Below, the operation of the ligation/cutting assembly 20 with said structure is described.

Be provided with identically with continuous filling shown in Figure 13 packing, film 1 is analysed back along upper peripheral edge from the outside of cylindric formed parts 6, is guided in the tube, and like this, film 1 promptly is configured as and the corresponding to cylindrical shape of the inner surface configuration of formed parts 6.Film 1 is sent to the below continuously by the revolution of film conveying roller 12 and 13 then, with high-frequency electrode 10 and 11 deposited the peripheral part high frequency of film 1, forms film package 16 cylindraceous.By filling nozzle 5 materials such as preparative treatment meat are filled to continuously the inside of this barrel-contoured film package 16 from fix-displacement pump 4.On the 14a of boundary between muscles mechanism, make boundary between muscles roller 14 and 14 carry out intermittently crimping action repeatedly, the film package 16 that is filled with material is pressed into discontinuously flat, cause the material of inner filling to separate up and down, make tight joint between film, thereby finish the boundary between muscles action.In accompanying drawings such as Fig. 4, represent that with symbol 16a this is with the separated part of meat.

Above-mentioned ligation/cutting assembly 20 does not show up-and-down movement under the effect of the reciprocating type driver train of bright its single-piece in the drawings, and its kinematic velocity then adapts with the film package 16 above-mentioned descending speeds of separating part 16a.As shown in Figure 4, film package 16 passes through in the guide cylinder 36 of ligation/cutting assembly 20.So, when the separating part 16a and ligation/cutting assembly 20 and descend of film package 16, promptly the partitioning portion 16a in the guide cylinder 36 are carried out following ligation/cut-out work with much at one speed.

Also be, when ligation/cutting assembly 20 descends with the descending speed that adapts with film package 16, just rotary motive power is input to as shown in Figure 5 input shaft 23 and 31, by input shaft 23 and 31 and with the revolution of its all-in-one- piece transmission arm 25,33, when moving in the position that driven roller 26 and 34 is represented with long and short dash line in Fig. 5, the movable block 27 in left side just moves to graphic dextrad, and meanwhile, the movable block 35 on right side just moves to graphic left-hand.

Towards the initial period that mutual direction of closing moves, converging member 41 and ligation metal paattern 43,44 on the left of being fixed on the movable block 27 and the metal wool cut- out member 46,47 that is fixed on the maintainance block 48 move in the pilot hole 65a of orienting lug shown in Figure 6 65 at two movable blocks 27 and 35.At this moment, be in by the effect of spring 57 by pressure arm 56 and move towards power-assisted state along cw, briquetting 56a contacts with the back of maintainance block 48.Therefore, movable block 27 is moved, make converging member fixed thereon 41 when graphic dextrad moves, maintainance block 48 with regard to be in the state that is locked in by briquetting 56a effect on the movable block 27, remain on make on the maintainance block 48 cut off up and down member 46 and 47 with the immovable state of the relative position of converging member 41 under march forward.

At this moment, metal wool W, the W of aluminum is sent in the metal wool supply hole 65d and 65e that forms on the orienting lug 65, by the blade 46c of progressive cut-out member 46,47 and stationary knife spare 65b, the 65c of 47c and orienting lug 65 metal wool W, W cut off.State before Figure 11 (A) expression metal wool W is cut off.And, at this moment, axle 69 is rotated to anticlockwise direction because the effect of driving link rod 73 shown in Figure 7 makes axle 68 cws in the orienting lug 65 move towards to rotate, top plush copper 76 is then relative with the place ahead of each metal wool W, W with bottom plush copper 77.Thus, shown in Figure 11 (A) and Figure 11 (B), in the time of in plush copper 76,77 enters into the groove 46d of progressive cut-out member 46 and 47 and 47d, the metal wool W, the W that have cut off are just curved U word shape, curve metal wool W, W for U word shape and then remain in sliding tray 46a, 47 a that cut off member 46,47 [(with reference to Figure 11 (B)].After metal wool W, W were curved the U word state, by the effect of driving link rod 73 shown in Figure 7, plate gear 72 promptly moved towards to rotate along cw, moves towards to rotate towards inhour and make with this plate gear 72 ingear plate gears 71.Thus, axle 68 and axle 69 rotate mutually in the opposite direction, and plush copper 76 and 77 is just deviate from from the moving area that cuts off member 46,47 etc.

As shown in Figure 9, when sway piece 27 and 35 each other further near the time, bring together groove 41e and the right side of bringing together on plate 41b, the 41c with left side converging member 41 front ends are brought together and are brought groove 93d together on plate 93a, the 93b, make to have become flat separated part 16a to bring together on the film package 16.When sway piece 27 and 35 further near the time because the mobile thrust of two movable blocks supporting the sleeve 92,92 of bringing plate 93a, 93b together in the right side spring 94,94 is shunk, the axis of guide 91,91 is slided towards the right side.

When this two movable block 27 and 35 more further near the time, the front end that is fixed on the maintainance block 48 in order to the axis of guide 91,91 on the front end of the axle 61,61 of the position of determining to contact and right side just joins as shown in figure 10, at this moment, rising by the contact surface of roller follower shown in Figure 4 59 and plane template 29a, by transmission arm 58 and axle 55, make by pressure arm 56 and move towards revolution, and use shown in the long and short dash line, briquetting 56a is thrown off from the back of maintainance block 48 as Fig. 5 along inhour.Thus, on being fixed on maintainance block 48, be used for determining contacting the axle 61,61 of position with after the axis of guide 91,91 contacts, maintainance block 48 and metal wool fixed thereon cut off moving of member 46,47 and just are restricted, after this, movable block 27 is in right-hand moving, spring 52,52 is shunk, and the axis of guide 49,49 that is fixed on the maintainance block 48 promptly slide in the bearing on movable block 27 51,51.

Thereby, on the preceding end in contact of the axle 61,61 of the position that is used for determining contacting and the axis of guide 91,91 after, the metal wool cut-out member 46 and 47 that is fixed on the maintainance block 48 does not move out from this position; Ligation metal paattern 43 and 44 guiding protuberance 43e and 44e then slide in metal wool cuts off chute 46a, the 47a of member 46,47, groove 43g, 44g on these two metal paattern front ends just becomes metal wool W, the W of U word shape Face to face to clamp with groove 96a, the 97a of right side metal paattern 96,97, and shown in Figure 11 (c), make metal wool W, W be deformed into the shape of metal wire clamp 3, on two positions, film 1 is clamped.As shown in Figure 3, because at this moment the sweep of metal wool W, W is engaged in little groove 43h, the 44h that forms on the groove 43g, 44g bottom surface of ligation metal paattern 43 and 44, therefore, when carrying out the clamp operation of metal wool W, W, the metal wool revolution of just can not skidding, and available metal line W, the W film 1 of tying tight securely forms metal clip 3 on upper and lower two positions.Here, there is no particular limitation for the shape of little groove 43h, 44h, for example can be aspect arbitrarily such as slit-shaped, polygon, circle, ellipse, the degree of depth be about 0.5mm, if metal W, W when tying tight, can snap into the Any shape that can't skid in the metal paattern partly can.

At two movable blocks 27 and 35 approaching mutually, each groove 43g, 44g and 96a, 97a on ligation metal paattern 43,44 and the metal paattern 96,97 dock fully, carry out before the tying tight of metal wool W, W, as shown in Figure 4, roller 106 is contacted with block 107, by movable block 35 moving and make transmission arm 103 move towards rotation towards left-hand along cw, and tool bearing platform 101 is moved to the diagram left-hand, as shown in figure 10, cutter 100 is driven into the position that punctures film 1 always, in the middle of folder 3,3 parts that form by metal wool W, W, cuts off film 1 again.

After above-mentioned ligation/cut-out work is finished,, make movable block 27 and 35 towards the direction motion of leaving mutually by the revolution of input shaft shown in Figure 5 23 and 31.After axle 61,61 axis of guides 91,91 from the right side that are fixed on the position that is used for determining on the maintainance block 48 in left side contacting leave, metal wool cuts off member 46,47 and ligation metal paattern 43,44 just returns towards the diagram left-hand, makes the relative position between them become state shown in Figure 2.At this moment, driving link rod 73 shown in Figure 7 is driven towards graphic dextrad, axle 68 moves towards to rotate towards inhour, and axle 69 moves towards to rotate towards cw.So the plush copper back-up block 74 of upside shown in Figure 8 just move towards revolution according to inhour, because the elastic force of spring 82, sleeve 78 promptly move towards to rotate along inhour, and by the elastic force of spring 82, make detection pin 79a by be pressed in metal wool cut-out member 46 above.The plush copper back-up block 75 of downside is docile and obedient hour hands and is moved towards revolution, and it is the effect by spring 89 also, pushes sleeve 85 towards the cw trend, the detection pin 86a that makes downside by be pressed in metal wool cut off member 47 below.

When above-mentioned metal wool cut- out member 46 and 47 is returned to position shown in Figure 2, as above said, acceptance has the detection pin 79a and the 86a of spring 82 and 89 elastic force, and just detection hole 46e, the 47e that cuts off member 46,47 from metal wool enters into each ligation metal paattern 43,44 and tie tight in groove 43g, the 44g of usefulness.This state is shown by the dotted line among Fig. 2.When detecting pin 79a and 86a and enter in groove 43g, the 44g,, therefore just can be detected by non-contact switch 83 and 88 because upper and lower each check-out console 81 shown in Figure 8 and 87 moves with detecting pin 79a, 86a.

Also promptly,, just can detect metal wool W, W and not have leftly in groove 43g, the 44g of each ligation metal paattern 43,44, enter fully in groove 43g, the 44g but detect pin 79a, 86a when detect when output from non-contact switch 83 and 88.On the contrary, among groove 44g, the 43g of the ligation metal paattern 43,44 that is returning when metal wool W, W are left at least one groove the time, then detect and have at least one not enter in groove 43g, the 44g among pin 79a, the 86a, the place in non-contact switch 83,88 is just detected less than output so at least.

When learning the failure-free ligation of tying tight and forming by metal wool W, W that to carry out shown in Figure 11 (C) in by above-mentioned detecting operation, and metal wool W, W are left when 43,44 li of ligation metal paattern, can interrupt this operation, so just can prevent that metal wool W, the W from cutting off once more.

When the fastening finishes, and the movable block 27 in left side is when graphic left-hand moves, when maintainance block 48 under the effect of pressure spring 52 and towards dextrad shown in Figure 4 when afterburning, movable block 27 and converging member 41 fixed thereon just return to graphic left in advance.At this moment, be docile and obedient by spring 57 effect hour hands move towards the application of force by pressure arm 56 just under the effect of the power that this spring 57 is executed, revert to the state of representing with solid line on Fig. 5.

When carrying out repeatedly owing to above-mentioned ligation/rupturing operation making groove 43g, the 44g wearing and tearing of ligation metal paattern 43,44, cut off member 46,47 by unloading metal wool illustrated in figures 1 and 2, and bolt 45 lemon pines, just can unload ligation metal paattern 43,44, change from converging member 41.At this moment, also can unload converging member 41, but still can change not unloading under the situation from movable block 27.Also can only change the metal die holder 95 on right side.

As shown in Figure 4, in the above-described embodiment, be on tool bearing platform 101, to connect transmission arm 103, contact with block 107 by the roller 106 that on this transmission arm 103, is being provided with, just can drive tool bearing platform 101 by transmission arm 103, direction is outstanding left and make cutter 100.But, carrying out ligation from metal wool W, W are tied tight and form wire clamp 3 to film 1 being cut off with cutter 100, the time gap in the middle of this is quite short, it is quite difficult carrying out adjusting work.Thereby, also can drive tool bearing platform 101 by cylinder mechanism etc., so that after finishing ligation work, can have that chien shih cutter 100 advances when fully more than needed, film 1 is cut off.

When utilization forms above-mentioned little groove or small embossment on ligation metal paattern 43,44 apparatus for ligating of the present invention is made film package 16, on its outside face of metal wire clamp 3, just have with the corresponding projection of little groove or with the corresponding groove of small embossment.

Form protuberance or groove on the inside face of the groove by the usefulness of tying tight at metal paattern, can when metal wool is tied tight, prevent that metal wool from skidding in metal paattern, thereby can carry out firm ligation work.

Owing to converging member and metal paattern are made separable, carry out repeatedly and when making the metal paattern wearing and tearing in the ligation operation, can unload metal paattern from converging member, change, just needn't change does not thus also have the worn-down converging member.And can also under converging member still is installed in situation on the device, change metal paattern, it is easy therefore more changing jobs.

Because metal paattern is correctly to be positioned on the converging member by concavo-convex cooperation, thereby can improve the relative positional accuracy between converging member and the metal paattern; Also utilize bolt, thereby just can change metal paattern easily by operation to this bolt owing to metal paattern.

Integrally be shaped by the guiding protuberance that makes metal wool cut off member and slip,, like this, just can make and bring the simple in structure of plate together so the mechanism that member is cut off in guiding needn't be set on converging member.
