July 5, 1938. A. J. HORTON CONTROLLING DEVICE FOR PRINTING MACHINES Filed Aug. 10, 1935 Patented July 5, 1938 UNITED STATES CONTROLLING DEVICE- FOR. PRINTING MACHINES ration of New York Application August 10, 1935, Serial No. 35,592
24 Claims.
This invention relates to printing'machines and more particularly to a control device therefore, whereby the machine may be protected against possible damage and inconveniences due to folder or like chokes.
In printing machines and especially in those wherein the product requires folding, chokes occasionally occur at or adjacent to the folding means, which usually comprises a pair of cylinders having cooperating means thereon, thereby causing severe strains and possible damage to the adjacent machine parts, or at least considerable inconvenience, if not promptly attended to and which usually requires the stopping of the press before operations can be continued.
Before such chokes occur, or at least become sufliciently developed as to cause damage, several conditions become existant. For instance, if the ,.product is beginning to accumulate, it is readily noticed due to the lack of a product being delivered, or by the presence of-a product upon the folding cylinder at an improper time. Whenever products fail to appear, or do appear but at improper intervals, a choke may be in the process 25 of development and immediate action must be taken to interrupt the same. Due to the rapidity with which chokes develop and become troublesome, and to the complicated nature of such printing machines, it is generally impossible to promptly note the indications of a choke and to avoid subsequent damage, by preventing continuance of the fault in time.
- Automatically operable means, including both mechanically and electrically operated mechanism's, have been provided, most of which operate only after a choke has occurred, and by using the accumulated pgiducts' to operate an actuating member to stop the printing machine. These devices require the occurrence of a choke to operate 40 them, which in many instances is sufficient to impose severe strains upon the machine parts, or cause considerable inconvenience and loss of time while the choke is being cleared. a
One of the principal objects of this invention is to provide a control device which is automatiproducts are received one at a time by a fan wheel PATENT OFFICE Still another object is to provide a printing machine control mechanism which is automatically operable upon the absence or presence of a product in a position before the proper time therefore, to actuate suitable devices to stop 5 further operation of the printing machine and to interrupt the feeding of products therethrough.
A further object is to provide light responsive electrical devices arranged to detect the absence or presence of a product at an improper interval 10 in the operation of a printing machine and to actuate mechanism to stop the machine or interrupt the flow of products therethrough, or both.
It is also an object of the invention to provide a control device for printing machines, of gen- 16 erally improved construction, whereby the device will be simple, durable and inexpensive in construction, as well as convenient, practical, serviceable and efiicient in its use.
With the foregoing and other objects in view, 20 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, it being understood that various changes in the precise 5 embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.
The preferred embodiment of the invention is illustrated more or less diagrammatically in the 30 accompanying drawing, wherein is shown the folding and delivery mechanism of a printing machine having associated therewith an arrangement and combination of features and devices constituting the control mechanism embodying 35 the feature of this invention.
It will be understood that the invention relates especially to printing machines wherein the products thereof are fed to folding and delivery mechanisms. Herein is shown a continuous web H' 40 being fed between a pair of cylinders l2 and I3 having cooperating mechanism for severing the web H as indicated at M. The severed portion 15 is carried by the cylinder i2 into position to be acted upon by a folding blade i6 which directs it between a pair of folding rollers i1 and I8. After passing between the rollers i1 and I8, the folded i 9 and delivered therefrom onto a suitable recciv- 0 ing member (not shown). Suitable means, generally an electric motor, is provided to drive the operating parts of the printing machine and suitable interconnecting mechanism insures the proper timing of the various components of the u the products in proper timed relation? The particular point at which most chokes occur, in printing or similarly operating machines, is after severing the web, and as the severed product? is folded. The products at this position occasionally accumulate, choking the mechanisms, whereby considerable damage thereto may result. At suchtimes, the product may not becarrieti beyond the rollers l1 and I8, (as shown atv 2|; into proper position to be acted upon by the blade l6. The productj under the above conditions, therefore, will not pass between the rollers ll and l8. Such discrepancies or irregularities in operation, when they occur, are probable indication that 'a choke is being developed, and interruption of the machine operation as soon as possible, is desirable.
A mechanism for automatically detecting the above irregularities and to actuate devices to stop operation of the printing machine or portion thereof eflected, is herein iiiustrated and will be hereinafter described. This mechanism is operated by the absene of a product at the proper time below the rollers l1 and I8 or by its presence at an improper time upon the cylinder |2 at It, but it is to be understood that it may be adjdsted to operate, due to the presence of a product at the first position at an improper interval or the absence of a product at the second position at the proper interval of machine operation.
The mechanism contemplates, in one instance, the interruption of the operation of the printing machine, and, therefore, provision is made for interrupting an electric circuit 22 which may control the operation of the driving motor by opening the switch 23. It is also contemplated to interrupt the feeding of the web, and an electrically operated web severing means or "knife 24 is provided for this purpose. The electrically operated actuating means for the knife 24 is under con trol of a solenoid switch 25. A solenoid 26 is arranged to operateboth the switches 23 and 25 but it is obvious that one or the other may be omitted if it is not desired to both stop the machine and sever the web.
Energization of the solenoid 26 will operate the switch 23 to open the motor control circuit 22 whereby the printing machine will stop. Simultaneously, the switch 25 will close and. energize the circuit 28 influencing a knife operating device 29, whereby the knife 24 will be swung downward to sever the web II in advance of the cylinders l2 and I3, and direct the oncoming portion away from them. The solenoid 26 is energized to actuate the switches 23 and 25 whenever, as hereinshown, a product is absent, at the proper time for the same, below the rollers l1 and I8, and also when a product is disposed on cylinder 52, at 2%, at an improper interval of time, although as stated above, their operations may be accomplished when a product is present or absent respectively from these positions at other times.
The means for controlling the energization of the solenoid 26 herein comprises a pair of devices, each consisting ofa light responsive electrical device such as a photo electric cell 30, and
a source of light 3E, operatively disposed adjacent to the path of the product. The light responsive electrical devices 30, are each arranged to operate associated controlmeans 32 to energize the solenoid 26 through circuits 33 whenever a beam of light strikes the light sensitive element thereof in a well known manner. T
at a point 36, a light 7 provided beneath the rollers l1 and I8 to reflect source of light may be an electric light, the beam of which is focussed at a point to be reflected back to the light responsive device 30 whenever a light reflecting surface is presented at the proper position, so to do. The electric lights 3| are each arranged to be energized by being, in a circuit 34 which at timed intervals is opened and closed by a timing switch 35. The :timing switch 35, it is understood, is operated in any convenient manner in synchronism with the operation of the printing machine, and particularly with that of the folding mechanism, to which the control mechanism of this invention is applied.
The timing switches 35, in this instance, are shown arranged to energize the light sources 3| and thus throw a beam of light upon the points past which the web must pass. Should there be a product present at point2| at an improper time or absent from point 36 at the proper time the light from this beam is reflected upon the sensitive element of the photo-electric cell' 30 and the solenoid 26 is energized, whereby the printing machine will stop and if a severing knife 24 is provideda'the web II will be severed. In this case I absence of a product is to be detected reflecting surface inust be "where the the beam from the source of light 3| adjacent the same, which may be, for instance, a mirror disposed at 31. If desired, however, the source of light 3| may be disposed in place of mirror 3'! and its beam directed so as to shine directly across the path of the product and upon the sen= sitive eiement of the cell 30.
The timing switches 35 may be of the form illustrated, wherein a cam 38 rotates in synchronism with the operation. of the printing machine and acts through the cam surface 39 upon an arm 4| to open and close the circuit 34 by means of cooperatingcontacts 42 and 43. As illustrated one of the switches 35 has its cam 33 arranged to actuate the arm 4| to close the circuit 34 and thereby tend to cause a beam of light from the light source to illuminate the reflector or mirror 31 during the interval a product is passing the point 36 from the rollers I! and I8 to the fan wheel is. The other switch has its cam arranged to cause illumination of a product, when the same has reflecting properties, during the interval it is not supposed to be present at the point 2| on the cylinder I2. In cases where the product does not have reflecting properties, arrangements can be readily made to provide a reflecting surface upon the cy'inder at the proper position to cause reflection of the light beam at 2| whereby the presence of a product thereat, at an improper time, will interrupt the beam of light and cause the control 32 to be actuated to energize the solenoid 26. This arrangement will merely require the reversal of the arrangement of the cam 38 controlling the source of right 30 directed toward point 2| to illuminate the same reversely to the previous arrangement. A reversal of the action of the control 32 adjacent point 2| will also be'required, whereby it will act to close the circuits 33 and energize the solenoid 26 when the beam of light reflected back from the reflecting surface provided on the face of the cylinder is interrupted by the presence of a productat 2|= In respect to the ability to reverse the action of the controls 32, it will be understood that these may include a solenoid controlled switch which, as is well known, may be arranged to either open or close a circuit when the solenoid thereof is energized. In the arrangement first described, such a switch may be utilized, which is closed when the light responsive device 3! adjacent point 2| is actuated by a beam of light from the product, and in the arrangement wherein a reflecting surface is provided upon the cylinder, the switch is arranged to close when the respective light responsive device is not actuated, due to an interruption in the beam of light from the reflecting surface on the cylinder.
The mechanism, which is operable as described above in connection with the description of its features and parts, provides an efllcient and substantially instantaneously acting protective device for a printing machine, to prevent severe strains and possibly expensive damage; with their attendant inconvenience and delay, due to chokes wherever such are liable to occur. The mechanism is not necessarily limited for use in association with the folding devices of a printing machine, as it is obviously adaptable for use in connection with other parts or mechanisms thereof, or of like machines, to detect the presence or absence 'of a product at improper intervals, at
any position where chokes are liable to occur,
during machine operation.
It will be understood that the invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof, andit is therefore desired that the present embodiment be considered in all respects as illustrative and not restrictive, reference being had to the claims rather than to the foregoing description to indicate the scope of the invention.
