TUBE-VIINIDiNG MACHINE.
Application filed November 3, 1921.
In the industrial arts tubes formed from strips or ribbons of paper and analogous cheap and flexible material are meeting with a demand, particularly in the mining industry where explosive cartridges are required for loosening strata and removing obstructions.
The present invention provides a machine which takes flexible strip material, such as these blasting tubes, forms the tube or other material into a package of predetermined size, severs the tube and delivers it, all in one cycle of operation, the several steps being entirely automatic.
While the drawings illustrate a preferred embodiment of the invention, as particularly applied to the packaging of blasting tubes, it will be understood that the invention is not limited to the form shown but may be otherwise embodied or applied to the packaging of other material without departing from the nature of the invention.

Serial No. 512,488.
Qorrcsponding and like parts are referred to in the following description and desig nated in the several views of the drawings by like reference characters.
A plurality of pairs of compressing and feed rolls are mounted upon the table l and are designated by the letters A, B and C. respectively. These pairs of rolls are mounted alike, the rolls of each pair being relativelv adjustable. Each pair of rolls is mounted in standards 10, which are vertically slotted, as indicated at ll, to receive bearings 12 and 13, the bearing 1 being adjustable by means of a set screw l l, which is threaded into 'the upper end of the standard it). The rolls are preferably hollow and are mounted upon shafts 15 which project and are onnected at corresponding ends by means of spur gearing 16. A drive chain Til connects a sprocket 51 driven from the shaft 8 with the lower roll of the pair A, thus driving the feed rolls at suitable speed. A drive chain 17 connects corresponding rolls of the pairs A and B. A drive chain 18 connects corrcspr'niding rolls of the pairs l3 and G. A drive belt 19 connects one of the rolls of the pair C with the tube forming mechanism not shown) supplying the pack aging machine forming the present inven tion.
It should be stated that the machine may of any capacity with reference to the number of tubes package-d at the same time. The machine illustrated is adapted to package two tubes at a single operation, and one mechanism is a duplicate of the other, hence a detailed description of one will sutiice for a clear understanding of both, and the n umher of mechanisms iay vary according to the required output of the machine as a whole. or other material to be .e supplied from any desired wn). The machin is parrated for tie packaging of fiid at the right hand-side of I aiown a mechanism 20 receiving tubing El and a damp sealing strip 22, the mecl'ianism 20 being effective for pressing the scaling strip against the tubing to produce a s aled blasting tube 21. This tube is fed thr 1511 the rolls C, B and A, thus I compressing the tube, insuring the ienc-c oi the strio to the tube bed and finally supplying the tube to the ng mechanism which w-i'll now be de- Jed in detail.
Each crosshead 68 is provided with a projection dis-posed to cooperate with came 7 and 7 2 mounted on drum 70. select inward movement of the crossheads 68 to strip the package from the pins, and the corresponding cam 72 returns the cross head 68 to normal position after a packh-as' been discharged. Expansible helical springs 78 are mounted uponthe member and subserve the purpose of bumpers to suetain the impact of the inward movement of the crossheads-68- and to assist materially in the initial return of the crossheads to normal position. The cams for one stripper are placed ahead of the other pair. The corresponding return cams '72- similarly posed.
Consequently when the w" heads are stopped, a-package dischz from one head out of turn-with the other head. This successive discl clogging and simplifies matters for the op ator. A sprocket'T l is fast to an end portion of the shatt"7-5 upon which drums are mounted. A drive chain 76 connects the sprocket 74 witha sprocket 77 la. t to the shat-t8. In: this manner, the-package ejee ing mechanism derives motion from the shaft 8. A clutch member 78, mounted upon an end portion of the shaft 7-5 to rotate therewith, is normally urged into clutch engagement with the sprocket 7% by me? sot an ex pansible helical spring 79. A projection 80. on the clutch member 7 8, is normally engaged by the inclined or camend of alever 81, whereby=to held the shaft out of gear during the action of the package ejecting niechanisn'i. A pin 82, projecting laterally from the lowerend of the lever adapt ed to ride upon a cam 83 carried by the drum 52. When the pin 82 rides upon the cam 83, the upper end of the lever 81 ismoved to clear the projectionSO-and at this time. the spring 79 moves the member 7 8 into clutch engagement with the sprocket 7 4-, whereby the shaft 75 is rotated and the two cams7l, being one in advance of the other, more the cr heads 68 to successively ejectthe packages, the movement-being ol 'such duration as to ca'rrythecrossheads 68 inw d and then return them to normal position and at this instant the'pin'SQ, clears the cam 83, thereby permitting the'lever 81 to assume a normal position, whereby the projection 80 rides upon its cam endand disconnects the clutch member 78 fiOI-ll the sprocket 74: thereby throwing the ejecting or stripper mechanism out of action. An expansible helical spring 84 normally holds the lever 81 in predetermined position.
The cutting mechanism is disposed between the last set of compressing and teed rolls A and the oackage former, and comprises a fixed cutter 85 and movable cutters 86, the latter being preferably pivoted. A bracket 8?, secured to the table 4, supports the cutting mechanism. The cutters 86 operate between guides 88 and 89, the latter being disposed above the fixed cutter 85 and consisting of an L-bar, the horizontal wing of which is spaced from the cutter 85 to pro vide a passage for the tube. A plate 90, in line with the cutter 85, extends into the space formed between the rolls of the pair A and supports and gives proper direction to the tube on its way to the cutting mechanism. The cutter actuating mechanisms are duplicates 01 one another and a description of one will suflice as an explanation for both. A rod 91, connected with the outer end of the cutter 86, is pivoted at its lower end to an arm 92 which is fulcrumed at 93. A contractile helical spring 94 has connection at oneal extension 96 disposed to ride upon a cam 97 fast to the shaft 4?, whereby to hold the cutter 86 spaced from the cutter to admit of the passage of the tube between the cutters to the package forming mechanism. The cam 97 is formed with a notch 98 which is so disposed as to eFeot operation of the cutting mechanism to sever the tube when a package has been formed. lVhen the notch 98 registers with the lateral extension 96, the latter drops therein and admits or the cutter 86 operating by the action of the spring The action of the cutting mechanism is momentary, the cutter 8- moving across the path of the tube and severing the same and instantly returning to normal position by the lateral extension 96 riding out of the notch 98 and engaging the circular face of the cam 97.
Just prior to this cutting movement the cam 53 on the drum 53 actuates a lever 52-3 which lever controls a clutch through which the sprocket 51 is driven (see Figures i and 11). As above described, the sprocket 51 is connected by a drive chain 51 with the lower roll of the pair of feed rolls A so that the disengagement of the clutch 53 immediately stops the forward movement of the tubing, since the sprocket 51 is driven from the shaft 8 solely through this clutch mechanism. The forward movementof the tubing having now ceased, the winding heads no longer rotate, but the sprockets 57 slip on the sleeves 56. As soon as the severing or" the tubes is accomplished the heads again rotate to complete the winding of the severed tubes. The cams 52 and 5% then disengage the clutch members 59 to stop the winding heads and the packages are discharged successively from the heads by the action of the cams 71.
The disengagement oi the clutch members 59, of course, brings the winding heads to a stop and they remain stationary until the leading end of the tubing is supplied by the feed rolls. The clutch members 59 then again engaged and the winding continues until the clutch 56 is actuated as above described, at which time the winding stops and the sprockets 57 again slip on the sleeve 59 as above described. To prevent overthrow of the package former and insure the pins 62 occupying a relatively vertical position so l at the end of the tube may pass thercbetween preliminary to the next operation of the package forming mechanism, stop devices 99 and 100 are provided. The part 99 consists of a fixed rod attached to a convenient part of the machine, and the part 100 consists of a stop projecting outwardly from the clutch member 59. lVhen the clutch member 59 is moved outwardly said stop 100 extends across the path or the part 99, thereby bringing the shaft 56 to rest in a predetermined position, that is, with the pins 62 the one above the other in vertical position, as indicated most clearly in Figure 6.
After the upper strip 21 has been threaded through the tube forming apparatus, and with the adhesive strip 22 has been carried through the feed rolls A, B and C, the ma chine is ready to operate. It is started up just after having been turned beyond the point where the strippers 68 have been actuated, at which time the winding heads are stationary with the pins 62 in vertical relation. The timing of the cams is such that the feed rolls are put in motion before the winding heads, and a strip of tubing projected between the pins of each head from the feed rolls A before the heads commence to rotate. As they are rotated.v the pins of each head. wrap the projectin portion of the tube upon itself and commence to form a package of the form shown in my copeuding application Serial No. 535643, filed ruary l0,
The wrapping or" the tube continues for a period determined by the speed ratio of the winding shaft to the cam shaft, and it will be apparent that this speed ratio, together with the spacing of the pins 62, predetermines the size of the package which will be formed.
After a package has been formed, the winding head and the feed rolls sto as above set forth, while the movable knife 86 severs the tube. As soon as the tube is severed, the winding head again rotates to wind the severed end portion of the tube on to the package. The stopping of the head for out ting naturally follows from the stopping of the feed rolls, since the head is driven through a friction clutch, and as soonas the load is relieved by the severing of the tube, the head immediately rotates until the positive clutch has been thrown out of engagement prior to the stripping of the completed package "from the head.
It should be particularly noted that since the package is wound upon spaced apart members and takes a noncircular shape, the tubing, after it leaves the feed rolls A and before it reaches the package, is continuously oscillating. For this reason, the shearing" knife is placed in'in'iediately adjacent the teed rolls r to prevent interference.
