Description

  The present invention relates to an improvement in a plate-like body deposition method and a plate-like body deposition apparatus.

  Conventionally, a plate-like body is conveyed above a deposition position located at a substantially constant height through a holding conveyance mechanism that holds and conveys the plate-like body in the vicinity of both left and right ends in a direction orthogonal to the conveyance direction. A deposition method in which the plate-like body is sequentially deposited at the deposition position by releasing the holding of the plate-like body by the holding and transporting mechanism and dropping the plate-like body downward is known. A number of deposition apparatuses used in the above are also put into practical use, and specific examples of the holding and transporting mechanism will be described in detail later. For example, as illustrated in FIGS. A pair of left and right support rods a1 and a2 that can be provided, an operating mechanism d1 and d2 that reciprocally rotate the support rods a1 and a2, and a vehicle that is movably disposed directly above or near the support rods a1 and a2. A pair of left and right upper conveyors e1 and e2, the upper part Although not shown in the drawing, the holding and conveying mechanism 1 is not shown in addition to the holding and sliding mechanism 1 that is configured by using a rotation mechanism h or the like that intermittently rotates the feeding conveyors e1 and e2. Slidably holding and transporting mechanism that includes support rods a1 and a2 that can be reciprocated and reciprocated to the left and right sides, and a pair of left and right lower conveyors in place of the above-mentioned support rods A pair of left and right drop-off members near a pair of left and right piercing conveyors provided with a plurality of piercing members on the circumferential surface, for example, a holding and conveying mechanism of a holding and conveying type prepared so as to be retractable or reciprocally movable. A sticking and transporting type holding and transporting mechanism that can be moved up and down, and a suction and transporting type holding and transporting mechanism that includes a pair of left and right suction conveyors in place of the sticking conveyor, and the like.

  However, in this type of deposition method and deposition apparatus, the plate-like body is always dropped and deposited at the same deposition position by releasing the holding of the plate-like body by the holding and conveying mechanism simultaneously on the left and right. Therefore, while the deposition posture can be neat, there are defects that make it difficult to separate each plate later, when taking out the plate from the piles one after another, especially the plate For example, in the case of a non-integral plate-like body, such as an assembly of a group of small-width veneer veneers such as unjoined fixed-size veneer veneers, separation of each sheet may be significantly complicated. Occurs.

Therefore, as disclosed earlier in “Veneer Single Plate Deposition Device” (Japanese Utility Model Publication No. 52-30785), the applicant of the present application passes through a rotating mechanism to the upper surface of the elevating and lowering deposition table provided at the deposition position. Equipped with a base that can reciprocate to the left and right (right and left in the direction orthogonal to the veneer veneer transport direction), and transports the veneer veneers (including the veneer veneer group) that have been cut to the upper position to drop them. Proposed a new method to receive the veneer veneer alternately at two different deposition positions by adopting a configuration in which the base is alternately reciprocated to the left and right via a rotating mechanism each time. As a result, the inventors succeeded in facilitating the removal of the veneer veneer in the subsequent process.
Japanese Utility Model Publication No. 52-30785

  However, since the method of the publication is configured to reciprocate the entire piles of the plate-like bodies sequentially deposited on the base, the reciprocating mechanism is not only required. As the deposition progresses and the weight of the sedimentary mountain increases, there is a weakness that makes it difficult to move back and forth quickly from side to side. It is necessary to reduce the sedimentary mountain frequently by suppressing the maximum sedimentation height of the sedimentary mountain to a low level. As a result, the system is becoming unsuitable for increasing the speed of recent deposition processes.

The present invention was developed to eliminate the weaknesses of the above-mentioned publication method, and with a simple structure, the plate-like body is always stably provided every appropriate number of sheets (basically, every sheet). However, if necessary, an improved deposition method and a deposition apparatus are proposed so that they can be dropped alternately to different deposition positions. Specifically, the plate-like body is positioned above the deposition position located at a substantially constant height via a holding conveyance mechanism that holds and conveys the plate-like body in the vicinity of both left and right end portions in the direction orthogonal to the conveyance direction. A plate-like body deposition method for sequentially depositing the plate-like bodies at the deposition position by releasing the holding of the plate-like body by the holding and conveying mechanism after being transported to and dropping the plate-like body downward, The holding of the plate-like body by the holding and conveying mechanism is alternately held on the right and left sides for every appropriate number of sheets , and later, only during the period when either one of the left and right sides of the plate-like body that has been released first reaches the deposition position. The plate-like body is deposited by delaying the opening time on the side of opening the plate-like material to drop the plate-like bodies alternately to different deposition positions every appropriate number of sheets (Claim 1). If, transportable to above the deposition location holds Te at the plate-like body left and right end portions near the conveying direction and perpendicular direction At the same time, by releasing the holding of the plate-like body above the deposition position, the holding conveyance mechanism that sequentially drops the plate-like body to the deposition position and the plate-like body that is dropped at the deposition position are directly Indirectly or indirectly, the stacking table that can be moved up and down, which is always received at a substantially constant height, and holding the plate-like body by the holding and transporting mechanism alternately on the left and right every appropriate number of sheets, and the holding is released first. The holding and releasing operation by the holding and conveying mechanism is controlled separately for each of the left and right sides of the plate-like body so as to delay and release the release timing on the side that releases the holding later only during the period when either one of the left and right sides reaches the deposition position. A plate-like body deposition apparatus comprising a control mechanism (claim 2) is proposed.

According to the deposition process or method of deposition apparatus according to claim 2 according to claim 1, the holding of the plate by the holding transport mechanism, to the left and right alternately every several sheets suitable, even Thus, a specific time period (previously In other words, the position of the side surface of the plate body is separately aligned with a simple configuration that is delayed and opened only by either the left or right side of the plate body that has been held open. With a simple configuration that does not need to be performed , regardless of the increase in the weight of the piles as the deposition progresses, the plate-shaped bodies are always alternately and differently arranged (every two places). It can be dropped to the deposition position, and it is not necessary to remove the deposition mountain frequently by suppressing the maximum deposition height of the deposition mountain, so that it can be adapted to speeding up the recent deposition processing. Become. If the release timing of the holding of the plate-like body by the holding and transport mechanism is excessively different on the left and right, the re-restoration of the holding of the subsequent plate-like body is excessively delayed, and the next deposition process may be delayed. However, in the present invention, it is sufficient to change the left and right opening times for the specific period, so that the re-restoration of holding is not excessively delayed.

  Hereinafter, the present invention will be described in further detail together with an example of the embodiment illustrated in the drawings. However, the holding and transporting mechanism used in the deposition apparatus has a basic configuration excluding a specific operation mode in which the right and left opening times are alternately different for every appropriate number of sheets. With regard to the above, since various forms known in the art including the above-described forms can be used, only one representative form is illustrated and described in detail, and the other forms are illustrated and described in detail for convenience. Omitted. In addition, the form of the mechanism for carrying the plate-like body into the deposition apparatus, the form of the mechanism for carrying out the pile pile of the plate-like body from the deposition apparatus, etc. are clearly specified, and various forms known in the art may be specified. Similarly, illustration and detailed description are omitted.

  FIG. 1 is a schematic side view of a plate-like body deposition apparatus according to the present invention, and FIG. 2 is a schematic back view of the plate-like body deposition apparatus illustrated in FIG. In the figure, reference numeral 1 denotes a pair of left and right support rods a1 and a2, fluid cylinders and cams, which are provided so as to be able to rotate and retract to both sides symmetrically, via support arms b1 and b2, support shafts c1 and c2, etc. And a pair of left and right upper mechanisms movably disposed immediately above or near the support rods a1 and a2 and the operation mechanisms d1 and d2 for reciprocally turning the support rods a1 and a2 to both sides symmetrically. Conveying conveyors e1, e2, servo motors, motors with clutches and brakes, etc., and rotating the upper conveying conveyors e1, e2 intermittently in the direction of the arrows in the figure via the rotation shaft g, pulley f, etc. A holding-sliding holding and transporting mechanism configured by using a mechanism h or the like, and based on the control of the control mechanism 6 described later, the rotation mechanism h and the operation members d1 and d2 are operated in a timely manner, It is carried in via the carry-in conveyor 3 The plate-like body 4, after the conveyed upward deposition location, to release the holding of the plate-like body 4, dropping the plate-like body 4 downwardly.

  Reference numeral 2 denotes an elevating table provided so as to be movable up and down in the direction of the arrow, and the plate-like body 4 falling from the holding and conveying mechanism 1 is directly moved up and down based on the control of the control mechanism 6 described later. Or indirectly through the bed 5 or the pile 4A or the like of the plate-like body, and is always received at a substantially constant height.

Reference numeral 6 denotes a control mechanism. In the normal state, the upper transport conveyors e1 and e2 are caused to travel and rotate in the direction of the arrow in the drawing via a rotation mechanism h and the like, and a detector 7 composed of a reflective photoelectric tube or the like. In addition to controlling the upper conveyance conveyors e1 and e2 to stop running for a while (at least until the holding of the plate-like body 4 is released) every time the plate-like body 4 reaches above the deposition position. , each time reaching the upper part of the plate-like body 4 is deposited position, via an actuating mechanism d1 · d2, etc., to right and left alternately supporting rod a1 · a2, Thus also, the plate-like body having an open holding a certain time period (previously The left and right sides of the upper side of the conveyors e1 and e2 are resumed when the holding of the plate-like body 4 is further released. At the same time, the support rods a1 and a2 are moved to the initial clamping position. It controls to dynamic return. Further, based on the detection signal of the detector 8 composed of a reflective photoelectric tube or the like, each time the plate-like pile 4A reaches a height exceeding a predetermined limit, the elevator 2 is lowered by an appropriate amount so that the pile position is determined. It is controlled so that it is maintained at a substantially constant height.

The deposition method according to the present invention is performed using, for example, a deposition apparatus configured as described above. The operation mechanism will be described in detail in order. The control mechanism 6 is carried in via the carry-in conveyor 3. Each time the plate-like body 4 is nipped and transported by the support rods a1 and a2 and the upper conveyors e1 and e2, and the tip reaches the position of the detector 7, the upper conveyors e1 and e2 are stopped for a while and A1 and a2 are controlled alternately so as to be rotated and retracted to both sides alternately by delaying a specific period. For example, as illustrated in FIG. 3, the last processed order (not shown) On the other hand, the support rod a2 is first rotated and retracted to the side, and one side of the plate-like body 4 is preferentially dropped to the deposition position, and then dropped for a specific period, that is, preferentially dropped. It is enough time for one side of body 4 to reach the deposition position After delaying, as illustrated in FIG. 4, the remainder of the support rod a1 is rotated retreated to the side, dropping the entire plate-like body 4 into the deposition position. And if holding | maintenance of the plate-shaped body 4 is open | released (even if it is before the fall of the whole plate-shaped body 4 falls to a deposition position, the time which does not inhibit fall), upper conveyance conveyor e1 * The travel of e2 is resumed, and the support rods a1 and a2 are controlled to return to their original clamping positions (see FIG. 2).

When the succeeding next plate-like body 4 is sandwiched and conveyed by the support rods a1 and a2 and the upper conveyors e1 and e2 and the tip reaches the position of the detector 7, this time, on the contrary, this is illustrated in FIG. As described above, the support rod a1 is first rotated and retracted to the side, and the opposite side of the plate-like body 4 is preferentially dropped to the deposition position, and then the plate-like body 4 is also preferentially dropped. Is delayed by a time period sufficient for one side to reach the deposition position, and the remaining support rod a2 is pivoted and retracted to the side as illustrated in FIG. 6, and the entire plate-like body 4 falls to the deposition position. Let Then, if the holding of the plate-like body 4 is released, the upper conveyors e1 and e2 are restarted, and the support rods a1 and a2 are controlled to return to their original clamping positions (see FIG. 2). . Furthermore, as illustrated in FIG. 5, each time the plate stack pile 4 </ b> A reaches a height exceeding a predetermined limit based on the detection signal of the detector 8 composed of a reflective photoelectric tube or the like, an appropriate amount of the lift 2 Control to lower.

Hereinafter, by repeating the same operation mode, the plate-like body can be alternately dropped to different (two places) deposition positions, and the removal of the plate-like body in the subsequent process is facilitated. Although the results can be achieved, as described above, according to the embodiment in which one side of the plate-like body is preferentially dropped to the deposition position, and the remaining one side is dropped to the deposition position in accordance with FIG. As is clear from FIG. 6, the plate-like body falls so that the remaining one side falls down, starting from the dropping position on one side of the plate-like body that has fallen to the deposition position first, and then drops following. Therefore, even if the position of the side surface of the plate-like body is not aligned separately, it is possible to deposit alternately at different deposition positions with high accuracy as desired. Te, configuration compared to the method of Sakiki publication not only is simple, the progress of the deposition Regardless of the increase in the weight of the sedimentary mountain, the deposition process can always be performed stably, and it is unnecessary to remove the sedimentary mountain frequently by suppressing the maximum sedimentary height of the sedimentary mountain to a low level. It is possible to adapt to the speeding up of the deposition process.

  In the above-described embodiment, the plate-shaped body is alternately dropped to a different deposition position for each sheet as basic. However, if necessary, the control mechanism can be controlled in two modes. By changing to the form that repeats the same control every time, it is possible to drop it to a different deposition position every two or more sheets, or it is possible to alternately change every three sheets. It is also possible to take a control form to drop to the deposition position.

Regardless of the form of the holding and transporting mechanism used in the deposition apparatus, if the release timing of holding the plate-like body by the holding and transporting mechanism is excessively different on the left and right, the subsequent holding of the plate-like body will be resumed. There is a possibility that the next deposition process will be delayed due to excessive delay, but as is clear from the above embodiment, the difference between the left and right opening times in the present invention is that the plate-like body on the side where the holding has been released first. This is a short-time difference that is sufficient for the end of the plate to reach the deposition position, so that the subsequent re-restoration of the plate-like body is not excessively delayed.

  Moreover, in the said Example, although the integral plate-shaped object was illustrated, as a plate-shaped object made into the object of a deposition process, like the unjoined fixed scale veneer single board disclosed by the above-mentioned gazette A non-integral plate-shaped body may be used.

  Although not shown in the drawings, at least in the deposition apparatus of the above-described embodiment, when necessary, the support rod comes into contact with the side surface of the dropped plate-like body when it returns to the initial clamping position. In addition, it is possible to further regulate the deposition posture of the plate-like body by additionally attaching a regulating plate for moving the plate-like body slightly inward from the dropping position to each support arm, support shaft, etc. .

  As is apparent from the above, according to the plate-like body deposition method or plate-like body deposition apparatus according to the present invention, not only an integral plate-like body but also a non-integrated plate-like body is particularly troublesome. Since it can be dropped and deposited alternately at different deposition positions for every appropriate number of sheets, it can be used for various plate-like body deposition processing processes that require removal of every appropriate number of sheets in the post-processing process. Can be used.
