Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and more specifically to a steering conveying device at the end of a fork conveyor. Background Technology

[0002] The shift fork conveyor uses shift forks to push materials and side baffles to limit the movement, so as to achieve directional and efficient material conveying. It is widely used in the field of automated production lines. In order to improve production capacity and conveying efficiency, the equipment generally adopts a high-speed operation mode and connects to the next-level belt conveyor at the end to complete the material turning and cross-line transfer. Existing fork conveyors with side baffles have significant drawbacks in high-speed end-turning and connection operations: when material is pushed to the end of the conveyor by the forks, it is subjected to inertia and velocity impact, directly colliding with the limiting structure at the lower-level conveyor. This can easily lead to rigid rebound, bouncing, lateral displacement, and tilting, causing the material to deviate in position, become disordered, and become unstable when it falls into the lower-level conveyor. This problem is even more pronounced under high-speed conditions, often causing material jamming, accumulation, and even shutdown of the connection section, reducing production line cycle time and yield, and increasing equipment maintenance costs.

[0003] Currently, the industry mostly improves stability by reducing conveying speed, adding simple buffer bars, or adjusting the connection gap. However, slowing down will sacrifice production capacity; the buffer stroke and energy absorption effect of simple buffers are limited, and it is still difficult to eliminate high-speed rebound; gap adjustment is prone to material deviation or jamming, and cannot fundamentally solve the stability problem of high-speed turning connection.

[0004] In view of the problems existing in the prior art, the present invention designs and manufactures a steering conveyor device at the end of a fork conveyor to overcome the above defects. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a steering conveying device at the end of a fork conveyor, which can improve the stability of the steering conveying process and is applicable to high-speed conveying conditions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fork conveyor end-turning conveying device, comprising a fork conveyor, wherein a transfer conveying device is provided at the end of the fork conveyor, and the conveying direction of the transfer conveying device is perpendicular to the conveying direction of the fork conveyor; A limiting plate is provided on one side of the input end of the transfer conveying device. The limiting plate is located on the side of the transfer conveying device away from the shift fork conveyor. A turning conveying mechanism is provided diagonally above the input end of the transfer conveying device. The turning conveying mechanism is located between the end of the shift fork conveyor and the limiting plate. The steering conveying mechanism includes an annular conveying unit and a first driving device for driving the annular conveying unit to rotate. The conveying direction of the annular conveying unit is consistent with the conveying direction of the shift fork conveyor. The annular conveying unit is set in the extended conveying direction of the shift fork conveyor, and the material can be transferred from the shift fork conveyor to the annular conveying unit. The conveying plane of the annular conveying unit is inclined to the horizontal plane, and the material on the annular conveying unit can fall onto the transfer conveying device by gravity.

[0007] Preferably, the annular conveying unit is configured as an annular conveyor belt or multiple O-ring belts.

[0008] Preferably, the transfer conveying device includes a transfer conveying bracket, on which an annular conveying chain plate and a second driving device for driving the conveying chain plate to rotate are provided, and a partition is provided between adjacent conveying chain links on the conveying chain plate.

[0009] Preferably, the steering conveying mechanism includes a steering conveying bracket connected to the transfer conveying bracket, and the annular conveying unit and the first driving device are both disposed on the steering conveying bracket.

[0010] Preferably, the steering conveying bracket includes a steering conveying mounting plate, and the annular conveying unit and the first driving device are respectively disposed on both sides of the steering conveying mounting plate; The position above the steering conveyor mounting plate is higher than the position above the annular conveyor unit.

[0011] Preferably, the steering conveyor mounting plate is equipped with a sensor that can determine whether the material has been transferred to the annular conveyor unit.

[0012] Preferably, the steering conveying bracket is an adjustable bracket, which can adjust the position of the annular conveying unit and the angle between the annular conveying unit and the horizontal plane.

[0013] Preferably, the transfer conveying device has a material batch output channel on one side and a batch material pushing device above the transfer conveying device, which can simultaneously push multiple materials on the transfer conveying device onto the material batch output channel.

[0014] Preferably, the input end of the transfer conveying device is provided with material guide plates on both sides, which can guide the material extending from both sides of the transfer conveying device onto the conveyor chain plate.

[0015] Preferably, each material conveyed by the fork conveyor corresponds to a gap between two adjacent partitions of the transfer conveying device.

[0016] The advantages of this invention are: 1. The annular conveying unit on the turning conveying mechanism of the present invention is inclined, which ensures that the material transferred to the annular conveying unit can slide down to the transfer conveying device below by gravity, thereby realizing the turning and transfer of the material. Moreover, the annular conveying unit maintains the conveying state in the same direction as the fork conveyor, and cooperates with the limiting plate on one side of the transfer conveying device to reduce the rebound of the material caused by the collision of the limiting plate during the reversal, thereby improving the stability of the reversal conveying process.

[0017] 2. In this invention, the annular conveying unit is positioned diagonally above the input end of the transfer conveying device. This structure works in conjunction with the annular conveyor chain plate with partitions to ensure that materials falling from the annular conveying unit can be stably and sequentially transferred to the annular conveyor chain plate with the help of the partitions.

[0020] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, a fork conveyor end-turning conveying device includes a fork conveyor 1. The fork conveyor 1 can output materials to the output end sequentially by means of forks on the conveyor chain. The end of the fork conveyor 1 is provided with a transfer conveying device 2. The conveying direction of the transfer conveying device 2 is perpendicular to the conveying direction of the fork conveyor 1. By transferring to the transfer conveying device 2, the material can be output in batches on the transfer conveying device 2.

[0022] The present invention provides a limiting plate 5 on one side of the input end of the transfer conveying device 2. The limiting plate 5 is located on the side of the transfer conveying device 2 away from the fork conveyor 1. A turning conveying mechanism 3 is provided diagonally above the input end of the transfer conveying device 2. The turning conveying mechanism 3 is located between the end of the fork conveyor 1 and the limiting plate 5. The material on the fork conveyor 1 is transferred to the transfer conveying device 2 by the turning conveying mechanism 3.

[0023] The steering conveying mechanism 3 specifically includes an annular conveying unit 33 and a first driving device 34 for driving the annular conveying unit 33 to rotate. The conveying direction of the annular conveying unit 33 is consistent with the conveying direction of the shift fork conveyor 1. The annular conveying unit 33 is set in the extended conveying direction of the shift fork conveyor 1, and the material can be transferred to the annular conveying unit 33 through the shift fork conveyor 1.

[0024] The conveying plane of the annular conveying unit 33 is inclined to the horizontal plane. Specifically, the inclination direction is downward towards the conveying direction of the transfer conveying device 2. It should be noted that the conveying direction of the annular conveying unit 33 is not inclined. The material on the annular conveying unit 33 can fall from the inclined conveying plane onto the transfer conveying device 2 by gravity.

[0025] The annular conveying unit 33 on the turning conveying mechanism 3 of the present invention is inclined, which ensures that the material transferred to the annular conveying unit 33 can slide down to the transfer conveying device 2 below by gravity, thus realizing the turning and transfer of the material. Moreover, the annular conveying unit 33 maintains the same conveying state as the fork conveyor 1, that is, maintains a certain conveying speed. In cooperation with the limiting plate 5 on one side of the transfer conveying device 2, it reduces the rebound of the material caused by the collision of the material with the limiting plate 5 during the reversal, and improves the stability of the reversal conveying process.

[0026] The annular conveyor unit 33 is configured as an annular conveyor belt or multiple O-ring belts. Since the materials being conveyed are often small bread rolls or instant noodle blocks in packaging bags, multiple O-ring belts are preferred, which can reduce the downward friction when the annular conveyor unit 33 is tilted.

[0027] The transfer conveying device 2 of this invention includes a transfer conveying support, on which a ring-shaped conveyor chain plate and a second driving device for driving the conveyor chain plate to rotate are provided. A partition 6 is provided between adjacent conveyor chain links on the conveyor chain plate. Each material conveyed by the fork conveyor 1 corresponds to a gap between two adjacent partitions 6 in the transfer conveying device 2, and the conveying process is similar to a clip-on conveying mode, improving the stability of the material conveying process. The conveyor chain link mentioned in the above structure is the basic unit constituting the ring-shaped conveyor chain plate. Specifically, the conveyor chain plate is composed of multiple conveyor chain links connected end-to-end to form a certain length.

[0028] The circular conveying unit 33 is located diagonally above the input end of the transfer conveying device 2. This structure cooperates with the circular conveying chain plate with partition 6 to ensure that the materials falling from the circular conveying unit 33 can be stably transferred to the circular conveying chain plate in sequence with the help of the partition 6.

[0029] The present invention's steering conveying mechanism 3 includes a steering conveying bracket 31, which is connected to a transfer conveying bracket. The annular conveying unit 33 and the first driving device 34 are both disposed on the steering conveying bracket 31. The steering conveying bracket 31 specifically includes a steering conveying mounting plate 32. The annular conveying unit 33 and the first driving device 34 are respectively disposed on both sides of the steering conveying mounting plate 32. Furthermore, the upper position of the steering conveying mounting plate 32 is higher than the upper position of the annular conveying unit 33, which further ensures that the material can only fall obliquely from the annular conveying unit 33 onto the transfer conveying device 2.

[0030] A sensor is preferably provided on the steering conveyor mounting plate 32. The sensor can determine whether the material has been transferred to the ring conveyor unit 33 so as to cooperate with the transfer conveyor device 2 for stable conveying. In particular, it can cooperate with the conveyor chain plate with partitions 6 to ensure that the material can enter the space between the two partitions 6 in a stable manner.

[0031] The steering conveyor bracket 31 is preferably configured as an adjustable bracket, which can adjust the position of the annular conveyor unit 33 and the angle between the annular conveyor unit 33 and the horizontal plane.

[0032] The transfer conveying device 2 of this invention has a material batch output channel 4 on one side and a batch material pushing device above it. The batch material pushing device can simultaneously push multiple materials on the transfer conveying device 2 onto the material batch output channel 4. At the same time, a non-conforming material rejection channel 8 can be set on the other side of the transfer conveying device 2 to cooperate with the non-conforming material rejection pushing device to reject non-conforming materials.

[0033] Material guide plates 7 are preferably provided on both sides of the input end of the transfer conveying device 2. The material guide plates 7 can guide the material extending from both sides of the transfer conveying device 2 onto the conveyor chain plate.

[0034] The actual working process of this invention: Materials are sequentially conveyed to the output end of the fork conveyor 1. Since the materials are conveyed at high speed to the annular conveying unit 33 of the turning conveying mechanism 3, when they touch the limit plate 5, the same-direction conveying speed of the annular conveying unit 33 reduces the rebound caused by the material hitting the limit plate 5 during the reversal, so that the material can be temporarily held on the annular conveying unit 33. However, since the annular conveying unit 33 is tilted, the material will slide down to the transfer conveying device 2 below by gravity, thereby realizing the turning and transfer of the material. This structure is particularly suitable for continuous turning conveying of the high-speed fork conveyor 1.

[0035] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of the invention. Furthermore, it should be understood that after reading the technical description of this invention, those skilled in the art can make various alterations, modifications, and / or variations to the invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
