The present invention relates to a veneer feeding device for supplying an intermediate veneer to a spreader roll, and a plywood assembly device capable of supplying front and back veneers placed above in conjunction with the supply of the intermediate veneer. In particular, the intermediate veneers are supplied in upper and lower double rows in view of the supply speed for the core veneer and the front and back veneers, and are selectively and alternately supplied to the spreader roll, and also alternately from the feeder. Continuous feeding is carried out, and horizontal direction control is performed by a cross conveyor midway through.Furthermore, each veneer of the core plate and front and back plates is fed vertically after being fed horizontally by contacting the vertical feeding roller with a pinch roller. This invention relates to a plywood assembly device that does the following.

The problem of efficiency due to the supply speed to the rolls is a technical issue to be solved, and specifically, the core plate veneer and
After the front and back veneers are fed horizontally, they are immediately changed direction by the vertical feed rollers as the pinch roller rises, and fed upwards to the spretzer by the chute, and below that, the middle veneers are alternately fed in double rows. By feeding the intermediate veneer sheets one by one using each chute conveyor that corresponds to the spreader roll, it is possible to speed up the feeding of the medium veneer sheets, improve workability and increase efficiency. It is an object of the present invention to provide an excellent composite structure device that is useful for the application of plywood manufacturing technology in the manufacturing industry.

である。<Means and actions for solving the problem> The medium veneers are sequentially and alternately fed by a switching conveyor fed from a feeder to stationary conveyors provided in upper and lower double rows via a swing device, and , during the transfer on the fixed conveyor, the upper surface is slid laterally by the attitude adjustment conveyor installed on the fixed conveyor and rotates in a direction perpendicular to the conveyance direction, and the regulation ruler is displaced laterally. The core plates, which are positioned and aligned in contact with the stacker, are stacked in advance on the stacker, and the chute conveyors installed in each stationary conveyor are regulated and controlled by the feeding device for the front and back veneers. The adhesive is applied to the roll, and the adhesive is applied onto the core board veneer or the front and back board veneers (in the case of three-layer plywood) on the stacker, and at this point one of the adhesives is applied. The direction of the shoot conveyor toward the spreader roll is released, and the other shoot conveyor is switched to the direction of the spreader roll, while the core plate veneer and front and back plate veneers, which have been fed sideways from the feeder, are fed sideways. As it advances on the rollers and its lateral edges are regulated by side stoppers, the pinch rollers rise to pinch the core plate and front and back veneers between each vertical feed roller.
It waits on the chute with its front edge regulated, releases the standby at a predetermined timing, and discharges and places it on the veneer of the stacker. The board feeding mechanism is located between the two, and the core plate veneer feeding mechanism is located above.

見合つてスタツカ5に放出載置される。 Therefore, the feeding speed of each veneer 6, 6 of the front and back plates, which are lightweight as a whole, is slow to match the feeding speed of the core plate veneer 6'', which is thicker and heavier than this, and the weight The large medium veneer 6' can be fed alternately and quickly in two stages, upper and lower.
As a result, from the spreader rolls 59, 59', the core plate veneer 6'' and the front and back plate veneers 6, 6 are continuously discharged and placed on the stacker 5 in proportion to each other.

いう優れた効果が奏される。<Effects of the Invention> As described above, according to the invention of this application, basically, the medium veneer is fed to the spreader roll and the adhesive is applied by continuous feeding from the feeder, and the medium veneer is switched. By using a swing device to alternately switch the conveyor to a multi-stage stationary conveyor for feeding, compared to the veneers for the front and back plates and the veneer for the core plate, the weight of the medium is greater than that required for adhesive application. Since the conveyance path of the veneer board is made multi-stage with two stages, upper and lower, it is possible to speed up the feeding of the middle board, so the feeding speed of the core board and the front and back veneers can be adjusted as quickly as possible. This has the excellent effect of promoting productivity improvement.

が泰される。 In addition, by providing a chute conveyor whose base end is fixed at the tip of each fixed conveyor and whose tip is directed toward and away from the spreader roll alternately, it is possible to transport intermediate plates in multiple stages intermittently. The effect of being able to alternately feed the plates to the spreader rolls together with the core plate veneer and the front and back plate veneers at a constant speed is achieved.

が奏される。 In addition, by providing an attitude adjusting rotor that applies a lateral movement force midway through the stationary conveyor of the medium veneer feeding device, the medium veneer is prevented from coming into contact with the side stopper during transfer. All the pieces are arranged in the same posture,
An excellent effect is achieved in that the adhesive is applied to the same position.
その場合、回転による側方移動を行うため、中
板単板の送給に何ら支障を与えないメリツトもあ
る。 In this case, since the lateral movement is performed by rotation, there is an advantage that there is no hindrance to the feeding of the intermediate veneer.

守管理がし易く、設置場所も多くとらない利点が
ある。 By installing the front and back plate veneer feeder on top of the middle plate veneer feeder, the structure mechanism and the spreader mechanism are combined into one plant, making the overall device more compact and easier to control and maintain. It has the advantage of being easy to manage and does not take up much space.

ト化が図れる効果がある。 In addition, the front and back veneers can be conveyed vertically by installing a vertical feed roller on the horizontal feed roller and raising and lowering the pinch roller between the horizontal feed rollers and immediately converting the front and back veneers to the vertical feed roller. This also has the effect of making the device more compact.
更に、横送り後、縦送り可能となるための横送

効果が奏される。 Furthermore, after the horizontal feed, the terminal end of the horizontal feed, which enables vertical feed, can not only be used to regulate the side edges, but also can be used as a detection position for feed conversion, producing an excellent effect.
