13 Claims.
This invention relates to improvements in delivery and control mechanisms for printing or like machines and more particularly relates to a choke detecting device for use with delivery mechanisms whereby possibly damaging chokes will be detected and the machine promptly stopped, to avoid damage to the parts thereof.
In printing and like machines, chokes caused by products becoming collected and jammed between the various parts of the delivery mechanism frequently occur, causing broken machine parts, and considerable inconvenience and loss of time, due to stoppages, required to repair the parts and to release the choke. Chokes have been found to occur after the products have passed the folding rollers of a delivery mechanism and are disposed between the receiving fan and a product guide, while being carried from the rollers to a delivery belt or other conveyor.
One of the objects of this invention is to provide in association with a delivery mechanism, means to detect the presence of a choke and to cause the immediate stoppage of the machine when the choke assumes proportions approaching a predetermined damaging degree.
Another object is to provide in a delivery mechanism, a product guiding member which, upon being moved by a collection of products pressing thereagainst during the formation of a choke, will be caused to detect a damaging proportion thereof and to operate a control to prevent further operation of the machine.
A further object is to provide in a delivery mechanism, a product guiding member which is movable by an unwarranted collection of products between it and a part of said delivery mechanism, and is adjustable to predeterminably limit the degree of such collection of products before such movement occurs, and is adapted when so moved to operate a machine control, which is adjustable for actuation thereby, after a predetermined degree of such movement has taken place.
It is also an object of this invention to provide a delivery and control mechanism for printing machines of generally improved construction, whereby the device will besimple, durable and. inexpensive in construction, as well as con vcnient, practical, serviceable and efficient in its use.
With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts, and in the details of construction hereinafter described and claimed.
The preferred embodiment of the invention is illustrated in the accompanying drawing wherein the features of the invention are somewhat diagrammatically shown, embodied in a delivery and folding mechanism of a printing machine for printing newspapers and like folded products; another position of some of the parts being shown in dotted lines.
The printed web ll, leading from a printing or like machine, is shown running between a folding cylinder [2 and a cutting cylinder is from which it is fed between a pair of folding rollers l4 and 15, in the form of a folded sheet it, into pockets [1 of a rotatable fan or fly [8. From the fan I8 the folded sheets 16 are deposited on delivery belts l9.
During their passage from the rollers I4 and i5 to the fan IS the products It, in some instances, bunch up in the position indicated in dotted lines at 2|, causing a choke to be formed between the fan I8 and a product guide 22, usually provided at this point. The guide 22 is herein shown secured to a shaft 23 supported in an end of a supporting member 24, having an extended stem portion 25. The stem portion 25 is supported for sliding movement in a bracket 26 secured by screws 21, to a machine frame part 28. A spring 29, disposed between the bottom of a counterbore 3i formed in the bracket 26 and a shoulder 32 formed on the stem 25, tends to urge the guide 22 in a direction toward the product i to maintain the guide in its normal product engaging position, as shown in full lines in the drawing, but permits movement of the guide 22 in a direction away from the product, to the position shown in dotted lines. The guide 22 is freely rockable about the shaft 23 as a pivot, and is provided with a curved face disposed adjacent to and partially embracing the periphery of the fly or fan 18. The guide 22 cooperates with the pockets H to hold the products on the fly i8 while they are being carried thereby past the guide and, by cooperation with the periphery of the fly l8, confines the loose product ends extending from the pockets l1 substantially until the products are in position to be deposited upon the delivery belts l9.
Adjustment of the guide 22 to vary the normal product engaging position thereof, is made possible by the threaded engagement of a stop collar 33 with the threaded end 34 of the stem 25. The collar 33 may be secured in position on the stem 25 by means of a set screw 35. By cooperation with the end of the bracket 26 the collar 33 determines the normal position of the guide 22 in respect to the product It and the fan 98. Any thickness of products in excess of the determined allowable amount will move the guide 22 and its stem 25.
To immediately detect and obviate the formation of possibly damaging chokes, a control device, herein including an electrical switch 36, is provided. The switch 36 is connected by conductors 3'! and 38 to the motor controls of the printing machine (of which the cylinders l2 and l3 form a part), and is normally in closed circuit condition. Opening of the machine motor circuit by actuation of the switch 36 causes the immediate stoppage of the machine and the prevention of damage to the delivery mechanism.
Provision is herein made to actuate the switch 36 by movement of the guide 22 by an excess of collected products, through engagement of a collar 39, threadingly adjustable on the stem 25 and which is securable thereto in adjusted position thereon, by a set screw 4|. The collar 39 may be adjusted on the stem 25 to engage an operating member 42 of the switch 36, when moved with the stem 25 by the guide 22, to cause actuation of the switch 36 into open circuit condition, whereby the machine motor will stop, and thus cause stoppage of the feed of products to the delivery mechanism.
The switch 36 may be adjustably mounted upon a stationary part of the machine or, as shown, secured to the bracket 26 by a strap member 43 to dispose its operating member 42 into the path of movement of the collar 39. The collar 39, by being adjustable on the stem 25, permits adjustment of the device to permit a predetermined thickness of products to be collected and to pass the guide 22 without causing the switch 36 to be actuated to effect the operation of the machine motor.
The provision of the choke detecting and control device described above, and as illustrated in one form in the drawing, permits a predetermined thickness of products to be collected and passed to the conveyor I9 without the formation of damaging chokes, while preventing the collection of large excesses of products beyond the determined amount by detecting the same and stopping the machine with its associated delivery mechanism, beforedamage occurs. Due to the adjustable features above describe-d, a predetermined number of products may be collected and passed, and slight excesses therein permitted, before the switch 36 is actuated, making the device particularly useful under the varying conditions met with in printing newspapers and like products.
It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, and it is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, and it will be further understood that each and every novel feature and combination present in or possessed by the mechanism herein disclosed forms a part of the invention included in this application.
