Description

[Detailed Description of the Invention] The present invention relates to a manual adjustment device for a fastener separating claw in a calender loosening machine, and is a device that is a partial improvement of Patent Application No. 148713 filed in 1982.

The separating and supplying device for fasteners according to the above application includes a fastener having a substantially U-shaped cross section with one short piece and the other long piece.
Insert the bent parts of the following fasteners into the bent parts of the front fasteners one after another, stacking them in large numbers, and place them on a main rail that slopes low at the front at an appropriate angle, allowing the weight of the fasteners to loosen them. The fasteners moving toward the machine are separated one by one by alternate insertion of a holding plate attached to two followers that abut the rotating cam and a separation needle, and then fed to the loosening machine. Work efficiency is improved because it is not necessary to feed one or more fasteners to the loosening machine at the same time.

However, there is no problem if the presser plate and separation needle always operate normally, but the cylindrical cam that operates the presser plate and separation needle rotates together with the rotating shaft that is driven by the motor, so if it is operated for a long period of time, the rotation of the motor and Due to expansion and contraction of the chain or belt connecting the shaft and other reasons, the timing at which the presser plate and separation needle operate may deviate from the timing at which the binding device operates.

In such a case, it has been discovered that it is inconvenient that the motor must be temporarily stopped and the sprocket must be manually rotated to rotate the rotary shaft to adjust the positional relationship between the presser plate and the separation needle.

The present invention is an adjustment device for manual fine adjustment as described above.

An embodiment of the present invention will be explained with reference to drawings. Fig. 1 is a side view of a calender loosening machine with one mounting plate 1 and guide plate 2 cut out, and a large number of U-shaped fasteners 3 as shown in Fig. 2 are connected in series. The fasteners 3 that are placed on the main rail 4 and move downward under their own weight are separated one by one by the separating device 5, and the separated fasteners are moved from the sub-rail 6 to the loosening machine 7, and then folded into the folding knife 8.
The calendar is tightened with the fastener 3 by other mechanisms.

As shown in FIGS. 3, 4, and 5, the separation device 5 has a rotating shaft 9. Groove 10 having sine curve displacement characteristics on the left and right sides of
At the same time, a cylindrical cam 11 having a cylindrical cam 11 is fitted and a key 11' is fitted, and an arc 12 with the cylindrical cam 11 as the center is equal to the diameter of the outer circumferential radius of the cylindrical cam, and the center of the arc is fitted into the groove 10 of the cylindrical cam. Two followers 14 of the same shape and size with protrusions 13
15 facing each other, the tip 16a of the separation needle 16 shown in FIG. 8 is fixed to the upstream follower 14 toward the fastener 3, and the presser foot shown in FIG. The tip 17a of the plate 17 is fixed with the tip 17a facing the fastener 3 side, and as the rotating shaft 9 rotates, the presser plate 17 is inserted into the U-shaped groove of the lowermost fastener 3 and separated as shown in FIGS. 3 and 4. The needles 16 alternately go in and out between the lowest end and the next fastener to separate successive fasteners 3 one by one and transfer them to the loosening machine 7.

Reference numeral 19 denotes a fixed tube fitted to the rotating shaft 9 on the outside of the bearing 18, and as shown in FIG.
At the same time, a blind hole 22 is opened in the axial direction around the shaft hole 20, and a spring 23 and a locking pin 24 are fitted into the blind hole 22, and the board 25 screwed into the screw hole 21 rotates. It is fixed to the shaft 9.

A sprocket 26 is rotatably attached to the rotating shaft 9 in contact with the fixed tube, and the sprocket 26 has a shallow pinning portion at the proximal end 27 on the surface that contacts the fixed tube 19, as shown in FIGS. 11 and 12. The locking pin 2 becomes deeper as it reaches 29.
The locking groove 28 of No. 4 is cut out and connected to the motor 31 with a chain 30.

Reference numeral 32 denotes a manual handle fixed by a boat 33 to a rotating shaft 9 protruding from the sprocket 26, with finger hooks 3 symmetrically arranged.
4 is provided in a protruding manner so that the rotating shaft 9 can be rotated by hand.

As described above, in the calender loosening machine equipped with a manual adjustment device, when the sprocket 26 is rotated by the motor 31, the latching pin 24 of the fixed tube 19 engages with the pinning part 29 of the sprocket 26, and the rotating shaft 9 rotates. Furthermore, the cylindrical cam 11 rotates to alternately project the followers 14 and 15 toward the fasteners 3, and the overlapping fasteners 3 are separated one by one by the holding plate 17 and the separation needle 16 and transferred to a loosening machine.

When a timing difference occurs between the operation of the presser plate 17 and separation needle 16 and the operation of the binding device, the manual handle 3
2 in the direction of rotation of the sprocket 26 to adjust the positional relationship between the separation needle 16 and the holding plate 17 independently of the sprocket 26, and then, at that position, attach the locking pin 24 of the fixed tube 19 to the pinned part 29 of the sprocket 26. Multiply.

In this case, a fixed tube 19 on which a locking pin 24 is removably installed is fixed to the rotating shaft 9, and a sprocket 26 is rotatably mounted adjacent to the fixed tube 19.
The latching pin 24 of the fixed tube 19 is inserted into the latching groove 28 whose proximal end is shallowly recessed and gradually becomes deeper as it reaches the pin holder 29.
Since the driving force of the motor 31 is transmitted to the rotating shaft 9, the rotating shaft 9 can be freely rotated in the direction of rotation of the sprocket 26, and therefore can be rotated by operating the manual handle 32. Rotate the shaft 9 appropriately and press the presser plate 1.
7 and the separation needle 16 relative to the binding machine can be finely adjusted as appropriate.

Therefore, there is no need to turn and stop the motor many times to make adjustments as in the past, and you can operate the manual handle while looking at the motor to make even the smallest adjustments. The machine is highly effective and practical.
