Definitions

  • the present invention has for its chief object the provision of a method and apparatus for detecting the presence of such needles, as well as other surface imperfections of containers, and the initiation of a signal which will enable a defective container to be manually or automatically removed from a production line for discardment or reprocessing.
  • Another object is to provide a method and apparatus which enables the testing of a container, at one and the same time, for the presence of the aforesaid needles as well as deviations of dimensions of the container from predetermined and pre-set standards, and which in response to the presence of imperfections affords a positive signal which may be utilized to discard the defective container.
  • Another object is to provide an apparatus which while relatively simple, provides a reliable and positive signal in the case of a defective container only.
  • the invention comprehends a rigid plunger or base together with means for introducing it through the mouth of the container and into contact with the bottom or other surface areathereof.
  • the bottom surface of the plunger is shaped to normally contact the interior bottom surface of the container and which, in the absence of defects or distortions in shape, fits closely into surface contact with the container.
  • the plunger or base carries a plurality of feelers slidable in uniformly-spaced apertures therein. These feelers are normally spring-urged outwardly of the gaging surface of the base, so that when the base is urged' into full area contact with the corresponding surface of the container, the feelers are displaced inwardly with respect to the'base; and a signal, or absence of a signal makes it known that the container is normal and usable.
  • the base is prevented from full area contact with the container, the feelers are not fully displaced and another, or different kind of signal is produced indicating that the container is defective and should be discarded or returned for reprocessing.
  • the invention thus enables, not only the detection of needles, but also other roughness or irregularities and 3,355,811 Patented Dec. 5, i967 surface defects in containers. It also enables the detection of discrete foreign objects which may be therein.
  • the invention enables the detection and control of other imperfections because, when the container does not conform to pre-set shape, standards, or dimensions as, for example, excessive thickness, surface deformations, etc., the plunger is stopped short of full normal descent and a corresponding signal is obtained.
  • FIGURE 1 shows a container having an internal defect in the form of one of the aforesaid needles
  • FIGURE 2 is a vertical axial section showing schematic-ally the assembled instrument
  • FIGURE 3 depicts to a scale enlarged over that of FIGURE 2, a portion of the plunger and one of the feelers carried thereby;
  • FIGURE 4 is a simplified diagram showing the circuit connections of the feelers.
  • FIGURE 5 is a diagram showing a circuit for controlling and operating the tester.
  • FIGURE 1 shows by way of example one type of container to be tested for defects and having therein, as indicated at l, a needle or sliver which renders the container objectionable and subject to discard.
  • the dimensions A, B, C and D, indicated upon this figure are among those which the instrument is capable of gaging or testing in addition to its function of detecting imperfections in the bottom wall of the container.
  • the plunger includes a rigid base 2 which is adapted to be inserted into the container or receptacle. This base is fixed to the lower end of a central vertical stem 3. A portion of the frame of the instrument is indicated at 6a and has a bushing 6 with aperture shaped to receive a slide 4 for a smooth guided vertical reciprocation therein. The lower end of the slide is apertured to receive the headed upper end of stem 3. A coil spring 5 within the aperture, bears against the head of the stem and urges it downwardly to the limiting position shown upon FIGURE 2.
  • the upper end of slide 4 is slotted to receive the lower end of a pitman 8.
  • a pivot pin 3a passes through aligned bearing openings in the slotted portion of the slide and the pitman.
  • the upper end of the pitman is pivoted at 811 to a crank 7 fixed with shaft 7a journaled in bearings not shown.
  • body 2 is shown to have a shape and size, in plan, which enables it to pass freely into container 9 to be tested.
  • This body may be of synthetic plastic material.
  • its lower surface is shaped complementary to the inner surface of the base of the jar, container or receptacle 9, so that when the base of the container has no needles or other surface imperfections such as would require it to be discarded, body 2 may descend into full surface contact with the container.
  • Body 2 carries a number of feelers 13 which may be alike and similarly mounted. As shown, feeler 13 fits a vertical bore in and adjacent the periphery of base 2.
  • the bore is counterbored to accommodate a coil spring 14 which abuts at its top against a washer or contact element 17 fixed with base 2 in any suitable way.
  • the spring engages a guide Washer 15 slidably fitting the counterbore and fixed with feeler 13.
  • Head 16 and washer 17 are of electrically conductive material and are normally in contact due to the action of the spring.
  • a bushing 17b of dielectric material insulates the stem of feeler 13 from washer 17.
  • Leads 16a and 17a extend from head 16 and washer 17, respectively, and are electrically connected when the head and washer are in contact as shown upon FIGURE 3. When feeler 13 is pressed upwardly however, against the urge of spring 14, connection between the leads is inter rupted.
  • a boot 18 of rubber or other flexible impervious material fits about the top of body 2 and about stem 3 to protect the feeler mechanisms and electrical contacts.
  • Stem 3 has a gage cap fixed thereto.
  • the cap has a cavity in its lower surface, shaped accurately complemental to the normal form of the upper end of the jars or containers to be tested.
  • the cavity is so shaped that if dimension A, FIGURE 1, of the jar is accurate, the outer circumferential skirt portion 12a of the cap will fit down smoothly over and about the upper body portion of the jar and thus determines that the diameter or geometrical outline or contour thereof is accurate.
  • the upper portion of the cavity has a reduced diameter indicated at 12b, closely equal to that of the outside diameter or contour of the top rim of the jar.
  • the cavity of cap 12 has a cylindrical or regularlyshaped geometrical protrusion 12c extending centrally downwardly and sized for an accurate gaging fit within the neck of the jar, so that it acts to gage dimension C, FIGURE 1.
  • the bottom surface of base 2 is, as shown, complemental to that of the upper or inner surface of the bottom of the jar. Consequently if dimension D, FIG- URE 1, is correct in a jar under test, the base will fit down accurately over and into surface contact with the bottom of the jar. But if there are one or more needles or other surface imperfections present, base 2 will be held thereby out of its normal lowermost position and feelers 13 will not be pressed upwardly but will remain in the position shown upon FIGURE 3.
  • cap 12 is so positioned on stem 3 with respect to base 2, that when the base fits down accurately into contact with the interior surface of the jars bottom, the cap also accurately fits down over and about the upper end thereof.
  • the feelers 13 are pressed upwardly so that head 16 of each is separated from its Washer 17.
  • base 2 may have three of these feeler assemblies spaced 120 equi angularly about the axis of stem 3.
  • the invention is not limited to any particular number of these feelers.
  • stem 3 is prevented from a full downward stroke, either by cap 12 or by base 2, or both. In such cases stem 3 will slide upwardly in and with respect to slide 4 as the latter descends to its lowermost position. It will be understood that the invention is not limited to use with cylindrical jars. It may, for example, have equal utility in the testing of jars which are generally square or of other shape in cross section.
  • base 2 and cap 12 are accurately shaped and colocated, and have the proper rotational position about the common axis of the slide, stem and base, so that the latter may freely enter a jar of acceptable form and dimensions, the invention is useful for containers of any regular geometrical form in horizontal section.
  • FIGURE 4 shows schematically a circuit diagram of the principal of operation of the tester. It has been previously stated that the instrument may include three feeler assemblies like the one shown upon FIGURE 3. The three are identified at 16, 17; 16', 17 and 16", 17". It will be noted that each of the c ntacts 17, 1'7 and 17 are connected with a common lead 18, in series with a resistance R. Each contact 16, 16', 16" is connected with a respective one of the leads 18, 18' and 18". By means not shown, these leads are connected simultaneously with the common lead through resistance R at the instant that slide 4- is in its lowermost position.
  • FIGURE 5 shows a circuit diagram for controlling and Operating the tester.
  • the diagram of FIG. 5 provides therefore means by which the testing circuits are controlled before each testing operation and an alarm signal actuated if the circuits are defective While all containers are eliminated as long as the apparatus has not been repaired.
  • transistor T is blocked. A positive electric impulse is then fed successively through leads 18', 18, 18". If contacts 17, 17', 17" are closed, transistor T cannot become conductive. If however one of leads 17, 17, 17" is open when the impulse is fed, which would mean that the tester is defective, transistor T will become conductive and the impulse will be transmitted by lead 19. This impulse is used to activate means (not shown) which will simultaneously give the alarm and reject all tested containers.
  • transistors T and T are saturated.
  • the controlling circuit is unoperative. An impulse is then fed simultaneously over all leads 18, 18', 13". If one or more of contacts 17, 17', 17" is not opened, which would mean that the container tested is defective, transistor T becomes conductive and an impulse will be transmitted through lead 20.
  • each container is accurately disposed in vertical alignment with and beneath base 2, it is gripped between a pair of movable arms or jaws one of which is identified at 11, FIGURE 2, and thereby raised slightly.
  • the container is thus momentarily fixed and immobilized. Practically instantaneously thereafter, a rotation is imparted to shaft 7a while the position of the feelers and the condition of the circuit is rapidly tested while base 2 moves downwardly to fit over the bottom of the container. If the tester is defective for some reason, the container is immediately discarded and the alarm is sounded. If however the tester is operative, and the container free of defects, base 2 fits down accurately over the bottom thereof and cap 12 fits down accurately over the mouth thereof. All three feelers such as 13, are raised and all contacts 16, 17; 16', 17 and 16", 17" are opened.
  • the impulse activates means (not shown) by which the container is ejected. If the container is free of defects the impulse is not transmitted through lead 20 and the ejecting means are not activated.
  • stem 3 and slide 4 with electrical contacts closed by and in response to upward movement of the stem in and relatively to the slide, the instrument may be useful for gaging the dimensions A, B and C, FIGURE 1.
  • Base 2 and the portion of stem 3 below the cap might then be omitted.
  • the aforesaid contact would be included in an external circuit including signal means, or means automatically expelling the defective container from the production line, in response to closure of the contacts.
  • Stern 3 and base 2 can be either rigidly connected one to another or base 2 can be allowed to freely take a vari able inclination in order to come into surface contact with an inclined bottom of a container.
  • the yielding connection between stem 3 and base 2 can be obtained by connecting them through a packing of some flexible material such as rubber (3a on FIGURE 3) or with a ball joint provided between stem 3 and base 2.
  • Containers having slightly inclined bottoms which are not dangerous and quite usable in most cases are not detected and rejected by this arrangement.
  • conductive means electrically conductive.
  • Terms such as vertical, downwardly, etc., as used in the claims are for convenience and clarity only and are not to be interpreted as limiting the invention to use in any particular angular position.
