Description of the Invention: [Technical Field] The present invention relates to a sheet feeding device; and more particularly to a conveying method in which the first conveying device is not subjected to a pulling force in the conveying direction to convey the sheet edge The direction is shifted in the up and down direction to move to the second transport device. [Prior Art] A conventional method generally employs a conveying device that conveys a plurality of sheets in an approaching state and places them in a stacking manner. Usually, such a stacking operation needs to occur in a state in which one sheet of material is being stacked, and the next stacking means, the sheet of the veneer and the members of the stacking device are stacked. Therefore, in the above state, the time interval of the φ sheet material is set to be a predetermined time based on the time when one sheet of sheet material reaches the stacking sheet, and the conveying path is changed for the sheet material conveyed in the above state. In the case of each conveying path, the time for conveying the length of one sheet is set as the basis. a conventional prior art device, such as a lower front conveyor (conveyer) 1 〇〇 along the lower conveyor belt 101, which has a lower front conveying method and its conveying plate, almost the first The second conveying device of the conveying device is placed in the conveying direction, for example, for a certain period of time, for example, the sheet has already reached the pile, so that the plurality of conveying devices cannot be relaxed until the bottom is lowered. A plurality of sheets are stacked with a diameter stacking device for a certain period of time or more. As shown in the figure 28, on the downstream side of the direction, the conveying speed of the conveyor is *^ 201026585 degrees vlO faster than the pre-set speed conveying speed vll. In the lower front machine 100, a plurality of sheets 102 are transported from the lower front conveyor 100 to the rear conveyor 1 较1 in a state in which the spacing between the adjacent sheets 102 is relatively different, so that the sheets 102 are shifted. [Explanation of the above-mentioned contents] [Problems to be solved by the invention] However, in such a device, when the sheet material 102 is transferred from the lower front conveyor to the lower rear conveyor 101, the front portion of the sheet 102 is opposite At the contact between the conveyor 100 and the lower rear conveyor 101, a tensile force occurs. Therefore, if the fiber direction of the veneer is a vertical direction and the plate having a small degree of pull is broken, cracking may occur, and the problem of being unusable may be caused. In the above-described conventional device, the lower rear conveyor 101 is above the downstream side of the conveyance. It is repeated only in the conveying area of the appropriate length, and the opening of the upper portion 103 is relatively wider than the thickness of the sheet 102, and the conveying speed V12 is faster than the conveying v 1 1 of the lower rear conveyor 101. The lower rear conveyor 101 and the upper conveyor 103 are overlapped, and a jet device 104 that ejects air upward is provided. In Fig. 28, the plate conveyed by the upper conveyor 103 collides with the baffle 105, so that the plate 102 is stopped at a certain position, and the table 106 is used for stacking the plate 102 which collides with the baffle 105 and falls thereon. In the apparatus, the lower portion of the board transport conveyed by the lower rear conveyor 101 is large. 1 00 is in contact with the lower extension 〇 direction and the conveyor speed region 102 is stacked 〇 102 -5- 201026585 Entering the repeating region, the sheet 102 is pressed against the upper conveyor 103 by the air from the jet device 104. Then, the plate member 102 receives the frictional force from the upper conveyor 103, and the speed vl2 of the upper conveyor 103 is conveyed to the left. If the sheet material 102 is conveyed above the jet apparatus 1〇4, the air of the gas-spraying unit 104 does not act on the sheet material 1〇2. Therefore, the plate member 102 is moved to the left side, and collides with the baffle plate 105 while falling, and is prevented from falling to the left side and is deposited on the stacking table 106. However, if the sheet material 102 conveyed by the lower rear conveyor 101 receives air from the air jet device 104, as shown in the sheet material 102a, initially, the vicinity of the downstream side end portion is lifted to the upper conveyor 103 along the conveying direction of the sheet material 102a. The side is crimped to the side of the upper conveyor 1〇3. Therefore, the portion of the plate member 102a which is crimped to the upper conveyor 103 side is conveyed at the speed v12, and the portion of the plate 102a which is located at the lower rear conveyor 1〇1 is conveyed at the speed lv1. As a result, the tensile force acts on the plate member 102a, which is the same as the conventional technique, and when the tensile strength of the material is small, cracking may occur and the use may be impossible. Further, in the inclined portion where the plate member 102a is in contact with the lower rear conveyor 101 or the upper conveyor 103, the weight of the inclined portion acts on the portion in contact with the upper conveyor 103; thus, the above-mentioned problem is also caused. [Means for Solving the Problem] -6- 201026585 The method for conveying a sheet of the present invention and the conveying device thereof, when the sheet conveyed by one conveying device is moved to another conveying device, the entire sheet can be moved together, The sheet will be pulled, so there will be no cracking of the sheet.

It is narrowed so that the connecting pipe 4d is connected to the above-described vacuum device 4f. In the lower portion of the connecting pipe 4d, a plurality of suction devices 4Z are provided at equal intervals along the conveying direction. In the present embodiment, three suction devices 4z are provided in the s region, and three suction devices 4z are provided in the T region.

The positional relationship between the above-mentioned connecting pipe 4d, the connecting portion 4w, the suction hopper 4a, and other members -11 - 201026585 is as shown in Fig. 3. On the lower end side of each of the suction buckets 4a, a plurality of suction ports 4h of a suitable shape suitable for sucking air are formed in a dispersed manner, and projections 4g are provided in the vertical direction on the left and right sides. In the connecting portion 4w, a disk-shaped opening and closing valve 4b is provided, and the support shaft 4j is provided in the connecting portion 4w, and as shown by the arrow in Fig. 3, the suction operation of the suction port 4h is caused by the reciprocating rotation of the air cylinder 4c. Start or stop. Along the conveying direction, between the two pulleys 3b, the conveyor belt 3c is positioned thereon, as shown in Fig. 3, and moves substantially along the side of the projection 4g, as described above, by the suction buckets 4a. The plate, the vacuum device 4f has a degree that the inside of the connecting pipe 4d can be depressurized to the extent necessary for attracting the veneer. Further, the lengths of the three suction devices 4z are arranged to be equal to the length of each of the veneers described later along the transport direction. The forced dropping member 5 is provided in the T region of the first upper conveyor 3. The forced dropping member 5 is composed of two plate-shaped pressure plates 5a (relative to one suction device 4z) and a cylinder 5b for lifting and lowering the pressure plate 5a in parallel with the sheet conveying direction. By the action of the air cylinder 5b, the two strip-shaped pressure plates 5a are lowered from the position shown in Fig. 1 to the position indicated by the broken line, and then rise back to the position shown by the solid line in Fig. 1 so as to be stacked. The plate is pressed from the position shown in Fig. 1 to the position of the uppermost veneer stacked on the veneer 11 to which the veneer group has been stacked. The operation of the air cylinder 5b is performed as described later, when the veneers 2f, 2g, 2h, etc. are transported to the upper side of the stacking table 10, and the veneers 2f, 2g, 2h, ... are pushed downward, It is deposited on the plate 1 1 placed on the stacking table 10 in a short time. The first single-plate detector 6 is formed in the S region of the first lower conveyor 1 and is formed by a reflective photocell disposed at the downstream end of the veneer conveying direction for detecting whether or not a single veneer is transported to the entire area. The S area is sent to the control unit 8 for the board detection signal. The second single-plate detector 7 is formed in the T region of the first upper conveyor 3 by a reflective photocell provided at the downstream end of the veneer conveying direction, and is used to detect whether or not a single veneer is transported as a whole. Up to the top of the stacking table 10, a single board detection signal is sent to the control unit 8. The roller 50 that can be freely rotatable is provided. As shown in FIG. 3, the holding portion 51b is provided at the tip end of the piston rod 51a of the cylinder 51 fixed to a base (not shown), and the roller 50 is disposed at the holding portion via a bearing. On 51b. The roller 50 is moved back and forth between the ascending position and the # descending position by the action 'of the cylinder 51 as described above, and the aforementioned rising position is indicated by a solid line in FIG. 3 when the veneer and the first upper conveyor 3 are When the conveyor belt 3c is crimped, it is not in contact with the veneer; the aforementioned lowered position is indicated by a solid line in Fig. 1 and is in contact with the upper surface of the veneer conveyed by the first lower conveyor 1. The control mechanism 8 has a delay circuit 'the control mechanism 8 receives the above-described detection signal to control the operation of each member. The first lower conveyor 1 is driven by the motor 1e' to the first upper conveyor 3 by the motor 3e in the direction of the arrow shown in the figure - 13 - 201026585. The stacking table 10 is used for stacking and transporting by the conveying device of the present invention. Each of the veneers ' is disposed below the T region of the first upper conveyor 3 described above. The plate 11 is placed on the output machine 10a provided on the stacking table 10 for placing the veneers. The stacking table 10 is configured to perform a lifting operation in the direction of the arrow in the first drawing by a generally known control mechanism (not shown). When the boards are sequentially stacked on the board 1 1 , the stacking board is composed of a plurality of stacked sheets. The topmost veneer of the stacked veneer set 2A 成为 becomes a certain height. As described above, the conveying apparatus according to the first embodiment of the present invention will sequentially describe the series of operations from the state of each member and each of the boards shown by the solid line in Fig. 1 . In the state of the first embodiment, the opening and closing valve 4b of the three suction devices 4z existing in the T region is open to the vertical direction, and the suction veneer 2f is pressed against the conveyor belt 3c by the frictional force of the conveyor belt 3c. , transported in a direction perpendicular to the direction of the fiber (ie, the direction of the arrow). ❹ On the other hand, the opening and closing valve 4b of the suction device 4z in the S region is turned in the horizontal direction, and does not attract the veneer. In the first lower conveyor 1, the veneers 2g, 2h... are transported in a direction perpendicular to the direction of the sheet fibers, and the transport direction is of equal length, and the adjacent veneers are transported along the transport direction with almost no space between them. . In the above state, the veneer 2f is further transported, and reaches the stacking table 10 in the transport direction thereof until reaching the second veneer detector 7. Then, the second board detector 7 sends a detection signal to the control unit 8, and the control unit 8 that receives the signal sends an action signal to cause the respective components-14-201026585 to perform corresponding actions, and the actions of the components are as follows: The corresponding cylinder 4c is operated so that the opening and closing valve 4b of all the suction devices 4Z in the τ region is rotated to the closed state to stop the suction action, and the cylinder 5b of the forcible dropping member 5 is operated. As a result, as shown in Fig. 4, the veneer 2f is dropped by its own weight and the thrust received from the platen 5a downward, and is deposited on the veneer group 2A which has been deposited on the veneer 11. 〇 After the pressure plate 5a is lowered, the pressure plate 5a is quickly raised back to the original position by the action of the cylinder 5b (as shown by the solid line in Fig. 1). On the other hand, while the single board 2f is dropped onto the board group 2A as described above, the subsequent board 2g is also controlled to operate as follows: The board 2g is in the state of the first figure, and the first lower part is The conveyor 1 is transported in the conveying direction thereof at the conveying speed v1 to the s-zone until the first veneer detector 6. Then, the first board detector 6 sends a detection signal β to the control unit 8, and the control unit 8 that receives the signal emits a signal for causing each member to perform an action, so that each member performs a corresponding action, and the actions of the members are as follows. : the corresponding cylinder 4c is operated so that the opening and closing valve 4b of all the suction devices 4z in the weir region is brought into an open state to generate an attracting action, and the cylinder 51 is caused to perform an ascending motion, so that the roller 50 in the lowered position rises. . Therefore, the veneer 2g is attracted to the first upper conveyor 3 and is pressed against the conveyor belt 3c. Originally, the speed of the forward direction of the veneer 2g is vl, and the conveying speed of the conveyor belt 3c -15-201026585 is v2, so that the veneer 2g is accelerated from the conveying belt 3c by the frictional force in the conveying direction (for example, the fourth As shown in the figure, the veneer 2g is transported in the direction of the arrow at the conveying speed v2 of the first upper conveyor 3. At the time of acceleration, the entire plate 2g generates a frictional force in the conveying direction, so that the veneer 2g is conveyed without pulling force, so that cracking does not occur. Next, the veneer 2g is moved toward the τ zone by the transport of the first upper conveyor 3. After the control unit 8 receives the signal from the first board detector 6, the control unit 8 passes the preset time through the built-in delay circuit, and sends an action signal for causing each cylinder 4c to operate in sequence, with the single The position at which the board 2g moves corresponds. In this manner, before the veneers 2g are moved in the transport direction to the respective suction devices 4z that are about to reach the T region, the opening and closing valves 4b of the suction devices 4z are rotated to an open state, and the three suction devices in the T region are rotated. In 4z, it proceeds sequentially from the upstream side to the downstream side in the transport direction. As a result of the above, as shown in the order of Fig. 5, Fig. 6, and Fig. 7, the veneer 2g is continuously attracted to the first upper conveyor 3, and is transported to the upper side of the stacking table 1 by pressure bonding. In the same manner as the single board 2f, the single board 2g is dropped and stacked on the single board group 2A. In the S area, the control unit 8 that receives the signal from the first board detector 6 sends out an action signal that sequentially performs the following actions through the delay circuit, that is, the upstream end of the first board 2 g in the transport direction passes through the roller 5 The armpit 16 - 201026585 ends, and the downstream side end portion of the next single plate 2h conveyed by the first lower conveyor 1 reaches the lower side of the roller 50, at which time the cylinder 51 is actuated, so that the roller 5 0 moves to the lowered position, and as shown in Fig. 5, the roller 50 is in contact with the upper surface of the veneer 2h. When the roller 50 is moved to the lowered position, the suction device 4z on the most upstream side in the transport direction of the S region is still in a suction state, and the veneer 2h is originally attracted to rise, but the roller 50 is in contact with the veneer 2h, and therefore, Prevent the φ board from being attracted to rise 2h. Further, when the single plate 2g passes through the suction device 4z of the S region in the transport direction by the operation signal sequentially sent from the control unit 8 via the delay circuit, the opening and closing valve 4b is rotated to the closed state. As described above, in the S region and the T region of the first upper conveyor 3, only the suction device 4z passing through the veneer portion is caused to attract, as will be further described below: the suction device 42 that does not pass through the veneer portion When the action generates suction for β, a large amount of air is taken in from the suction port 4h of the suction bucket 4a of the portion. The pressure in the connecting pipe 4d in the decompressed state is brought close to the atmospheric pressure, and the suction force of the first suction member group 4 passing through the single plate portion is weakened, so that the veneer is dropped. Then, the veneer 2h transported by the first lower conveyor 1 is detected by the first veneer detector 6 in the transport direction, and performs the same operation mode as the above-described veneer 2g, and is sucked up to the first upper transport together. The machine 3, like the above-described veneer 2g, is accelerated and transported at the conveying speed v2 of the first upper conveyor 3. The operation time of v 1 , v2 and the forced dropping member 5 is set, and from the time when the single 17-201026585 plate 2g starts to be conveyed at the conveying speed v2 of the first upper conveyor 3, the next upper plate 2h is conveyed to the first upper portion. In the period Q during which the conveyance speed v2 of the machine 3 starts to be conveyed, the falling operation of the veneer by the forcible dropping member 5 is completed, and the veneer can be stacked without any trouble. The enthalpy of the difference between the time Q and the two transport speeds (v2-vl) is the distance 値 between the veneer 2g transported by the first upper conveyor 3 and the veneer 2h in the transport direction.藉 By repeating the same operation, it is possible to sequentially deposit a plurality of veneers which are transported in a state where there is almost no space between adjacent veneers in the transport direction by the first lower conveyor 1. As described above, the first plate of the first lower conveyor 1 for the transport direction is bundled one by one, and is sucked up toward the first upper conveyor 3 side to be pressed. That is, the frictional force from the conveyor belt 3c acts as a whole on one veneer conveyed in the conveying direction at the speed vl. Therefore, in the conveying direction of the veneer, there is no tensile force, and in the state where the single plate is not broken, the interval between the veneers can be increased in the conveying direction. Next, a second embodiment of the conveying device of the present invention will be described. The purpose of the second embodiment is the same as that of the first embodiment. Fig. 8 is a partially cutaway side explanatory view of the veneer conveying device, and Fig. 9 is a rear explanatory view of the conveying device shown in Fig. 8 as seen from the right side. The second embodiment is different from the first embodiment in the configuration of the second upper conveyor 9 and the forced dropping member 5 of the first embodiment is not used. The second upper conveyor 9 is composed of conveyor belts 9c and 9h, and the conveyor belt 9c is located in the S region. The conveyor belt 9h is located in the T region, and is independent of the movement of the bulls 18-201026585. The first-upper conveyor 3, which is constituted by a conveyor belt 3c instead of the S-zone to the T-zone in the first embodiment, will be described in detail below. Reference numeral 9 denotes a second upper conveyor which is a conveyor 9A on the upstream side in the veneer transport direction (hereinafter simply referred to as "upstream conveyor 9A") and a conveyor 9B on the downstream side in the veneer transport direction (hereinafter abbreviated as " The downstream side weir conveyor 9B") is constructed. The upstream conveyor 9A is provided with a rotary shaft 9a, a pulley 9b, a conveyor belt 9c, a suitable motor 9e, and the like. The upstream side conveyor 9A is disposed above the downstream side in the conveying direction of the first lower conveyor 1 in the first embodiment, and the upstream side conveyor 9A and the downstream side conveyor 9B have the length of the veneer in the conveying direction. A relatively repeated transport area (hereinafter, the same as the first embodiment, the overlap area is referred to as an "S area"), and the interval with the first lower conveyor 1 is configured to be larger than the thickness of the above-mentioned veneer interval. The upstream side conveyor 9A moves at any time in the direction of the arrow in the direction of the conveyance speed v2 which is faster than the conveyance speed v1 of the first lower conveyor 1. The downstream conveyor 9B is composed of a rotating shaft 9f, a pulley 9g, a conveyor belt 9h, and a motor 9j that can be driven/stopped, and a transporting region for transporting the veneer is formed above the stacking table 10 (hereinafter, with the first embodiment) Again, this area is referred to as the "T area"). According to the operation signal from the control unit 8A, the downstream side conveyor 9B can be controlled to move or stop at a transport speed equal to v2. -19-201026585 In the downstream side of the rotating shaft 9a on the downstream side in the transport direction of the two rotating shafts 9a of the upstream side conveyor 9A, 9g is required to be rotatably attached to the rotating shaft 9a, as described above, except for forcibly falling. The member lead member group 4 and the like are the same as the first embodiment. Further, the same roller 50 that is freely movable up and down is provided. Further, a control unit 8A is provided to receive the detection signals from the detector 6 and the second board detector 7. The second embodiment is configured as described above, and the state of each member and each of the veneers will be described below. In this state, the opening and closing valve 4b of the veneer transporting device 4z in the T region is opened, and the plate 2s is placed. It is transported by the conveyor belt 9h. On the other hand, the opening and closing valve 4b of the device 4z is in a closed state. In the ninth aspect, as shown in the state of Fig. 8, the state and shape of the first embodiment are transported, and the veneer 2s is transported in the direction perpendicular to the direction of the second upper fiber transport, and transported to and along the transport direction until The board 2s downstream side detector 7 detects. Then, from the second board detector 7 to the control unit signal, the signal sent from the control unit 8A of the signal is received, and the operation of each member is explained as follows: that is, the motor 9j is initially stopped and stopped.

在第二實施例中，可以不使用強制落下構件5，但是 ，若使用強制落下構件5,單板比自然落下速度更快，能 縮短堆積所需要時間。以增加效率。 Φ 以下，說明本發明的輸送裝置的第三實施例。 第三實施例與第一實施例以相同狀態藉由輸送裝置以 將沿運送方向單板與相鄰單板之間隔予以擴展的間隔來運 送。 第14圖是第三實施例的單板輸送裝置的局部剖切側 面說明圖，第一下部輸送機1與第一實施例構造相同，輸

的三個吸引裝置4z的開閉閥4b爲關閉狀態，單板2χ 一 -24- 201026585 邊被沿該方向最下游側的開閉閥4b成爲開放狀態的一個 吸引裝置4z吸引，一邊由輸送帶12c輸送，被移到輸送 帶13c上。 在第一下部輸送機1中，運送與第一實施例相同狀態 及形狀的多張單板。 從第14圖的狀態，藉由第一下部輸送機1，進一步 運送單板2y、2z·..，單板2y的沿輸送方向的下游側端部 Φ 被第一單板檢測器6檢測到。 於是，從第一單板檢測器6向控制機構8B發送檢測 訊號，接收到該訊號的控制機構8B發出使得各構件按如 下述動作的訊號。 也就是立即使得氣缸4c動作，以便使得上述三個第 二吸引構件組4A的吸引裝置4z的開閉閥4b —起旋轉到 開放狀態。 其結果，第一下部輸送機1上的單板2y與第一實施 ® 例相同’如第1 5圖所示，一起被吸引上升到第三上部輸 送機12側，與輸送帶12c壓接。 在單板2x的大部分換移到輸送帶13c上時，從控制 機構8B發出使位於單板運送方向最下游側的吸引裝置4z 的開閉閥4b成爲關閉狀態的動作訊號，以中止吸引。 如上所述，與輸送帶12c壓接的單板2y與第一及第 二實施例相同，速度從vl變化到v2，在第三上部輸送機 1 2被輸送。 在單板2y的沿運送方向的下游側端部到達上述位於 -25- 201026585 最下游側的吸引裝置4Z前，從控制機構8B發出使得氣缸 4c動作的訊號，使得其開閉閥4b旋轉到開放狀態，以使 其吸引單板。 於是，單板2y如第16圖所示，一邊與輸送帶12c壓 接，一邊繼續被輸送，不久，單板2y換移到輸送帶13c 上。 另一方面，與該單板2y移動相對應，根據控制機構 Φ 8B的經延遲電路經過預先設定的時間後依序發出的動作 訊號，與第一實施例相同，使得各吸引裝置4z的開閉閥 4b從沿運送方向上游側到下游側的順序，使其旋轉到關 閉狀態，以使得單板已通過處的吸引裝置4z不進行吸引 〇 如上所述，第三實施例也與第一實施例相同，即使第 一下部輸送機1上的單板由第三上部輸送機12運送，在 單板的運送方向不會產生拉伸力。 β 因此’能在沿運送方向增大單板相互之間的間隔狀態 下輸送。 以下，說明本發明的輸送裝置的第四實施例。 第四實施例的目的在於，變更運送通道，使得在第一 輸送裝置以第一至第三實施例相同的狀態運送多張單板之 中選擇的單板，例如每隔一張的單板，在與其他單板不同 的運送通道運送。 第17圖是第四實施例的單板輸送裝置的局部剖切側 面說明圖’第一下部輸送機1與第一實施例構造相同，輸 -26- 201026585 送帶lc隨時以輸送速度vl移動’還設有第一單板檢測器 6 〇 使得傾斜輸送機14與該第一下部輸送機1連接’所

施例組成相同的吸引裝置4z。 如第17圖所示，在第三吸引構件組4B的沿單板運送 方向的上游側及下游側分別配置旋轉軸12a、帶輪12b， 架設輸送帶12c，藉由馬達（沒有圖示），使該輸送帶 ® 12c以速度vl移動，來組成第四上部輸送機17» 另外，設有第四檢測器18，用於檢測第四上部輸送 機17運送的單板是否到達所設定位置。 如上所述，在第四上部輸送機17的七個吸引裝置4z

8的檢測訊號，加 以控制各吸斗4a的開閉閥4b的動作。 並與第一實施例相同，還設有上、下移動自如的輥 50 ° e 第四實施例如上述所構成，以下從第17圖實線所示 各構件及各單板的狀態，依序說明一連串的動作： 首先，第三吸引構件組4B的S區域、U區域及W區 域的全部開閉閥4b爲關閉狀態。 第一下部輸送機1，運送與第一實施例相同狀態及形 狀的多張單板2k、2m…，沿輸送方向最下游側的單板2k 的下游側端部被第一單板檢測器6檢測到。 於是，從第一單板檢測器6向控制機構發送檢測訊號 • ，接收到該訊號的控制機構發出使得各構件按如下方式動 作的訊號。 也就是使得氣缸4c動作，以使得S區域的開閉閥4b 一起旋轉到開放狀態。 結果，單板2k與第一實施例相同，如第18圖所示， —起被吸引上升到第四上部輸送機17側，並與輸送帶 12c壓接，同時，以速度vl朝箭頭方向被輸送。 在由該輸送帶12c輸送單板2k中，如同第一實施例 ，從控制機構依序發出動作訊號，使得在單板2k通過處 -28- 201026585 ’以及單板2k將要到達前，將吸引裝置4z的開閉閥 設爲開放狀態，通過結束處的吸引裝置4z的開閉閥4b 爲關閉狀態。 不久，單板2k如第19圖所示，其沿運送方向下游 端部由第四檢測器18檢測到。此時，S區域及U區域 吸引裝置4z的開閉閥4b如圖成爲關閉狀態。 接收到來自上述第四檢測器1 8的檢測訊號的控制 Ο 構向W區域的吸引裝置42的氣缸4C發出訊號，使得 閉閥4b —起旋轉到關閉狀態。 於是，單板2k與第二實施例相同，因其本身重量 下’如第20圖所示，換移到運出輸送機19，此後，藉 運出輸送機19，以速度vl朝箭頭方向輸送。 另一方面，在第一下部輸送機1，單板2k沿運送 向上游側的單板2m，即使到達第四上部輸送機1 7的S

機構發出使得氣缸4c動作的訊號，使得S區域的吸引 置4z的開閉閥4b —起旋轉到開放狀態。 4b 設 側 的 機 開 落 由 方 區 送 斜 送 制 裝 -29- 201026585 其結果’單板2η如第21圖所示，一起朝著第四上部 輸送機17側被吸引上升，與輸送帶12c壓接，同時，以 速度vl朝箭頭方向運送。 接著’單板2n到達第22圖所示位置，以與單板2k

第五實施例的目的與第一實施例相同，但是，是在沿 運送方向相鄰單板之間無間隔狀態下，將藉由輸送裝置吸 ® 引單板上面運送的多張單板，不會施加拉伸力地移到支承 單板下面的輸送裝置。 如第23圖所示，第五上部輸送機20 (圖示省略真空 裝置4f等）設有第四吸引部4c’如圖所不，該第四吸引 部4c沿單板運送方向設有多個與第一實施例相同的多個 排列而構成的吸引裝置4z。 與第一實施例相同，輸送帶21c用於運送由第四吸引 構件組4c的吸引裝置4z吸引單板，將輸送帶21c架設在 帶輪21b和設在單板運送方向上游側的帶輪（沒有圖示） -30- 201026585 上，隨時以速度vl移動。另外，將第五檢測器22設在圖 示位置，用於檢測輸送帶21c輸送的單板的沿運送方向端 部到達所設定的位置。 第二下部輸送機23是設在第五上部輸送機20下方。

置4z所吸引的單板，將輸送帶26c架設在帶輪26b和設 在單板運送方向下游側的帶輪（沒有圖示）上，隨時以速 參 度v2移動。另外，將第六檢測器27用於檢測輸送帶26c 輸送的單板沿運送方向端部到達所設定位置。 控制機構（沒有圖示）接受來自第五檢測器22及第 六檢測器27的檢測訊號，根據來自控制機構的動作訊號 ，控制各構件動作。 其中，在第五實施例中，不設置輥50。 第五實施例如上所述’以下從第23圖實線所示各構 件及各單板的狀態，依序說明一連串的動作。 Φ 在第23圖的狀態下，第五上部輸送機20的第四吸引 構件組4c的全部吸引裝置4Z的開閉閥4b成爲開放狀態 ，與第一實施例相同狀態及形狀的多張單板2k、2m、2η …一邊被吸引，一邊運送。 第二下部輸送機23的第五吸引構件組4d的全部吸引 裝置4z的開閉閥4b成爲關閉狀態。 在該狀態下’單板2k、2m、2n…進一步被運送，單 板2 k的沿運送方向下游側端部由第五檢測器2 2檢測到， 並發出檢測訊號，控制機構接受該檢測訊號，發出動作訊 -32- 201026585 號，根據該動作訊號，進行下面動作： 如第24圖所示，從第五檢測器22位置，朝著運送方 向上游側，將三個吸引裝置4z的開閉閥4b設爲關閉狀態 ，同時，將第五吸引構件組4d的全部吸引裝置4z的開閉 閥4b設爲開放狀態。 於是，上述三個吸引裝置4z吸引單板2k上面的吸引 力消失，同時，由於第五吸引構件組4d的吸引裝置4z的 ❹ 吸引以及本身重量，單板2k朝下方移動，如第24圖所示 ，與輸送帶24c壓接。 其結果，單板2k以速度v2朝箭頭方向運送，並且， 根據與該運送相對應，來自控制機構的動作訊號，從第五 吸引構件組4d的通過結束處的吸引裝置4z依序使得開閉 閥4b成爲關閉狀態。 接收到第五檢測器22的上述訊號的控制機構經極少 時間後，如上所述，單板2k與輸送帶24c壓接後，發出 ® 動作訊號，第四吸引構件組4c的設爲關閉狀態的上述三 個吸引裝置4z，從運送方向上游側，與下一單板2m到達 一致，依序將開閉閥4b設爲開放狀態，如第25圖所示， 吸引單板2m的上面繼續運送。 當該單板2m也被第五檢測器22檢測到，則與單板 2k執行相同的動作，與輸送帶24c壓接，如第26圖所示 運送。 這樣，由第五檢測器22檢測到單板依序由輸送帶 24c輸送，與第一實施例相同，例如，單板2k和單板2m -33- 201026585 沿運送方向形成間隔。 由輸送帶24c運送的單板，若前單板的沿運送方向下 游側端部被第六檢測器27檢測到，則接收到該訊號的控 制機構發出動作訊號，將第六上部輸送機25的第六吸引 構件組4e的關閉的吸引裝置4z的開閉閥4b —起設爲開 放狀態。 其結果，如第27圖所示，單板2k被吸引上升與輸送 〇 帶26c壓接，同樣以速度V2運送。此後，順序與單板2m 、2n…相同，與輸送帶26c壓接，在沿運送方向形成間隔 狀態下，以速度v2運送。 雖然沒有圖示，本實施例也可以如在第六吸引構件組 4e的沿運送方向下游側，在三個並列設置吸引裝置4z處 ，設置與第一實施例相同的強制落下構件5、堆積台1〇 等構件，並與第一實施例相同地進行堆積。 當然，可以不使用第六上部輸送機25，由第二下部 • 輸送機23沿運送方向運送具有間隔的單板，並用公知的 堆積裝置支承單板下面進行堆積。例如從第二下部輸送機 23，將各單板送入沿著與運送方向垂直方向隔開間隔配置 的兩根桿上，以支承單板下面，並從該狀態使得上述桿沿 著互相離開方向移動到不支承單板的位置，使得單板以本 身重量落下堆積。 在第五實施例中，即使單板從第五上部輸送機20移 到第二下部輸送機23,從第二下部輸送機23移到第六上 部輸送機25，在單板上也不產生拉伸力，因此不會發生 -34- 201026585 破裂。 以下’說明本發明的其他可實施的方法： (1 )在第一至第四實施例中，以吸引裝置4z吸引單 板使其上升時，也可以從單板下方對單板整體一起朝上方 噴出空氣。 例如，在第一實施例的第一下部輸送機1的輸送帶 的下方，跨越單板整體，配置送風斗，使得用於吸引 〇 單板上升的吸引裝置4z的開閉閥4b作開放動作，同時， 從送風斗對單板整體一起朝上方噴出空氣，即能在短時間 使得單板上升。 (2 )在第一實施例中，第一單板檢測器6，檢測單 板到達第一吸引構件組4的應吸引處吸引，但是，也可以 在單板運送方向的上游側的位置預先檢測單板，藉由脈衝 計數器的距離檢測器檢測第一下部輸送機1的輸送帶1 c 的移動距離，於檢測單板到達應吸引處時吸引。 ® (3)在第一至第五實施例中，藉由吸引作用使得單 板從一輸送機移動到另一輸送機時，兩輸送機的間隔可以 根據真空裝置的能力，單板的重量加以適當調整，以達成 最佳的運送狀態。 本發明已以較佳實施例揭示如上，然其並非用以限定 本發明，任何所屬技術領域中具有通常知識者，在不脫離 本發明之精神和範圍內，當可作些許之更動與潤飾’因此 本發明之保護範圍當視後附之申請專利範圍所界定者爲準 -35-

In addition to the fifth, the first suction is also the first embodiment from the first single board to control the movement of each member from the solid line of Fig. 8. The three sides of the downstream side are attracted to the holding sheet, and the suction of the S area is a plurality of veneers of the lower conveyor 1. The delivery machine 9 is sent and detected along the upper end portion of the stacking table 10 by the second single-plate structure 8A so that the respective members operate t-side conveyor 9B -20- 201026585 and then 'make the corresponding cylinder 4c act so that the T-area exists The opening and closing valves 4b of the three suction devices 4 are rotated to the closed state to stop the suction of the suction devices 4z. As a result, as shown in Fig. 10, the veneer 2s is dropped by its own weight to the veneer group 2A which has been deposited on the veneer 1 1. On the other hand, the operation of falling onto the veneer group 2A φ as described above is performed simultaneously with the veneer 2s, and the operation of the subsequent veneer 21 is controlled as follows. That is, the plurality of veneers 2t, 2u, ... which are transported at the transport speed v1 by the first lower conveyor 1 at the transport speed v1 in the same state and shape as in the first embodiment are transported from the state 8 of the figure 8 to the S area. In the conveying direction thereof, the end portion of the downstream side of the veneer 2t is detected by the first veneer detector 6. Then, the detection signal is transmitted from the first board detector 6 to the control unit 8 A, and the control unit 8A that has received the signal issues a signal of the same operation as that of the first embodiment, so that the respective members operate. • As a result, the veneer 2t on the first lower conveyor 1 is made the same as the first embodiment, and is sucked up toward the second upper conveyor 9 side, and is crimped to the conveyor belt 9c, as in the 10th. As shown in the figure, the conveyance speed V2 of the conveyor belt 9c of the second upper conveyor 9 is immediately conveyed in the direction of the arrow. Next, the veneer 2t conveyed by the second upper conveyor 9 is moved toward the T region. As described above, 'corresponding to the movement of the board 2t, the control unit 8A receiving the signal from the first board detector 6 sends out the action signal sequentially after the preset time of the delay circuit is built in the control unit 8A. According to -21 - 201026585, this signal causes the components to operate as described later. In other words, the operation of each cylinder 4c is controlled, and the downstream conveyor 9B that has stopped is driven again, and the opening and closing valve 4b of the three suction devices 4z existing in the T region is moved in line with the veneer 2t, and is transported from the upstream side in the transport direction. The downstream side of the direction is sequentially rotated to an open state. As a result, as shown in Fig. 11, Fig. 12, and Fig. 13, the veneer 2t continues to be attracted to the second upper conveyor 9 side, and is transported to the upper side of the stacking table 10 in a crimped state, as if The board 2s is stacked on the board group 2A. In the S area, as in the first embodiment, the control unit 8A that receives the signal from the first board detector 6 sequentially sends an action signal via the delay circuit, and controls the operation of each cylinder 4c according to the action signal, and the board In response to 2t, the opening and closing valve 4b of the three suction devices 4z existing in the S region is sequentially rotated from the upstream side in the transport direction to the downstream side in the transport direction to the closed state. By performing the same action in reverse, it is possible to sequentially deposit a plurality of veneers which are transported in a state in which the first lower conveyor 1 is transported in the transport direction with almost no space between adjacent veneers. The description of the operation of the roller 50 is omitted, and it moves to each of the illustrated positions or stands by at the same time as in the first embodiment. The second embodiment is also the same as the first embodiment, and even if the veneer on the first lower conveyor 1 is transported by the second upper conveyor 9, no tensile force is generated in the transport direction of the veneer. The spacing between the boards can be increased along the transport direction. -22-201026585 In the first embodiment, when the veneer is stacked, the platen 5a of the forcible dropping member 5 is moved and stacked in a state in which the first upper conveyor 3 that transports the veneer is moved, but the first is made. The position of the veneer conveyed by the upper conveyor 3 and the operation time of the platen 5a are difficult to be completely the same every time the stacking operation is performed. Therefore, due to the difference in time, the positional error of the veneer leaving the first upper conveyor 3 along the transport direction is large, and the position in the transport direction that falls onto the veneer group 2A is offset and accumulated, sometimes in the After that, the φ process will become a problem. However, in the second embodiment, after the transfer of the downstream conveyor 9B is stopped, the veneer is dropped. Therefore, the stop position error of the veneer in this case is smaller than that of the first embodiment, and it falls to The positional shift in the transport direction on the single board group 2A also becomes small. In the second embodiment, the forced dropping member 5 may not be used, but if the forced dropping member 5 is used, the veneer is faster than the natural dropping speed, and the time required for the stacking can be shortened. To increase efficiency. Φ Hereinafter, a third embodiment of the conveying device of the present invention will be described. The third embodiment is transported in the same state as the first embodiment by the conveying means at intervals which extend the interval between the veneer and the adjacent veneers in the conveying direction. Fig. 14 is a partially cutaway side explanatory view showing the veneer conveying apparatus of the third embodiment, the first lower conveyor 1 being constructed in the same manner as the first embodiment, and the conveying belt 1c being moved at the conveying speed v1. On the other hand, the third upper conveyor 12 is disposed in place of the first upper conveyor 3 of the first embodiment. -23- 201026585 In the third upper conveyor 12, as shown, a second attraction member group 4A is provided, which is provided with a connection pipe 4t whose length in the direction in which the veneer is transported is larger than that of the first embodiment The connecting pipe 4d is shorter. Four suction devices 4z identical to those of the first embodiment are connected to the connecting pipe 4t. In the second suction member group 4A, as shown in the drawing, a motor 4e and a vacuum device 4f are provided in the same manner as the first embodiment. φ is the same as the first upper conveyor 3 in the third upper conveyor 12, and is composed of a rotating shaft 12a, a pulley 12b, a conveyor belt 12c, and a motor 3e, and the conveyor belt 12c is moved at a speed v2 at any time. On the downstream side of the third upper conveyor 12 in the transport direction, a conveyor 13 composed of a rotating shaft 13a, a pulley 13b, a conveyor belt 13c, and a suitable motor (not shown) is provided instead of the first embodiment. The stacking table 10 allows the conveyor belt 13c to move at a speed v2 at any time. The vicinity of the upstream end portion of the conveyor belt 13 c in the transport direction and the vicinity of the downstream end portion of the conveyor belt 12c in the transport direction are arranged such that the transport region is repeated in a short range and is spaced apart from the thickness of the veneer in the up and down direction. The wide spacing 〇 is the same as that of the first embodiment, and is provided with a roller 50 that is freely movable up and down. Further, a control mechanism 8B' is provided to control the operation of each member. The third embodiment is configured as described above. Hereinafter, a series of operations will be sequentially described from the state of each member and each of the boards shown in the solid line in FIG. 14 : First, the second suction member group 4A is along the upstream side in the board conveying direction. The opening and closing valve 4b of the three suction devices 4z is in a closed state, and the single plate 2χ-24-201026585 is sucked by the suction belt 12c while being sucked by the suction device 4z in which the opening and closing valve 4b on the most downstream side in the direction is open. It is moved to the conveyor belt 13c. In the first lower conveyor 1, a plurality of veneers of the same state and shape as those of the first embodiment are carried. From the state of Fig. 14, the first plate 2y, 2z.. is further conveyed by the first lower conveyor 1, and the downstream end portion Φ of the veneer 2y in the conveying direction is detected by the first veneer detector 6. To. Then, the detection signal is transmitted from the first board detector 6 to the control unit 8B, and the control unit 8B that has received the signal issues a signal for causing each member to operate as follows. That is, the cylinder 4c is immediately actuated so that the opening and closing valve 4b of the suction device 4z of the three second suction member groups 4A is rotated to an open state. As a result, the veneer 2y on the first lower conveyor 1 is identical to the first embodiment, as shown in Fig. 15, and is sucked up to the third upper conveyor 12 side, and is crimped to the conveyor belt 12c. . When most of the veneer 2x is shifted to the conveyor belt 13c, an operation signal for closing the opening and closing valve 4b of the suction device 4z located on the most downstream side in the veneer conveying direction is released from the control mechanism 8B to stop the suction. As described above, the veneer 2y which is crimped to the conveyor belt 12c is the same as the first and second embodiments, and the speed is changed from v1 to v2, and is conveyed at the third upper conveyor 12. Before the downstream end portion of the veneer 2y in the transport direction reaches the suction device 4Z located at the most downstream side of -25-201026585, a signal for causing the cylinder 4c to operate is caused from the control mechanism 8B, so that the opening and closing valve 4b is rotated to the open state. To make it attractive to the board. Then, as shown in Fig. 16, the veneer 2y is continuously conveyed while being pressed against the conveyor belt 12c, and soon, the veneer 2y is shifted to the conveyor belt 13c. On the other hand, corresponding to the movement of the single board 2y, the operation signals sequentially issued after the delay circuit of the control unit Φ 8B has passed through a predetermined time are the same as in the first embodiment, so that the opening and closing valves of the respective suction devices 4z are opened. 4b is rotated from the upstream side to the downstream side in the transport direction to the closed state so that the suction device 4z at which the veneer has passed does not attract. As described above, the third embodiment is also the same as the first embodiment. Even if the veneer on the first lower conveyor 1 is carried by the third upper conveyor 12, no tensile force is generated in the conveying direction of the veneer. Therefore, β can be transported while increasing the interval between the veneers in the transport direction. Next, a fourth embodiment of the conveying device of the present invention will be described. The purpose of the fourth embodiment is to change the transport path so that the first transport device transports the selected one of the plurality of veneers, for example, every other veneer, in the same state as the first to third embodiments. Shipped on a different shipping lane than the other boards. Figure 17 is a partially cutaway side view of the single-plate conveying device of the fourth embodiment.

On the other hand, a third suction member group 4B is provided above the first lower conveyor 1, and the same connection pipe 4d and vacuum device 4f as the first embodiment are omitted, and the third suction member group 4B is illustrated. There are seven suction devices 4z which are identical in composition to the first embodiment. As shown in Fig. 17, the rotating shaft 12a and the pulley 12b are disposed on the upstream side and the downstream side of the third suction member group 4B in the board conveying direction, respectively, and the conveyor belt 12c is placed by a motor (not shown). The conveyor belt® 12c is moved at a speed v1 to form a fourth upper conveyor 17» In addition, a fourth detector 18 is provided for detecting whether or not the veneer conveyed by the fourth upper conveyor 17 has reached the set position. As described above, the seven suction devices 4z' of the fourth upper conveyor 17 refer to the region of the three suction devices 4z on the upstream side in the transport direction as the S region, and the S region is along the suction device 4z on the downstream side in the transport direction. The area is called the ϋ area, and the area of the remaining three suction devices 4z is called the W area. In the W zone, below the conveyor belt 12c, and above the inclined conveyors 14-27-201026585, a carry-out conveyor 19 is provided which is moved at any speed in the direction of the arrow at a speed vl. Further, a control mechanism (not shown) is provided to control the operation of the opening and closing valve 4b of each of the suction buckets 4a based on the detection signals from the third detector 15 and the fourth detector 18 of the first single-plate detector 6. .

A series of operations: First, all the opening and closing valves 4b of the S region, the U region, and the W region of the third suction member group 4B are in a closed state. The first lower conveyor 1 transports a plurality of veneers 2k, 2m, ... in the same state and shape as in the first embodiment, and the downstream side end of the veneer 2k on the most downstream side in the conveying direction is used by the first veneer detector 6 detected. Thus, the first board detector 6 sends a detection signal to the control unit. The control unit that receives the signal issues a signal that causes the components to operate as follows. That is, the cylinder 4c is caused to operate so that the opening and closing valve 4b of the S region is rotated together to an open state. As a result, the veneer 2k is the same as the first embodiment, and as shown in Fig. 18, it is sucked up to the side of the fourth upper conveyor 17, and is crimped to the conveyor belt 12c, and at the same time, the speed v1 is directed in the direction of the arrow. delivery. In the transport of the veneer 2k by the conveyor belt 12c, as in the first embodiment, the action signal is sequentially sent from the control mechanism so that the suction device is applied before the veneer 2k passes the -28-201026585' and the veneer 2k is about to arrive. The opening/closing valve of 4z is in an open state, and the opening and closing valve 4b of the suction device 4z at the end is closed. Soon, as shown in Fig. 19, the veneer 2k is detected by the fourth detector 18 at the downstream end in the transport direction. At this time, the opening and closing valve 4b of the S region and the U region suction device 4z is in a closed state as shown. The control 接收 receiving the detection signal from the fourth detector 18 sends a signal to the cylinder 4C of the suction device 42 of the W region, so that the valve closing 4b is rotated to the closed state. Thus, the veneer 2k is identical to the second embodiment, and is transferred to the carry-out conveyor 19 as shown in Fig. 20 under its own weight, after which it is transported by the conveyor 19 at a speed vl in the direction of the arrow. . On the other hand, in the first lower conveyor 1, the veneer 2k is transported to the board 2m on the upstream side, and even if it reaches the S field of the fourth upper conveyor 17, the control mechanism does not emit the cylinder 4c. Signal. ® As a result, the veneer 2m is shifted from the first lower conveyor 1 to the inclined conveyor 14 as shown in Fig. 19. The veneer 2m continues to transport the veneer 2n along the upstream side in the transport direction. Further, the boards are transported by the first lower conveyor 1 and the tilting conveyor 14 from the state of Fig. 19, as shown in Fig. 21, the downstream side end of the single board 2m in the transport direction is used by the third single board detector. 1 5 detected. Then, the control unit that has received the detection signal from the third detector 15 emits a signal for causing the cylinder 4c to operate, so that the opening and closing valve 4b of the suction portion 4z of the S region is rotated to the open state. 4b Set the machine opening and closing by the square area to send the skewed package -29- 201026585 The result of the 'single board 2n as shown in Fig. 21, together with the fourth upper conveyor 17 side is attracted to rise, and the conveyor belt 12c Crimp, at the same time, at the speed vl in the direction of the arrow. Then, the board 2n reaches the position shown in Fig. 22, and moves to the transport conveyor 19 for further transport in the same manner as the board 2k, and the board 2p located on the upstream side of the board 2ri in the transport direction, and the board 2n The same is carried to the inclined conveyor 14. Ο Thereafter, the same action is repeated, so that the veneers conveyed by the first lower conveyor 1 are transported every other time in different transport lanes. The veneer transported to the W area by the fourth upper conveyor 17 is transferred to the carry-out conveyor 19, and as in the first embodiment, the forcible dropping member 5 provided with the press plate 5a can be used. The following describes the fifth embodiment of the delivery device of the present invention. The purpose of the fifth embodiment is the same as that of the first embodiment. However, in the state where there is no space between adjacent boards in the transport direction, the plurality of boards transported on the board by the transport device will be sucked. A stretching force is applied to the conveying device under the support veneer. As shown in Fig. 23, the fifth upper conveyor 20 (not shown in the vacuum device 4f, etc.) is provided with a fourth suction portion 4c' as shown in the figure, and the fourth suction portion 4c is provided in the veneer conveying direction. A plurality of suction devices 4z arranged in the same manner as in the first embodiment. As in the first embodiment, the conveyor belt 21c is for conveying the veneer by the suction device 4z of the fourth attraction member group 4c, and the conveyor belt 21c is erected on the pulley 21b and the pulley provided on the upstream side in the veneer transport direction ( Not shown) -30- 201026585 On, move at speed vl at any time. Further, the fifth detector 22 is provided at the position for detecting that the end of the veneer conveyed by the conveyance belt 21c reaches the set position in the conveyance direction end. The second lower conveyor 23 is disposed below the fifth upper conveyor 20. As shown in the figure, the second lower conveyor 23 and the fifth upper conveyor 20 have repeated conveying regions in the downstream side portion in the conveying direction, and the length of the repeated conveying portion is at least the same as the length of the veneer in the conveying direction. Φ As shown in the figure, a fifth suction member group 4d is provided in the second lower conveyor 23 (the vacuum device 4f is omitted), and the fifth suction member group 4d is provided with three suction devices 4z in the above-mentioned repeated conveyance region. Further, a suction device 4z is further provided on the downstream side in the transport direction, and is composed of a total of four arrays. The suction device 4z has the same configuration as that of the first embodiment, and the suction port faces upward. The conveyor belt 24c is for conveying the veneers sucked by the suction device 4z of the fifth suction member group 4d, and the conveyor belt 24c is placed on the pulley 24b and a pulley (not shown) provided on the downstream side in the direction in which the veneer is conveyed. Move at speed v2 at any time. The sixth upper conveyor 25 is disposed in the horizontal direction on the downstream side of the fifth upper conveyor 20 in the conveying direction, and above the second lower conveyor 23, as shown in the figure, the sixth upper conveyor 25 and the second lower portion The conveyor 23 has a repeated conveying area along the downstream side portion in the conveying direction, and the length of the repeated conveying area is at least the same as the length of the veneer in the conveying direction. As shown in the figure, in the sixth upper conveyor 25 (the vacuum-31 - 201026585 device 4f is omitted, etc.), a sixth attraction member group 4e is provided, and the sixth attraction member group 4e is repeatedly transported in the above-mentioned manner, The downstream side of the transport direction is provided with a plurality of suction devices 4z that are arranged in the same manner as the first embodiment, and the suction port faces downward. The conveyor belt 26c is for transporting the veneers attracted by the suction device 4z of the sixth attraction member group 4e, and is transported. The belt 26c is stretched over the pulley 26b and a pulley (not shown) provided on the downstream side in the sheet conveying direction, and is moved at a speed parameter v2 at any time. Further, the sixth detector 27 is used to detect that the veneer conveyed by the conveyor belt 26c reaches the set position in the conveying direction end. The control unit (not shown) receives the detection signals from the fifth detector 22 and the sixth detector 27, and controls the operation of each member based on the operation signal from the control unit. Among them, in the fifth embodiment, the roller 50 is not provided. The fifth embodiment is as described above. Hereinafter, a series of operations will be sequentially described from the state of each member and the respective boards shown by the solid line in Fig. 23. Φ In the state of Fig. 23, the opening and closing valve 4b of all the suction devices 4Z of the fourth suction member group 4c of the fifth upper conveyor 20 is in an open state, and a plurality of veneers 2k of the same state and shape as those of the first embodiment are provided. , 2m, 2n ... are transported while being attracted. The opening and closing valve 4b of all the suction devices 4z of the fifth suction member group 4d of the second lower conveyor 23 is in a closed state. In this state, the boards 2k, 2m, 2n are further transported, and the downstream end of the board 2k in the transport direction is detected by the fifth detector 2 2, and a detection signal is sent, and the control unit receives the detection signal. , Act No. -32-201026585, according to the action signal, perform the following actions: As shown in Fig. 24, from the fifth detector 22, toward the upstream side in the transport direction, the three open and close valves of the suction device 4z 4b is set to the closed state, and the opening and closing valve 4b of all the suction devices 4z of the fifth suction member group 4d is set to the open state. Then, the three suction devices 4z attract the attraction force on the veneer 2k, and at the same time, the veneer 2k moves downward due to the suction of the suction device 4z of the fifth attraction member group 4d and its own weight, as shown in Fig. 24. It is pressed against the conveyor belt 24c. As a result, the single plate 2k is conveyed in the direction of the arrow at the speed v2, and the operation signal from the control means sequentially causes the opening and closing valve from the suction device 4z at the end of the passage of the fifth suction member group 4d in accordance with the conveyance. 4b becomes off. After the control means for receiving the signal of the fifth detector 22 has been pressed for a small period of time, as described above, the board 2k is pressed against the conveyor belt 24c to emit a motion signal, and the fourth attraction member group 4c is set to be in a closed state. The three suction devices 4z are aligned with the next single plate 2m from the upstream side in the conveyance direction, and the opening and closing valve 4b is sequentially opened. As shown in Fig. 25, the upper surface of the suction veneer 2m is continuously conveyed. When the veneer 2m is also detected by the fifth detector 22, the same operation as that of the veneer 2k is performed, and the veneer 24c is crimped and transported as shown in Fig. 26. Thus, the fifth detector 22 detects that the veneers are sequentially transported by the transport belt 24c, which is the same as the first embodiment, for example, the veneers 2k and the veneers 2m - 33 - 201026585 are spaced apart in the transport direction. The board conveyed by the conveyor belt 24c, if the downstream side of the front board in the transport direction is detected by the sixth detector 27, the control unit that receives the signal sends an action signal to the sixth upper conveyor 25. The opening and closing valve 4b of the suction device 4z that closes the sixth suction member group 4e is always in an open state. As a result, as shown in Fig. 27, the veneer 2k is suction-lifted and pressed against the conveyance belt 26c, and is also conveyed at the speed V2. Thereafter, the order is the same as that of the veneers 2m, 2n, ..., and is pressed against the conveyance belt 26c, and conveyed at a speed v2 in a state where the conveyance direction is formed in a space. Although not illustrated, the present embodiment may be provided with the same forced drop member 5 and stacking table as the first embodiment, in the three suction side devices 3z disposed side by side in the transport direction on the downstream side in the transport direction of the sixth suction member group 4e. A member such as 1 , is stacked in the same manner as in the first embodiment. Of course, instead of using the sixth upper conveyor 25, the second lower conveyor 23 transports the spaced veneers in the transport direction and supports them under the veneer by a known stacking device. For example, from the second lower conveyor 23, the veneers are fed into two rods arranged at intervals in a direction perpendicular to the conveying direction to support the underside of the veneer, and from this state, the rods are moved away from each other. Move to a position where the veneer is not supported, so that the veneers fall down on their own weight. In the fifth embodiment, even if the veneer is moved from the fifth upper conveyor 20 to the second lower conveyor 23, from the second lower conveyor 23 to the sixth upper conveyor 25, no pulling occurs on the veneer Stretching, so it will not happen -34- 201026585 rupture. The following describes other methods that can be implemented in the present invention: (1) In the first to fourth embodiments, when the suction device 4z is used to attract the veneer to rise, it is also possible to face the entire veneer from below the veneer. Air is ejected. For example, in the lower portion of the conveyor belt of the first lower conveyor 1 of the first embodiment, the air supply hopper is disposed across the entire single plate, so that the opening and closing valve 4b of the suction device 4z for sucking the rise of the veneer is opened. At the same time, the air is ejected from the air hopper to the entire board as a whole, so that the board can be raised in a short time. (2) In the first embodiment, the first single-plate detector 6 detects that the veneer reaches the suction portion of the first attraction member group 4, but may also detect the position on the upstream side of the veneer transport direction. The single board detects the moving distance of the conveyor belt 1 c of the first lower conveyor 1 by the distance detector of the pulse counter, and attracts when the detecting board reaches the attraction point. ® (3) In the first to fifth embodiments, when the veneer is moved from one conveyor to another by suction, the interval between the two conveyors can be based on the capacity of the vacuum device and the weight of the veneer. Adjust it to achieve the best shipping status. The present invention has been disclosed in the above preferred embodiments, but it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the present invention is defined by the scope of the appended claims. 35-201026585 [Brief Description of the Drawings] Fig. 1 is a partially cutaway side elevational view of the apparatus of the first embodiment of the present invention.
