Description

  In the present invention, an annular group such as a transmission belt, a rubber band, and an O-ring is installed on two axes, and the annular group is easily aligned in a line without overlapping, and then the annular group is extruded to disturb the arrangement. The present invention relates to an annular object counting device and an annular object counting method capable of accurately counting the number of annular objects by dropping the annular object in the forefront row from the main shaft without any problem.

  The transmission belt, which is an annular material, is usually bundled by counting a predetermined number of belt belts that have been vulcanized and formed by cutting the belt material at regular intervals. Conventionally, as an annular material counter for performing this counting, a transmission belt is suspended from an annular material holding plate provided above a conveyor belt, and the transmission belt is gradually pushed out, thereby separating the transmission belt from the conveyor belt. The power transmission belt is transported toward the open end by the transport belt. After this, the roller provided with a predetermined gap between it and the conveyor belt is rotated in the opposite direction to the conveyor direction, and if there is an overlap in the transmission belt, the upper transmission belt is retracted by contact with the roller. To remove the overlap. Then, the transmission belt is counted by the detection sensor, and when the predetermined number is counted, the tip of the rod is advanced and brought into contact with the uncounted transmission belt, so that the uncounted transmission belt becomes the counted transmission belt. It is configured to prevent mixing (for example, see Patent Document 1).

Recently, a plurality of annular objects are aligned by suspending them on two shafts whose driven shafts are longer than the main shaft, applying tension, and rotating them, and finally applying tension to the pair of upper and lower shafts. An annular material counting method has also been proposed in which the annular material in the row is extruded, the annular material in the front row is dropped from the main shaft, and the annular material dropped on the annular material collecting rod is detected and counted. (For example, refer to Patent Document 2.)

  However, when the transmission belt is pushed out and dropped onto the conveying belt as in the conventional case, the transmission belt cannot be pushed out depending on characteristics such as rigidity, shape, and friction resistance of the transmission belt. was there. For example, when the transmission belt is installed, the transmission belts overlap each other and the adjacent transmission belts may be in close contact with each other, and there is a problem that it is difficult to move accurately even if the transmission belt is pressed.

  In addition, the annular object group is suspended from the main shaft and the driven shaft, and the main shaft is rotated and aligned while rotating the main shaft. Thereafter, the rotation of the main shaft is stopped, and the annular object group to which the tension is applied is pushed out to extrude the front row of annular objects. In the method in which the ring is dropped from the main shaft, the annular material may not be able to catch up with the main shaft due to poor sliding on the driven shaft, and may remain on the driven shaft. It sometimes occurred.

  Therefore, the present invention aligns the annular objects in a row without overlapping, then extrudes the last row of annular objects to drop the front row of annular elements from the main shaft without disturbing the arrangement of the annular groups, and accurately An object of the present invention is to provide an annular object counting device and an annular object counting method capable of counting the number of annular objects.

In the first invention of the present application, the annular object counting apparatus is configured to send and count the annular objects one by one after aligning the annular objects. In this counting device, the distance between the main shaft and the driven shaft is changed, and the main shaft is rotated to align the annular body group under tension , and then the row of the annular object group is maintained without contacting the driven shaft. An annular alignment portion hanging from the main shaft, a push portion for extruding the annular material group to drop the front row annular material from the main shaft, and detecting the annular material falling from the end of the main shaft, and detecting the annular material based on this signal And a counting mechanism for counting the number of transmissions.

  In this counting device, after the annular body group is aligned under tension, the alignment is maintained in a state where it is hung from the main shaft without contacting the driven shaft, thereby making the annular object independent of the friction coefficient of the driven shaft, Even if the annular object becomes long, it can be smoothly dropped from the main shaft and passed through the sensor to accurately count.

  The second invention of the present application is an annular material counting method in which annular materials are aligned, and then the annular materials are sent and counted one by one. In this counting method, an annular object group is suspended from a main shaft and a driven shaft, tension is applied, one shaft is rotated to align the annular object group, and then the driven shaft is moved in the direction of the main shaft. The group is hung from the main shaft without coming into contact with the driven shaft, the front-row annular object is pushed out and dropped from the main shaft, and the number of the annular objects dropped from the end of the main shaft is counted.

  This method does not depend on the friction coefficient of the driven shaft for the front row annular object, and even if the annular object becomes long, it smoothly falls from the main shaft and passes through the sensor, and accurately counts without erroneous counting. be able to.

  In the annular object aligning device and the annular object aligning method of the present invention, the annular object group is suspended from the main shaft and the driven shaft under a predetermined tension, rotated and aligned, and then suspended from the main shaft in the aligned state to extrude the annular object. As a result, it is possible to smoothly move on the main shaft without depending on the friction coefficient of the driven shaft, drop from the main shaft, pass through the sensor, and accurately count without erroneous counting.

  An annular object counting device and an annular object counting method of this embodiment will be described below with reference to the accompanying drawings. FIG. 1 is a front view of an annular object counting device according to the present invention, and FIG. 2 is a diagram showing a state where the annular object is falling.

The annular object counting device 1 according to the present invention also has a plurality of annular objects such as a toothed belt, a V belt, a flat belt, etc. by suspending a transmission belt between a pair of upper and lower main shafts and a driven shaft to change the distance between the shafts. Annulus alignment unit 2 that applies tension and rotates one of the main shafts to align the annular group, and then hangs on the main axis without contacting the driven shaft while maintaining the row of annular groups, and finally The number of rings sent out is counted based on a signal from a push unit 3 that pushes out the ring in the row and drops the ring in the front row from the main shaft and a detector that detects the ring dropped from the end of the main shaft. And a counting mechanism 4.

  In the annular object aligning portion 2, the drive shaft 11 having a substantially circular cross section that is rotatably fixed to the support column 10 and the driven shaft 12 that is movable and can rotate so that the distance between the shafts 11 can be adjusted. A plurality of annular objects 13 are suspended between them. The rotation of the main shaft 11 is transmitted from the prime mover 14 via the transmission belt 15. A transmission belt 15 is suspended between a pulley 16 attached to the main shaft 11 and a pulley 17 attached to the prime mover 14, and the rotation of the prime mover 14 is transmitted from the transmission belt 15 to the main shaft 11.

  On the other hand, the driven shaft 12 has a substantially circular cross section, and one end thereof is fixed to a guide member 20 fitted to the guide rail 19 and is in a cantilever state. The guide rail 19 is arranged in the longitudinal direction (vertical direction in the figure) on the support column 10. One end of the driven shaft 12 is fixed to the rod 22 of the cylinder 21. When the cylinder 21 operates, the driven shaft 12 moves up and down along the guide rail 19 to adjust the inter-axis distance with the main shaft 11.

  The annular object 13 is suspended from the main shaft 11 and the driven shaft 12 whose distance between the axes is reduced. After the driven shaft 12 is lowered, a tension is applied to the annular object 13 by the cylinder 21 and the main shaft 11 is rotated, so that the annular object 13 is aligned without overlapping or twisting. The tension is 0.1 to 0.85 kg / cm, and the rotation time of the main shaft is 2 to 60 seconds. After the annular objects 13 are aligned, the rotation of the main shaft stops, the cylinder 21 is exhausted, and the tension of only the own weight of the driven shaft 12 is applied. Thus, the counting work is awaited with the tension (0.1 to 0.5 kgf) not to be bent on the annular object 13 while maintaining the aligned state.

Thereafter, before entering the counting operation, in the annular object aligning portion 2 that becomes the hanger portion 5, the driven shaft 12 is brought close to the main shaft 11 to release the tension of the annular material 13 , and the annular material 13 is suspended from the main shaft 11. To. At this time, the rows of the annular group 13 are aligned without being disturbed.

  In the push part 3, as shown in FIG. 1, the push plate 30 fitted to the main shaft 11 can reciprocate along the axial direction of the main shaft 11 by the operation of the cylinder 31. Press the ring 13 in the row. The annular member 13 group is smoothly fed out on the main shaft 11 with little frictional resistance without depending on the friction coefficient of the driven shaft 12 and moves without disturbance of the row, so that the front row of the annular member 13 can be reliably removed from the main shaft 11. Fall into.

The counting mechanism 4 is arranged on the side of the annular object alignment portion 2. The counting mechanism 4 includes an annular collection rod 33 for receiving the front row of annular objects 13 fed from the main shaft 11, a support member 34 supporting the annular collection rod 33, and rotating the support member 34. A turning drive device (not shown) capable of positioning the annular collection rod 33 at an arbitrary turning position is provided. The detection sensor 36 for counting the annular objects 13 dropped one by one on the annular object collecting bar 33 is incorporated in a sensor support bar 37 provided in parallel with the annular object collecting bar 33. . This detection sensor 36 is, for example, a transmission type optical sensor from the light emitting part and the light receiving part, and detects only the tip part (one side) of the moving annular object 13 by light to enable accurate counting. Yes.
Of course, the counting mechanism 4 may not be provided with a turning drive device.

  The length of the driven shaft 12 may be longer than the main shaft 11 by about 1 to 3 mm. Therefore, when the last row of annular objects 13 is pushed out, the foremost row of annular objects 13 surely falls from the short-length main shaft 11 and moves to the annular object collecting rod 33. If the lengths of the main shaft 11 and the driven shaft 12 are set to be the same, the annular object 13 may protrude upward or downward, and its behavior may become unstable.

Hereinafter, a method for aligning the annular objects will be described.
First, as shown in FIG. 2, the ring 13 group is suspended by a main shaft 11 surrounded by a urethane elastomer and a non-rotating metal driven shaft 12 as shown in FIG. After applying a tension that does not bend, the main shaft 11 is rotated at a rotational speed of 100 to 200 rpm, thereby bringing the group of annular members 13 to the main shaft 11 and sliding on the other non-rotating driven shaft 12. Thus, the group of annular members 13 whose alignment is disturbed can be aligned in a row.

  Then, as shown in FIG. 4, the driven shaft 12 is brought close to the main shaft 11, and the annular object 13 group is hung from the main shaft 11 without contacting the driven shaft 12. At this time, the row of the annular group 13 should not be disturbed.

  Subsequently, as shown in FIG. 5, after the tip of the annular object collecting rod 33 is brought close to the tip of the annular object aligning portion 2, the push plate 30 is moved by the operation of the cylinder 31 of the push portion 3 to The front-row annular object 13 is further dropped onto the annular object collecting rod 33 from the main shaft 11 without disturbing the line by extruding 13. The fallen annular body 13 is detected by passing light through only the tip (one side) of the annular object 13 with light by the detection sensor 36 incorporated inside while descending on the inclined annular object collecting rod 33 to accurately count. Counting is performed until the annular body 13 set in the annular object alignment portion 2 is eliminated.

  According to the present invention, a plurality of annular objects such as a formed transmission belt are automatically aligned and can be accurately counted, thereby eliminating the time-consuming counting operation by the operator.
