Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a can lid transferring jig used for transferring a can lid which is tightly wound around a can body of a can of juice or the like.

[0002]

2. Description of the Related Art A conventional can lid transfer device of this type is shown in FIG. A predetermined number (for example, 250) of disc-shaped can lids are stacked and packaged and then received at a canning factory, and the packaging is unpacked by an unpacking machine (unwrapper) 1. After a while
A can lid row 7 composed of a predetermined number of can lids is successively extruded by the air cylinder 2 and supplied to a winding machine (seamer) 6 through a can lid transfer path 5 composed of a conveyor 3, a chute 4 and the like. Each can lid 8 is successively wound and fixed to the top opening of the can body, which is pre-filled with juice, retort food, carbonated alcoholic beverage and the like.

When the can lid 8 is sent out from the can lid transfer path 5 and emptied when the canning factory is out of operation, when the type of canned goods is switched, etc., the can lid 8 at the tail of the can lid row 7 falls over. In order to prevent this, a can lid transfer jig is arranged at the rear end of the can lid row 7. Further, when the can lid row 7 is sent into the empty can lid transfer path 5 at the time of operation start, the can lid row 7 at the head of the can lid row 7 is prevented from tipping over in order to prevent the can lid row 7 from tipping over. A lid transfer jig is arranged.

As shown in FIG. 5, a conventional can lid transfer jig 10 includes a large number of can lids 11 (200 to 200) of the same kind as the can lid 8 to be transferred.
(350 sheets) were laminated, and both ends of the wire 13 penetrating the hole 12 formed in the center thereof were joined to the abutting member 14.

[0005]

The conventional jig 10 is a bent portion of the conveyor 3, and as shown in FIG. 6, the can lid 11 is biased or the postures thereof are different, so that the can lid 11 is guided. It is said that the jig 10 is caught on the jig 15, the friction between the can lid 11 and the guide 15 is increased, and the jig 10 is stopped at the bent portion of the conveyor 3, and as a result, the can lid 8 at the rear of the can lid row 7 falls down. Trouble was frequent.

Further, since the jig 10 descends faster than the can lid row 7 on the chute 4, the can lid 8 comes apart and falls.

[0007]

SUMMARY OF THE INVENTION The present invention has been invented to solve the above-mentioned problems, and its gist is to provide a disk-shaped can lid which is fastened to a can body for canning. When the cans are sequentially transferred from the unpacking machine to the wrapping machine via the can lid transfer path, they are placed at the beginning or the end of the can lid row consisting of a large number of can lids unpacked by the above unpacking machine to prevent the can lids from falling. In the can lid transfer jig described above, abutting members that come into contact with the can lid are fixed to both ends of a flexible cylinder that has a substantially same diameter as the can lid and has a predetermined length and is freely bendable. There is a jig for can lid transfer.

Another feature is that the flexible cylinder is constituted by a coil spring having a length at least twice the diameter of the can lid.

Still another feature is that the abutting members at both ends are connected to each other by a flexible strip such as a string, a wire or a chain.

Still another feature is that a recess is provided on the outer surface of the contact member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A can lid transfer jig according to an embodiment of the present invention is shown in FIG. This jig 20 has substantially the same diameter as the can lid 8 to be transferred and has a predetermined length, and abutting members 22 for abutting the can lid 8 are fixed to both ends of a flexible tube 21 which can be freely bent. It is composed by.

For canning with a capacity of 250 ml, a flexible tube
21 is a coil spring made by winding a spring steel with a wire diameter of 2.5 mm in a coil shape with an outer diameter of 55 mm and winding it around each other without gaps. By fixing, the total length of jig 10 is 870mm
It has been.

A recess 23 is formed in the outer surface of the contact member 22, that is, in the center of the surface contacting the can lid 8, into which the tip of the guide rod is depressed. The pair of contact members 22 are connected to each other by a plastic chain 24 that penetrates the inside of the coil spring, as shown in FIG. 1 (B).

For canning with a capacity of 350 ml, a flexible tube
21 is a coil spring made by winding a spring steel with a wire diameter of 3.0 mm in a coil shape with an outer diameter of 60 mm and winding it around each other without gaps. By fixing, the total length of the jig is 630m
m. In this case, since the wire diameter of the spring steel is large, the chain 24 can be omitted. If the diameter of the can lid changes in accordance with the change in the capacity of the canned goods, the outer diameter and the total length of the jig 20 are appropriately changed.

When the can lid transfer path 5 is emptied, a jig 20 is disposed in the can lid transfer path 5 so as to be located at the rear end of the can lid row 7, and the tip of the jig 20 is touched. The contact plate 22 contacts the rear surface of the last can lid 8 of the can lid row 7. At the start of operation, the jig 20 is arranged in the can lid transfer path 5 so as to be located at the head of the can lid row 7, and the contact plate 22 at the rear end of the jig 20 is located at the head of the can lid row 7. It contacts the front surface of the lid 8.

The jig 20 moves along with the movement of the can lid row 7. When the jig 20 passes through the bent portion of the conveyor 3, the flexible tube 21 is guided by the guide 15 as shown in FIG. Since the jig 20 bends freely along the guide 15, the jig 20 will not be caught by the guide 15 or stopped due to increased friction.

When the jig 20 reaches the entrance of the chute 4, as shown in FIG. 3, the tip of the guide rod 16 is placed in the recess 23 provided at the center of the contact plate 22 at the tip of the jig 20. If the guide rod 16 is fitted and moved at a speed substantially the same as the moving speed of the can lid row 7, the can lid 8 can be prevented from being scattered by the chute 4 and scattered.

In the above embodiment, the flexible cylinder 21 is composed of a coil spring, but it may be composed of a rubber tube, a bellows or the like.

[0019]

According to the jig for transferring a can lid of the present invention, the abutting member for abutting the can lid on both ends of a flexible cylinder having substantially the same diameter as the can lid and having a predetermined length and freely bendable. Since the fixing is performed, the flexible tube of the jig is also freely bent along the guide even in the bent portion of the can lid transfer path, so that the jig can smoothly pass through the bent portion.

If the flexible cylinder is composed of a coil spring having a length at least twice the diameter of the can lid,
The coil spring bends smoothly and is restored to its old shape by its elasticity, and the jig is stably seated in the transfer path, so that the bent portion of the transfer path can be moved more smoothly.

If the abutting members at both ends are connected to each other by a flexible strip such as a string, a wire, or a chain, the coil springs are extended even if the wire diameter of the coil springs is small, and the wire springs are mutually connected. It is possible to prevent the gap from becoming too large.

If a recess is provided on the outer surface of the abutment member, the guide rod will not be disengaged from the jig by inserting the tip of the guide rod into the recess at the entrance of the chute. Since it can be smoothly introduced into the chute by guiding with, the can lid can be prevented from being scattered and scattered by the chute.
