[0028]
In the automatic accumulating and feeding apparatus 10 of the present embodiment configured as described above, the bucket conveyor 18a and the wicker conveyor 34 are continuously operated in synchronization with each other, and the bucket conveyor 18a transfers the 15 packages 14 to the carry-out port 16. The endless chain 42 is rotated once while being conveyed to the endless chain, and three pushing operations are performed by three pushing means 37 attached to the endless chain 42 at equal intervals. Since the cam follower 55 attached to each of the pushing means 37 is engaged with the guide rail 59 of the machine frame 35, the slider 47 of each pushing means 37 is guided by the guide rail 59 as it makes one revolution with the endless chain 42. The reciprocating movement is also performed in the transport direction of the bucket conveyor 18a.
[0029]
That is, on the outward path in which the push plate 44 comes into contact with the articles to be packaged 14 and pushes them out toward the packaging machine 20, the cam follower 55 of the slider 47 is mounted on the skew guide rail 63 a attached to the lower side of the cross bar 57. The slider 47 and the pushing plate 44 are engaged with each other during the interval between the bucket conveyors 18b, and are moved to the downstream side in the transport direction of the bucket conveyor 18a in the section traversing the bucket conveyor 18a at the transport speed equal to the transport speed.

The slider 47 and the pushing plate 44 are guided by the positioning guide rails 61a and 61b and laterally moved toward the upstream side in the transport direction of the bucket conveyor 18a before being returned to the forward path by the sprocket 50 again. Is returned to the predetermined extrusion start position.
[0031]
Therefore, as is clear from the above description, in the above-described embodiment, even if the packaged object 14 is continuously conveyed by the bucket conveyor 18a, the packaged object 14 on the bucket conveyor 18a facing the carry-out port 16 is removed. It is possible to reliably discharge a predetermined number (5 pieces) of the front end portion side by side in a stacked state while being vertically aligned, and to supply it to the subsequent wrapping machine 20 side at a reference position. it can.
[0032]
Therefore, it is not necessary to perform the intermittent operation such that the bucket conveyor 18a is repeatedly started and stopped, so that sufficient durability can be ensured without taking the mechanical strength of the bucket conveyor 18a too large, and the bucket conveyor 18a can be secured. Not only can the device be made smaller, but also the need for an intermittent drive mechanism can be eliminated, thereby reducing costs.
[0033]
In the above-described embodiment, the positioning guide rails 61 are provided as a pair. However, the positioning guide rails 61 may be only the lower guide rails 61a on the paper surface shown in FIG. It is only necessary that the sheet can be finally guided to a predetermined extrusion start position in the transport direction of the bucket conveyer 18a, so that the route on the way is not questioned.
[0034]
Also, the skew guide rail 63 may be only the upper guide rail 63a on the paper surface shown in FIG. 4, and furthermore, only in the section crossing over the bucket conveyor 18a, the predetermined length of the extruded plate 44 corresponding to the transport speed is adjusted. The crossing start position (extrusion start position) and the crossing end position may be linearly connected and inclined.
[0035]
【The invention's effect】
As described above in detail, according to the automatic accumulation and supply device according to the present invention, even if the transporting unit continuously transports the packaged object, the packaged object on the transporting unit facing the outlet is provided. Can be reliably discharged sideways in a stacked state with a predetermined number of them from the front end in a vertically aligned state, and supplied to the downstream side of the packaging machine.
[0036]
This eliminates the need for the transport means to perform intermittent operation of repeatedly starting and stopping, so that sufficient durability can be ensured even if the mechanical strength of the transport means is not too large, and the size of the transport means can be reduced. Not only can this be achieved, but also the need for an intermittent drive mechanism is eliminated, so that the cost can be reduced.
In addition, the positioning guide rail is mounted on the upper side of the crossbar connecting the two side frames on both sides of the machine frame in which the traction means is provided, and the skew guide rail is mounted on the lower side of the crossbar, The engaging elements that engage with these guide rails are attached to the slider by protruding toward the inside of the orbit of the slider, so that a mechanism for reciprocating the slider of the pushing means in the transport direction of the transport means is provided in the traction means. The slider can be arranged close to the machine frame inside the orbit of the slider and can be arranged as small as possible, while preventing the yagur conveyor from becoming large.
In addition, by providing a pair of guide rails for positioning and skew for guiding the cam follower from both sides, the extruding plate of the extruding means can be reliably moved along a desired line. be able to.
Further, from between the forward guide rails formed on the lower side of the machine frame to between the return guide rails formed on the upper side, or from between the return guide rails for the forward travel. By providing guide pulleys for guiding the cam follower of the pushing means toward the guide rails on the drive sprocket shaft and the driven sprocket shaft of the traction means, the reversing movement of the pushing means does not cause a lateral displacement. , Can be performed smoothly and reliably.
