本考案は、セツトアツプ式自動小箱詰め機にお
けるサイドフラツプの折込みを確実に行うカート
ンのサイドフラツプ折込装置に関する。[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a carton side flap folding device that reliably folds the side flaps in a set-up type automatic small cartoning machine.
(従来の技術)
セツトアツプ式小箱詰め機によるカートンの製
函は、容器の自動供給のものは1ケ箱を水平方向
に供給して横から挿入する方式が広く用いられて
いる。(Prior Art) When making cartons using a set-up type small cartoning machine, a system in which containers are automatically fed is widely used in which one box is fed horizontally and inserted from the side.
この場合箱内への容器の挿入をスムースに行な
う為製函工程の途中で一旦サイドフラツプを外側
へ拡げてから容器を挿入し、その後、該サイドフ
ラツプをタツカで内側へ折り曲げて蓋をし製函す
る方法がとられている。 In this case, in order to smoothly insert the container into the box, the side flaps are expanded outward during the box manufacturing process, and then the container is inserted, and then the side flaps are bent inward with a tack, the lid is closed, and the box is manufactured. A method is being taken.
この場合、該サイドフラツプを容器挿入の為、

へ折り曲げるタツカの動作範囲を越えたものにつ
いてはフラツプの折曲げエラーを生じ製函の不良
を生じさせていた。 In this case, use the side flap to insert the container.
Similarly, even if the side flap is bent outward, the restoring force of the side flap may change due to variations in the paper quality depending on the manufacturing lot of the box, variations in the finishing of the top flap fold line, or changes in the temperature and humidity of the work environment. Some of the flaps do not return to their original shape, and some that exceed the operating range of the tacker for inward bending cause errors in folding the flaps, resulting in defective box manufacturing.
この関係を第8図A,Bにより説明する。 This relationship will be explained with reference to FIGS. 8A and 8B.

該フラツプを捉えることが出来ず製函ミスを起し
ていた。 Figure 8A shows the case where the opening degree of the side flaps is normal, and since the side flaps are within the range of motion of the tack, which makes intermittent circular arc movements along the direction of movement of the box, the tack is synchronized with the movement of the box. The flap is folded inward by grasping the flap and pushing in from behind the flap, and at the end of the tacking operation, the flap is pushed to the folding reference point, thereby being guided into the guide and folding the upper flap. However, as shown in FIG. 8B, when the opening of the guide flap exceeds the operating range of the tapper, the tapper cannot grasp the flap, resulting in a mistake in box manufacturing.

The drive shaft 2 is configured to move in an arc around the center point O of the drive shaft 2. A linear slide rail A is fixed to the side surface of the tack bracket 3. Further, two sliders 5 that slide linearly are inserted in series on the slide rail 4, and a tassel cover 6 is fixed thereto with bolts.

A cam follower 11 made of a bearing that slides smoothly on the inner surface of the groove of the cam 10 is mounted in a direction perpendicular to the cam follower 11 with its axis in a direction perpendicular to the longitudinal direction of the cover 6. A tack tip 9 made of an L-shaped member is provided in the mounting hole of the tack cover 6.

できる巾寸法の溝13があけられている。 Reference numeral 10 denotes a cam, which is an L-shaped flat plate mounted on a plane perpendicular to the axis of the drive shaft 2, and has a groove 13 having a width that allows the outer peripheral surface of the cam follower 11 to slide along the shape of the flat plate. It's open.

戻る略円弧軌跡になつている。 The shape of the groove 13 extends outward with respect to the semicircular arc drawn around the axis O of the drive shaft 2 from the starting point of the tacker 12 operation with respect to the radius dimension of the arc, and approximately
The maximum extension length is at the position rotated to the right by 45 degrees,
At the end point of the tacking 12 operation, the trajectory is a substantially circular arc returning to the dimensional position of the circular arc.

て製函が出来る様になつている。 By configuring the cam 10 in such a shape, by operating the cam 12 from behind the side flap 8 of the box 7, the movement locus of the tip of the tack can be reliably captured even when the side flap 8 is opened too far to the outside. At the end of the operation, the tip of the tack tip 9 returns to the folding position of the box 7, thereby making it possible to form the box.

同期して駆動軸2が間欠回転運動をなす。 Next, the operation will be explained. As mentioned above, the side flap tacker 12 is provided parallel to and facing the boxes 7 which are continuously supplied on a bucket cart (not shown) or the like. The drive shaft 2 performs intermittent rotational movement in synchronization with the feeding of the box 7.
すなわち、前記末製函の、横倒ししてバケツト
に載せられた箱7がタツカ12に近づいてくる
と、該駆動軸2はこれと同期して箱の供給より速
い速度で右に回転し始める。 That is, when the box 7, which is the unfinished box and is placed on the bucket cart and placed on its side, approaches the tack 12, the drive shaft 2 starts rotating to the right in synchronization with this at a faster speed than the feeding of the box.

される。 In this case, the tip of the tip 9 is connected to the drive shaft 2.
The tactile tip 9 is attached to the cam mechanism 1 via linear slide mechanisms 4 and 5 to the tactile bracket 3 which rotates in a circular motion due to the rotation of the cam mechanism 1.
3 is attached to the tatsu cover 6 that slides on it,
As the drive shaft 2 rotates, the tip of the tactile tip 9 rotates in a substantially circular arc following the trajectory of the cam 10.

なされる。 In other words, the cam trajectory follows the side flap 8 of the box 7.
The tip of Tatsuka Chip 9, which performs the folding operation, begins to turn in a state extending toward the box 7 from the beginning of the operation, and approximately
At the position rotated 45 degrees to the right, the guide flap 8 of the box is extended to the maximum extent in the radial direction, and the box is opened too much.
Since the cam shape is such that it returns to the folding point of the side flap 8 at the end of the operation, the tactile tip 9
Since the side flaps 8 turn along this direction, folding of the side flaps 8 is ensured. After the folding operation is completed, the drive shaft 2 is driven in reverse rotation to return to the original operation starting point 9, and the next box 7 to be supplied is prepared.

た。(Effects) As described above, according to the present invention, the locus of the action of the tacker that performs the folding operation of the side flap can be extended to the rear of the side flap, and then return to the original length at the folding point. Since the cam is provided, the side flaps can be reliably folded even if the restoring force of the flaps varies due to differences in the paper quality of the box. For this reason, it was possible to eliminate the occurrence of defective products due to errors in the side flap box manufacturing.
