DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a work transfer capable of erecting a long work such as a joist constituting a floor panel, which can save labor in assembling the floor panel, Regarding the standing device.

[Problems to be Solved by Prior Art and Invention]

2. Description of the Related Art In recent years, so-called panel construction houses in which floors, ceilings, etc. are formed using panel bodies have become widespread.

Such a panel body is often formed by bridging a long work such as joists and swords in a frame.

Further, when assembling the panel body, in order to stably supply the work having a rectangular cross section, it is desirable that the wide surfaces thereof are stacked and placed on the supply shelf. For convenience, it is often necessary to raise and deliver a wide surface.

Conventionally, such standing work has been performed manually, but manual work is inferior in work efficiency and safety, and makes continuous supply of work difficult. Moreover, since the panel body is formed of various modules according to the purpose of use, it is necessary to appropriately change the number of works to be supplied, and there is a problem to be solved such as further burdening the operator.

The present invention is based on the use of a plurality of juxtaposed upright machines, and is intended to provide a work transfer and erecting apparatus that can automate the uprighting of works, achieve labor saving and safety improvement, and enhance productivity. There is.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the work transfer and erection device of the present invention comprises a base arranged near a plurality of supply devices for supplying and removing the work and juxtaposed in the lateral direction. A transfer frame capable of reciprocating in the lateral direction along the work take-out edge is provided, and the transfer frame is provided with a conveyer conveyor and a plurality of vertical elevators that are vertically juxtaposed at intervals. The supply device sequentially feeds a long work piece transversely to its longitudinal axis from the work take-out edge onto the conveyer conveyor, and the conveyer conveys the received long work piece upwards. It is composed of a plurality of parallel and horizontally circling endless strings that feed the longitudinal axis of the work in the longitudinal direction while being placed on the conveying surface formed by the upper surface of the traveling line, and the standing machine extends in the lateral direction. Can be raised and lowered An elevating frame, a rotator provided on the elevating frame and rotatably pivoted reciprocally within a range of 90 ° by a rotary shaft extending in a lateral direction, and the work provided on the rotator at all times. It has a receiving piece that projects toward the take-out edge, and a push piece that moves up and down toward the receiving piece and projects in the same direction, and at the raised position of the elevating frame, the receiving piece is horizontal and of the transport surface. And a holding member for receiving and sandwiching the work between the lower pushing piece and the upper pushing piece, and for raising the receiving piece in an upright state with the rotation of the rotator by 90 °, It is equipped with a control device that sequentially raises the elevating frame from the unloading side and sequentially receives workpieces.

[Work]

A transfer frame that can move the base in the horizontal direction, a conveyor for vertically feeding the work, and a plurality of vertical standing juxtaposed with the standing machine, the standing machine is a lifting frame that can move up and down,
And a holding device for holding the work and holding the work and a pressing piece in an upright state with the rotation of the rotator, and further comprising a control device for sequentially raising the elevating frame from the carry-out side to sequentially receive the work.

Therefore, it is possible to automatically stand up the work transferred by the transfer conveyor and the stand up machine, and save labor.
It can improve safety. Moreover, since the elevating frame of the erecting machine is sequentially raised by the control device from the unloading side and receives the work, a plurality of works can be efficiently erected.
