SHEET-FEEDING MECHANISM.
Original application tiled IApril 10, 1.925, Serial No. 22,139. Divided and this application filed .Tune 3,
i i v1926. Serial No. 113,546.
The present application is a division of my CO-Pending United, States ,application Serial N o. 22,139, filed April 10th, 1925, and the invention described herein pertains to a construction for feeding lining paper and label wrappings in an automatic machine for eoverlng sweetmeats, soap, etc. The machines used for this purpose up-to-date do the work unsatisfactorily as a result of being constructed for a definite size of the objects to be Wrapped. The machines constructed for manufacture of sweetmeats, do not, however, deliver the manufactured articles of an equal size, thus necessitating the wrapping of the same by hand. This obstacle is in part overcome by the present invention which provides for the feeding of the paper wrappers to a subsequent apparatus for performing the wrapping of the article.
The invention is fully disclosed in the following description and in the accompanyin drawings in which; l
igure 1 is a side elevation of the device;
Figure 2 is al section on the line 2-2 of Figure l; and
Figure 3 is an elevation on the periphery of the intermediate wheel.
Reference to these views will now be made by use of like characters which are employed to designate corresponding parts throughout.
The label papers lie in a bundle on a stand 43 and are supported by pins 44. The stand 43 moves back and forth on a guide 45 by means of a pull rod 50. The labels are taken out from the bundle by means of a transporting device 55, which works on the vacuum principle and is attached to a rotating shaft 54. The vacuum is conducted through a hole 56 in the shaft to a duct 57, from which it is conducted to the suckingholes 6() through valves 58, which are opened when they strike the tip 59 of a plate 59 attached to the frame 52. When the valve has passed the tip, the valve stem is released and the valve closed by means of a spring 61. The transportin device rotates in the direction indicated Ey arrow 63. At the moment when the transporting device grips a label from the stand 43, the device and the stand have a parallel direction of motion, but the velocity of the stand is greater. At the moment when the transporting device brings the label into position c, the lining paper is there already. Both papers will thus come onto the sweetmeat, and a gripper mounted on the intermediate wheel 9 presses one end of the of the wheel.
'The gripper consists of a roller 65, mounted on a shaft 64 upon the U-formed periphery of the intermediate wheel, the roll-er protruding from the slot in the periphery. The roller is furnished with claws 66. The shaft of the roller is furnished with an arm 67, one end of which is supplied with a gliding roller 68. A spring 69, one end of which is attached to the intermediate wheel, the other end being attached to an extension of the arm 67, has a tendency to turn the arm thus pressing the claws 66 against the periphery of the intermediate wheel.
To the frame 52 is attached a segment 70. lVhen the gripper passesl the segment, the gliding roller rolls upon the upper surface of the segment, the arm 67 turns the shaft G4 and the claws are lifted up from the periphery. This takes place just before the position c is reached. The lining and label papers are pushed under the claws 66 at c,
papers against the' periphery the gliding roller 68 leaves the segment, and
the spring turns the shaft 64 by means of the arm 67. The papers are thus clamped between the claws 66, and the peripheryof the intermediate wheel. The intermediate Wheel then continues to another position where the sweetmeat and papers are taken up by the wrapping machine.
While a specific embodiment of the invention has been illustrated and described, it is to be understood that various alterations in the details of construction may be made without departing from the spirit of the invention as indicated by the appended claims.
Having thus fully described the invention, what I claim as new and desire to protect by Letters Patent is:
1. A sheet feeding mechanism comprising a sheet holding device, a rotary intermediate wheel, and a continuously revolving transporting device disposed between the sheet holding mechanism and the intermediate wheel, adapted to suctionally engage the lower sheet in the holder and to feed said sheet to the intermediate wheel and simultaneously engage the next sheet from t-he sheet holding device.
2. A sheet feeding mechanism comprising llO rotatably supported adjacent the holder, and a transporting device provided with dialnetrically opposed suction openings and havingr a vacuum chamberrformed therein communieating with the suction openings by means of a transverse channel, a spring operated valve at the end of said channel and means for periodically opening and closing the said valves' for engagement of the sheets.
In witness whereof, I have hereunto set my hand.
