Next, the deflection transfer device 13 of the present invention will be described in detail with reference to Figures 8 to Bg. This deflection transfer device 13 is installed over the conveyor chain 4 from near the front end of the cassette conveyor 1o in a flat mfi forward direction, and has nine machine frames [6]. It is held slightly separated above the conveyor chain 4. A pair of endless chains 17 and 18 are provided in parallel along the longitudinal direction inside this machine frame [6], and finger members 19 as shown in Fig. 6 are attached to each endless chain at predetermined intervals. ing. That is, the finger member 19 consists of a block holder attached to the chain 17.18, a fin, and a guard claw 21, and the block holder has a bottle passage passing through a through hole 22 at one end thereof, as shown in FIG. is rotatably attached to the chains 17 and 18, and a roller holder protruding inward from the other end of the hook 2o is fastened by a screw 24 and rotatably supported. The middle lower part of the block holder has a concave notch U, and the bingo protruding from the chain 17, 18 fits into this concave notch 26, and the block holder rotates downward around the bin path by its own weight. Prevents movement and tilting. The finger claw 21 is bent into a 5-shape from the lower part of the bottle toward the center of the block. It is bent vertically downward.

The finger member 19 is constructed as described above, and when the endless chain 1y, is driven, the finger member 19 reaches the lower running part of the chain 17. It is designed to protrude downward from the lower opening of the frame [6] and travel.

One endless chain 18%, that is, the endless chain 18 on the front side in the conveying direction of the conveyor 10.

In the vicinity there is provided a guide array for the finger part i19. As shown in FIGS. 7 to 9, this guide device side consists of a swingable guide frame 4, an air cylinder 30 for driving this guide frame, and a fixed guide rail 31. I'm so excited. This guide frame 4 is formed in a tapered shape with a cross-section of 'P' shape, and a support shaft 32 installed on the back side of the guide frame 4 is rotatably supported by a bracket 33 properly fixed to the machine frame L6. . 119. There is a single V on the back side of guide frame 4.
A par blade is attached to the upper end of the lever U, and a nine-joint member frame is pivotally attached to the upper end of the lever U so that the piston rod of the air cylinder (equipment) can be easily attached. The air cylinder 79 is attached to one end of the bracket, and the guide frame 4 can be swung about the support shaft 32 by driving the air cylinder and extending and contracting its piston rod 35. Can be done. A fixed guide rail 31 is fixed to the machine frame 16 in front of the guide frame 4, and this fixed guide rail 31 is adjacent to the upper inside of the lower running path of the dress chain 1'8. and extends parallel to each other, and the rear end thereof has a tapered surface 311.
and is close to the front end of the guide frame 290.

The lower bent surface 29a of the guide frame 4 is bent into a U-shaped cross section. The roller 25 protruding inwardly from the finger member 19 is configured to run while being guided by the folded surface 29 when the finger member 19 runs close to the guide frame 4. As shown in FIGS. 4 and 117, K.

At the position shown by the solid line where the piston rod 3 of the air cylinder (equipment) is contracted = the lower bent surface 2 of the guide frame
The extension surface of 9a extends downward from the rear end tapered surface 31a of the rigid guide rail 31, so that the lower part of the finger member 19 attached to the chain 18 is bent downward from this guide and the frame 4. The fixed guide rail 31 passes through the turntable a.
, so that part of this roller runs on the same surface as the chain 18, and the six shifter pawls 21 protrude downward from the machine frame L6. On the other hand, at the position indicated by the dash-dotted line where the air cylinder (9) is extended,
The guide frame swings around its support shaft 32 in the direction of the arrow, and the extension surface of its lower bent surface 1 is on the same plane as the rear end tapered surface 31 & the upper inclined surface of the fixed guide rail 31. Position: Part of the finger that was torn on the chain 18, and part of the roller #l, is located here.
29O is guided by the downwardly bent surface 29& to reach the upper surface of the fixed guide rail 31. The member 1 is located at an inclined position with the 5KW-2 pin upward as shown by the dotted line in Fig. 4. The finger claws appear to be pulled up into the four-wire plane 16.

In the deflection transfer device 1 of the present invention, the piston yys of the air cylinder (capital) always occupies the contracted position, and therefore the guide frame is at the solid line position tic in FIG.
The nine-finger member 19 is attached to the se and q machine chains 3'1718 and protrudes downward from the machine frame 16, and runs diagonally across the y pair 10 for the cassette. After the cassette 9, which is the object to be packaged, is conveyed upward and met, one finger claw (ma-m) is ejected in the direction of travel and is brought into contact with the cassette 9, which is transferred onto the conveying chain 4 adjacent in the lateral direction. let As shown in FIG. 8, the running speed of the endless chains 17 and 18 (■.) is V.

When the angle of the endless chain 17.18 with respect to the conveyor lO is θ, y, cos #≧v1”. Therefore, when the 220 finger claws 211L, 2111 protrude and run to move the cassette 9 in one direction in the horizontal direction , the finger pawl 21& that comes into contact with the rear end surface of the cassette does not act as a pressing force against the cassette 9, but only comes into contact with the nine flaps, and the other finger pawl 211)
on the left in the direction of travel.

Acting on the surface, it is processed in the direction of movement, that is, lI! It is pressed and deflected towards the feed chain 4.

The air cylinder of the deflection transfer device 13 of the present invention is arranged in front of the holder 80 for storing the aforementioned manuals, etc., and is operated in response to a phototube device (not shown). When it is detected by this photocell arrangement that the sheet part l, instructions, etc. 6.6 are not being supplied normally, compressed air is supplied to the air cylinder 30 in response to this detection signal. As mentioned above, the guide frame 4 swings due to the extension of the piston rod.
The finger member 190 attached to the front endless chain 18 rotates into the single machine frame L6 and rises as shown by the dashed line in FIG. Therefore, since there is no finger claw 21b that presses the cassette containing the packaged items in the lateral direction from the Koshibear 1G, the cassette is sent forward by the conveyor 10 and is ejected from the front end of the Koshibear. It will be used again as a cassette for wearing.

As described above, according to the present invention, the packaging department and the items to be packaged are separated left and right and are continuously conveyed.

Normally, the packaged items are deflected and transferred to combine them with the wrapping materials, and in the event of an abnormality, only the selected packaged items can be discharged separately. (Not only can it be done ÷, but also can prevent defective packaging in advance,
It becomes possible to recirculate the discharged material to be packaged and subsequently supply it to the desired rounding of packaging.
