ⁿ holding device for knife or the like.

on cutting devices for wood ", or the like. ^!!

The innovation relates to a holding device for knives or the like on cutting devices for wood or the like »

In the previously known cutting devices for wood or Eol products, the individual knives are od.'dgl by means of screws. detachably attached to a rotating or stationary knife basket. This has the major disadvantage _s that when replacing blunt or damaged knives, the position of the new knife basket must be set up again »

D5.e The knives are set in a laborious manner by turning the knife cage _3, which requires tedious work and, in an undesirable manner, results in a long service life of the cutting device.

The object of the! Inflation is ₅ while avoiding the previous disadvantages to provide a holding device for knives _s which allows fast and easy replacement of the cutting tools to chipping mechanisms with a simple design.

According to the Heuerung a holding device for knife to chipping mechanisms for wood or the like "by a fixable to a knife basket of a machining apparatus knife holder is _s as cold plate od.dgI in ;, where veränderbar'festgelegt''Ist a knife detachably and positionally .. . . .

In a preferred embodiment, the knife can by means of Screws or the like be releasably attached to the retaining plate and the retaining plate can be fitted with receiving openings for fastening screws as well as fixing devices for arranging on the knife he basket- ' Equip: -as fixing devices can -on the holding plate Fisierbohrungen and / or fixing zap fen.;, Pins or the like. intended his »■ -.- '..'" .-. "~", _

In a further feature of the innovation is a device for positional adjustment of a blade to the holder by a fixing means in the blade holder receiving means and manipulated, as well as measuring devices for determining position of the knife-equipped base plate is in _s

Further features of the innovation can be seen from the others Subclaims.

The object of Heuerung.erstreckt look not only on the characteristics of each claim _s but also to their combination "-

The innovation is characterized by a simple structure, "easy production and favorable mode of operation" and "handling" ο

It is particularly advantageous ₉ that at a knife basket to be fixed knife on a holding plate (knife holder) positionally fixed and are arranged with this retaining plate in a simple and rapid manner to the knife basket ", due to the previous determination of the diameter to the holding plate and the means of centering The arrangement of the saw device, which can also be fixed in terms of its position on the knife basket, is always the desired knife position: on the knife basket , and subsequent setting up of the knife is avoided.

The knives can be changed in a very short time ₉ so that laborious work and long downtimes of the cutting devices are no longer necessary. "-.

The setting of the knife in a position to the holding device is constructed in a favorable manner in a simple and easy _s made-to-device so that the dull or damaged blade after recovery in the setting device for later use can be set already in the machining apparatus "

Such a holding device extends in its arrangement not only to the cutting _{devices 5} but can also be used in other cutting devices or machines.

In the drawing is an embodiment of the innovation shown. Show it :.-.-.

In the middle area of the holding plate 11, for example, two are arranged parallel to one another and at a distance (at right angles) to the longitudinal direction of the plate. . Receiving openings Ik ₉ . preferably elongated holes or the like. elaborated, through each of which a fastening screw 13 grasps and grasps threaded bores 15 worked out in the knife 12 in accordance with the receiving opening arrangement. The knife 12 has at least two threaded bores 15 _s but can preferably be equipped with a plurality of threaded bores 15 arranged at a distance from one another and one behind the other, so that in addition to the displacement arrangement of the knife 12 on the holding plate 11, due to the elongated holes l4, a further possibility of fastening the knife 12 on the holding plate 11 from wear due to repeated sharpening or the like. ■. "'.

In each of the two rare areas of the holding plate 11 there is a receiving opening 16 _s, for example a semicircular ₃ recess or the like open to one side (towards the cutting edge 17 of the knife 12). provided, in the fastening screws l8 or the like. To fix the holding device Io, enclose a knife basket (knife yields ^) 19 of the cutting device 2o.

in each case a pressed-in fitting bushing 22 ″ which, for example, partially protrudes ₉ from the plate plane on the knife side. Instead of the fixing hole 21, the holding plate 11 can also be equipped with fixing pins, pegs or the like, as well as bores and pegs

For example, rectangular in its basic form knife 12 is in its length less than the distance provided for in the side regions receiving openings 16 and thus fixation holes 21 to each other ausgeführt- _s. so that the receiving openings l6 and fixing bores 21 extend outside the extent of the knife.

The receiving openings '16' and fixing bores 21, which are each arranged in a side area of the holding plate 11, are preferably on a common _{plane s} , the receiving openings 16 being provided adjacent to the cutting edge 17 of the knife and the fixing bores 21 being provided opposite the knife cutting edge. ■■ .-.

The Hesserkorb 19 is provided as a rotating body and is arranged in the mouth area of a feed channel 2V with its knives 12 attached to several holding devices Io, so that the supplied wooden parts or the like are cut by its knives 12 when the Iesserkorb.es 19 rotates . The chips can then pass between the adjacent knives 12 in a suction channel 25. The thickness of the chips is determined by the “knife 12”, the cutting edges 17 of which can protrude more or less over the running surface of the knife basket 19. On the knife basket 19, a stick knife 26 can also be assigned to each knife 12, adjustable _{9 by} means of screws 27 or the like, which can determine the knife cutting opening 28 (see FIG. 2) and thus the chip thickness with the knife 12 ».

After the knife 12 has been set in position with respect to the holding plate 11, this is fixed to the holding plate by means of the screws 13 11 connected. So. the holding plate 11 with knife 12 removed from the setting device and used for insertion in the cutting device =

The base plate 29 is, for example, on a stand 33 arranged and provided in a certain inclined position, so that it is also in an inclined position on the base plate 29 resting knives 12 from those in the lower plate area arranged adjusting screws Uo set up in a favorable manner can be"

The innovation according to the holding device for knives on cutting devices for wood odοdgl ο is simple in construction ,, light in production and cheap. in handling »

Those attached to the knife basket and blunt or worn Knives can be removed from the knife basket in a simple manner remove and replace with new (sharpened) jiaIte devices Replace the existing ^ knife / a subsequent one

_{There is no need to set} up the knives on the knife basket since the knives are already attached to their holding devices. The replacement of the knives can be carried out quickly and easily due to the holding device _{according to the innovation 3,} which means that the Eerspanvor- has considerable downtimes. direction to be avoided.

Furthermore, the device for setting the knife is simple in its position relative to the holding device and easy to use. Because of the cheap fixed The arrangement of the holding devices with the knives on the Kessericorb is always the desired knife setting and thus Chip thickness achieved.

It is part of the innovation .; on a holding device also several "knives to be arranged next to each other." as well as the releasable attachment of the knife to the holding device as well the attachment of the holding device to the knife basket is different; for example by means of tendon tensioning elements or the like.

Furthermore, the fixing devices can also be used differently, like attacks or the like., train »,.
