Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION In the present invention, it is necessary to change the conveying direction of a conveyed object or to change only the direction of the conveyed object with respect to the conveying direction due to, for example, a structural limitation of a line layout or equipment to be used. BACKGROUND OF THE INVENTION The present invention relates to a production line, and more particularly to a directional change conveyance device used for a line of a bookbinding printed material or the like whose speed has been remarkably increased recently.

[0002]

2. Description of the Related Art In general, when a direction of a conveyed object is changed in a production line such as a bookbinding printed matter, the direction is changed in a state where one book or a predetermined number is stacked. Various types of devices for changing the direction have been developed. These conventional devices include a device for changing the direction of conveyance, such as connecting a curved conveyor or a straight conveyor with a drop at a right angle, and a device for changing only the direction of a conveyed object, such as a conveyance belt or a push pin. Various methods, such as those that use the speed difference between the two, that change the direction by directly hitting the transferred object against a guide, etc., and that change the direction during transfer while holding the transferred object in the state Things have been devised.

When a curve conveyor is used in a high-speed line, when the line speed is increased, the conveyed object is swung outward due to centrifugal force, and the conveyed object is scratched or bent at the exit of the curve conveyor. Would. A combination of linear conveyors is considered to be an effective means when the line speed is low, but when the line speed is high, the conveyed object jumps into the other conveyor. Is not preferred in terms of quality control. Also,
When a speed difference between a belt and a push pin is used, there are problems such as rubbing of a conveyed object with the belt and scratches due to edges of the belt and the pins. Further, when the above-described mechanism is employed, the behavior of the transferred object is not stable because the degree of freedom of the transferred object cannot be restricted. Also, in the case of the method of sandwiching the transported object, the transported object is lifted from the transport surface and rotated, so that an ideal transport mode is adopted for the transported object from the viewpoint of quality control. Therefore, it cannot handle high-speed lines.

As described above, in the conventional direction changing device provided on a bookbinding line, when used in a high-speed line, it is extremely difficult to change the direction in a stable manner without damaging the transferred object. It was difficult.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a directional change transfer device for stably changing the direction of an object to be transferred on a high-speed line without damaging the object. With the goal.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, a directional change transport device of the present invention transports an object to be transported at a high speed while tracking the object, and continuously changes the transport direction or the direction of the object to be transported. And a mechanism for changing the transfer direction or the direction of the transferred object comprising a rotatable member for holding the transferred object.

According to a directional change transport device of the present invention, in the directional change transfer device according to the first aspect, a rotatable member for sandwiching the transferred object is disposed on a rotating body at equal intervals, and And a second conveyor that transports the first and second conveyors in different directions.

FIG. 1 is a plan view showing an embodiment of a direction change mechanism comprising a rotatable member for holding an object to be transferred in a direction change transfer device of the present invention. A large number of clampers 01, which can be fixed or rotated, are arranged at equal intervals on the outer periphery of the rotating body 02, and these are disposed on the upstream first tracking conveyer for conveying the conveyed object traveling in the A direction and the conveying direction or the conveyed object. It rotates in synchronism with the downstream second tracking conveyor that travels and conveys in a different direction B. The basic operation is
Conveyed object 0 passed from the tracking conveyor of
3 are sequentially clamped and conveyed, rotation and other operations are performed, and then unclamping is sequentially performed on the second tracking conveyor, whereby the conveyance direction and the direction of the object 03 are continuously changed at high speed.

Next, the details of the clamper 01 will be described with reference to FIG. A member 04 slidable in the vertical direction on a transport surface disposed above and below the transported object 03 is mutually covered by an actuator or a cam disposed along the rotary body 02 in synchronization with the rotational movement of the rotary body 02. The transferred object 03 is pinched by sliding in a direction symmetric to the transferred object. Further, the clamper 01 is structured so as to be freely rotatable with respect to the rotating body 02. Like the clamp operation, the actuator or the cam arranged along the rotating body 02, or a belt stretched from the center of the rotating body 02, or the like. The chain 05 and the like rotate in synchronization with the rotation of the rotating body 02.

FIG. 2 is a plan view showing one embodiment of the direction changing mechanism of the direction changing conveyance device of the present invention applied to the case of turning by 90 degrees. This shows a case where the transport direction and the direction of the transported object 03 with respect to the floor surface are changed by 90 degrees when the packaged object 03 enters the apparatus from the direction A and exits the direction B. The transported object 03 that has entered from the direction A (FIG. 2A,
(B)) is clamped by the rotatable clamper 01 at the position C (FIGS. 2 (c) and 2 (d)), and the conveyed object 03 is moved to the position D (FIG. 2 (e)) by the rotation of the rotating body 02. The object is conveyed, and at the same time, the clamper 01 unclamps the object 03 (FIGS. 2F and 2G). By the way, clamper 01
Has a mechanism that rotates the same angle in the opposite direction with respect to the rotating body 02, it is possible to change only the transport direction at high speed without changing the direction of the transported object 03 with respect to the floor surface. Also,
When the clamper 01 is fixed with respect to the rotating body 02, the transport direction and the direction can be quickly changed by 90 degrees. further,
By changing the unclamping position to the position E, the transport direction and the direction of the transported object 03 with respect to the floor
It is also possible to change the degree. Further, by applying the above mechanism, it is possible to change only the direction of the transported object 03 with respect to the transport direction.
