Description

Technical Field

[0001] The present invention relates to the field of automation in the chemical fiber textile industry, and in particular to a device for rectifying a wire box on an overhead crane. Background Art

[0002] In the field of automation in the chemical fiber industry, a wire box is loaded by an overhead rail and an overhead crane to transport a wire cake to a wire box processor, that is, a lifting box frame. After the overhead crane reaches the station position, the lifting box frame is lifted to jack up the wire box on the overhead crane to complete unhooking, then move forward, and finally the box frame descends. Then, a stacker grabs the wire box from the box frame and places it in the warehouse. The above process is a relatively good technical solution for storing and transporting wire cakes. However, during daily production, due to the wear of the guide wheels caused by the long-term operation of the overhead crane, inaccurate stopping positions after the overhead crane reaches the station, as well as the insufficient number of wire cake layers in the wire box and the deviation of the hanging position of the wire cake on the rod of the wire box, it is easy to cause the wire box to shift, and accidents such as the overhead crane derailing from the overhead rail and the wire box tipping over often occur. After the accident, it is necessary to manually hang the overhead crane back on the overhead rail and re-align the wire box on the box frame. The accident handling process has great potential safety hazards, is relatively cumbersome, laborious and time-consuming, resulting in serious waste of resources and reducing the automation production efficiency. Summary of the Invention

[0003] The present invention provides a device for rectifying a wire box on an overhead crane to solve the above technical deficiencies, which can keep the wire box on the overhead crane in a rectified state when cooperating with the lifting box frame to improve the safety of wire box transfer.

[0004] The present invention discloses a device for rectifying a wire box on an overhead crane, including a first rail and a lifting box frame. The lifting box frame is arranged on the first rail. An installation frame is arranged on at least one side wall of the lifting box frame. A swing arm is arranged on the installation frame. The swing arm is rotatably connected to the installation frame through a pin shaft. A pressing wheel is arranged at the top of the swing arm. A power mechanism is arranged on the installation frame. The power mechanism drives the swing arm to rotate around the pin shaft, and the swing arm drives the pressing wheel to push the wire box into the range of the lifting box frame.

[0005] The lifting box frame is a wire box processor, which is arranged on the first track and can move. The lifting box frame has been widely used in the industry and is also a known structure. It will not be repeated here, and the specific structure of the lifting box frame is not limited. The specific function of the lifting box frame is: moving on the first track, being able to lift and bear the wire box. In the process of the overhead crane moving with the wire box, the wire box will have a certain offset, tilt, etc., especially when the wire box is not full of wire cakes, the wire cakes will gather at the entrance of the wire box. The entrance of the wire box is located on one of the sides of the wire box, which will cause the wire box to be heavier on that side, and the opposite side will be tilted, etc., causing the overhead crane to stop inaccurately after arriving at the station, and the lower end of the wire box cannot be aligned with the lifting box frame, which is easy to cause a dumping accident during the unloading process. When the overhead crane carries the wire box and cooperates with the lifting box frame, under normal circumstances, the inlet of the wire box is always in cooperation with the same side of the lifting box frame, so the direction of the inclination of the wire box is basically the side opposite to the inlet of the wire box, so a mounting frame and a swing arm should be set on the side wall of the lifting box frame corresponding to the opposite side of the inlet of the wire box. Of course, a mounting frame and a swing arm can also be provided on one side or other side of the silk box inlet, and there is no limitation on this. During the rising process of the lifting box frame, the power mechanism can drive the upper end of the swing arm to move toward the inner side of the lifting box frame, and when it contacts the silk box, it can push the silk box into the range of the lifting box frame, so the lifting box frame can directly receive the silk box after it is raised, and ensure that the silk box is in a vertical state, and will not fall over, etc., which is highly safe. The axial direction of the pressure wheel can be parallel to the side wall of the silk box it contacts or pushes, so the pressure wheel can slide up and down on the side wall of the silk box, thereby ensuring that the lifting box frame is smoother during the rising process.

[0006] The power mechanism is a cylinder, the cylinder body and the mounting frame are rotationally connected by a pin, the telescopic end of the cylinder and the swing arm are rotationally connected by a pin, and the axial direction of the pin between the cylinder body and the mounting frame, the axial direction of the pin between the telescopic end of the cylinder and the swing arm, and the axial direction of the pin between the swing arm and the mounting frame are parallel to each other, and the three are arranged in a triangle. Through the reasonable design between the cylinder body and the mounting frame and the telescopic end of the cylinder and the swing arm, the swing arm can be swung during the telescopic process of the cylinder. The cylinder adopts a telescopic cylinder, that is, there are two cavities inside the cylinder body, which are connected by two high-pressure air pipes respectively. When one cavity is pressurized, the cylinder is extended, and when the other cavity is pressurized, the cylinder is shortened. Moreover, the process of cylinder extension and shortening will generate active force acting on the swing arm, so that the swing arm can actively move back and forth.

[0007] On the opposite two side edges at the upper end of the lifting box frame, inclined unfolding plates are provided, and the distance between the two unfolding plates gradually increases from bottom to top. The design of the unfolding plates has a certain rectifying effect on the wire box, reducing the requirements for the swing arm and the pressing wheel. Therefore, the swing arm and the pressing wheel only need to push and press the lower end of the wire box within the range of the upper end of the unfolding plate. When the lifting box frame continues to rise, the unfolding plate can push the lower end of the wire box to the middle part of the lifting box frame, which can reduce the swinging amplitude of the swing arm.

[0008] An optoelectronic induction switch is provided at the upper end of at least one unfolding plate. The optoelectronic induction switch is used to sense whether the wire box above the lifting box frame is within the range of the unfolding plate. A PLC control module is arranged inside the lifting box frame. The optoelectronic induction switch is arranged vertically upward. After the overhead crane arrives, if the inclined position of the wire box exceeds the unfolding plate, the optoelectronic induction switch can sense that there is a wire box above it. If the wire box does not incline beyond the unfolding plate, the optoelectronic induction switch will not sense that there is a wire box above it. When it senses that there is a wire box above, it proves that the wire box is severely inclined and the swing arm and the pressing wheel need to be used for auxiliary rectification. The optoelectronic induction switch transmits the signal to the PLC control module, and the PLC control module controls the cylinder to act to push and press the wire box to be rectified. The above scheme has higher safety, can control the action of the swing arm according to the detection, and reduces the waste of ineffective actions and energy consumption.

[0009] An overhead crane wire box rectifying device obtained by the present invention can rectify the inclined wire box before the lifting box frame receives it, ensure that the wire box can be stably placed on the lifting box frame after being unhooked from the overhead crane, has higher safety, and at the same time has high rectifying efficiency and fast response speed.

[0012] In order to further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0013] Embodiment 1:

[0014] As Figure 1 、 Figure 2As shown in the figure, the present invention discloses a device for rectifying a wire box of an overhead crane, which includes a first track 1 and a lifting box frame 2. The lifting box frame 2 is arranged on the first track 1. An installation frame 6 is arranged on one side wall of the lifting box frame 2. When the wire box 5 cooperates with the lifting box frame 2, the side where the installation frame 6 is located is the side opposite to the inlet of the wire box 5. A swing arm 7 is arranged on the installation frame 6. The swing arm 7 is rotatably connected to the installation frame 6 through a pin shaft. A pressing wheel 10 is arranged at the top end of the swing arm 7. A power mechanism is arranged on the installation frame 6. The power mechanism drives the swing arm 7 to rotate around the pin shaft, and the swing arm 7 drives the pressing wheel 10 to push the wire box 5 into the range of the lifting box frame 2. The lifting box frame 2 is the wire box 5 processor, which is a device existing for receiving the wire box 5 and driving the wire box 5 to move on the first track 1. Its specific structure will not be elaborated here and is not limited either. The installation frame 6 refers to a connecting frame body or connecting plate, which is used for assembling the swing arm 7, the power mechanism, etc. Its specific shape and structure are not limited. If the wire box 5 is a frame structure assembled by horizontal and vertical metal strip materials, the pressing wheel 10 should correspond to one of the vertical metal strip materials. Under the action of the swing arm 7, the pressing wheel 10 can push and press the vertical metal strip material to ensure that during the rising process of the lifting box frame 2, the pressing wheel 10 can always be in contact with the wire box 5. In the preferred state, the pressing wheel 10 can correspond to the vertical metal strip material in the middle part of the wire box 5. Of course, two swing arms 7 and pressing wheels 10 can also be arranged at intervals on the installation frame 6, corresponding to both ends of the same side of the wire box 5 respectively, so as to improve the stability during the rectification of the wire box 5. The first track 1 cooperates with the overhead track 3, so that after the overhead crane 4 runs to the station, the lifting box frame 2 can run to directly below the overhead crane 4 for receiving the wire box 5.

[0015] The power mechanism is a cylinder 8. The cylinder body of the cylinder 8 is rotatably connected to the installation frame 6 through a pin shaft. The telescopic end 9 of the cylinder 8 is rotatably connected to the swing arm 7 through a pin shaft. And the axial direction of the pin shaft between the cylinder body of the cylinder 8 and the installation frame 6, the axial direction of the pin shaft between the telescopic end 9 of the cylinder 8 and the swing arm 7, and the axial direction of the pin shaft between the swing arm 7 and the installation frame 6 are parallel to each other, and the three are arranged in a triangle. In the above scheme, during the contraction or extension of the cylinder 8, the swing arm 7 will rotate around the pin shaft between it and the installation frame 6 to realize the rectification of the wire box 5. Its power mechanism is not limited to the cylinder 8 and can be a push rod motor, an oil cylinder or other mechanisms that can realize reciprocating motion.

[0016] Inclined unfolding plates 11 are arranged on the opposite two side edges at the upper end of the lifting box frame 2. The distance between the two unfolding plates 11 gradually increases from bottom to top. The distance between the lower ends of the two unfolding plates 11 should be greater than or equal to the width of the corresponding end face of the received wire box 5 to ensure that the unfolding plates 11 will not affect the stability of the received wire box 5.

[0017] At the upper end of the two unfolding plates 11, there is an optoelectronic induction switch 12, and the optoelectronic induction switch 12 is used to sense whether the wire box 5 above the lifting box frame 2 is within the range of the unfolding plate 11. Its optoelectronic switch can directly sense the presence or absence of an object within a certain range. Of course, in other embodiments, the optoelectronic induction switch 12 can be provided at the upper end of the unfolding plate 11 on the side close to the pressing wheel 10.
