Sypzo Omori, Tokyo / Japan Device for producing packaging ..

The invention relates to an apparatus for producing Packaging made from unshaped raw material, whereby kneaded, powdery or granular materials, e.g. sausage fillings, packed in tubular containers, tied and sealed at both ends »

There are already devices for the production of such containers known, but difficulties have arisen in using the flat metal brackets that are used to tying off the ends of the tubular container by compressing and thereby weakening the container material, that it later tears or because the container material actually tears and the contents are spilled »

"The material to be packaged is pressed out intermittently from the front end of the injection cylinder 2 of unit A" Figures 3 and 4 show the unit by which the setting is prepared and by which the material is pushed away from the tied cross-section is o 8, 8 ^! and 9, 9 'are two sets of holding plates which are closely opposed to each other in front of and on both sides of the injection cylinder 2. The toothed racks 1t, 11 · and toothed racks (not shown) that are actuated by the same shaft 10 engage in these holding plates. When the Filmsohlauch is filled with the emerging from the front end of the injection cylinder and the filling material is interrupted, the shaft 10 rotates in the direction shown in Figure 3 _e position to the right. At the same time, the holding plates 8, 8 ¹ and 9, 9? to the front and eject the material to both sides the nooke is moved in such a way that it is led a little forward and stops. The material present in the film tube is therefore pushed forward and the empty tube overlaps in the vertical direction and is stretched. Seen from above, the holding plates 8, 8 and 9, 9 move in the direction of the arrow in FIG both extended ends tied in two places by means of a V-shaped metal and the hose

is cut in the middle, then one can be tied off Packaging to be produced «

The one in the Pig. Illustrated apparatus to 10 6 will be described below · In the distance of the holding plates 8, 8 ^1, 9 and 9 'in the position as shown in Figure "1 and FIG · 6, two sets of Abbindeflügeln 27 and 28 are arranged . The upper binding wings 28 have die.Form a die in which a recess 30 is formed, while the lower wings 27 have two spring-loaded loop holder arms 37 in grooves 7o on each side, and the arms protrude upwards along the wing 27 and against each other to hold a V-shaped loop 29 made of round wire. The springs 39 form a resilient mounting for the arms 37. Each of the wings 27 has a deep, narrow recess 27b in the part of the wing between the arms 37 * The ends of the arms 37 and the upper part of the wing 27 form a substantially V -shaped recess 27d between them · The blades 27 and 28 are slidably mounted in the housing 14, and they are moved up and down according to Figs Device are connected »

The matrices. 27 and 28 also squeeze when they are actuated the V-shaped wire 29 the two ends of the stretched

90 9 8 15/0119

Hose abc To prevent the hose from sticking to the V-shaped metal tie wire 29, the guide plates 32 and 32 ', the notched groove 31 of which is narrower than the groove 30 of the upper die 28, are guided to the outside of the upper die and in equipped with a knife in the middle so that they can assume the position shown in Fig. 10 o The frame is supported by the shafts 34 and 35 so that it can move vertically up and down. The guide plates 32 and 32 'are held on both sides of the frame. The knife 19 is guided in the axial direction to the central, rear end 20 and it is usually pressed downwards by the spring 21. At the same time, the lower dies 27 and 27' are raised and to the holding plates 8, 8 'and 9, 9' through the guide plates 32 and 32 ',. As both ends of the flat film are gradually pressed so hard that they are fed to the upper dies 28 and 28 'and when the V-shaped metals 29 and 29' are closely inserted into the notched portions 30 and 30 'of the upper dies , then the lever 24 is guided downwards by means of the nooke. Subsequently, the rudiment gear engages with the rack 26 of the shaft 34 and presses the rack downward _e As a result, the frame 33 is guided downward. Then, while the knife is brought into contact with the fixed protruding part, the knife rotates forward and is guided downward. As a result, it is possible to cut exactly in the middle between the two tied off areas.

909815/0119

In the case of the lower die 27, the two side parts 37 and 37% which hold the V-shaped metal 29 can by means of the springs 39 and 39 'are guided downwards. After touching the top . Die 28 is the V-shaped metal 29 first in the longitudinal direction bent into the notched portion 30 and finally pushed down and caulked. The PiIm can, then without any damage must be connected very strongly and tightly.

The filling machine and the filling process are described below Hand of Figures 14 to 16 explained. 4-0 is the piston of the filling device, with a circular recess from the top Part leads to a suitable point. The shaft 42 inserted into the piston is intermittently driven by the gears 43 and 44 and the sector gear 45 are driven. At the same time, one end engages the pin 46 of the shaft one, while another end in the middle tol space 49 of the Swinging section 48 engages, which is connected in axial direction with the shaft 47 »The shaft is through the coupling rod moved forward and backward driven by the crank 51 moving around the pin 50. The upper opening 54 of the cylinder is connected to the hopper 1, while the lower opening 56 is connected to the injection cylinder 2. The figure represents the following operating status The piston 30 is pulled to one end of its trajectory while its recess 41 with the upper opening 54 in connection

90 98 15/0119

stands so that the material present in the funnel 1 in the Cylinder 53 is sucked in »The lower opening 56 is then covered by the lower cross section of the piston 40. The piston is driven by gears 45, 44 and 43. The upper opening 54 is closed and the lower opening 56 with the Recess 41 connected. At this moment, the piston 41 is pushed forward. The hose 2 surrounding the cylinder is then filled with the material and the filling interrupted. As mentioned above, the holding plates 9 and 9 'move and push the material aside. This filled Material is pressed so hard that the material is forced rearward near the front end of the injection cylinder and this small amount of material successively penetrates in small amounts into the space between the front end of the Injection cylinder and the hose. Therefore, if the device is operated for a long time, a significant amount of the penetrates Material so that the PiIm cannot advance smoothly and as a result, the packaging process does not proceed properly. When the piston 40 is immediately before or at the moment in that the holding plates 9 and 9 'are moved backwards, then the above-mentioned disadvantage can completely be eliminated, since in this way an empty barely can arise in the cylinder. The section of the injection cylinder 2, the comes into contact with electrode 6 of welding device B, should have a rectangular cross-section. If this Ab-

cut is tubular over its entire length, then "touched the welding electrode pulls the film along a line, so that the film cannot be welded well and often around the Tube rotates. If the cross-section 2 is rectangular, then the welding electrode is pressed onto the entire film that is attached to the surface of the rectangular cross-section is overlapped. There four there are right-angled edges, there is no risk of that the film slides off. The welding process can therefore be accurate be performed" ' .
