The insertion guide 4 is positioned slightly below the pusher 3b of the push arm 3 so that the side surface portion of the upper frame C2 with the needle contacts and is fixed to the machine frame 1 via the bracket 4a. Attached to.

  Further, the push-in arm 3 has a pusher 3b against the arm body 3c so that no load is suddenly applied to the upper frame C2 with the needle when the upper frame C2 with the needle of the needle rack is pushed toward the needle receiving lower frame C1. It is preferable that a spring spring 3d is interposed between the arm body 3c and the pusher 3b.

  On the left and right sides of the machine frame 1, the upper frame C2 with needles is positioned just above the lower frame C1 of the needle holder until the upper frame C2 with needles of the needle rack is pushed into the needle receiving lower frame C1 by the pushing arm 3. An upper frame support arm 6 is provided for holding the frame.

  The upper frame support arm 6 pushes the upper frame C2 with needles onto the needle receiving lower frame C1 after the leaf tobacco D is stacked on the needle receiving lower frame C1 set on the leaf stuffing work table B. The upper frame C2 with the needle is held at a position immediately above the needle receiving lower frame C1 until it is pushed in, immediately before the push-in arm 3 (the pusher 3b) comes into contact with the upper frame C2 with the needle (the shoulder C2 '). It is configured to be detached from the needle-attached upper frame C2.

  As a mechanism for holding the needle-attached upper frame C2 of the needle rack until just before the push-in arm 3 comes into contact, for example, the upper frame support arm 6 is moved inward from the left and right sides of the machine frame 1 in synchronization with the operation of the push-in arm 3. Various mechanisms are conceivable, such as a structure that protrudes and retracts. However, in the illustrated embodiment, the upper frame support arm 6 extends or bends in synchronization with the operation of the push-in arm 3 so that the needle is attached. The upper frame C2 is freely detachable.

  That is, as shown in detail in FIG. 4, the upper frame support arm 6 is formed to bend 90 degrees around the pivot pin 6a in the middle thereof, and the upper frame support arm 6 is extended within a certain range. In a certain range, it was supported by the support arm 6b so as to be bent, and the base end side 6c of the upper frame support arm 6 was fixedly attached to the machine frame 1 at a position below the push-in arm 3. A fixed projecting projection is provided at the center position of the rotating plate 10, and a connecting shaft 11 linked to the rotating plate 10 through a sliding connector 16 is connected to the lifting frame 5 that moves up and down in the vertical direction. The upper frame support arm 6 is configured to bend and extend as the rotating plate 10 reciprocates by 180 degrees via the connecting shaft 11 in accordance with the up-and-down movement of 5.

  Reference numerals 13a and 13b in the figure are springs for lifting the connection shaft 11 upward or pushing it downward, and reference numeral 12 indicates a rotation plate 10 for connecting the rotation plate 10 and the connection shaft 11. A coupling tool 14 projecting on the back side is a guide groove for guiding a guide roller 9 projecting on the opposite side of the coupling tool 12, and is formed on the surface of the elevating frame 5.

Next, leaf filling work using the main leaf filling auxiliary device A will be described.
As preparation for leaf filling work, the needle holder lower frame C1 of the needle rack is set at a fixed position on the work table B1 of the leaf filling work table B. At this time, the push-in arm 3 is in the lower limit position, and the upper frame support arm 6 is bent halfway and is in contact with the back side of the insertion guide 4. Therefore, the upper frame C2 with needle is directly above the lower frame C1 of the needle holder. The push-in arm 3 is moved upward by pushing the lift switch S1 so that it can be held in position (see FIG. 6A).

Then, the elevating frame 5 and the sliding connector 16 are lifted together with the pushing arm 3, so that the connecting shaft 11 is moved to the upper limit position by the elastic force of the spring 13a disposed above the sliding connector 16. Can be lifted. Then, the rotating plate 10 rotates rightward in the drawing, and the guide roller 9 protruding from the back side of the rotating plate 10 passes under the short guide piece 14a and enters the guide groove 14 (see FIG. 6 (b)), a straight line connecting the upper frame support arm 6 projecting at the center position of the rotating plate 10 and the guide roller 9 projecting from the peripheral edge of the rotating plate 10 is substantially vertical. As a result, the upper frame support arm 6 is supported and extended by the support arm 6b (see FIGS. 4 and 7A).
At the same time, when the operating element 5a protruding from the lifting frame 5 touches the upper limit stop limit switch L1, the lifting operation of the lifting frame 5 is stopped, and the pushing arm 3 stops at a predetermined height and enters a standby state. (See FIGS. 7A and 7B). Reference numeral S3 in the figure is a stop switch.

  After that, on the needle holder lower frame C1 set on the work table B1 of the work table B, the cigarettes D are aligned and stacked while applying the tip of the petal leaf to the backing plate B2 so as to be as uniform as possible. .

Next, the upper frame C2 with the needle is hooked over the upper frame support arm 6 which is supported by the support arms 6b on both the left and right sides of the machine frame 1 and is extended (FIGS. 5A and 7 (B). b)).
Then, as shown in FIG. 5 (a), the upper frame C2 with the needle is in contact with the insertion guide 4 and at the same time the upper side of the alignment guide piece C5 formed under the shoulder C2 '. When the frame support arm 6 is engaged, the frame support arm 6 is accurately positioned at the position directly above the needle receiving lower frame C1.

  When the upper frame C2 with the needle is hooked on the upper frame support arm 6, as shown in FIGS. 5 (a) and 7 (b), the alignment guide piece C5 is positioned on the needle receiving lower frame C1 side. It is preferable to set so as to be slightly engaged with the alignment guide piece C6.

Next, the lowering switch S2 is pushed to move the pushing arm 3 downward (see FIG. 8A).
Then, the elevating frame 5 and the sliding connector 16 are lowered together with the push-in arm 3, but at the initial stage of the lowering operation, the connecting shaft 11 is connected to the spring 13a disposed above the sliding connector 16. It enters the guide groove 14 while being lifted upward by the elastic force. As the lowering operation proceeds, the spring 13a disposed above the sliding coupler 16 loses the force to lift the coupling shaft 11 upward, and is disposed below the sliding coupler 16 at the same time. Since the connecting shaft 11 is pushed downward by the elastic force of the spring 13b, the guide roller 9 protruding from the peripheral edge of the rotating plate 10 passes over the short guide piece 14a and is disengaged from the guide groove 14. The rotating plate 10 rotates in the direction of the arrow t (see FIG. 8B).
Reference numeral 17b in the drawing is a guide projection for forcibly pushing the guide roller 9 in the guide groove 14 out of the guide groove 14.

  Then, as the lowering frame 5 further descends, the rotating plate 10 rotates leftward in the drawing, and the rotating plate 10 finally rotates approximately 180 degrees from the state of FIG. Then, since the upper frame support arm 6 loses the support of the support arm 6b and is in a state of being folded, the needle-attached upper frame C2 is released from the upper frame support arm 6 (see FIGS. 9A and 9B). ). At the same time, the guide roller 9 protruding from the back side of the rotating plate 10 passes under the short guide piece 14a and enters the guide groove 14 again (see FIG. 10).

As the elevating frame 5 is further lowered, the pusher 3b of the push-in arm 3 comes into contact with the shoulder C2 'of the upper frame C2 with the needle, and the upper frame C2 with the needle is pushed into the needle receiving lower frame C1. The leaf tobacco D stacked on the needle receiving lower frame C1 is skewered by a long needle C3 protruding from the needle-attached upper frame C2 side and the needle receiving lower frame C1 and the needle It is sandwiched and bound by the attached upper frame C2 (see FIGS. 11A and 11B).
At the same time when the push arm 3 reaches the lowering limit, the operation element 5a protruding from the lifting frame 5 touches the lower limit stop limit switch L2, so that the lowering operation of the lifting frame 5 stops and the pushing arm 3 stops. .

When the downward movement of the push-in arm 3 is stopped, the two are connected by the connecting tool C4 provided on both sides of the needle receiving lower frame C1 and the needled upper frame C2 (see FIG. 11B).
Thereafter, when the lift switch S1 is pressed, the push-in arm 3 moves upward, and when the operating element 5a protruding from the lift frame 5 touches the standby limit switch L3, the lift operation of the lift frame 5 is stopped. Return to the original position shown in a).

On the other hand, when the needle rack released from the push-in arm 3 is lightly pushed forward, the leaf tip support table B3 of the leaf filling table B is tilted by about 90 degrees, and the needle rack is lowered with the leaf tip side down accordingly. It tilts 90 degrees and is transferred to a lifting rail (not shown) of the lifting device.
