Switzerland, assignors to J. Bobst and Son SA, Lausanne, Switzerland, a corporation of Switzerland Filed Feb. 19, 1963, Ser. No, 259,552 Claims priority, application Switzerland, Jan. 23, 1963, 821/63 Claims. (Cl. 93-36) The present invention relates to an element with picking spurs for the ejection of cut or punched waste in paper or cardboard sheets and to a member bearing that element.
There are various known methods for ejecting such waste, one of which consists of removing the waste by means of members pushing them out of the sheet plane, for instance with punches, which requires momentary immobilization of the sheet, while another method employs means permitting the ejection while the sheet is in motion, by the use of elements with picking spurs distributed on the periphery of; rotatory members which when passing the sheet embed themselves into the waste, pull them away and are subsequently stripped of the waste by scrapers.
It is evident that such elements with picking spurs are to be fitted on the rotatory members bearing them, so as to be embedded into the Waste, but not into the useful punched parts, what implies that their position should be adjustable within wide limits.
This condition has for instance already been fulfilled by elements with picking spurs which are screwed in the holes of a cylinder or in cases in which the adaptability is increased by insertion into circular grooves, wherein the spurs are locked by means of threaded members which require the use of a tool.
It has also been proposed to make such elements with picking spurs of metal sheet material bent appropriately and placed on projections of the periphery of a corresponding cylinder. Apart from the fact that the making of a cylinder, the whole surface of which is provided with projections is expensive, this arrangement has the disadvantage that the location of the element with picking spurs is fixedly determined by that of the projections.
The element with picking spurs according to the present invention is of the type made of a single metal sheet bent and shaped in the form of a U, with a fiat web and two lateral branches or shanks, one of which at least is terminated by at least one spur, one of its branches presenting at least a locking member protruding laterally outward in the direction of the said spur, the possible elastic deformation of the branches and the locking member allowing the introduction of the element with picking spurs into a groove of the element supporting the same, completed by a lateral groove in which the locking memher is notch-inserted so as to hold back the element with the picking spurs.
To fix the position of the element with the picking spurs, holes can be drilled in the bottom of the legs bounding the groove of the member accommodating the U shaped piece, said element having feet obtained by outward bending of cars or flaps which are part of the body of the element with the picking spurs, said feet penetrating into the holes.
The attached drawing shows three embodiments of the invention given by way of example, and wherein:
FIG. 1 is a view in perspective of the element with picking spurs according to a first embodiment of the invention.
FIGS. 2 and 3 are sections of the member of the ejection device, which support the said element with picking 3,215,349 Patented Nov. 2, 1965 spurs, FIG. 2 being taken along line II-II of FIG. 3, and FIG. 3 being taken along line III-III of FIG. 2, and
FIG. 4 is a section similar to that of FIG. 3, but showing a third embodiment.
The element with picking spurs of FIG. 2 is made of a single metal sheet shaped and bent in U shape, so as to form a narrow flat web 1 and two level parallel branches 2 and 3 perpendicular to the plane of the web.
Each of the free edges of the branches are terminated by three spurs 4, so that the element with picking spurs present in all six spurs, but there could be any number of spurs, generally less than six.
In the branch 3 are punched two locking members 5 and 6 protruding outward and in the direction of the spurs 4, but adapted to be brought back in the branch plane by elastic bending. Between these locking members the branch has a central hole 7.
Finally, at both ends of the web 1 are ears 8 and 9, bent downwardly so as to form feet.
The member of the ejecting device designed to accommodate the elements with the picking spurs will be a rotary member of disc or cylindrical form of which FIGS. 2 and 3 represent a portion 10, cooperating with the opposite rotary member or counter-part 11.
The rotary member 10 comprises circular grooves 12, only one of such grooves is absolutely necessary, of such width so as to make it possible to introduce therein, with friction, the elements with the picking spurs (see FIG. 3). The depth of the grooves is shallow so that the spurs 4 protrude from the groove. The spurs are designed to penetrate into the corresponding circular grooves 13 of the counterpart 11. This arrangement known in itself, allows, by causing the punched sheets to run between 10 and 11, for instance in the direction of the arrow 14, to cause the spurs of the elements with picking spurs to penetrate into the waste for the purpose of picking out the waste.
The elements with picking spurs are held in position by the tongues 5, 6 which are elastically engaged in the housing by being locked in a lateral circular groove 15 opening into each main groove 12. Thus, the element with picking spurs cannot be removed from rotary member 10, but can be shifted along the grooves.
The feet 8 and 9, however, can penetrate into the holes 16, which are drilled radially in the bottom of the main groove 12 to position the picking spur elements along the groove 12.
It is evident that these holes, like the projections which the present invention avoids, fix the picking spur elements in certain unchanging positions. But, whereas there is no possibility of displacing the projections or making new ones, it is easy to drill all the blind fixation holes 16 to provide for as many intermediate positions as desired.
To remove a picking spur element which is set in its groove, it is sufiicient to seize its spurs and urge the two branches elastically towards each other, until the locking members 5-6 are disengaged from the lateral groove 15, and can then draw the element outward, which can be facilitated by the insertion of a hook into the hole 7.
Thus, the installation and removal of the picking spur elements is exceedingly simple. Further, it is also very simple to modify at will their location on the periphery of the supporting element 10.
Finally, if it is desired to modify the clearance of the spurs by drawing them closer together or further apart than the width of the groove 12, the two embodiments shown in FIG. 4 may be utilized.
FIG. 4 shows a section identical with that of FIG. 3.
4 is a waste picking device such as that already described with normal spacing of the spurs, according to the first embodiment of the invention.
17 is a waste picking device according to a second embodiment, with closer spaced spurs.
This closer spacing is obtained by bending inward the branch 18 towards the branch carrying the locking members, so as to bring the spurs 19 towards the spur 17. This branch will, of course, be initially longer than the other, so that all the spurs will ultimately be at the same level.
The waste picking device 20, according to the third embodiment is, on the contrary, of the kind with spurs at increased spacing, which is obtained by an outward bending of its branch 21 to locate its spurs at 22. However, it will be preferable in this embodiment to bevel the groove of the rotary member 23, to accommodate the waste picking device in the manner illustrated at the groove at the farthest right in FIG. 4.
What we claim is:
1. In combination, a picking spur element adapted for picking waste from sheets, and a member supporting the spur element, said spur element being of U shape and including a Web and two upright flanges extending entirely lengthwise of the Web, at least one of said flanges having an upper end and including spurs at said upper end, said member which supports the spur element having a con tinuous groove in which the spur element is inserted with the flanges elastically engaged in the groove and the spurs extending beyond the groove, said web resting over its entire extent on the supporting member at the base of the groove, said spur element being movable longitudinally along said groove, said member further having a continuous lateral notch coextensive with and opening into the groove, said spur element including an integral locking member projecting outwardly from one of said flanges and elastically engaged in the said lateral notch in said member to thereby radially secure the spur element in the groove while permitting movement of the spur element longitudinally along the groove, and means on said spur element for engaging the member to secure the element in a particular longitudinal position along the groove.
2. The combination as claimed in claim 1, wherein said flange of the spur member in which the locking member is provided has an opening adjacent said locking member to facilitate removal of the spur member from the supporting member.
