TECHNICAL FIELD

[0001] The present application relates to a material sorting device, in particular to a cone roller overturning and removing device. BACKGROUND

[0002] At present, the double-roller feeding mode is generally used to convey materials in the cone roller processing industry.

In the existing processing method, the roller surface recognition equipment is used for surface recognition and overturning adjustment. For example, a domestic application with the application number CN201610830965.2 discloses an automatic feeding and surface recognition machine for cone roller bearings, which includes a feeding device and a surface recognition system.

[0027] The following specific examples are merely an explanation of the present application, and are not a limitation of the present application. Those skilled in the art can make modifications to the present examples without creative contribution after reading the present specification, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.

[0028] The present application will be described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] As the current taper roller 0 processing industry generally uses double roller feeding mode to convey materials, but when the double roller conveying material enters the material channel, the taper roller 0 has its center of gravity located at the large end, resulting in some taper rollers 0 entering the material channel with the large end first. When the turnover roller enters the grinding device, the large end is ground first, resulting in excessive grinding of the grinding wheel, causing the grinding wheel to drop, the guide roller to be squeezed, and the tool to be damaged. Figure 6 As shown in

[0031] According to Figures 1 to 5 A taper roller turnover and rejection device, comprising: a discharge mechanism arranged at the inlet end of the bottom plate 1, comprising a discharge block 3-1, the discharge block 3-1 is provided with a discharge passage A allowing the taper roller 0 to pass through, and the first positioning is realized through the discharge passage A to accurately dock the discharge end of the previous link device and ensure the smooth entry of the taper roller 0.

[0032] The discharge block 3-1 is fixed on the bottom plate 1 by the discharge block quick mounting bolt 7, and the discharge block 3-1 is provided with an adjusting waist-shaped hole 7 corresponding to the discharge block quick mounting bolt 7. The discharge block 3-1 can be fine-tuned in position by screwing the discharge block quick mounting bolt 7 in the adjusting waist-shaped hole 7. After multiple uses, the position of the discharge block 3-1 may be tilted due to the impact of the falling taper roller 0, and the position of the discharge block 3-1 can be readjusted by a pair of adjusting waist-shaped holes 7 and discharge block quick mounting bolts 7.

[0033] The bidirectional pushing mechanism is arranged below the discharge passage A and comprises a first telescopic first telescopic cylinder 4-1, a second telescopic second telescopic cylinder 4-7, and a pushing block 4-6. The first telescopic first telescopic cylinder 4-1 is connected horizontally to the bottom plate 1 by a fixing screw 10, and the second telescopic second telescopic cylinder 4-7 is connected longitudinally to the bottom plate 1. The second telescopic second telescopic cylinder 4-7 is connected to the bottom plate 1 by a cylinder mounting plate 2. The pushing block 4-6 is connected to the first telescopic first telescopic cylinder 4-1, and the pushing block 4-6 is connected to the second telescopic second telescopic cylinder 4-7 on the side away from the bottom plate 1. The pushing block 4-6 is provided with a screening passage B, and the product is discharged from the discharge passage A and enters the feeding movement state or the rejection movement state according to its discharge condition. In the feeding movement state, the pushing block 4-6 is controlled by the first telescopic first telescopic cylinder 4-1 to move left and right on the horizontal plane; in the rejection movement state, the pushing block 4-6 is controlled by the second telescopic second telescopic cylinder 4-7 to move longitudinally on the horizontal plane.

[0034] The screening mechanism includes a discharge block 3-1, the discharge block 3-1 is provided with a feeding channel D and a rejection channel C, the feeding channel D can be connected with the screening channel B in a feeding movement state, and the rejection channel C can be connected with the screening channel B in a rejection movement state. By respectively setting two different channels, the entering conical roller 0 can be precisely divided, and compared with the existing face recognition and overturning device, the overturning step is saved, and the efficiency is greatly improved.

[0035] Further, the quick mounting bolt 14 of the discharge block cooperates with the waist-shaped hole 13 of the discharge block to realize quick mounting and position fine adjustment.

[0036] The trigger mechanism is arranged in the discharge block 3-1 and includes a micro switch 5-7 and a top rod 5-2, the micro switch 5-7 is located between the feeding channel D and the first telescopic cylinder 4-1, the upper end of the micro switch 5-7 is connected with a top rod seat 5-3, the upper end of the top rod seat 5-3 is connected with the top rod 5-2, and the top rod 5-2 is arranged outside the discharge block 3-1.

[0037] The embodiment triggers the trigger mechanism through mechanical collision, effectively identifies the orientation of the conical roller 0, sets the feeding channel D and the rejection channel C respectively, cooperates with the first telescopic cylinder 4-1 and the second telescopic cylinder 4-7, realizes rapid and automatic rejection, and has high degree of automation.

[0038] When operating, according to the length and outer diameter of the tapered roller 0, the feeding pipe A-1 with appropriate specification is selected, the feeding pipe A-1 is sleeved in the discharging channel A, and by replacing the feeding pipe A-1 with different specifications, it is ensured that the tapered roller 0 keeps the same orientation when moving in the discharging channel A and cannot be turned over. Meanwhile, the gap between the discharging block 3-1 and the feeding block is adjusted, the gap is 1 mm larger than the length of the tapered roller 0, according to the outer diameter of the tapered roller 0, the replaceable pushing block 4-6 with corresponding size is selected and locked by the screws 11 and 12, and the feeding pipe A-1 is adjusted to be flush with the end surface of the discharging block 3-1. When working, the small end of the tapered roller 0 contacts the ejector rod 5-2 downward, the ejector rod 5-2 is pushed downward to trigger the micro switch 5-7, the first telescopic cylinder 4-1 runs forward, the tapered roller 0 is pushed to the top of the discharging channel A, the small end of the tapered roller 0 falls downward, if the tapered roller 0 is turned over, the large head is downward, the concave part in the large head does not push the ejector rod 5-2 downward, the micro switch 5-7 is not triggered, the first telescopic cylinder 4-1 returns to the original position after two seconds without triggering the signal, the second telescopic cylinder 4-7 starts to run from the initial state, the second telescopic cylinder 4-7 pushes the pushing block 4-6 to the bottom plate 1, pushes the turned over tapered roller 0 to the top of the rejection channel C, and the tapered roller 0 falls into the rejection channel C, so that the turned over tapered roller 0 is effectively rejected, the reverse step is omitted, the correct orientation of the tapered roller 0 does not affect the feeding of the next link, effectively solves the abnormal damage of the equipment, grinding wheel and tool caused by the turned over roller, and the device has strong automation, low failure rate and high speed. Further to the embodiment, the rejection channel C is connected with a circulating transportation device, the turned over tapered roller 0 is collected and then fed into the discharging channel A, so that the waste is reduced and the turning step is omitted.

[0039] The device also has an initial state, in which the axis of the ejector rod 5-2 coincides with the axis of the screening channel B.

[0040] The first telescopic cylinder 4-1 includes a first telescopic rod 4-1-1, a connecting block 4-2 is arranged on the first telescopic rod 4-1-1 and faces the pushing block 4-6, a groove 4-2-1 is arranged in the connecting block 4-2 and faces the first telescopic rod 4-1-1, a sliding block 4-5-1 is protruded on the pushing block 4-6 and corresponds to the groove 4-2-1, the sliding block 4-5-1 is slidably connected with the groove 4-2-1, and a limiting hole is arranged in the sliding block 4-5-1 and longitudinally penetrates through the sliding block 4-5-1, a guide rod 6-1 is inserted into the limiting hole, one end of the guide rod 6-1 is connected with the bottom plate 1 through a positioning plate 6-2, and the other end of the guide rod 6-1 is provided with a limiting plate 6-3. When the sliding block 4-5-1 is connected with the limiting plate 6-3, the pushing block 4-6 is in the initial state and is ready to be connected with the tapered roller from the discharging channel A.

[0041] The sliding block 4-5-1 is fixed to the connecting strip 4-5, the connecting strip 4-5 is fixedly connected with the pushing block 4-6 through screwing, and the length of the groove 4-2-1 is greater than the length of the sliding block 4-5-1. The spring 6-5 is sleeved on the guide rod 6-1, one end of the spring 6-5 is connected with the positioning plate 6-2, and the other end of the spring 6-5 is connected with the sliding block 4-5-1. The spring 6-5 is used for automatically returning after the non-correctly-oriented conical roller 0 is removed.

[0042] The path length of the pushing block 4-6 in the pushing state is less than the width of the connecting strip 4-5. Since the second telescopic rod of the second telescopic cylinder 4-7 needs to be in contact with the pushing block 4-6 to push, in the extreme case, the second telescopic rod is in direct contact with the pushing block 4-6 in the removing state, so that the pushing block 4-6 in the pushing state moves, the second telescopic rod always slides with the pushing block 4-6, which damages the pushing block 4-6. When the width of the connecting strip 4-5 is wide enough, the second telescopic rod only causes sliding wear on the surface of the connecting strip 4-5, and does not damage the body of the pushing block 4-6. The pushing block 4-6 is connected with the connecting strip 4-5 through the pushing bolts 11 and 12, and only the connecting strip 4-5 needs to be replaced in the later period, which greatly reduces the cost of replacing the pushing block 4-6 in production.

[0043] In the vertical projection, the axis of the discharging channel A coincides with the axis of the removing channel C. At this time, in the removing state, only the second telescopic cylinder 4-7 needs to work, and the industrial control path is also the shortest, which greatly improves the removing efficiency.

[0044] Further, the top rod 5-2 protrudes 1-2 mm from the top surface 1-2 of the discharging block 3-1. The bottom of the pushing block 4-6 is recessed upward and provided with a passing groove 4-6-1 corresponding to the top rod 5-2.

[0045] The above only discloses preferred embodiments of the present application, and of course cannot limit the scope of the present application. Therefore, equivalent changes made according to the claims of the present application still belong to the scope covered by the present application.
