Description

TECHNICAL FIELD

[0001] The present application relates to the field of feeding devices, in particular to a feeding device and method for an end face grinder. BACKGROUND

[0002] Rollers are located between the outer ring and the inner ring of the bearing, and the friction is reduced by the rolling of the rollers. In the process of rough machining the rollers, the end face of the roller is often machined by an end face grinder, such as a centerless grinder or a roller double-end face grinder. The outer peripheral wall of the roller can be polished by the centerless grinder, and the double-end face can be polished by the roller double-end face grinder.

[0003] Before the end face of the roller is ground by the end face grinder, the roller needs to be fed. At present, the feeding mode is usually realized by a vibrating screen, but its feeding efficiency is low. A feeding device for a roller machining production line is disclosed in Chinese patent (publication number: CN112171508A), which realizes the temporary storage and conveying of the roller through a hopper and a rotating roller. The rotating roller is arranged obliquely to enable the roller to be output. The rotating roller drives the roller to have a tendency to move upward, but it is suitable for cylindrical rollers. For drum-shaped rollers with thick middle and thin ends, the parallel arrangement of the rotating rollers cannot meet the feeding of the rollers. During the conveying process of the drum-shaped rollers along the rotating rollers, the posture of the drum-shaped rollers is prone to change, which cannot be smoothly conveyed downstream along the rotating rollers, resulting in the accumulation of the rollers, affecting the supply efficiency of the rollers, and further affecting the working efficiency of the entire grinding machining process.

[0013] Further, the hopper is arranged at one end of the outlet end which is away from the arranging groove, the outlet end of the arranging groove is connected to a conveying belt through a guide groove, and the conveying belt is provided with a conveying groove which accommodates the roller.

[0014] Further, the arranging roller group and the hopper are respectively arranged on a support, and the support is connected with a vibration unit.

[0015] Further, one end of the support is rotatably connected to a base, the support and the base are connected through a lifting support, the lifting support can drive the support to rotate, so that the inclination angle of the arranging roller group relative to the horizontal plane is changed, and the first roller and the second roller are connected to the same driving element.

[0016] The second object of the present application is to provide a working method using the end face grinder feeding device as described in the first object, which comprises:

[0017] The roller to be fed is put into the hopper and gradually enters the arranging groove from the hopper;

[0018] The roller entering the arranging groove is adjusted in posture under the driving of the first roller and the second roller, until the axis of the roller is consistent with the axis of the arranging groove, and then the roller is output from the discharge port to the outside of the hopper;

DETAILED DESCRIPTION

[0034] Embodiment 1

[0035] In a typical embodiment of the present application, as shown in Figures 1-6 , an end face grinder feeding device is given.

[0036] The current end face grinder feeding device can feed and convey cylindrical rollers, but it is not suitable for conveying drum-shaped rollers. In the conveying process, the drum-shaped rollers are easily changed in posture due to their shape, which causes the rollers to be stuck and unable to be conveyed, affecting the stable operation of the upstream and downstream of the feeding device and reducing the efficiency of grinding processing.

[0037] Based on this, in the present embodiment, an end face grinder feeding device is given, which is configured to adjust and convey the drum-shaped rollers according to their structural characteristics. The sorting roller group 1 includes two rollers with different inclinations, and the sorting groove 5 formed between the rollers is used to receive and convey the rollers. In the area close to the hopper 2, the height difference of the rollers is large, which is beneficial to maintaining the posture of the rollers and enabling the rollers to move smoothly along the sorting groove 5. In the position close to the outlet end 6, the height difference of the rollers gradually decreases, enabling the rollers to be conveyed to the downstream process in a normal posture, reducing the accumulation problem and improving the processing efficiency.

[0038] Next, the above-mentioned end face grinder feeding device will be described in detail in conjunction with the drawings.

[0039] Referring to Figure 1The end face grinding machine feeding device includes a conveyor belt, a guide trough 16, a material handling roller group 1 and a hopper 2 arranged in sequence. The material handling roller group 1 receives the rollers output from the hopper 2 and adjusts the rollers' posture before conveying them to the guide trough 16. The conveyor belt supplies the rollers in the guide trough 16 to the end face grinding machine, where the end face of the rollers is ground.

[0040] The feeding roller assembly 1 is arranged at an angle, and the hopper 2 is mounted at the higher end of the feeding roller assembly 1. The higher end of the feeding roller assembly 1 is the inlet end that picks up the rollers from the hopper 2, and the corresponding lower end of the feeding roller assembly 1 is the outlet end 6 that outputs the picked-up rollers. One end of the guide chute 16 is connected to the outlet end 6 of the feeding roller assembly 1, and the other end is connected to the beginning of the conveying path of the conveyor belt. Along the conveying direction from the hopper 2 to the conveyor belt, the overall height gradually decreases, allowing the rollers to fall and move under the action of gravity.

[0041] Optionally, the feeding roller assembly 1 and the hopper 2 are respectively installed on the support 17. The support 17 is connected to a vibration unit 18. The vibration unit 18 applies vibration to the feeding roller assembly 1 and the hopper 2, which can promote the output of the rollers in the hopper 2. The vibration combined with gravity causes the rollers to move on the inclined feeding roller assembly 1.

[0042] The feed roller assembly 1 carries continuously distributed rollers. After the posture is adjusted, the roller axis is aligned with the axis of the feed roller assembly 1, and the rollers are in a horizontal position. Multiple rollers are arranged sequentially along the axis of the feed roller assembly 1.

[0043] See Figure 2 , Figure 5 A V-shaped material feeding groove 5 is formed on the material feeding roller assembly 1. The rollers are located inside the material feeding groove 5 and move and convey under the drive of the material feeding roller assembly 1. Figure 6 The material handling roller group 1 includes a first roller 3 and a second roller 4 arranged at an inclination. The inclinations of the first roller 3 and the second roller 4 are different. The outer circumferential surfaces of the first roller 3 and the second roller 4 together form a material handling groove 5. A gap is left between the first roller 3 and the second roller 4 to avoid interference between the rotation of the first roller 3 and the second roller 4.

[0044] The lower end of the material feeding trough 5 is the outlet end 6, and the higher end is the inlet end. The first roller 3 and the second roller 4 are at the same height as the outlet end 6 and are arranged horizontally. The heights of the first roller 3 and the second roller 4 at the inlet end are not equal. A hopper 2 is set in this area of ​​unequal height. The hopper 2 puts rollers into this position. Under the action of the first roller 3 and the second roller 4, the rollers are adjusted from other postures to a horizontal posture, and the outer circumferential surface of the rollers contacts the first roller 3 and the second roller 4 at the same time.

[0045] The two rollers are co-inclined but have different inclination degrees, and a material arranging groove 5 is formed between the two rollers. The material arranging groove 5 gradually changes in shape along the length direction, and the height difference of the rollers is large in the area close to the hopper 2, which is beneficial to keep the posture of the rollers. Under the rotation of the first roller 3 and the second roller 4, the rollers have a tendency to move towards the roller with a higher side, which avoids the rollers from changing from the lying posture to other postures unsuitable for conveying when the rollers are subjected to the action of the first roller 3 and the second roller 4, and enables the rollers to move and output along the material arranging groove 5 smoothly.

[0046] The height difference of the rollers gradually decreases close to the outlet end 6, which enables the rollers to be conveyed to the downstream process in a normal posture, reduces the stacking problem and improves the processing efficiency.

[0047] It should be noted that the first roller 3 and the second roller 4 rotate in the same direction, and the inclination degrees of the first roller 3 and the second roller 4 are different. The force state of the rollers subjected to the first roller 3 is different from that subjected to the second roller 4, which changes the force state of the rollers subjected to the rollers arranged in parallel in the prior art. The rollers keep an unbalanced state by using the force deviation, thereby promoting the movement of the rollers along the material arranging roller group 1 and avoiding the stacking problem caused by the force balance of the rollers staying at a certain position, and improving the supply efficiency of the rollers.

[0048] In addition, one end of the support 17 is rotationally connected to the base 19, and the support 17 and the base 19 are connected through a lifting support 20. The lifting support 20 can drive the support 17 to rotate to change the inclination angle of the material arranging roller group 1 relative to the horizontal plane. The first roller 3 and the second roller 4 are connected to the same driving element.

[0049] The lifting support 20 can adopt a structure of a slide rod cooperating with a sleeve. The slide rod is connected to the support 17, and the sleeve is connected to the base 19. The end of the slide rod can be connected to the support 17 through a rotating structure. The sleeve is sleeved on the slide rod. When the inclination angle of the support 17 is changed, the slide rod moves along the sleeve. After the angle is adjusted, the relative position of the slide rod and the sleeve is fixed, so as to fix the inclination angle of the material arranging roller group 1.

[0050] As shown in Figure 3 The hopper 2 is arranged above the material arranging roller group 1. The bottom of the hopper 2 is provided with a strip-shaped opening 7 communicating with the material arranging groove 5. The strip-shaped opening 7 is arranged along the axial direction of the material arranging roller group 1. The end of the hopper 2 is provided with a discharge port 8 through which the rollers pass. The discharge port 8 communicates with the strip-shaped opening 7.

[0051] The hopper 2 is provided with a baffle 9. The baffle 9 divides the hopper 2 into a storage area 10 and a material arranging area 11 which are arranged in sequence along the axial direction of the material arranging roller group 1. Figure 4 As shown in

[0052] A pressing rod 14 is arranged above the sorting groove 5 downstream of the hopper 2, the pressing rod 14 is arranged in a spaced manner with the sorting groove 5, and a feeding channel 15 for the rollers to pass through is formed between the pressing rod 14 and the sorting groove 5.

[0053] The hopper 2 is divided into functional areas by arranging the baffle 9 in the hopper 2, and the posture of the rollers in the sorting groove 5 is adjusted by arranging the stopper 12 in the sorting area 11. Since the height difference between the first roller 3 and the second roller 4 is relatively large at this position, the posture of the rollers output from the storage area 10 is adjusted from the sorting area 11, which can avoid the rollers from falling outside, and ensure that the rollers can be within the range of the hopper 2. The rollers after posture adjustment can be smoothly output to the outside of the hopper 2 in the required posture.

[0054] The pressing rod 14 is arranged in the sorting groove 5 downstream of the hopper 2 to control the posture of the rollers after being output from the hopper 2. As the rollers gradually approach the outlet end 6 of the sorting groove 5, the rollers are kept moving to the outlet position in a posture with the axis transversely placed, which reduces the posture change of the sorting groove 5 again during the conveying process. In combination with the stopper 12, the posture control of the rollers in the whole conveying process is realized, which improves the conveying smoothness and the accuracy of the roller feeding.

[0055] As shown in Figure 4 , according to the conveying adjustment difficulty of the posture of the rollers, the action time of the stopper 12 in the hopper 2 can be adjusted. The size of the sorting area 11 is changed to change the time of the rollers passing through the sorting area 11, so as to change the space size and operation time for the posture adjustment in the sorting area 11.

[0056] The size of the sorting area 11 can be realized by changing the position of the baffle 9. The hopper 2 is provided with a chute 13 on the inclined side surface, and the baffle 9 is matched with the chute 13. The baffle 9 can slide and adjust the relative position with the hopper 2 in the axial direction of the sorting roller group 1.

[0057] In order to avoid the rollers from deviating and falling when being output from the area of the hopper 2, a second baffle is connected to the outer wall of the hopper 2. The second baffle is located on both sides of the discharge port 8 and between the pressing rod 14 and the discharge port 8. The hopper 2 is arranged at one end away from the outlet end 6 of the sorting groove 5. The outlet end 6 of the sorting groove 5 is connected to the conveying belt through the guide chute 16. The conveying belt is provided with a conveying groove for accommodating the rollers.

[0058] Embodiment 2

[0059] In another typical embodiment of the present application, as shown in Figures 1-6 , a working method is given.

[0060] The end face grinder feeding device as described in embodiment 1 comprises the following steps:

[0061] The roller to be fed is put into the hopper 2, and gradually enters the sorting groove 5 from the hopper 2;

[0062] The roller entering the sorting groove 5 adjusts the posture under the driving of the first roller 3 and the second roller 4, until the roller is consistent with the axis of the sorting groove 5, and is output from the discharge port 8 to the outside of the hopper 2;

[0063] The roller after adjusting the posture moves along the sorting groove 5 under the driving of the sorting roller group 1, and the roller maintains the posture and is output from the outlet end 6 of the sorting groove 5.

[0064] Among them, the first roller 3 and the second roller 4 have different inclinations, so that the roller can smoothly enter between the sorting grooves 5, and promote the movement of the roller to the outlet end 6.

[0065] During the action of the sorting roller group 1 on the roller, vibration can be applied to the sorting roller group 1 and the hopper 2 at the same time, the vibration unit 18 is arranged to vibrate the sorting roller group 1 and the hopper 2 together, promote the output of the roller in the hopper 2 to the sorting groove 5, and at the same time promote the roller in the sorting groove 5 of the sorting roller group 1 to the downstream conveying, improve the conveying efficiency, and reduce the accumulation problem caused by the blockage in the conveying process.

[0066] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
