M. RAWE SECURING DEVICE FOR V E-BAGS IN VALVE-BAG MANUFACTURI MACHINES Filed Oct. 1. 1954 Patented Nov. ll, T958 SECURING DEVICE FOR VALVE-BAGS IN VALVE- The present invention relates to a device for securing the valve-inserts inserted into valve-bags in correct position during the closing of the bottoms of the bags in a valve-bag manufacturing machine.
In paper-bag manufacturing machines of this kind it frequently happens that the valve-insert moves out of its correct position during the closing of the bottom of the bag, in which case, when hose-shaped valve-inserts are employed, leakage occurs at or beside the valve opening, which may be the cause of considerable trouble when the valve-bags-are used.
The object of the invention is to overcome this deficiency in the manufacture of valve-bags through the provision of holding means for. the valve-insert during the closing of the bottom of the bags.
For this purpose the invention provides the valve-bag manufacturing machine with holding means adapted to seize the valve-insert. The holding means are moved at the same speed as the valve-bag and are mounted to meet.
the valve bag on the side of the machine confronting the bottom-closing-side of the latter. These holding means consist preferably of pins which pierce the bottom of the paper bag and the valve-insert and thereby secure the valve-insert in it correct position during the closing of the bottom. The pins are fastened to conveying means adapted to move parallel to the bottom of the valve-bag.
conveying means for the holding pins 10. The holding The invention proposes to use an endless chain as conveying means. To the links of the endless chain are exchangeably secured pin-holding-means in which the pins are rigidly fastened.
Additional features and advantages of the invention will be understood from a consideration of the following detailed description taken in connection with the accompanying drawings, forming a part of this specifica tion and in which an embodiment of the invention has been shown by way of example. However, the invention is not limited to the example shown in the drawings, but includes any changes or modifications which mark no material departure from the appended claims.
-In the drawings, in which like parts are referred to by the same reference numerals,
Fig. l is a side elevation of an embodiment of the holding means;
Fig. 2 is a vertical section on line IIII of Fig. 1.
Referring now to the drawings in detail, the reference numeral 1 designates the valve-positioning-roller which seats the preferably hose-shaped valve-inserts 2 in the bottom of the valve-bag 3a fed into the machine on platform 3b as indicated by the arrow 3. Arranged above the device for the closing of the valve-bag-bottoni around the valve-insert 2 through folding of the lateral flaps of the bottom of the bag in downward direction, is positioned the holding device for the'valve-insert during the closing of the bottom. The holding device of the invention comprises a supporting member 4 of angular shape provided with chain- wheels 5, 6 and 7 and with a guide-wheel 8 for an endless chain 9, serving as movable pins are fastened in holding members 11 exchangeably secured by means of screw-threads or the like to the chain-links of the endless chain 9. The angular supporting member 4 is pivotally mounted with a supporting arm 12 which is adjustably fastened and secured in its adjusted position by mean of clamping screws 14 to a stationary bolt of the machine frame or to a shaft 13. In addition to this, the angular supporting member 4 can be pivoted with the supporting arm 12 about the driving shaft 22 for the chain-wheel 6 in upward direction into the dot-and-dash-line position. The member 4 may be thereby put out of action when disturbances occur and are to be removed in the bottom-closing-device underneath it. Through rotation of the supporting arm 12 about the bolt 13, after loosening of the clamping screws 14, the height of the angular supporting member 4 and of the endless chain 9 as well as the piercing depth of the holding pins 10 can be adjusted, and secured in the adjusted position by retightening of the clamping screws 14. The angular supporting member 4 is provided at its free end with a handle 15 for moving it out of its operating position in an upward direction. For the support of the supporting member 4 in the lifted dot-and-dash-line position illustrated in Fig. 1 the machine frame is provided with a movable spring-loaded supporting arm 17 provided with stop 23, while the supporting member 4 is provided with a cooperating stop 18. For rotating the supporting member 4 back into working position, the movable supporting arm may be swung temporarily against the action of its spring out of reach of the stop 18.
The third chain-wheel 7 is mounted on axle 19 adjustably supported in an elongated hole or slot 20, for tensioning of the endless chain 9.
The holding members 11 of the pins 10 are screwed into laterally projecting portions 21 of the chain-links of the endless chain 9. The chain-Wheel 6 mounted on the shaft 22, is driven by means of gear wheels, driving chains, belts'or the like. There are preferably two holding pins 10 arranged in parallel to every chain-link. When the bag 3a and the preferably hose-shaped valve-insert 2 move simultaneously into the position shown in Fig. 2 above the valve-seating-roller 1, the holding pins pierce the valvebag-bottom and the valve-insert 2 and thereby secure them in correct position relative to each other during the closing of the bag-bottom. The holding pins with the bag bottom and the valve pinned together travel over platform 3b in the direction of arrow 3. Only when the endless chain 9 and the holding pins 10 fastened to it are passing the driving wheel 6, that is, after the valve bag-bottom has already been closed through downward folding of the lateral flaps of the bottom, the holding pins 10 are automatically withdrawn from the bottom of the valve-bag 3a and from the valve-insert 2. The actuation of the endless chain 9 is effected in synchronized cooperation with the actuation of the valve-bag machine or with the bottom-folding device always in such manner that, a valve-bag, a valve-insert and the pair of holding pins arrive simultaneously at the valve-seating-point. The pins 10 automatically then penetrate into the valve-bag bottom and into the valve-insert and secure both of them in correct position with respect to each other until the bottom of the bag has been closed.
What I claim as new and desire to secure by Letters Patent of the United States is:
