Description

Technical Field

[0001] This invention belongs to the field of automobile manufacturing technology and relates to the handling of bolts, and more particularly to an automatic bolt tilting mechanism for handling and transferring discarded bolts removed from a vehicle. Background Technology

[0002] During the production and manufacturing of automobiles, the installation and removal of bolts are necessary. During bolt removal, it is usually necessary to collect the discarded bolts removed from the vehicle. Factories typically have bolt collection boxes where workers place the discarded bolts for collection and transport.

[0003] Currently, disassembled bolts need to be poured into small turnover boxes and then manually transported. Using smaller turnover boxes can reduce the weight of each box of bolts. However, this reduces the weight of each box of bolts, but it increases the frequency of changing boxes, increases the extra walking time for operators, and requires an additional operator to complete the task. This is time-consuming and labor-intensive. On the other hand, establishing an intelligent control conveyor line to automatically transport bolts requires a large investment in equipment, is technically challenging, and is difficult to maintain.

[0004] Utility model patent application number 202121325674.0 discloses a bolt handling and tilting trolley, including a body, a control lever, and a housing. A handle is fixedly connected to one side of the body, casters are fixedly connected to the bottom of the body, a foot-operated pump valve assembly is fixedly connected to the bottom of the body, a pump valve bracket is fixedly connected to one side of the body, a drain rod is fixedly connected above the foot-operated pump valve assembly, a spring is fixedly connected to the foot-operated pump valve assembly, a foot pedal is connected to one side of the pump valve bracket, and a roller is connected to the spring. When tilting bolts: First, when the bolts inside the housing need to be removed, the control lever is moved away from the housing. The control lever rotates around the center of the crossbar, aligning the boss of the guide plate with another slot of the indexing plate. Moving the control lever away from the housing further away from the housing causes the boss of the guide plate to engage with the other slot of the indexing plate. At this point, the unloading gate opens along with the guide plate. Stepping on one end of the foot pedal extends the telescopic rod of the foot-operated hydraulic cylinder, allowing the bolts inside the container to be tilted under the constraint of the hinge seat. Through the cooperation of the drain rod, oil pipe, foot-operated hydraulic cylinder, pin, pin bracket, bottom hinge, and foot-operated pump valve assembly, the extension of the hydraulic rod achieves the lifting and tilting of the bucket. This design allows for quick and easy unloading of the bolts inside the container, avoiding the need for frequent container changes when using small turnover boxes.

[0005] While the aforementioned bolt handling and tilting trolley can quickly and conveniently tilt the bolts out of the housing, the tilting process requires a series of actions, including operating the lever, aligning the guide plate's protrusion, and stepping on the foot pedal. This process still requires manual labor, which is frequent and complex, hindering the automatic, timely, and efficient tilting of bolts. Summary of the Invention

[0006] To address the technical problem in existing technologies where bolt tilting requires manual labor, and the frequent and complex manual operation leads to inefficiency in bolt tilting, this invention provides an automatic material box loading device.

[0007] To solve the above technical problems, the technical solution adopted by the present invention is as follows:

[0008] An automatic bolt tilting mechanism includes a frame and a bolt tilting box for placing bolts. It also includes a sliding guide rail mounted on the frame. The bolt tilting box is mounted on the sliding guide rail and can move along the direction of the sliding guide rail. A stopper is provided on the sliding guide rail, triggered based on the weight of the bolts inside the bolt tilting box. A storage box for storing bolts is provided on the unloading side of the sliding guide rail, and a traction device for pulling the bolt tilting box towards the unloading side is provided on the feeding side of the sliding guide rail. The traction device is connected to the bolt tilting box via a traction rope.

[0009] When the number of bolts in the bolt tilting box reaches the rated weight, the stopper releases the restriction on the bolt tilting box, and the bolt tilting box slides along the sliding guide rail towards the storage box; after the bolt tilting box slides down to the predetermined position, under the action of the traction rope, the bolt tilting box stops sliding down, and under the action of inertia, the bolts in the bolt tilting box tilt into the storage box.

[0010] Furthermore, the traction device includes a housing, inside which a guide rod is provided along the height direction of the housing, and a slider that can move along the axial direction of the guide rod is sleeved on the guide rod. One end of the traction rope is fixedly connected to the slider, and the other end of the traction rope is fixedly connected to the bolt tilting box after passing through a pulley block.

[0011] As the bolt tilting box slides along the sliding guide rail toward the storage box, the traction rope drives the slider to move upward on the guide rod. After the bolts are tilted, the slider moves up and down on the guide rod under the action of gravity, and the traction rope pulls the bolt tilting box upward along the sliding guide rail.

[0012] Furthermore, the weight of the slider is 4-5 kg.

[0013] Furthermore, a sliding sleeve is connected to the bottom of the bolt tilting box. The sliding sleeve is fitted on the sliding guide rail and can move along the axial direction of the sliding guide rail. A blocking protrusion is also provided at the bottom of the bolt tilting box.

[0014] The stopper includes a rotating rod hinged to the frame, the free end of the rotating rod contacting the blocking protrusion, and a counterweight at the other end of the rotating rod;

[0015] During use, the blocking protrusion at the bottom of the bolt tilting box abuts against the free end of the rotating rod, and under the action of the counterweight, it blocks the bolt tilting box from moving downward along the sliding guide rail. After the weight of the bolts in the bolt tilting box reaches the rated weight, the component of the weight of the bolt tilting box and the bolts along the sliding guide rail is greater than the resisting force of the rotating rod on the bolt tilting box. The bolt tilting box will then move downward along the sliding guide rail and drive the rotating rod to rotate.

[0016] Furthermore, a roller is provided at the free end of the rotating rod, and the roller abuts against the blocking protrusion.

[0017] Furthermore, the weight of the counterweight is 3-4 kg.

[0018] Furthermore, a stop arm is provided at the end of the sliding guide rail.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] In this invention, a stopper is provided on the sliding guide rail. The stopper is triggered based on the weight of the bolts in the bolt tilting box. When the weight of the bolts in the bolt tilting box reaches the corresponding requirement, the stopper fails, the bolt tilting box slides down, and the bolts are tilted into the storage box under the action of inertial force. The whole process does not require manual operation and can be automatically realized directly according to the number of bolts placed in the bolt tilting box. The whole process does not require human intervention and can realize automatic, timely and efficient bolt tilting. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings. Embodiments of the present invention include, but are not limited to, the following examples.

[0027] Example 1

[0028] This embodiment provides an automatic bolt dumping mechanism, the purpose of which is to collect, transport and dump the discarded bolts removed from automobiles to a certain place for centralized management.

[0029] The system includes a frame 7, a bolt tilting box 4, and a sliding guide rail 3. The frame 7 is mainly used to install other parts and provide installation locations. The bolt tilting box 4 is mainly used to hold bolts; bolts removed from the vehicle by workers can be directly placed on the bolt tilting box 4. The sliding guide rail 3 is mounted on the frame 7 and provides a track for moving the bolt tilting box 4, facilitating the direct movement of bolts to designated positions. A storage box 1 for storing bolts is provided on the unloading side of the sliding guide rail 3, and a traction device 6 for pulling the bolt tilting box 4 towards the unloading side is provided on the feeding side of the sliding guide rail 3. The traction device 6 is connected to the bolt tilting box 4 via a traction rope 5.

[0030] The bolt tilting box 4 is mounted on the sliding guide rail 3 and can move along the path of the sliding guide rail 3. The bolt tilting box 4 can be connected to the sliding guide rail 3 via a T-slot-T-connector (i.e., a T-connector is installed at the bottom of the bolt tilting box 4, a T-slot is provided on the sliding guide rail 3, and the T-connector is installed in the T-slot and can slide freely). Alternatively, the bolt tilting box 4 can be connected to the sliding guide rail 3 via a bushing fit. Specifically, a sliding sleeve 41 is connected to the bottom of the bolt tilting box 4, and the sliding sleeve 41 has a through hole that matches the cross-section of the sliding guide rail 3. The sliding sleeve 41 is fitted onto the sliding guide rail 3 through its through hole, and the bolt tilting box 4 can move freely along the trajectory of the sliding guide rail 3 together with the sliding sleeve 41.

[0031] A stopper 8 is provided on the sliding guide rail 3. The stopper 8 can be triggered to fail based on the weight of the bolts in the bolt tilting box 4, allowing the bolt tilting box 4 to pass smoothly through the stopper 8 and slide downwards along the sliding guide rail 3. To achieve the stopper 8 being triggered to fail based on the weight of the bolts, this embodiment provides a specific structure that uses a counterweight. That is, the stopper 8 includes a rotating rod 82, which is hinged to the frame 7 and can rotate freely around the hinge axis. One end of the rotating rod 82 is provided with a counterweight 83, the weight of which can be determined based on the weight of the bolt tilting box 4 and the rated weight of the bolts it holds. Preferably, the weight of the counterweight 83 is 3-4 kg. The other end of the rotating rod 82 is a free end. Under normal circumstances (when the bolts are placed in the bolt tilting box 4 by the worker), under the action of the counterweight 83, the free end of the rotating rod 82 contacts and abuts against the blocking protrusion 42 at the bottom of the bolt tilting box 4. Preferably, a roller 81 is provided at the free end of the rotating rod 82, and the roller 81 abuts against the blocking protrusion 42.

[0032] In use, the blocking protrusion 42 at the bottom of the bolt tilting box 4 abuts against the free end of the rotating rod 82. As the number of bolts increases, the weight of the bolts in the bolt tilting box 4 increases, and the total weight of the bolt tilting box 4 and the bolts it contains, as well as the component force in the direction of the sliding guide rail 3, gradually increases. When the increase reaches the rated weight and continues to increase, the component force of the weight of the bolt tilting box 4 and the bolts along the sliding guide rail 3 is greater than the resisting force of the rotating rod 82 on the bolt tilting box 4. The bolt tilting box 4 will move downward along the sliding guide rail 3 and drive the rotating rod 82 to rotate.

[0033] The traction device 6 includes a housing 61, within which a guide rod 64 is arranged along the height direction of the housing 61 and is fixedly installed inside the housing 61. A slider 63 is fitted onto the guide rod 64, and the slider 63 can move axially along the guide rod 64. One end of the traction rope 5 is fixedly connected to the slider 63, and the other end of the traction rope 5 is fixedly connected to the bolt tilting box 4 after passing through a pulley assembly 62. The pulley assembly 62 includes movable pulleys and fixed pulleys; the number and installation position of the pulleys can be selected according to the actual situation. As the bolt tilting box 4 slides along the sliding guide rail 3 towards the storage box 1, the traction rope 5 drives the slider 63 to move upward on the guide rod 64; after the bolts are tilted, the slider 63 moves up and down on the guide rod 64 under the action of gravity, and pulls the bolt tilting box 4 upward along the sliding guide rail 3 through the traction rope 5. Preferably, the weight of the slider 63 is 4-5 kg.

[0034] In addition, a stop arm 2 is provided at the end of the sliding guide rail 3. When the bolt tilting box 4 slides down to the position of the stop arm 2, it collides with the stop arm 2, and the bolt tilting box 4 stops moving downward. The bolts in the bolt tilting box 4 will continue to move forward under the action of inertial force and eventually tilt into the storage box 1.

[0035] The working principle of the automatic bolt tilting mechanism is as follows: when the number of bolts in the bolt tilting box 4 reaches the rated weight, the stopper releases the restriction on the bolt tilting box 4, and the bolt tilting box 4 slides along the sliding guide rail 3 to the storage box 1; after the bolt tilting box 4 slides down to the predetermined position, under the action of the traction rope 5, the bolt tilting box 4 stops sliding down, and under the action of inertia, the bolts in the bolt tilting box 4 tilt into the storage box 1.

[0036] The above are embodiments of the present invention. The above embodiments and specific parameters are only for clearly illustrating the inventor's invention verification process and are not intended to limit the patent protection scope of the present invention. The patent protection scope of the present invention is still determined by its claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention should also be included within the protection scope of the present invention.
