CONSTITUTION:A separation mechanism 12 is composed of a pair of right and left cams 20a-20d, each of which has a different phase, and of arms 28a-28d provided with engaging pin 32a-32d. A transfer mechanism 14 is composed of a crank shaft 20, adsorption arm 50 provided with a magnet 48, a connecting member 52, and an operation rod 55. A transfer section 16 is composed of an eccentric cam 24, an operating rod 62, and a receptor 58. And the operation of each of these two mechanism (12 and 14) and one section (16) is allowed to be well timed because a drive shaft 18 is common to cams 20a-20d, the crank shaft 22, and the eccentric cam 24. Accordingly, the lowermost clamp fitting A1 is separated (12) from the second one A2 by the drive shaft 18, is absorbed for transfer, and is finally forwarded. This configuration enables the separation and feed operations to be smoothly and positively effected.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a fastener supply device, and more specifically, it relates to a fastener supply device for winding one end of collated calendar paper sheets (hereinafter referred to as a calendar booklet). This invention relates to a device for supplying fasteners in a seaming machine that tightens to produce booklet-like calendars.

[Prior Art] In general, a booklet-like calendar is produced by tightening a fastener on one end of a calendar booklet made by collating a plurality of printed calendar sheets using a tightening machine.

By the way, as a means for supplying fasteners in such a seaming machine, for example, a large number of fasteners (lugs) are stacked and waiting on an inclined chute, and the fasteners are placed at positions corresponding to both ends of the fasteners on this inclined chute. A device in which stoppers for a pair of left and right are arranged so that the upper and lower pairs move back and forth alternately and synchronously on both the left and right sides, and the stoppers are moved back and forth alternately to supply the fasteners to one piece (Japanese Patent Publication No. 54-39772) Publication No. 2) has been proposed for the convenience of consumers.

[Problem that the invention seeks to solve]

However, in this type of fastener supply device, a pair of left and right stoppers are moved back and forth to alternately insert and remove the fasteners into the hooks of the fasteners to feed a single fastener, so the stoppers overlap each other. There is a problem in that the fastener is easily worn out due to friction when it is laterally inserted or pulled out between the end faces of the fastener, and lacks durability. In addition, when this stopper wears out, the wear rate of the left and right stoppers is not necessarily uniform, so there may be a timing difference in the movement of the left and right stoppers when releasing the fastener. Separation, in other words, not only will the feeding work not be carried out smoothly, but there is also a risk that the fasteners will be fed to the seaming position in an inclined state, which will require a lot of work interruption time to correct this, and the seaming process will be delayed. There were some points that needed improvement, such as reduced work efficiency.

[Means for solving problems]

Therefore, in order to solve the above-mentioned problems, this invention
A separation mechanism that sequentially separates the lowest fasteners from a large number of fasteners stacked on the inclined chute, a transfer mechanism that transfers the separated fasteners to the lower part of the inclined chute, and a receiving mechanism that receives the transferred fasteners. The fasteners can be smoothly tightened by providing a feeding mechanism that once holds the metal horizontally and then feeds it to the tightening position, and a timing mechanism that interlocks the separation mechanism, the transfer mechanism, and the feeding mechanism at a predetermined timing. The aim is to achieve reliable and reliable separation or supply and to improve the durability of the device itself.

[For production]

In the fastener supply device according to the present invention, a separation mechanism sequentially separates a large number of fasteners stacked on an inclined chute, and a transfer mechanism transports the separated fasteners to a lower part of the inclined chute. After being held horizontally by the feeding mechanism, it is fed to the seaming position.

The arm member 50 is connected to the crankshaft 22 of the drive shaft 18 via a connecting member 52 fixed to the shaft 46 and an operating rod 54, and is configured to swing about the shaft 46 as a fulcrum.

Further, the feeding mechanism 16 has one end connected to the inclined chute 10.
It consists of a pair of plate-like members 60a and 6Qb which are pivotally supported via a shaft 56 at the lower side of the board and have fastener receiving parts 58a and 58b formed at the other end thereof, and these plate-like members 60a
, 60b is configured to be tiltable about the shaft 56 by engaging the end of the operating rod 62 fixed to the pivot portion with the eccentric cam member 24 of the drive shaft 18 via the roller member 64. In this case, the operating rod 62 is elastically held against the eccentric cam member 24 by a tension coil spring 65 disposed on the side of the inclined chute 10.

In addition, in the attached drawings, reference numerals 66a and 66b are
The separated position of the fastener and the separated fastener are the plate member 60a.

Next, the operation of supplying fasteners in the fastener supplying device according to the present invention configured as described above will be explained. In this case, in order to simplify the explanation, the reference numerals shown in FIG. 2 will be used as much as possible for the reference numerals of the same members.

First, when a large number of fasteners A with their hooks facing upward are stacked on the inclined chute 10, the locking pin 32b engages with the upper side of the fastener A located at the lowest stage. Furthermore, the locking pin 34b is located slightly above the upper end of the fastener because the roller member 30c of the arm member 28c engages with the protrusion 21C of the cam member 20c.

Therefore, all the fasteners on the inclined chute 10 are connected to the locking pin 32b.
(Fig. 4a). In addition,
In this state, the suction arm member 50 of the transfer mechanism 14 is tilted upward about the shaft 46 and held at a position away from the separation position of the fastener (not shown), and the plate-like member 50 of the feeding mechanism 16 is Part 60b is waiting in the receiving position for the fastener.

When the drive shaft 18 is rotated by the drive motor M in this state, the protrusion 21c of the cam member 20c and the arm member 2
8c is disengaged from the roller member 30c, the locking pin 34b of this arm member 28c comes into contact with the side edge of the hook portion of the fastener A2 located at the next stage after the fastener A located at the lowest stage. are engaged (Fig. 4b).

Next, this time, the projection 21d of the cam member 20d and the roller member 30d of the arm member 28d engage with each other, and the locking pin 32b is released from the lowermost fastener AI. , is separated from the group of fasteners A stacked above it, and this fastener A1 is attracted to the magnet 48 of the attracting arm member 50 that approaches by operating the operating rod 54 attached to the eccentric wheel 23 and the connecting member 52. (Fig. 4C). In this state, a locking pin 34b is attached to the hook side edge of the fastener A2 located next to the fastener A1.

The locking pin 34b that engages with the fastener A2 is the cam member 20C.
The locking pin 32b moves upward due to the engagement between the projection 21c of the cam member 20d and the roller member 30C, and the locking pin 32b further approaches the upper surface of the fastener A2 due to the release of the engagement between the projection 21d of the cam member 20d and the roller member 30d. It engages in figure 4f.

When the fastener A is sent to the tightening position, the plate member 60b is moved by the roller member 64 and the operating rod 6 by the eccentric cam member 24.
2 returns to the original position, the engagement between the fastener A2 and the locking pin 34b is also released, and the next feeding operation, that is, the feeding operation of the fastener A2 is started (FIG. 4f).
