Description

The present invention relates to a cutting machine a cutting knife, an adjustable stop, a moved back and forth along the knife plane Cutting material slide, a cutting material feed device for the cyclical feed of the material to be cut towards the Stop after each cut, a first adjusting device for setting the stop depending on the desired cutting thickness and a second adjusting device for setting the feed path of the material to be cut on the Sledge depending on the desired Cutting thickness at every feed cycle.

DE 41 10 526 (A1) describes a cutting machine with a automatic material feed and one by one motor drive back and forth along the knife level moving sledge known. These cutting machines are also known as automatic cutters. At a Automatic cutters perform the back and forth movement of the Cutting material sled motor and the cyclical feed of the Cutting material after each cut is also done automatically, so that one item to be cut is practically completely one after the other can be cut open.

There are also cutting machines where the Carriage must be moved by hand to get the cut through to guide the knife level. With the latter Handling cutting machines is often quite cumbersome. This is partly due to the fact that to protect the Operator in the area facing this hand protection is prescribed on the knife side prevents the operator from reaching into the knife. On the other hand, the operator must cut the material to be cut Often cut by hand to keep a clean To achieve a cut, especially this applies to shorter ones Material to be sliced that has already been cut open relatively far. Here the hand protection mentioned can be a hindrance and the Handling the machine when cutting shorter material to be cut to become cumbersome.

There is therefore a need for cutting machines with from Hand or automatically moved back and forth Cutting sledge, which is cycled after each cut Feed the material to be cut towards the knife accomplished. In the known cutting machine mentioned above with a motor-driven slide, which is described in DE 41 10 526 (A1) is a spindle for the feed provided which is driven by a gear which in a rack that can be moved relative to the sled intervenes. The disadvantage of this cutting machine is that due to the division of the gear the setting for the feed path of the cyclical feed of the material to be cut is almost always only possible in small steps, whereby when adjusting the desired feed path via the The gear always after each feed step so that it engages the rack. Thereby Depending on the setting, the actual feed path of It varies from measure to measure and therefore does not always correspond to that set feed path. This can lead to especially soft material to be cut more or less strongly the knife is pressed and thus despite evenly set feed the weight of the one after the other cut slices vary depending on the pressing.

In addition, in this known cutting machine Mechanism for the transfer of the set Feed paths to the actually effected feed right complicated because a first actuator for the Stop plate includes a cam track with a cam and the second actuator for effecting the intermittent feed includes yet another cam track.

The mechanism known from this machine for the intermittent feed of the material to be cut can be due to the mentioned disadvantages not in a meaningful way on a Cutting machine with hand to and fro Transfer the cutting sledge.

The object of the present invention is a Manual cutting machine of the type mentioned at the beginning or automatically move the product sledge back and forth create a cyclical feed of the material to be cut guaranteed every cut and thereby a correspondence of set cutting thickness and the feed path for the intermittent feed is ensured. At the same time this cutting machine is relatively simple be.

The solution to this problem was provided by an inventive one Cutting machine of the type mentioned with the characterizing features of the main claim or with the Features of claim 2.

According to the invention, the device for the clockwise Feed the material to be cut after each cut Clamping device which is arranged on a linkage which executes a stroke with each cyclical feed and the Takes clamping device. Moves with every return stroke however the linkage without the clamping device in Starting position back while the clamping device in remains in place. Characterized in that with the clamping device a thrust element for feeding the material to be cut is connected is this moves cyclically with the clamping device after each cut and pushes the material to be cut cyclically in the direction of the knife level. The Actuator for setting the stop, which the determines the respective cutting thickness, is connected to a Bar block with a ramp on the one with the Slide movable element with the aforementioned Linkage is accrued after each cut, so that this movable element has a stroke corresponding to the set cutting thickness in the axial direction of the boom accomplished. In the solution according to the invention, that is first adjusting device for setting the stop with the second adjusting device for setting the feed path (Clock block with ramp).

The particular advantage of the invention is that when adjusting the cutting thickness, the stop moved is and with this stop the clock block at the same time the run-up slope is shifted. So you determine the Stroke of the boom and at the same time the feed path of the Clamping device at every cycle. This means that the Feed path with every cyclical feed of the material to be cut exactly in sync with the set cutting thickness is adjustable and infinitely variable without the division of a gearbox must be taken into account. In addition, the whole mechanism works without cams etc. and is solved structurally much easier than with the known from the prior art Cutting machine.

At the same time, the cutting machine according to the invention has the Advantage that after each cut a cyclical feed of the Cutting material is done. The operator inserts the one variant of the invention differently than one Automatic cutters must slide the carriage back and forth by hand but not every time like with the usual machines Push the material to be cut and align if necessary. This will make the Handling of the cutting machine made considerably easier and the cutting material can be cut open more quickly. In the second variant of the invention, both the Feed of the material to be cut as well as the back and forth movement of the product carriage automatically.

In a preferred constructive solution, this is done Linkage arranged under the carriage so that it out consists of two parallel rods that are connected to one arm are interconnected. With one part of the boom you can then connect the element that is on the slope of the Clock blocks runs up and on the other linkage, that too is arranged in parallel, you can use the clamping device attach. It is further preferred that the element that an impeller runs onto the slope. This impeller can are located, for example, on the end of one linkage. Preferably are for both rods Guide devices provided through which the linkage at axial stroke is guided, the guide devices are preferably attached on the underside of the slide.

The adjusting device for adjusting the cutting thickness can for example, a setting wheel or the like. In the Adjustment of this setting wheel is preferably the Adjusted the stop plate, which acts as a knife-side stop for the material to be sliced is used and preferably at the same time connected to the stop plate in the lower area on the Clock slope located ramp is also adjusted in such a way that the stroke of the boom is synchronized with the set cutting thickness changed.

The clamping device is preferably on the underside of the Arranged slides and around the cyclical feed movement the clamping device on the movement of the device for the Feed of the material to be cut is to be transferred Clamping device preferably with a vertically upward protruding arm connected, which in turn with a tub in the the material to be cut lies and / or with the rest holder for the Feed of leftovers or shorter pieces to be cut communicates. Usually you go as follows. A longer product to be cut is on this Tub placed so that it is in its front too cutting area in the direction of the knife level above the Trough protrudes and it is preferably the material to be cut from clamped at the top with the remnant holder. The tub moves then with the remnant holder in cycles after each cut Direction to the knife level. The tub is above the slide and moves in after each cut this direction to the knife level relative to the carriage. At the same time, the tub, leftovers and Clamping device with the slide parallel along the Knife level so that the jammed clippings are cut and they move in with every cut an execution and move back after each cut in a starting position. That way you can Cut the material to be cut until the pan has advanced so far is that it is just before the knife level. In this Position is provided a stop that the machine stops. An operator can then carry out the tub and the rest holder move back away from the knife level, the material to be cut, which is now shorter, insert again and a plate of the Place the rest holder behind the material to be cut so that it is then is no longer clamped from above, but from the back clockwise in the direction of the knife level pushed and thus completely cut open.

According to a preferred development, the axial Movement of the boom against the force with every stroke at least one feather. This spring causes the return stroke of the Linkage when the impeller is out of engagement with the Sloping ramp arrives. The linkage moves like this The clamping device was already executed above does not participate in this return movement but remains in their advanced position and will at the next Feed movement advanced again a bit.

The features mentioned in the subclaims relate to preferred developments of the two according to the invention Task solutions. Further advantages of the invention result from the detailed description below.

Since in one variant of the invention Cutting machine the mechanism described above after each Cut a feed movement of the material to be cut in the direction the knife triggers, the operator should go back and forth However, moving by hand ensure that after each If possible, cut the sled back into the front of the Operator facing starting position withdrawn is to ensure that the mechanism with the Impeller and the ramp are actually working Fulfills. With a short back and forth movement of the Sled, which is theoretically possible with narrow material to be cut there would be a risk that the impeller would not be on the Accelerated bevel runs up and therefore no after the cut Feed is triggered.

First, reference is made to FIG. 1.
The illustration shows a carriage for receiving the material to be cut, which is designated overall by 10. This carriage 10 was removed from the cutting machine. As can be seen, the carriage 10 has a trough shape with an approximately U-shaped cross section in the area of the receptacle. The carriage 10 has a left side wall 11 and a right side wall 12, these being connected via a carriage bottom 13. The left side wall 11 has an upper horizontal projection which projects outwards, so that a horizontal web 14 results, from which in turn a molded-on vertical web 15, which is angled downwards at right angles, points downwards. The left side wall 11, the upper horizontal web 14 and the vertical web 15 result in a U-shaped unit which is open towards the bottom. The right side wall 12 has an elongated cutout 16 in the central region.

2, which corresponds to that in FIG. 1 shown slide 10 shows from below. On the bottom of the carriage 10 is the facial expressions for the intermittent feed of the material to be cut in the automatic Cutting the material to be cut is required, taking this on the underside of the carriage 10 attached parts with a longitudinally movable on the slide on the machine side Clamping device 30 cooperates, which is shown in Fig. 4 5 and 6 is shown. In addition, the device works for the intermittent feed of the material to be cut on the underside of the Carriage together with the clock block 40, which is dash-dotted is also shown in Fig. 4 and 4a and to which the Carriage 10 is movable transversely, corresponding to the back and forth Movement of the carriage 10 during the cutting process according to the arrows shown in Fig. 4, while the feed movement of the clamping device 30 in connection with the product holder in the direction of the knife axis in the direction of arrow 31 in FIG. 4.

Reference is first made to FIG. 2 and the facial expressions described for the cyclical advance of the material to be cut located on the underside of the carriage 10. This Device comprises a rotatably mounted impeller 17 which a kind of block 18 is attached. From this block 18 a first linkage 19 goes in the axial direction is slidably mounted against the force of a spring 20. As Guide device for the linkage 19 is used Guide block 21. The other end of linkage 19 is on a connecting arm or on a connecting plate 22 attached to its other end with a second Linkage 23 is connected. This second linkage 23 runs parallel to the first linkage 19 and is at its in the Drawing according to Fig. 2 right end with the connecting plate 22 connected so that the two linkages 19, 23 and Connection plate 22 a related form about a U-shaped unit. Also for the second linkage 23 is a guide block 24 as a guide device provided and this second linkage 23 is against the Force of a return spring 25 axially slidably mounted. The in the drawing left end of the linkage 23 is in one guided further guide block 26.

In the side view of the carriage 10 according to FIG. 3, one can once again the essential parts of this facial expression, namely that Impeller 17, the linkage 19, the guide block 21 and the Recognize connection plate 22, which is under the carriage 10 are located.

Reference is now made to FIG. 4 below. From the Drawing, which in turn is a bottom view of the sled shows, one can now arrange the machine side Recognize clamping device 30 with that previously described Device for intermittent feeding of the product holder cooperates. This clamping device 30 sits on the Linkage 23, which was carried out as above Connection plate (arm) 22 is connected to the linkage 19. The clamping device 30 is designed so that it in a direction of movement allows the passage of the linkage 23 and in the opposite direction the passage of the linkage 23 is locked, so that in the opposite direction, the clamping device 30 one piece moved with the linkage 23. 5 and 6 is the Clamping device 30 shown again enlarged in two different settings. Based on this Figures, the clamping device will be closer below explained.

First, the function of the clockwise Feeds explained with reference to FIG. 4. If the sled 10 4 parallel to the plane of the Knife 28 moves upward, then the impeller 17 runs after setting the material thickness earlier (thicker Slices) or later (thinner slices) on the slope 29 clock block 40. This moves the impeller 17 and with this the linkage 19, the connecting plate 22 and also the linkage 23 in the drawing of FIG. 4 to the left, the springs 20, 25 designed as return springs be compressed. The linkages 19, 23 perform one Axial movement to the left and are on the slide in the Guide blocks 21, 24, 26 guided. Because of the setting the clamping device 30 is this movement of the Linkage 23 to the left according to its stroke a bit taken along, which creates a cyclical feed, because in the return movement caused by the springs 20, 25 of the linkage 19, 23, which is possible if the impeller 17th is again out of engagement with the clock block 40, moves the linkage 23 in the drawing right again in his Starting position. But the clamping device 30 is so set that this return movement of the linkage 23 free is, so that the clamping device 30 is not taken along but maintains its position. The left position after the stroke of the linkage 19 is shown in Fig. 4a. The Feed movement of the clamping device 30 corresponds exactly to that Gap between stop 31 and knife 28 and thus the desired cutting thickness.

The clamping device 30 thus pushes cyclically with each Back and forth movement of the carriage 10 by a piece on the Knife level of the knife 28 too wide.

The mode of operation of the clamping device 30 can be seen from 5 explain. This shows the clamping device 30 in a shot of the passage of the boom 23 to the right without the clamping device 30th is taken, when when the linkage 23 after the clamping device moves to the left over the clamping stone 132 wedged on the linkage 23. This happens through the Edge pressure of the linkage 23 in the bore 132a in the Clamping stone 132, which results from the fact that the clamping stone 132nd is not at right angles but at an angle to the linkage 23. 5 therefore shows the clamping device 30 in its Active position.

In contrast, in FIG. 6 the clamping device 30 is in its neutral position, in which the passage of the Linkage 23 allows in both directions because of the clamp 132 is now perpendicular to the linkage 23. The change from 5 into that according to FIG. 6 happens in that on the switching device 134 Swivel movement by 90 ° C counterclockwise becomes. Thereby, the switching device 134 expresses how to Fig. 6 recognizes the articulated arm 135, the again against the upper angled leg 136 of the Angle part 133 presses and this angle part 133 to a short swivel motion counterclockwise around his Swivel axis 137 causes in which it is mounted. This Angle part then moves the clamp 132 out of its 5 in the position shown in FIG. 6, in which is perpendicular to the linkage 23 and the bore 132a the passage of the linkage 23 in both directions enables.

The function of the automatic intermittent feed of the Cutting material through the knife level after each cut is now with reference to the two drawings FIGS. 7 and 8 described in more detail. This can already be seen in FIG. 4 clock block 40 shown in the left portion of Fig. 8, the is under the carriage 10 and the one Stop plate 31 is connected, which via a setting wheel 42 in 8 adjustable to the right or left is. With this setting wheel 42, the stroke can be done with everyone intermittent feed and thus the slice thickness cut is set, since clock block 40 is also adjusted (see also Fig. 4) and thus the stroke, perform the impeller 17 and the linkages 19 and 23 changed. 8 also shows that under the carriage located arm (connecting plate) 22 with the linkage 19 is connected, which in the guide blocks 21 u. a. guided becomes.

8, the clamping device 30 can also be seen and one can see in connection with Fig. 7 that this over a vertical arm 32 with an approximately U-shaped trough 33 is connected, in which the material to be cut 34 lies. Because this tub is clamped to the arm 32, it moves with this in cycles after each step through the Knife level of the cutting knife 28. This cutting knife 28 is shown in Fig. 7. The tub 33 is in the carriage 10 and moves relative to the carriage 10 after each cutting cycle on the cutting knife 28 to. On the other hand, the entire slide 10 also moves together with the tub 33 along the knife plane at each Cutting process back and forth once. Above the tub 33 is as can be seen from FIG. 7, the residue holder 35 for the material to be cut, in a manner known per se can be trained. The residue holder 35 is so with Arm 32 connected and also moves after each cut cyclically forward in the direction of the arrow in FIG. 8, so that the Material to be cut 34 (see FIG. 7) step by step after each cut a piece is moved towards the knife level.

The advantage of the invention is that the facial expressions for the intermittent feed (see above Fig. 4 and Fig. 4a) by the impeller 17 running on the slope 29 after each cut forcibly causes the feed. It is advantageous that via the adjusting wheel 42, the position of the clock block 40, the Stop plate 31 and the slope 29 to the impeller is continuously adjustable and therefore also the stroke that the linkage 19, 23 with the clamping device 30 and the arm 32 continuously changed with each feed can be. As a result, the settings are fine desired slice thickness when cutting the material to be cut possible, the set slice thickness actually always corresponds to the desired slice thickness.

The stroke of the linkage 19, 23 and the different Arm 22 and clamp 30 settings once with the impeller 17 running onto the slope 29 and to other if the impeller 17 is out of engagement with the slope 29 quasi in a zero position result from Comparison of FIGS. 4 and 4a.
