Description

Technical Field

[0001] The utility model relates to the technical field of hanging conveying systems, and particularly relates to a hanging conveying system. Background Art

[0002] The hanging conveying system is used in clothing, home textile, home furnishing and other production enterprises for the transportation, intelligent control and intelligent distribution of materials, thereby improving production efficiency.

[0003] For example, Chinese utility model patent CN200920318118.3 discloses a "clothing hanging system", which includes a closed-loop track, a closed-loop driving member is provided in the direction of the track, and a plurality of workstations are arranged at intervals in the direction of the track, each workstation corresponds to a clothing station, and each clothing station is used to sew each part of the clothes. During operation, this hanging system sends the carrier to different stations in sequence according to the preset clothing sewing sequence, and finally the cut fabrics are sewn into finished clothes. The structure of each workstation includes a curved guide rail, both ends of which extend toward the track, and both ends of the guide rail are movably provided with curved swing heads, and under the action of the power mechanisms respectively provided at the two ends of the guide rail, the swing heads extend out to overlap with the guide rail, or detach from the guide rail. The driving member generally uses a drive chain, and a plurality of drive structures are provided on the driving member. The drive structure is a drive rod fixedly connected to the driving member. The drive rod extends into the position of the ring rail. When the drive rod follows the movement of the drive chain, it will drive the carrier on the ring rail to move. The carriers of the existing hanging conveying system all run on the ring rail and need to be driven by the driving member. The driving member is always in a working state, regardless of whether there is a carrier on the ring rail, which is not energy-efficient. The driving member generally uses a drive chain. The drive chain needs to be installed on the guide rail and needs to be tensioned. The structure is complex and the installation is troublesome. Since the carrier is driven by the driving member, inertia rushes forward, resulting in failure to enter the station and double carriers leaving the station. In view of the defects of the above-mentioned existing hanging systems, a hanging system with a completely new structure is now developed. Utility Model Content

[0004] The utility model provides a hanging conveying system, in which driving mechanisms such as racks and chains are no longer arranged above the track. The powered vehicle moves on the track based on its own power, and does not need to be driven by a push rod under the rack and chain. The structure is simpler and the installation is faster. It also avoids the problems of inertial forward rush of the unpowered vehicle, frequent double vehicles, control errors, etc.

[0005] The utility model provides a hanging conveying system, comprising a track, a workstation is arranged on the side of the track, the inlet end and the outlet end of the workstation are detachably connected to the track through an entry mechanism and an exit mechanism respectively, the track is used for a vehicle to walk on it, the vehicle enters the workstation from the track through the entry mechanism, and enters the track from the workstation through the exit mechanism; an entry card reader is arranged in front of the workstation entrance, and an exit card reader is arranged at the workstation exit, and also includes a control system for controlling the operation of the hanging conveying system; the vehicle is a power vehicle, and the power vehicle has a power mechanism for driving it to walk.

[0006] The use of self-driven power carriers not only greatly simplifies the structure of the hanging conveying system and facilitates installation, but also greatly simplifies the design of the control algorithm. There is no need to consider how to avoid the problem of the same push rod pushing multiple carriers when the carrier leaves the station. Since the power carrier is self-driven, the problem of the carrier rushing forward due to inertia in the traditional system will not occur.

[0007] Preferably, the power vehicle has rollers riding on the track, and the power mechanism is a motor driving the rollers to rotate.

[0008] Preferably, the workstation comprises an entry branch rail and an exit branch rail, the entry mechanism is arranged at the end of the entry branch rail, and the exit mechanism is arranged at the end of the exit branch rail.

[0009] Preferably, the track and / or workstation is provided with a charging mechanism for charging the power vehicle.

[0010] Preferably, the input end of the station branch rail is equipped with a station full detection device for detecting whether the station branch rail is full. The control system controls the power vehicle to enter the station according to the signal of the station full detection device. If it is full, the workstation will no longer receive the power vehicle.

[0011] Preferably, the control system receives a signal from the exit card reader, which indicates that there is a powered vehicle waiting to exit the workstation exit. The control system determines that there are no other powered vehicles from the workstation exit to a certain length L upstream, and the control system controls the powered vehicle at the workstation exit to exit.

[0012] Preferably, the specific way in which the control system determines that there are no other powered vehicles from the workstation exit to a certain length L upstream is: the control system does not receive a signal from the entry card reader, which indicates that a powered vehicle has passed through the entry card reader, or the control system receives a signal from the entry card reader, but the powered vehicle needs to enter the workstation; or the control system receives a signal from the entry card reader, and the powered vehicle does not enter the workstation, and the control system calculates DV*t. If DV*t>L, there are no other powered vehicles from the workstation exit to a certain length L upstream, where D is the distance from the exit to the entry card reader, V is the operating speed of the powered vehicle, and t is the time period starting from the time when the powered vehicle passes through the entry card reader.

[0013] The power carrier of the utility model has its own power, omits the driving parts, and does not need to install the driving chain and driving rod, so the structure is simpler and the installation is faster. It also avoids the problems of inertial forward rush of unpowered carriers, double carriers, and control errors that often occur. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] like Figure 1 , 2As shown in Figures 5 and 6, the hanging conveying system includes a circular track 1 and a power carrier 2, and multiple workstations 3 are arranged outside the track 1. There are multiple power carriers 2, which can run along the track 1, enter the workstation 3 from the track 1, or leave the workstation 3 and enter the track 1. The power carrier includes a powered hanger, a hanging basket, etc., and can also include a powered cargo vehicle, or even a powered trolley with a non-powered hanger or hanging basket mounted on the bottom.

[0022] like Figure 4 As shown, the power carrier 2 includes a body 2.1, and a roller 2.2 is provided at the top of the body 2.1, and the roller 2.2 is connected to the body 2.1 through a connector 2.3. A driving mechanism is installed on the power carrier 2, and the driving mechanism drives the power carrier to move on the track by itself. The driving mechanism of this embodiment includes a motor and a rechargeable power supply (not shown in the figure), and the power supply provides power to the motor, and the motor drives the roller 2.2 to roll, thereby driving the power carrier 2 to run along the track 1.

[0023] The workstation 3 can be a sewing station or a preparation station. The preparation station is used for storing empty carriers and clamping the cut pieces onto the track. The sewing station is used to sew the cut pieces. The workstation can also be a station with other functions such as an inspection station and an ironing station. In order to facilitate charging the power supply of the power carrier, a charging mechanism can be set on the track or on one side of the track, and the power carrier 2 can be charged when it passes the charging mechanism. The charging mechanism can also be set at the workstation 3.

[0024] like Figure 3 , 6 As shown, the workstation 3 includes an entry branch rail 3.1 and an exit branch rail 3.2. An entry mechanism 3.3 is installed at the input end of the entry branch rail 3.1, and the entry mechanism 3.3 can be connected to or separated from the track 1. An exit mechanism 3.4 is installed at the output end of the exit branch rail 3.2, and the exit mechanism 3.4 can be connected to or separated from the track 1. The entry card reader 3.5 is installed in front of the entrance (the location where the entry mechanism overlaps the track is the entrance), and the exit card reader 3.6 is installed at the entrance of the exit actuator 3.4. The entry branch rail 3.1 and the exit branch rail 3.2 are connected by a lifting mechanism 3.9. The power vehicle enters the entry branch rail from the track 1 through the entry mechanism, slides down to the bottom of the entry branch rail, and is lifted to the exit branch rail by the lifting mechanism 3.9. It can be foreseen that the lifting mechanism 3.9 can be replaced by a lifting mechanism. The station entry branch rail 3.1 can also be directly connected to the station exit branch rail 3.2, or connected through an inclined rail, and the power vehicle can move from the station entry branch rail to the station exit branch rail by its own power. The workstation 3 is also provided with a touch panel 3.7 for human-computer interaction between the personnel of the workstation and the main computer 6, and the lifting button 3.8 sends a vehicle lifting signal to the main computer 6 through the touch panel 3.7.

[0025] like Figure 6As shown, the input end of the station entry branch rail 3.1 is equipped with a station entry full detection device 3.10 for detecting whether the carrier stored on the station entry branch rail 3.1 is full. If it is full, the carrier is refused to enter the station.

[0026] like Figure 6 As shown, the hanging conveying system also includes a station controller 3.11, and the station entry mechanism, the station exit mechanism, the station entry card reader, the station exit card reader, the station entry full inspection, the touch-screen tablet, and the lifting mechanism are all connected to the station controller 3.11, and the station controller 3.11 is connected to the main computer 6, and the main computer is installed with the hanging system control software. In this embodiment, the main computer, the station controller, etc. constitute a control system.

[0027] like Figure 2 , 3 As shown, the components of the workstation are all mounted on the workstation frame 3.12. The track 1 is connected to the main beam 5 through the hangers 4 arranged at intervals along the track direction, and the workstation frame 3.12 is also connected to the main beam 5.

[0028] The power vehicle 2 is equipped with an identifiable device, such as an RFID chip, an IC chip, a barcode, or a QR code. The entry card reader and the exit card reader are used to identify the identifiable device and send the identification information to the host computer. The entry card reader locates the position of the power vehicle on the track by identifying the power vehicle.

[0029] The exit control of power vehicle 2 is as follows:

[0030] After the workers at the workstation finish processing the cut pieces on a power carrier, the power carrier moves to the exit mechanism. After the exit card reader identifies the power carrier, it sends an exit request to the main computer. After receiving the information, the main computer allocates the power carrier to the corresponding workstation of the next process according to the principle of balancing the processing tasks of each workstation in the process. And judge whether the power carrier meets the exit conditions. If the exit conditions are met, it sends an exit command to the station controller of the workstation, and the station controller controls the exit mechanism to release the power carrier to exit.

[0031] Whether the exit conditions are met: There is no powered vehicle within a certain length L from the exit to the upstream. If the exit (the location where the exit mechanism overlaps the track) is point b, there is no powered vehicle in the ab section for a certain distance upward to point a. At this time, the powered vehicle at the exit mechanism can exit the station. The specific method for determining whether there is a powered vehicle within a certain length from the exit to the upstream is as follows: first determine whether there is a powered vehicle passing through the station entry card reader of the workstation. If no powered vehicle passes, or a powered vehicle passes but the powered vehicle enters the station, then there is no powered vehicle within a certain length from the exit to the upstream; if there is a powered vehicle and the powered vehicle does not enter the station, the starting time is when the powered vehicle passes through the station entry card reader of the workstation. After a period of time t, calculate the value of DV*t>L (the distance from the exit to the station entry card reader is D, and the running speed of the powered vehicle is V). When DV*t>L, it means that there is no vehicle within a certain length L from the exit to the upstream; when DV*t≤L, it means that there is a vehicle within a certain length L from the exit to the upstream. The specific value of L from the exit to a certain length upstream and the specific value of the time period t are determined according to the situation of the hanging conveying system. As long as it is ensured that the power vehicle running on the track and the power vehicle leaving the workstation will not collide at the exit, within the time period t, the workstation waits for the power vehicle leaving the station to complete its exit.

[0032] The entry control is as follows:

[0033] The power vehicle passes through the station entry card reader, and the station entry card reader sends the information of the power vehicle to the main computer through the station controller. The main computer determines (1) whether this workstation is the target workstation assigned by the power vehicle; (2) whether the station entry branch track is full. If both of the above conditions are met, the main computer sends an entry command to the station controller, and the station controller controls the station entry mechanism to connect with the track, and the power vehicle enters the station automatically, and then the station entry mechanism resets and separates from the track.

[0034] Embodiment 2:

[0035] The positioning method and the entry and exit control method of the power carrier are different from those in Example 1.

[0036] An identification code (such as a barcode or a QR code) is provided on the track 1 or on one side of the track 1, and an identification device is installed on the power vehicle 2. The power vehicle 2 locates its own position by reading the identification code. A communication module is also installed on the power vehicle 2 for transmitting information with the controller. The power vehicle 2 sends the read identification code to the controller, and the controller can locate the real-time position of the power vehicle.

[0037] Pit Stop Control:

[0038] When the power vehicle 2 runs to the station entrance and needs to enter the station, the controller controls the station entry mechanism 3.3 to move and connect with the track 1, and the power vehicle enters the workstation through the station entry mechanism.

[0039] Outbound Control:

[0040] When the power vehicle 2 runs to the exit branch track and needs to exit the station, the controller determines whether the power vehicle passing through the exit upstream of the exit on track 1 will collide with the exiting power vehicle. If there is no power vehicle colliding with it upstream of the exit, the power vehicle 2 on the exit branch track exits the station. If there is a power vehicle colliding with it upstream of the exit, the power vehicle on the branch track waits for a few seconds before determining whether there is a power vehicle colliding with it; or the power vehicle upstream of the exit waits for a few seconds before moving, so that the power vehicle on the exit branch track exits the station first.
