Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a separation and supply device for calendar binding metal fittings, which is capable of reliably separating each binding metal fitting placed on a rail in multiple layers and feeding it to a calendar binding machine. It is something.

The calendar binding fitting A has an insertion groove C formed by bending a folded piece B into a rectangular shape as shown in FIG.
The bent portions of the following binding fittings are sequentially inserted into the insertion grooves C, and the bent portions of the binding fittings are overlapped in large numbers and placed on the rail D of the feeding device as shown in FIG.

Since the binding hardware is constructed so that it descends on the rail by its own weight, the polymers of the binding hardware are often in close contact with each other, so in order to perform the binding process smoothly, it is necessary to remove the first binding hardware from the following. It is necessary to separate each sheet and supply it one by one in accordance with the operation of the binding machine F.

As shown in Fig. 9, a conventional separating and feeding device for binding metal fittings is such that a curved part G and a horizontal part H are formed at the tip of an inclined rail E, and a horizontal part H is formed at the tip of an inclined rail E, and the difference in angle between each part is used to separate and feed the leading part. A mechanism is used in which the binding metal fittings are separated one by one, sucked by a sucker J that swings like an arrow mark (■), and conveyed to the binding machine F.

However, in the above device, not only is the air system used for Soccer J expensive, but also the binding metal fittings cannot be separated smoothly and several binding metal fittings are conveyed to the binding machine F at the same time, or conversely, due to long-term use, If the suction cup J' is damaged, the binding metal fittings may not be transported.
Workability was extremely poor.

The present invention has been devised in view of the above, and the separating claw of the model is inserted into the gap between the first binding metal fitting and the second binding metal fitting to reliably separate the two, and the slope can be easily separated without using a soccer ball. The separating claw and its operating mechanism are constructed so that they can be moved integrally, so that binding fittings of various sizes can be easily used. It is something.

Embodiments of the present invention will be described in detail with reference to the accompanying drawings: 1.
Reference numeral 1 denotes a mounting rod, which is attached in parallel to a rectangular shaft 4 horizontally suspended on the body 3 via a slide boss 2 fixed to the lower surface of the mounting rod, and whose tip end is placed close to the folding knife 5 of the binding machine. The lower end side is set higher at an angle of about 15 degrees.

6 indicates a fixing bolt between the slide boss 2 and the rectangular shaft 4.

The mounting rods 1, 1 each have guide plates 7, 7 fixed to their inwardly facing surfaces, and a recess 8 into which a follower (to be described later) is inserted is formed at a required position near the tip of the outer surface. A swing hole 9 communicating with the guide plates 7, 7 is bored in the center.

Reference numeral 10 indicates a main rail, and reference numeral 11 indicates a brake rail, both of which are attached to the inside of the guide plates 7, 7 via required collars 12. Approximately 1 parallel to the guide plate when viewed from Figure 1
The tip is rotatably fixed to the guide plate 7 by a pin 13, and the distal end is supported by an adjustment screw 14 provided on the guide plate 7, and the angle of inclination is adjusted by rotating the adjustment screw 14. It is adjustable.

The sub-rail 11 is attached from the tip of the main rail 10 toward the folding knife 5 of the binding machine at a steeper angle than the main rail 10.

Reference numeral 15 denotes a rotating shaft, which is located below the tip of the main rail 10 at right angles thereto, and is connected to a motor 16 installed inside the fuselage 3.
and is connected via a chain, belt, or other arbitrary transmission mechanism 17.

Reference numeral 18 denotes a cylindrical cam, which has a groove 19 having a sine curve displacement characteristic in its circumferential surface as shown in FIG. 4, and is connected to the rotating shaft 15 by a key 20.

Here, the key 20 is set in a considerably long range along the rotating shaft 15, and the interval between the cylindrical cams 18 can be arbitrarily adjusted within this range.

2L22 is a follower of the cylindrical cam 18, which forms a semicircular recess 23 sufficient to fit into the circumferential surface of the cylindrical cam 18 from one side, and a projection 24 sufficient to engage with the groove 19 from the bottom thereof. is provided protrudingly, and is attached to the cylindrical cam 18 with both followers 2L22 facing each other.

Reference numerals 25 and 26 denote holders for the driven elements, and the holder 25, which has an L-shaped side surface, has a substrate fixed to the lower surface of the mounting base rod, and vertical pieces 25a are set on the front and rear surfaces of the driven elements 21 and 22. A piece 25 that accommodates a holder 26 whose side surface is U-shaped.
Cover the bottom and side surfaces between portions a and attach to the holder 25 with screws.

Reference numeral 27 denotes a metal fitting holding plate, which is fixed to the upper surface of the follower 21 provided on the front side of the rotating shaft, and has a through hole whose tip 27a communicates with the mounting rod 1 and the guide plate 7 as the follower 21 moves back and forth. Protrude or retract inward from 9.

Reference numeral 28 denotes a separation needle, which is formed into a wedge shape that gradually becomes thinner toward the tip, and is provided with a follower 22 on the rear side of the rotating shaft 15.
The tip 28a and the metal fitting holding plate 27 alternately protrude from the through hole 9 as the metal fitting presser plate 27 moves back and forth.

To explain how to use the present device configured as above, first loosen the fixing bolt 6, set the distance between the guide plates 7, 7 to the required length of the binding metal fittings, and insert the multiple binding metal fittings. Stack them on the main rail 10 with the groove facing forward.

Since the main rail 10 is inclined, the binding metal fittings slide down together due to their own weight, and the leading binding metal fitting is retained by the metal fitting holding plate 27.

Next, when the motor 16 is rotated to drive the rotating shaft 15,
As the cylindrical cam 18 rotates, the follower 21, that is, the metal fitting holding plate 2γ moves backward, and the follower 22, that is, the separation needle 28 protrudes.

The separation needle 28 connects the first binding metal fitting A1 and the second binding metal fitting A1.
However, since the separation needle 28 is formed in the model, the second and subsequent binding fittings are pushed back by the slope of the separation needle 28, and the first binding fitting is completely inserted. The paper is separated and slid down the sub-rail 11 to be supplied to the binding machine F.

When the cylindrical cam 18 further rotates, the separation needles 28 are sequentially retracted and the fitting presser plate 27 is protruded, and by repeating the above steps, the binding fittings on the rail are fed one by one to the binding machine.

Next, when using binding fittings of different lengths, the fixing bolt 6 is loosened and the entire mounting rod 1 and its attachments are moved along the rectangular shaft 4 to adjust the spacing.

Also, when using binding fittings with different widths, adjust the adjustment screw 1.
4 to adjust the angle of the main rail 10 so that the fitting presser plate 27 and the separation needle 28 accurately abut the insertion groove C of the binding fitting.

The binding fitting separation and supply device of the present invention is configured so that the separating needle 28, which serves as a model, is inserted between the first binding fitting and the second binding fitting to separate the two, so that it is possible to reliably feed one binding fitting. can be supplied to the binding machine, and it can be manufactured at low cost since it does not require an expensive air system or the like as in the past.

Further, since a cylindrical cam is used as a mechanism for alternately protruding the metal fitting holding plate 27 and the separation needle 28, not only the operation is reliable but also the driving device can be extremely simple.

Furthermore, since all the necessary accessories are integrally attached to the mounting rod 1, the spacing can be easily adjusted by simply loosening the fixing bolt 6, and it is easy to switch to various binding fittings with different lengths.

Furthermore, since the main rail is provided with an adjustment screw so that the angle can be freely adjusted, it has the advantage that it can be applied to binding fittings of different widths.
