CONE-WINDING MANDREL.
Application filed February 3, 1925. Serial No. 6,638.
This invention relates to cone winding mandrels and more particularly to a means for gripping a blank and securing it to the mandrel, before and during the winding process, at a point outside of the lines of contact of the cutting knives in order that the waste ends of the cone may be completely severed from the useful center portion while the cone is still in position on the mandrel, and still allow the use of a feather edge on the inside of the cone.
In the accompanying drawing and following specification there is disclosed by way of example, only, a single illustrative embodiment of the present invention, but it is to be understood however that various changes can be made therein by those skilled in the art in the form, arrangement, proportions, size and material of the various partsshown without departing from the spirit ofthe invention or the scope of the appended claims.
In said drawing Fig. 1 is a side elevation of a cone winding mandrel constructed according to the.
present invention and showing the associated parts; r I
Fig. 2 is an end elevation looking from the right to Figure 1, the shafts being shown in section;
Fig. 3 is a partial side elevation of the mandrel on a larger scale showing the blank clamping mechanism, certain parts being broken away; and
Fig. 4 is a transverse section on line4-4 of Figure 3.
Fig. 5 is an end elevation showing only the driving means for the various shafts.
In winding cones and more particularly paper cones for use in the textile industries, it is important that thesize and shape of the cones be quite exact and it is highly desirable that both the inner and outer ends of the blank shall have a feather edge so that the finished cone may fit more securely upon the spindle and have a smooth outer surface for winding' Heretofore numerous methods have been suggested for securing the inner end of the blank to the cone winding mandrel to hold it during winding, but in most cases it has then been impossible to completely sever the waste ends from the cone while it is still on the mandrel owing to the fact that the gripped portion is held below the surface of the mandrel and thus out of the path of the trimming knives.
PATENT OFFICE.
These proposed forms of blank securing means do not allow the satisfactory use of a feather edge blank for the inner lap of the cone, nor do they allow the inner end to be gummed to the cone. The; present invention proposes to overcome the above difficulties by providing clamping means to secure the blankat a point without the useful portion thereof in order that a feather edge'blank may be used and completely trimmed on the mandrel.
Referring to the drawings, there is dis closed at 10 a conical mandrel which may be formed solid or hollow as desired and of,
-- of circular knives which are pressed against 1t at the completion of its winding, the surface of the mandrel is a true cone. It may extend some distance beyond the line 13 and does extend a distance beyond the line 12. Preferably it iscylindrical as at 14. This cylindrical portion and a part of the conical portion without the line 12, is provided with a loi'igitudinal groove or channel lo of any desired cross section adapted to receive therein'a clamping finger 16;which is flush with or below the surface of the man drel whenpressed into the groove as later described.
' This "clamping finger 16 comprises a strip of -metal shaped in crosssection to fit the groove and having a width but slightly less than the widthof channel 15 and of sufiicient thickness to give it considerable strength. It is pivoted intermediate its ends to the bracket 17 secured rigidly to the shaft 11 and extending radially therefrom. This bracket 17 is longitudinally slotted to receive between; its furcations the downward projecting'boss 18 on the finger 16, a pivot pin 19 being passed throughthese 'furcations and the boss to secure the finger 16 for rotation into and out of the channel 15. The finger 16 is normally retained in 'a position out 'of the channel 15 by means of the coilspring 20 interposed between the shaft 11 and the under side of the finger between the bracket '17 and the end of the mandrel. Suitable studs may be provided on the shaft and the under surface of the finger over which the coil spring slips to retain it in position. The right hand end of the finger 16 is downwardly curved as shown at 21, so that its end 22 may ride upon the conical end of the fingeractuating collar 23 which is slidably and rotatably mounted on the shaft 11.
The finger-actuating collar 23 is adapted to be moved longitudinally throughout a limited distance along the shaft 11 by suit able mechanism so that when moved to its extreme left hand position it forces the left hand end of the finger 16 tightly into the channel 15 but when moved to its right hand position allows the finger 16 to be raised out of the channel under the action of the spring 20.
The finger-actuating collar is controlled in its movement by the arm 24 pivoted at 25 to any suitable portion of the frame of the winding machine and having the stud 26 which if desired may carry a roller so positioned as to fit within and engage the side walls of the channel 27 in the cylindrical end of the finger-actuating collar so that movement of the arm 24 will be transmitted to and move the collar in a corresponding direction. The movements of the arm 24 are controlled by a face cam 28 mounted upon the shaft 29 and driven by any suitable connection, from the shaft 11. The cam 28 bears upon a cam follower 30 which may be a roller mounted upon a stud 31 projecting from the arm 24 so that when the high surface on the face of the cam engages this follower, the finger-actuating collar will be withdrawn from beneath the end 22 of the finger and allow it to be lifted out of the channel by the spring 20. A coil spring 32 serves to draw the arm 24 toward the left and thus press the finger 10 tightly into the channel 15 at such times as the cam follower does not contact with the elevated portion of the cam 28.
When the-device is being operated, a suit able blank of paper coated with the usual adhesive is brought either by hand or by a carriage as is well known in the art, to the surface of the mandrel while stationary and the cam 28 is in such a position as to allow the finger 16 to be lifted out of its channel. The end of the blank is then pushed beneath the finger and before rotation of the shaft 11 commences, the cam follower 30 is released by the elevated portion of the cam 28 and the spring 32 draws the arm 24 and with it the collar 23 to the left, thus pressing the finger 16 down into the channel and securely clamping the blank to the mandrel so that it cannot move either longitudinally or cir-- cumferentially of the mandrel, or be twisted in respect thereto.
It is necessary that the inner edge of the blank which is preferably feathered be securely pressed down and held against the surface of the mandrel before winding commences, so that the second layer of the blank will fit tightly against the first layer and the first layer will be securely pressed against the mandrel, to form a cone in which the various layers adhere to each other throughout their total area. As previously mentioned, the blank is covered with adhesive material and in order that its inner edge may be pressed down so that the adhesive will hold it against the blank, there is provided the wiper 33 formed of any suitable flexible material such as rubber, leather or cloth having a reinforcing metal backing 34. This wiper is passed downward against the feather edge and presses it into engagement with the mandrel to which it sticks. The wiper passes on by the mandrel to a position beneath it, at which time rotation of the mandrel commences. The slicker is then brought into engagement with the surface of the blank to securely press it against the mandrel to cause it to be tightly wrappedf The slicker remains in contact with the blank until the completion of the wrapping and causes the outside feather edge to adhere to the previous layer. This slicker comprises a bar or rod formed of any suitable material such as metal and of any desired cross section.
Both the wiper 33 and the slicker 35 are of sufficient length and so positioned as to contact throughout its full length with the blank when it is in position on the mandrel. They are mounted respectively on a pair of arms 36 and 37 radiating from the hub 38 which is rotatably mounted upon the shaft 39 securely fixed to the frame of the machine. The hub 38 and the arms carried thereby, are retained in a retracted posit-ion, such as shown in Figure 2, by means of the coil spring 40.
Movement of the hub 38 to first cause the wiper to pass over the surface of the mandrel and the slicker to then engage the surface of the blank, is caused by the cam 41 mounted upon the shaft 42 which may be driven by suitable mechanism so as to be properly timed in respect to shaft 11. A cam follower 43 is mounted upon the lower end of a curved actuating arm 44 which is pivoted at 45 to av projection 46 on the hub 38. A link 47 is pivoted to the actuating arm 44 at 48 and to the frame of the machine at 49 to restrain the lower end of the actuating arm 44 for movement in an are about the pivot 49 so that the follower 43 will always remain in engagement with the cam 41. Since in its position of rest the arm 46 is to the left of the center of the shaft 39, it will be seen that when the follower 43 rides upon the elevated portion of the cam 41 that upward movement of the actuating arm 44 will produce clockwise rotation lGO Ill)
the useful center portion.
of the wiper and slicker, as viewed in Figure 2.
Reviewing, the the operation of the device, it will. be understood that with the shaft and mandrel 11 stationary, the iingen actuating collar 23 will be moved to the o2;- treme right by the position of the cam 28. A blank of suitable paper, covered with ad hesive, will then be brought to the surface of the mandrel with its. end projecting beneath the finger 1G and its feather edge substantially. parallel to the element of the coneshaped mandrel with which it contacts. At this time the cam follower i3 begins to ride up on the cam -11 so that the slicker, which faces in the same direction as the main portion of the blank, is brought down into engagement with the blank near its edge and by its continued movement wipes over the edge toward the feathered portion, wiping it down so that the adhesive thereon causes it to stick to thesurface of the mandrel. The wiper then pass on to a position below the mandrel; rotation commences and the slicker comes into engagement with the surface of the blank under the action of the cam 41, remainingin engagement until the blank is completely wound upon the mandrel and serves to hold it tightly in contact therewith and secure the outer feather edge down to the last turn. With the slicker still in engagement with the cone, the diskshaped cutting knives, not shown,
are moved into engagement with the cone on the lines 12 and 13 severing the ends from The slicker and wiper are then returned under the action of the spring l0 to the position shown in Figure 2 and the cone stripped from the mandrel by any suitable well known mechanism, such as a. stripper mounted on the carriage which brings up the next blank for winding.
As an example of one method of driving the various shafts, reference should be had to Fig. 5 wherein are shown the shafts in end elevation. An electric motor is provided with an interrupted gear 51 adapted to drive the shaft 11 intermittently by means of its gear 52. The shaft 29 is pro vided with a sprocket 5?) which may be driven by a chain 5% from the sprocket 55 on the shaft 11. The shaft 42 is driven from the motor 50 by means of the chain 56 passing over the sprockets 5? and 58 on the motor shaft and the shaft 42 respectively. The above arrangement is only e7;- emplary and is not to be considered limitmg 111 any sense.
An important feature of this invention consists in the provision of means for securely clamping the blank to the mandrel at a point outside of the useful portion of the blank so that the complete trimming rtiy be done while the cone is still in engagement with the mandrel, thus giving the knives a surface to work against and eliminating any additional operations of trimming after the cone is removed from the mandrel. juuct to this method of gripping the blank :to the mandrel since it presses the feather edge into engagement with the mandrel and causes it to stick thereto during the of the nindlng. lVith this form of mechanism described, an extremely satisfactory o1 eration is obtained and per feet cones are made with a minimum number of rejects. The operation is simplified and cheapened. l'retter cones are produced and a feather edge can be used both inside and outside. thus infoducing the best possible known form of cone.
It is obvious that the gripping finger can be arranged at either end of the cone,
or if desired there may be one at each end, the method of operation of the finger being the ear that disclosed, or any other means may be used'such as a concentric rod and having a projecting stud with an inclined face to act on the end 22 of the finger. This rod may be pressed in and out by a lever at the end of shaft 11 acting against a spring.
