Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for tapered roller production, and more specifically, to a tapered roller feeding device. Background Technology

[0002] The company is currently implementing automated visual inspection equipment to replace manual inspection of the end face appearance of tapered rollers. The application of automated visual inspection equipment requires tapered rollers to be fed in with the small end down and the large end up. The company's existing roller hopper output equipment only has the function of outputting tapered roller products one by one downwards, but the orientation of the output tapered rollers cannot be determined (either the small end down or the large end down is possible). This cannot meet the feeding requirements of the automated visual inspection equipment. The company is considering designing a tapered roller feeding device that can screen out the correct orientation to meet production needs, and this case arises from this. Utility Model Content

[0003] The purpose of this invention is to address the needs of the prior art by providing a tapered roller feeding device. The feeding conveyor belt of this invention uses a carrier plate to receive the tapered rollers. The carrier plate has an autonomous screening function; tapered rollers with the smaller end facing down automatically fall into position, while those with the larger end facing down slide down for recycling. All tapered rollers fed by this invention have their smaller ends facing down, which can meet the production needs of subsequent equipment. This invention has the advantage of a high degree of automation and can meet the needs of enterprises upgrading to automated production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tapered roller feeding device includes a feeding conveyor belt and a screening and recycling mechanism. A loading station is provided at the beginning of the conveying direction of the feeding conveyor belt, and a feeding station is provided at the end of the conveying direction of the feeding conveyor belt. The feeding conveyor belt is a chain plate type conveyor belt. The feeding conveyor belt includes plates arranged in an array. Each plate includes a carrier plate capable of screening the material facing the tapered rollers. The screening and recycling mechanism is installed on the side of the loading station, and a feeding mechanism is installed on the feeding station.

[0006] Furthermore, the surface of the material carrier plate is set as an inclined slope, and a material drop hole is opened in the center of the surface of the material carrier plate. The material drop hole is a tapered hole, and the diameter of the opening of the material drop hole is adapted to the tapered roller to be inserted with the small end face.

[0007] Furthermore, the screening and recycling mechanism includes a receiving trough and a recycling box. The receiving trough is installed at an angle, with its high point extending towards the low point of the slope of the material carrier plate, and its low point extending into the inside of the recycling box.

[0008] Furthermore, the plate also includes a partition plate, which is arranged alternately with the material carrier plate. The partition plate has the same slope as the material carrier plate, and the surface of the partition plate is smooth.

[0009] Furthermore, sensor markers are affixed and installed at the highest points of the slope of the material carrier plate.

[0010] Furthermore, the feeding mechanism includes overhead tracks and a trolley. Two overhead tracks are symmetrically installed on both sides of the width direction of the feeding conveyor belt. The trolley is movably installed on the two overhead tracks. A lifting device is installed on the trolley. A mechanical gripper is connected to the end of the lifting shaft of the lifting device. The travel of the trolley extends beyond the outer end of the conveying direction of the feeding conveyor belt.

[0011] Furthermore, the feeding station is equipped with an incoming material sensing element, which includes a sensor. The sensor is installed on the side of the feeding conveyor belt, and a contact rod is connected to the sensor. The contact rod laterally blocks the movement path of the tapered roller. The installation height of the contact rod is higher than the highest point of the carrier plate, but lower than the highest point of the tapered roller loaded on the carrier plate.

[0012] Furthermore, a limited high-definition surface element is also installed in the conveying direction of the feeding conveyor belt. The limited high-definition surface element is installed in the rear channel of the loading station, but is within the recycling range of the screening and recycling mechanism.

[0013] Furthermore, the height limiting surface element includes a column and a height limiting rod. The two columns are erected vertically and symmetrically installed on both sides of the width direction of the feeding conveyor belt. The height limiting rod is installed horizontally and its two ends are fixedly connected to the two columns respectively. The installation height of the height limiting rod is higher than the highest point of the tapered roller that is normally positioned, and the installation height of the height limiting rod is lower than the highest point of the tapered roller that is abnormally positioned and stuck on the loading plate.

[0014] The beneficial effects of this utility model are:

[0015] This utility model's feeding conveyor belt uses a carrier plate to receive tapered rollers. Utilizing the different diameters of the large and small ends of the tapered rollers, the carrier plate can screen and separate the orientation of the received tapered rollers. Tapered rollers with the small end facing down automatically fall into position, while those with the large end facing down slide down for recycling. In this way, the tapered rollers fed by this utility model are all with the small end facing down, which can meet the production needs of subsequent equipment. This utility model automatically completes all stages of feeding, screening, recycling, and conveying, which can meet the needs of enterprises to upgrade to automated production.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5The conical roller feeding device shown includes a feeding conveyor belt 1 and a screening and recycling mechanism 2. This invention features a loading station 11 at the starting end of the conveying direction of the feeding conveyor belt 1. The loading station 11 is used to load conical roller products. This invention is used with the company's existing roller hopper (existing equipment, not shown in the figure). The roller hopper can output conical roller products vertically one by one. However, the output conical roller products may have two orientations: small end down or large end down. The company requires an automated visual inspection device (not shown in the figure) that only accepts conical roller products with the small end down. Therefore, the feeding device of this invention needs to be designed with the function of screening the conical roller orientation. The new design adopts a chain plate type conveyor belt for the feeding conveyor belt 1. The feeding conveyor belt 1 includes plates 13 arranged in a row. After the feeding conveyor belt 1 starts, it can circulate the plates 13. The plates 13 include a carrier plate 131, which is used to receive tapered rollers output from the roller hopper. A drop hole 134 is opened in the center of the surface of the carrier plate 131. The drop hole 134 is a tapered hole. The diameter of the drop hole 134 is adapted to the tapered rollers to be inserted with the small end face. That is to say, when the carrier plate 131 enters the loading station 11, a single tapered roller output from the roller hopper falls. If the tapered roller is facing downwards with the small end face down, then the tapered roller is facing correctly and can be directly inserted into the drop hole 134. The diameter of the orifice 134 is smaller than the diameter of the large end face of the tapered roller. If the large end face of the tapered roller is facing down, the falling tapered roller cannot be partially inserted into the discharge hole 134. This invention also designs the surface of the carrier plate 131 as an inclined slope 133. The slope 133 has a gradient and a smooth surface. If the tapered roller cannot be inserted into the discharge hole 134, it can only slide down the slope 133. Therefore, the incorrectly oriented tapered rollers will be screened out from the feeding conveyor belt 1, ensuring that the tapered rollers fed by the feeding conveyor belt 1 are all correctly oriented with their small end facing down. This invention installs the screening and recycling mechanism 2 on the side of the loading station 11. The screening and recycling mechanism 2 is used to collect the tapered rollers that have fallen due to incorrect orientation. The conical rollers are screened and recycled. The recycling mechanism 2 includes a receiving trough 21 and a recycling box 22. The receiving trough 21 is installed at an angle. The high point of the receiving trough 21 extends towards the low point of the slope 133 of the carrying plate 131. The low point of the receiving trough 21 extends into the inside of the recycling box 22. Conical rollers that fall incorrectly onto the slope 133 of the carrying plate 131 are collected in the recycling box 22 through the receiving trough 21. When the number of conical rollers in the recycling box 22 becomes large, they are still transported and replenished to the roller hopper. This utility model has a feeding station 12 at the end of the conveying direction of the feeding conveyor belt 1. The feeding station 12 is equipped with a corresponding feeding machine 3. The feeding machine 3 grabs the conical rollers on the feeding station 12 and feeds them to the automated vision inspection equipment.

[0024] like Figure 1As shown, the plate 13 of this utility model also includes a partition plate 132. The partition plate 132 and the material carrier plate 131 are arranged alternately to increase the distance between adjacent material carrier plates 131. The partition plate 132 is provided with the same slope 133 as the material carrier plate 131. The slope and orientation of the slope 133 are the same, and the surface of the partition plate 132 is smooth, so that even if the conical roller is oriented incorrectly, it can still slide smoothly off the partition plate 132.

[0025] like Figures 1-3 As shown, a sensor mark 135 is affixed and installed at the high point of the ramp 133 of the loading plate 131. A corresponding inductive sensor can be installed on the side wall of the output pipe of the roller hopper. This sensor is used to detect the sensor mark 135. The output pipe of the roller hopper is located directly above the loading station 11. After the loading plate 131 enters the loading station 11, the sensor on the output pipe of the roller hopper detects the sensor mark 135 and sends out a tapered roller product to drop with this signal.

[0026] like Figure 1 As shown, the feeding mechanism 3 includes an overhead track 31 and a trolley 32. The two overhead tracks 31 are symmetrically installed on both sides of the feeding conveyor belt 1 in the width direction. The trolley 32 is movably mounted on the two overhead tracks 31, which elevate the trolley 32, allowing it to move above the feeding station 12. Figure 5 As shown, a lifting device 33 is installed on the trolley 32. The lifting device 33 is an existing device, and many models are available on the market. The structure will not be described in detail here. The lifting device 33 includes a lifting shaft that can move up and down. A mechanical gripper 34 is connected and installed at the end of the lifting shaft of the lifting device 33. The lifting device 33 drives the mechanical gripper 34 to move up and down. The mechanical gripper 34 is used to grab or release the tapered rollers. The mechanical gripper 34 is also a conventional device on the market. The structure will not be described in detail here. The overhead track 31 of this utility model is equipped with a travel limiter 311, which restricts the travel of the trolley 32. The travel of the trolley 32 needs to extend beyond the outer end of the conveying direction of the feeding conveyor belt 1. This is necessary to meet the requirements of the automated visual inspection equipment for feeding. The trolley 32 can also run directly above the feeding station 12 to fulfill the function of grabbing the tapered roller products.

[0027] In the use of this utility model, since the orientation of the output rollers in the roller hopper is uncertain, only the correctly oriented tapered rollers can remain on the loading plate 131, while the incorrectly oriented tapered rollers will be screened off by the loading plate 131. Therefore, it cannot be guaranteed that each loading plate 131 will be loaded with tapered rollers. To ensure that tapered rollers are available at the feeding station 12, such as... Figure 1 and Figure 4As shown, the present invention provides a material feeding station 12 equipped with an incoming material sensing element 4. The incoming material sensing element 4 includes a sensor 41, which is installed on the side of the feeding conveyor belt 1. The sensor 41 adopts a contact trigger mode and is linked with the feeding conveyor belt 1. The sensor 41 is connected to a contact rod 42, which achieves the purpose of contact detection. The contact rod 42 laterally blocks the movement path of the tapered roller. The installation height of the contact rod 42 is higher than the highest point of the carrier plate 131, but lower than the highest point of the tapered roller loaded on the carrier plate 131. At the specified height, if the carrier plate 131 is unloaded, it will pass directly through the feeding station 12 at a fixed frequency (the fixed frequency refers to the frequency at which the feeding conveyor belt 1 carrying the carrier plate 131 stays at the loading station 11 for 2-3 seconds to meet the loading requirements). If the carrier plate 131 is loaded with tapered rollers, the tapered rollers can touch the contact rod 42, and the sensor 41 will send a control signal to control the feeding conveyor belt 1 to stop, so as to allow time for the feeding machine 3 to grab and feed the material. The stopping time of the feeding conveyor belt 1 shall not exceed 30 seconds (the feeding operation is generally completed within 30 seconds).

[0028] Because the surface of the loading plate 131 is an inclined slope 133, under normal circumstances, the tapered rollers facing the wrong direction (large end down) will automatically slide off. However, occasionally some may remain stuck on the plate surface. Therefore, such as Figures 1-3 As shown, this utility model also installs a height-limiting surface element 5 in the conveying direction of the feeding conveyor belt 1. The height-limiting surface element 5 is installed after the loading station 11, but within the recovery range of the screening and recovery mechanism 2. The height-limiting surface element 5 plays the role of sweeping off the retained conical rollers, and the swept-off retained conical rollers are also recovered by the screening and recovery mechanism 2. The height-limiting surface element 5 includes a column 51 and a height-limiting rod 52. The two columns 51 are vertically and symmetrically installed on both sides of the width direction of the feeding conveyor belt 1, and the height-limiting rod 52 is horizontally installed and fixed at both ends. Connected to two columns 51, the tapered rollers positioned in the correct orientation have their lower ends inserted into the material drop holes 134. Therefore, the height of the tapered rollers positioned in the correct orientation is lower than that of the tapered rollers positioned in the incorrect orientation. This invention utilizes this characteristic to design the installation height of the height limiting rod 52. The installation height of the height limiting rod 52 is designed to be higher than the highest point of the tapered rollers positioned in the correct orientation, and lower than the highest point of the tapered rollers positioned in the incorrect orientation and stuck on the loading plate 131. Figure 2 As shown, the tapered rollers that are positioned in the normal orientation can pass smoothly through the height limit bar 52, while the tapered rollers that are stuck on the material plate 131 in an abnormal orientation will be blocked by the height limit bar 52 and will naturally slide down and be recycled during the movement, thus solving the problem of stuck rollers on the plate.

[0029] This invention has the advantage of a high degree of automation, with automatic completion of each stage of feeding, screening, recycling, and delivery. This invention has good practical effects and can meet the needs of enterprises to upgrade to automated production.
