Definitions

  • the electrostatic charge of the label is destroyed prior to application to the peripheral surface, and the label is thereupon electrostatically charged by one or more metallic strips which are applied to the peripheral surface and are connected to a source of high-voltage electrical energy during application of the label to the peripheral surface of the transfer member.
  • the present invention relates to a method and apparatus for manipulating labels or like sheetlike bodies. More particularly, the invention relates to a method and apparatus which can be resorted to in the application of labels or like sheets which carry symbols representing advertising matter, scales, instructions, designs, trademarks, warnings and/or other information which can used to designate the nature, mode of using and/or other characters of preferably plastic articles to which the labels are secured, either permanently or temporarily.
  • the invention relates to a method of applying labels to the peripheral surface of a preferably cylindrical transfer member which can be employed to deliver labels or like sheetlike bodies into a mold prior to filling of the mold cavity with a charge of plasticized material which is to form a cup, a box, a bottle or another plastic article.
  • Another object of the invention is to provide an apparatus which can be utilized for the practice of the just outlined method and which is capable of applying to the transfer member labels of any desired size, shape and/or consistency.
  • a further object of the invention is to provide a fully automatic apparatus which can apply labels to convex cylindrical or otherwise configurated surfaces of transfer members and which can apply the labels gently, without smudging and preferably in such a way that each label surrounds at least the major part of a preferably cylindrical peripheral surface of the transfer member.
  • An additional object of the invention is to provide an apparatus which can manipulate labels consisting of highly flexible or relatively stiff metallic, plastic, paperlike or other material, or of a combination of such materials.
  • Still another object of the invention is to provide an apparatus which can apply blank (unprinted) labels or which can be used for application of labels provided with symbols representing trademarks, decorative designs, instructions and/or other indicia.
  • One feature of the invention resides in the provision of a method of manipulating bodies of flexible sheet material, particularly of inserting labels in to the female die of a molding machine for synthetic plastic material.
  • the method comprises the stops of placing an imprinted label or a like body of sheet material between a shape-retaining first surface (which preferably constitutes the peripheral surface of a hollow cylindrical transfer member having a configuration complementary to that of the female die) and a deformable second surface (preferably the upper surface of a flexible tape or presser element whose end portions are held by carriages which are preferably comprises the additional step of maintaining the' second surface in substantially undeformed condition prior to movement of the one surface (preferably the first surface) against the other (second) surface.
  • a shape-retaining first surface which preferably constitutes the peripheral surface of a hollow cylindrical transfer member having a configuration complementary to that of the female die
  • a deformable second surface preferably the upper surface of a flexible tape or presser element whose end portions are held by carriages which are preferably comprises the additional step of maintaining the' second surface in substantially
  • the body of sheet material is applied to the first surface, it is preferably held against such first surface by suction, at least until the transfer member enters the female die of the molding machine. Since the second surface is preferably subjected to elastic tensional stresses, this second surface conforms to the outline of the first surface in response to movement of the first surface against the second surface (and more particularly against the label which is placed between the two surfaces by a suitable label dispensing and feeding unit of any known design).
  • the marginal portions of the label can be folded against the first surface in response to movement of the one surface against the other surface so that the first mentioned or median portion of the label is applied to the first surface in response to deformation of the second surface and that the marginal portions of the label are simultaneously applied to the remainder of the first surface.
  • the electrostatic charge of the label can be destroyed prior to movement of the one surface against the other surface to prevent adherence of the label to the deformable second surface, and the label can be electrostatically charged to adhere to the first surface during application to such first surface.
  • FIG. 1 is a side elevational view of an apparatus which embodies the invention, a label being shown in a position ready for application to the peripheral surface of a cylindrical transfer member;
  • FIG. 2 illustrates the apparatus of FIG. 1 with the label in a first stage of application to the peripheral surface of the transfer member
  • FIG. 3 illustrates the apparatus of FIGS. 1 and 2 with the label in the final stage of application to the peripheral surface of the transfer member
  • FIG. 4 is a top plan view of the transfer member
  • FIG. 5 is a perspective view of a molded article with a label incorporated therein.
  • the apparatus of FIG. 1 comprises a stationary base or main support 3 for a pair of upright holders or carriages l, 2 which are reciprocable along ways provided on the base so that they can move toward and away from each other.
  • Helical springs 4, 5 or analogous biasing means are provided to urge the carriages l, 2 away from each other and to the outer end positions determined by the length of a flexible weblike or tapelike presser element 6 whose end portions are preferably adjustably and readily separably affixed to the carriages.
  • the presser element 6 (hereinafter called tape for short) extends at a level above and abuts against the rounded upper end portions of two upright deforming members 7, 8 which are fixedly mounted on the base 3 in the space between the carriages l and 2.
  • the distance between the deforming members 7, 8 is constant.
  • the distance between the member 7 and the carriage 1 is preferably the same as that between the carriage 2 and member 8.
  • the carriages l, 2 respectively support two pivotable leverlike deflectors or arms 9, which extend toward each other i.e., toward theadjoining deforming members 7, 8.
  • the arms 9, 10 serve to support marginal portions ofa label 1 1 when the carriages 1, 2 are free to assume their outer end positions shown in FIG. I.
  • the axes about which the arms 9, 10 can pivot are normal to the longitudinal direction of the tape 6.
  • the transfer member of the apparatus comprises a hollow cylinder or drum 12 which is mounted in the space between the deforming members 7, 8 and is movable up and down as indicated by the double-headed arrow 12a.
  • the drum I2 is maintained in a horizontal position and the means for moving it up anddown may include a mechanical, hydraulic, pneumatic or electrical drive.
  • the mantle or shell of the drum 12 is formed with annuli of ports 13 and its interior constitutes a chamber which can be connected with a suction fan 14a or the like by way of preferably flexible pipe 14 containing a suitable regulating valve 14b (see FIG. 4).
  • the valve 14b can connect the chamber of the drum 12 with a compressor 140 or another suitable source of compressed gas when the chamber is disconnected from the fan 14a, or vice versa.
  • the peripheral surface of the drum I2 is provided with metallic strips or rings which have radially outwardly extending metallic pins or analogous projections (not specifically shown) adapted to be connected with a source of high-voltage electrical energy by way ofconductors 16 (FIG. 4).
  • the round end portions of the deforming members 7, 8 engage ,the underside of the tape 6 and the length of each of these end portions at least equals the width of the tape.
  • the electrostatic charge of the label 11 Prior to being placed onto the arms 9, 10 in a manner as shown in FIG. 1, the electrostatic charge of the label 11 is destroyedby any suitable means, not shown.
  • the means for feeding the label 1 1 from a stack or dispenser onto the arms 9, is of conventional design and its construction forms no part ofthe present invention.
  • the drum 12 is maintained in raised position so that it does not interfere with the feeding of labels onto the arms 9, 10.
  • the drum 12 is caused to move downwardly toward or against the tape 6 and to'the position shown in FIG. 2 whereby the lower part of its rigid shape-retaining peripheral surface engages the median portion of the label 11 and moves such median portion into engagement with the median portion of the'upper surface of the tape 6 so that the latter is deformed by the members 7 and 8 and causes the label to be applied to the peripheral surface of the drum.
  • Such application of the label is assisted by suction which is effective through the ports 13,'i.e., the valve 14b is then moved to a position in which it connects the chamber of the drum 12 with the suction fan 140.
  • the carriages 1,2 move toward each other, i. e., toward the respective deforming members 7, 8 and cause thesprings 4, 5 to store energy.
  • the free ends of the arms 10 move toward each other in response to movement of the carriages l1, 2 toward the deforming members 7, 8 whereby such free ends pivot and deflect the marginal portions of the label Illupwardly so that a larger part of the label is caused to move into contact with the peripheral surface of the drum 12.
  • the drum 12 continues to move downwardly toward (and if necessary beyond) the position shown in FIG. 3 whereby the median portion of the tape 6 undergoes progressively increasing deformation and causes a progressively increasing part of the median portion of the label 11 to abut against the peripheral surface of the drum.
  • the free ends of the arms 9, 10 continue to pivot and to move toward each other to thus effect further flexing of the marginal portions of the label 11 toward and into contact with the peripheral surface of the drum.
  • the length of the label 11 can (but need not) be selected in such a way that the label ultimately surrounds the entire peripheral surface of the drum 12 or that one of the marginal portions even overlaps a part of the other marginal portion. Of course, themarginal portions of the fully applied label 11 can remain spaced, at least slightly, from each other.
  • the drum 12 is then ready to transfer the label 11 into the female die of a mold for plastic articles or the like.
  • the cavity of the female die is preferably surrounded by a surface which is complementary to the peripheral surface of the drum.
  • the valve 14b continues to connect the drum 12 with the fan during such transfer of the label 11 to make sure that the label retains its cylindrical shape, i.e., that it continues to adhere to the peripheral surface of the drum.
  • the valve 14b is adjusted so as to connect the chamber of the drum 12 with the compressor 14c wherebythe ports 13 discharge jets of compressed gas which cause the outer sideof the label 11 to abut against the internal surface of the female die.
  • the circuit of the pins on the rings 15 is thereupon completed so that the label 11 is electrostatically charged and is' thereby caused to adhere to the internal surface of the female die in an accurately determined position.
  • the drum l2. is thereupon withdrawn from the female die so that the latter can cooperate with a male die to form therewith a mold cavity which is filled with plasticized material,
  • the label 11 which can carry advertising matter, one or more graduated scales, designs representing trademarks or other indicia of the owner or manufacturer, lettering or instructions to use one otherwise manipulate the articles, and/or other symbols.
  • the symbols are applied to the outer side of the label 11, at least when the material of the label is neither transparent nor translucent.
  • the drum 12 is ready to accept a fresh label 11 as soon as it is withdrawn from the female die so that it can be wrapped into such fresh label during the formation of an article in the mold.
  • FIG. 5 shows as an example of a moulded article with a label 11 incorporated therein or bonded thereto a drinking cup 17 formed of plastic material by an injection moulding machine whereby the outer side of the label 11 forming the outer circumferential surface of the cup 17 has a design of triangular sections 18, 19 which are alternately colored black and white. This design is part of the outer side of the label 11 which forms a homogene unit with the injected plastic material.
