The extruding plate 44 has a tip portion divided into five in a comb shape. . Each of the comb teeth 44a is inserted between the respective vertical walls 25 of the L-shaped bucket 24 of the bucket conveyor 18 which is in a moving state facing the carry-out port 16, and the packaged articles stored in the five buckets 24a to 24e. 14, the articles to be packaged 14 are pushed laterally and slid on the transfer path 32 through the carry-out port 16 so as to be supplied in a state of being aligned with the carry-in end of the packaging machine 20.
[0025]
A cam follower 55 as an engaging element is attached to the slider 47 so as to protrude toward the inside of its orbit . The cam follower 55 connects the side frames 35 a on both sides of the machine frame 35 . The guide rail 61 is attached to and fixed to the bar 57. The guide rail 61 is for moving the slider 47 to the upstream side along the transport direction of the bucket conveyor 18 to guide the extrusion plate 44 to a predetermined extrusion start position.
[0026]
The guide rail 61 is attached to the upper side of the cross bar 57 and extends between the driving sprocket shaft 48a and the driven sprocket shaft 50a. The end 61a near the drive-side sprocket shaft 48a is close to the machine frame side plate 35a on the downstream side in the transport direction of the bucket conveyor 18, and the end 61b near the driven-side sprocket shaft 50a coincides with the position at which the extrusion plate 44 starts pushing. The cam follower 55 of the pushing means 37, which coincides with the upstream position in the transport direction and reverses from the forward path on the lower side of the machine frame 35 to the return path on the upper side thereof, comes into contact with it. That is, the slider 47 that moves on the return path is guided to the upstream side in the transport direction of the bucket conveyor 18, and the extruding plate 44 is returned to the predetermined extrusion start position.
[0027]
Further, as shown in FIGS. 9 and 10, the articles to be packaged 14 discharged from the bucket conveyor 18 are maintained in the aligned state on the transfer passage 32 from the carry-out port 16 to the carry-in end of the packaging machine 20. Positioning means 50 is provided at the carry-in end of the packaging machine 20 for positioning and supplying the product at a predetermined position. The positioning means 50 comprises two guide plates 52, 54 provided on both sides of the transfer passage 32 along the same. A guide plate 52 located on the forward side of the bucket conveyor 18 in the transport direction and provided on the side of the transfer passage 32 is linearly arranged.
[0028]
On the other hand, the guide plate 54, which is located on the rear side of the bucket conveyor 18 in the transport direction and provided on the side of the transfer passage 32, is covered from the rear end side of the carry-out port 16 in the transport direction toward the carry-in end side of the packaging machine 20. It is formed to be inclined forward in the transport direction of the bucket conveyor 18 by an amount corresponding to two thicknesses with respect to one width of the package 14.
[0029]
In the automatic accumulating and feeding apparatus 10 of the present embodiment configured as described above, the bucket conveyor 18 and the small wobble conveyor 34 are continuously operated in synchronization with each other, and the bucket conveyor 18 unloads and outputs the 15 packages 14 to be packaged. The endless chain 42 is rotated one revolution while being conveyed toward the endless 16, and three pushing operations are performed by three pushing means 37 attached to the endless chain 42 at equal intervals.
[0030]
That is, on the outward path in which the extruded plate 44 comes into contact with the articles to be packaged 14 and pushes them out toward the packaging machine 20, the extruded plate 44 attached to the slider 47 crosses over the bucket conveyor 18 at the tip end thereof. The comb teeth 48 enter between the vertical walls 25 of the buckets 24a to 24e of the bucket conveyor 18 and push the packaged articles 14a to 14e sideways. Then, as the bucket 24 moves, the vertical wall 25 abuts on the comb teeth 44 a side of the push plate 44. Then, the slider 47 slides on the slide bar 45 by receiving a thrust from the vertical wall 25, and the comb teeth 44 a move obliquely while sliding on the vertical wall 25 to move the packaged object 14 on the lateral transfer passage 32. The dirt is discharged obliquely while keeping the alignment. At this time, the corner of the rearmost packaged object 14e slides on the inclined guide plate 54 to prevent the alignment state from being disturbed. Thereafter, the five items to be packed 14a to 14e are linearly extruded toward the carry-in end of the packaging machine 20 by the extruding plate 44 and supplied thereto.
[0031]
Then, the pushing means 37 is reversed by the driving sprocket 48 and shifts to the return path on the upper side of the machine frame 35. In this return path, the cam follower 55 of the slider 47 comes into contact with and engages the guide rail 61, and the slider 47 and the pushing plate 44 keep their positioning guide rails until they are reversed again by the driven sprocket 50 and return to the forward path. Guided by 61, it is moved laterally toward the upstream side of the bucket conveyor 18 in the transport direction, and is returned to a predetermined extrusion start position in the transport direction.
[0032]
Therefore, as is clear from the above description, in the above-described embodiment, even if the articles 14 to be packaged are continuously transported by the bucket conveyor 18, 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.
[0033]
For this reason, it is not necessary to perform intermittent operation such as repeatedly starting and stopping the bucket conveyor 18, so that sufficient durability can be ensured even if the mechanical strength of the bucket conveyor 18 is not too large. Not only can the device be made smaller, but also the need for an intermittent drive mechanism can be eliminated, thereby reducing costs.
[0034]
In the illustrated embodiment, the guide rail 61 extends between the sprocket shafts 48a and 50a. However, the cam follower 55 is finally guided to a predetermined extrusion start position in the transport direction of the bucket conveyor 18. If possible, it may be shorter and the route along the way is not questioned.
[0035]
Further, in the automatic accumulating and feeding apparatus of the above embodiment, the case where the bucket conveyor is operated continuously is illustrated, but the present invention is also applicable to the case where the bucket conveyor is operated intermittently. That is, since the movement of the pushing plate 44 in the downstream direction of the bucket conveyor is obtained by the moving force of the vertical wall 25 of the bucket 24, the bucket conveyor 18 is intermittently operated at a high speed so that the bucket and the pushing plate interfere with each other. However, this can be absorbed by the movement of the extruding plate and the packaged object can be reliably pushed out to the side, and there is no trouble such as damage to them.
[0036]
FIG. 11 is a plan view showing a modification of the guide rail. As shown in the drawing, the guide rail 61 in this modified embodiment is composed of two guide rails 63a and 63b on the engagement start side and the disengagement side, and these two guide rails 63a and 63b are bent by pins 65. They are freely connected. The guide rail 63b on the engagement / disengagement side is rotatably attached to the cross bar 57 via a bolt 67, and the guide rail 69a on the engagement start side is formed by an elongated hole 71 and a bolt 69 formed in the guide rail 69a. It is slidably mounted on the crossbar 57.
[0037]
That is, with this configuration, the angle of the guide rail 63b on the engagement / disengagement side can be arbitrarily set and changed. By adjusting this angle, the pushing start position is changed according to the change in the number of articles to be packaged. Will be able to respond flexibly to changes in.
[0038]
【The invention's effect】
As described above in detail in the embodiment, according to the automatic accumulation and supply device according to the present invention, the movement of the extrusion plate in the downstream direction of the bucket conveyor is obtained by the moving force of the vertical wall of the bucket. Even if the conveyor intermittently operates at a high speed and the bucket and the extruded plate interfere with each other, or the articles to be packaged are continuously transported by the bucket conveyor, the articles to be packaged on the bucket conveyor facing the carry-out port are moved to the front end. It is possible to reliably discharge a predetermined number of products from each of them in a stacked state while being vertically aligned, and to supply them to the downstream side of the packaging machine.
[0039]
In addition, when the bucket conveyor does not need to be operated intermittently and is operated continuously, sufficient durability can be ensured even if the mechanical strength of the bucket conveyor is not excessively large. Not only can the device be made smaller, but also the intermittent drive mechanism becomes unnecessary, so that the cost can be reduced.
In addition, the guide rail is attached to the upper side of the crossbar connecting the two side frames on both sides of the machine frame on which the traction means is provided, and the engaging element that engages with the guide rail is provided inside the orbit of the slider by the slider. If it is made to protrude toward and attached, the mechanism for returning the slider of the pushing means to the predetermined pushing start position is arranged close to the traction means in the machine frame inside the orbit of the slider. Thus, the size of the yagra conveyor can be prevented and the size can be reduced as much as possible.
Further, the guide rail is composed of an engagement start side guide rail and an engagement / disengagement side guide rail, and these two guide rails are flexibly connected by pins, and the engagement / disengagement side guide rail is bolted to a cross bar. If the guide rail on the engagement start side is slidably mounted on the crossbar by a long hole and a bolt formed in the engagement start side, the guide rail on the engagement release side It is possible to arbitrarily change the setting of the angle of the guide rail, and by adjusting this angle, it becomes possible to flexibly cope with a change in the extrusion start position accompanying a change in the number of articles to be extruded.
