Description

Technical Field

[0001] This invention relates to a conveyor line for conveying product components, and more particularly to a carrier used on the conveyor line for supporting and transporting containers. Background Technology

[0002] To improve production efficiency, the manufacturing of multi-component products often requires the use of conveyor lines to transport the constituent components over long distances. The conveyor line structure includes a closed-loop track. In addition to the main track, several branch rails are also installed. A rotating track-changing mechanism is used between the branch rails and the main track to allow the carrier to change tracks between the main track and the branch rails. The branch rails create processing stations on their outer sides, allowing operators to complete the corresponding processes on the components at these stations.

[0003] Chinese patent document (authorization announcement number: CN223950087U) discloses a conveyor belt drive device for timely disconnection of power to rear vehicles when they are stacked. The structure includes a flexible drive belt with several protruding pushers. The vehicle includes a frame with a force-bearing rod hinged to it. The lower end of the force-bearing rod extends laterally towards the lower side of the frame. The pushers, driven by the drive belt, abut against the lower end of the force-bearing rod to move the vehicle forward. The key feature is that the lower end of the force-bearing rod extends obliquely towards the rear and lower part of the vehicle; a force-applying surface is formed at the front end of the pusher, the surface being inclined, with its upper end tilted rearward, and the surface abutting against the lower end of the force-bearing rod to apply force.

[0004] This drive system propels the vehicle along a track. To enable movement, the vehicle has traveling sections at both ends, spaced apart. Each traveling section has a front and a rear force-bearing rod. A power line is located under the track, with several protruding block-shaped pushers protruding from it. These pushers abut against the force-bearing ends of the force-bearing rods, propelling the vehicle along the track. When the vehicle is traveling normally on the main or branch rails, the front force-bearing rod typically bears the force. When changing tracks between the main and branch rails, the front force-bearing rod disengages from the corresponding power line; the rear force-bearing rod is then pressed against by a pressure member on the conveyor line, causing its force-bearing end to enter the trajectory of the pusher on the corresponding power line. The pusher abuts against the force-bearing end of the rear force-bearing rod, smoothly propelling the vehicle to change tracks. Sometimes, to achieve a large load capacity, the vehicle itself needs to be relatively long. To ensure the stability of the vehicle's movement on the track, two running gears are typically installed at the front and rear ends of the vehicle. Because the main power line under the main rail and the branch power line under the branch rail need to be separated, such long vehicles are prone to losing power during track changes and will remain at the track change position, which will affect the normal movement of other vehicles.

[0005] Furthermore, to adapt to the physical space within the workshop and the functional characteristics of the conveyor line itself, the main rails and branch rails require numerous curved designs. When the vehicle travels on the rails, it inevitably turns through these curved sections. For low-height vehicles, due to their low center of gravity, the centrifugal force experienced at standard speeds when turning through curved sections is insufficient to compromise vehicle stability. However, for taller vehicles, such as support-type vehicles, which have storage devices on them for categorizing and placing various components, some storage devices require multiple layers. This results in a larger overall height for the vehicle. The stability of such support-type vehicles when traveling through the curved sections of the rails cannot be guaranteed, and typically, the vehicle's speed on the rails must be reduced to meet stability requirements. Summary of the Invention

[0006] One technical problem this invention aims to solve is to provide a conveyor line support carrier that exhibits good stability when changing direction on the curved section of the track or when switching between the main rail and the branch rail. It can appropriately increase the carrier's travel speed on the track, thereby improving the conveyor line's efficiency in transporting components.

[0007] Another technical problem that this invention aims to solve is to provide another type of conveyor support vehicle that can effectively ensure the continuity of force when changing tracks or transitioning between different power lines, has good smoothness of movement, and will not affect the normal movement of other vehicles on the conveyor line. To solve the aforementioned technical problem, the present invention provides the following technical solution: a conveyor line support carrier for running on a track, having a connecting frame for supporting a storage device, characterized in that it comprises: The forward traveling part is used for traveling support on the track and is set on the lower side of the front end of the connecting frame. The forward traveling part is provided with a front force-bearing structure, and the force-bearing end of the front force-bearing structure is used to receive the thrust of the pusher on the power line. The rear traveling section is used for traveling support on the track and is located on the lower side of the rear end of the connecting frame. The rear traveling section is provided with a rear force-bearing structure, and the force-bearing end of the rear force-bearing structure is used to receive the thrust of the pusher on the power line. The connecting device is mounted on the connecting frame and is located between the front traveling part and the rear traveling part in the front-rear direction of the vehicle, forming a mating structure; The sliding support is provided with a connecting structure, which is movably engaged with the aforementioned mating structure. The force-bearing end of the rear force-bearing structure extends elastically to the outside of the pusher's running trajectory. By setting a pressing structure on the outside of the corresponding position of the track, the rear force-bearing structure is slidably pressed, so that the force-bearing end of the rear force-bearing structure extends into the running trajectory of the corresponding pusher to receive the pusher's thrust. The sliding support is used to interact with the track, and under the constraint of the track, the position of the connecting structure on the mating structure is adaptively adjusted when the vehicle changes direction on the track; the track, sliding support, and connecting device are used to counteract the tilting of the vehicle when it changes direction.

[0008] The connecting frame is generally used to support storage containers, typically storage baskets, which are directly placed and fixed on the upper surface of the connecting frame. To accommodate the distribution of various components, multiple storage spaces are arranged within the storage basket, usually with vertical tiers. This type of storage basket is generally suitable for placing footwear components, which are directly placed into their respective storage spaces. The conveyor line involved is adaptable to the transport of footwear components in the footwear manufacturing industry. Rollers are generally installed on the front and rear running sections, rolling on the support surface of the track to propel the vehicle. A flexible power line is required along the track, with several pushers installed on the power line. These pushers propel the vehicle along the track by contacting the force-bearing ends of the front and rear force-bearing structures. Upstream of the change-of-track position on the main and branch rails, pressure blocks or plates serve as pressing structures. Initially, the vehicle is stressed by the front load-bearing structure during the change. Midway through the change, the pressing structure applies pressure to the rear load-bearing structure, which then continues to bear the load until the change is successful. The load-bearing end of the rear load-bearing structure elastically extends outward from the corresponding pusher's trajectory. This can be formed by the elastic material of the corresponding load-bearing structure or provided by additional components such as springs or torsion springs. The sliding support can be a sliding buckle, forming a sliding fit with the entire track.

[0009] For dual-track systems, sliding supports extend between the two single rails to provide support for the vehicle. When the vehicle turns or changes direction on the track, the connecting structure on the sliding support slides on the mating structure to accommodate the vehicle's movement. The sliding support provides stabilizing force to the vehicle by interacting with the track, counteracting the centrifugal force generated by the vehicle during travel.

[0010] Furthermore, a connecting plate is provided on the bottom surface of the connecting frame, and the mating structure is formed on the connecting plate. The mating structure can be an elongated hole on the connecting plate or a groove-shaped body on the bottom surface of the connecting plate. To accommodate the movement of the sliding support on the mating structure, the elongated hole and the groove-shaped body are generally set as arc-shaped. The connection plate facilitates the formation of the mating structure, making processing convenient and facilitating the mating with the connecting structure.

[0011] Furthermore, the connecting plate is provided with an oblong hole, and the connecting plate is separated from the connecting frame. The oblong hole is arc-shaped, and the middle part of the oblong hole protrudes arc-shaped towards the rear traveling part. The connecting structure is movably inserted into the oblong hole, and the oblong hole forms the mating structure. By machining the oblong hole on the connecting plate, it is convenient for the connecting structure to slide appropriately within the oblong hole.

[0012] Furthermore, the connecting structure includes a connecting column fixed to the top of the movable support. A bearing is provided on the top side of the connecting column, and the bearing is loosely inserted into the oblong hole. An expanding pressure plate is provided on the connecting column, at least above the bearing. The outer diameter of the expanding pressure plate is larger than the width of the oblong hole, and the expanding pressure plate is located between the connecting plate and the connecting frame. The use of a rail bearing improves the smoothness of the sliding of the connecting structure within the oblong hole, and the sliding support has good adaptability to the vehicle's travel position. The expanding pressure plate enables the connecting structure to engage with the oblong hole, resulting in good connection stability within the oblong hole and facilitating the sliding support's support of the vehicle.

[0013] Furthermore, the sliding support includes a connecting body, and rollers are correspondingly provided on the front traveling part, the rear traveling part, and the connecting body. The rollers are vertically arranged and are used to support the track. The rollers on the connecting body also normally roll and support the track's support surface, thereby making the sliding support have good following ability to the vehicle and reducing the vehicle's power consumption during travel.

[0014] Furthermore, the front traveling section, rear traveling section, and connecting body have the same structure, all being columnar bodies. The sliding support has good compatibility with the track, which can effectively reduce the types of vehicle accessories and facilitate the preparation of the vehicle.

[0015] Furthermore, support wheels are correspondingly provided on the front traveling section, rear traveling section, and connecting body. The support wheels are horizontally arranged and are used for rolling contact with the side of the track. By setting up support wheels, the resistance encountered by the vehicle during travel can be effectively reduced, thereby reducing the power consumption of the vehicle during travel.

[0016] To accommodate the travel requirements of long-length vehicles, a central force-bearing rod is provided on the rear end of the sliding support. The force-bearing end of the central force-bearing rod extends elastically to the outside of the corresponding pusher's running trajectory. The central force-bearing rod is pressed together by the aforementioned pressing structure, allowing its force-bearing end to extend into the running trajectory of the corresponding pusher. By using the central force-bearing rod to receive power from the pusher on the upstream power line, the vehicle experiences consistent thrust during track changes, facilitating smooth track changes and preventing disruption to the normal travel of other vehicles on the track, thus ensuring good stability of the conveyor line.

[0017] Furthermore, a horizontally mounted sliding frame is hinged to the rear end of the sliding support. The width of the sliding frame corresponds to the width of the sliding support. The upper end of the central force-bearing rod is hinged to the middle of the sliding frame, and the lower end of the central force-bearing rod extends towards the rear-lower side of the sliding frame. Two ends of a torsion spring located at the hinge end of the central force-bearing rod act on the central force-bearing rod and the sliding frame, respectively. The sliding frame design limits the position of the central force-bearing rod, ensuring that the force-bearing end of the central force-bearing rod corresponds to the position of the pusher on the power line, allowing the pusher to apply force to the central force-bearing rod in a timely manner.

[0018] Furthermore, the connecting frame is a split structure, including a front frame and a rear frame. The two ends of a metal counterweight plate are respectively connected to the front and rear frames, and the connecting device is located on the bottom surface of the counterweight plate. The overall split structure of the connecting frame, through the use of the counterweight plate, lowers the overall center of gravity of the vehicle and effectively improves the load-bearing capacity of the connecting frame.

[0019] Compared with the prior art, the present invention has the following beneficial effects: By installing the aforementioned sliding support on the carrier, the sliding support can maintain contact with the track during the carrier's turning motion. The track supports the carrier through the sliding support, effectively counteracting the centrifugal force generated when the carrier turns on the track, ensuring stable and reliable carrier movement and reducing the likelihood of tilting. Because the carrier's stability is guaranteed, its travel speed on the track can be appropriately increased, thereby effectively improving the efficiency of the conveyor line. Due to the good stability of the carrier on the track, the height of the storage containers can be appropriately increased, effectively improving the carrier's volume ratio and increasing the single-load efficiency of components. Correspondingly, for a double-track system, the distance between the two single rails does not need to be too large, effectively reducing the size of the conveyor line, making the structure compact, and improving the space utilization within the workshop. Furthermore, the lateral dimensions of the front and rear traveling sections do not need to be too large.

[0020] By incorporating a central load-bearing rod on the sliding support, positioned within the gap between the front and rear traveling sections, the carrier achieves graded stress distribution during track changing. This effectively accommodates the track-changing requirements of long carriers, resulting in a large carrying capacity, smooth track changing, and no disruption to other carriers on the conveyor line, ensuring stable operation. Furthermore, the presence of the central load-bearing rod allows the front and rear traveling sections to be positioned at the front and rear ends of the connecting frame, providing stable support for the carrier.

[0025] Referring to the accompanying drawings, this conveyor line support carrier is generally used in shoe manufacturing production lines to achieve long-distance transport of various components in shoe products, allowing operators to complete the processing of each component at different processing stations along the conveyor line. The directional terms such as front, back, left, and right are based on the carrier's direction of travel. The conveyor line structure includes tracks, typically made of aluminum profiles, horizontally arranged, with support surfaces formed on the tracks through specific structural designs, generally horizontally aligned. The tracks include a main track and several branch rails. The main track has a closed-loop structure, while the branch rails have curved structures, with both ends facing the main track. A track-changing device, primarily a swing arm, is located between the end of each branch rail and the main track. The upper surface of the swing arm is at the same height as the support surface, creating a path for the carrier when track changing is required. In shoe manufacturing production lines, the track is a double-track structure, meaning it consists of two parallel, spaced-apart single rails. A power line is provided on the underside of the track, and the power line is set along the direction of the track. Several block-shaped pushers are protruding from the power line.

[0026] As shown in the figure, the main structure of this support-type vehicle is a connecting frame 100. A support plane is formed at the upper end of the connecting frame 100, and the object being placed is supported on this support plane. A front traveling section 200 is provided on the lower side of the front end of the connecting frame 100, and a front force-bearing structure is provided on the front traveling section 200. The front force-bearing structure is generally movably set on the front traveling section 200. The front force-bearing structure is a rod-shaped front force-bearing rod 201, which is hinged to the front traveling section 200 at its middle position. The lower end of the front force-bearing rod 201 extends obliquely downward and backward to form a force-bearing end. The pusher pushes the vehicle to move on the track by abutting against this force-bearing end. A rear traveling section 500 is provided on the lower side of the rear end of the connecting frame 100, and a rear force-bearing structure is provided on the rear traveling section 500. The force-bearing end of the rear force-bearing structure is used to receive the thrust of the pusher on the power line. A sliding frame 3 is hinged to the rear side of the rear traveling section 500. A pair of clamping plates 502 are integrally formed on the rear traveling section 500. The front end of the sliding frame 3 is hinged to the pair of clamping plates 502, allowing the sliding frame 3 to move horizontally. The clamping plates 502 limit the vertical movement of the sliding frame 3. The sliding frame 3 is cross-shaped, and its width corresponds to the spacing between the two monorails. Horizontal support wheels 2 are provided at both ends of the sliding frame 3. The support wheels 2 are used to position the sliding frame 3 in the horizontal direction by contacting the side of the rails. A rear force-bearing rod 501 is hinged at the middle of the sliding frame 3, forming a rear force-bearing structure. The upper end of the rear force-bearing rod 501 is hinged to the middle of the sliding frame 3, and the lower end of the rear force-bearing rod 501 extends obliquely downwards and backwards towards the vehicle, forming the force-bearing end of the rear force-bearing structure. A torsion spring is provided at the hinge point between the sliding frame 3 and the rear force rod 501. The two ends of the torsion spring act on the rear force rod 501 and the sliding frame 3 respectively. Under the action of the torsion spring, the force-bearing end of the rear force rod 501 is located outside the running trajectory of the pusher.

[0027] When the vehicle travels in a straight line on the track, it is mainly driven by the front force-bearing rod 201 receiving the thrust from the pusher. Under normal circumstances, the main power line on the underside of the main rail and the branch power line on the underside of the branch rail are set separately, with a gap between them. At the beginning of the vehicle changing track between the main rail and the branch rail, the front force-bearing rod 201 will disengage from the pusher. The rear force-bearing rod 501 is T-shaped, with protrusions on both sides of its lower end. By setting a pressure block on the track upstream of the track-changing position, the pressure block slides and presses against the protrusions on the rear force-bearing rod 501, causing the force-bearing end of the rear force-bearing rod 501 to extend into the running trajectory of the corresponding pusher to receive the thrust from the pusher, thereby realizing powered track changing of the vehicle and improving the smoothness of track changing. For relatively short vehicles, the arrangement of the front force bar 201 and the rear force bar 501 can meet the requirements for the vehicle to change tracks. However, for longer vehicles, simply setting the front force bar 201 and the rear force bar 501 is sometimes insufficient to meet the requirement of the vehicle to change tracks with power throughout the entire process. The vehicle can be pushed step by step by setting an intermediate force bar at the middle position in the front-rear direction of the connecting frame 100.

[0028] A connecting device is provided on the connecting frame 100. In the longitudinal direction of the vehicle, the connecting device is located between the front traveling part 200 and the rear traveling part 500. A mating structure is formed on the connecting device. The mating structure has a certain size to accommodate the sliding support 400 described below to adapt to the movement generated by the vehicle changing direction. The sliding support 400 is provided with a connecting structure, which is movably engaged with the mating structure.

[0029] The sliding support 400 interacts with the track. Under the constraint of the track, it allows the position of the connecting structure on the mating structure to be adaptively adjusted when the vehicle changes direction on the track, thus meeting the vehicle's track-changing requirements. The main purpose of the sliding support 400 is to ensure the stability of the vehicle when traveling on curved sections of the track, using the track, sliding support 400, and connecting device to counteract the lateral tilt of the vehicle when changing direction from straight to curved travel.

[0030] A connecting plate 300 is provided on the bottom surface of the connecting frame 100. The connecting plate 300 constitutes the main part of the connecting device, and the mating structure is formed on the connecting plate 300. Several connecting rods 302 are vertically fixed to the bottom surface of the connecting frame 100. The connecting plate 300 abuts against the lower end surface of the connecting rods 302, and the connecting frame 100, the connecting plate 300, and the connecting rods 302 are fixedly connected by fixing screws. Due to the presence of the connecting rods 302, the connecting plate 300 and the connecting frame 100 are separated. The connecting plate 300 is provided with an oblong hole 301, which penetrates the connecting plate 300. The oblong hole 301 is arc-shaped, and the middle part of the oblong hole 301 protrudes arc-shaped towards the rear traveling part 500. The connecting structure on the sliding support 400 is movably inserted into the oblong hole 301, and the oblong hole 301 forms the mating structure. The connecting structure includes a connecting post 305, which is fixed to the top of the sliding support 400. The sliding support 400 and the connecting plate 300 are movably connected by the connecting post 305 being intermittently inserted into the oblong hole 301. To improve the smooth movement of the sliding support 400 relative to the connecting plate 300, the top of the connecting post 305 has a reduced-diameter protrusion. A bearing 304 is fitted onto this reduced-diameter protrusion, and the bearing 304 is intermittently inserted into the oblong hole 301. Expanding-diameter pressure plates 303 are fitted and fixed on both the upper and lower sides of the bearing 304 on the protrusion of the connecting post 305. The outer diameter of the expanding-diameter pressure plates 303 is larger than the width of the oblong hole 301. The expanding-diameter pressure plates 303 and the bearing 304 are axially fixed to the connecting post 305 by fixing screws. Two expanded diameter pressure plates 303 are located on the upper and lower sides of the connecting plate 300 to achieve the snap-fit ​​between the connecting structure and the waist-shaped hole 301, so as to prevent the sliding support 400 from separating from the connecting plate 300.

[0031] The connecting frame 100 is a split structure, including a front frame 101 and a rear frame 104. Both the front frame 101 and the rear frame 104 are made of plastic. The two ends of the counterweight plate 102 are respectively connected to the front frame 101 and the rear frame 104. The counterweight plate 102 is generally made of aluminum alloy or iron. The connecting device is located on the bottom surface of the counterweight plate 102. A locking plate 103 protrudes from the middle of both sides of the counterweight plate 102, extending upwards. A latch is provided on the outer side of the container, into which the locking plate 103 fits snugly. The connecting plate 300 is a rectangular aluminum or iron plate, and its four corners are fixed to the center of the counterweight plate 102 via connecting rods 302.

[0032] The sliding support 400 includes a connecting body 402. The front traveling part 200, the rear traveling part 500, and the connecting body 402 have the same structure, all being columnar bodies. The connecting body 402 has a hollow structure, and the connecting column 305 passes through the top of the connecting body 402 from the inside, and is fixedly connected to the connecting body 402 by fixing screws. Rollers 1 are correspondingly provided on the opposite sides of the front traveling part 200, the rear traveling part 500, and the connecting body 402 in the left and right directions. These rollers 1 are arranged at the same height and are vertical. After the vehicle is assembled onto the track, these rollers 1 are all supported on the support surface of the track. When the vehicle moves on the track, the rollers 1 roll on the support surface. Support wheels 2 are provided on opposite sides of the front traveling section 200, the rear traveling section 500, and the connecting body 402 in the left-right direction. The support wheels 2 are located below the rollers 1 and are horizontally arranged. The support wheels 2 are used for rolling contact with the side of the track. For a double-rail track, the sliding support 400, the front traveling section 200, and the rear traveling section 500 are all slidably located within the gap between the two single rails. The support wheels 2 on the sliding support 400 are clamped by the opposing sides of the two single rails, thereby stabilizing the position of the vehicle when it changes direction on the track.

[0033] A central force-bearing rod 401 is provided on the rear end side of the sliding support 400. The structure of the central force-bearing rod 401 is the same as that of the rear force-bearing rod 501. The force-bearing end of the central force-bearing rod 401 extends elastically to the upper side of the running trajectory of the corresponding pusher. The protrusion on the central force-bearing rod 401 is pressed by the aforementioned pressing structure, so that the force-bearing end of the central force-bearing rod 401 extends into the running trajectory of the corresponding pusher. A horizontally arranged sliding frame 3 is hinged to the rear end of the connecting body 402. The width of the sliding frame 3 corresponds to the width of the sliding support 400, and the sliding frame 3 is T-shaped. The upper end of the central force-bearing rod 401 is hinged at the middle position of the sliding frame 3, and the lower end of the central force-bearing rod 401 extends toward the rear lower side of the sliding frame 3. The two ends of the torsion spring provided at the hinge end of the central force-bearing rod 401 act on the central force-bearing rod 401 and the sliding frame 3 respectively. This allows the vehicle to be set to a longer length, and the vehicle can smoothly change tracks by applying force to the middle force rod 401 and the rear force rod 501 in stages through the pushers on the power line.
