A jig which comprises a substantially planar base (8) and at least one of the locating pins is used to hold a plastics material during cutting and heat sealing of the material to form a blister or bubble package. <IMAGE>
Description
SPECIFICATION
Locating pin for a jig
The present invention relates to locating pins for jigs, to a jig incorporating locating pins and to a method of forming such a jig.
When packaging goods in so-called blister or bubble packs comprising a sheet of transparent plastics material having a depression therein for receiving the goods and heat sealed to a cardboard backing which closes said depression, it is usual to use jigs for locating the materials from which the component parts of the pack are cut out and to locate the component parts of the pack whilst these are heat sealed together. Such jigs generally comprise a substantially planar base, which is usually of plywood, and a series of spring-loaded locating pins which are movable against their spring bias when contacted by heating or cutting means moved towards the base to heat seal or cut the components of the pack.Hitherto the mounting of the locating pins in the base of the jig has been a costly and time-consuming operation because it has involved drilling apertures through the base of a size to receive the locating pins, counterboring the base from a reverse side thereof to receive an enlarged head of each locating pin, inserting each locating pin into a said counterbore head end last so that the opposite end thereof extends through the aperture associated with the counterbore, inserting a compression spring into each counterbore, and closing the counterbores by securing a plate or plates thereover.
The present invention has as its object to provide a locating pin for such jigs which will facilitate the manufacture of the jigs. The invention also has as its object to provide a jig, and a method of forming same, utilising the locating pins of the present invention.
The present invention provides a locating pin for a jig, the locating pin comprising a hollow body portion, a pin member having an enlarged head contained within the body portion and a stem portion extending through an aperture in the body portion, and spring means within the body portion resiliently urging the pin member towards an extended position in which the free end of the stem portion extends outwardly of the body portion.
The invention also provides a method of forming a jig of the kind comprising a substantially planar base and at least one locating pin mounted in the base, the method comprising obtaining at least one locating pin according to the present invention, forming an aperture in the base portion at the required
location of the at least one locating pin, said aperture
being such as to tightly receive the body portion of the locating pin, and mounting the locating pin in said aperture.
The invention further provides a jig comprising a substantially planar base and at least one locating
pin according to the invention mounted in an aperture in the base.
Preferably the body portion of the locating pin is of
hollow cylindrical form having an apertured wall at one end thereof through which the pin member extends and a wall which closes the other end thereof and acts as an abutment for said spring means. The cylindrical body portion may be of a predetermined outside diameter, e.g., may have an outside diameter of 12.7mm (1/2 inch) so that all that is necessary is to drill a hole of the appropriate diameter right through the base and then insert the locating pin in said hole. Likewise the cylindrical body portion may have a length which substantially accords with the thickness of the planar base of the jig, e.g., a length of about 27mm (one and one sixteenth inch).Preferably the pin member is of a length such that it can be moved against the bias of the spring means to a retracted position in which it is fully contained within the confines of the outer peripheral surface of the body portion.
Said spring means is preferably a helical compression spring, although any other suitable spring or resilient means may be used if desired.
For ease of manufacture and for cheapness both the body portion and the pin member are preferably formed from a suitable synthetic plastics material which is capable of withstanding the temperatures of heat sealing and which preferably also has self lubricating properties. A particularly suitable synthetic plastics material for the body portion and the pin member is nylon 6.6. The body portion and/or said pin member may also be formed from other suitable materials, e.g., a suitable metal or metal alloy.
The invention will be more particularly understood with reference to the accompanying drawings in which Figure 1 is a perspective view of a locating pin according to the present invention, and
Figure 2 is a diagrammatic sectional elevation of a jig incorporating such locating pins.
Referring to Figure lit will be seen that the locating pin illustrated therein comprises a hollow cylindrical body portion 1 in which is retractably mounted a pin member 2 which extends through an aperture 3 in an end wall 4 of the body portion 1.
Referring now also to Figure 2 it will be seen that the pin member 2 has an enlarged head 5 contained within the cylindrical body portion 1 and is urged towards its extended position shown by a helical compression spring 6 which abuts at one end against the head 5 and at the other end against an end wall 7 of the body portion 1.
The jig shown in Figure 2 comprises a substantially planar base 8, e.g., of plywood, having a recess 9 therein for the reception of the recessed portion of the transparent plastics sheet of a blister or bubble pack and a series of locating pins according to the
present invention the body portions 1 of which are a tight fit in bores 10 of suitable size in the base 8 and the pin members 2 of which project upwardly above the upper surface of the base 8 to locate either the components of a blister or bubble pack during heat sealing thereof orthe material from which the components of such a pack are cut during the cutting thereof. The pin members 2 are movable against the
bias of their springs 6 so that they will retract when contacted by a heat sealing or cutting tool 11 when this is moved towards the base 8.
It will readily be understood that all that is required to mount the locating pins in the base 8 is to drill holes of suitable diameter completely through the thickness of the base 8 and then to press the body portions 1 of the locating pins into said holes. This greatly simplifies the manufacture of such jigs and results in a considerable cost saving.
