DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention uses aluminum cans, iron cans, etc.
The present invention relates to a can lid feeding device that can be used for a can seamer of a can of canned juice.

(Prior Art) Conventionally, various types of can lid feeders for can seamers have been proposed, and an example thereof will be described with reference to FIG. It is conveyed by the conveyor 3 and sent to the seaming turret 4. 5 is a can lid supply turret arranged in contact with the seaming turret 4, and the seaming turret 4 is provided on the outer periphery.
Guide groove 5a corresponding to the guide groove 4a of the can 2 provided on the outer periphery of the
The can lid 7 is dropped from the upper can lid feeding mechanism 6 in the guide groove 5a, and the dropped lid 7 is conveyed by the can feeding conveyor 3 and fed to the seaming turret 4. Is supplied onto the can 2. Thereafter, a can 2 and a lid 7 sent to the seaming turret 4 are wound and closed by a seaming roll (not shown) arranged around the seaming turret 4, and thus the completed canned can 2 ′ has an outlet turret 8. After that, it is sent to the next process.

(Problems to be Solved by the Invention) The production amount of canned cans such as beer cans and juice cans is increasing year by year, and the can sizes tend to be more and more diverse. Therefore, even in the conventional can seamer, the size of the can lid is often changed along with the change of the can size. That is, since the can lid diameter changes with the change of the can diameter, it is necessary to switch to a lid supply turret having a guide groove diameter suitable for this and also to change the height position of the lid supply turret by changing the can height. However, many bolts must be removed for these changes and replacements.
It takes a lot of time because of work such as mounting, and it is impossible to switch or change in a short time. Therefore, the conventional apparatus has a problem in that it cannot meet the demand for a shorter switching time due to an increase in the frequency of changing the can size.

Further, since the can lid feeding device including the lid feeding turret 5 and the can lid feeding mechanism 6 shown in FIG. 8 is installed at the inlet of the can seamer, it is more troublesome to remove and install the bolts and the like. In addition to the above drawbacks, even if an attempt is made to make the can lid feeder have an external setup structure, it is necessary to align the installation location with the seaming turret 4 with high accuracy, which makes it difficult to have the external setup structure. .

The present invention aims to provide a can lid feeder which can be set up externally by lowering the required alignment accuracy of the can and the can lid feed turret to a level that can be practically achieved by setting the installation location on the can feed conveyor. .

(Means for Solving Problems) Therefore, in the present invention, the liquid is supplied in the can seamer in which the can supplied with the liquid by the filler is sent to the seaming turret of the seamer through the can supply conveyor. A plurality of can lid supply mechanisms for supplying the can lids of the cans, which are switchable, and which are arranged in the can feed conveyor between the filler and seamer. Then, this is a means for solving the problem.

(Operation) Of the multiple can lid supply mechanisms, other than the one that is operating, replace the can lid member that matches the can size that will be changed in the next process, and set it to the required height. For example, an extra time is set during the operation of the one of the above-mentioned mechanisms to perform the external setup. Then, when it is necessary to change the can lid diameter and the can height due to the change of the can type, the other mechanism is immediately switched to the operating position, and the operation according to the can size of the next step is started in a short time.

(Embodiment) The present invention will be described below with reference to embodiments of the drawings. Figs. 1 to 7 show an embodiment of the present invention, 1 is a filler, 2 is a can, 3 is a can supply conveyor, and 4 is a seamer. Seaming turret, 8 is an exit turret, which are the same as the conventional one shown in FIG. Reference numeral 10 denotes a can lid feeder which is the main point of the present invention, and as shown in FIGS. 1 and 3, two can body guide turrets 11 and 11a are provided and can be used by alternately switching. Yes, the turret 11a when not in use is set up with a can lid for a can size to be used next. Also, 12 in Fig. 1
Is the entrance guide.

Next, the can lid feeder 10 will be described in detail with reference to FIGS. Here, the can body guide turrets 11 and 11a are connected to the drive gear 14

It is adapted to be driven and rotated by a drive gear 14 via 20 '. The 180 ° turning operation of the bracket 17 is performed manually. It can also be automated using a separately installed power source. Reference numeral 18 is a shaft for synchronizing with the rotation of the seamer 9 which rotates in the arrow direction by the rotation of the gear 17. Further, the gear 19 is a cylindrical body having a drop hole 21 of the can lid 7 via an intermediate gear 20 as shown in FIGS. 4 and 5.
A gear 23 that rotates around 22 is driven. The gear 23 meshes with a gear 26 fixed to a shaft 25 which is the center of rotation of the rocking gear box 24, and a gear 27 is fixed on the coaxial 25, and the gear 27 has a rocking gear box. A gear 29 fixed on a shaft 28 rotatably supported by 24 is meshed, and a can lid separator 30 is fixed to the lower end of the coaxial 28. The can lid separator 30 has a function of separating the can lids 7 that have fallen from the drop holes 21 and are stacked one by one and supply the can lids 7 to the grooves 32, 32 of the rail 31. 33
Is a pusher mounted between the guide grooves 11 ′ and 11 ′ on the can body guide turret 11 for removing the can lid 7 supplied to the rail 31,
According to the rotation of the can body guide turret 11 along the rail grooves 32, 32, the can body guide turret 11 is held and transferred immediately above the guide groove 11 '. The position where the can lid 7 is conveyed on the can supply conveyor 3 and reaches the can 2 engaged with the can body guide turret 11 is:
Since it is the end of the grooves 32, 32, the can lid 7 comes off the grooves 32, 32 and drops onto the can 2 directly below, and the can 2 is sent to the seamer 9 with the lid 7 placed on the can mouth. Then, the tightening process is performed.
The grooves 32, 32 are inclined downward toward the terminal end so that the drop distance when the can lid falls onto the can is reduced so that the can lid can be accurately dropped onto the can. There is.

The operation will be described below. The can 2 filled with the liquid by the filler 1 is conveyed by the can supply conveyor 3 toward the can lid supply device 10.

Also, by the drive gear 14 rotating via the drive shaft,
The gear 19 rotates via the intermediate gear 20 ', and the can body guide turret 11 rotates via the shaft 16. In this case, the can barrel guide turret 11a during the external setup is prevented from rotating by switching the clutch or the like. Since the gear 23 meshes with the gear 20, the rotation of the gear 20 causes the gear 2 to rotate.

Next, the external setup will be described. Due to the diversification of can sizes such as canned beer and canned juice in recent years, it has been demanded to change the can lid in a short time according to the can size. For this reason, the can body guide turret must be replaced, or even the turret. The height of must be changed. According to the embodiment of FIGS. 1 to 3 of the present invention, the can barrel guide turret 11a which is not in operation in FIG. 1 is guided to the can lid member which is adapted to the can size to be changed next. Use the idle time while the turret 11 is operating to replace it and set it up outside.
