Unless otherwise defined, all terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that the conventional terms should be interpreted as having a meaning that is consistent with their meaning in the relevant art and this disclosure. The present disclosure is to be considered as an example of the invention and is not intended to limit the invention to the particular embodiments.
Example one
A conveying system hoister is applied to a suspension sorting and conveying system of a supermarket. The main track that hangs letter sorting system sets up by elevating usually, and the space below the main track divides into each workstation according to the function, and the workstation has operating personnel to carry out manual work and be equipped with the lifting machine and link up with the main track of top in order to carry into the main track with the goods bag upwards lifting of manual operation.
The conveyor system elevator of the embodiment shown in fig. 1-2 comprises a closed conveyor belt 1, a driving motor 2, an offside sensor 3 and an alarm device 5. The endless conveyor 1 is an endless conveyor arranged in a vertical plane, for example an endless conveyor chain or an endless conveyor flat belt or an endless triangular conveyor. The closed transmission belt 1 in the embodiment is an annular transmission chain, the driving motor 2 is in transmission connection with a driving chain wheel through a commutator, and the annular transmission chain is connected with the driving chain wheel. When the driving motor 2 drives the closed conveying belt 1 to rotate, the closed conveying belt 1 on one side of the driving chain wheel moves upwards, and the closed conveying belt 1 on the other side of the driving chain wheel moves downwards. Evenly being provided with a plurality of couples 11 of equidistant on the closed transmission band 1, being equipped with one on couple 11 and hanging the mouth, a plurality of couples all set up on closed transmission band 1 towards same direction for all be located with the couple 11 of one side closed transmission band 1 (lieing in same one side of drive sprocket promptly) hang the mouth towards the same, will hang the promotion side that mouthful all up in the following, will hang the mouth and all down one side and call the return side of closed transmission band. The offside sensor 3 is arranged towards the lifting side of the closing conveyor 1 and is higher than the joining position of the lifter and the main track. The engaged position refers to the position where the bags on the hook of the elevator are transferred from the elevator to the main track on the elevator. For example, the offside sensor 3 may be a photoelectric sensor arranged on the lift in the plane of rotation with the closing belt 1, with the detection direction facing the lifting side of the closing belt 1. The offside sensor 3 can be blocked from emitting light signals only when a goods bag is hung on the hook, so that the offside sensor can emit offside signals when detecting that the goods bag is hung on the hook. The alarm device 5 can be an acoustic alarm, an optical alarm, a wireless alarm and the like, and is installed on the elevator to give an alarm. In this embodiment, the alarm device who adopts is the alarm lamp, and as preferred, the alarm lamp can also have multiple colour to report to the police to different faults.
The offside sensor 3 can be directly electrically connected with the alarm device, and the offside sensor 3 sends an offside signal to the alarm device when detecting the cargo bag so as to send an alarm through the alarm device. In the embodiment, the alarm device is controlled by a special controller (not shown in the figure), so that more functions can be expanded and the alarm device is more intelligent. The controller is electrically connected with the offside sensor 3, receives an offside signal sent by the offside sensor 3, and controls the alarm device to give an alarm after receiving the offside signal.
The controller is also electrically connected with the driving motor to control the starting and stopping of the driving motor. As shown in fig. 3, the operation process of the elevator can be divided into three parts: starting process, running process and stopping process. And after the controller and the hoister are powered on, entering the starting process of the hoister. In the starting process, the controller sends a trial operation signal to the driving motor (namely, a communication unit of the driving motor), the driving motor performs trial operation after receiving the trial operation signal, and if the motor can normally operate, a feedback signal is sent to the controller through the communication unit of the driving motor to indicate that the driving motor can normally start. If the controller does not receive the feedback signal of the driving motor after sending the trial operation signal, the starting fault of the driving motor is indicated, and the driver outputs an alarm signal to the alarm device so as to control the alarm device to give an alarm to prompt a worker that the elevator is in fault. In the operation process of the elevator, the hook of the elevator drives the cargo bag to move continuously, and finally the cargo bag is driven to move to the joint position of the elevator and the main rail to transfer the cargo bag to the main rail. If the bag fails to be transferred to the main track, it will continue to rise on the lifting side of the closure conveyor 1 with the hook of the lift, detected when passing the offside sensor 3, which will send an offside signal to the controller. After the controller receives the offside signal, on one hand, the controller gives an alarm through the alarm device, and on the other hand, the controller sends a stop signal to the driving motor to control the driving motor to stop so as to prevent the elevator from being failed. When the driving motor is in operation, the communication unit of the driving motor continuously sends out a normal operation signal to the controller to indicate that the motor is in normal operation. And if the controller does not receive the normal operation signal fed back by the driving motor at the expected time in the operation process of the elevator, the controller controls the alarm device to alarm.
The elevator of this embodiment also includes a count sensor 4 provided on the other side (left side or right side) of the hook on the return side of the closed conveyor 1. The count sensor 4 in this embodiment also adopts photoelectric sensor to count sensor 4 installs on the side of couple one side on closed transmission band 1 for when the couple of return side returned from top to bottom, can cut the light signal who blocks photoelectric sensor and send thereby detected. In order to improve the detection precision of the counting sensor 4, an upper counting sensor 4 and a lower counting sensor 4 can be arranged along the height direction, and the two counting sensors 4 send out counting signals when detecting the hook. The controller is electrically connected to the count sensor 4 and counts and stores the number of times of lifting based on the count signal from the count sensor 4. For example, the controller adds 1 to the counted number of times of lifting after receiving the count signal from the count sensor 4 every time (for the elevator with two count sensors, the controller receives the count signal from each of the two count sensors), so that the number of times of lifting the cargo bag by the elevator is counted.
Furthermore, the controller can also pre-store a required lifting number as a reference, so that the elevator works in an intelligent continuous working state. After the number of times needing to be lifted is set, the number of times needing to be lifted is compared with the number of times needing to be lifted, when the number of times needing to be lifted is equal to the number of times needing to be lifted, the driving motor is controlled to stop driving the closed conveying belt, and the controller resets the stored number of times needing to be lifted after controlling the driving motor to stop driving the closed conveying belt. The controller compares the pre-stored times needing to be lifted with the updated times needing to be lifted, when the times needing to be lifted are larger than the times needing to be lifted, the controller indicates that the driving motor (namely the lifting machine) cannot be effectively stopped, and the controller gives an alarm through the alarm device.
The lifting machine of the embodiment further comprises an operation area 12 arranged on the lifting side of the closed conveying belt 1, and the operation area 12 penetrates through the upper portion and the lower portion, so that the hook 11 is not interfered when the closed conveying belt 1 is lifted upwards. The operation area is also provided with an outward operation opening, so that an operator of the workstation can conveniently hitch the cargo bag on the hoister. Preferably, a lighting device 121, an emergency stop switch 122 and a reset switch 123 are further provided in the operation area. The emergency stop switch 122 is electrically connected with the controller, and when the emergency stop switch is pressed, the controller can be triggered to control the driving motor to stop. The reset switch 123 is electrically connected to the controller, and when the reset switch 123 is pressed, the controller can be triggered to stop the driving motor when the closing conveyor belt runs to a specified position. The emergency stop switch 122 and the reset switch 123 can both control the driving motor to stop, and the difference between the two is that: the controller will stop the drive motor immediately after the scram switch 122 is pressed, and the controller will control the drive motor to stop after the closed transmission belt is run to a designated position after the reset switch 123 is pressed. For example, the reset switch can be used for stopping the hook in the operation process, so that the hook can be stopped at the position of a normal bag hanging in time. Promote work efficiency on the one hand, on the other hand prevents to appear falling the operational accident of package under the condition of hanging the package in succession to protection operation safety, simultaneously, makes the operation of hanging the package more stable, is difficult to fall the package. In the continuous operation scene of the conveying track, a hoist is required to continuously hang the bags (the continuous hanging in the embodiment means that the hoist lifts a plurality of cargo bags to the main track at a substantially uniform speed within a period of time), and the reset button is pressed to enable the hoist to stop the next hook to be hung to a specified position convenient for an operator to hang the bags. Therefore, the operation of hanging the bags can be carried out rapidly and safely by operators under the condition of continuous bag hanging, and the operation accidents of bag falling are prevented.
