The present invention relates to a cylindrical workpiece inspection apparatus for inspecting the diameter, length, magnetism, non-magnetism, etc. of a cylindrical workpiece separated and sent out.
[0002]
[Prior art]
FIG. 8 is a view sequentially showing a schematic image of a series of operations of a columnar workpiece inspection apparatus provided with a conventional columnar workpiece separating and feeding device.
[0003]
(1) As shown in FIG. 8 (a), the leading cylindrical work 8 sliding down the inclined rail 29 is blocked by the primary stopper 30, and in this state, the diameter of the leading work 8 is measured by the diameter measuring sensor. I do.
[0004]
(2) As shown in FIG. 8 (b), after the succeeding work 9 is pressed by the drop-preventing holding pad 31, the primary stopper 30 is released, and the leading work 8 is dropped on the inclined rail 29 to cause the secondary stopper 32. Stop with
[0005]
(3) As shown in FIG. 8 (c), the length of the work itself is directly measured by the length measuring sensor 18 while the leading work 8 is stopped by the secondary stopper 32, and the length is measured, and the magnetic / non-magnetic state is confirmed. The magnetic and non-magnetic properties of the work are confirmed by applying the sensor 14 to the top work 8. At this time, the primary stopper 30 is closed, the fall prevention press pad 31 is released, and the succeeding work 9 is dropped to the position of the primary stopper 30.
[0006]
(4) As shown in FIG. 8D, the magnetic / non-magnetic confirmation sensor 14 is released.
[0007]
(5) As shown in FIG. 8E, the secondary stopper 32 is released, and the leading work 8 is dropped to the conveyor 28. At this time, the work that has been determined to be defective is dropped to the lower portion of the apparatus before the conveyor 28 and discharged by lowering the defective product discharge guide 33.
[0008]
[Problems to be solved by the invention]
In the conventional columnar workpiece separating and feeding device and the columnar workpiece inspection device described above, since the natural fall due to gravity is used as the basic power source of the workpiece feed, it is necessary to incline the entire device. In addition to a very large space, a supply device for sending the work to the inspection device must be provided at a high position, which causes a secondary restriction that maintenance and the like become inconvenient.
[0009]
In addition, it is difficult to set an inclination angle for allowing the workpiece to fall naturally smoothly due to the influence of the size, weight, surface condition, friction, or the like of the workpiece, or the fall prevention holding pad 31 shown in FIG. In addition, it is very difficult to find conditions such as the shape and timing for holding down the succeeding work 9, and there is a problem that the allowable dimensional range of the size of the work to be inspected can be limited only in a narrow range.
[0010]
Further, the end face of the work 8 is directly detected by the length measuring sensor 18 in a state where the leading work 8 is stopped by the secondary stopper 32. In this case, the end face of the work 8 is finished by cutting, for example. Therefore, when the sensor 18 is tilted obliquely, there is a disadvantage that the measurement determination by the sensor 18 itself is difficult and the measured value is difficult to stabilize.
[0011]
Furthermore, since the inspected work falls onto the conveyor 28 while having the energy of natural fall, the work also bounces on the conveyor 28 due to the size and weight of the work, and the posture collapses, and the conveyor belt is damaged. There is a problem of doing.
[0012]
As for the defective product discharge, since the defective product is dropped on the way by escaping the defective product discharge guide 33, it is difficult to specify in what trajectory and where each defective product falls. There is also a problem that it is difficult to confirm.
[0013]
Accordingly, the present invention provides a columnar workpiece separating and feeding device capable of smoothly separating and feeding a continuously connected cylindrical workpiece regardless of its size. Further, the present invention provides a columnar workpiece inspection apparatus using the columnar workpiece separation / delivery device, which can surely inspect and transport the columnar workpiece separated and fed by the columnar workpiece separation / delivery device.

[0028]
As described above, the leading work 8 is separated and fed from the supply work 5 by repeating the operations (a) to (e) of FIGS.
[0029]
In the present invention, the cross section of the cylindrical work is not a perfect circle but an irregular shape such as an ellipse by transporting the work 8 with the work pushing member 3 and the work receiving member 4 sandwiching the leading work 8. Even in this case, the work can be sent out without dancing.
[0030]
Next, a description will be given of an inspection apparatus according to the present invention, which is provided with the columnar workpiece separating and feeding device.
[0031]
FIG. 4 is a perspective view showing a main part of the inspection device of the present invention. Above the separated work guide groove 6 of the inspection line, the leading work 8, the preceding work 21, and the inspected work 22 separated from the subsequent work and sent out to the separated work guide groove 6 are linearly transferred on the separated work guide groove 6. Therefore, a work transfer device 11 that can be moved up and down and traverses is arranged.
[0032]
An elevating cylinder 11c traversing along the inspection line by a traversing cylinder 11b is provided above a frame 11a erected on the machine base. An elevating frame 12 is attached to the downward piston rod of the elevating cylinder 11c along the separation work guide groove 6. The lifting frame 12 traverses together with the lifting cylinder 11c by driving the traversing cylinder 11b, and moves up and down by driving the lifting cylinder 11c.
[0033]
The lifting frame 12 supports a first chuck 15, a second chuck 16, a work holder 20, and a pusher 20 a. The first chuck 15 and the second chuck 16 are driven by chuck cylinders 13a and 13b, respectively, and move forward and backward.
[0034]
In the inspection line, a magnetic / non-magnetic confirmation sensor 14 for confirming magnetic / non-magnetic is embedded in the separation work guide groove 6. The length measuring sensor 18 indirectly measures the length of the slide hole 17 of the measuring section formed by the first chuck 15 and converts it into the length of the work. The diameter is measured when the second chuck 16 is opened by the diameter measurement sensor 19 and the preceding work 21 is released. Each measurement data of the leading workpiece 8 and the preceding workpiece 21 is input to a control device (not shown), and the non-defective / defective workpiece is compared with the product data.
[0035]
Between the inspection line and the conveyer 28 for the non-defective product 22a, a revolving disk 23 for rejecting defective products among the inspected workpieces 22 is disposed.
[0036]
FIG. 5 is a schematic view showing the operation state of the revolving wheel for discharging defective products and the discharge chute of the inspection apparatus in the present embodiment. As shown in FIG. 5A, the inspected work 22 is sent out by the work transfer device 11 onto the groove 23a of the revolving disk 23 for rejecting defective products which can be turned. The grooves 23a may be provided at two or more locations as spares.
[0037]
Here, when the inspected work 22 determined to be defective is in the groove 23a, as shown in FIG. 5B, the swivel 23 rotates 90 degrees, and the inspected work 22 is rejected as a defective 27. Discharge to 24. When the defective product 27 is discharged, the defective product 27 hits the swingable open / close cover 25 attached to the discharge chute 24, and the number of discharged defective products 27 is counted by the open / close confirmation sensor 26 that detects the opening / closing operation of the open / close cover 25. Is done.
[0038]
Next, the operation of the inspection device will be described. 6 and 7 are diagrams showing the procedure of the operation of the inspection device of the present invention.
[0039]
(1) As shown in FIG. 6A, the workpiece is separated and fed by the columnar workpiece separating and feeding device, and the workpiece transfer device 11 stands by on the separated work guide groove 6 with the chucks 15 and 16 opened. .
[0040]
(2) As shown in FIG. 6 (b), when the leading work 8 comes on the separated work guide groove 6, the work transfer device 11 is lowered by the drive of the lifting / lowering cylinder 11c, and is moved onto the separated work guide groove 6. The head work 8, the preceding work 21, and the inspected work 22 are covered.
[0041]
(3) As shown in FIG. 6C, the first work 15 is reliably sandwiched by the first chuck 15 and the preceding work 21 is operated by the second chuck 16 by operating the chuck cylinders 13a and 13b. At this time, the inspected work 22 is pressed according to the size of the work by the work holder 20 which is mounted on the front part of the work transfer device 12 and is vertically movable.
[0042]
(4) As shown in FIG. 7 (d), the work transfer device 11 is advanced by the traversing cylinder 11b, and each of the works 8, 21, 22 is moved along the separated work guide groove 6 in length, diameter, magnetic and While moving straight to the inspection position where the sensors 14, 18, and 19 for nonmagnetic confirmation are provided, the inspected work 22 that has been inspected is sent to the revolving disk 23 for discharging defective products. The inspection data of each of the workpieces 8 and 21 is input to the control device, and the non-defective and defective workpieces are determined.
[0043]
Since the leading work 8 passes over the magnetic / non-magnetic confirmation sensor 14 embedded in the separated work guide groove 6 during the moving process, this inspection is completed without any special movement of the sensor.
[0044]
Further, at the stop position, the length of the slide hole 17 of the measuring section constituted by the first chuck 15 chucking the leading work 8 is indirectly measured by the length measuring sensor 18 (FIG. 4), and Converted to length. Thus, even when the finish of the end face of the work 8 is oblique, the slide hole 17 of the measuring section is vertical, so that the measurement variation by the length measuring sensor 18 itself can be eliminated. In addition, the length measurement data can be stabilized.
[0045]
(5) Open the chucks 15 and 16 as shown in FIG. At this time, when the second chuck 16 is opened and the preceding work 21 is released, the diameter of the preceding work 21 is measured by the diameter measuring sensor 19 (FIG. 4). This is because, when the end face of the preceding work 21 is inclined, a phenomenon such as lifting of the preceding work 21 by chucking occurs, so that the diameter measurement point is prevented from moving and the separated work guide groove 6 is prevented. The upper surface of the preceding work 21 is reliably measured with reference to the lower surface of the preceding work.
[0046]
The non-defective product 22a is sent out from the defective product revolving wheel 23 to the transport conveyor 28 located ahead by the pusher 20a. Defective products are eliminated by rotating the revolving wheel 23 for discharging defective products according to a command from the control device.
[0047]
(6) As shown in FIG. 7 (f), after moving the preceding work 22 to the rejected revolving wheel 23, the work transfer device 11 is moved up by the elevating cylinder 11c and returned to the original position by the traversing cylinder 11b. Return to the standby position.
[0048]
By repeating the above operations (1) to (6), inspection of length, diameter, and magnetic / non-magnetic confirmation is performed while only moving the work straight.
[0049]
【The invention's effect】
According to the present invention, the following effects can be obtained.
[0050]
(1) In the present invention, stop in the horizontal supply work guide the beginning workpiece stopper capable slight backward movement of the head of the cylindrical workpiece come supplied continuously connected-grooves, continuous to the second Applying the pressure of the cylinder from above so that the incoming work cannot move forward, and at the same time pulling the stopper for the top work, the top work is continuously connected and released from the pressing force of the cylindrical work being pushed. You . A work extruding member arranged at right angles to each V-groove to feed the leading cylindrical work one by one from the supply work guide groove to which the work is supplied to the separated work guide groove positioned parallel thereto; The V-shaped block attached to the tip of the work receiving member having a sufficiently weaker thrust than the work pushing member feeds the cylindrical work in a state of being sandwiched therebetween . Therefore, when the end face of the cylindrical work that continuously connects on the horizontal V-groove with a certain amount of pressing pressure is slightly oblique, or the cross-sectional shape is not a perfect circle, but is slightly distorted like an ellipse However, it is possible to smoothly separate and send out individual works.
[0051]
(2) In the present invention, the diameter and length of the cylindrical workpieces, which are individually fed one by one, are moved linearly only on the separated workpiece guide grooves by a workpiece transfer device having lifting, traversing and chucking functions. In addition, since the magnetic and non-magnetic inspections are performed, the volume occupied by the entire apparatus can be reduced, and work such as maintenance can be easily performed.
[0052]
(3) In the present invention, a magnetic / non-magnetic sensor is buried in the detection-side guide groove in which the cylindrical workpiece moves to check the magnetic / non-magnetic properties of the workpiece, so that the sensor has a special operation mechanism. Need not be provided.
[0053]
(4) In the present invention, the length of the cylindrical workpiece is indirectly measured by measuring the displacement of a slide hole formed by the chuck with a sensor when the workpiece is transported while being sandwiched between the chucks of the workpiece transport apparatus. Since the measurement structure is adopted, even when the end face shape of the cylindrical workpiece is finished slightly obliquely, it is possible to eliminate the measurement variation of the sensor itself.
[0054]
(5) In the present invention, by having the work holding mechanism movably attached to the inspection end sending section so as to be vertically movable, it is possible to forcibly disturb the posture of the cylindrical work even in the part of the work transfer device that does not chuck. It is.
[0055]
(6) Immediately after the extension of the separation work guide groove, a revolving disk for rejecting defective products having a groove is provided so as to revolve and reject defective products from the line. Since the number of ejected workpieces is confirmed by pushing the openable cover open and closed by the ejected workpiece, defective products can be ejected faster and more reliably on the line, and the quantity must be confirmed. Becomes possible.
