材の径を容易に確認できないという問題がある。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. In such a grinding device, the grinding tool is pressed against the material to be ground, so even if there is a protrusion on the material to be ground, it is possible to easily grind the protrusion to a constant diameter. Since the grinding tool is not fixed, there is a problem in that the diameter of the material to be ground cannot be easily confirmed during grinding.

An object of the present invention is to provide an automatic grinding device capable of automatically grinding.

Comparison unit 43 that receives as input the detected diameter d of the calculation unit and the desired diameter do of the setting device 41
If the detected diameter d is larger than the desired diameter do, then d>
If 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. When the signal from the comparator 43 is input, the storage section 45 outputs a storage signal until an external signal a for starting grinding of the next new material to be ground is input.

When the stop signal is input, until external signal 3 is input,
A zero signal is output to stop the rotation of the support motor 6, and when the right end signal is input, the material to be ground A is
When the support stand motor 6 is rotated to move the rotation support stand 3 supporting it to the right, and the left end signal is input,
The support stand motor 6 is reversely rotated to move the rotary support stand 3 to the left. Note that the speed signal has a difference dd as shown in FIG. 6, for example. If l) is less than or equal to 1, it becomes a high-speed signal v1; if it is 1) or more, it becomes a low-speed signal v2; and if it is between 1) 1 and 1) 2, it becomes a high-speed signal v1. As it reaches D2, it gradually becomes smaller from vl to v2.

Adjust. Further, the weight 27 is adjusted so that the grinding tool 13 properly contacts the material to be ground A, and the height of the support arm 20 is adjusted by driving the lifting motor 21.

了するまでには完全に一様となる。Next, after the gap detector 31 is brought close to the workpiece A to be in contact with it, each motor 6.12° 22 is operated to start grinding. Initially, the detected diameter d is the desired diameter dO
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 is not uniform, the support motor 6
Since it is driven at a low speed, the amount of grinding is large, and the support motor 6 is driven at a high speed in areas where the diameter is small, so the amount of grinding of e is small, and the grinding of the diameter of the material to be ground A is completed. By then it will be completely uniform.

The support motor 6 is used to move the rotation support 3 to the right side.
is controlled, and conversely, when the left end detector 33 issues a left end signal, the rotary support base 3 is controlled to move to the left, so the rotary support base 3 reciprocates during grinding.

- The support motor 6 is stopped to indicate that the grinding is completed. Note that when the speed command unit 44 stops the support stand mower 6, it simultaneously stops the grinding tool motor 22 and the abrasive material rotation motor 12, so that the grinding tool 13 does not come into contact with the material A to be ground. The weight motor 22 may be operated.

部も形成されないという利点もある。As described above, this invention abuts a grinding tool against a material to be ground, moves the grinding tool relatively from one end of the material to the other, and adjusts the speed of movement in accordance with the diameter of the material to be ground. Since the diameters of the ground rollers and drums are varied, there is an advantage that the diameters of the ground rollers and drums are uniform. Additionally, even if the desired diameter is reached during grinding of the material to be ground, the grinding tool is moved to the end and the grinding is completed, which has the advantage that even the slightest step is not formed on the ground roller or drum. .

３項のいずれかに記載の自動研削装置。[Scope of Claims] +11 A rotary support that rotatably supports the material to be ground is provided on the machine base, and a grinding unit equipped with a grinding tool that is pressed against the surface of the material to be ground is provided near the rotary support. In the grinding device, the grinding tool is provided with a movement mechanism that relatively moves the grinding tool from one end of the workpiece to the other end while the grinding tool is in pressure contact with the workpiece, and the workpiece is mounted near the rotating support base. An automatic grinding device comprising: a detector for detecting a diameter; and a control section for controlling a relative moving speed of the moving mechanism in accordance with a difference between a diameter detected by the detector and a set diameter. (21) The automatic grinding apparatus according to claim 1, wherein the control section is configured to perform control such that the relative movement speed is decreased as the difference between the detected diameter and the set diameter increases. 3) The control section controls the relative movement speed according to the difference between the detected diameter and the set diameter, and also controls the detected diameter and the set diameter while the grinding tool force 1 is moving from one end of the material to be ground to the other. Claim 1 characterized in that when the diameters become equal, the movement of the material to be ground is stopped when it reaches the other end.
Automatic grinding device as described in section. (4) 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 determined from the distance between the predetermined position and the axis of the material to be ground by the gap The automatic grinding device according to any one of claims 1 to 3, wherein the automatic grinding device is configured to calculate based on a value obtained by subtracting a detection value of a detector.
