Heavy duty impact resistant roller tube conveyor

Abstract

The utility model discloses a heavy load anti-impact carrier roller pipe conveyor which is provided to solve the problem of large impact force of the carrier roller pipe on the existing carrier roller conveyor during the receiving process, which leads to deformation of the equipment or damage of the pipe body. The heavy load anti-impact carrier roller pipe conveyor comprises a transverse transfer device and a receiving mechanism. The receiving mechanism is used to receive the carrier roller pipe and make the carrier roller pipe roll down to the feeding end of the transverse transfer device. The carrier roller pipe is conveyed to the destination by the transverse transfer device. The receiving mechanism comprises a receiving plate. The receiving plate is inclined from the receiving side from top to bottom to the feeding end of the transverse transfer device to realize the rolling of the carrier roller pipe onto the transverse transfer device. The heavy load anti-impact carrier roller pipe conveyor with the structure of the utility model bears the gravity of the carrier roller pipe by the transverse transfer mechanism and the receiving plate when the carrier roller pipe enters the transverse transfer mechanism. When the carrier roller pipe falls, it rolls. Therefore, the impact force on the transverse transfer mechanism is small, and the carrier roller pipe itself is not easy to be damaged.

Description

Technical Field

[0001] This utility model relates to the technical field of idler tube production equipment, specifically to a heavy-duty, impact-resistant idler tube conveyor. Background Technology

[0002] In existing technologies, a pipe cutting machine is used to cut idler roller tubes to obtain the required length. The cut idler roller tubes are then transferred to the next process by a conveyor. Due to the heavy weight of the idler roller tubes, the impact force during the process of the tubes falling from the cutting machine to the conveyor is significant, causing considerable stress on the conveyor and potentially leading to equipment deformation or tube damage. Furthermore, idler rollers come in various specifications, with vastly different tube diameters and lengths, making it difficult for traditional conveyors to accommodate different sizes. Because the idler roller tubes are cylindrical, they are prone to rolling and stacking during transport, causing jams or disordered arrangement. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing idler roller conveyors, which suffer from large impact forces during material receiving, leading to equipment deformation or pipe damage. This invention provides a heavy-duty, impact-resistant idler roller conveyor.

[0004] The technical problem of this utility model is solved by the following technical solution: A heavy-duty impact-resistant idler tube conveyor includes a transverse transfer device and a receiving mechanism. The receiving mechanism is used to receive the idler tube and make it roll onto the feed end of the transverse transfer device. The transverse transfer device then transports the idler tube to its destination. The receiving mechanism includes a receiving plate that is inclined from top to bottom towards the feed end of the transverse transfer device from the receiving side to realize the idler tube rolling onto the transverse transfer device. The discharge side of the receiving plate is at the same height as the inlet end of the transverse transfer device. The receiving mechanism also includes a support frame and at least two adjustable support components. The adjustable support components include adjustable support rods. One end of the adjustable support rod is hinged to the lower surface of the receiving plate, and the other end is threaded and located in a through hole on the support frame. Adjusting nuts that are threaded to the adjustable support rods are provided on both the upper and lower sides of the support frame. The tilt angle of the receiving plate is adjusted and fixed by adjusting the nuts. The adjustable support components also include a connecting shaft, a locking nut, and a support base. Two connecting ears with connecting ear through holes are fixedly provided on the support base. One end of the connecting shaft is threaded and located between the two connecting ears. The connecting shaft passes through the connecting ear through holes and the support rod through holes. The locking nut is threaded to the connecting shaft and locked in place. The support base is fixedly connected to the lower surface of the receiving plate, thereby realizing the hinged connection between one end of the adjustable support rod and the lower surface of the receiving plate. A buffer pad is provided on the receiving plate, covering the surface of the receiving plate; or the tilt angle of the receiving plate is 15°–60°. It also includes a longitudinal transfer device, in which the conveying components of the longitudinal transfer device are arranged perpendicular to the running direction of the conveying components of the transverse transfer device, and the feed end of the longitudinal transfer device is connected to the discharge end of the transverse transfer device. The lateral transfer device is a chain conveyor. Multiple sets of guide plates are provided on the chain plate of the chain conveyor. Each set of guide plates includes at least two guide plates. The guide plates are arranged in parallel along the running direction of the chain plate, so that the space between each adjacent guide plate is formed to accommodate the idler roller tube. The upper part of one side surface of the guide plate is provided with a clearance chamfer, which faces the feed end of the transverse transfer device; A buffer pad is provided on the receiving plate, which covers the zipper plate on the surface of the receiving plate. An avoidance stop is provided on one side of the zipper plate covered by the buffer pad. The size and spacing of the avoidance stop are adapted to the width and spacing of the guide plate, and the guide plate can pass through the avoidance stop. A transfer mechanism is provided between the longitudinal transfer device and the transverse transfer device. The transfer mechanism includes a transfer plate. One end of the transfer plate is connected to the discharge end of the transverse transfer device and fixedly connected to the tail end of its frame. The other end is connected to the feed end of the conveying component of the longitudinal transfer device. The upper surface of the transfer plate is inclined from top to bottom from the transverse transfer device side to the longitudinal transfer device side. The discharge side of the transfer plate is at the same height as the conveying component of the longitudinal transfer device. The longitudinal transfer device includes two chain drive mechanisms, with the chains of the two chain drive mechanisms arranged in parallel. The distance between the two chains is adapted to the diameter of the idler tube to form a space to accommodate the idler tube. Multiple connecting plates are installed between two chains.

[0005] The heavy-duty impact-resistant idler tube conveyor with this utility model has a receiving mechanism that is inclined towards the feed end of the transverse transfer mechanism. Therefore, the idler tube is supported by the receiving plate before entering the transverse transfer mechanism. Since the idler tube rolls onto the conveying components of the transverse transfer mechanism, its weight is shared by the transverse transfer mechanism and the receiving plate when it enters the transverse transfer mechanism. It rolls when it falls, so the impact force on the transverse transfer mechanism is small and the idler tube itself is not easily damaged. Attached Figure Description

Detailed Implementation

[0009] The structure of this utility model will be described in detail below with reference to specific embodiments.

[0010] like Figure 1-6 As shown in the figure, the heavy-duty impact-resistant idler roller tube conveyor of this utility model embodiment consists of a receiving mechanism 1, a transverse transfer device 2, and an electrical control mechanism. The receiving mechanism connects with the tube cutter, and the idler roller tube rolls off the tube cutter onto the receiving mechanism 1, then enters the feed end of the transverse transfer device 2, where it is transferred to the vicinity of the destination.

[0011] The receiving mechanism 1 includes at least a receiving plate 7, which is inclined to connect with the conveying component of the transverse transfer device. The inclined direction of the receiving plate is from the pipe cutter side to the transverse transfer device side. To facilitate adjustment of the inclined angle of the receiving plate and increase its impact resistance, it is preferable to also provide at least two adjustable support components 6. Each adjustable support component 6 includes a support base 5, an adjustable support rod 10, a connecting shaft 11, and a locking nut 12. One end of the adjustable support rod 10 is hinged to the support base 5, and the other end is threaded. The hinged connection between the support base and the adjustable support rod is as follows: one end of the adjustable support rod has a support rod through hole, and two connecting ears are provided on the support base, each with a connecting ear through hole. The end of the adjustable support rod with the support rod through hole is located between the two connecting ears. The connecting shaft passes through the connecting ear through hole and the adjustable support rod through hole and is locked by the locking nut to obtain the hinged connection structure. Each adjustable support component 6 is connected to the lower surface of the receiving plate through the support base. Alternatively, no support base can be provided, and the connecting ears of each adjustable support component can be directly fixedly connected to the lower surface of the receiving plate. A support frame 9 is fixedly installed below the receiving plate. The threaded end of the adjustable support rod passes through the support frame 9. Adjusting nuts are provided on both the upper and lower sides of the support frame 9. The adjusting nuts are used to adjust the distance and tilt angle between the support frame and the receiving plate, so that the receiving plate and the support frame are tilted and the tilt angle is fixed. The receiving plate tilts from top to bottom from the receiving side to the transverse transfer device side in the running direction of the transverse transfer device. The tilt angle is fixed by locking nuts and connecting shafts. The tilt angle is preferably 15°–60°. Usually, one end of the support frame is fixedly installed on the frame of the transverse transfer device, and the other end is detachably and movably connected to the receiving plate through support components. In this embodiment, two sets of adjustable support components are provided, each set including five adjustable support components, which are arranged along the tilt direction of the receiving plate. Ideally, a buffer pad 21, such as a rubber pad, is installed on the receiving plate to provide cushioning. The buffer pad covers the receiving plate and a portion of it is located above the conveying component of the transverse transfer device. The high end of the receiving plate is used to connect with the material support mechanism 20 of the pipe cutter to receive the rolling idler tubes from the material support mechanism, and its low end connects to the conveying component of the transverse transfer device. With the above structure, the idler tubes roll from the material support mechanism 20 of the pipe cutter onto the receiving plate of the receiving mechanism 1. Since the receiving plate is inclined and connected at the same height as the material support mechanism, the idler tubes can fall smoothly onto the receiving plate and then roll from the receiving plate onto the transverse transfer device. During this process, the idler tubes are supported by the receiving plate and have a certain friction during their rolling. After entering the transverse transfer device, they initially support the idler tubes together with the receiving plate, and then gradually become supported by the transverse transfer device. Therefore, the impact force on the transverse transfer device is small, the impact force is buffered, the deformation of the equipment is reduced, and damage to the idler tubes is prevented.

[0012] Preferably, a longitudinal transfer device 4 is also provided at the discharge end of the transverse transfer device. The conveying component of the longitudinal transfer device is set at a 90-degree angle to the conveying component of the transverse transfer device and is connected to it, so that their conveying directions are different. The longitudinal transfer device changes the transport direction and conveying mode. On the transverse transfer device, the length direction of the idler tube is perpendicular to the running direction of the transverse transfer device, while on the longitudinal transfer device, the length direction of the idler tube is the same as the running direction of the longitudinal transfer device. That is, it is vertically transferred by the longitudinal transfer device and temporarily stored on it, waiting to be sent to the next process. The width of the conveying component of the longitudinal transfer device can be slightly larger than the diameter of the idler tube to reduce the floor space. To prevent the idler tube from rolling out of the equipment after entering the longitudinal transfer device, a backing plate 19 is provided on the longitudinal transfer device along its running direction. The backing plate 19 is located on the side of the longitudinal transfer device away from the transverse transfer device. The top of the backing plate is inclined outward, that is, towards the side away from the transverse transfer device, to accommodate idler tubes of different diameters. The idler tubes entering the longitudinal transfer device move forward head to tail. With the above structure, after the idler roller tubes are transported to the vicinity of their destination, they are received by the longitudinal transfer device and moved forward. The longitudinal transfer device adjusts the idler roller tubes, which are arranged side-by-side, to a forward-facing arrangement, enabling the idler roller tubes to be positioned. This allows transfer devices such as robotic arms to easily obtain the position of the idler roller tubes and transfer them to the next process. Meanwhile, the transverse transfer device can work simultaneously, maintaining a certain continuity in the production rhythm. The conveying components of the longitudinal transfer device can be transfer rollers, conveyor belts, etc.

[0013] Preferably, the transverse transfer device 2 is a chain conveyor with multiple sets of guide plates 16 on its chain plate. Each set of guide plates includes at least two guide plates 16, the line connecting the two guide plates being perpendicular to the running direction of the chain conveyor, and the spacing between each set of guide plates is equal. The distance between each set of guide plates is adapted to the diameter of the idler tube to be conveyed, providing sufficient space to accommodate the idler tube. The guide plates preferably have the following structure: a chamfer 161 is provided on the upper part of one side surface of the guide plate; bolt through holes 162 are provided on the guide plate for bolts to pass through; the guide plate is fixedly connected to the chain plate of the chain conveyor through the bolt through holes and bolts; the chamfer is inclined relative to the chain plate, tilting from top to bottom from the discharge end to the feed end. The direction of the chamfer of each guide plate is consistent, all facing the receiving idler tube side of the transverse transfer device. With the above structure, the guide plate prevents the idler tubes from rolling on the chain plate, preventing them from tilting against each other and effectively limiting tube offset. There is no stacking of materials. Simultaneously, the chamfered edges can accommodate idler tubes of different diameters, increasing the applicability of the lateral transfer device to the diameter and length of the conveyed idler tubes. Preferably, the guide plate is made of nylon to prevent deformation or damage to the idler tubes due to impact. Ideally, a clearance stop 8 is provided at one end of the buffer pad in the lateral transfer device. The size and spacing of the clearance stop are adapted to the width and spacing of the guide plate, allowing the guide plate to pass through. This allows the buffer pad to cover the turning parts of the chain plate, preventing the chain plate from being impacted by the idler tubes at these points.

[0014] More preferably, a transfer mechanism 3 is provided at the docking point between the longitudinal transfer device and the transverse transfer device, through which the pipe enters the longitudinal transfer device. The transfer mechanism includes a transfer plate, one end of which is fixedly connected to the tail end of the frame of the transverse transfer device, and the other end of which docks with the conveying component of the longitudinal transfer device. The upper surface of the transfer plate slopes downward from the transverse transfer device side to the longitudinal transfer device side. In this way, the idler roller pipe rolls from the transverse transfer device onto the conveying component of the longitudinal transfer device by its own weight, achieving a smooth, unpowered sliding motion of the pipe from the transverse transfer device to the longitudinal transfer device by its own weight.

[0015] Preferably, the longitudinal transfer device includes two parallel chain drive mechanisms, with the chains of the chain drive mechanisms arranged in parallel to form a space for accommodating the idler tube. This structure, with the idler tube supported by two chains, can accommodate different tube diameters and types of idler tubes. To further enhance the supporting force of the chains and expand the adaptability of the longitudinal transfer device, a connecting plate is provided between the two chain plates. Multiple connecting plates secure the two chains, preventing small-diameter idler tubes from falling off.

[0016] The embodiments described above are only used to illustrate the technical principles and features of this utility model. Their purpose is to enable those skilled in the art to understand the content and usage of this utility model and implement it accordingly. The scope of this utility model should not be limited to these embodiments alone. This utility model can have various improvements and variations. All equivalent changes, modifications, or improvements made in accordance with the principles and spirit disclosed in this utility model still fall within the patent scope of this utility model.
