Description

Technical Field

[0001] The present invention relates to the technical field of bearing processing, and in particular to a roller discharging device of a circumferential surface grinder and a working method thereof. Background Art

[0002] During the roller processing, a mold is required to process the circumferential surface. After the processing is completed, the cylinder is used to push it to the conveying mechanism for discharge and transportation.

[0003] In the existing roller discharging device, its conveying mechanism is divided into two types. One is a slide structure, which is set obliquely downward. The rollers after processing automatically slide downward by gravity and are guided to the designated position. During the sliding process, it is very easy for the rollers to collide with each other, causing surface damage; the other is a conveyor belt structure, which transports the processed rollers to the designated position through the conveyor belt. During the conveying process, when the axis of the roller is perpendicular to the moving direction of the conveyor belt, the roller will rotate around the axis, and the movement and state of the roller cannot be controlled, which can easily lead to collisions between the rollers on the conveyor belt. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a roller discharge device and working method for a circular surface grinder. The conveying mechanism is set obliquely upward and tilted to one side, so that the moving speed of the roller during the upward transportation process will not be too fast due to the influence of gravity, and the roller is avoided from rotating around the axis in situ on the conveyor belt, thereby solving the problem that the existing roller discharge and conveying is prone to collision damage.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] In the first aspect, the present invention provides a roller discharge device for a circular surface grinder, comprising a guide mechanism and a conveying mechanism, wherein one end of the guide mechanism is connected to the discharge port of the circular surface grinder, and the other end is located above the conveying mechanism, wherein the conveying mechanism consists of a U-shaped groove and a conveyor belt installed in the U-shaped groove, and the conveying mechanism is arranged obliquely upward as a whole and tilted toward the direction close to the guide mechanism, and the feed end of the conveyor belt is lower than its discharge end.

[0007] As a further implementation, the U-shaped trough is composed of a first bottom plate and baffles fixedly mounted on both sides of the first bottom plate, the length of the baffles is the same as the length of the conveyor belt, and the width of the baffles is greater than the conveyor belt.

[0008] As a further implementation, both ends of the conveying mechanism are supported by first brackets, each first bracket includes two retractable support rods, and each support rod is hinged to a baffle.

[0009] As a further implementation method, the guide mechanism is supported by a retractable second bracket, and the guide mechanism consists of a first guide part, a third guide part and a second guide part connected in sequence. The first guide part is higher than the second guide part, and the first guide part is connected to the discharge port of the circumferential surface grinder. The second guide part is located above the conveyor belt, and the bottom plates of the first guide part, the second guide part and the third guide part are all arranged obliquely downward and inclined toward the same side.

[0010] As a further implementation, the axial direction of the first guide portion is perpendicular to the axial direction of the conveying mechanism, the axial direction of the second guide portion is parallel to the axial direction of the conveyor belt, and the third guide portion is an arc-shaped transition structure.

[0011] As a further implementation, the first guide portion is composed of a second bottom plate and first side plates fixed on both sides thereof, and the second bottom plate is arranged obliquely downward toward the direction close to the conveying mechanism and inclined toward the moving direction of the conveyor belt.

[0012] As a further implementation, the second guide portion is composed of a third bottom plate and second side plates fixed on both sides thereof, and the third bottom plate is arranged obliquely downward and inclined toward the direction in which the conveyor belt is inclined.

[0013] As a further implementation, the third guide portion is composed of a fourth bottom plate and third side plates fixed on both sides thereof, the fourth bottom plate has a slope toward the second guide portion and is inclined toward the direction in which the second bottom plate and the third bottom plate are inclined.

[0014] As a further implementation, a plurality of anti-skid grooves perpendicular to the conveying direction of the conveyor belt are provided on the surface of the conveyor belt, and the anti-skid grooves are arranged at intervals along the length direction of the conveyor belt.

[0015] In a second aspect, the present invention provides a working method of a roller discharge device of a circumferential surface grinder, which is as follows:

[0016] The telescopic cylinder on the circumferential surface grinding machine pushes the roller after machining into the first guide part;

[0017] The roller is guided by the first guide part, the third guide part and the second guide part in sequence, and then falls onto the conveyor belt for transportation in an axial direction that is the same as the moving direction of the conveyor belt.

[0018] The beneficial effects of the present invention are as follows:

[0019] (1) The conveyor belt of the present invention is arranged obliquely upward so that the moving speed of the rollers during the upward transportation process will not be too fast due to the influence of gravity, effectively avoiding the problem of collision damage between rollers due to uncontrolled moving speed; and the conveyor belt is inclined to one side, so that the rollers falling on the conveyor belt can slide along the inclined conveyor belt, and finally the axial direction of the roller is the same as the moving direction of the conveyor belt. The rollers can move upward under the drive of the conveyor belt without rotating around the axis, effectively improving the conveying effectiveness of the conveyor belt arranged obliquely on the rollers, simplifying the structure, facilitating control, and reducing costs.

[0020] (2) The bottom plates of the first guide portion, the second guide portion and the third guide portion of the present invention are all arranged obliquely downward and inclined toward the same side, which limits the inclination direction of the first guide portion, the second guide portion and the third guide portion, so that the roller can adjust its posture in advance before rolling onto the conveyor belt. The roller finally slides onto the conveyor belt with the axial direction being the same as the conveying direction of the conveyor belt, ensuring that the roller can move with the conveyor belt in time after falling onto the conveyor belt, and will not rotate around the axis in situ, thereby greatly improving the conveying efficiency of the conveyor belt and avoiding the occurrence of roller aggregation and collision.

[0021] (3) The anti-skid grooves on the conveyor belt of the present invention effectively increase the friction between the conveyor belt surface and the rollers, thereby improving the follow-up performance of the rollers and the conveyor belt.

[0022] (4) The guide mechanism and the conveying mechanism of the present invention are both supported by retractable brackets, and their heights can be adjusted according to needs. The inclination angle of the conveying mechanism is adjustable and can adapt to rollers of different sizes. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] It should be noted that the following detailed description is illustrative and is intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meaning as commonly understood by those skilled in the art to which the present invention belongs.

[0031] As introduced in the background technology, in the existing roller discharging device, its conveying mechanism is divided into two types. One is a slide structure, which is arranged obliquely downward. The rollers after processing automatically slide downward by gravity and are guided to the designated position. During the sliding process, it is very easy for the rollers to collide with each other, causing surface damage; the other is a conveyor belt structure, which transports the processed rollers to the designated position through the conveyor belt. During the conveying process, when the axis of the roller is perpendicular to the moving direction of the conveyor belt, the roller will rotate around the axis, and the movement and state of the roller cannot be controlled, which can easily lead to collisions between the rollers on the conveyor belt. In order to solve the above technical problems, the present invention proposes a roller discharging device and a working method for a circular surface grinder.

[0032] Example 1

[0033] In a typical embodiment of the present invention, Figure 1-Figure 4 As shown, a roller discharge device for a circular surface grinder is proposed, comprising a guide mechanism 1 and a conveying mechanism 2, wherein one end of the guide mechanism 1 is connected to the discharge port of the circular surface grinder, and the other end is located above the conveying mechanism 2. The roller 5 processed on the circular surface grinder falls onto the conveying mechanism 2 for transportation through the guide mechanism 1.

[0034] The conveying mechanism 2 is composed of a baffle 21, a conveyor belt 22 and a first bottom plate, wherein two baffles 21 are provided, and the two baffles 21 are relatively fixedly arranged on both sides of the first bottom plate. The two baffles 21 and the first bottom plate are combined to form a U-shaped trough structure with a U-shaped cross section;

[0035] The conveyor belt 22 is installed between the two baffles 21. The length of the conveyor belt 22 is the same as that of the baffles 21, so that the baffles 21 on both sides can be used to block the rollers 5 on the conveyor belt 22 to prevent the rollers 5 from sliding out of the conveyor belt 22.

[0036] The conveying mechanism 2 is arranged as a whole obliquely upward and inclined obliquely downward toward the direction close to the guide mechanism 1. Specifically, the height of one end of the conveyor belt 22 located below the guide mechanism 1 is lower than the height of the other end thereof, that is, the height of the feeding end of the conveyor belt 22 is lower than the discharging end thereof, and the inclination angle of the baffle 21 is the same as the inclination angle of the conveyor belt 22;

[0037] Among them, in this embodiment, the baffle 21 located on the left side of the conveyor belt 22 is the first baffle, and the baffle 21 located on the right side of the conveyor belt 22 is the second baffle. The height of the second baffle is higher than the first baffle, and the height of the side of the conveyor belt 22 adjacent to the first baffle is lower than the height of the side adjacent to the second baffle.

[0038] The oblique upward arrangement of the conveyor belt 22 ensures that the rollers 5 do not move too fast due to the influence of gravity during the upward transportation process, effectively avoiding the problem of collision damage between the rollers 5 due to uncontrolled movement speed.

[0039] The conveyor belt 22 is set to be inclined toward one side of its length direction, so that the roller 5 that falls on the conveyor belt 22 can slide along the inclined conveyor belt 22, and finally the axial direction of the roller 5 is the same as the moving direction of the conveyor belt 22. The roller 5 can move upward under the drive of the conveyor belt 22 without rotating around the axis, which effectively improves the conveying effectiveness of the conveyor belt 22 set obliquely on the roller 5.

[0040] It can be understood that the width of the baffles 21 on both sides of the conveyor belt 22 is greater than the conveyor belt 22, that is, the upper surface of the baffles 21 is higher than the conveyor belt 22, so as to shield the rollers 5 and prevent the rollers 5 from sliding outward when sliding along the conveyor belt 22.

[0041] Since the rollers 5 are very likely to gather on the conveyor belt 22 during the process of falling onto the conveyor belt 22 for angle adjustment, collisions are likely to occur. For example, when the rollers 5 fall onto the conveyor belt 22 and their axial directions are perpendicular to the moving direction, the rollers 5 are very likely to rotate in place around the axis and not move with the conveyor belt 22. The next roller 5 that falls onto the conveyor belt 22 is very likely to collide with the rotating roller 5.

[0042] The conveying mechanism 2 is supported by a first bracket 3. Two first brackets 3 are provided, one at each end of the conveying mechanism 2. The first bracket 3 consists of a base and two support rods relatively installed on the base. The support rods are retractable structures. Each support rod is hinged to the conveying mechanism 2, so that the upward inclination angle of the conveying mechanism 2 and the inclination angle of the conveyor belt 22 toward the side can be adjusted by adjusting the telescopic length of the support rod.

[0043] In order to prevent the roller 5 from falling onto the conveyor belt 22 and gathering and colliding, a guide mechanism 1 is provided. The guide mechanism 1 consists of a first guide portion 11, a second guide portion 12 and a third guide portion 13. The first guide portion 11 and the second guide portion 12 both have a U-shaped cross-section. The first guide portion 11 is connected to the discharge port of the circular surface grinder. The other end of the first guide portion 11 is connected to the second guide portion 12 through the third guide portion 13. The second guide portion 12 is located above the conveyor belt 22.

[0044] The axial direction of the first guide portion 11 is perpendicular to the axial direction of the conveying mechanism 2, and the discharge end of the first guide portion 11 is located above the conveying mechanism 2. The first guide portion 11 is composed of two first side plates and a second bottom plate. The first side plates are fixedly mounted on both sides of the second bottom plate. The second bottom plate is arranged obliquely downward toward the direction close to the conveying mechanism 2 and is inclined toward the moving direction of the conveyor belt 22 (which can also be understood as toward the second guide portion 12).

[0045] The axial direction of the second guide portion 12 is perpendicular to the axial direction of the first guide portion 11. The second guide portion 12 is adjacent to the discharge end of the first guide portion 11 and is located below the discharge end of the first guide portion 11. The second guide portion 12 is located above the conveyor belt 22. The roller 5 in the first guide portion 11 is guided to the conveyor belt 22 through the second guide portion 12.

[0046] The axial direction of the second guide portion 12 is parallel to the axial direction of the conveyor belt 22. The second guide portion 12 is composed of two second side plates and a third bottom plate. The two second side plates are fixedly installed on both sides of the third bottom plate. The third bottom plate is arranged obliquely downward and inclined toward the direction in which the conveyor belt 22 is inclined, that is, the third bottom plate is inclined toward the side with a lower height of the conveyor belt 22 (it can also be understood that the inclination direction of the third bottom plate is the same as the inclination direction of the conveyor belt 22).

[0047] The third guide portion 13 is an arc-shaped groove structure, which serves as a transition and is used to connect the discharge end of the first guide portion 11 with the feed end of the second guide portion 12. It consists of two arc-shaped third side plates and an arc-shaped fourth bottom plate. The two third side plates are fixedly installed on both sides of the fourth bottom plate. The fourth bottom plate has a slope toward the second guide portion 12 and is inclined in the direction in which the second bottom plate and the third bottom plate are inclined.

[0048] Under the joint action of the first guide part 11, the second guide part 12 and the third guide part 13, the roller 5 can adjust its posture in advance before rolling onto the conveyor belt 22, so that the roller 5 finally slides onto the conveyor belt 22 with the axial direction being the same as the conveying direction of the conveyor belt 22, thereby ensuring that the roller 5 can move with the conveyor belt 22 in time when falling onto the conveyor belt 22, and will not rotate around the axis in place, which greatly improves the conveying efficiency of the conveyor belt 22 and avoids the occurrence of aggregation and collision of the rollers 5.

[0049] In order to further improve the conveying efficiency of the conveyor belt 22, a number of anti-skid grooves 221 are set on the surface of the conveyor belt 22. The anti-skid grooves 221 are perpendicular to the conveying direction of the conveyor belt, and the anti-skid grooves 221 are arranged at intervals along the length direction of the conveyor belt to increase the friction between the surface of the conveyor belt 22 and the roller 5, thereby improving the follow-up performance of the roller 5 and the conveyor belt 22.

[0050] The guide mechanism 1 is supported by a second bracket 4 , which is also a telescopic structure for adjusting the height of the guide mechanism 1 .

[0051] Example 2

[0052] In another typical embodiment of the present invention, a working method of a roller discharge device of a circumferential surface grinding machine is provided, which is specifically as follows:

[0053] After the circumferential surface of the roller 5 is machined, the telescopic cylinder on the circumferential surface grinding machine pushes the machined roller 5 from the discharge port into the first guide portion 11;

[0054] After being guided by the first guide portion 11 , the third guide portion 13 and the second guide portion 12 in sequence, the roller 5 falls onto the conveyor belt 22 in an axial direction that is the same as the moving direction of the conveyor belt 22 and is finally conveyed to a designated position by the conveyor belt 22 .

[0055] Among them, since the bottom plates of the first guide part 11, the second guide part 12 and the third guide part 13 are all inclined toward the same side, while guiding the roller 5, the roller 5 is tilted by the influence of gravity and the inclined surface. The roller 5 moves in the guide mechanism 1 with an axial posture that is the same as its moving direction, and finally falls onto the conveyor belt 22 with an axial posture that is the same as the moving direction of the conveyor belt 22. The roller 5 can be taken away by the conveyor belt 22 in time, avoiding the occurrence of aggregation and collision.

[0056] Since the conveyor belt 22 is also tilted to one side and is set obliquely upward, it can ensure that the roller 5 always maintains its axial posture in the same direction as the moving direction of the conveyor belt 22 during the conveying process, and the moving speed will not be accelerated due to the influence of gravity, thereby avoiding the occurrence of roller 5 collision due to excessive speed.

[0057] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
