Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for storing slide fasteners that are sorted into a tray in the process of packaging manufactured slide fasteners. To hold a tray immovably while sequentially inserting slide fasteners into the tray, and to store the tray in an orderly manner without changing the insertion position.

As is well known, when finished slide fasteners are packaged into bags or boxes, a predetermined number of slide fasteners are arranged in an orderly manner before packaging. The slide fasteners that are sent to the tray at regular intervals are transported and inserted into the tray by a conveying device. However, if the slide fasteners are always inserted into the tray at the same point, they will pile up in the tray, so the tray must be inserted little by little. Either the tray is moved to one side, or the tray is left fixed and the insertion position is sequentially displaced. If this were to be automated, a mechanism would be required to move the tray and the insertion position, resulting in an extremely complicated structure.

This invention was developed in order to solve the above-mentioned drawbacks.The slide fastener sent by a conveyor is placed on one side and placed on the side, and the tray is inserted diagonally into a certain position, and immediately before the insertion. The present invention is characterized in that the slide fasteners are stored in the tray by pressing and moving the slide fasteners already stored in an inclined direction and inserting them into the space created by the pressing.

Hereinafter, an embodiment of the method according to the present invention will be described in detail. As shown in FIG. It is received in pallet 2, but when receiving it fastener F
receives the tray 1 in parallel with one side of the tray 1, and places the pallet 2 in a tilted state with the tip thereof raised.At the same time as receiving the fastener F, the fastener F is transferred to the base of the pallet 2. Next, the pallet 2 is tilted and its tip is inserted into the tray 1, and the first fastener F already stored in the tray 1 is pushed in the direction of tilting on the back of the pallet 2, and at this time, the top of the pallet 2 is The fastener F has slipped to the tip, and there, the pallet 2 is pulled out from inside the tray 1 while the pallet 2 remains tilted, and the fastener F received on the pallet 2 is stored in the tray 1.

Next, an embodiment of the apparatus according to the present invention will be described. As shown in FIG. They are arranged perpendicular to the direction and placed at a predetermined interval. In addition, the fastener F sent by the conveyor 3 is attached to the slider S as shown in FIG.
It is very receding and some parts are open.
Either it is completely closed normally while being sent on the conveyor 3, or as shown in the figure, when it falls from the conveyor 3, it is caught by a pair of grippers 4, 4,
There is a system in which both grippers 4, 4 are moved left and right to fully close them, and then both grippers 4, 4 are opened and tilted to drop the fastener F downward.

Therefore, a separate conveyor 5 is installed below the end of the conveyor 3 so as to feed in the same direction as the upper conveyor 3, and a large number of trays 1 are placed on the lower conveyor 5 at equal intervals. It is configured to be installed at each location and transferred intermittently.

A support body 6 is provided between the upper conveyor 3 and the lower conveyor 5, and is supported on an arm 8 that protrudes from the frame 7 and swings in the same direction as the conveyance direction of the lower conveyor 5. The pallet 2 is pivotally supported on the support 6 so as to be able to swing up and down, and a piston rod 11 of a cylinder 10 driven by air pressure or the like is fixed to a bending piece 9 that stands up from the pivot portion of the pallet 2. The top end is kept in a tilted state so that the pallet 2 can receive the fastener F falling from the upper conveyor 3 or gripper 4, and when the pallet 2 is tilted downward, the top end The supporting position of the support body 6 and the length of the pallet 2 are set in relation to the position of the tray 1 to be stored and the upper conveyor 3 so that the tray 1 is inserted into the tray 1 in an inclined state. . The arm 8 also has a piston rod 1 of a cylinder 12 which is driven by air pressure or the like.
3 are connected, and when the pallet 2 is released from the above-mentioned state in which it is thrust into the tray 1, the pallet 2 is not moved backwards,
The structure is such that the support body 6 is swung while the pallet 2 remains tilted, and the pallet 2 is pulled out and released. Therefore, the support body 6 may be supported so as to move obliquely upward.

The above-mentioned device is automated, and a counting device 14 is provided above the upper conveyor 3, and the signal generated by the counting device 14 when the number is full is used to drive the lower conveyor 3. tray 2
to the insertion position. Further, a sensor 15 for sensing the fastener F falling from the conveyor 3 is provided adjacent to the counting device 14, and the gripper 4 is actuated by the output signal of the sensor 15. Furthermore, although not shown, the gripper 4 tilts and the fastener F
The piston rod 11 of the cylinder 10 of the pallet 2 is
drive forward. Also, after storing the fastener F, remove the piston rod 1 of the cylinder 12 of the arm 8.
3, and after a predetermined time, both cylinders 10 and 1 are moved forward.
2 is controlled by a timer so that it moves backwards.

In addition, in the above structure, the lower conveyor 5
It is also possible to arrange the conveyor 3 perpendicularly to the upper conveyor 3.

This invention has the above structure, and as shown in FIG. 2, the fastener F that has fallen from the upper conveyor 3 is received between the grippers 4, and after the fastener F is fully closed, the pallet 2 is removed as shown in FIG. Since the pallet 2 is tilted and supported with its tip elevated, the fastener F slides down into the support part of the pallet 2. Then, by tilting pallet 2, tray 1 can be removed by pallet 2.
At the same time, the fasteners F on the pallet 2 slide down and are inserted into the tray 1. Next, when the arm 8 is driven, the support body 6 rises in an arc in the same direction as the feeding direction of the lower conveyor 5, so that the pallet 2 escapes from the tray 1 while remaining tilted.
The fastener F on top is stored in the tray 1. Thereafter, the support body 6 and the pallet 2 move back and return to their original state, and the above-described operation is repeated again. In this way, a predetermined number of fasteners F are placed in the tray 1.
After storing, the lower conveyor 5 is sent to transport the next empty tray 1 to the storage position.

Note that the first fastener F inserted into tray 1 will be horizontal to the bottom, but the fastener F inserted next
As shown in the figure, the fasteners F are arranged horizontally in an inclined state, and finally the fasteners F, which are lying down at the beginning, are brought up by the guidance of the side wall of the tray 1.

As described above, in the method according to the present invention, the fastener is inserted from above the middle part of the tray toward the side corner while lying down, and immediately before the insertion operation, the fastener already stored in the tray is inserted into the tray. Since the tray is stored by being pressed toward the opposite corner, there is no need to move the tray during storage, and at the same time, there is no need to change the insertion position relative to the tray, making the operation for storage extremely easy. In addition, since the fasteners are stored in a horizontally overlapping manner within the tray, they are surely stored in an orderly manner without being disturbed during storage.

Furthermore, since the device according to the present invention is composed of a conveyor for transporting trays and a pallet installed on the conveyor, it is possible to achieve the above-mentioned storage method with an extremely simple structure.
Even when automating this device, since the movements of each member are simple, it is easy to apply power and control them. In addition, since the pallet is pivotally supported so that it can swing, the fasteners can be inserted and pushed in at the same time.Furthermore, when the pallet is removed, the pallet is pulled out with the pallet tilted, so the inserted fasteners can be removed easily. are naturally removed from the pallet and stored in the tray.
A predetermined number of items are stored in an orderly manner with nothing standing out.
