Description
本發明關於申請專利範圍第1項的引文的一種鋸單元用的縫隙楔裝置(Spaltkeilvorrichtung，英：slit wedge device)。 The present invention relates to a slit wedge device for a saw unit according to the citation of claim 1 of the patent application scope (Spaltkeilvorrichtung, English: slit wedge device).
縫隙楔裝置用於將樑/厚板(Bohle)鋸開成數個層片(薄木片)(Lamelle)。這些工作物一般利用二個鋸單元切鋸，它們具有垂直的鋸心軸，該鋸心軸具有對應數目的鋸片，利用它們將一般預飽過的工作物在水平面中鋸開，沿工作物的運送方向在相關之鋸單元後方設有縫隙楔裝置，其縫隙楔嵌入鋸槽中並防止縫隙變太窄並使得鋸單元卡住而須作再次切割(nachschneiden)的情事。 The slit wedge device is used to saw a beam/blane into several plies (Lamelle). These work items generally use two saw unit saws, which have a vertical saw mandrel with a corresponding number of saw blades, which are used to saw the generally pre-saturated work in the horizontal plane along the work. The direction of transport is provided with a slit wedge device behind the associated saw unit, the slit wedge being embedded in the saw slot and preventing the slit from becoming too narrow and causing the saw unit to jam and having to be re-cut.
此外也可使用在鋸心軸後方倚在層片上的進送滾子，以將工作物運送通過機器，而不會受到由上方來的負荷使鋸片夾入。 Alternatively, a feed roller that rests on the ply behind the saw mandrel can be used to carry the work through the machine without the load being pulled by the load from above.
縫隙楔利用中間框條互相隔開，中間框條大約位於該層片(它們由工作物鋸出來)的高度處。各依層片厚度、鋸片厚度及鋸片路線而定，須使用薄的「配合金屬片」(Passblech)以將縫隙楔帶到鋸縫隙的高度。縫隙楔裝置係固定安裝，且要調整很難且費時，縫隙楔距鋸單元有較大的距離，俾將鋸單元與縫隙楔之間的區域中在鋸切過程產生的碎片(Spreißel)及/或工作物的裂片(Splitter)除去。但往往情形並非可靠地如此進行，因此常常會造成停擺。由於縫隙楔相 對地長，因此它們在鋸縫隙中產生大的摩擦，如此工作物的進送速度受限。 The slit wedges are separated from one another by intermediate strips that are located approximately at the level of the plies (which are sawed by the work). Depending on the thickness of the ply, the thickness of the saw blade and the blade path, a thin "Passblech" is used to bring the gap wedge to the height of the saw gap. The slot wedge device is fixedly installed, and it is difficult and time-consuming to adjust. The slot wedge has a large distance from the saw unit, and the debris generated during the sawing process in the area between the saw unit and the slot wedge (Spreißel) and / Or the split of the work (Splitter) is removed. However, often the situation is not carried out reliably, so it often causes a lockout. Gap phase The ground is long, so they generate large friction in the saw gap, so the feed speed of the work is limited.
此外還有習用的縫隙滾子(Spaltrolle，英：Slit roll)，它們用在工作物的較大進送速度的場合。縫隙滾子可滾入鋸槽中，但縫隙滾子受結構的條件限制，距鋸縫隙的距離還要更大，因此要使用於及配合各加工目的及加工情況更費事。縫隙滾子位於一樞轉臂上，樞轉臂受彈簧施力向工作物的方向頂去，並用彈簧力將縫隙滾子壓入鋸縫隙中，如果縫隙滾子卡在鋸縫隙中或如果鋸縫隙中產生碎片(Spreißel)、工作物裂片或分枝(Äste)或類似物，則縫隙滾子逆著彈簧力從鋸縫隙被壓出來，這種樞轉運動利用一終開關監視，它發出一信號，例如將工作物的進送手段關掉。如此，固然可避免機器損壞，但每次都使機器停止運轉，須由操作者再開動。因此機器的產能減少。 In addition, there are conventional slit rollers (Spaltrolle, Slit roll) which are used in the case of a large feed speed of the work. The gap roller can be rolled into the saw slot, but the slot roller is limited by the structural conditions and the distance from the slot of the saw is larger, so it is more troublesome to use and cooperate with each processing purpose and processing. The slit roller is located on a pivot arm, and the pivot arm is urged toward the workpiece by the spring force, and the slit roller is pressed into the saw slot by the spring force, if the slit roller is stuck in the saw slot or if the saw Fragmentation (Spreißel), workpiece splitting or branching (Äste) or the like, the gap roller is pressed out from the sawing slit against the spring force. This pivoting motion is monitored by a final switch, which emits a The signal, for example, turns off the means of feeding the work. In this way, it is possible to avoid damage to the machine, but the machine is stopped every time and must be restarted by the operator. Therefore, the production capacity of the machine is reduced.
本發明的目的在將上述種類的縫隙楔裝置設計成使它可在所要鋸切的工作物的高速進送速度時可靠地工作。在此，安裝及調整工夫可減到最少。 SUMMARY OF THE INVENTION It is an object of the present invention to design a slit wedge device of the above type such that it can operate reliably at a high speed feed rate of a workpiece to be sawed. Here, the installation and adjustment time can be minimized.
這種目的在上述種類的縫隙楔裝置，依本發明其達成之道係利用申請專利範圍第1項的特徵達成。 This object is achieved in the above-described type of slit wedge device according to the present invention by the features of the first item of the patent application.
在本發明的縫隙楔裝置，該攜帶著「縫隙楔」的「縫隙楔載體」利用驅動器受彈簧彈力以可撓方式在使用位置受力，由於有這種受彈力的可撓性，因此該縫隙楔在故障 時可從鋸縫隙被壓出來，因此可避免縫隙楔裝置及/或機器損壞。此處縫隙楔的長度可以很小，因此它在鋸縫隙中產生的摩擦也相對應地小。如此所要鋸切的工作物可用高進送速度運送。因此鋸單元，或包含此鋸單元的機器可用高功率工作。 In the slit wedge device of the present invention, the "slit wedge carrier" carrying the "slit wedge" is biased in the position of use by the spring by the actuator, and the slit is present due to the elasticity of the elastic force. Wedge in failure It can be pressed out of the saw gap, thus avoiding damage to the gap wedge device and/or the machine. Here, the length of the slit wedge can be small, so that the friction generated in the saw slit is correspondingly small. The work to be sawed in this way can be transported at a high feed speed. Therefore, the saw unit, or the machine containing the saw unit, can operate at high power.
由於使用一實心的縫隙楔載體(縫隙楔與中間框條位置準確地固定在其上)，故縫隙楔和中間框條可很簡單迅速地更換、調整，且在必要時作修正。利用此縫隙楔載體，縫隙楔可調到很接近工具，如此鬆落的分枝甚至不會掉出到縫隙楔前方造成停擺(Stockung)。事實亦顯示，由於調整得很接近，故鬆落的碎片及裂片少得多，這種鬆落的碎片和裂片會造成停擺。 Since a solid slit wedge carrier is used (the slit wedge and the intermediate frame strip are accurately positioned thereon), the slit wedge and the intermediate frame strip can be easily and quickly replaced, adjusted, and corrected if necessary. With this slit wedge carrier, the slit wedge can be adjusted very close to the tool, so that the loose branches do not even fall out to the front of the slit wedge to cause a stocking. The facts also show that because of the close adjustments, there are far fewer loose pieces and lobes, and the loose pieces and lobes can cause a lockout.
本發明的其他特點見於其他之申請專利範圍，以下的說明及圖式。 Other features of the invention are found in the scope of other patent applications, the following description and drawings.

The carrier (8) has an elongated hole (10) extending in the feeding direction (5) of the workpiece (1), and the elongated hole (10) allows the carrier (8) and the entire slit wedge device (6) to be perpendicular to the sawing spindle (2) Or adjust parallel to the feed direction (5). A screw (not shown) extends wide through the slot (10) and is used to secure the carrier (8) to the frame or mandrel mover. A retaining plate (11) is arranged on the carrier (8) to hold a pressing cylinder (12), and a slit wedge carrier (13) can be moved toward the workpiece (1) by the pressing cylinder. Directional force. The retaining plate (11) projects from the carrier plate (14) in the transverse direction (and preferably perpendicularly) of a carrier plate (14). The carrier plate (14) is fixed to the underside of the carrier (8) and projects beyond the edge of the carrier (8) opposite the slit wedge carrier (13). Carrier plate (14) is also available It is situated at the height of the carrier (8) and is designed in one piece with the carrier (8). An angular carrying member (15) is disposed on the carrier plate (14), the vertical leg (16) serving as a holder of a sensor (17), and the sensor (17) is preferably an inductive proximity switch (Näherungsschalter- or -sensor, English: proximity switch). The horizontal leg of the carrying member (15) has at least one (two in this embodiment) long holes (19) through which the screws (20) pass, and the carrier (15) can be fixed to the carrier plate by screws (14). ), and its head rests on the leg (18) [at least one spacer (Beilagscheibe) (21) should be provided in the middle).

如圖1所示，近接開關(17)穿過攜帶件(15)的垂直腿(16)且在其中螺合到一螺紋孔(70)中。它和一保持器(22)配合，保持器(22)的縱中央平面和近接開關(17)的軸平行。由於固定在螺紋孔(70)中，故感測器(17)距保持器(22)的端側(69)的切換距離可準確調整、保持器(22)上固定著一活塞桿(23)，它由壓迫缸(12)突伸出來且穿過保持板(11)，二者之間隙。保持器(22)之背向保持板(11)的那一側固定在一移動器(24)上，在此實施例係利用螺絲(71)(72)(圖1)螺合在其上。但移動器(24)與保持器(22)也可設計成一體，例如互相熔接。移動器(24)嵌入導引元件(9)的一凹陷部(25)且以其二縱側(26)(27)(圖1)倚在凹陷部(25)的側壁(28)(29)上。 As shown in Figure 1, the proximity switch (17) passes through the vertical leg (16) of the carrier (15) and is threaded therein into a threaded hole (70). It cooperates with a retainer (22) whose longitudinal central plane is parallel to the axis of the proximity switch (17). Since it is fixed in the threaded hole (70), the switching distance of the sensor (17) from the end side (69) of the holder (22) can be accurately adjusted, and a piston rod (23) is fixed on the holder (22). It protrudes from the compression cylinder (12) and passes through the retaining plate (11), the gap between the two. The side of the retainer (22) facing away from the retaining plate (11) is secured to a mover (24), which is screwed onto it in this embodiment by means of screws (71) (72) (Fig. 1). However, the mover (24) and the holder (22) can also be designed in one piece, for example, welded to each other. The mover (24) is embedded in a recess (25) of the guiding element (9) and leans against the side wall (28) (29) of the recess (25) with its two longitudinal sides (26) (27) (Fig. 1) on.

Due to the long holes (37) (38), the mover (34) can be adjusted in its longitudinal direction relative to the guiding element (9).
在保持器(22)上，在移動器(24)旁的區域中設有止擋部(41)(42)，利用它們可限制導引元件(9)的移動路徑，止擋部(41)(42)各有一螺絲(43)(44)，穿過保持板(11)，其螺絲頭(46)(48)在保持板(11)前方，而位在各螺絲上的螺母(45)(47)(圖1)在保持板(11)後方。螺絲(43)(44)更穿過保持器(22)並利用螺母(45)(47)及其他和保持器(22)對立的螺母(45’)(47’)(圖2)連接成牢固而可調整的方式。利用壓迫缸(12)可將導引元件(9)經由移動器(24)一直移動到使螺母(45)(47)或螺絲頭(46)(48)(各依移動方向而定)倚靠在保持板(11)上為止，在此位置時，縫隙楔(7)嵌入鋸縫隙中，且中間框條(63)(64)位在工作物左縱側當作導引件。縫隙楔可沿相反方 向一直壓回或移行到該螺母(45)(47)倚在保持板(11)的內側為止。移入位置及移出位置之間的行程可利用上述螺絲(43)(44)固定在保持器(22)上的方式調整，各依縫隙楔嵌入鋸縫隙中多深而定，藉著將上述感測器(17)的切換距離作調整以及將載體板(14)在長孔(19)中移動，可將感測器(17)的切換點調整成使得螺母(45)(47)倚在保持板(11)內側上以及因此限制該行程之前，感測器已離開保持器(22)的檢出範圍。 On the holder (22), a stop (41) (42) is provided in the region beside the mover (24), with which the movement path of the guiding element (9) can be restricted, the stop (41) (42) Each has a screw (43) (44) that passes through the retaining plate (11) with its screw head (46) (48) in front of the retaining plate (11) and a nut (45) on each screw ( 47) (Fig. 1) behind the retaining plate (11). The screw (43) (44) passes through the retainer (22) and is firmly connected by the nut (45) (47) and other nuts (45') (47') (Fig. 2) opposite the retainer (22). And the way it can be adjusted. The pressing element (9) can be used to move the guiding element (9) via the mover (24) until the nut (45) (47) or the screw head (46) (48) (depending on the direction of movement) is resting on Up to the holding plate (11), in this position, the slit wedge (7) is embedded in the saw slit, and the intermediate frame strip (63) (64) is positioned as a guide on the left longitudinal side of the workpiece. The gap wedge can be on the opposite side Pressing or moving back until the nut (45) (47) leans against the inside of the retaining plate (11). The stroke between the moved in position and the removed position can be adjusted by fixing the above-mentioned screws (43) (44) on the retainer (22), depending on how deep the slit wedge is inserted into the slit of the saw, by sensing the above The switching distance of the device (17) is adjusted and the carrier plate (14) is moved in the elongated hole (19), and the switching point of the sensor (17) can be adjusted such that the nut (45) (47) leans against the holding plate (11) The sensor has left the detection range of the holder (22) on the inside and thus the stroke.
導引元件(9)攜帶著縫隙楔載體(13)，縫隙楔載體設計成實心且穩定，且可相對於導引元件(9)調整。縫隙楔載體(13)的下側設有一凸肩(49)(Absatz)，縫隙楔載體(43)以凸肩(49)的一面(50)倚在導引元件(9)上，利用該接到面(50)的凸肩面(51)，縫隙楔載體(13)倚在導引元件(9)的端側(52)上。端側(52)對導引元件(9)的縱側(36)成一鈍角。由於縫隙楔載體(13)相對於導引元件(9)的位置呈傾斜，故縫隙楔裝置(6)可向鋸片(3)接近而不會影響鋸片的操作(圖1)，且不會在移回時與鋸片接觸。此外，如此造成工作物(1)沿進送方向的一方向分量，這點在運動學上是有利的。縫隙楔載體(13)被二個長孔(54)(55)貫穿，長孔宜設置在縫隙楔載體的一半寬度處且二孔前後相隔小小距離，二長孔(54)(55)被螺絲(56)(57)穿過，利用螺絲(56)(57)將縫隙楔載體(13)以可鬆開的方式固定在導引元件(9)上。螺絲頭倚在縫隙楔載體(13)上，其間宜設至少一墊片(58)，因此縫隙楔載體(13)可沿長孔(54)(55)的縱向相對於導引元件(9)調整。 The guiding element (9) carries a slit wedge carrier (13) which is designed to be solid and stable and which is adjustable relative to the guiding element (9). The lower side of the slit wedge carrier (13) is provided with a shoulder (49) (Absatz), and the slit wedge carrier (43) rests on the guiding member (9) with one side (50) of the shoulder (49). To the shoulder surface (51) of the face (50), the slit wedge carrier (13) rests on the end side (52) of the guiding member (9). The end side (52) is at an obtuse angle to the longitudinal side (36) of the guiding element (9). Since the position of the slit wedge carrier (13) relative to the guiding element (9) is inclined, the slit wedge device (6) can approach the saw blade (3) without affecting the operation of the saw blade (Fig. 1), and Will come into contact with the saw blade when moving back. Furthermore, this causes a directional component of the workpiece (1) in the feed direction, which is kinematically advantageous. The slit wedge carrier (13) is penetrated by two long holes (54) (55), and the long holes are preferably arranged at half the width of the slit wedge carrier and the two holes are separated by a small distance, and the two long holes (54) (55) are The screw (56) (57) is passed through, and the slit wedge carrier (13) is releasably fastened to the guiding member (9) by means of screws (56) (57). The screw head rests on the slit wedge carrier (13) with at least one spacer (58) therebetween, so that the slit wedge carrier (13) can be oriented relative to the guiding member (9) along the longitudinal direction of the elongated hole (54) (55) Adjustment.
縫隙楔載體(13)的前側上設有一凹陷部(59)，它朝向縫隙楔載體(13)的端側(60)及縱側(61)開口，在凹陷部(59)中，縫隙楔(7)保持在二中間框條(63)(64)之間，其中下面的框條(63)倚在凹陷部(59)的底(62)上。中間框條(63)(64)以及其間的縫隙楔(7)被二螺絲(65)穿過，利用螺絲將它們固定在凹陷部(59)的底(62)上。中間框條(63)(64)也突伸超出縫隙楔載體(13)的端側(60)及縱側(61)之外。為了使縫隙楔(7)能嵌入工作物(1)的鋸槽中，故縫隙楔突伸超過縫隙楔載體(13)的縱邊(61)的長度比中間框條(63)(64)更多。圖2中只顯示一縫隙楔(7)。但縫隙楔載體(13)有多數縫隙楔(7)，其數目和所要鋸切的層片相當，這些縫隙楔(7)利用稜條互相隔開。 The front side of the slit wedge carrier (13) is provided with a recess (59) which opens toward the end side (60) and the longitudinal side (61) of the slit wedge carrier (13). In the recess (59), the slit wedge ( 7) Between the two intermediate frame strips (63) (64), wherein the lower frame strip (63) rests on the bottom (62) of the recess (59). The intermediate frame strips (63) (64) and the slit wedges (7) therebetween are passed through by two screws (65), which are fixed to the bottom (62) of the recessed portion (59) by screws. The intermediate frame strip (63) (64) also projects beyond the end side (60) and the longitudinal side (61) of the slit wedge carrier (13). In order to enable the slit wedge (7) to be inserted into the saw groove of the workpiece (1), the slit wedge protrudes beyond the longitudinal edge (61) of the slit wedge carrier (13) more than the intermediate frame strip (63) (64). many. Only one slit wedge (7) is shown in FIG. However, the slit wedge carrier (13) has a plurality of slit wedges (7) equal in number to the layers to be sawed, and the slit wedges (7) are separated from one another by ribs.
縫隙楔載體(13)的端側(60)對其縱側(61)成一銳角，相反側的端側(66)對縫隙楔載體(13)的縱側(61)成直角(圖1)。如此，縫隙楔載體(13)可移到很靠近左邊的鋸子的鋸片(3)。縫隙楔(7)可用下文將說明的方式調整，使它只距離工具的軌跡圓(Flugkreis，英：flight circle)一段很小的距離，例如只有約3毫米。由於縫隙楔(7)與工具的軌跡圓之間距離很小，故在鋸切時很少故障。在木材中的分枝(Äste)由於縫隙楔(7)和鋸子之間距離很小，甚至不會掉出來，且碎片和裂片也很少會從工作物(1)鬆落。 The end side (60) of the slit wedge carrier (13) forms an acute angle to its longitudinal side (61), and the opposite side end side (66) is at right angles to the longitudinal side (61) of the slit wedge carrier (13) (Fig. 1). Thus, the slit wedge carrier (13) can be moved to the saw blade (3) of the saw very close to the left. The slit wedge (7) can be adjusted in such a way that it is only a small distance from the tool's trajectory circle (Flugkreis, flight circle), for example only about 3 mm. Since the distance between the slit wedge (7) and the trajectory circle of the tool is small, there is little trouble in sawing. The branch in the wood (Äste) does not even fall out due to the small distance between the slit wedge (7) and the saw, and the fragments and lobes are rarely loosened from the work (1).
在圖1中的建入位置，長孔(54)(55)平行於進送方向(5)延伸。如此，縫隙楔載體(13)可朝向工具調整，使縫隙楔(7)距工具只有上述之小小距離。 In the built-in position in Fig. 1, the long holes (54) (55) extend parallel to the feed direction (5). In this way, the slit wedge carrier (13) can be adjusted towards the tool such that the slit wedge (7) is only a small distance from the tool.
縫隙楔(7)只延伸過該縫隙楔載體(13)的長度[沿進送方 向(5)測量的長度]的一部分。由於其長度短，故該縫隙楔(7)可很容易操作及廉價製造，為了要使縫隙楔(7)和中間框條(63)(64)能簡單而準確地定位在縫隙楔載體(13)的凹陷部(50)中，故該凹陷部(59)的平坦底(67)[它接到縱側(61)]當作倚靠面以供縫隙楔(7)和中間框條(63)(64)倚靠。此外，它們可倚靠在該凹陷部(59)之接到底(67)的側壁(68)上。由於這種設計，縫隙楔(7)和中間框條(63)(64)在縫隙楔裝置(6)調整到新的加工目的時可迅速更換，也可迅速簡單地作修正以及將「配合金屬片」放入。由於縫隙楔(7)很短，故它們和工作物(1)之間的摩擦大大減少，因此可用很高的進送速度移行。 The slit wedge (7) extends only over the length of the slit wedge carrier (13) [along the feed side A part of the length measured to (5). Due to its short length, the slit wedge (7) can be easily handled and inexpensively manufactured in order to enable the slit wedge (7) and the intermediate frame strip (63) (64) to be simply and accurately positioned in the slit wedge carrier (13). In the recessed portion (50), the flat bottom (67) of the recessed portion (59) is attached to the longitudinal side (61) as a resting surface for the slit wedge (7) and the intermediate frame strip (63) (64) Trust. In addition, they can rest on the side wall (68) of the recess (59) which is connected to the bottom (67). Due to this design, the slit wedge (7) and the intermediate frame strip (63) (64) can be quickly replaced when the slit wedge device (6) is adjusted to a new processing purpose, and can be quickly and easily corrected and the "mating metal" The piece is placed. Since the slit wedges (7) are short, the friction between them and the workpiece (1) is greatly reduced, so that it is possible to move at a high feed speed.
在圖示的實施例，該縫隙楔(7)之嵌入工作物(1)中長度比縫隙楔載體(13)的一半長度的一半小，且宜只約為其長度的三分之一。 In the illustrated embodiment, the length of the embedded workpiece (1) of the slit wedge (7) is less than half the length of the slit wedge carrier (13) and preferably only about one third of its length.
載體(8)可平行於進送方向(5)在機架上或心軸移動器上相對於使用的工具準確調整。移動器(24)可沿其縱方向利用螺絲(39)和長孔(37)相對於導引元件(9)作無段式調整。由於縫隙楔載體(13)也可相對於導引元件(9)調整。故縫隙楔(7)可最佳地配合所用的工具的軌跡圓直徑以及所要加工的工作物(1)的寬度，而不會影響近接開關(17)的切換的。在第一次基本調整後，具有保持器(22)的移動器(24)相對於感測器(17)經常保持在相同位置。 The carrier (8) can be accurately adjusted parallel to the feed direction (5) on the frame or on the mandrel mover relative to the tool used. The mover (24) can be steplessly adjusted in its longitudinal direction with respect to the guiding element (9) using screws (39) and elongated holes (37). Since the slit wedge carrier (13) can also be adjusted relative to the guiding element (9). Therefore, the slit wedge (7) can optimally match the diameter of the track circle of the tool used and the width of the workpiece (1) to be processed without affecting the switching of the proximity switch (17). After the first basic adjustment, the mover (24) with the retainer (22) is often held in the same position relative to the sensor (17).
整個縫隙楔裝置(6)利用壓迫缸(12)壓入鋸縫隙中，換言之，縫隙楔(7)可靠地壓入工作物(1)的鋸縫隙中。中間框條 (63)(64)用於限制縫隙楔(7)進入鋸縫隙中的侵入深度。此外，中間框條(63)(64)在工作物(1)運送通過工具時將工作物導引，其中工作物(1)倚在其縱側上作導引。 The entire slit wedge device (6) is pressed into the saw gap by means of a compression cylinder (12), in other words, the slit wedge (7) is reliably pressed into the saw gap of the workpiece (1). Middle frame (63) (64) is used to limit the depth of penetration of the slit wedge (7) into the saw gap. In addition, the intermediate frame strip (63) (64) guides the work when the work item (1) is transported through the tool, wherein the work object (1) is guided against its longitudinal side.
縫隙楔載體(13)本身可用簡單方式定位在導引元件(9)上，因為凸肩(49)的面(51)倚靠在導引元件(9)的端側(52)上。 The slit wedge carrier (13) itself can be positioned on the guiding element (9) in a simple manner, since the face (51) of the shoulder (49) rests on the end side (52) of the guiding element (9).
壓迫缸(12)產生一種可撓性的壓迫壓力到縫隙楔(7)上，如果發生故障(因為在鋸縫隙中有碎片、裂片或鬆落的分枝跑到縫隙楔(7)上)，則整個縫隙楔裝置(6)移回一段距離，使縫隙楔(7)從鋸縫隙脫離出來。 The compression cylinder (12) produces a flexible compression pressure onto the slit wedge (7) if a failure occurs (because there are fragments, lobes or loose branches running into the slit wedge (7) in the saw gap), Then the entire slit wedge device (6) is moved back a distance to disengage the slit wedge (7) from the saw slit.
縫隙楔裝置(6)調整成使近接開關和保持器(22)之相鄰的端側(69)對立(圖1及圖2)。如果縫隙楔裝置(6)由於故障而被壓回在鋸縫隙中，則保持器(22)跑到感出器(17)的檢出範圍。它發出一切換脈波，送到一控制手段。利用此控制手段，舉例而言，利用控制手段可將工作物(1)的進送手段停下來或將鋸心軸關掉。用此方式可避免縫隙楔裝置(6)，鋸心軸(2)、工具(3)或其他工具部分損壞。此外可利用切換脈波將縫隙楔(7)藉著將壓迫缸(12)切換而完全調整(一直到進入終位置為止)，如此，縫隙楔裝置(6)由於故障而損壞之虞更小了。 The slit wedge means (6) are adjusted such that the adjacent end faces (69) of the proximity switch and the retainer (22) oppose each other (Figs. 1 and 2). If the slit wedge device (6) is pressed back into the saw gap due to a fault, the retainer (22) runs to the detection range of the sensor (17). It sends a switching pulse and sends it to a control. By means of this control means, for example, the means of feeding the workpiece (1) can be stopped or the saw spindle can be closed by means of control means. In this way, it is possible to avoid damage to the slit wedge device (6), the saw mandrel (2), the tool (3) or other tools. In addition, the slit pulse (7) can be completely adjusted by switching the pressing cylinder (12) by switching the pulse wave (up to the end position), so that the slit wedge device (6) is less damaged due to the failure. .
在感測器(17)的另一種設置方式，它也可設成使得在縫隙楔裝置(6)的基本位置[亦即在缸(12)移出之時]保持器(22)在感測器(17)的檢出範圍外且不會將感測器切換。當縫隙楔壓回時，保持器(22)就進到感測器(17)的檢出範圍中，如此，切換脈波就發出。 In another arrangement of the sensor (17), it can also be arranged such that the holder (22) is in the sensor at the basic position of the slot wedge device (i.e., when the cylinder (12) is removed) The detection range outside (17) does not switch the sensor. When the slit wedge is pressed back, the retainer (22) enters the detection range of the sensor (17), and thus, the switching pulse wave is emitted.
由於上述之實施方式及調整，保持器(22)可不受工作物寬度及/或鋸子的軌跡圓直徑的影響，準確地調整到近接開關(17)。因此切換點不受工作物寬度或軌跡圓直徑影響始終一樣，如此，縫隙楔裝置(6)可迅速簡單地調整成不同之工作物寬度和軌跡圓直徑。 Due to the above-described embodiments and adjustments, the retainer (22) can be accurately adjusted to the proximity switch (17) regardless of the width of the workpiece and/or the diameter of the track circle of the saw. Therefore, the switching point is always the same regardless of the width of the workpiece or the diameter of the track circle. Thus, the slit wedge device (6) can be quickly and easily adjusted to different workpiece widths and track circle diameters.
上述之縫隙楔裝置(6)[它和左邊的鋸子配合]產生上述之彈性可撓性的壓迫力量。也有一縫隙楔裝置和右邊的鋸子配合，但它並不利用彈簧力設成垂直於工作物(1)之運送方向(5)，而係相對於止擋部固定設置，此縫隙楔裝置(6)可同樣平行於進送方向(5)朝向右邊鋸子調移，俾能配合不同大小的軌跡圓直徑。 The slit wedge device (6) described above [which cooperates with the saw on the left side] produces the aforementioned elastically flexible compressive force. There is also a slit wedge device that cooperates with the saw on the right side, but it is not set to be perpendicular to the transport direction (5) of the workpiece (1) by the spring force, but is fixedly disposed relative to the stop portion, and the slit wedge device (6) ) It can also be moved parallel to the feeding direction (5) towards the right saw, which can match the diameter of the trajectory circle of different sizes.
此縫隙楔裝置可用於達約70米/分的進送速度、約250毫米~約400毫米的鋸的軌跡圓直徑以及約50毫米~約150毫米的工作物寬度。在此，縫隙楔(7)可調到很接近工具軌跡圓。此段距軌跡圓直徑的距離很有利地只有約3毫米。 The slit wedge device can be used for a feed speed of about 70 m/min, a track circle diameter of a saw of about 250 mm to about 400 mm, and a work width of about 50 mm to about 150 mm. Here, the slit wedge (7) is adjustable to be very close to the tool path circle. The distance of this segment from the diameter of the trajectory circle is advantageously only about 3 mm.
