Next, an embodiment of a work stacking device (hereinafter referred to as the present device) according to the present invention will be described with reference to FIGS. 1 to 6. FIG. In this embodiment, it is assumed that very thin sheet-like works W such as drugs such as poultices, paper pieces, foils, films, and plastics are laminated, but for convenience of explanation, the figures are shown with thickness. ing.

As shown in FIG. 1, this apparatus has a transport mechanism 1 that transports a work W in a predetermined direction, a distribution mechanism 2 that distributes the work W being conveyed by the transfer mechanism 1 downward, and a distribution mechanism 2. A transport mechanism 3 that transports the works W distributed downward, a drum mechanism 4 that rotates and transports the works W transported by the transport mechanism 3 while adhering them, and a work W that has been rotationally transported by the drum mechanism 4. A stacking mechanism 5 for stacking is provided, and each mechanism is controlled by a control unit 6 .

In addition, as shown in FIG. 6, the present apparatus has two sets of independent distribution mechanisms, each consisting of a conveying mechanism 1, a distributing mechanism 2, a transferring mechanism 3, a drum mechanism 4 and a stacking mechanism 5 arranged in the vertical direction. A mechanism 2 , a transfer mechanism 3 , a drum mechanism 4 and a stacking mechanism 5 are provided along the conveying direction of the conveying mechanism 1 .

The conveying mechanism 1, as shown in FIG. 2, has two conveyor belts 11 arranged in parallel with each other in the width direction of the work W (vertical direction in FIG. 2) with a predetermined interval therebetween. A conveyor belt 11 moves in a predetermined direction (to the right in FIGS. 1 and 2) at high speed. The conveyor belt 11 moves the workpiece W in a predetermined direction (to the right in FIGS. 1 and 2) in a ceiling-suspended state as the conveyor belt 11 moves in a predetermined direction while sucking the upper surfaces of both ends of the workpiece W in the width direction. Sequentially convey at high speed.

The sorting mechanism 2, as shown in FIG. 3, includes a rotating body 21 formed in a substantially semi-cylindrical shape, and as shown in FIGS. , and positioned above the conveyor belt 11 .

The rotating body 21 has a curved peripheral surface 21a that curves in the conveying direction. It is assumed that the posture changes continuously.

Specifically, as shown in FIG. 4(a), the rotating body 21 shifts from a posture in which the peripheral surface 21a (central portion) faces straight up to a posture in which the peripheral surface 21a (central portion) faces diagonally upward on the rear side of the transport. It shifts to a posture facing right behind in the transport direction. Then, as shown in FIG. 4(b), the circumferential surface 21a is shifted from the position in which the peripheral surface 21a faces diagonally downward in the rearward direction in the transport direction to the position in which the peripheral surface 21a faces straight down, and then changes to the position in which the peripheral surface 21a faces diagonally downward in the forward direction in the transport direction. do. Further, as shown in FIG. 4(c), the circumferential surface 21a changes from the position facing straight forward in the transport direction to the position facing diagonally upward in the forward direction in the transport direction, and then faces straight up. , and then to the same position, repeating continuously.

Further, as shown in FIG. 4, when the peripheral surface 21a of the rotating body 21 is in contact with the transfer surface of the work W, the rotating body 21 contacts the peripheral surface 21a with the work W conveyed by the transfer mechanism 1. By pushing it downward while keeping it in contact, it is distributed to the drum mechanism 4 directly below.

Specifically, as shown in the right diagram of FIG. 4(a), the rotating body 21 has been transported by the transport mechanism 1 when the peripheral surface 21a is in a posture facing right behind in the transport direction. As shown in FIG. 4B, as the workpiece W rotates in synchronism with the conveyance of the workpiece W, the peripheral surface 21a contacts the upper surface of the workpiece W and moves the workpiece W. After being pushed downward, as shown in the left diagram of FIG. After contacting, the peripheral surface 21a moves away from the workpiece W.

When the peripheral surface 21a of the rotating body 21 is separated from the conveying surface of the work W, as shown in FIG. 21 and let it pass through as is.

The transfer mechanism 3, as shown in FIG. 1, is provided at a position below the rotating body 21 of the sorting mechanism 2, and has a main driving shaft 31 arranged in front of the transfer direction and a main driving shaft 31 arranged behind in the transfer direction. A driven shaft 32, an intermediate shaft 33 arranged between the main driving shaft 31 and the driven shaft 32, and a conveyor belt 34 wound endlessly between the main driving shaft 31, the driven shaft 32 and the intermediate shaft 33. , the conveyor belt 34 rotates clockwise in a predetermined transfer direction by a drive motor (not shown). The conveyor belt 34 moves in a predetermined direction while sucking the lower surfaces of the workpieces W distributed by the rotating body 21 of the distribution mechanism 2 so as to push the workpieces W downward. Transfer diagonally downward.

As shown in FIG. 1, the drum mechanism 4 includes a cylindrical drum 41 provided in front of the lower end of the transfer mechanism 3. The drum 41 is rotated counterclockwise by a drive motor (not shown). The drum 41 rotates and transports the work W transported by the transport mechanism 3 to the lowest point of rotation while successively adhering the work W transported by the transport mechanism 3 on the peripheral surface by an air suction method, an electrostatic method, or the like.

As shown in FIG. 1, the stacking mechanism 5 includes a stacking table 51 provided below the drum 41 of the drum mechanism 4, and is moved vertically and horizontally by a drive motor (not shown). The stacking table 51 sequentially stacks the works W that have been rotationally conveyed by the drum of the drum mechanism 4 . Note that 52 and 53 are claw members provided on the stacking table, and press the front end and rear end of the stacked work W. As shown in FIG.

The control unit 6 controls the conveying mechanism 1, the distribution mechanism 2, the transfer mechanism 3, the drum mechanism 4, and the stacking mechanism 5 via respective drive motors. As shown in FIG. 6, the control unit 6 controls two independent sets of the transport mechanism 1, the sorting mechanism 2, the transport mechanism 3, the drum mechanism 4, and the stacking mechanism 5 in the forward direction with respect to the transport direction. 6) and the rotating body 21 of the sorting mechanism 2 in the rear group (left group in FIG. 6) with respect to the conveying direction are different by 180 degrees. to control. That is, when the peripheral surface 21a of the rotating body 21 of the distribution mechanism 2 of the front group is in a posture facing directly downward, the peripheral surface 21a of the rotating body 21 of the distribution mechanism 2 of the rear group faces directly upward. While facing the posture, when the peripheral surface 21a of the rotating body 21 of the distribution mechanism 2 in the front group is in a posture facing directly upward, the peripheral surface 21a of the rotating body 21 of the distribution mechanism 2 in the rear group The surface 21a is oriented downward.

Thus, the rotating body 21 can alternately distribute a plurality of works W sequentially conveyed by the conveying mechanism 1 downward between the front group and the rear group. In this embodiment, the rear set of rotors 21 distributes odd-numbered works W downward, while the front set of rotors 21 distributes even-numbered works W downward.

Next, the flow of lamination of the works W will be described.

First, when an odd-numbered work W is transported by the transport mechanism 1, the work W is distributed downward by the rear set of rotating bodies 21, as shown in FIG. 6(a). After being transferred obliquely downward by the transfer mechanism 3 , the work W is rotationally conveyed by the drum of the rotating drum mechanism 4 and stacked on the stacking table 51 of the stacking mechanism 5 .

On the other hand, when an even-numbered work W is conveyed by the conveying mechanism 1, as shown in FIG. Distributed downward by the body 21 . After being transferred obliquely downward by the transfer mechanism 3 , the work W is rotationally conveyed by the drum of the rotating drum mechanism 4 and stacked on the stacking table 51 of the stacking mechanism 5 .

Efficient stacking is possible.

In this embodiment, the rotating body 21 of the distribution mechanism 2 is formed in a substantially semi-cylindrical shape, but may be formed in other shapes. However, it is preferable that a part of the peripheral surface 21a is formed into a curved surface so that the rotating body 21 gently contacts the workpiece W. As shown in FIG.

In addition, although the distribution mechanism 2 distributes the works W downward by the rotating body 21, it may distribute the works W downward by another mechanism.

In addition, although the transfer mechanism 3 is provided between the distribution mechanism 2 and the drum mechanism 4, the work W distributed by the distribution mechanism 2 is directly rotated and conveyed by the drum mechanism 4 without providing the transfer mechanism 3. good too.

Also, although the works W are alternately distributed by two sets of the distribution mechanism 2, the transfer mechanism 3, the drum mechanism 4 and the stacking mechanism 5, three or more sets of the distribution mechanism 2, the transfer mechanism 3, the drum mechanism 4 and the stacking mechanism 5 are provided. The works W may be alternately distributed by the stacking mechanism 5 .

Further, as shown in FIG. 7, for example, four sets of distribution mechanism 2, transfer mechanism 3, drum mechanism 4 and stacking mechanism 5 are provided, of which two sets of distribution mechanism 2, transfer mechanism 3 and drum mechanism 4 and the stacking mechanism 5 alternately sorting the works W to form two sets of stacks. The next two sets of stacks may be constructed by alternately distributing W. According to this, it is possible to alternately repeat the transfer of the other two sets of laminates to a different location while one of the two sets of laminates is being constructed, so that a plurality of sets of laminates can be separated. It becomes possible to deliver continuously to the process of

Further, in the present embodiment, the sorting mechanism 2, the transfer mechanism 3, the drum mechanism 4, and the stacking mechanism 5 are arranged in the vertical direction with respect to the transport mechanism 1. There may be. Even if the mechanisms are arranged in a direction other than the vertical direction, the direction in which the transport mechanism 1 exists is defined as the upper side, and the direction in which the stacking mechanism 5 exists is defined as the lower side.

Although the embodiments of the present invention have been described above with reference to the drawings, the present invention is not limited to the illustrated embodiments. Various modifications and variations can be added to the illustrated embodiment within the same scope as the present invention or within an equivalent scope.
