Abstract

PURPOSE:To move a cylindrical work in the direction of its axial center to be smoothly conveyed while the cylindrical work is rotated, by means of conveying guides diagonally crossing with the running direction of a belt in a position above the belt of a conveyer driven to perform a turning motion. CONSTITUTION:Grooved rollers 4, 5, having on their peripheral surface a large number of belt grooves 4a, 5a, mount endless belts 7 to be engaged, and a pair of conveying guide walls 12, crossing at an angle theta with the running direction of the belt, are provided in the upper of the belt. A work 15, carried into an inlet part between the walls 12, is fed forward along the wall 12 while the work is rotated by the distance of speed component of the crossing angle theta with respect to the wall 12. And the work 15, on which no unreasonable force acts, is conveyed at a fixed speed without causing the work 15 to intrude into the wall 12 and/or the belt 7.

Description

[Detailed Description of the Invention] [Technical Field] The present invention is applicable to wet grinding, in which grinding fluid adhering to a workpiece is blown off by air blowing.
The present invention relates to a conveyance device that rotates and moves a cylindrical workpiece.

[Background technology]

Conventionally, as this type of conveying device, a pair of rollers 1 and 2 made of rubber are set at an angle θ' with their axes as shown in FIGS. The workpieces 3 are arranged so as to be shifted by a certain amount, and are rotated to send the workpiece 3. but,
When the rollers 1 and 2 wear out, there is a problem that the work 3 bites into the rollers, deforming the rollers, and slowing down the feed speed.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a conveyance device that can smoothly convey a cylindrical workpiece while rotating it in the axial direction.

[Disclosure of the invention]

The conveyance device of the present invention includes a rotationally driven belt in the form of a belt conveyor, and a conveyance guide wall provided above the belt and intersecting obliquely with respect to the belt running direction.

Embodiment An embodiment of the present invention is shown in FIGS. 4 to 6. In the figure, reference numeral 4.5 denotes a pair of parallel grooved rollers, which are rotatably supported by a casing 6 with bearings 7. The grooved rollers 4, 5 have a large number of belt grooves 4m, 5m on the circumferential surface, and the grooved rollers 4, 5 each have a belt groove 4m, 5m, respectively.
An endless belt 7 made of rubber or the like is hung between the belts 5a.

The positions of the belt grooves 4a and 5m of both grooved rollers 4.5 are shifted in the axial direction, and the running direction of the belt 7 is different from that of the grooved rollers 4.5.
It is shifted from the axial direction of 5. In the belt groove 6 at one end of the grooved roller 4.5, a belt 9 is placed around a drive pulley 8.
is hung. The drive pulley 8 is fixed to the output shaft of a motor 11 with a reduction gear 10. Motor 11 is fixed to casing 6. A pair of parallel conveyance guide walls 12 are provided above the belt 7, and at the entrance and exit between the conveyance guide walls 12, there are carried-in rollers 13 and discharge rollers 14 for transferring to and from the conveyors in the previous and previous processes. is provided. The conveyance guide wall 12 has grooved rollers 4,
The belt 5 is provided parallel to the axial direction of the belt 7, and intersects with the running direction of the belt 7 at a crossing angle θ. The width between the conveyance guide walls 12 is such that a cylindrical workpiece 15 can be loosely fitted therein. Note that the intersection angle θ is variable. The carry-in U-roller 13 and the carry-out roller 14 are connected to a drive device.

The casing 6 has a quart-shaped bottom wall 11, and a drain outlet 16 is provided at the lower end. An air nozzle (not shown) is provided above between the conveyance guide walls 12.

The workpiece 15 carried into the entrance between the operational conveyance guide walls 12 is placed on the belt 7 by the carry-in pulley 13. The workpiece 15 is a workpiece to which grinding fluid has adhered during the grinding process. The belt 7 is rotated by the drive of the motor 11, and the workpiece 15 is stopped from moving in the belt running direction by the conveyance guide wall 12. Therefore, the workpiece 15 is conveyed only by the velocity component of the intersection angle θ with respect to the conveyance guide wall 12. It is sent forward along the guide wall 12. Also, due to the rotation of the belt 7, the workpiece 1
5 rotates. That is, the workpiece 15 moves in the axial direction while rotating. Since no unreasonable force is applied to the work 15, the work 15 can be transported at a constant speed without being bitten by the transport guide wall 12 or the belt 7. In this way, since the workpiece 15 is sent while being rotated, the cylindrical workpiece 15 can be evenly dried and drained by air blowing. For drying, not only air blowing but also hot air may be used. In conventional wet grinding, the grinding fluid adhering to the workpiece had a negative impact on equipment in subsequent processes, but by drying with this conveyance device, the same effect as dry grinding can be obtained. If the belt 7 is replaced with a flat steel belt or the like, it becomes possible to detect defects such as external scratches while conveying the cylindrical workpiece 15 using a sensing device using a laser beam or the like.

FIG. 8 shows another embodiment. In this example, the angle of the conveyance guide wall 12 with respect to the running direction of the belt 7 can be changed using an adjustment screw 18.

The adjusting screw 18 is fastened to the casing 6 (FIG. 4).

According to this, by changing the angle of the conveyance guide wall 120, the feed speed of the workpiece 15 in the axial direction can be varied. Note that the air nozzle 19 is directed toward the path for sending the workpiece 15.
is arranged. The air nozzle 19 is connected to the compressor 2
0 is the piping 21. 23 is a control device connected to the completion valve 22, and 24 is a discharge conveyor. Others are 1st
This is similar to the embodiment.

In addition, in each of the above embodiments, a plurality of belts 7 were provided, but
A single flat belt may also be used.

〔Effect of the invention〕

The conveyance device of the present invention has the effect of smoothly conveying a cylindrical workpiece by moving it in a fine direction while rotating it.
