Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for transferring a quadrangular pallet having directionality to a flow to transfer conveyors having different flow directions.

Configuration of Conventional Example and Problems Thereof FIG. 1 shows a conventional conveying device in which a pallet is required to have directivity in the conveying direction. Reference numerals 1 and 2 are conveyors having different conveying directions, and 3 and 4 are rotatable by 90 ° about points p and q in the directions of arrows A and B so that the pallet always has directionality with respect to the conveying direction. A 90 ° reversing device equipped with a pallet pull-in / feed-out device, 5 is an intermediate conveyor, and 6 is a drop prevention stopper that keeps the pallet from falling while the reversing device 3 is rotating. As described above, the number of units that make up the transport device is large, and it is indispensable to connect the control devices that make up each unit and their connections, and the wiring becomes complicated.
It is easy to cause miswiring and failure, and since it is necessary to install a 90 ° reversing device and an intermediate conveyor on top of it, the cost is high, and the space between the conveyors 1 and 2 is wide and the installation area occupied by the entire system is narrowed. It was difficult and there was a problem as space saving of equipment.

OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks and is advantageous in reducing the cost of the entire equipment.

Configuration of the invention, the apparatus of the present invention, a first conveyor that conveys a quadrangular pallet having a direction to the flow of conveyance, and a linear second conveyor that conveys the pallet in a direction orthogonal to the first conveyor A conveyor group that is orthogonal to the second conveyor and has a conveyor third conveyor that is in the opposite conveyor direction to the first conveyor, and the first conveyor, the second conveyor, and the vicinity of the transition between the third conveyors, and these conveyors. Inside the space formed by the group, having the same tangential direction component as the conveying direction of the conveyor group, the outer peripheral surface of the turntable rotating while contacting the pallet, and the outer peripheral surface of the turntable pallet Sandwiching, the semicircular arc-shaped inner peripheral surface of the radius that enables the guide of the conveyance while maintaining the directionality of the flow of the pallet from the first conveyor to the third conveyor. Since it is a transfer device that is composed of a fixed guide that it has, it is possible to omit the reversing device and the intermediate conveyor unit that were conventionally required, which is advantageous for cost reduction, space saving of equipment, and improvement of equipment reliability. is there.

Description of Embodiments One embodiment of the present invention will be described below with reference to FIGS. In FIG. 2, 7 and 8 are first and third conveyors for conveyance having opposite conveying directions, and arrows f and g indicate the conveying directions. The quadrangular pallet 18 sent from the first conveyer 7 for transfer is transferred to the second conveyer 9 for transfer, and at the same time, receives a force in the direction of the arrow h, and on the outer peripheral surface D of the turntable 10, between the belt and the quadrangle pallet 18. It is pressed by frictional force. Since the turntable 10 is rotating in the direction of the arrow i, the product of the frictional force and the friction coefficient between the quadrangular pallet 18 and the turntable 10 receives a rotational moment about the point O of the turntable 10 to receive the quadrilateral pallet. The direction of 18 is converted from arrow f to arrow h. After that, at the same time as the transfer to the third conveyor 8 for transportation, the same action as described above occurs, so that the direction of the quadrangle pallet 18 is changed from the arrow h to the arrow g, and the directionality of the quadrangle pallet 18 is lost with respect to the flow. It is possible to migrate without any. The fixed guide 11 corrects the posture of the square pallet 18 during rotation of the square pallet 18 together with the turntable 10.

Further, the relationship between the turntable 10, the fixed guide 11 and the square pallet 18 will be described in detail. Assuming that the turntable 10 is rotating in FIG.
The frictional force with the belt of the works. Therefore, the frictional force between the turntable 10 and the square pallet 18 acts in the direction of arrow h. However, this force works in the opposite direction to the direction in which the turntable 10 rotates, so that the quadrangular pallet 18 receives a moment around the point r and rotates in the direction of the arrow 1 to move between the fixed guide 11 and the turntable 10. It gets stuck in a stuffed parenthesis. From the above, it can be demonstrated that rotating the turntable 10 is effective for preventing the fixed guide 11 and the turntable 10 from being caught and for changing the direction of the rectangular pallet.

In FIG. 4, the turntable 10 is fixed to a shaft 14 held by a bearing 13 contained in a main body 12 fixed to a plate 19. Shaft 14
The gear 15 is attached to the opposite side to which the turntable 10 is attached, and the power of the motor 16 is transmitted to the turntable 10 by the engagement of the gear 20 attached to the tip of the reduction gear 17 and the teeth 15. The turntable 10 can be rotated.

EFFECTS OF THE INVENTION As described above, according to the present invention, it is possible to smoothly change the direction of the pallet while maintaining the directionality of the pallet with the configuration of only the three conveyors, the turntable 10, and the fixed guide 11. It is particularly effective in saving space in equipment and improving reliability of equipment.
