Definitions

  • the invention relates to a clip machine with at least one closing lever according to the preamble of claim 1.
  • the filling material is introduced into a tubular casing (intestine) and then divided in portions in a first cycle by means of displacement elements.
  • the displacement elements lace the tubular casing in radial direction Direction and displace the filling material located in the constriction in the axial direction - relative to the tube axis.
  • a Schlauchzopf is formed.
  • one or optionally two closure elements (clips) are applied by means of two (or four) against each other moving closure tools and closed around the hose plait in the next cycle.
  • the closing tools each comprise in pairs a punch and a die, between which the clip is deformed during the closing.
  • double clip assembly the hose plait can be severed by means of a knife in between to separate the sausages. Thereafter, the displacers, closing tools and the knife are moved back to their initial or open position.
  • One working cycle is over.
  • the following description is related to the simple arrangement of a pair of sealing tools. However, it can be easily transferred to a double clip arrangement.
  • At least one of the closing tools is attached to the closing lever described above and executes during the closing operation a - relative to the tube axis - substantially radial pivoting movement about the pivot axis.
  • the closing lever with closing tool is brought into a pivoting movement or a linear movement or an overlay of two forms of movement with the first closing tool for closing the clip or ,
  • a cam drive is usually available which decreases the movement of the closing lever by means of a cam roller from a cam disc.
  • a lever arrangement is typically provided which transmits this movement to the closing lever.
  • a linear fluid drive typically a pneumatic drive.
  • Object of the present invention is to improve a machine of the type mentioned in that the efficiency of the clip machine can be increased without higher drive design.
  • the closing levers were manufactured in a known manner from cast aluminum. In addition to the disadvantages described above, this also means that the bearing element, receiving element and force introduction element as well as other functional elements such as curves or running surfaces and mounting points can only be manufactured by reworking with the necessary precision on the casting. In contrast, the closure lever made of fiber-plastic composite (FKV) in one completely ready for use.
  • FKV fiber-plastic composite
  • the moment of inertia of the closing lever can be reduced by at least while maintaining and sometimes even improving the mechanical strength by about 30%.
  • This causes all drive elements dimensioned smaller and lighter to a corresponding extent and reduces the cost of the entire clip machine and the operating speed of the clip machine can be increased with constant dimensioning of the drive elements.
  • Also causes the use of a FRP material due to other resonant properties that the sudden closure movement of the closing tools undergoes an acoustic damping, whereby the closing process is only an insignificant acoustic burden on the serving staff.
  • the use of a FKV material, and in particular the use of CFRP advantageously proves to be food compatible, sterilizable, temperature resistant, chemical resistant (especially detergent resistant) and high pressure resistant.
  • the surface of the closing lever made of FRP material according to the invention is smooth per se. As a result, a further post-processing operation can be saved without disregarding the hygiene conditions to be observed in the area of food processing.
  • FIG. 1 shown embodiment of the clip machine 100 comprises a clip machine drive 110 with a cam 112, by means of a cam roller 116, the movement for a lower locking lever or clip lever 118 is removed. Furthermore, the clip machine has a further clipping machine drive with a crank 130, from which the movement for an upper closing lever or clip lever 120 is removed by means of a lever arm 114.
  • both closing levers 118, 120 are pivotably articulated about the same pivot axis 122.
  • the lower clip lever 118 carries at its end remote from the pivot axis 122, a first closing tool 124, which is a die in the embodiment shown.
  • the upper clip lever 120 carries at its end opposite the pivot axis 122 a second closing tool 126, which is a punch here.
  • the lower locking lever 118 pivots driven via a lower toggle assembly as a drive element about the common pivot axis 122 upwards when the toggle joint of the lower toggle lever is stretched by a force introduced via a coupling rod force.
  • the upper clip lever 120 pivots about the common pivot axis 122 driven via an upper toggle lever arrangement as a drive element down when the knee joint of the upper toggle lever assembly is stretched by a force introduced via a coupling rod force.
  • the die 124 and the punch 126 are moved toward each other in order to close in its closed position a clip to the previously constricted tubular casing (not shown) can.
  • a pulse triggers the actuation of a cylinder-piston arrangement which, in the case of the double-clip arrangement present here, drives a knife in order to sever the hose pledget between the two closed clips. Thereafter, the upper and lower Verschwinhebel 118, 120 pivot back into their open positions.
  • both closure levers 118, 120 must have very high strength.
  • both levers must perform a sufficiently large pivoting movement, so that large sausage caliber during the filling in a to the in Fig. 1 plane shown vertical movement direction between the Verschierwerkmaschineen 124, 126 can be conveyed through.
  • a sufficient strength with still relatively low weight and thus a low moment of inertia about the pivot axis 122 provides the lower locking lever 118 according to the invention when it is at least partially made of a fiber-plastic composite.
  • FIG. 2 an embodiment of such a lower Verschwinhebels 200 is shown in side view; which is not part of the invention.
  • This has a main body 210, which extends substantially in the display plane.
  • a bearing element 212 which has a first metallic bearing receptacle includes.
  • This bearing mount has anti-rotation, for example in the form of notches or projections, which prevent the bearing member 212 is rotated in the FKV material.
  • a receiving element 214 for positioning and holding the first closing tool (s) and a force introduction element 216 for connection to the drive element are embedded in the main body 210. Both the receiving element 214 and the force introduction element 216 are preferably embedded in the base body 210 in the form of a metal insert.
  • the base body has clearances 218, by means of which the weight of the closing lever 200 is reduced, but without falling below the predetermined stability limit of the closing lever.
  • Openings shown in Figures 218 may also include apertures which are not perforated, in similar or different configurations, which possibly conduct the power flow differently, but also with the requirement of sufficient stability.
  • the embodiment of the lower Verschwinhebels according to Fig. 3 shows in the perspective view that in addition to the main body 310 and a cranked arm 312 is still provided, which is connected at one end to the base body 310.
  • the bent cantilever arm 312 thus protrudes out of the plane defined by the main body 310.
  • the bearing element 322 consists of a metallic bearing receptacle 324, which is embedded in the main body 310 from one side, so that the first bearing receptacle 324 protrudes from the plane of the main body 310 on the side opposite the bent arm 312.
  • the bearing element 322 consists of a second metal bearing receptacle 326, which is inserted coaxially with the first metal bearing receptacle 324 in the cranked arm 312.
  • the bearing can be made over such a long axial section that the closing lever withstands greater bending moments in the axial direction.
  • the insertion of the inserts takes place in the method for producing such a clip lever, for example in the preform RTM manufacturing process, by inserting the bearing element 212, 322 of the receiving element 214, and the force introduction element 216 in a mold, in which further the base body 210, 310 and optionally the cantilever arm 312 of layers of preformed fiber mats, a carbon fiber fabric, built up in layers. Subsequently, the mold is closed and it is a liquid plastic (for example, epoxy resin) injected under high pressure into the mold until it is filled. After curing of the plastic, the mold can be opened and the finished closing lever 200, 300 are removed. The inserts go through the cured plastic a positive connection with the stabilizing fiber mats. How the stability of the positive connection can be increased, can be inferred from the embodiment in the exploded view in Fig. 4 explain in more detail.
