悪くない特性を有している。2. Description of the Related Art Conventionally, as a type of a depositing machine for sequentially depositing plate-like objects, the plate-like objects are sequentially carried into the depositing machine through various transport conveyors such as a piercing conveyor and a suction conveyor, and forced. The tip of the plate-shaped object by directly colliding with a fixed ruler arranged at a predetermined tip-deposited position in the process of falling freely or obliquely downward and accumulating. A method of depositing with constant regulation is known, and the structure is extremely simple and the deposition efficiency is not so bad.

めて困難であった。However, it is possible to directly collide the tip of the plate-like object with the fixed ruler in such a manner by depositing a solid plate-like object such as a plywood or a synthetic resin plate at a low speed. Only when loading into a machine, for example, when the plate-shaped object is a little firm, but the loading speed is high, or when the plate-shaped object is a soft thin plate material (for example, veneer veneer In the case of transporting paper in a direction orthogonal to the fiber), etc., a fatal phenomenon such as damage to the tip of the plate-like object or buckling of the middle part is likely to occur due to the collision, so It is difficult to deposit, and in other words, the tip of the plate-like object is slightly inclined with respect to the transport direction (in the actual process, due to factors such as a minute speed difference between the left and right sides of the transport conveyor). , The plate-like object is often transported at a slight angle), and the tip on either side If only have partial strikes the fixed ruler earlier, concentrated load on the narrow portion, so more easily the fatal phenomenon occurs, deposited by the format was very difficult.

形式とされている。Furthermore, as another form, in place of the fixed ruler in the above-mentioned form, a movable ruler held by an elastic member such as a spring so as to be elastically displaceable is provided, and the elastic member contracts to form a plate shape. The impact caused by the collision between the object and the movable ruler is buffered and absorbed, and the plate-like object is once dropped to a position posterior to the predetermined deposition position, and then the elastic force of the elastic member is utilized to move the movable ruler to the movable ruler. By re-moving the plate-like object in the opposite direction to the carrying-in direction together, a form in which the tip end deposition position of the plate-like object is regulated to be substantially constant is also known, which is superior to the above-mentioned form in high-speed compatibility, Moreover, the occurrence of a fatal phenomenon due to the inclination of the transporting posture of the plate-like object is reduced, and it is a correspondingly effective improvement type.

あった。However, as described above, in order to move the dropped plate-like object again in the direction opposite to the carrying-in direction, it is essential that the plate-like objects can slide smoothly. In the case of a soft thin plate material, the transmission of force from the front end to the rear end cannot be performed well, which causes a problem of buckling of the tip part or the middle part of the thin plate material to be re-moved, It is also difficult to deposit by the above-mentioned improved method, and after all, by acknowledging the deterioration of the deposition efficiency, the transport is temporarily stopped, and then it is dropped vertically to deposit, or the regulation is abandoned and it deposits randomly. However, all of them were practically unreasonable.

を提案する。The present invention was developed with further improvement so that even if a thin plate material is a little soft, the tip deposition position is regulated to a substantially constant value and efficient deposition is possible. However, specifically, it is usually waiting at a standby position that is in front of the predetermined tip deposition position, and whenever the thin plate material carried into the deposition machine is dropped diagonally downward, it is preferentially thinned. Non-reciprocating, which can move back and forth by contacting the tip of the plate
With a dynamic buffer ruler, it is always located at the designated tip deposition point,
A fixed ruler that finally abuts the tip of the thin plate material so that it replaces the buffer ruler that recedes when it comes into contact with the thin plate material, and a retracted buffer ruler each time the thin plate material falls below the buffer ruler. An intermittently actuated return mechanism for returning the sheet to the standby position, and a device for regulating the tip deposition position in a thin plate material depositing machine (claim 1), and the configuration according to claim 1. Accordingly, an apparatus (claim 2) is proposed in which the central portion of the cushioning ruler is slightly projected in the direction opposite to the direction in which the thin plate material is loaded.

が行い得る。According to the structure of claim 1, the thin plate material is
A part of the kinetic energy possessed is passed on to the buffer ruler that comes into contact first, and it comes into contact with the fixed ruler in the decelerated state, so even if it is a little soft, the fatal phenomenon described above is unlikely to occur.
Further, therefore, it is possible to carry in the thin plate material at a correspondingly high speed from the beginning, so that efficient deposition can be performed. Further, according to the structure of claim 2, even if the thin plate member is slightly inclined with respect to the conveying direction, a considerable part of the range from the tip to the central part on one of the left and right sides is almost one. Since the load is distributed by contacting the buffer ruler like this, the occurrence of a fatal phenomenon caused by the concentration of the load in a narrow area as in the past is alleviated, and finally Since the inclination is corrected by abutting against the fixed ruler, there is no possibility that the deposition posture deteriorates. Of course, if the thin plate is not tilted with respect to the transport direction, the central part of the plate will contact the cushioning ruler almost evenly and the load will be distributed, so it will be effective without any special problems. Deposition can take place.

However, according to the configuration of the regulating device according to the present invention, the thin plate materials are held by the buffer ruler that abuts first. Since a part of the energy is passed on and contacts the fixed ruler in a decelerated state, even if it is a little soft, the fatal phenomenon like when contacting the fixed ruler from the beginning as in the past is unlikely to occur. Therefore, since it is possible to carry in the thin plate material at a correspondingly high speed from the beginning, efficient deposition can be performed. Of course, since it can not be played at all, thin plate material
There is no risk of buckling the tip or middle of the
The ruler is a recoilless type, and the movable ruler is elastically displaceable.

Even if it is slightly inclined, a considerable portion (a portion corresponding to the two ruler plates on the right side in the example) within the range from the tip on one of the left and right sides to the central portion is almost even. Since the load is distributed by contacting with the, the occurrence of a fatal phenomenon caused by the concentration of the load in a narrow area as in the past is alleviated, and finally, the fixed ruler is also applied. Since the inclination is corrected by abutting against, there is no fear that the deposition posture deteriorates. Of course, as shown by the solid line, if the thin plate is not inclined with respect to the transport direction, the load will be distributed because the considerable part of the center part will almost uniformly contact the buffer ruler, so that the load will be distributed. Equally effective deposition can be carried out without hindrance.

の着脱により、調整可能とするのが好ましい。In the above embodiment, a single-row buffer ruler was used, but if necessary, it may be divided into a plurality of sheets in the conveying direction of the thin plate material, and usually between them. There is no problem with using a double-row cushioning ruler that provides an appropriate cushioning space to stand by, and is slidably supported as in the above embodiment, so that the kinetic energy transferred from the thin plate material is positively generated by friction. In addition to the form of consuming electricity, it is also possible to adopt a form in which it is slidably supported via linear motion bearings, etc., and is retracted with almost no resistance at least immediately after abutting with the thin plate material. It suffices that the shape of the thin plate member be in contact with the tip of the thin plate member and retractable so as to replace the fixed ruler, and the design may be changed appropriately regardless of the form of the above embodiment, but in any case, its own weight If there is an excess or deficiency in the Preferably to select on the basis of experiments, and if the self-weight of the sheet material is varied periodically, due removable of the weight, preferably adjustable.

It is preferable to select the interval between the tip deposition location where the fixed ruler is located and the standby location where the buffer ruler is waiting, also based on experiments.

である。Further, the form of the main body of the depositing machine is not limited to the form of the above-mentioned embodiment, and the point is that the thin plate material carried into a predetermined area via various conveyors or the like is dropped obliquely downward and deposited. For example, various conventionally known forms can be applied, and if necessary, by bending the thin plate material upward or downward in a direction orthogonal to the transport direction at the start of dropping, while improving rigidity in the transport direction. It is also possible to apply a depositing machine that uses a knockdown mechanism in which it is dropped obliquely downward.

材の堆積工程に於ける実施効果は極めて多大である。As is apparent from the above, according to the regulating device of the present invention, even if the thin plate material is a little soft, the tip deposition position can be regulated to be substantially constant and efficient deposition can be performed. Also, even if the tip of the thin plate material is slightly inclined with respect to the transport direction, the tip deposition position can be controlled without difficulty, so it has excellent applicability to actual processes and is suitable for the thin plate material deposition process. The implementation effect is extremely large.
