Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is used for packaging equipment, and more particularly to a right-angle transfer device in a binding machine for newspapers and the like.

(Prior Art) In a conventional packaging facility, a wrapping machine for wrapping stacked newspapers and the like in a film and a tying machine for tying the objects to be packaged sent from the wrapping machine with a band are straight-line type. Are connected by a belt conveyor. However, the packaging machine and the binding machine may be connected to each other by a conveyance path that changes the direction at a right angle due to the arrangement. A right-angle transfer device a as shown in FIG. 5 is conventionally provided in such a transport path. The right-angle transfer device a can project from the conveying surface of the vertical feed conveyor b by making it orthogonal to the vertical feed conveyor b and the vertical feed conveyor b for feeding the articles s loaded from the packaging machine in the vertical direction. Side-feeding conveyor c ...
And a stopper e provided above the end of the vertical feed conveyor b with a slight gap d between the vertical feed conveyor b and the vertical feed conveyor b. When the article s to be packaged s is put into the vertical feed conveyor b, the article s to be packaged s is sent to the terminal end by the conveyance drive of the vertical feed conveyor b, and the vertical feed is stopped by the stopper e. Then, when the lateral feed drive and the ascending drive (see the position indicated by the chain line in FIG. 5) of the lateral feed conveyor c are carried out, the article to be packaged s is lifted from the vertical feed conveyor b and then carried out to the binding machine side or the like. It was

(Problems to be solved by the invention) However, since the object s to be packaged s is stopped by the stopper e while being vertically fed by the vertical feed conveyor b, the film f that wraps the object s to be wrapped s is As shown in the figure, since the cargo is jammed into the gap d under the stopper e, it is often impossible to laterally feed the packaged object s. Further, even if the film f can be immediately removed from under the stopper e, the posture of the object to be packaged s is disturbed with respect to the lateral feed direction, which is also a cause of transport failure in the next process.

In view of such conventional circumstances, the present invention shows that when the packaged object is turned at a right angle at the end portion on the vertical feed conveyor, the film encapsulating the packaged material in the gap d below the stopper e. It is an object of the present invention to provide a right-angle transfer device for a binding machine that does not slip.

(Means for Solving the Problem) The right-angle transfer device in the newspaper tying machine of the present invention is for carrying out the material to be packaged which is vertically fed by the vertical feed conveyor in the horizontal feed direction orthogonal to the vertical feed direction. The horizontal feed conveyor, which is located on the side of the vertical feed conveyor, is vertically movable between the retracted position lowered from the transport surface of the vertical feed conveyor and the lifted position raised from the transport surface. In the case where a stopper is provided above the end portion of the conveyor in the vertical feed direction with a slight gap maintained between the conveyor and the conveying surface of the vertical feed conveyor, the stopper that is going to enter the gap is provided near the stopper. For the packaging film of the package,
An air injection mechanism for ejecting air from below is provided.

(Operation) When the object to be packaged is vertically fed by the vertical feed conveyor, the film wrapping the object to be wrapped is separated from the stopper and the vertical feed conveyor by the air blown from the air jetting mechanism provided near the stopper. It is pushed up to the upper position away from the gap, and the transport obstacle caused by the film penetrating into the gap disappears.

Embodiment An embodiment of the present invention will be described below with reference to the drawings. The direction in this description is to the right in FIG.
The left is called the back, the feed from the left to the right in FIG. 2 is called the vertical feed, and the feed from the top to the bottom is called the horizontal feed.

The right-angle transfer device 1 shown in FIGS. 1 and 2 includes a double-row vertical feed conveyor 2 and a double-row horizontal feed conveyor 3 ...
And the stopper 4 as a main part.

That is, the right-angle transfer device 1 carries out an article S to be packaged which is vertically fed by the vertical feed conveyors 2 and 2 in a horizontal feed C direction orthogonal to the vertical feed L direction. The lateral feed conveyors 3, ..., 3 arranged on the sides of the vertical feed conveyors 2, 2 (see FIG. 2) are supported by, for example, one frame (not shown), The lifting mechanism (not shown) such as a cylinder device connected to the lower surface of the frame (not shown) can move up and down between the lifting position (shown by a chain line in FIG. 1) raised from the transport surface 5 of the above. It is provided.

Further, the stopper 4 is provided above the end portion (front end portion) of the vertical feed conveyors 2, 2 in the vertical feed direction L direction.
It is provided with a slight gap D between it and the transport surface 5. As the stopper 4, for example, a plate body having both side ends bent is used.

Further, an air injection mechanism 11 is provided near the stopper 4. The air jetting mechanism 11 blows air from below onto the front end of the packaging film F of the article S to be packaged, which is about to enter the gap D between the vertical feed conveyors 2, 2 and the stopper 4, so that the packaging film F Is to prevent the sneaking into the gap D. For example, one in which a plurality of nozzles 13 are connected to air holes provided on the upper surface of the header 12 is used. The air injection mechanism 11 is
Instead of this example, a structure in which an air ejection hole is formed in the upper plate of the air duct may be used. Further, the tip end hole of each nozzle 13 and the air ejection hole of the air duct are 4 mm to 5 mm.
It is preferable to form the same size. By the way, header 1
2 or a duct (not shown) is connected to an exhaust valve (not shown) such as a solenoid valve, and the exhaust valve is a packaging film F.
The opening operation is performed by a detection signal of a sensor (not shown) that detects the entry of the.

Next, the operation of the above embodiment will be described.

Vertical feed conveyors 2, 2 and horizontal feed conveyors 3 ...
3 is driven.

When the object S to be packaged is loaded onto the vertical feed conveyors 2 and 2,
As shown in FIG. 3, the object S to be packaged is subjected to a vertical feed L that advances from the solid line position to the chain line position.

When the front end of the packaging film F of the article to be packaged S is going to enter the gap D between the vertical feeding conveyors 2 and 2 and the stopper 4 by this vertical feed L, the gas is exhausted by the detection signal of the sensor that detects the entry of the packaging film F. The valve opens. Air from the exhaust valve is blown up from the nozzles 13 to the lower surface of the front end portion of the film F via the header 12. By this blowing operation, the front end portion of the packaging film F is pushed up to an upper position apart from the vicinity of the gap D, as shown in FIG.

Subsequently, when the horizontal feed conveyors 3, ..., 3 ... Are driven to move upward, the article S to be packaged is lifted from the transport surface 5 of the vertical feed conveyors 2, 2 by the horizontal feed conveyors 3 ,. It is carried out by driving the lateral feed C of the lateral feed conveyors 3 ,.

(Effects of the Invention) The right-angle transfer device in the binding machine of the present invention has a gap between the stopper and the vertical feed conveyor in the vicinity of the stopper that stops the article to be packaged such as newspaper at the terminal end in the vertical feed direction. Since an air injection mechanism for blowing air from below is provided for the packaging film of the article to be packaged into the package, the packaged object may cause a jam of the film such that the film dives into the gap. Is completely eliminated, and the posture is not disturbed in the transverse feed direction. Therefore, there is an excellent advantage that the workability of the transfer work by the right-angle transfer device is significantly improved.
