の被研削材から所望径のローラ、ドラムを得るための自
動研削装置に関する。[Detailed Description of the Invention] This invention provides roller-shaped (cylindrical, truncated conical, cylindrical, etc.)
This invention relates to an automatic grinding device for obtaining rollers and drums of a desired diameter from materials to be ground.

公知である。Conventionally, in grinding devices that obtain rollers and drums from the material to be ground, in order to easily grind cylindrical or non-cylindrical materials, a grinding tool is pressed against the surface of the rotating material to be ground. It is known that a grinding tool is moved relatively from one end of a material to be ground to the other to form a roller or a drum.

問題点を解決することを目的とする。In such a grinding device, the grinding speed of the material to be ground in the radial direction is constant, so if there is a protrusion on the material to be ground, that protruding portion will remain even after the grinding is finished. Further, near the end of the work, it is desirable for accuracy to perform the grinding at a slower grinding speed, but since the grinding speed is constant, the amount of grinding is large even near the end, which poses a problem in terms of accuracy. Precision can be increased by reducing the amount of grinding from the start, but this poses a problem in terms of workability. This invention aims to solve the above problems.

である。In order to achieve this object, in the automatic grinding device of the present invention, a detector for detecting the diameter of the material to be ground is arranged in the conventional device described above, and this detector is attached to the axis of the material to be ground. The grinding tool is relatively movable in the direction, and the larger the difference between the detected diameter of the detector and the set diameter, the smaller the relative moving speed between the grinding tool and the material to be ground.

The calculation unit 42 which receives the detection value X6 of the gap detector 31, the movement value 2 of the movement amount detector 40, and the reference value L of the setting device 41 detects the diameter of the material to be polished based on each value.Diameter d= 2(L-x-l). Detection diameter d of the calculating section and desired diameter D of the setting device 41. The comparison unit 43 inputs 6 detected diameter d is desired diameter D.
If it is larger, that is, d>DO, the difference d-DO
is output to the speed command unit 44, and if d≦DO, a signal is output to the storage unit 45. This storage section 45 is the comparison section 4
When the signal from 3 is input, the memory signal is outputted until an external signal a is input, such as to start grinding the next new material to be ground, and the right edge detector 32 or the left edge detector is output via the OR circuit An AND circuit 47 is configured to stop the support motor 6 when a signal is issued from either one of the devices 33.

作を説明する。Note that the above speed signal becomes 6. For example, as shown in FIG. 6, when the difference d - DO is less than D1, the speed signal becomes 1,
If D2 or more, it becomes low speed signal 2, and D, and D2
If the value is between D1 and D2, the value gradually decreases from D1 to V2. These Dl and D2 are.
This is to determine the upper and lower limits of the moving speed (grinding speed) so that it does not become extremely slow or fast. It is set appropriately depending on the type of the grinding tool 13 and the material to be ground A. Note that the above-mentioned zero signal refers to a time when the speed signal is outputting zero. This invention... The configuration is as follows, and the operation will be explained next.

By moving the workpiece A toward the center, the support parts 8a and 9a center and support the workpiece A. The right end detector 32 and the left end detector 33 are adjusted so as to correctly detect that the grinding tool 13 is detached from the right end and left end of the material to be ground A.

る。Furthermore, the weight 27 is adjusted so that the 6-grinding tool 13 appropriately contacts the material to be ground A, and the height of the support arm 20 is adjusted by driving the lifting motor 21. Next, after the 6-gap detector 31 is brought close to the material A to be ground so as not to come into contact with it, each of the 6 motors 6, 12, and 22 is operated to start grinding.

ことになる。Initially, the detected diameter d is the desired diameter D. Since it is sufficiently large compared to , the support motor 6 is operated at low speed, but as the diameter of the material to be ground A gradually becomes smaller, the support motor 6 becomes faster. However, if the diameter of the workpiece A to be ground is not uniform, the support motor 6 will be driven at low speed where the diameter is large, and the support motor 6 will be driven at high speed where the grinding amount is large 6 and where the diameter is small. Since the grinding amount is reduced, the diameter of the material to be ground A becomes completely uniform by the time the grinding is completed. During the above-mentioned grinding, when the right edge detector 32 issues a right edge signal, the support motor 6 is controlled so that the rotation support platform 3 moves to the right, and conversely, when the left edge detector 33 issues a left edge signal, the rotation support 3 moves to the right. Since the rotary support table 3 is controlled to move to the left, the rotary support table 3 reciprocates during grinding.

At that point, the 6-AND circuit 47 outputs a stop signal to the speed command section 44.

Note that when the feed command unit 44 stops the support motor 6, the grinding tool motor 22 and the abrasive material rotation motor 12 are simultaneously stopped.
stop, and. The weight motor 22 may be operated so that the grinding tool 13 does not come into contact with the material A to be ground. In the above embodiment, the grinding unit 14 may be moved instead of moving the material A to be ground.

If the diameter of the material to be ground A is detected during grinding. light 6
It may be anything that uses other materials. Further, the right end detector 32 and the left end detector 33 may be combined together as a detector for detecting that the grinding tool 13 has separated from the workpiece A, and the type of the detector is not limited. . This invention... As described above, the grinding tool is brought into contact with the material to be ground, the tool is moved relatively from one end of the material to the other, and the speed of movement is changed according to the diameter of the material to be ground. Therefore, the diameter of the ground roller 6 drum is uniform, and the precision is also high.

の自動研削装置。[Scope of Claims] 1. A grinding device that is equipped with a rotary support on a machine base that rotatably supports both ends of a roll-shaped material to be ground so as to be rotatable about its axis, and a grinding tool that is pressed against the surface of the material to be ground. In the grinding apparatus, the unit is provided near the rotation support base, and the rotation support base is provided with a moving mechanism that relatively moves the grinding tool in the axial direction of the workpiece while the grinding tool is in pressure contact with the workpiece. A detector for detecting the diameter of the material to be ground is arranged near the material to be ground, and the moving mechanism allows the detector to move freely in the axial direction with respect to the material to be ground. An automatic grinding device comprising: a control section that reduces the relative moving speed of the moving mechanism as the difference between the set diameter and the set diameter increases. 2 The detector is a gap detector that detects the distance from a predetermined position to the surface of the material to be ground, and the diameter of the material to be ground is detected from the distance between the predetermined position and the axis of the material to be ground. 2. The automatic grinding device according to claim 1, wherein the automatic grinding device is calculated based on a value obtained by subtracting a detection value of the grinder.
