Abstract
Description
Technical Field
[0001] This utility model relates to a hanging system, and more particularly to a sewing workstation in the hanging system for sewing textiles. Background Technology
[0002] The hanging system is a suspension system with a closed-loop ring track. Several sewing workstations are spaced apart along the outer side of the ring track, each forming a workstation equipped with a sewing machine to perform a specific sewing process on the textile. A flexible drive device, equipped with several pushing components, is located on the outer side of the ring track corresponding to its direction. To transport the textile, multiple carriers are also needed. These carriers clamp or hold the textile for transport. The carriers are typically equipped with rollers that rest on the ring track. Driven by the pushing components, the carriers carry the textile along the ring track, transporting it along a predetermined path to each workstation to complete the various processes.
[0003] In existing hanging systems, the sewing workstation structure includes a support rail, which is a single, integral structure. The support rail has an inlet and an outlet device, respectively, which facilitates the movement of textiles from the ring rail onto the support rail and vice versa. For small-sized textiles, the existing hanging system is perfectly adequate. However, for larger textiles such as quilts, duvet covers, and sheets, this structure results in relatively low work efficiency. Typically, the hanging system oversupplys the sewing workstation with textiles; in other words, multiple textile carriers are usually located upstream of the workstation on the support rail. Due to the large size of the textiles carried, textiles on adjacent carriers can become entangled, affecting the operator's sewing efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a hanging system sewing workstation that can effectively improve the work efficiency of the operator during the working process.
[0005] To solve the aforementioned technical problem, the present invention provides the following technical solution: a hanging system sewing workstation, wherein the hanging system includes a ring rail for unidirectional movement of the carrier, and the sewing workstation is located on the outer side of the ring rail along its direction, including an inlet support rail and an outlet support rail. The key feature is that there is a gap between the inlet and outlet support rails, and a closed-loop conveyor chain is provided at the gap. The conveyor chain is vertically arranged and used to transport the carrier from the outlet end of the inlet support rail to the inlet end of the outlet support rail. At least two separated support wheels are provided below the gap, supporting the conveyor chain from the inside, thereby forming a retention section of a certain length on the bottom side of the conveyor chain, providing retention space for at least two separated carriers. A workstation is provided outside the retention section, and the height of the retention section is adapted to the workstation.
[0006] The carrier travels in one direction on a circular track. Typically, one complete rotation of the carrier on the track completes the entire process. The height of the designated stopping point is not specifically limited; it is based on the average height of an operator, allowing the operator to easily retrieve the textiles carried on the carrier from the stopping point for sewing while seated at their workstation. However, it is certain that the stopping point is positioned lower than the entry and exit support rails. The conveyor chain is generally formed by hinged chain plates, and the attachment point on the carrier engages with the clamping interface between adjacent chain plates. Generally, it is not necessary to remove the carrier from the conveyor chain during textile sewing. The conveyor chain is driven by a drive motor, which moves the conveyor chain while the carrier carrying textiles is being transported. The drive motor does not operate for extended periods; it only starts briefly upon receiving instructions from the suspension system. These instructions are issued by combining information about the vehicle's position detected by sensors and card readers located at appropriate positions within the suspension system. These technologies are already present in existing suspension systems. Under normal circumstances, two vehicles carrying textiles will remain at the holding area, and these two vehicles will be kept as far apart as possible within the holding space.
[0007] Furthermore, the retention section is linear. Linear retention sections are easy to install, have a simple structure, and can well accommodate the retention of two separate vehicles.
[0008] Furthermore, a horizontally positioned support rod is provided at the location of the retention section, with two support wheels positioned at both ends of the support rod. The separation of the two support wheels is achieved through a single support rod, resulting in a simple structure and facilitating the formation of the retention section.
[0009] Furthermore, the inbound and outbound support rails are elevated by a bracket, with downward-extending uprights on the bracket. The support rod is fixed to the lower end of the upright. The support rod uses the bracket as its fixed foundation, which facilitates the construction of the support structure for the sewing workstation, and this support structure will not cause movement interference to the support wheels and conveyor chain.
[0010] Furthermore, the inlet end of the exit support rail is higher than the outlet end of the inlet support rail. This facilitates the construction of the sewing workstation and allows for the smooth movement of vehicles carrying textiles on the support rail.
[0011] Furthermore, the length of the entry support rail is greater than the length of the exit support rail. The exit support rail is a straight line with an incline, the exit end of the entry support rail is curved, and the rest of the entry support rail is a straight line with an incline. This spatial arrangement of the support rails allows the vehicle to move using its own weight, reducing the need for a power mechanism and simplifying the structure of the sewing workstation.
[0012] Furthermore, two sets of distribution mechanisms are installed upstream of the exit end of the entry support rail, with a gap between them. Each distribution mechanism includes two opposing front and rear distribution plates, with their adjacent ends protruding movably onto the upper side of the entry support rail. The gap between the adjacent ends of the front and rear distribution plates is adapted to accommodate a roller on a single vehicle. The front distribution plate is located upstream of the rear distribution plate, which is connected to the power mechanism. This distribution mechanism allows for the sequential release of vehicles, facilitating the transport chain to move vehicles to their designated positions. Moreover, a full-station sensor can be installed at the rear distribution plate to provide feedback on vehicle accumulation at the corresponding workstation to the hoisting system, enabling the hoisting system to optimize the vehicle's travel path.
[0013] Furthermore, a belt drive mechanism is provided on the outer side of the exit support rail. This belt drive mechanism provides power for the vehicle to exit the station, compensating for the relatively short exit support rail which prevents the vehicle from automatically sliding out of the station, thus improving the vehicle's exit efficiency.
[0014] Furthermore, in the direction of travel of the vehicle on the ring track, the inlet end of the entrance branch rail is located downstream of the outlet end of the exit branch rail. This allows the dwell position to be set close to the work station, so that the operator basically does not need to run during operation, but only needs to turn their body, which can effectively improve the operator's work efficiency.
[0015] Compared with existing technologies, this utility model has the following advantages: In this sewing workstation, the spatial arrangement of the conveyor chain, with a retention section formed at the lower end of the chain, effectively accommodates the retention of carriers carrying textiles, facilitating the operator's work and effectively ensuring work efficiency. The retention section can reserve space for at least two carriers to be arranged separately. Through the design of the retention section's dimensions, effective separation between carriers can be achieved, preventing textiles from becoming entangled and facilitating the operator's individual handling and sewing of textiles. At least two carriers can remain at the retention section at a time, ensuring good continuity of the operator's work and further improving work efficiency. Attached Figure Description

[0020] Referring to the accompanying drawings, this sewing workstation is mounted on a hanging system. One hanging system typically corresponds to multiple sewing workstations 2. Each sewing workstation 2 forms a work position, with a workbench 4 placed outside the work position. A functional machine 5, such as a sewing machine, quilting machine, or ironing equipment, is installed on the workbench 4. Generally, one sewing workstation 2 corresponds to one process of the textiles transported on the carrier 7. Figure 1 The diagram only shows a simplified structural diagram of the hanging system. The hanging system involved has the same structure as existing hanging systems and is considered prior art. The hanging system requires the operation of multiple carriers 7. Each carrier 7 has a clamping part and a traveling part. The traveling part is generally a roller, and the clamping part is used to clamp large-format textiles. Figure 1 The diagram shows the structure of the suspension system, which mainly includes a ring rail 1. Rollers in the carrier 7 rest on the ring rail 1, allowing the carrier 7 to travel in one direction and enter the target sewing workstation 2. Multiple sewing workstations 2 are arranged along the outer side of the ring rail 1, with intervals between adjacent sewing workstations 2.
[0021] The structure of this sewing workstation 2 includes an inlet rail 21 and an outlet rail 22. The inlet rail 21 and the outlet rail 22 are not connected as a whole, but have a gap between them. A closed-loop conveyor chain 3 is provided at the gap. The conveyor chain 3 is vertically arranged, and the carrier 7 is moved across the gap by the conveyor chain 3. The conveyor chain 3 is used to transport the carrier 7 from the outlet end of the inlet rail 21 to the inlet end of the outlet rail 22.
[0022] This sewing workstation 2 is suspended by a bracket 6. Two parallel, downward-extending uprights 8 are fixed to the bracket 6. A horizontally positioned support rod 9 is bridged at the lower end of the two uprights 8. The support rod 9 is generally horizontal, and two support wheels 10 are rotatably mounted at both ends of the support rod 9. Of course, there can be more than two support wheels 10. The conveyor chain 3 is formed by hinged chain plates end to end. A clamping interface is formed between adjacent chain plates, which is biased towards the outside of the conveyor chain. The clamping interface is used to clamp the rollers of the carrier 7, thereby realizing the attachment and conveying of the carrier 7. The lower ends of the two uprights 8 extend into the lower side of the notch. The support wheels 10 support the conveyor chain 3 from the inside, thereby forming a retention section of a certain length on the bottom side of the conveyor chain 3. The retention section is generally straight, that is, the conveyor chain 3 is arranged in a straight line between the two support wheels 10. The retention section provides retention space for at least two separated carriers 7, and the length of the retention section can be determined by the required spacing between the two support wheels 10. The height of the retention section is determined by the length setting of the upright 8 and the fixed position of the support rod 9 on the lower end side of the upright 8, and the height of the retention section is adapted to the work position.
[0023] In addition to the two support wheels 10, an infeed device 12 and an outfeed device 13 are respectively provided at both ends of the notch on the bracket 6. The conveyor chain 3 passes through and is supported on the infeed device 12 and the outfeed device 13. The infeed device 12 allows the carrier 7 to enter the clamping interface of the conveyor chain 3 from the exit end of the infeeding support rail 21, and the outfeed device 13 allows the carrier 7 to enter the infeeding end of the outfeeding support rail 22 from the conveyor chain 3. Both the infeed device 12 and the outfeed device 13 are provided with drive sprockets. One of the drive sprockets can be connected to the drive motor, or both drive sprockets can be connected to the drive motor. If two drive motors are provided, both drive motors work simultaneously. A pawl can be provided at the clamping interface of the conveyor chain 3. The teeth of the drive chain engage with the insertion holes on the chain plate. Under the action of the teeth, the pawl will disengage from the clamping interface, allowing the rollers on the carrier 7 to smoothly enter and exit the clamping interface.
[0024] Figure 2 , 3As shown, the inlet end of the exit track 22 is higher than the outlet end of the inlet track 21. The length of the inlet track 21 is greater than the length of the exit track 22. The exit track 22 is a straight line with an incline, while the outlet end of the inlet track 21 is curved. The outlet end of the inlet track 21 extends horizontally and also has a vertical height change. This spatial arrangement at the outlet end is designed to facilitate the smooth movement of the vehicle 7 on the inlet track 21. The rest of the inlet track 21 is a straight line with an incline, and the inlet end of the inlet track 21 is at a higher position.
[0025] Two sets of distribution mechanisms 11 are provided upstream of the exit end of the entrance support rail 21, with a gap between them. This gap is generally used to hold multiple vehicles 7. Alternatively, only one vehicle 7 can be held within this gap, allowing for the release of vehicles 7 one by one. Each distribution mechanism 11 includes two opposing front and rear distribution plates, both positioned along the travel direction of the vehicle 7. The adjacent ends of the front and rear distribution plates movably protrude above the entrance support rail 21, and the gap between their adjacent ends is adapted to accommodate a roller on one vehicle 7. The front distribution plate is located upstream of the rear distribution plate, which is connected to a power mechanism. The upstream end of the front distribution plate is generally hinged to the entrance support rail 21, and a spring can be installed between the downstream end of the front distribution plate and the entrance support rail 21, causing the downstream end of the front distribution plate to protrude upwards towards the entrance support rail 21. The front shift plate can also be connected to a power mechanism such as a cylinder drive. The front shift plate will not obstruct the movement of the rollers. After passing the front shift plate, the rollers will enter the gap between the front and rear shift plates. Under the action of the power mechanism, the upstream end of the rear shift plate can sink into the entry support rail 21, thereby causing the target vehicle 7 to move downstream.
[0026] A belt drive mechanism 14 is provided on the outer side of the exit branch rail 22. The belt drive mechanism 14 has a transmission belt and is generally powered by a drive device on the ring rail 1 through a set of meshing gears. Alternatively, a drive motor can be used to move the transmission belt. A pushing member is protruding on the transmission belt, which pushes the carrier 7, allowing the target carrier 7 to smoothly enter the ring rail 1 from the exit branch rail 22.
[0027] In the direction of travel of the vehicle 7 on the ring track 1, the inlet end of the entrance branch track 21 is located downstream of the outlet end of the exit branch track 22. Therefore, the vehicle 7 enters the entrance branch track 21 from the downstream side of the ring track 1 and enters the ring track 1 from the exit branch track 22 from the upstream side.
