Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention continuously aligns parts such as screws, rivets, bolts, etc. consisting of heads and legs using a pair of endless belts that move in the same direction and at the same speed. The present invention relates to an apparatus for transporting parts, determining whether the external shape of the parts is within a predetermined value range for each determination item during the transport, and inspecting the parts for good or defective parts based on this data.

[Conventional technology]

As a conventional inspection device for inspecting good and defective parts, there is a Shutrail 10 as shown in Fig. 5.
The screws 102 that are continuously aligned and supplied on the disk 110 are held in the holding grooves 110a formed at predetermined intervals in the continuously rotating disk 110,
The determination unit 130 determines various factors such as the leg length of the screw 102 placed on the rotation trajectory of the screw 0a, the plating of the screw 102, the quality of the thread shape, and the quality of the head shape of the screw 102. There is a device that determines whether a good product is a defective product and removes the defective product using air from a nozzle 133.

[Problem that the invention seeks to solve]

However, since the parts that are continuously supplied on the shoot rail must be transported at predetermined intervals, it takes time to inspect a large number of parts, making it impossible to efficiently judge the parts. In addition, in recent years, there has been a demand for the ability to determine whether a large number of parts are good or defective in a short period of time due to increased speed of manufacturing equipment.
Due to its structural limitations, there was a lot of backlog during the sorting process. Furthermore, in this device, even if as many holding grooves as possible are formed on the disk to cope with the large amount of sorting work, the capacity of the storage device for storing judgment signals from the judgment unit is required to be equal to the number of holding grooves. Therefore, there were problems such as high cost.

In addition to this, there is also a leg length sorting device for headed rod-shaped parts described in Japanese Utility Model Publication No. 59-2870. This is to detect whether the length of the leg is a predetermined length for a screw that passes on an inclined shoot rail with the head at the top and the leg at the bottom. However, as the screws flow on this shoot rail, they wobble or move at a slight incline during the flow motion, making it impossible to accurately test the leg length. There is a problem that additional processing is required and adjustment becomes complicated.

Furthermore, Japanese Utility Model Application Publication No. 170506/1983 discloses a device that supports a head and sends a component having a head and legs forward. In this method, an endless strip with a circular cross section is placed parallel to the drive pulley and the driven pulley with a space between them, and the head is placed between them for conveyance. Items with relatively large heads are transported in a line, but screws with relatively small heads may be transported diagonally or if there is even a slight gap between the screws. There are also problems such as falling and the inability to use it as an inspection device for defective products.

The present invention solves these problems and provides a completely new endless belt transfer device that has a simple structure and is provided in response to the needs of the times to reliably and accurately judge a large number of parts while transferring them.
During this transfer, various judgments are made by the judgment unit.
The first object of the present invention is to provide an apparatus for determining whether parts are good or defective based on these results.

The second objective, in addition to the first objective, is to periodically interrupt the supply of parts to the endless belt, during which time the number of parts transferred on the belt and the number of data detected during the transfer are To provide a device for inspecting non-defective parts and defective parts, which is configured to determine whether they match or not, and to determine whether the parts are correctly classified as non-defective or defective.

In addition to the first purpose, the third purpose is to identify non-defective parts and defective parts due to lack of part data while the parts are being transported by an endless belt, when the parts are transported at relatively long intervals. An object of the present invention is to obtain a device for inspecting non-defective parts and defective parts, which is configured to detect abnormalities in the inspection of parts.

[Effect]

When parts are continuously fed in alignment on the shoot rail 1, at the tip of the shoot rail 1, the parts are continuously fed to a pair of endless belts 10 whose transfer path side is moving forward at the same speed. Ru. The parts thus supplied are transported forward with their seating surfaces supported by the pair of left and right endless belts 10. On the other hand, when a component is detected by the component presence/absence detection means 40 arranged along the endless belt 10 on the transfer path side during this transfer,
Based on this signal, a judgment unit 30 placed close to this determines whether or not the value of a preset judgment item regarding the external shape of this part is within the range of set values, and this data is The data is stored in the memory circuit 34. Further, this part is subsequently transferred, detected by the next presence/absence detection means 40, judged by the next judgment unit 30 for another judgment item, and the above operation is repeated. In this way, the judgment signals of the preset judgment items are stored in the respective storage circuits 34 in accordance with the order in which the parts passed, so that when the parts reach the end of the transfer, a signal is input from the arrival detection means 41. Then, the pass/fail judgment control circuit 37 determines whether the part is good or bad, and the signal is sent to the exclusion unit operation circuit 38, which operates to determine whether each successive part is good or bad. Select good products.

Moreover, in addition to continuously sorting parts into good and defective parts by such an action, the supply of parts to the endless belt 10 is periodically cut off.
In the second invention, which is provided with a configuration for determining whether the number of parts matches the number of data necessary for sorting out good and defective parts during this period, inspection of good parts and defective parts is carried out periodically. Interrupting the test and checking the number of data and the number of parts has the effect of increasing the accuracy of the inspection work.

Furthermore, in addition to continuously sorting the parts of the first invention into good and defective parts, when the parts are transferred at relatively intervals, the parts are transferred to the endless belt 1.
By detecting inspection failures due to insufficient data on parts while they are being transferred at zero, inspection abnormalities can be immediately discovered.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. In Figures 1 and 2, 1
is placed almost horizontally, and screw 2 is caused by continuous slight vibration.
A pair of left and right belt-shaped endless belts 10 made of ribbon steel are disposed at the tip of the shoot rail 1 and are arranged at the same distance as the shoot rail 1. Both ends of the endless belt 10 are wound around first and second belt pulleys 11 and 12, respectively, so that they always circulate in parallel. Further, on the side where the endless belt 10 on the non-transfer path side enters the first belt pulley 11, a guide roller 22 for preventing the belt 10 from moving outward by more than a predetermined amount is rotatably attached to a support member 21.
The support member 21 is integrally fixed to a fixing member 13 fixed to the first guide frame 3 which rotatably supports the first belt pulley 11. At the tip of this fixing member 13 is a first tension pulley 16 that applies tension to the belt 10.
is rotatably supported. Also, the other second
A second tension pulley 17 that applies tension to the endless belt 10 on the non-transfer path side is also rotatably supported at a position close to the belt pulley 12 via a fixing member 14, and these first tension pulleys 16
A third tension pulley 18 that applies tension to the belt 10 in the opposite direction to the first and second tension pulleys 16 and 17 is rotatably attached to the fixed member 15 between the third tension pulley 17 and the second tension pulley 17. Supported. On the other hand, a rotating shaft 6 is fixed to the second belt pulley 12, which is fixed to a second guide frame 4 that rotatably supports the second belt pulley 12, and is rotationally driven by a speed-adjustable motor 5. Further, the endless belt 10 on the transfer path side is configured to move along a pair of guide rails 8 whose both ends are fixed to the first guide frame 3 and the second guide frame 4.

Further, on the transfer path side of this circularly moving endless belt 10, that is, on the side where the screws 2 are transferred forward, a device is approached to judge whether the external shape of the screws 2 transferred by the belt 10 is good or bad. A plurality of types of determination units 30, such as a leg length determination unit for determining the leg length of the screw 2, a plating quality determination unit, a screw thread failure determination unit, etc., are arranged at predetermined intervals. As shown in FIG. 3, each of these determination units 30 is connected to a storage circuit 34 for storing signals from these determination units 30. These memory circuits 34 are connected to a quality determination control circuit 37 that determines whether the screw 2 is a good product or a defective product when all the determination signals are input from the respective memory circuits 34. On the other hand, data count circuits 35 are branch-connected to the judgment unit 30, respectively.
This data count circuit 35 extracts the signals from each data count circuit 35 and sends them to a data shortage determination circuit 36 which compares the signals to determine whether there is as much data as the number of determination units 30, that is, whether there is a shortage of data. It is connected. Further, this data count circuit 35 is branch-connected to an arrival detection means 41 disposed at the end of the transfer path, and this arrival detection means 41 causes the data count circuit 35 to
The arrival detection means 41 detects that the screw 2 has reached the end of the transfer, and the data count circuit 35 outputs the determination item for the screw 2. It outputs a signal for retrieving pass/fail data stored in order for each test.

In addition, in this inspection device, the supply of continuous screws 2 to the endless belt 10 is periodically stopped, and it is checked whether the number of data of all judgment items corresponds to the number of screws. Due to the necessity of inspection, the shoot rail 1, which vibrates continuously, is provided with a timer (not shown) for stopping the slight vibrations in time. This timer is preset with a time sufficient for the screw 2 on the endless belt 10 to completely disappear from the end of the transfer, and a confirmation means 60 is activated by a signal from the timer after the set time has elapsed. It is connected. This confirmation means 60 is connected to each data count circuit 35.
This data counting circuit 35 is connected to a data presence/absence detection circuit 61 which determines that when a screw is not on the endless belt 10, no data is normal and data is abnormal. This data presence/absence detection circuit 61 is connected to output an operation start signal to the shuttle rail 10 when it is determined that the data presence/absence detection circuit 61 is normal.

Furthermore, as shown in FIG. 4, the memory circuit 34 has a data table 50 that stores data for each determination item, and the data for screw 2 is stored in order from address 1 of this data table 50. It's getting old. This data table 50 has at least the number of addresses corresponding to the number of screws lined up on the transfer path for transporting the screws 2, and the first stored data (A-1),
(B-1) and (C-1) respectively in the data table 50
They are now being taken out all at once.

Although there are various other types of determination units 30, the number of determination units 30 may be increased or decreased as appropriate depending on the necessary determination items. Moreover, presence/absence detection means 40 for detecting whether or not the screw 2 is inserted into these judgment units 30 is installed on the entrance side of each of these judgment units 30, and when a signal from this presence/absence detection means 40 is input, The determination unit 30 is adapted to operate. Furthermore, the arrival detection means 4
1 and the presence/absence detection means 40 are not shown, but are photoelectric sensors or other sensors comprising a light projector and a light receiver. Furthermore, in this embodiment, the supply of screws 2 is periodically stopped by stopping the slight vibration of the shoot rail 1, but instead of this, a shutter (not shown) is installed at the end of the shoot rail 1. Screw 2
It may also be possible to prevent the supply of Furthermore, although a timer is provided as a means for periodically stopping the supply of screws 2, instead of this, the supply may be periodically stopped depending on the amount or number of screws 2 to be supplied.

Furthermore, as shown in FIG. 1, the presence/absence detection means 40 includes a guide attached to the side wound around the first belt pulley 11 to prevent the pair of endless belts 10 from moving away from each other by more than a predetermined amount. Blocking means (not shown) that functions similarly to roller 22
is installed. If even one of the various judgment items determined by the judgment unit 30 does not fall within the set value range, a signal from the pass/fail judgment control circuit 37 is applied to the terminal end of the screw 2 on the transfer path side. A defective product exclusion unit for eliminating screws 2 is arranged. In this embodiment, as this defective product removal unit, a nozzle 33 is attached to the second guide frame 4, which supplies pressurized air to remove the defective screw 2 only when it is determined to be a defective product.

Next, the operation of this embodiment will be explained. As shown in Fig. 1, when the screws 2 are continuously aligned and fed on the shoot rail 1 with their heads up and their legs hanging down, a pair of endless belts that have already started to move 10, the screw 2 is moved while maintaining this posture. As a result, the head seat of the screw 2 is supported by the endless belt 10, and the screw 2 is transported forward.
During the transportation of the screw 2, a determination unit 30 such as a leg length determination unit for the screw 2, a plating quality determination unit, a screw thread defect determination unit, etc. is paired with the presence/absence detection means 40 along the belt 10 on the transport path side. Since the screws 2 are arranged in sequence, the screws 2 pass through these determining units 30 one after another, and each determining unit 30 determines whether the screws are good or bad. When the screw 2 passes, this pass/fail judgment data is sequentially stored in the memory circuit 34 and entered into the respective data tables 50. In this way, the data passed through all the judgment units 30 one after another and extracted for each judgment item is stored in the respective data count circuits 35 and storage circuits 34 in the order in which the screws 2 pass, and is stored in the data table 50. Therefore, when the first screw 2 is detected by the arrival detection means 41, a data presence signal is input from the data count circuit 35 due to this signal, and the data corresponding to this screw 2 is input from the data table 50 of all the storage circuits 34. are taken out for each determination item, and the quality determination control circuit 37 determines whether the products are good or defective. On the other hand, the next data is entered after this extracted data, and the data are carried forward in order. Therefore, the memory circuit 3
4 requires less storage capacity.

Then, the signal enters the rejection unit operation circuit 38 from the pass/fail determination control circuit 37, and operates according to whether the product is good or defective. For example, if all the determination units 30 determine that the screw is a good product, no compressed air is supplied from the nozzle 33 and the screw 2 is discharged as a good product. On the other hand, if any one of these determining units 30 determines that the screw 2 is defective, the screw 2 is determined to be defective, and pressurized air is supplied from the nozzle 33 to blow the screw 2 forward.

Further, when the screw 2 is transported at a relatively long interval during or near the end of the inspection, and the screw 2 reaches the arrival detection means 41 after the determination unit 30 performs the determination operation,
It is determined from each data count circuit 35 whether all data for each item corresponding to this screw is present or insufficient. As a result, if all the data is present, the data is taken out from all the storage circuits 34, and a determination is made as to whether the product is good or defective.
On the other hand, if there is insufficient data due to reasons such as the screw 2 being transported lying down on the endless belt 10 instead of in its normal position with the head up and the legs hanging down, The judgment becomes abnormal and the inspection device stops.

In addition, when determining whether or not the screws 2 that have been continuously supplied have been successfully inspected up to now, the supply of the screws 2 from the shoot rail 10 is periodically stopped and the screws 2 are endless. When the signal from the confirmation means 60 is input after all the data have been completely transferred by the belt 10, the data count circuit 35 outputs the respective signals. This signal is sent to the data presence/absence detection circuit 6.
If it is determined that all the data is missing in step 1, it means that screw 2 has been successfully inspected, and the next screw 2 is inspected again.
supply to the endless belt 10 is started. on the other hand,
At this time, if it is determined that the data is present, it means that the data has been duplicated for some reason, and the screw inspection performed during this time is determined to be abnormal.
The inspection equipment remains stopped.

In this embodiment, the screws 2 are continuously aligned and fed forward by applying slight vibrations to the shoot rail 1, but instead of this, an inclined shoot rail is used to allow the screws 2 to slide down under their own weight. It may also be configured such that it is transferred between the endless belts 10. Further, in this embodiment, ribbon steel is used as the endless belt 10, but it is not limited to this in any way, and any belt-like material that is thin and has tensile strength may be used. Furthermore, in this example,
Previously, the supply of screws 2 was periodically stopped for a predetermined amount or for a predetermined period of time, and during this period it was checked whether any data remained in the data table 50 of the memory circuit 34. screw 2
The inspection may be performed continuously until the inspection is completed, and by doing so, the inspection time is shortened.

〔Effect of the invention〕

As is clear from the embodiments described above, the present invention is directed to a component consisting of a head and legs, with the head facing upward, the head seat supported, and the legs hanging in the same direction. A pair of band-shaped endless belts 10 that can be circulated at the same speed are installed parallel to each other and spaced apart enough to fit the legs, and the endless belts are driven by a speed-adjustable motor 5.
A plurality of pairs of component presence/absence detection means 40 and determination units 30 operated by the output signal of the presence/absence detection means 40 are arranged in contact with each other on the transfer path side, and a storage circuit stores the signals in all of these determination units 30. 34 respectively, and the endless belt 10
The determination unit 30 detects the arrival of the parts for which data has been collected for each determination item at the transfer end on the transfer path side, and each memory circuit 34 stores the data.
A component arrival detection means 41 is disposed for outputting a signal for retrieving data corresponding to the component from the component.
If the data from all the judgment units 30 corresponding to this part in all the storage circuits 34 and the arrival detection means 34 are within the preset value range, it is judged as a good product, and if there is any other data than this, it is judged as a good product. A quality determination control circuit 37 is connected thereto to output a signal indicating a defective product.

In this way, the part is transported by supporting the head seat surface of the part with the belt-shaped endless belt arranged in parallel, so that the part does not fall, wobble, or tilt during transport, and is always on its feet. Since the parts can be transported with the parts facing down, the parts can be inspected accurately, and in particular, parts with a small difference between non-defective and defective parts can be inspected stably and accurately.
Furthermore, since this belt-shaped endless belt is driven by a motor whose speed can be changed and adjusted, the transport speed of the parts can be easily adjusted in accordance with the processing speed of various detection means and the determination unit, making it easy to use. Further, since various determination units can be freely arranged near the bottom surface of the endless belt, space can be used efficiently and the inspection device can be easily maintained and managed.
Furthermore, since the quality of parts can be determined for each judgment item while the parts are being continuously aligned and transferred, it is possible to efficiently determine whether all parts are good or bad in a relatively short time when inspecting a large number of parts. Furthermore, by increasing the speed of manufacturing equipment, it is possible to sufficiently respond to requests for determining whether a large number of parts are good or defective in a short time, and the backlog of parts can be eliminated. Furthermore, in this device, once the judgment unit has finished determining whether the part is good or bad, the next data is moved up to the address of the data table where this data was stored, so the storage capacity is relatively small. The amount required is small, and the device can be provided at low cost. Furthermore, it is possible to realize a device that has already been developed in response to the demands of the era of high speed, which performs various judgments during transportation using a judgment unit to judge whether parts are good or bad. Further, by periodically stopping the supply of parts and determining whether the inspection during this period is normal or not, the reliability of this inspection work is increased and the quality is improved. Furthermore, while parts are being transferred at intervals, it is possible to immediately determine whether the inspection of the part is normal or abnormal, and the response to this can be quickly taken, thereby preventing the introduction of defective products. A unique effect can be obtained.

1 is connected, and when the data detection circuit 61 outputs a signal indicating that there is no data, the supply of parts to the endless belt 10 is restarted, and when a signal indicating that there is remaining data is output, the supply of parts to the endless belt 10 is restarted. A device for inspecting non-defective parts and defective parts, characterized in that the supply of parts is stopped. 4 A pair of belt-shaped endless belts that can circulate in the same direction and at the same speed with the head of a component consisting of a head and legs facing upward, supporting the head seat and hanging the legs. 10 are installed parallel to each other and with an interval that allows the legs to fit together, and a speed-adjustable motor 5 is attached to either one of the first and second belt pulleys 11 and 12 around which the endless belt 10 is wound. A plurality of pairs of component presence/absence detection means 40 and judgment units 30 which act based on the output signals of the presence/absence detection means 40 are arranged in contact with each other on the transfer path side of the endless belt 10, and all of these judgment units 30 are connected to each other. A memory circuit 34 for storing the signal and a data count circuit 35 for counting the number of the signal are connected, respectively, and the judgment unit 30 stores data for each judgment item at the end of the transfer path on the transfer path side of the endless belt 10. Arrival detection means 41 is arranged to detect the arrival of the collected parts and to output a signal from the data count circuit 35 to detect whether data remains in all the storage circuits 34, A signal from the arrival detection means 41 acts on the data count circuit 35 and the arrival detection means 41, and a signal indicating that there is no remaining data causes the supply of parts to be stopped, and a signal indicating that there is remaining data causes all of the storage circuits 34 to be When data is extracted from all judgment units 30 corresponding to this part and the data is within a preset value range, a good product is output, and if there is any other data, a defective product signal is output. A device for inspecting non-defective parts and defective parts, characterized in that a quality determination control circuit 37 is connected.
