Patented Nov. 9, 1948 LARD SPRAY CONTROLLING MEANS Ralph M. Mero, Chicago, Ill., assigner to Continental Can Company, Inc., New York, N. Y., a corporation of New York Application August 21, 1945, Serial No. 611,847
7 Claims.
The invention relates generally to spray controlling means and primarily seeks to provide novel means for controlling the spraying of lard, or the like, in to cans being fed in processional order to a filling station whereat meat or other products are to be lled thereinto.
When it is desired to lill meat into cans it is customary to spray lard into the cans prior to the illling thereof in order to prevent the meat from sticking to the cans when being removed by consumers. Spraying system-s automatically controlled so as to prevent operation of the spray head when no can is in position to be sprayed have 4been provided, but in such systems of which I am aware, no provision has been made to assure against continuous and obviously objectionable operation of the spraying head when conveying means on which the cans are carried is stopped with the control devices in condition for continuing the `spraying operation. Therefore, it is an object of the present invention to provide in combination with means for feeding cans in processional order and means for spraying lard or other fluid substances into such cans, novel means for controlling the spraying operation and `eilective to stop the spraying operation in the event that the feeding means stops with a can presented in position for receiving spray from the spray head.
In its more detailed nature the invention re` sides in providing in combination with can feeding and lard or other substance spraying means of the character stated, a solenoid valve for controlling the spraying means, a solenoid controlling circuit and a control switch connected in said circuit and disposed to be actuated by can contact for causing the valve to open while a can is passing the spraying means, and a timing relay unit connected in said circuit and normally operalble to maintain the valve open control condition, subject to said control switch, and operable in the event that the can feeding means stops with a can in contact with said control switch to break said circuit and prevent continuous spraying into the can stationary opposite said spraying means.
Another object of the invention is to `provide in control apparatus of the character stated a timing relay unit including a switch which is normally closed and connected in series with a coil of the solenoid valve and the normally open can contact closed switch, and means for causing the timing relay unit switch to open each time a normally recurring opening of the can contact closed switch is delayed a predetermined amount over and above the normal interval of spraying of an individual can.
With the above and other objects in view that will hereinafter appear, the nature of the invention will be more clearly understood by reference to the following detailed description, the appended claims, and the view illustrated in the aecompanying drawing.
In the drawing:
Figure 1 illustrates diagrammatically means for feeding cans in processional order, means for spraying a fluidl substance into the passing cans, and the novel control device comprising the invention. l
I1 l Figure 2 is an enlarged fragmentary view showing the can engaging element projected into the space provided fbetween rounded corners on two cans being fed -in end abutting relation.
Figure 3 is a fragmentary view illustrating the diaphragm attached 'block lowered to the position in which it causes the actuater to open the normally closed switch of the timing relay unit.
In the diagrammatic illustration herein. made of one example of emlbodiment of the invention, 5 designates a feedway over which cans 6 having rounded corners 'i are fed in processional order and at random spacing by any suitable conveying or feeding means such as the block chain 8. In such processional, random feeding some cans may abut and have only the spaces between them provided by the` adjacent rounded corners, as at 9, or they may have short or long spaces therebetween as indicated at l0 .in Figure 1.
While being fed along in the manner stated by the feeding means 8, the cans pass under a spray head Il and have fluid substance sprayed thereinto. While the invention is adapted for more general uses, it is particularly adaptable to use in controlling the spraying of lard into cans which are to be filled with meat. The feeding means referred to may form part of a filling machine, a feed line for feeding cans t-owarda filling mechanism, or toward a hand lling station, or the control devices may be combined with a feeding means for cans to Ibe sprayed for other reasons.
The spray head diagrammatically indicated at Il is fed through a duct I2 and controlled 'by a solenoid valve I3. The valve is automatically controlled t-o spray Vthe fluid substance when a can is passing therebeneath, and in the event that operation of the can feeding means 8 should be discontinued so as to bring a can to rest beneath the operating spray head, means is provided for automatically discontinuing the sprayl after a predetermined interval of time.
The novel control means comprises the solenoid valve I3, a normally open feather switch gener- 3 ally designated I4 and which is disposed in the manner illustrated in the drawing for being actuated by passing cans, and a timing relay unit generally designated I5.
The can actuated switch I4 includes an element I6 engageable by passing cans, and means I1 actuated by said element each time it is engaged by a passing can for placingl the contact' maker I8 across the switch contacts I9 and 2l).
The timing relay unit may be of any approved type and in the present disclosure includes a housing 2 I divided into an upper chamber l22 and a lower chamber 23 by a diaphragm 24'. The diaphragm is connected as at 25 to ablock 2 6 which" is constantly urged by a spring 21 in a direction" for lowering the diaphragm 24. The block is nor- It is to be understood that each time the can normally, elevated position, but by reason of the fact that the fluid in the top chamber 33 of the housing 2| must bleed into the upper chamber 22 1...past thepin 38, the downward movement of the mally held against said diaphragm lowering\- movement by a support member 28 which will rbe valve 36, and said wall lalso has a bypass 31 restricted by an adjustably mounted tapered pin 36.
The timing relay unit also includes a normally closed switch generally designated 39, the contacts of which are normally bridged by a contactor 40 having a projected displafcer button 4I which is engaged Iby a pivotally mounted actuator 42. The free end of the actuator 42 is disposed to lbe engageable by a depressor 43 carried by the block 26 so that whenever the block 26 is permitted to move the diaphragm 24 downwardly a predetermined distance, the actuator 42 will fbe depressed and the contactor 40 will be moved away from the contacts in the switch 39, as shown in Figure 3.
The coil 44 in the solenoid valve I 3 is connected with a current source line 4'5, and `also as at 46 with one contact of the timing relay unit switch 39. The other contact of said switch 39 is connected as at 41 with the contact 20 of the can actuated switch I4. The other contact I9 of said switch I4 is connected with the other current source line 48. It will also be observed that the coil 32 of the timing relay unit 3| is connected as at 49 with the current source line 45, and as at 50 with the line connecting the contact 20 of the can engaged switch with one contact of the timing relay switch 39.
It will ibe apparent that since the normally closed switch 39 of the timing relay unit, the coil 44 of the solenoid valve I 3 land the normally open can actuated switch I4 are connected in series with the - current supply lines 45 and 48, each time the element I6 of the switch I4 is displaced by 'a passing can it` will close the switch I4' and hold the same closed until the can passes out of contact with said element I 6. This will serve to energize the coil 44 of the solenoid valve I3 and the valve will be opened and the spray head I I caused to spray the uid substance into the passing can. As soon as the can being sprayed moves out of contact with the element I6, the spraying operation will -be discontinued. This functioning of the apparatus will continue so long as the cans continue to be fed along in processional order in the manner diagrammatically illustrated in the Figure 1 of the drawing.
.block and the diaphragm are retarded, and as vlong as the can's continue to be fed in immediate 15 or'clgse succession, the block 26 will never-'be permitted to'ino've down far enough to engage the actuator member 42 and eiTect an opening of the timing relay unit switch 39. Under normal operation, as the switch element I6 moves off the trailing end of a can to permit the switch I4 to open and discontinue a spraying operation and also de-energize the coil -32 of the timing relay unit solenoid 3|, the spring 29 will lift the support 28 and the block 26 and the connected diaphragm 24 and the fluid in the upper chamber 22 will be rapidly forced 4through the check valve 36 into the top chamber 33.
Should the feed stop so as to place a can beneath the spray head I I and in position for holding the switch I4 in the circuit closed position which will ordinarily cause an objectionable, coutinuous operation of the spray head, the control devices function to discontinue the spraying operation after a predetermined interval determined by the adjustment of the tapered pin 38. Y
In this emergency, the block 26,will be permitted to move downwardly a distance suihcient to contact the actuator 42 and displace the contactor 4I) of the time relay unit switch 39, thereby breaking the circuit through the coil 44 of the solenoid valve I3 and discontinuing the spraying operation. So long as the can actuated switch I4 rcmains in the closed position, the coil 32 of the timing relay unit 3| will remain energized and the switch 39 of said unit will not be restored to its normal closed position. As soon as the normal feeding of the cans is resumed, however, the switch I4 will be opened and the system will be restored to normal operation.
It will be apparent by reference to Figure 2 of the drawings how the element I6 will move into the space 9 between cans provided by the rounded corners 1 of cans even though they be fed along in end abutting relation. This permits the end I6 of the contact lever to swing outwardly and break the circuit across the contacts I9 and 20 for a short interval of time, thus restoring the timing relay I5 to its original position shown in Figure 1. Thus should some can groups be advanced in a solid stream, or in other words in end abutting relation, as shown in one portion of Figure 1, the element I6 would move into each space 9 and momentarily break the circuit across said contacts I9 and 20 and in consequence, the action of 'the block 26` of the timing relay would be of a pulsating nature, traveling slightly downward incidental to each engagement of the element I6 in a space 9 and then being pushed back up into its original position| by the spring 29 lifting the core 3U after the current has been broken in the solenoidcoil 32. On the other hand, should the cans pass along with greater spaces between the ends thereof, as shown at other portions of Figure 1, theelement I6 will completely come to rest in each space between two cas. Whenever ment I6 so as to complete and maintain the cirl cuit across the contacts I9 ani 20, the solenoid coil 32 will be maintained in energized condition and the block 26 will be permitted to move down far enough to depress the member 42 and break the circuit across the contactor 40, thereby deenergizing the solenoid coil 44 and discontinuing the spray in the manner previously described. See Figure 3.
While one form of the invention has been shown for purposes of illustration, it is to be clearly understood that various changes in the details of construction and arrangement of partsrmay be made without departing from the spirit and scope of the invention as defined in the appended claims.
