Description

Technical Field

[0001] This invention relates to the field of roller sorting technology, and in particular to a roller sorting machine and its working method. Background Technology

[0002] After the bearing rollers are processed, a sorting device is usually needed to sort the rollers so that bearing rollers of the same length can be collected together.

[0003] Existing automatic roller sorting machines (such as CN102962210A) use a circular tray to transport rollers onto a conveyor belt. The conveyor belt moves the rollers for detection, and pushers push the rollers to designated positions. Because the circular tray has semi-circular slots, the rollers need to be manually placed into the corresponding slots, which is time-consuming, labor-intensive, and labor-intensive. Moreover, most of them have several opposing side plates on one side of the conveyor belt. During the pushing process, the pushers can easily push the rollers into the space between two adjacent side plates in the designated storage space, causing roller sorting errors. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a roller sorting machine and its working method, which solves the problems of high labor intensity and poor sorting accuracy of existing automatic roller sorting machines.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0006] In a first aspect, the present invention provides a roller sorting machine, comprising: mounted on a worktable.

[0007] The feeding mechanism consists of a support platform and baffles that are relatively fixedly installed on the support platform, with a conveyor belt between the two baffles;

[0008] The guiding mechanism is located on one side of the feeding mechanism and perpendicular to it. It consists of two rotating shafts that rotate relative to each other. One end is equipped with a conveyor belt and the other end is equipped with a first push rod.

[0009] The inspection mechanism, located at the discharge end of the guiding mechanism, is used to inspect the roller size;

[0010] The conveyor belt has several second push rods spaced apart along its length on one side, and a material trough corresponding to each second push rod on the other side.

[0011] As a further implementation, the direction of movement of the conveyor belt is parallel to the axis of the guiding mechanism.

[0012] As a further implementation, the conveyor belt has a concave structure in the middle.

[0013] As a further implementation, the spacing between the baffles is not less than the length of the longest roller among the rollers to be tested.

[0014] As a further implementation, the guiding mechanism is mounted on the workbench via a support base. The guiding mechanism is higher than the conveyor belt and its centerline does not coincide with the centerline of the conveyor belt. The guiding mechanism is adjacent to the conveyor belt via an inclined guide plate.

[0015] As a further implementation, the guiding mechanism is mounted on the workbench, with the guiding mechanism at the same height as the conveyor belt and the center line of the guiding mechanism coinciding with the center line of the conveyor belt.

[0016] As a further implementation, an inclined feeding plate is provided on one side of the conveyor belt. The feeding plate is fixedly installed on the workbench, and the top of the feeding plate is at the same height as the conveyor belt. Several side plates are fixedly installed on the feeding plate at intervals along the length of the conveyor belt, and a material trough is formed between two adjacent side plates.

[0017] As a further implementation, one end of the side plate extends above the conveyor belt, and the portion of the side plate above the conveyor belt has through holes that allow rollers to pass through.

[0018] As a further implementation, the workbench is equipped with a position sensor for detecting the position of the roller, and the position sensor, the first push rod, the second push rod, and the detection mechanism are all connected to the control mechanism set on the workbench.

[0019] Secondly, the present invention provides a method for operating a roller sorting machine, as detailed below:

[0020] The rollers to be sorted are manually placed onto the feeding mechanism, so that the axis of the rollers is perpendicular to the center line of the feeding mechanism;

[0021] The rollers on the feeding mechanism are automatically fed onto the guiding mechanism;

[0022] Under the action of the rotating shaft, the axial direction of the roller is made parallel to the axial direction of the rotating shaft. The first push rod works to push the roller on the guiding mechanism to the middle recess of the conveyor belt and the detection mechanism detects the roller size.

[0023] The roller moves along the conveyor belt and passes through the side plate. When the position sensor detects that the roller has moved to the designated trough, the second push rod pushes the roller into the designated trough.

[0024] The beneficial effects of the present invention are as follows:

[0025] (1) The feeding mechanism of the present invention no longer sets a corresponding slot for the roller, which greatly reduces the difficulty of placing the roller. At the same time, it works together with the guide mechanism. Under the action of the guide mechanism's rotating shaft, it ensures that the roller is pushed onto the conveyor belt in the axial direction and position, so that the roller can be pushed off the conveyor belt by the second push rod. The whole process does not require much human intervention, has high accuracy, and greatly reduces labor intensity.

[0026] (2) The central recess of the conveyor belt of the present invention can effectively limit the position of the roller on the conveyor belt, ensuring that the roller can accurately pass through the through hole on the side plate and avoid the roller being blocked by the side plate.

[0027] (3) Under the action of the guiding mechanism, the axial direction of the roller is the same as the direction of movement of the conveyor belt, so that the roller will not rotate around the axis in place during the movement of the conveyor belt, which greatly improves the conveying efficiency of the roller and avoids the roller falling vertically onto the conveyor belt and avoids the roller being blocked by the side plate.

[0028] (4) The side plate of the present invention extends above the conveyor belt, which can effectively limit the rollers on the conveyor belt and prevent the rollers from rolling into the adjacent trough during the second pusher push, thus greatly ensuring the sorting accuracy of the rollers.

Detailed Implementation

[0034] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0035] As described in the background section, existing automatic roller sorting machines use a circular tray to transport rollers onto a conveyor belt. The conveyor belt then moves the rollers for detection, and pushers push the rollers to designated positions. Because the circular tray has semi-circular slots, manual placement of the rollers into the corresponding slots is required, which is time-consuming, labor-intensive, and labor-intensive. Furthermore, several opposing side plates are often set on one side of the conveyor belt, and the pushers can easily push the rollers into the space between two adjacent side plates in the designated storage space, causing roller sorting errors. To solve the above technical problems, this invention proposes a roller sorting machine and its working method.

[0036] Example 1

[0037] In a typical embodiment of the present invention, such as Figures 1-2 As shown, a roller sorting machine is proposed, including a feeding mechanism 2, a guiding mechanism 3, a detection mechanism 4, a conveyor belt 5, a push rod, and a material trough 9 installed on a worktable 1.

[0038] The feeding mechanism 2 is located on one side of the guiding mechanism 3 and is used to feed the rollers onto the guiding mechanism 3. The guiding mechanism 3 guides the rollers so that the axial direction of the rollers is the same as the moving direction of the conveyor belt 5.

[0039] The guide mechanism 3 has a first push rod 6 at one end and a conveyor belt 5 at the other end. The first push rod 6 is used to push the rollers that have been guided on the guide mechanism 3 onto the conveyor belt 5 for conveying.

[0040] A number of second push rods 7 are spaced apart along the length of one side of the conveyor belt 5, and a number of material troughs 9 are provided along the length of the other side. The number of material troughs 9 is the same as the number of second push rods 7 and they correspond one-to-one, so as to accommodate the rollers pushed down from the conveyor belt 5 by the second push rods 7.

[0041] The feeding mechanism 2, the guiding mechanism 3, and the detection mechanism 4 are all installed on the support base 11, which is fixedly installed on the workbench 1. Thus, the height of the feeding mechanism 2, the guiding mechanism 3, and the detection mechanism 4 is higher than that of the conveyor belt 5 by using the support base 11.

[0042] It is understood that in other embodiments, the feeding mechanism 2, the guiding mechanism 3, and the detection mechanism 4 may not be installed on the support base 11, and the specific selection can be made according to actual needs.

[0043] The feeding mechanism 2 is perpendicular to the guiding mechanism 3. The feeding mechanism 2 consists of a support platform 21 and a baffle 22. The support platform 21 is fixedly installed on the support base 11. There are two baffles 22, which are fixedly installed on the support platform 21. There is a space between the two baffles 22 for accommodating the roller.

[0044] It should be noted that the distance between the two baffles 22 should not be less than the length of the longest roller among the rollers to be tested, so as to ensure that all rollers can be placed between the two baffles 22. When placing the rollers, the axial direction of the rollers should be perpendicular to the baffles 22.

[0045] In this embodiment, a conveyor belt is provided between the two baffles 22 to drive the rollers onto the guiding mechanism 3.

[0046] It is understood that in other embodiments, the conveying device can be omitted, and the support platform 21 can be set to tilt towards the guide mechanism 3. In this case, an automatic lifting door structure that can be opened and closed up and down needs to be set between the two baffles 22 near the guide mechanism 3 to control the start and stop of the roller falling onto the guide mechanism 3. The specific feeding method of the feeding mechanism can be selected according to actual needs, and no further restrictions are imposed here.

[0047] The guiding mechanism 3 consists of two opposing rotating shafts. Both rotating shafts rotate around their axes and rotate relative to each other, thereby driving the roller to rotate around its own axis. This makes the axial direction of the roller parallel to the axial direction of the rotating shaft, thus guiding the roller.

[0048] The first push rod 6 can use its telescopic rod to push the rollers on the two rotating shafts, thereby pushing the rollers onto the conveyor belt 5.

[0049] The setting of feeding mechanism 2 and guiding mechanism 3 eliminates the need for manual installation of rollers into the corresponding slots on the material tray. Instead, the rollers can be placed on feeding mechanism 2 by hand, which greatly reduces labor intensity.

[0050] The detection mechanism 4 is fixedly installed on the support base 11 and located on both sides of the end of the guide mechanism 3 away from the first push rod 6. It is mainly used to detect the rollers on the guide mechanism 3. The detection mechanism 4 consists of two laser emitters and laser receivers arranged opposite to each other to detect the length and diameter of the rollers.

[0051] It is understandable that the detection mechanism 4 can also be configured as other types of sensors for detecting the length and diameter of the roller. The specific configuration can be determined according to actual needs, and no further restrictions are imposed here.

[0052] When the guiding mechanism 3 is installed on the support base 11, the center line of the conveyor belt 5 does not coincide with the center line of the guiding mechanism 3. The discharge end of the guiding mechanism 3 is connected to the conveyor belt 5 through the inclined guide plate 10. The guide plate 10 is fixedly installed on the support base 11. The rollers on the guiding mechanism 3 can slide down along the guide plate 10 onto the conveyor belt 5 to prevent the rollers from falling and being damaged or falling off the conveyor belt 5.

[0053] Due to the setting of the guide plate 10, the roller can slide onto the conveyor belt 5, so that the axial direction of the roller is the same as the moving direction of the conveyor belt 5, thereby preventing the roller from rotating around the axis under the drive of the conveyor belt 5.

[0054] To further restrict the position of the rollers, the conveyor belt 5 has a concave structure in the middle, so that the rollers can keep their axis in the same direction of movement as the conveyor belt 5 when they slide onto the conveyor belt 5, and accurately slide onto the middle position of the conveyor belt 5.

[0055] In other embodiments, when the guide mechanism 3 is not set on the support base 11, the center line of the conveyor belt 5 coincides with the center line of the guide mechanism 3. At this time, the guide plate 10 is not set, the conveyor belt 5 is at the same height as the guide mechanism 3, and the first push rod 6 directly pushes the roller onto the conveyor belt 5. The conveyor belt 5 also has a structure with a concave center.

[0056] It is understandable that the specific positional relationship between the conveyor belt 5 and the guiding mechanism 3 can be designed according to actual needs, and no further restrictions will be imposed here.

[0057] The second push rod 7 and the material trough 9 are arranged opposite each other on both sides of the conveyor belt 5. The material trough 9 is formed by the cooperation of the oppositely arranged side plates 8. Specifically, one side of the conveyor belt 5 is provided with an inclined feeding plate. The feeding plate is fixedly installed on the workbench 1, and the top of the feeding plate is at the same height as the conveyor belt 5. Several side plates 8 are fixedly installed on the feeding plate at intervals along the length of the conveyor belt 5, and the material trough 9 is formed between two adjacent side plates 8.

[0058] One end of the side plate 8 extends above the conveyor belt 5. The portion of the side plate 8 above the conveyor belt 5 has a through hole that allows the roller to pass through. The center line of the through hole coincides with the center line of the middle groove of the conveyor belt 5. Thus, when the second push rod 7 pushes the roller, under the restriction of the side plate 8, the roller can only be pushed into the corresponding trough 9 and will not roll into the adjacent trough 9 due to offset, which effectively improves the sorting accuracy.

[0059] It should be noted that the depth of the groove in the middle of the conveyor belt 5 should avoid interfering with the operation of the second push rod 7. The specific depth needs to be determined according to actual needs.

[0060] The workbench 1 is also equipped with a position sensor, which can detect the movement position of the roller. When rollers of different sizes move to the corresponding material trough 9 under the action of the conveyor belt 5, the second push rod 7 at the corresponding position will push the roller off the conveyor belt 5.

[0061] The position sensor can also be set on the side panel 8. The specific setting position can be determined according to actual needs, and there are no restrictions here.

[0062] Understandably, the workbench 1 is also equipped with a control mechanism to receive detection information from the detection mechanism and position sensor and to control the operation of the first push rod 6, the second push rod 7, and the automatic lifting door (if present) on the feeding mechanism 2.

[0063] Example 2

[0064] In another typical embodiment of the present invention, a working method for a roller sorting machine is proposed, as follows:

[0065] The rollers to be sorted are manually placed between the two baffles 22 of the feeding mechanism 2, so that the axis of the rollers is perpendicular to the center line of the feeding mechanism 2;

[0066] The rollers on the feeding mechanism 2 are automatically fed onto the guiding mechanism 3 under the action of the conveyor belt / gravity;

[0067] The rollers on the guiding mechanism 3 are guided by the rotating shaft, so that the axial direction of the rollers is parallel to the axial direction of the rotating shaft. The first push rod 6 pushes the rollers on the guiding mechanism 3 to the middle recess of the conveyor belt 5.

[0068] During the process of the roller being pushed onto the conveyor belt 5, the detection mechanism 4 detects the size of the roller and transmits the detection data to the control mechanism. The control mechanism determines the corresponding trough 9 based on the size of the roller.

[0069] The roller moves under the drive of the conveyor belt 5, and during the movement, the roller passes through the through hole on the side plate 8. When the position sensor detects that the roller has moved to the designated trough 9, the second push rod 7 works to push the roller into the corresponding trough 9.

[0070] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
