Description

A trolley device for a turnout of a power chain storage line Technical Field

[0001] The invention belongs to the field of power capacitor processing equipment, and in particular relates to a trolley device for a power chain storage line switch. Background Art

[0002] There are many specifications and models in the capacitor production process, and multiple storage lines need to be established. Cleaning machines automatically clean the oil stains on the outer surface of the semi-finished capacitors. Capacitors of different specifications and models wait in different storage lines to enter the next process. In the existing technology, the capacitor suspension trolley is pushed into the accumulation chain line. During the pushing process, the wheels of the suspension trolley often get stuck in the switch, causing the curved track to deform, requiring maintenance and troubleshooting. Correcting the track is time-consuming and labor-intensive, affecting production output. The main reason is that when the pusher head of the accumulation chain happens to be in the curved track area of ​​the switch, the trolley is pushed by the trolley cylinder. After moving, the pusher head is not fully stuck between the lifting catch and the stop catch. The pusher head is in any part of the trolley wheel, which jams the trolley and even derails the wheel. Other reasons are that the push rod spring of the trolley cylinder is easily damaged, or the limit block is too low and does not fully assist in pushing into place, which can cause the trolley to get stuck.

Furthermore, to simplify the drawings and facilitate understanding, in some figures, only one of the components with the same structure or function is schematically depicted or labeled. As used herein, "one" not only means "only one" but also "more than one."

[0052] The advantages and features of the present invention will become more apparent from the following description and claims.

[0053] Example

[0054] 1 and 2 , this embodiment provides a trolley device for a power-collecting chain storage line switch, which aims to build a new storage line trolley mechanism, increase the number of multi-specification capacitors to be cleaned, make up for the defects of the existing technology, solve problems such as the suspended trolley getting stuck at the switch, increase the power-collecting chain pusher head 8 and the electrical induction switch 11, improve the pneumatic circuit, optimize the trolley mechanism, prevent the trolley from getting stuck on the switch and the curved rail 5, reduce the downtime failure rate, and improve production efficiency.

[0055] Specifically, it includes: a power chain track 9, a travel track 10, a booster mechanism, a propulsion unit, and an induction control mechanism. The power chain track 9 and the travel track 10 are configured identically, with sequentially connected chain links. Both tracks include straight sections and branch curved sections, namely, straight and curved tracks 5. The travel track 10 is located below the power chain track 9. A downward-extending propulsion unit is located within the power chain track 9. The wheels of the suspended trolley to be pushed travel on the travel track 10. The propulsion unit pushes the wheels, thereby moving the suspended trolley.

[0056] Referring to Figures 3 and 4 , in this embodiment, a booster mechanism is located below the side of the straight section and also below the side of the running track 10. The booster mechanism can also be used to propel the suspended trolley. Specifically, the booster mechanism includes a fixed plate 2, a rodless cylinder 1, a cylinder slider 7, and a push rod assembly 4. The fixed plate 2 is located below the side of the straight section and serves as a frame for securing the rodless cylinder 1. The rodless cylinder 1 is mounted on the side of the fixed plate 2 adjacent to the suspended trolley (hereinafter referred to as the adjacent side). The rodless cylinder 1 has a square structure and offers several stroke options, ranging from 1800 to 2500, which are adaptively selected based on different distances. The cylinder slider 7 is slidably connected to the rodless cylinder 1 and is also located on the adjacent side of the rodless cylinder 1. It is controlled by the rodless cylinder 1 sliding forward and backward along the direction of the straight section. The push rod assembly 4 is also connected to the cylinder slider 7 and is located on the adjacent side of the cylinder slider 7. It moves forward and backward with the cylinder slider 7, thereby propel the suspended trolley.

[0057] Specifically, the push rod assembly 4 includes a mounting base 401, an elastic member, a pusher claw 403, a limit block, a first connecting member 404 and a second connecting member 405. The mounting base 401 is bolted to the cylinder slider 7 and serves as the base of the push rod assembly 4. The first connecting member 404 is installed at one end of the mounting base 401 in the forward direction, and a through hole is provided on the first connecting member 404. Here, the direction of travel of the suspension trolley is the forward direction, and the backward direction is opposite to the forward direction. The bottom end of the pusher claw 403 is rotatably connected to the first connecting member 404 via a pin shaft. The top end of the pusher claw 403 is provided with an inclined surface, which faces the input end of the accumulation chain track 9. The pusher claw 403 extends outward to the bottom of the walking track 10, thereby pushing the suspension rod of the suspension trolley to make it move. A gasket and a cotter pin are also provided at the pin shaft to fix the pin shaft. The second connecting member 405 is mounted on the mounting base 401, with space between it and the first connecting member 404. The second connecting member 405 is a lifting eye screw, with its threaded end threadedly connected to the mounting base 401. The elastic member is a tension spring 402, one end of which is connected to the lifting eye end of the lifting eye screw, and the other end of the tension spring 402 is connected to the middle section or top end of the pusher pawl 403, so that the tension spring 402 is arranged at an angle relative to the mounting base. Preferably, by lengthening the tension spring 402, the amount of expansion and contraction can be reduced, thereby increasing the service life and preventing frequent breakage of the tension spring 402. A stop block is located between the first connecting member 404 and the second connecting member 405, bolted to the mounting base 401, and closely attached to the pusher pawl 403. The tension spring 402 constantly applies an elastic force to the pusher pawl 403 toward the lifting eye screw, while the stop block abuts the pusher pawl 403 to prevent it from rotating toward the lifting eye screw. Preferably, the height of the limit block can be increased, the force on the limit block can be reduced, and the limit block can be prevented from being desoldered or deformed.

[0058] Preferably, connecting plates 3 are also provided at both ends of the boosting mechanism, and the connecting plates 3 include a first connecting plate and a second connecting plate connected together, the first connecting plate and the second connecting plate are vertically arranged, the first connecting plate is bolted to the adjacent side of the fixed plate 2, and the second connecting plate is bolted to the end of the rodless cylinder 1, thereby fixing the rodless cylinder 1.

[0059] In this embodiment, a stopper is also provided on the straight section, which blocks the trolley's forward movement by extending a plate. When the appropriate time is reached, the plate moves, allowing the trolley to continue moving. A branch track 6 is also provided on the curved track section of the branch track. This branch track 6 is equipped with a movable plate, a rotating shaft, a drive connecting rod, and a drive cylinder. Controlling the drive cylinder activates the drive connecting rod, which in turn drives the rotating shaft and movable plate to switch branch track 6, allowing the trolley to enter the lower track of the accumulation and release chain.

[0060] 1 , in this embodiment, the pushing unit is a stacking chain pusher head 8 , one every 1500 mm. Of course, the spacing between pusher heads is not a limitation here. The stacking chain pusher head 8 is used to further pull the suspended trolley to achieve movement.

[0061] 1 , the inductive control mechanism is located on one side of the branch track curved section and is used to detect the position of the accumulation chain pusher 8 to control the boost mechanism. Specifically, the inductive control mechanism includes a sensing component and a control component.

[0062] The sensing assembly, located on one side of the curved section of the branch track, monitors the position of the power chain pusher 8 in real time. It includes a sensing bracket 12 and a sensing switch 11. The sensing bracket 12 is connected to the power chain track 9, attached to the outside of the track, and serves to secure the sensing switch 11. The sensing switch 11 utilizes a laser photoelectric infrared reflective switch with a long detection range, making it suitable for monitoring the power chain pusher 8. When it senses the pusher, a signal is transmitted to the PLC controller, which in turn controls the rodless cylinder 1 to pause the push of the suspended trolley.

[0063] Wherein, referring to Figure 6, the control component includes a solenoid valve 13 and a throttle valve 14. The air inlet and outlet ends of the solenoid valve 13 are respectively connected to the pipeline of the rodless cylinder 1 to control the operation or standby of the rodless cylinder 1, and the operation can be forward or backward. The throttle valve 14 is arranged on the pipeline between the solenoid valve 13 and the rodless cylinder 1 to control the pushing speed of the rodless cylinder 1. The solenoid valve 13 adopts a double-electrically controlled three-position five-way solenoid reversing valve, and the middle position is closed. If the rodless cylinder 1 is in the pushing process, the induction switch 11 detects the push head signal, the solenoid valve 13 loses power, the valve core moves, the air supply stops instantly, the cylinder stops pushing the trolley, and waits for a few seconds. When the accumulation chain push head 8 is no longer at the curved rail 5, the trolley is pushed into the switch.

[0064] The workflow of this embodiment will now be explained. First, in this embodiment, it should be clarified that the power chain track 9 is located above the running track 10. A trolley is suspended below the running track 10 via a boom, and a booster mechanism is located on the side of the boom. When the trolley carrying capacitor products from the storage line enters the power chain, the stopper opens, releasing the trolley that had previously entered and rested at the stopper. At this point, the booster mechanism is located behind the trolley. When the signaling rod on the trolley touches the signaling rod, a signal is transmitted to the rodless cylinder 1. The piston of the rodless cylinder 1 operates, and the cylinder slide 7 slides forward, driving the pusher pawl 403 of the push rod assembly 4 to push the trolley's boom, thereby moving the trolley. Because the limit block can abut the pusher pawl 403 in the forward direction, the trolley's boom can be easily pushed. When the trolley reaches the junction of the straight section and the curved section of the branch track, the power chain pusher 8 pulls the trolley up and down, and enters the curved track 5. At the same time, the cylinder slide 7 of the rodless cylinder 1 moves backward, and when the pusher claw 403 touches the next trolley boom, the pusher claw 403 will rotate in the forward direction due to the action of the tension spring 402, passing through the inclined surface to facilitate the pusher claw 403 to pass the trolley boom. After passing the trolley boom, the tension spring 402 rebounds, causing the pusher claw 403 to automatically return to a perpendicular state with the mounting base 401.

[0065] More specifically, if the rodless cylinder 1 is pushing and the induction switch 11 detects that the push head appears in the branch curve section, it will send a signal to the PLC controller. The PLC controller will de-energize the electromagnetic coil of the three-position five-way reversing valve, and it will immediately be in the middle closed position, so that the piston of the rodless cylinder 1 stops pushing, and the pusher claw 403 stops pushing the trolley, making it paused. After waiting for a few seconds, the accumulation chain push head 8 leaves the branch curve section, and then continues to push the trolley into the junction of the straight section and the branch curve section, and then the push head at the back pulls the trolley to move in the curved track 5.

[0066] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments. Even if various changes are made to the present invention, if these changes fall within the scope of the claims of the present invention and their equivalents, they still fall within the scope of protection of the present invention.
