Inspection apparatus for inspecting articles moving on a conveyor

[Detailed Description of the Invention]

The present invention relates to the inspection device for inspecting the article which moves in a conveyor top, and it is in a concrete target, When an article moves in a conveyor top, each article can be scanned from two almost perpendicular directions, and two output signals can be emitted, The scanning means [ each / of respectively the signal / like ] proportional to the quantity of the appearance of inclination of the article from the vertical plane of the scanning direction to carry out, A processing means by which the inclination signal which raises two output signals to the power of two, adds these, and shows a true quantity of inclination from the vertical plane of an article by that cause can be taken out, The comparison means which can emit a removal signal when an inclination signal can be compared with the beforehand selected standard and the inclination signal is over this standard, When it is arranged downstream from the above-mentioned scanning means and a removal signal is received from the above-mentioned comparison means, it is related with an inspection device which includes the elimination means which operates so that an article may be removed from a conveyor. It is determined whether the just manufactured glass container is placed by the conveyor which carries them to an inspection device as usual, this inspection device inspects these containers, and they conform to a standard. Such an inspection device includes a means to investigate the leak of a detection means to, detect whether the container leans from the vertical plane more than the maximum permissible dose for example, the optical means which inspects a container optically, a means to count the size of the difference mouth of the head of a container, and a container. A conventional means to detect such inclination includes mutually the scanning means which can scan each container from two perpendicular directions, when a container moves a conveyor. And a processing means calculates the signal which shows inclination of a container from the output signal of a scanning means, A comparison means measures the predetermined standard showing the maximal permissible dose of this signal and inclination, and when it is over this standard, an elimination means removes a container from a conveyor, before reaching the remaining portion of an inspection device. Such a scanning means and the instrument relevant to it are indicated to the British patent No. 1383962. An inclination detecting means including an elimination means is arranged upstream of other portions of an inspection device. By this, a leaning container does damage to other portions of them, or it is carrying out as [ make / it / not to move ]. The container removed by the inclination detecting means is stopped by various places (station) where an inspection is conducted. A deer is carried out, the second elimination means is connected with the remaining portion of the inspection device, and a failure and a Noodle container are removed to an inspection. An above-mentioned inspection device may include the reading means which reads the seal (marking) on the container in which which model (mold) is it and it is shown whether the container was made. It is because the manufactured goods from many models are usually sent to the same inspection device. if it does in this way -- some examinations with a specific container from a certain specific model -- a failure and Noodle -- reform disposal can be devised by detecting things and changing the conditions of a model or a model. However, in such a device, the container removed by the inclination detecting means cannot detect whether it is Oh by a failure to either of the remaining examinations. A reading means is usually connected with an optical means. Therefore, since it is placed downstream from an inclination detecting means, it is not recorded with which model a container removed by an inclination detecting means was made. Then, the object of the present invention is to provide an inspection device which also records many information about a leaning article suddenly. The present invention supplies the inspection device for inspecting the article which moves a conveyor, and is a device of this present invention, While the article is moving in the conveyor top, each article can be scanned from two mutual almost perpendicular directions, The scanning means which can emit two output signals which are proportional to the quantity of the appearance of inclination from the vertical plane in the scanning direction of an article, respectively, and the two above-mentioned output signals are raised to the power of two, they are added mutually, and it is it, The processing means which can emit the inclination signal which shows a true quantity of inclination from the vertical plane of an article, The comparison means which can emit a refusal signal when an inclination signal can be compared with a predetermined standard and the inclination signal is over this standard, It is placed downstream from the above-mentioned scanning means, a refusal signal (removal signal) is received from the comparison means, and he is I got it. et al., It is an inspection device including the elimination means to which an article can be moved from a conveyor, and is Then, the above-mentioned comparison means inclines with the above-mentioned standard, and compares a signal -- in addition, when it can incline with the second predetermined standard lower than the above-mentioned standard, and a signal can be compared and an inclination signal exceeds the second standard, it is characterized by the point that an indication signal can be taken out. In the inspection device of the present invention which has such a feature, there are two standards about inclination and the number of the articles which cannot pass each standard may be recorded. It becomes possible to acquire more information from this further about the leaning article which should be recorded. For example, it inclines, before inclination must set aside a very vicious intermediary article, and warning is given to a tendency, as a result, the right time is good, and an indication signal can be used so that reform measures can be taken. Or the thing for which the maximum capacity of inclination when the maximal permissible dose of inclination which avoids damage or disturbance shall be shown as the first standard and the article conforms to a standard as the second standard shall be shown, The article among both standards can acquire the information about whether it is a failure to either of the examinations of others of an inspection device. Such an advantage arranges the second elimination means that operates so that the removal signal for removing an article from a conveyor downstream from the first elimination means may be received, The indication signal by a comparison means generates a removal signal, and it is obtained by receiving the removal signal by the second above-mentioned elimination means. Thus, in the device of the present invention, information can be acquired from a plurality of inspection positions (inspection station) placed between two elimination means. If the inspection device includes the reading means which operates so that marking on the article in which it is shown with which model the article was made may be read, the information about in which model the article among both standards originates can be acquired. Two elimination means are used, and if an indication signal is given when a comparison means inclines with the third predetermined standard lower than the second standard, compares a signal and exceeds this third standard, an article is inclining this signal and it can use it as a warning that reform measures should be taken. Since the device of the present invention records with which model the article was made about each article beyond a standard, its recording device is advantageous also in the point which can pursue the manufacturing defect of such a specific model. Next, I will perform detailed description of the inspection device which is one example of the present invention, referring to an accompanying drawing. It must be understood that it is not for having chosen the inspection device of illustration for the description as an example, and limiting an invention. The inspection device shown in a figure is an inspection device for inspecting glass container C which is moving in article, especially conveyor 10 top. Including conveyor belt 12, this belt moves a plurality of containers C to support face 14, conveyor 10 is moved to this support face by container C of Gradually plurality with carriage 16 of conveyor 10, and this carriage carries out time intermediary movement of the path (passage) near support face 14. A plurality of containers C move to another conveyor belt 17 of conveyor 10 from support face 14. Carriage 16 collects a plurality of containers C from conveyor belt 16, lets them slide in those support faces 14 at the inspection place (inspection station) of four Along, and is stopped temporarily because of an inspection by each container at each station. Conveyor 10 contains two spacers 20 which operate a plurality of containers C again in order to maintain a fixed interval mutual. Including scanning means 22 on which the tester implement of the example was placed under the first spacer 20, the scanning means operates so that each container C may be scanned to the direction of a motion of container C from two mutual almost perpendicular directions which are 45 degrees and 135 degrees. Scanning means 22 scans a plurality of containers C, when a plurality of containers C move conveyor belt 12. Scanning means 22 contains two light receivers 26 stationed so that the light from two light emitters 24 and emitters 24 may be received. Scanning means 22 takes out two output signals to line 28. The output signal is proportional to the quantity on the appearance to which container C to be scanned leans from the vertical plane in the scanning direction between emitter 24 and receiver 26, respectively. More detailed explanation of an operation principle and the structure of scanning means 22 are included in the above-mentioned British patent 1383962nd. The inspection device shown in a figure includes similarly processing means 30 which is described in detail by the British patent 1383962nd. From scanning means 22, processing means 30 receives the signal on line 28, raises two output signals to the power of two, adds these things raised to the power of two, and it operates so that the inclination signal which shows a true quantity of inclination from the vertical plane of container C by it may be emitted on line 32. The standard as which the first by which an inclination signal is further supplied to the example of an inspection device from memory storage 36 was chosen beforehand, Comparison means 34 to operate so that it may compare with the standard as which the second supplied from memory storage 38 was chosen beforehand, and the standard as which the third supplied from memory storage 38 was chosen beforehand is included. The first standard is chosen in order to show the maximal permissible dose of the inclination which can avoid the damage over an inspection device, or the disturbance to the device. Therefore, the first standard is set up equally to the square of the maximal permissible dose of inclination. The second standard is chosen in order to show the maximal permissible dose of inclination that container C suits a standard. Therefore, the standard as which the second was chosen beforehand is lower than the first standard set up equally to the square of the maximal permissible dose of inclination. The standard as which the third was chosen beforehand is lower than the second standard. When an inclination signal exceeds the first standard, comparison means 34 sends removal signal sending to line 42, and sends a signal to computer 46 as shown in a figure further also at the other line 44. If elimination means 48 is in the side of conveyor belt 12 of the lower stream of scanning means 48 and the removal signal on line 42 is received, By intersecting conveyor belt 12 and lengthening a plunger, container C is moved from a conveyor belt, container C is put in a caret shot, and it removes from a conveyor belt. The inspection device shown in a figure also contains again a plurality of inspection devices 52 placed on a plurality of inspection stations. These devices 52 are protected from damage and disturbance with container C which the first removed and leans too much by work of means 48. A plurality of devices 52 are connected to computer 46 by line 54, and when it is a failure, a signal is sent to the examination by which container C is carried out by device 52 always at computer 46. Device 52 of the lowest style has marking reading which shows with which model the container on container C was made again, and a reading means which operates so that a marking signal may be transmitted to computer 46 through line 56. If container C is not over the first standard, the container will move to a plurality of stations 18, in order to undergo an inspection further. However, as mentioned above, comparison means 34 operates so that an inclination signal may be compared with the second standard, and when an inclination signal exceeds the second standard, an indication signal is taken out on line 58 which leads to computer 46. The inspection device shown in a figure includes the second elimination means 60 placed on a plurality of inspection stations 18 and the lower stream of the first elimination means 48 again. If computer 46 receives an indication signal on line 58 after passing through the time of a suitable interval, a removal signal will be sent to line 62, or if a removal signal is received from this computer 46 on line 62, elimination means 60 will operate so that container C may be removed from conveyor 10. By intersecting conveyor belt 17 and lengthening a plunger, elimination means 60 removes a container, puts container C in caret shot 64, and removes it from a conveyor. Similarly, if computer 46 is a failure, it will send a removal signal to either of the examinations by which container C is carried out with device 52 through line 62 at the second elimination means 60. When container C does not exceed the second standard, if container C is not a failure, it will not be removed by either of the examinations carried out by device 52. However, if the inclination exceeds the third standard, comparison means 34 will send an indication signal to computer 46 through line 66. Computer 46 has the information and correlation which are received through lines 44, 54, 58, and 66. As far as inclination is related with container C exceeding the first standard, computer 46 can only record the number only removed for this reason. However, about container C which does not exceed the first standard although the second standard is exceeded, it is recorded whether it is a failure on one of the examinations by which computer 46 records the model with which those containers originate, and they are carried out by device 52. About container C which does not exceed the first and the second standard although the third standard is exceeded, through line 68, computer 46 takes out an alarm signal to warning device 70, and gives the warning about the disposition that it inclines to it. This alarm signal includes authorization of the model with which container C originates. It records which standard computer 46 recorded the inclination signal which does in this way and exceeds either the second or the third standard for a start, and it was made with which model about each article exceeding the second or the third standard, and was exceeded. Computer 46 is connected with Memory device 72 with which the recorded information is saved. Memory storage 72 is connected to display unit 74 and print-out device 76. Thus, the inspection device of the present invention which is illustrated to a figure records more information about a leaning container. On the other hand, it was only removed in the conventional device, without detecting with [ especially ] which model such a container was made without moving to a device like 52.
