The injection needle is made as support of the piston of the cylinder piston assembly and projects with its injection end out of the bottom of the cylinder housing of the cylinder piston assembly, wherein the injection needle is provided with a gas inlet opening (13) lying within the cylinder housing at the pressure side of the piston when the injection needle is in the working position.

Description

Apparatus for injecting gas, for example air, into a packaging tube or the like
The invention relates to an apparatus for injecting gas, for example air, into a packaging tube or the like, comprising an injection needle and a pneumatic cylinder piston assembly for moving the injection needle between a rest position in which the injection needle is spaced from the packaging tube, and a working position in which the injection needle projects into the packaging tube.
Such an apparatus is used in an apparatus for manufacturing packaging material for packaging vulnerable equipment and the like. To this end air is each time injected into a part of the packaging tube by the apparatus of the above-mentioned type, whereafter a seal is provided in transverse direction, so that successive air chambers are formed. The invention aims to provide a simplified apparatus of the above-mentioned type.
To this end the apparatus of the invention is characterized in that the injection needle is made as support of the piston of the cylinder piston assembly and projects with its injection end out of the bottom of the cylinder housing of the cylinder piston assmbly, wherein the injection needle is provided with a gas inlet opening lying within the cylinder housing at the pressure side of the piston when the injection needle is in the working position. In this manner an apparatus is obtained which is made very simple and can be manufactured at low cost. Moreover the apparatus is robust and has a long operational life. Further the apparatus according to the invention shows the important advantage that no separate provisions are required for providing the air supply to the injection needle, because the air supply is automatically enabled as soon as the injection needle reaches the working position.
Preferably, the injection needle passes sealingly through the end wall of the cylinder housing opposite of the bottom, wherein said gas inlet opening is provided in the circumferential wall of the injection needle in a part protruding out of the cylinder housing and being located within the housing in the working position of the injection needle only.
In the above-described apparatus for manufacturing packaging material the problem occurs that the packaging tube produced with successive, mutually separated air chambers can quickly accumulate near the apparatus. The invention aims to provide a solution for this problem and suggests an apparatus for transporting a packaging tube with successive, mutually separated air chambers, characterized by an arcuate transport path for guiding the packaging tube, a transporting means being movable back and forth along the transport path and a blocking means allowing the packaging tube to pass in transport direction and blocking the packaging tube in opposite direction.
The invention will be further explained hereinafter by reference to the drawings, in which an embodiment is shown. Fig. 1 shows very schematically an embodiment of the apparatus of the invention, wherein the injection needle is in the rest position.
Fig. 2 is a cross-section corresponding with fig. 1, wherein the injection needle is in an intermediate position.
Fig. 3 is a cross-section corresponding with fig. 1, wherein the injection needle is in the working position. Fig. 4 shows schematically a side view of an embodiment of the apparatus for transporting the packaging tube.
Fig. 5 schematically shows a side view of the apparatus of fig. 4 at a larger scale, wherein the transporting means and the blocking means are in a different position.
Fig. 6 shows a side view of the apparatus of fig. 4, corresponding with fig. 5, wherein the transporting means and the blocking means are in an end position. Fig. 1 shows very schematically an embodiment of an apparatus for injecting gas, for example air, into a packaging tube 1 indicated by a dashed line, said packaging tube 1 having an upper layer 2 and a lower layer 3. The apparatus shown is part of an apparatus for manufacturing packaging material not further shown and known per se, only a support shaft 4 being shown in the drawings. This apparatus can be provided with a plurality of injecting apparatus one next to the other for simultaneously manufacturing a corresponding plurality of packaging tubes. The apparatus is provided with a pneumatic cylinder piston assembly 5 with a cylinder housing 6 and a piston 7. The piston 7 is mounted on an injection needle 8 projecting with its injection end 9 out of the bottom 10 of the cylinder housing 6. At the opposite side the injection needle 8 sealingly passes through an end wall 11 of the cylinder housing 6.
As indicated in fig. 1 by an arrow, the cylinder housing 6 near its end wall 11 has an inlet 12 for compressed air for moving the piston 7 with the injection needle 8 from the rest position shown in fig. 1, in which the injection needle lies at a distance from the packaging tube 1 , into a working position shown in fig. 3, in which the injection needle 8 has pierced the upper layer 2 and projects into the packaging tube 1. In fig. 2 the apparatus is shown in an intermediate position, in which the injection end 9 touches exactly the upper layer 2 of the packaging tube 1.
In the part of the injection needle 8, which normally projects out of the cylinder housing 6, the circumferential wall of the injection needle 8 is provided with an inlet opening 13 which is located within the cylinder housing 6 at the pressure side of the piston 7 only in the working position of fig. 3. Thereby the air supply to the injection needle 8 is automatically enabled only when the injection needle projects into the packaging tube. As soon as sufficient air has been blown into the packaging tube 1, the air supply to the cylinder housing 6 is interrupted, whereby a spring 14 mounted between the piston 7 and the bottom 10, can move the piston 7 with the injection needle 8 into the rest position of fig. 1. A recess 15 is provided in the bottom 10 for receiving the spring 14. A bore 16 is connected with this recess, through which bore the air below the piston 7 may escape and can be supplied.
From the foregoing it will be clear that the invention provides a very simple apparatus for injecting gas into a packaging tube, which apparatus can be manufactured at low cost. Moreover manufacturing of the packaging apparatus, of which the described apparatus is a part, is simplified as no separate valves are required anymore for controlling the air supply to the injection needle. Fig. 4 shows a part of the packaging tube 1 with successive, mutually separated air chambers 21, which packaging tube is transported by a transporting apparatus 22. Thereby accumulation of the manufactured packaging tube underneath the injection apparatus cannot occur. The transporting apparatus 22 comprises an arcuate transport path 23 for guiding the packaging tube 1. Further the apparatus comprises a transporting means 24 which in the described embodiment is made with at least one transporting finger 25 rotatably supported by an arm 26 which is rotatably mounted in the centre of the arcuate transport path 23. The arm 26 is rotatable by means of a double acting cylinder piston assembly 27, the piston rod 28 of which is connected to the arm 26. The cylinder piston assembly 27 is rotatably supported at 29.
The transporting apparatus 22 comprises a blocking means 30 which in this case consists of a blocking finger rotatable around an axis 31. The radial distance between the axis 31 and the transport path 23 is smaller than the length of the blocking finger 30.
The transport path 23 is covered with Teflon for example, in order to obtain a low friction between the packaging tube 1 and the transport path 23. The end of the transporting finger 25 and the end of the blocking finger 30 are preferably provided with rubber so that a high friction is obtained between the packaging tube 1 and these ends. During operation the cylinder piston assembly 27 is operated in such a manner that each time the arm 26 is moved from the position of fig. 4 through the position of fig. 5 into the position of fig. 6 and back again into the position of fig. 4. During the forward movement the transporting finger 25 pushes the packaging tube 1 along the transport path 23, wherein the packaging tube can pass the blocking finger 30 without hindrance. During the backward movement the blocking finger 30 holds the packaging tube 1 and the transporting finger 25 can return into the position of fig. 4 over the stationary packaging tube 1 without hindrance. In order to obtain a good engagement between the transporting finger 25 and the packaging tube 1, the transporting finger 25 is provided with an engaging face 32.
If the not-shown apparatus for manufacturing packaging material produces a plurality of packaging tubes simultaneously, a corresponding plurality of transport paths 23, transporting means 24 and blocking means 30 are provided, wherein the transporting means 24 are supported by a common arm 26 and are simultaneously moved back and forth by the cylinder piston assembly 27.
The invention is not restricted to the above described embodiment which can be varied in a number of ways within the scope of the claims.
