Description

DETAILED DESCRIPTION OF THE INVENTION 8. Field of Industrial Application The present invention relates to a workpiece unloading device for a gear inspection machine.

b. Conventional technology Conventionally, in order to inspect the gear meshing sound of a workpiece (final gear), which is a gear to be inspected, using a gear inspection machine, for example, the workpiece and a reference gear (mask gear) are aligned horizontally and meshed, and this The distance between gear axes, etc. when the gears are rotated is measured using an electronic micrometer, the output of the electronic micrometer is amplified using an amplifier, and then converted to a digital signal using a digital converter. Abnormalities such as tooth vibration and dents on the workpiece are detected by comparing them with standard values such as dents and dents. Once the inspection by the inspection machine is complete, all the workpieces, including those that have passed, are placed horizontally and transported onto the slat conveyor, or the horizontally placed workpieces are moved at right angles using a manipulator, etc. It is rotated to stand up once, and then placed in a bucket conveyor and carried out.

Problem to be Solved by the C0 Invention However, in the above-described workpiece delivery method, when it is necessary to stock the workpieces on the delivery conveyor, the diameter of the final gear is large, so the workpieces placed horizontally cannot be stocked on the slat conveyor. If they are placed side by side, the overall length of the conveyor becomes long, and there is a drawback that a large installation space for the carrying-out device must be secured. On the other hand, the inspection process for gear meshing noise is the final process of the processing line, and the workpieces are manually placed on pallets after inspection (palletizing), so it is not possible to have workers standing by at the inspection machine all the time. Therefore, it is necessary to have a stock of inspected workpieces.

In addition, a method in which inspected workpieces are handled using a manipulator or the like and transported by a bucket conveyor can shorten the overall length of the conveyor, but this method is not economical because the use of an expensive manipulator increases equipment costs. This is not only disadvantageous, but also increases the time required to carry out the work, making it impossible to improve work efficiency.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a workpiece unloading device for a gear inspection machine that can eliminate the above-mentioned drawbacks.

d. Means for Solving the Problems In order to solve the problems of the prior art described above, the present invention includes an inspection machine body for inspecting a workpiece, which is a gear to be inspected, and an inspection machine body arranged in relation to the inspection machine body. A positioning system comprising: a carry-in conveyor and a bucket conveyor, and a guide member disposed obliquely between these conveyors, and in which the buckets are positioned in a position in which the buckets are erected diagonally upward toward the guide member in a rotating part of the bucket conveyor. Means is provided to drop the workpiece inspected by the inspection machine main body from the carry-in conveyor via the guide member, and slide it into the bucket positioned by the positioning means, and the inspected workpiece is placed in the bucket. I try to transport it in the stored state.

e. Function The workpiece unloading device for a gear inspection machine according to the present invention is provided with positioning means for positioning the bucket of the bucket conveyor for transporting the workpiece, which is the gear to be inspected, to a position that stands diagonally upward toward the guide member. Therefore, it becomes possible to store inspected works placed horizontally in the bucket without using a manipulator or the like.

The loader 3 is for loading (loading, loading, etc.) a work W that has been positioned at a carry-in position and supplied by a carry-in device, which will be described later, into an inspection position, and has a work hand 8 that grips the work W. ing. The work hand 8 is provided with a pair of hand claws 9.9 that are arranged opposite to each other and can be opened and closed. It is formed.

Further, the loader 3 is provided with a turning mechanism 10, and the loader 3 is turned by the turning mechanism 10 within a range of a turning stroke L around a turning shaft 11, so that the work hand 8 can be moved to the loading device and the loading device described later. It is configured to be placed in correspondence with the unloading device.

Further, a carry-in device 12 and a carry-out device 13 are arranged around the inspection machine main body 1 in association with the loader 3.

The carry-in device 12 is installed on the front side of the inspection machine main body 1, and the work W to be inspected is moved up to the carry-in device (and the passing workpiece carry-out position) provided with a stopper 14 that can move up and down.
It conveys at predetermined intervals, and has a driving device 215 and a carry-in slat conveyor 16.

The carry-out device 13 is installed on the side of the inspection machine main body 1, and is used to transport the workpiece W after the inspection to the end opposite to the inspection machine main body 1, and is driven by a drive device 15a.
It is equipped with two unloading conveyors IT, 18.19. In other words, these carry-out conveyors include a bucket conveyor 17 serving as a first carry-out conveyor that conveys the accepted work 4a, a second carry-out slat conveyor 18 that carries the dented rejected work-b, and a dented rejected work-C. It consists of the third unloading slat conveyor 19, and in this order the front side (
They are arranged in parallel from the bottom (in Figure 1). Therefore, the bucket conveyor 17 that conveys the accepted work Ila is arranged on the same plane as the carry-in conveyor 16 with the slide rail 20 in between, and the accepted work-a is stored on the bucket conveyor 17. A plurality of buckets 21 are provided at intervals. Slide rail 2
Reference numeral 0 denotes a guide member that guides the inspected acceptable work-a to the bucket 21, and is arranged so as to be inclined downward toward the rotating portion of the carry-in conveyor 16 and the rebucket conveyor 17.

Further, the rotating part of the bucket conveyor 17 is provided with a positioning means 22 for positioning the bucket 2I, which is conveyed in an empty state with nothing inside, in a position that stands diagonally upward toward the slide rail 20. . The positioning means 22 includes a cylinder 24 attached to a support plate 23 disposed outside the bucket conveyor 17, and the cylinder 24 is provided with a guide rod 25 that is movable forward and backward. At the tip of the guide rod 25,
A fitting hole 27 is formed into which a pin 26 protruding from the side surface of each bucket 21 fits. In addition, in FIGS. 3 and 6, the reference numeral 28 is a photoelectric switch, and this photoelectric switch 28 confirms that the accepted work-a is stored in the bucket 21, and controls the forward and backward movement of the guide rod 25. It has become. Further, the symbol S is a storage space for the bucket 21.

On the other hand, a first jig 29 for installing the workpiece W and a second jig 31 for installing the reference gear 30 are disposed at the inspection position of the inspection machine main body 1. The second jigs 29 and 31 each include a collet ratchet 32, 33 and a rotation center 34, 35 for rotatably holding the workpiece W or the reference gear 30. However, when the workpiece W and the reference gear 30 are rotated in a meshed state at the above-mentioned inspection position, vibrations are generated, and this vibration is detected by a piezoelectric acceleration pickup attached to a bearing box (not shown) and outputted. By processing the signal, it is possible to determine the presence or absence of dents and the magnitude of the whirring sound, and the work W, which is the gear to be inspected, is sorted into acceptable work-a, dent-rejected work-b, and undulating-rejected work-C. It is configured so that it can be

Next, the operation of the workpiece unloading device of the gear inspection machine will be explained.

First, by driving the carry-in conveyor 16 of the carry-in device 12, the workpiece W is transported to the carry-in position and positioned, and at the same time, the loader 3 is moved forward and lowered by the advancing/retreating mechanism 2 to be placed at the carry-in position and positioned. The work W is gripped by the work hand 8. Then, the loader 3 is raised and retreated by the forward/backward moving mechanism 2 to load the work W into the inspection position of the inspection machine main body 1, and the hand claw 9 of the work hand 8 is opened to set the work W into the first jig 29. . The loader 3 waits at the inspection position with the hand claw 9 of the work hand 8 open, and in this state, the work W and the reference gear 30 set on the second jig 31 are meshed and rotated to a predetermined position. Conduct inspections.

The work W after the inspection is immediately gripped by the work hand 8 of the loader 3 which is on standby.

Next, the forward/backward moving mechanism 2 or the turning mechanism IO is driven according to the inspection result, and the loader 3 is moved forward/backward or rotated to sort the work W. That is, when the inspection result is acceptable, the loader 3 moves forward and delivers the accepted workpiece-a to the carry-out position of the carry-in device 12. Along with this, the stopper 14 operates downward and the carry-in conveyor 16 is driven. The passing work Ua slides down on the slide rail 20. During this time, the bucket 21 on the bucket conveyor 17 is moved toward the guide rod 21 by operating the cylinder 24 of the positioning means 22.
The fitting hole 27 of No. 5 and the pin 26 of the bucket 21 fit together,
It is positioned diagonally upward toward the slide rail 20 (see FIGS. 2 and 3). However, the passing workpiece W falling down the slide rail 20
The workpiece a is slid into and stored in the accurately positioned bucket 21, and the accepted workpiece a is reliably delivered. Further, when it is confirmed by the photoelectric switch 28 that the accepted workpiece-a has been placed in the bucket 21, the guide rod 25 retreats into the cylinder 24, the fitting hole 27 comes out of the bin 26, and the positioning state is released. Ru.

Thereafter, the bucket conveyor 17 is driven, and the bucket 21 containing the inspected and passed work-a is conveyed while rising in the direction of the arrow shown in FIG. The bucket conveyor 17 stops after being transported to a predetermined position. Similarly to the above operation, the guide rod 25 moves forward as the cylinder 24 operates, and the fitting hole 27 and pin 26 fit into each other, so that the next bucket 21a is positioned. On the other hand, when the carry-in conveyor I6 sends out the accepted work Ha, it simultaneously conveys the next work Hd to the carry-in position, loads the next work-d into the inspection position of the inspection machine main body 1 according to the above-mentioned procedure, and then carries out the above work. Similar actions are repeated.

If the inspection result is a failure, the loader 3 rotates 180'' clockwise and delivers the failure workpiece to the unloading position of the third unloading slat conveyor 19 (
1), the unloading device 13 is accordingly driven, and the rejected workpiece Hc is transported to a predetermined position by the third unloading slat conveyor 19. In addition, if the inspection result is dent failure, the loader 3 is rotated 180 degrees clockwise.
It rotates and moves forward to deliver the rejected workpieces with dents to the delivery position of the second delivery slat conveyor 18. Along with this, the unloading device 13 is driven, and the rejected workpiece-b with dents is transported to a predetermined position by the second unloading slant conveyor.

Although one embodiment of the present invention has been described above, the present invention is not limited to the embodiment described above, and various modifications and changes can be made based on the technical idea of the present invention.

g. Effects of the Invention As described above, the workpiece unloading device for a gear inspection machine according to the present invention is provided with a positioning means for positioning the bucket of the bucket conveyor for transporting the workpiece to a position standing diagonally upward toward the guide member. By dropping the workpiece inspected by the inspection machine main body via the guide member, the workpiece is slid into the positioned bucket and stored, so that the inspected workpiece placed horizontally can be It can be stored in a bucket and transported without using a manipulator, etc., and it is possible to stock a large number of workpieces even if the overall length of the transport container is shortened.
The space required for the unloading device can be significantly reduced compared to the conventional method. Moreover, since the workpiece unloading device of the present invention does not require the use of expensive manipulators, etc., it is possible to significantly reduce equipment costs, and the time required to unload the workpieces is also shortened, resulting in shorter cycle times and more work. Efficiency can be improved.
