the branch rails through a main rail. After the workstation completes its process, the racks are transported to the next workstation or to the outbound position through the main rail.

[0004] In each workstation, processing personnel perform one step of the processing on sheets or semi-finished products. In existing technologies, due to differences in experience and efficiency among personnel, and the lack of coordinated control and intelligent scheduling across multiple workstations, some workstations experience an accumulation of unfinished products, becoming efficiency bottlenecks, while other workstations have significant idle time waiting for the next rack to arrive, thus impacting overall production efficiency. Furthermore, when errors occur in one or more processing steps, existing systems cannot automatically handle them, requiring manual selection and subsequent unified inspection and rework, which consumes substantial manpower and time costs. Summary of the Invention

[0005] This invention addresses the aforementioned problems and aims to provide a hanging rack conveying system capable of efficiently and balancedly transporting racks to various workstations within a suspension system, and capable of correcting errors in a particular process. The invention employs the following technical solution:

[0006] This invention provides a rack conveying system, characterized by comprising: a hanging device for conveying racks carrying goods to be processed, having multiple workstations for processing the goods; a control host for controlling the conveying process of the racks; and a management terminal communicatively connected to the control host, for conveying the racks sequentially to corresponding workstations according to predetermined multiple processes via the control host, wherein each process corresponds to multiple workstations, and the management terminal includes at least: a management information storage unit, storing at least the rack identification code of the rack, the process number of the corresponding process, and the workstation number of the corresponding workstation; a workstation real-time statistics unit, for counting the real-time number of racks in each workstation; and a workstation allocation unit, for allocating the racks to corresponding workstations according to the process number of the next process, the real-time number of racks, and predetermined allocation rules, and the control host including at least: a rack entry control unit, controlling the hanging device to convey the racks to the corresponding workstations according to the allocated workstation numbers.

The rack entry control unit further includes: a diversion judgment unit for determining whether to enter the current workstation based on the assigned workstation number and the rack identification code read by the rack reader; and a diversion control unit for controlling the corresponding workstation entry mechanism to release the rack when the diversion judgment unit determines that the rack has entered the corresponding workstation.

[0009] The rack conveying system provided by this invention may also have the following technical features: when the rack identification code is read by the rack reader and the corresponding workstation entry mechanism releases the rack, the real-time statistics unit of the workstation increments the real-time rack count by 1; when the processing personnel confirm the completion of processing through the operation terminal, the real-time rack count is decremented by 1, thereby obtaining the real-time rack count. The allocation rule is as follows: the rack is allocated to the workstation with the fewest real-time racks corresponding to the next process; when the real-time rack counts of multiple workstations are the same, the multiple racks are sequentially allocated to the multiple workstations.

[0013] The rack conveying system provided by this invention may also have the following technical features: the blocking mechanism includes a first blocking member and a second blocking member, both rotatably mounted on one end of the connecting rail via a bracket. A notch is formed between the opposing ends of the first and second blocking members. When the rack reaches this position, it is guided into the notch by the first blocking member and thus blocked. The exit drive mechanism includes: a gear set meshing with the conveyor chain of the main rail; a drive shaft connected to the gear set; an exit chain mounted on the drive shaft; and a rack pushing member fixed on the exit chain for pushing the rack to move along the connecting rail. The second blocking member has a pushing protrusion, and the rack pushing member has a protruding blocking member pushing block.

[0014] The rack conveying system provided by this invention may also have the following technical features: the gear set includes a clutch gear; the departure drive mechanism further includes: a drive rod, which is connected to the clutch gear for driving the clutch gear closer to the main track and engaging with the conveyor chain of the main track, and for driving the clutch gear away from the main track, thereby disengaging from the conveyor chain; and a switching drive cylinder for driving the drive rod to rotate; the number of rack pushing components and rack stopping components is two pairs; the sensing mechanism further includes: a drive rod sensor, disposed at the drive rod, for sensing the position of the drive rod to obtain the working state of the rack departure unit; and a pushing component sensor, disposed at a predetermined position beside the departure track via a bracket, for sensing arrival... When a pair of the hanger pushing members and hanger stopping members reach this position, and another pair of the hanger pushing members and hanger stopping members are located on the main track, the departure start control unit determines to start departure when the hanger identification code is read by the departure hanger reader, the push rod sensor senses the vacant push rod member, and the working state of the hanger departure device is stopped.

[0016] Invention Function and Effect

[0017] The rack conveying system according to the present invention includes a hanging device with multiple workstations, a control host, and a management terminal. The management terminal is communicatively connected to the control host and has a management information storage unit, a workstation real-time statistics unit, and a workstation allocation unit. Therefore, it can count the real-time number of racks in each workstation based on the real-time status information of each workstation obtained from the control host, and allocate the next process workstation to the rack based on the real-time number of racks and send it to the control host. The control host controls the hanging device to convey the rack to the corresponding workstation for processing according to the allocated workstation. Therefore, the rack conveying system of the present invention can balance the workload according to the real-time status of each workstation, avoiding some workstations from becoming bottlenecks in the system or being idle for a long time, and greatly improving the overall processing efficiency of the system.

[0054] To make the technical means, creative features, objectives and effects of the present invention easy to understand, the following describes the hanging rack conveying system of the present invention in detail with reference to the embodiments and accompanying drawings.

[0055] <Example>

[0056] like Figure 1 As shown, this embodiment provides a rack conveying system for sequentially conveying racks from a hanging device to various workstations for processing according to a predetermined process sequence. The rack conveying system 10 includes a hanging device 100, a management terminal 200, a control host 300, and multiple operating terminals 400. The hanging device 100 is installed on the ceiling of the processing plant and conveys sheet materials or semi-finished garments to be processed in a hanging manner. The control host 300 controls the conveying process of the hanging device 100. The management terminal 200 is communicatively connected to the control host 300 and is used to store various information such as order information and process flow information. Based on this information, the management terminal 200 controls the conveying process of the hanging device 100 through the control host 300. The operating terminals 400 are respectively installed at each workstation of the hanging device 100 for operation by the processing personnel at the corresponding workstation.

[0057] like Figure 2As shown, in this embodiment, the hanging device 100 includes multiple annular main tracks 110, and adjacent main tracks 110 are connected by connecting tracks. Each main track 110 is connected to several U-shaped branch tracks 120, and each branch track 120 is provided with several workstations 121 for processing sheet materials or semi-finished garments on the hanger. Each workstation 121 corresponds to a specific process.

[0058] The distribution of multiple workstations 121 is pre-determined based on factory conditions and actual processing volume. For factories with large areas and high processing volumes, multiple workstations 121 on each branch rail 120 are used for relatively simple processes; for factories with small areas and low processing volumes, multiple workstations 121 on each branch rail 120 are used for all processes of a product, or for the main processes of a product. In this embodiment, a large factory with high volume is used as an example. There are three main rails 110. The first two main rails 110 are each connected to four branch rails 120, and the last main rail 110 is connected to three branch rails 120. The four workstations 121 on each branch rail 120 are used to perform the same process. For example... Figure 2 As shown, the workstations 121 on the first ten branch rails 120 are used to perform the ten processes X1-X10 respectively, and the last branch rail 120 is equipped with four inspection stations 122 for quality inspection of the garments that have completed all ten processes.

[0059] like Figure 3 As shown, a hanger that has completed the current process on a support rail 120 is transported via the main rail 110 to the support rail 120 corresponding to the next process.

[0060] like Figure 4 As shown, the main track 110 includes a support track 111 and a drive track 112. The support track 111 supports the hanger, and the drive track 112 has a conveyor chain 1121 and several push rod components 1122 disposed on the conveyor chain 1121. Driven by the conveyor chain 1121, the push rod components 1122 can push the hanger located on the support track 111 to move along the support track 111, thereby realizing the transportation of the hanger. In this embodiment, identification codes are provided on both the push rod components 1122 and the hanger.

[0061] The support track 111 includes several support track sections and a mounting frame 113. The lower part of the mounting frame 113 has a lower mounting groove 1131, within which several track module components 114 are detachably installed end-to-end to form support track sections. The upper part of the mounting frame 113, corresponding to the lower mounting groove 1131, has an upper mounting groove 1132. A conveyor chain 1121 is installed within the upper mounting groove 1132, and push rod components 1122 are fixed to the conveyor chain 1121 at intervals. The centerline of the upper mounting groove is collinear with the centerline of the lower mounting groove, allowing the support track and drive track to be aligned, facilitating better pushing and transport of the hanger.

[0062] In this embodiment, the structure of the support rail 120 is the same as that of the main rail 110, that is, it has a conveyor chain 1121 and a push rod component 1122, which can push the hanger to move through the push rod component 1122.

[0063] like Figure 5 As shown, the entry mechanism 151 is installed on one side of the main rail 10. In order to allow the hanger on the bearing rail 111 of the main rail 110 to smoothly enter the workstation along the entry mechanism 151, an entry guide module component 115 is required at the connection between the entry mechanism 151 and the main rail 110 to allow the hanger to change its direction of movement. Figure 7 As shown, the station entry guide module component 115 is installed between the track module components 114.

[0064] like Figure 6-7 As shown, the station entry guide module component 115 includes a station entry guide seat 1151, a guide plate 1152, and a drive assembly. The station entry guide seat 1151 is mounted on the lower mounting groove 1131 of the mounting frame 113, and has a mounting section 11511 and a stabilizing section 11512. The surface of the mounting section 11511 is recessed downwards to form a mounting groove 11513. The guide plate 1152 is rotatably mounted in this mounting groove 11513 via a rotating shaft 11521. Driven by the drive assembly, the guide plate 1152 can rotate around the rotating shaft 11521. The guide plate 1152 has two states: a retracted state and a rotated-out state. In the retracted state, the hanger can move along the mounting section 11511 into the stabilizing section 11512 and continue running on the main track 110. In the rotated-out state, the guide plate 1152 is connected to the station entry mechanism 151, and the hanger can move along the mounting section 11511 into the station entry mechanism 151.

[0065] Two stabilizing bars 11514 protrude upwards from the surface of the stabilizing section 11512. These two stabilizing bars 11514 are positioned along the direction of movement of the hanger, providing cushioning as the hanger passes through the mounting section 11511 and enters the stabilizing section 11512 with the guide plate 1152 in the retracted state, allowing for smoother movement of the hanger. Due to the special structural design of the mounting section 11511, such as the mounting groove 11513 and the guide plate 1152, there is some resistance when the hanger runs on the mounting section 11511, causing it to sway during movement. To prevent excessive swaying and ensure stable continued movement, the stabilizing bar 11514 structure is provided on the surface of the stabilizing section 11512.

[0066] like Figure 7 As shown, the rotation of the guide plate 1152 is controlled by a drive assembly. The bottom surfaces of the mounting section 11511 and the stabilizing section 11512 are recessed to form a receiving cavity 1153, and the drive assembly is installed in the receiving cavity 1153. The drive assembly includes a cylinder 1161 and a drive plate 1162. The outer end of the piston rod 11611 of the cylinder 1161 is fixed to the drive plate 1162. The drive plate 1162 and the guide plate 1152 are linked together. When the piston rod 11611 drives the drive plate 1162 to move back and forth, it can drive the guide plate 1152 to rotate.

[0067] like Figure 4-5 As shown in Figure 8, an identification module component 118 is located upstream of the entrance guidance module component 115. The identification module component 118 includes a module body 1181 and an identifier 1182, as shown in Figure 8. Figure 8As shown, the main body of the module 1181 is a long, rectangular block structure with a hollow interior forming a cavity 1183. The identifier 1182 is fixedly installed inside the cavity 1183, and circuit boards 1184 are provided on both sides of the identifier 1182. An identification code is provided on the bracket. When the bracket passes over the main body of the module 1181, the identifier 1182 can read the identification code and transmit it to the system to determine whether the bracket needs to enter the workstation. Each workstation's entry mechanism has at least one identification module component 118 upstream, used to identify whether the passing rack needs to enter the workstation. If the system determines that the rack needs to enter the workstation, the control cylinder 1161 is activated, driving the guide plate 1152 to rotate, so that the guide plate 1152 connects with the entry mechanism, guiding the rack into the entry mechanism. If the system determines that the rack does not need to enter the workstation, the guide plate 1152 is retracted, and the rack can enter the stabilization section 11512 along the installation section 11511 and continue to be transported on the main track 110. The outer side of the module body 1181 is provided with protrusions 11811 that cooperate with the limiting protrusions 11311 on both sides of the lower installation groove 1131, facilitating the insertion and installation of the module body 1181 into the lower installation groove 1131.

[0068] In this embodiment, the push rod component 1122 is provided with a push rod identification code. When passing the identification module component 118, the bracket and the corresponding push rod component 1122 need to be identified and read by the identification module component 118 simultaneously. To prevent the bracket from automatically rolling forward due to inertia and detaching from the push rod component 1122, such as... Figure 7 As shown, buffer plates 1141 are provided along the length direction on both the inner and outer sides of the identification module component 118 and / or the track module component 114 located upstream of the identification module component 118. During the rolling process of the hanger's rollers, friction is generated between them and the buffer plates 1141, thus buffering the hanger and ensuring that the hanger is pushed by the push rod component 1122 when it enters the identification module component 118. This allows the push rod component 1122 and the hanger to be simultaneously identified by the identification module component 118. The buffer plates 1141 can be made of materials that provide a certain resistance to the hanger, such as brushes or non-woven fabric, and can be directly fixed to the sides of the track module component 114 and the identification module component 118.

[0069] like Figure 9As shown, this embodiment provides a double-wheel hanger 40, which runs on the support track 111 via rollers 41 set at the top. The double-wheel hanger 40 is a hanger with two rollers 41 (in actual use, a single-wheel hanger can also be selected as needed, which is a hanger with one roller, not shown in the figure). In order to ensure the stability of the double-wheel hanger 40 during operation, a stabilizing frame 42 is provided at the bottom of the double-wheel hanger 40. The two ends of the stabilizing frame 42 are connected to the two rollers 41 respectively, and a hanging rod 43 is provided in the middle of the stabilizing frame 42. The hanging rod 43 is used to hook clothes hangers, carrying frames, carrying bags, etc. used to carry clothes and other goods. As shown in the figure, the roller 41 is composed of two front and rear discs 411 and a connecting rod 412 connecting the two front and rear discs 411. An identification code is installed in the disc 411.

[0070] like Figure 9-10 As shown, when the dual-wheel hanger 40 runs on the main track 110, the two discs 411 are located on the inner and outer sides of the track module component 114 respectively. The bottom of the two discs 411 runs along the support track 111. There is a concave part between the two discs 411, forming a space for the track module component 114 to pass through. That is, the height of the top surface of the track module component 114 is higher than the height of the lowest point of the two discs 411, so that the dual-wheel hanger 40 is not easy to fall off when running on the support track 111. In addition, the track module component 114 can guide the discs of the dual-wheel hanger 40, so that the dual-wheel hanger 40 can move along the extension direction of the track module component 114.

[0071] The push rod component 1122 used in this embodiment has a special structure and installation method, such as Figure 11-13 As shown, the push rod component 1122 includes a main body 11221. One side of the main body 11221 has an arc-shaped concave surface 11222 that mates with the disc of the double-wheel bracket 40. This arc-shaped concave surface 11222 allows the disc of the double-wheel bracket 40 to be embedded, enabling the push rod component 1122 to push the double-wheel bracket 40 to move. The top of the arc-shaped concave surface 11222 of the main body 11221 has a mounting groove 11223 that mates with the conveyor chain 1121. The mounting groove 11223 has several fixing protrusions 11224 that can be embedded in the conveyor chain 1121 and fix the main body 11221 to the conveyor chain 1121. A push rod chip 11225 is also installed at the bottom of the main body 11221. The push rod chip 11225 contains a push rod identification code, enabling the push rod component to be identified by the identification module component. See also... Figure 11The two adjacent push rod components 1122 are installed in opposite directions. This installation method is to prevent the rollers of the hanger from slipping off due to gravity and separating the hanger from the push rod component when the track is transported in an inclined direction, which would lead to subsequent identification errors. By installing the two adjacent push rod components 1122 in opposite directions, the push rod component 1122 on the rear side can form a certain obstruction for the hanger, thereby confining the hanger between the two push rod components 1122 and avoiding errors.

[0072] like Figure 14-15 As shown, the rack exit unit 152 includes a first mounting bracket 521, a second mounting bracket 522, a connecting rail 523, a blocking mechanism 524, an exit drive mechanism 525, and an exit mechanism 526.

[0073] The connecting rail 523 is installed between the branch rail 120 and the main rail 10 via the first mounting bracket 521 and the second mounting bracket 522. One end of the connecting rail 523 is close to the branch rail 120, and a stop mechanism 524 is provided at this end; the other end is connected to the main rail 110 via the exit mechanism 526. The connecting rail 523 is inclined, with the end closer to the branch rail 120 being relatively higher. Preferably, the inclination angle of the connecting rail 523 is 3°, so that the hanger can slide down slowly along the connecting rail 523 by gravity, and avoids safety hazards caused by rapid sliding.

[0074] The blocking mechanism 524 is used to block or allow the rack to pass through one end of the connecting rail 523. The blocking mechanism 524 includes a first blocking member 5241 and a second blocking member 5242 arranged opposite to each other.

[0075] like Figure 16-17 As shown, a first pivot hole 52411 is provided in the middle of the first blocking member 5241, and a first clearance hole 52412 is provided near the first pivot hole 52411. The end face of the first blocking member 5241 away from the first clearance hole 52412 is the first blocking end 52413. The first blocking end 52413 has an outwardly protruding arc-shaped surface, which facilitates the introduction and exit of the hanger. A first spring receiving cavity 52414 is provided on one side of the first blocking member 5241, and a first spring 52415 is disposed in the first spring receiving cavity 52414, with one end of the first spring 52415 extending into the first clearance hole 52412. The pivot passes through the first pivot hole 52411 to rotatably mount the first blocking member 5241 on the first mounting bracket 521. The first mounting bracket 521 also has a first limiting post (not shown in the figure) extending vertically. The end of the first limiting post extends into the first clearance hole 52412, so that the end of the first blocking member 5241 is limited by the first limiting post 52416. Therefore, the first blocking member 5241 can rotate around the pivot under the action of external force, and the range of rotation is limited by the arc of the first clearance hole 52412.

[0076] like Figure 18-19 As shown, the second blocking member 5242 has a second pivot hole 52421, a second clearance hole 52422, a second blocking end 52423, a second spring receiving cavity 52424, a second spring 52425, and a second limiting post 52426. These structures and working principles are basically the same as those of the first blocking member 5241, and therefore will not be described in detail. On one side of the second blocking member 5242 ( Figure 19 The upper part of the device also has a push protrusion 52427, which the exit drive mechanism 525 can abut and push the push protrusion 52427, thereby driving the second blocking member 5242 to rotate along the shaft and release the rack.

[0077] Therefore, both the first blocking member 5241 and the second blocking member 5242 can be rotatably mounted on the first mounting bracket 521 and are arranged in an inward V-shape. An V-shaped notch is formed between their opposing ends (i.e., between the first blocking end 52413 and the second blocking end 52424). The hanger enters the connecting rail 523 from the support rail 120. The rollers of the hanger ride on the connecting rail 523 and are guided by the first blocking member 5241 into the V-shaped notch and are stuck in the notch, thereby blocking the hanger to be dispatched.

[0078] like Figure 14-15 As shown, the departure drive mechanism 525 is used to drive the release mechanism 524 to release the hanger and drive the hanger to move along the connecting rail 523 onto the main rail 110. The departure drive mechanism 525 includes a switching drive cylinder 5251, a drive rod 5252, a gear set 5253, a drive shaft 5254, a departure chain 5255, two pairs of hanger pushing components 5256, and hanger stopping components 5257.

[0079] The gear set 5253 includes the largest clutch gear 52531, the reversing gear 52532, and the drive gear 52533. The clutch gear 52531 is connected to the drive rod 5252 via a transmission assembly. Under the drive of the switching drive cylinder 5251, the drive rod 5252 can rotate in the horizontal direction, causing the clutch gear 52531 to move a certain distance toward or away from the main track 110.

[0080] When the drive rod 5252 rotates to its position in one direction, the clutch gear 52531 approaches the main rail 110 and meshes with the conveyor chain 1121 on the main rail 110. The conveyor chain 1121 is constantly rotating. Therefore, the conveyor chain 1121 drives the clutch gear 52531 to rotate, which in turn drives the reversing gear 52532 and the drive gear 52533 to rotate, and further drives the exit chain 5255 to rotate, driving the hanger to leave the station. When the drive rod 5252 rotates to its position in the other direction, the clutch gear 52531 moves away from the main rail 110 and disengages from the conveyor chain 1121 on the main rail 110. At this time, the clutch gear 52531 loses its power source, and the gear set 5253 and the exit chain 5255 stop running, thus stopping the exit. In addition, the moving distance of the drive rod 5252 can be very small, as long as the clutch gear 52531 and the conveyor chain 1121 can properly mesh and disengage.

[0081] The departure chain 5255 includes a belt 52551 with multiple evenly spaced mounting holes and multiple cylindrical teeth 52552 mounted on the belt 52551 via the mounting holes and connectors. The drive shaft 5254 has multiple grooves that match the cylindrical teeth 52552. Therefore, the gear set 5253 drives the drive shaft 5254 to rotate, and the drive shaft 5254 drives the cylindrical teeth 52552 embedded in the grooves to move circumferentially, thereby driving the departure chain 5255 to rotate. Furthermore, as... Figure 15 As shown, multiple cylindrical teeth 52552 are all located on the inner side of the belt 52551 ring. Therefore, the cylindrical teeth 52552 will not affect the first blocking member 5241 and the second blocking member 5242 located on the outer side of the belt 52551 ring.

[0082] also, Figure 15 Only a portion of the cylindrical teeth 52552 are shown as an example; in reality, multiple cylindrical teeth 52552 are evenly spaced within the belt loop 52551. For example... Figure 15 As shown, two pairs of hanger pushing members 5256 and hanger stopping members 5257 are fixedly mounted on the departure chain 5255 and can move with the departure chain 5255, thereby pushing the hanger to move. The hanger pushing member 5256 and hanger stopping member 5257 in each pair are spaced apart by a predetermined distance.

[0083] like Figure 20-21As shown, the hanger pushing component 5256 is fixed in the mounting hole of the belt 52551 by a connector and is located outside the belt 52551. Along the conveying direction D3 of the outgoing chain 5255, the upstream end of the hanger pushing component 5256 is the hanger pushing end 52561, which is hook-shaped with the hook facing outward from the belt 5251, and is used to hook the stabilizing frame 42 of the hanger 40 and push the hanger to move; the downstream end of the hanger pushing component 5256 is the guide end 52562, which is wedge-shaped, and is used to guide the stabilizing frame 42 of the hanger 40 to move to the outer surface of the hanger pushing component 5256 and be hooked by the hanger pushing end 52561.

[0084] Furthermore, the upper end of the hanger pushing member 5256 has an upwardly protruding blocking member pushing block 52563, which is used to push the second blocking member 5242 to rotate, thereby releasing the hanger in the notch of the release mechanism 524. Specifically, the blocking member pushing block 52563 is polygonal in shape, with one end away from the hanger pushing end 52561 being a wedge-shaped inlet end 52563a, the middle part being a straight segment 52563b, and the end closer to the hanger pushing end 52561 being a wedge-shaped outlet end 52563c.

[0085] Therefore, when the hanger reaches the blocking mechanism 524, the hanger pushes the first blocking member 5241 to rotate and reaches between the ends of the first blocking member 5241 and the second blocking member 5242. The first blocking member 5241 resets under the action of the first spring 52413, and the hanger is locked by the notch formed by the two opposing ends of the first blocking member 5241 and the second blocking member 5242. Then, when the hanger pushing member 5256 moves to below the second blocking member 5242, the blocking member pushing block 52563 at the upper end of the hanger pushing member 5256 contacts the pushing protrusion 52427 below the second blocking member 5242. The wedge-shaped lead end 52563a gradually squeezes the pushing block 52423, causing the second blocking member to... As 5242 rotates along the shaft, the second blocking end 52423 of the second blocking member 5242 approaches the exit chain 5255. At this time, the gap formed between the first blocking member 5241 and the second blocking member 5242 gradually opens. Then, when the abutting part enters the straight section 52563b, the hanger is no longer blocked by the second blocking member 5242. As the blocking member pushing block 52563 moves in the straight section 52563b, the hanger pushing end 52561 hooks the hanger's stabilizing block 42, dragging the hanger away from the gap. Finally, when the abutting part enters the wedge-shaped guide end 52563c, the second blocking member 5242 gradually resets under the force of the second spring 52425, thus completing the smooth release of the hanger.

[0086] like Figure 22As shown, the hanger stop member 5257 is also fixed in the mounting hole of the belt 52551 by a connector and is located outside the belt 52551 ring. Along the conveying direction D3 of the outgoing chain 5255, the downstream end of the hanger stop member 5257 (i.e., the end facing the hanger push end 52561) is the hanger stop end 52571. The hanger stop end 52571 is wedge-shaped, and its lateral outward protrusion from the belt 52551 is greater than the width of the stabilizing block 42 of the hanger 40, which is used to stop the hanger on the connecting rail 523. Because the connecting rail 523 is inclined, the hanger can slide down the connecting rail 523 by gravity, which may cause the hanger to reach the main rail 110 in advance. The hanger stop member 5257 is used to stop the hanger in this case, so that the hanger maintains the predetermined outgoing conveying speed.

[0087] like Figure 23-24 As shown, the exit mechanism 526 is connected to the main track 110. An exit guide module component 117 is installed at the lower mounting slot 1131 of the main track 110, corresponding to the outlet 5261 of the exit mechanism 526, to guide the hanger from the exit mechanism 526 onto the main track 10. The exit guide module component 117 is installed in the lower mounting slot 1131 of the mounting frame 113 of the main track 110, with track module components 114 at both ends. Figure 25 As shown, the exit guide module component 117 has a long, rectangular shape and includes an exit guide seat 1171 for mounting on the mounting frame. The exit guide seat 1171 has an arc-shaped guide groove 1172 in its center, and the exit mechanism's outlet 5261 is also arc-shaped. The arc-shaped guide groove 1172 connects with the arc at the outlet 5261, allowing the hanger to smoothly enter the main track 110 along the exit of the exit mechanism via the arc-shaped guide groove 1172. To ensure stable movement of the hanger, a protruding edge 1173 is provided within the exit guide groove. The exit guide seat 1171 is equipped with a mounting buckle 1174, which has a certain degree of elasticity. The exit guide seat 1171 is installed and fixed by pressing the mounting buckle 1174 into the corresponding mounting hole on the lower mounting groove 1131. The exit guide seat 1171 is hollow inside and has several crisscrossing reinforcing plates 1175, which can enhance the strength of the exit guide seat 1171.

[0088] like Figure 2 , Figure 25-26 As shown, a suction bridge rail 153 is also installed above the connection between the branch rail 120 and the main rail 110. This rail is used to separate the push rod component 1122 from the hanger when the hanger on the branch rail 120 leaves the station, and to allow the push rod component 1122 to flow back onto the branch rail 120.

[0089] The two ends of the bridging track 153 are respectively connected to the two ends of the U-shaped branch track 120 near the main track 110. The bridging track 153 is composed of several curved track segments and several straight track segments. In this embodiment, the bridging track 153 includes a first curved track segment 531, a first straight track segment 532, a second curved track segment 533, a second straight track segment 534, a third curved track segment 535, a fourth straight track segment 536, and a fifth curved track segment 537 connected in sequence. The straight track segments and curved track segments are connected by connecting components. Along the conveying direction D4 of the bridging track 153, the first curved track segment 531 is inclined upward, the first straight track segment 532 is approximately horizontal, the second curved track segment 533 is bent 180 degrees in the horizontal direction, the second straight track segment 534 is approximately horizontal, and the third curved track segment 535, the fourth straight track segment 536, and the fifth curved track segment 537 are all inclined downward.

[0090] The structure of the three straight track sections is the same as that of the bearing track 111, and will not be described again.

[0091] Although the three curved track segments bend in different directions and have different radii of curvature, their structural principles are the same. Therefore, the following explanation will take the first curved track segment 531 as an example.

[0092] like Figure 25 As shown, the first curved track segment 531 is composed of multiple curved splicing blocks 5310 spliced ​​together sequentially. The first curved track segment 531 is generally inclined upward. Along the conveying direction, the curvature of its first half and second half is different. The slope of the first half gradually increases and the slope of the second half gradually decreases, so that the connected first straight track segment 532 is set roughly horizontally.

[0093] like Figure 27-28 As shown, the curved splicing block 5310 has a first splicing surface 5311 and a second splicing surface 5312.

[0094] A pair of dovetail grooves 53111 are formed on both sides along the length direction of the first splicing surface 53111. Both dovetail grooves 53111 extend vertically and pass through upwards. The width of the bottom of the dovetail groove 53111 is greater than the width of the opening. A pair of protruding sliders 53131 are located at corresponding positions on the second splicing surface 5312. The shape of the sliders 53131 matches the shape of the dovetail grooves 53111, allowing them to be inserted from above and slide into the corresponding dovetail grooves 53111. Because the width of the bottom of the dovetail groove 53111 is greater than the width of the opening, the sliders 53131 are not easily dislodged after insertion. In other words, the first splicing surface 53111 of a curved splicing block 5311 can be inserted with the second splicing surface 53112 of an adjacent curved splicing block 53111, thereby sequentially splicing them into a curved conveyor track.

[0095] The first splicing surface 5311 and the second splicing surface 5312 are not parallel to each other, but form a certain angle, which is about 3° to 5°. Figures 29-30 The curved splicing block 5310 shown is located in the first half of the first curved track section 531 along the conveying direction. The projections of its first splicing surface 5311 and second splicing surface 5312 along the horizontal direction form a certain angle, so that the thickness of the upper end of the curved splicing block 5310 is less than the thickness of its lower end. Therefore, the first half of the first curved track section 531, which is spliced ​​from multiple curved splicing blocks 5311, bends upward and the slope gradually increases. In the second half of the first curved track section 531 along the conveying direction, the thickness of the upper end of the curved splicing block 5310 is greater than the thickness of its lower end. Therefore, the second half of the spliced ​​section tilts upward, bends downward and the slope gradually decreases.

[0096] In the second curved track segment 533, the projections of the first splicing surface 5311 and the second splicing surface 5312 of the curved splicing block 5310 along the horizontal direction have a certain angle, so that the thickness of one end of the curved splicing block 5310 along the length direction is greater than that of the other end. Therefore, the second curved track segment 533 formed by splicing is curved in the horizontal direction.

[0097] The upper end of the curved section 5310 has a support protrusion 5313, which has a through hole 53131 extending along the thickness direction of the curved section 5310 for installing reinforcing bars. The reinforcing bars pass through multiple through holes 53131 of the curved section 5310, thereby strengthening the load-bearing capacity of the curved track section.

[0098] A pair of hook-shaped flanges 5314 are formed at the lower end of the curved splice block 5310, and a bottom mounting groove 5315 is formed between the pair of flanges 5314 and the main body of the curved splice block 5310. The cross-sectional shape and size of the bottom mounting groove 5315 (the cross-section along the vertical direction in the figure) are consistent with the cross-sectional shape of the upper mounting groove 132 of the bearing rail 11.

[0099] In addition, the curved section 5310 has a pair of hexagonal holes 5316 extending along its thickness on both sides near the bottom, for the corresponding connectors to pass through when connected to the straight track section. The curved section 5310 also has multiple weight-reducing grooves and holes to reduce the overall structural weight, including square grooves in the middle of the first splicing surface 5311 and the second splicing surface 5312, and square holes next to a pair of flanges.

[0100] like Figure 29As shown, since the bottom of the curved splicing block 5311 has the aforementioned bottom mounting groove 5315, the bottom structure of the bridge rail 153 formed by splicing is consistent with the support rail and the main rail's bearing rail 111, and a conveyor chain 1121 can also be installed. Therefore, like the main rail 110 and the support rail, the bridge rail 53 can drive the push rod member 1122 to move along its extension direction via the conveyor chain 1121.

[0101] Therefore, when the push rod member 1122 pushes a hanger to the connection point between the branch rail 120 and the connecting rail 523, the hanger slides along the connecting rail 523 to the stop mechanism 524 to wait for exit, while the push rod member 1122 continues to move along the bridging rail 153, that is, the push rod member 122 and the hanger separate. Afterwards, the push rod member 122 moves along the bridging rail 153 to the other end of the branch rail 120, and the hanger exits at an appropriate time onto the main rail 110 and is transported by the main rail 110 to the next workstation.

[0102] like Figure 30 As shown, workstation 121 includes a workstation entry mechanism 1211, a workstation exit unit 1212, a ring rail 1213 connecting the workstation entry mechanism 1211 and the workstation exit unit 1212, and a vehicle lifting mechanism 1214, all mounted on a support rail 120. The bottom of the vehicle lifting mechanism 1214 has a processing station (not shown in the figure) for operators to use. An operating terminal 400 is located next to the processing station, allowing operators to confirm completion of processing and to perform corresponding operations if errors or omissions are found in previous processes.

[0103] The structure of the workstation entry mechanism 1211 is the same as that of the entry mechanism 151, and the structure of the workstation exit unit 1212 is the same as that of the rack exit unit 153, so they will not be described again.

[0104] The ring rail 1213 is also composed of the carrying rail 111. The difference is that the ring rail 1213 is set at an angle. The ring rail 1213 on the hanger can be transported by its own weight. Therefore, the ring rail 1213 does not have the chain conveyor 1122 and the push rod component 1122.

[0105] The vehicle lifting mechanism 1214 includes a plate chain assembly 2141 and a plate chain drive assembly 2142.

[0106] The plate chain assembly 2141 is used to drive the hanging bracket to move up and down. It is formed by connecting multiple link units 21410 end to end. Each link unit includes a load-bearing link for supporting the hanging bracket and a connecting link for connecting two adjacent load-bearing links. The load-bearing link and the connecting link are rotatably connected to each other, thereby splicing together to form the plate chain assembly 2141. The load-bearing link has an opening slot for the hanging bracket to be inserted and a limiting member for limiting the hanging bracket, so that the hanging bracket can move with the plate chain assembly 2141.

[0107] The plate chain drive assembly 2142 is used to drive the plate chain assembly 2141 to move. In this embodiment, the plate chain drive assembly 2142 is located at the outlet of the plate chain assembly 2141. It includes a geared motor, a drive wheel and multiple guide wheels. The plate chain assembly 2141 is tensioned on the drive wheel and multiple guide wheels. The guide wheels can guide the plate chain assembly 2141 to change direction, so that the plate chain assembly 2141 can form the actual required shape. The geared motor drives the drive wheel to rotate, thereby driving the plate chain assembly 2141 and its hanging bracket to move.

[0108] Therefore, after the hanger enters the ring rail 1213, it slides to the vehicle lifting mechanism 1214 by its own weight and is lowered to the processing station for processing personnel to process. After processing is completed, the processing personnel press the "Complete Processing" button through the operation terminal 400, and the vehicle lifting mechanism 1214 lifts the hanger to the workstation exit unit 1212 to wait for exit.

[0109] In addition, the suspended equipment 100 is equipped with multiple sensors for automated control.

[0110] like Figure 31 As shown, the multiple sensors include a push rod sensor 191, an entry rack reader 192, a diversion rack reader 193, an exit rack reader 194, a push element sensor 195, and a drive rod sensor 196.

[0111] The push rod sensor 191 is mounted on the main track 110 via a bracket, and is positioned upstream of the station entry mechanism 151 on the main track 110. Figure 31At position B1, a push rod member 1122 is used to sense and identify the push rod member 1122 that has arrived at that position. In this embodiment, the push rod sensor 191 is an infrared sensor. Since the widths of the push rod member 1122 and the hanger (width along the extension direction of the main track 110) are different, the push rod member 1122 and the hanger generate different signals when they pass the push rod sensor 191. Therefore, the hanger and the empty push rod can be identified based on the sequence of signals sensed. For example, sensing the push rod member, the hanger, and the push rod member in succession indicates that the hanger has been identified, and the next push rod member is the push rod member that moves the hanger; sensing two push rod members in succession, and the time interval between them is within a predetermined range, indicates that the next push rod member is an empty push rod.

[0112] The rack reader 192 for station entry is also located at position B1. It is installed on the main track 110 using the aforementioned identification module structure and is used to read the rack identification code of the rack arriving at that position. In this embodiment, the chip on the rack stores the rack identification code, and the rack reader 192 for station entry is the corresponding identification code reader.

[0113] The diversion rack reader 193 is installed upstream of each workstation 121 on the branch rail 120, that is... Figure 31 At position B3, the hanger identification code is used to read the hanger that has reached that position.

[0114] The exit rack reader 194 is mounted on the first mounting bracket 1521 and is located directly above the notch formed by the first blocking member 5241 and the second blocking member 5242 of the blocking mechanism. Figure 31 At position B4, the rack identification code of the rack at that position is read to determine whether there is a rack that is blocked (i.e., waiting to leave the station) in the gap.

[0115] The pusher sensor 195 is positioned on the first mounting bracket 1521 at a location away from the support rail 120, i.e. Figure 31 At position B5, there are a hanger push member 5256 and a hanger stop member 5257 for sensing the arrival of the hanger at that position.

[0116] In addition, each workstation 121 is equipped with an operating terminal for the processing personnel at that workstation 121 to operate. After the processing at the current workstation 121 is completed, the processing personnel press the "Processing Completed" button on the operating terminal to confirm the completion of the process and allow the rack to start leaving the station. If the processing personnel find problems in the previous processing or miss a certain process, they can also make corrections through the operating terminal. This situation will be explained in more detail below in conjunction with the settings of the management terminal 200 and the control host 300.

[0117] The structure and working principle of the hanging equipment 100 have been explained in detail above. The control logic of the management terminal 200 and the control host 300 will be explained in detail below in conjunction with these structures.

[0118] like Figure 1 As shown, the management terminal 200 includes a management information storage unit 201, a management-side communication unit 202, a subsequent process acquisition unit 203, a workstation real-time statistics unit 204, a workstation efficiency acquisition unit 205, a workstation allocation unit 206, a conveyor path planning unit 207, a fault handling unit 208, and a management-side control unit 209. In this embodiment, the management terminal 200 is a PC installed in the processing plant, which is connected to the control host 300 via fiber optic communication.

[0119] The Management Information Storage Department 201 stores various types of information required for processing, including: order information table, process sequence table, process-workstation correspondence table, real-time process information table, and real-time workstation information table.

[0120] Table 1 Order Information Table

[0121]

[0122] As shown in Table 1, the order information table stores the order number, customer company name, and detailed information of each order, including clothing type, order quantity, and various attribute information such as clothing color and size.

[0123] Table 2 Process Sequence Table

[0124]

[0125] As shown in Table 2, the process sequence table stores the total number of processes corresponding to each garment type, the process number of each predetermined process, and its sequence number.

[0126] Table 3. Workstation Correspondence Table for Processes

[0127] Process number Workstation number X1 1001，1002，1003 X2 2001，2002，2003 … … X10 10001，10002，10003 … …

[0128] As shown in Table 3, the process-workstation correspondence table stores the process number of each process and the corresponding workstation number of one or more workstations 121. That is, all the listed workstations 121 can be used to perform the process.

[0129] Table 4 Hanger Information Table

[0130] Hanger identification code Order number GJ001 DD001 GJ002 DD001 … … GJ008 DD003 … …

[0131] As shown in Table 4, the rack information table stores the rack identification code and corresponding order number for each rack. Before the rack is installed into the system, the operator selects the order number through the operating terminal and reads the rack identification code of each rack sequentially through the reader. The rack identification code is stored in correspondence with the order number. Then, the operator fixes the corresponding sheet on the rack and hangs it on a main track 110.

[0132] Table 5 Real-time Process Information Table

[0133] Hanger identification code Clothing status Completed process number In-process process number Process number to be completed GJ001 Processing completed X1-X10 - - GJ002 In progress X1-X3 X4 X5-X10 … … … … …

[0134] As shown in Table 5, the real-time process information table stores real-time process information during production, including the hanger identification code of each hanger and the real-time status of each process of the garment on that hanger. Taking the second row of Table 4 as an example, this hanger has completed processes X1-X3, is currently in process X4, and processes X5-X10 are pending completion.

[0135] Table 6 Real-time Workstation Information Table

[0136]

[0137] As shown in Table 6, the real-time workstation information table stores the real-time information of each workstation 121, including the workstation number of each workstation 121, the working status of the workstation 121, the number of racks currently in the workstation, and the processing efficiency of the workstation.

[0138] The management communication unit 202 is used to communicate with the control host 300, obtain the process status of each rack in real time from the control host 300, and send the subsequent processes and corresponding conveying paths to the control host 300.

[0139] The subsequent process acquisition unit 203 acquires the process numbers of the next few processes based on the process information received from the control host 300. In this embodiment, for ease of explanation, after receiving a message from the control host 300 that a process has been completed, the subsequent process acquisition unit 203 queries the process sequence table to acquire the process number of the next process.

[0140] The workstation real-time statistics unit 204 calculates the real-time number of racks awaiting processing at each workstation 121 (hereinafter referred to as the real-time rack count) and the total number of racks over a past period based on the sensing results. Specifically, for the real-time rack count, when a rack enters workstation 121, i.e., when the corresponding rack reader 193 reads the rack identification code and the corresponding workstation entry mechanism 1211 allows it to pass, the real-time rack count of the current workstation 121 is incremented by 1; when a rack completes the current process and the operator at the current workstation 121 presses the "Complete Processing" button on the operating terminal, the real-time rack count is decremented by 1. For the total number of racks, within a certain period, when a rack enters workstation 121, i.e., when the corresponding rack reader 193 reads the rack identification code and the corresponding workstation entry mechanism 1211 allows it to pass, the total number of racks at the current workstation 121 is incremented by 1, and after this period, the count is reset and restarted. In this embodiment, the total number of racks is counted every half hour.

[0141] The workstation efficiency acquisition unit 205 calculates the processing efficiency of each workstation 121 based on the total number of racks obtained by the workstation real-time statistics unit 204. Specifically, the total number of racks can be directly used as the processing efficiency, or certain calculations can be performed, such as calculating the corresponding total number of racks per hour as the processing efficiency.

[0142] The workstation allocation unit 206 obtains the workstation numbers of all corresponding workstations 121 according to the next process, and obtains the real-time rack count and processing efficiency of each workstation 121 based on the workstation number. Then, it allocates racks to workstations 121 according to the real-time rack count, processing efficiency, and predetermined allocation rules. In this embodiment, the allocation rules are as follows: racks are preferentially allocated to the workstation 121 with the fewest real-time rack counts; when the real-time rack counts of multiple workstations 121 are basically the same, racks are preferentially allocated to the workstation 121 with the highest processing efficiency; when the real-time rack counts and processing efficiency of multiple workstations 121 are roughly the same, racks are evenly allocated to these workstations 121, that is, the first rack is allocated to the first workstation 121, the second rack is allocated to the second workstation 121, and so on.

[0143] The conveying path planning unit 207 plans the conveying path from the current workstation 121 to the next workstation 121 based on the workstation number of the current workstation 121 and the workstation number of the next process workstation 121 assigned by the workstation allocation unit 206. In this embodiment, before setting up the hanging conveyor system 10, the engineer designs the distribution and connection relationship of the workstations according to the factory area and actual processing needs, and draws a process route diagram based on the distribution of the workstations and the predetermined process sequence. Then, based on the process route diagram, the optimal conveying routes between each workstation are listed and stored. Therefore, after determining the current workstation number and the workstation number of the next process, the conveying path can be obtained by searching the stored optimal conveying routes based on these two workstation numbers.

[0144] The fault handling unit 208 is used to handle data loss caused by a fault when the management terminal 200 resumes normal operation from a fault. There are two fault handling strategies: one is to obtain the current process information from the control host 300 and automatically complete the process information from the process recorded before the fault to the current process; the other is to distrust the current process information, return to the last process recorded before the fault, and then send the information of that process to the control host 300. The management terminal 200 will display corresponding prompts and selection boxes on its display device for administrators to choose which fault handling strategy to adopt.

[0145] When the management terminal 200 malfunctions and is unable to send instructions for subsequent processes to the control host 300, the processing personnel at the corresponding workstation 121, upon learning of this situation, can manually specify the next process for each rack through their operating terminal. The control host 300 then proceeds with the delivery according to the manually specified process and sends the current process information back to the management terminal 200 once the management terminal 200 resumes normal operation. Therefore, the impact of the management terminal 200 malfunction on production can be minimized.

[0146] In this embodiment, the management terminal 200 is a PC. Taking a power outage of the PC as an example, if the rack is performing process X3 before the power outage, the worker at that workstation, upon learning of the malfunction of the management terminal 200, can query the workstation information corresponding to the next process X4 through their operating terminal after completion, manually designate the next process as X4, and specify one of the workstations. The control host 300 then transports the completed rack to the workstation for the next process based on this information input by the worker.

[0147] When normal operation resumes on the PC, assuming the aforementioned rack is currently undergoing process X7, different actions will be taken depending on the manager's choice:

[0148] When the manager chooses to trust the current process information (Strategy 1 above), the management terminal 200 automatically updates the information of the rack in the real-time process information table, changes its "completed processes" to X1-X6, "processes in progress" to X7, and "processes to be performed" to X8-X10, and sends the relevant information of process X8 to the control host 300 for subsequent transport control.

[0149] When the manager chooses not to trust the current process information (Strategy 2 above), the management terminal 200 will send the last recorded process information back to the control host 300, that is, resend the information of process X3 to the control host 300, and the rack will be sent back to the workstation corresponding to process X3.

[0150] The management control unit 209 is used to control the operation of the above-mentioned units.

[0151] like Figure 1 As shown, the control host 300 includes a control information storage unit 301, a host-side communication unit 302, a rack entry control unit 304, a rack exit control unit 305, and a host-side control unit 306. In this embodiment, the control host 300 is an industrial control computer installed in the processing plant.

[0152] The control information storage unit 301 stores a table of subsequent process information.

[0153] Table 7 Information on Subsequent Processes

[0154] Hanger identification code Next process number Assign workstation number Conveying path GJ002 X5 5001 4001-Z01-Z02-5001 GJ003 X4 4002 3001-Z01-4002 … … … …

[0155] As shown in Table 7, the subsequent process table stores the process number of each hanger to be processed, the corresponding workstation number of the assigned workstation 121, and the planned transport path information. Due to the limited storage space of the control host 300, only information about the processes following the current process is stored. In this embodiment, for ease of explanation, the control host 300 only stores information about the next process. Taking the first row in Table 6 as an example, the next process for hanger GJ002 is X5, and its assigned workstation 121 is 5001, which is the first workstation 121 on the 5th branch rail 120. Its planned transport path is 4001-Z01-Z02-5001, meaning it exits from the workstation currently located on the 4th branch rail, is transported via the 1st main rail to the 2nd main rail, and then via the 2nd main rail to the 1st workstation on the 5th branch rail. After a process is completed, the control information storage unit 301 removes the process information for that hanger.

[0156] The host-side communication unit 302 is used to communicate with the management terminal 200, send real-time process information to the management terminal 200, and obtain information on subsequent processes from the management terminal 200 and temporarily store it in the subsequent process information table.

[0157] The rack entry control unit 304 controls the rack entry based on the information temporarily stored in the subsequent process information table. It includes an entry judgment unit 3041, an entry control unit 3042, a diversion judgment unit 3043, and a diversion control unit 3044.

[0158] The entry judgment unit 3041 determines whether the rack should enter the corresponding branch rail 120 based on the rack identification code read by the rack reader 192. Specifically, it makes a judgment based on the information in Table 7. If the number of the current branch rail is in the conveying path, it determines that the rack should enter the current branch rail.

[0159] When the entry control unit 3042 determines that the entry judgment unit 3031 is correct, it controls the entry mechanism 151 to release the current hanger, allowing the hanger to enter the corresponding branch rail. When the entry judgment unit 3031 determines that the entry is incorrect, the hanger continues to be transported along the main rail 110 to the next branch rail.

[0160] The diversion judgment unit 3043 determines whether the rack should enter the corresponding workstation 121 based on the rack identification code read by the diversion rack reader 193. Specifically, it makes a judgment based on the information in Table 7. If the number of the current workstation is in the transport path, it determines that the rack should enter the current workstation.

[0161] When the diversion control unit 3044 determines that the diversion judgment unit 3033 is correct, it controls the workstation entry mechanism 1211 to release the current rack, thereby allowing the rack to enter the corresponding workstation.

[0162] Furthermore, if there is no relevant path information in the subsequent process information table (e.g., in the case of a malfunction in the aforementioned management server 200), the rack entry control unit 304 will transport and control the entry to the next workstation according to the station number manually specified by the processing personnel. When there are multiple paths that can reach the designated workstation, such as reaching the workstation through two different nodes, the workstation will be entered at the node that is reached first.

[0163] After the rack completes the current process and the processing personnel at the current workstation 121 press the "Complete Processing" button, the rack departure control unit 305 controls the rack's departure from the station. It includes a departure start judgment unit 3051, a departure start control unit 3052, a departure stop judgment unit 3053, and a departure stop control unit 3054.

[0164] The departure start judgment unit 3051 determines that the departure is possible when the departure rack reader 194 reads the rack identification code, the push rod sensor 191 senses an empty push rod, and the drive rod sensor 196 does not sense the drive rod 5225. That is, when there is a rack at the stop mechanism 524, an empty push rod passes by the corresponding position on the main track 110, and there is no departure in progress at this time, it is determined that the departure of the current rack can be started.

[0165] When the departure start control unit 3052 determines that the departure start judgment unit 3051 is correct, it controls the departure unit 122 of the hanger to start, that is, controls the switching drive cylinder 525 to work, so that the clutch gear 52531 meshes with the conveyor chain 1121 of the main rail 110, thereby starting the departure of the current hanger.

[0166] After departure is initiated, the departure stop determination unit 3053 determines that departure should stop when the pusher sensor 195 senses the second pair of hanger pushers 5256 and hanger stoppers 5257. That is, when the first pair of hanger pushers 5256 and hanger stoppers 5257 reach the main track 110 and complete the departure of the current hanger, departure should be stopped.

[0167] When the departure stop judgment unit 3053 determines that the departure stop control unit 3054 is correct, it controls the switching drive cylinder 525 to work, so that the clutch gear 52531 is separated from the conveyor chain 121 of the main rail 110, thereby stopping the departure after the current hanger has completed the departure.

[0168] The host-side control unit 306 is used to control the operation of the above-mentioned units.

[0169] The structure and working principle of the hanging rack conveying system 10 have been explained in detail above. The following will describe the specific process of hanging rack conveying in this embodiment in conjunction with the above structure.

[0170] like Figure 32 As shown, based on the aforementioned rack conveying system 10, the process of moving a rack to a designated workstation 121 on the support rail 120 specifically includes the following steps:

[0171] Step S1-1: The staff specifies the order number and reads the identification code of the hanger through the reader. The identification code and the order number are stored together. The sheet to be processed is then fixed onto the hanger and the hanger is hung on the main track 110. Then, the process proceeds to step S1-1a.

[0172] Step S1-1a: Set k=1, that is, specify the first branch 120, and then proceed to step S1-2;

[0173] Step S1-2: The hanger moves along the main rail 110 to the upstream position of the kth branch rail 120. The hanger reader 192 reads the hanger identification code of the hanger at this point, and then proceeds to step S1-3.

[0174] Step S1-3: The station entry judgment unit 3031 determines whether the hanger should enter the current branch rail 120 according to the hanger identification code. If the judgment is no, proceed to step S1-3a; if the judgment is yes, proceed to step S1-4.

[0175] Step S1-3a: Set k = k + 1, that is, specify the next branch rail 120 along the conveying direction of the main rail 110, and return to step S1-2;

[0176] In step S1-4, the station entry control unit 3042 controls the station entry mechanism 151 to release the current hanger, thereby allowing the hanger to enter the current support rail 120, and then proceeds to step S1-4a;

[0177] Step S1-4a: Set m=1, that is, specify the first workstation 121, and then proceed to step S1-5;

[0178] Step S1-5: The hanger moves along the support rail 120 to the upstream position of the m-th workstation 121. The hanger identification code of the hanger is read by the hanger reader 193 at this point, and then the process proceeds to step S1-6.

[0179] Step S1-6: The diversion judgment unit 3043 determines whether the rack should enter the current workstation 121 based on the rack identification code. If the determination is no, proceed to step S1-6a; if the determination is yes, proceed to step S1-7.

[0180] Step S1-6a: Set m = m + 1, that is, specify the next workstation 121 along the conveying direction of the branch rail 120, and then return to step S1-5;

[0181] In steps S1-7, the diversion control unit 3044 controls the workstation entry mechanism 1211 to release the current rack, thereby allowing the rack to enter the current workstation 121 and then enter the end state.

[0182] In the above steps, if the hanger passes all the branch rails along the conveying direction without entering any of them, it continues to move along the circular main track and passes through each branch rail again. Similarly, if the hanger passes through all the workstations on the branch rails without entering any of them, it continues to move along the U-shaped branch rails, returns to the main track, enters the branch rail again along the circular main track, and passes through each workstation again.

[0183] Furthermore, since the support rails in this embodiment are all located on the same side of the main rail, the hangers that have not entered the workstation or are returning can be observed by the staff, and the staff can also manually remove the hangers for information verification, etc.

[0184] like Figure 33 As shown, after processing at workstation 121 is completed, the process for shipping the rack out of the workstation includes the following steps:

[0185] In step S2-1, the push rod component 1122 pushes the hanger to the connection position of the support rail 120 and the connecting rail 523, and then proceeds to step S2-2;

[0186] In step S2-2, the push rod component 1122 separates from the hanger, the push rod component 1122 continues to move along the bridging rail 153, the hanger slides along the connecting rail 523 to the blocking mechanism 524 and stops in the notch of the blocking mechanism 524. At this time, the hanger reader 194 for exiting the station senses the hanger here, and then proceeds to step S2-3.

[0187] In step S2-3, the push rod sensor 191 senses an empty push rod on the main track 110. At the same time, the hanger departure unit 152 is not started. The departure start judgment unit 3051 judges it as yes, and then proceeds to step S2-4.

[0188] Step S2-4: The outbound start control unit 3052 controls the hanger outbound unit 152 to start the outbound process, and then proceeds to step S2-5.

[0189] In step S2-5, the first pair of hanger pushing members 5256 and hanger stopping members 5257 move to the blocking mechanism 524 to release the currently blocked hanger, and then proceed to step S2-6.

[0190] In step S2-6, the hanger is pushed to the main track 110 by the first pair of hanger pushing members 5256 and hanger stopping members 5257. At this time, the empty push rod also reaches the position. The hanger moves to the empty push rod and then proceeds to step S2-7.

[0191] In step S2-7, the pusher sensor 195 senses the second pair of hanger pushers 5256 and hanger stoppers 5257, and the departure stop judgment unit 3053 judges it as yes, and then proceeds to step S2-8.

[0192] In step S2-8, the outbound stop control unit 3054 controls the hanger outbound unit 152 to stop working and then enters the end state.

[0193] In the above steps, after the push rod component 1122 is separated from the bracket, it continues to move along the bridging track 153 to the other end of the same branch track under the drive of the conveyor chain 1121, thereby enabling the automatic return and reuse of the push rod component 1122.

[0194] like Figure 34 As shown, based on the above-mentioned rack conveying system 10 and the specific processes of entering and exiting the station, in this embodiment, the process of conveying a rack according to a predetermined procedure so that the sheet material on it can complete all the procedures in sequence includes the following steps:

[0195] Step S3-1: The staff specifies the order number, reads the identification code of the hanger, hangs the hanger containing the sheet material into the main track 110, and then proceeds to step S3-1a.

[0196] Step S3-1a: Set k=1, that is, specify the first process, and then proceed to step S3-2;

[0197] Step S3-2: The management terminal 200 assigns a workstation to the k-th process and plans the transport path, and then proceeds to step S3-3;

[0198] In step S3-3, the management terminal 200 sends the identification code of the rack, the process number of the kth process, the corresponding workstation number and the conveying path to the control host 300, and then proceeds to step S3-4.

[0199] In step S3-4, the control host 300 receives the information of the kth process, transports the hanger to the corresponding workstation according to the information, and sends the status information to the management terminal 200, and then proceeds to step S3-5.

[0200] Step S3-5: The management terminal 200 receives the status information and updates the real-time workstation information table accordingly, and then proceeds to step S3-6.

[0201] Step S3-6: The processing personnel at this workstation process the sheets or semi-finished products on the rack and confirm the completion of the processing through the operation terminal, and then proceed to step S3-7.

[0202] Step S3-7: The control host 300 receives the processing completion signal and sends the processing completion status information to the management terminal 200, and then proceeds to step S3-8;

[0203] Step S3-8: The management terminal 200 receives the processing completion status information, updates the real-time workstation information table accordingly, and then proceeds to step S3-9.

[0204] Step S3-9: Determine whether k=10, i.e. whether all processes have been completed. If the determination is yes, proceed to the end state; if the determination is no, proceed to step S3-9a.

[0205] Step S3-9a: Set k = k + 1, that is, specify the next process, and then return to Step S3-2.

[0206] Through the above steps, the racks carrying the sheets or semi-finished products are sequentially transported to the workstations of each process, and all processes are completed in sequence. After that, the management terminal 200 can then transport the rack to the inspection station 122 through the control host 300 for inspection by the inspectors and finally packed and shipped out; if there are errors or omissions in a certain process after inspection, the clothing can be transported back to the corresponding workstation for reprocessing.

[0207] As Figure 35 shown, when the processing personnel at a workstation 121 find that there are problems with the previous process or a process has been missed, the corresponding processing flow specifically includes the following steps:

[0208] Step S4-1: The processing personnel at the workstation 121 of process Xn find that there are errors or omissions in the previous process. The processing personnel judge whether they can identify the corresponding process. If the judgment is yes, go to Step S4-4; if the judgment is no, go to Step S4-2.

[0209] Step S4-2: The processing personnel cannot judge which process is incorrect, specify the inspection station 122 through the operation terminal 400, and then go to Step S4-3.

[0210] Step S4-3: The control host 300 transports the rack to the inspection station 122 according to the station number of the specified inspection station 122, and then enters the end state.

[0211] Step S4-4: The staff judge that the processing of process Xm (m < n) is incorrect, query the station number of the workstation 121 corresponding to process Xm through the operation terminal 400, and then go to Step S4-5.

[0212] Step S4-5: The processing personnel specify one of the workstations 121 of process Xm through the operation terminal, and then go to Step S4-6.

[0213] Step S4-6: The control host 300 transports the rack back to the workstation 121 of process Xm according to the workstation number of the specified workstation 121, and then enters the end state.

[0214] In Step S4-3 above, the inspectors at the inspection station 122 conduct inspections. After judging the incorrect process, they also specify the workstation corresponding to the process through the operation terminal at the inspection station 122, and the control host 300 transports the rack to that workstation for reprocessing.

[0215] As Figure 36As shown, after the management terminal 200 malfunctions (e.g., loses power) and recovers from the malfunction, the specific handling process includes the following steps:

[0216] Step S5-1: The management terminal 200 displays prompts and selection boxes for administrators to choose processing strategies. When the administrator selects strategy one, the process proceeds to step S5-2; when the administrator selects strategy two, the process proceeds to step S5-5.

[0217] Step S5-2: The administrator selects Strategy 1 (trust current process information), and the management terminal 200 obtains the current process information of each rack from the control host 300, and then proceeds to step S5-3.

[0218] Step S5-3: The management terminal 200 updates the real-time workstation information table based on the acquired information, and then proceeds to step S5-4.

[0219] Step S5-4: The management terminal 200 sends the next process information of each rack to the control host 300 according to the updated real-time workstation information table, and then enters the end state.

[0220] In step S5-5, the administrator selects strategy two (distrust current process information). The management terminal 200 sends the next process information of each hanger to the control host 300 based on the last information in the real-time workstation information table before the fault, and then enters the end state.

[0221] Functions and effects of the embodiments

[0222] The rack conveying system provided in this embodiment includes a hanging device with multiple workstations, a control host, and a management terminal. The management terminal is communicatively connected to the control host and has a management information storage unit, a workstation real-time statistics unit, and a workstation allocation unit. Therefore, it can count the real-time number of racks in each workstation based on the real-time status information of each workstation obtained from the control host, and allocate the next process workstation to the rack based on the real-time number of racks and send it to the control host. The control host controls the hanging device to convey the rack to the corresponding workstation for processing according to the allocated workstation. Therefore, the rack conveying system of the present invention can balance the workload according to the real-time status of each workstation, avoiding some workstations from becoming bottlenecks in the system or being idle for a long time, and greatly improving the overall processing efficiency of the system.

[0223] Specifically, multiple sensors and readers are installed on the main rail and support rails of the hanging equipment. The workstation real-time statistics department counts based on the sensing results of the sensors and readers, the release status of the corresponding entry mechanism, and the confirmation of processing completion by the processing personnel through the operation terminal. This allows for a simple and reliable acquisition of the real-time number of racks at each workstation and the total number of racks over a period of time. The workstation efficiency acquisition department calculates the working efficiency of each workstation based on the total number of racks over a period of time. The workstation allocation department assigns the next process workstation to each rack based on the real-time number of racks, working efficiency, and predetermined allocation rules. Therefore, it can ensure a balanced load on each workstation and improve production efficiency.

[0224] Furthermore, engineers pre-designed the distribution of workstations based on the factory area and actual processing needs, and created a process flow diagram in conjunction with the product's process sequence. Based on the process flow diagram, the optimal conveying route between each workstation can be obtained. The management terminal also includes a conveying path planning department, which can retrieve the optimal conveying route based on the current workstation and the assigned next workstation, and send it to the control host, thereby further improving conveying efficiency.

[0225] Furthermore, the management terminal also includes a fault handling unit with two fault handling strategies. Each workstation is equipped with an operating terminal. When the management terminal malfunctions and temporarily loses control of the control host, the processing personnel at each workstation can use the operating terminal to query and manually designate the workstation for the next process step. The control host can then control the transmission based on the manually specified information, thereby minimizing the impact of the management terminal malfunction on production. After the management terminal recovers from the malfunction, the fault handling unit can automatically recover the data lost due to the malfunction and provides two processing strategies: trusting / distrusting real-time status information from the control host. Therefore, automatic data recovery is possible, and product processing quality can be guaranteed even in special circumstances.

[0226] Furthermore, when a worker at a workstation discovers an error in a previous process, they can use the operating terminal to query the workstation corresponding to that process and manually designate the current rack to be reworked at that workstation. Similarly, if a worker discovers a problem but cannot pinpoint the specific process, they can manually designate the current rack to be sent to the inspection station. Inspectors at the inspection station will then check and confirm the problematic process, and similarly, they can use the operating terminal to query and designate the corresponding workstation for rework. Therefore, the system in this embodiment also provides a method for instantly and quickly correcting erroneous processes, eliminating the need to collect all problematic products for unified inspection and rework. Instead, errors are corrected instantly within the production process, saving significant manpower and time.

[0227] The above embodiments are only used to illustrate specific implementations of the present invention, and the present invention is not limited to the scope of the description of the above embodiments.

[0228] In the above embodiment, the management terminal 200 is a PC set up in the factory. In an alternative, the management terminal 200 can also be a remote terminal or set up in the cloud, as long as it is connected to the control host 300.

[0229] In the above embodiment, the management terminal 200 is a PC and the control host 300 is an industrial control computer located near the hanging equipment 100. In an alternative, the management terminal 200 and the control host 300 can also be an integrated management server.

[0230] In the above embodiment, based on the large-scale processing situation of a large factory, the distribution of multiple workstations 121 is as follows: multiple workstations 121 on each branch rail 120 are used to perform the same process, and each branch rail 120 is used to perform different processes. Along the conveying direction of the main rail 110, the branch rails 120 are used sequentially for the next process. In an alternative, the workstations 121 can be distributed differently according to the actual processing needs of the processing plant. For example, for a small factory with a small processing volume, each branch rail 120 can be used to perform all or the main processes of a garment; or for a larger processing volume, multiple adjacent branch rails 120 are used to perform the same process. For different distribution scenarios, the conveying control logic is basically the same.
