This invention relates to a can lid supply device that can be used as a can seamer for cans filled with juice, etc.

(Prior Art) Various types of can lid supply devices for can seamers have been proposed in the past, and one example will be explained with reference to FIG. It is conveyed by a conveyor 3 and sent to a seaming turret 4. 5 is a can lid supply turret arranged in contact with the seaming coolet 4, and the seaming turret 4 is arranged on the outer periphery
A guide groove 5a corresponding to the guide groove 4a of the can 2 provided on the outer periphery of the can is formed, and a can lid 7 is dropped into the guide groove 5a from an upper can lid supply mechanism 6, and the dropped lid is 7 is conveyed by the can supply conveyor 3 to the seaming turret 4
It is supplied on the chemical 2 which is about to be supplied. Thereafter, the can 2 and the lid 7 fed into the seaming turret 4 are seamed by seaming rolls (not shown) disposed around the seaming turret 4, and the can 2' thus completed passes through the exit turret 8. After that, it is sent to the next process.

(Problem to be solved by the invention) The production volume of cans such as beer cans and juice cans is increasing year by year, and can sizes are also becoming more diverse. The size of the can lid is often changed accordingly.In other words, changing the can diameter also changes the can lid diameter, so it is necessary to switch to a lid supply turret with a guide groove diameter that matches this, or to change the can height. It was also necessary to change the height position of the lid supply turret, but these changes and replacements required the removal and installation of many bolts, which took a lot of time. Changes were not possible.Therefore, with conventional equipment,
There have been problems such as the inability to meet the demand for shorter changeover times as the frequency of can size changes increases.

Furthermore, since the can lid supply device consisting of the lid supply turret 5, can lid supply mechanism 6, etc. shown in Fig. 8 is installed at the entrance of the can seamer, it is troublesome and time-consuming to remove and install bolts, etc. In addition to these drawbacks, even if this can lid supply device were to have an external setup structure, the installation location had to be aligned with the seaming turret 4 with high precision, making it difficult to use an external setup structure. .

The present invention aims to provide a can lid supply device that is installed in the middle of a can supply conveyor, reduces the required positioning accuracy of cans and can lid supply turrets to a practically achievable level, and enables external setup. be.

(Means for Solving the Problems) Therefore, the present invention provides a can seamer in which cans supplied with liquid by a filler are sent to a seaming turret of the seamer via a can supply conveyor. A device having a plurality of can lid supply mechanisms for supplying can lids to cans, making them switchable, and disposing the supply mechanism in the middle of the can supply conveyor between the filler and the seamer. This is a means to solve problems.

(Function) Among the multiple can lid supply mechanisms, except for one that is in operation, the other mechanisms are replaced with can lid members that match the can size that will be changed in the next process, and set to the required height. Use the extra time while one of the mechanisms is operating to make external setups. Next, when it becomes necessary to change the can lid diameter and can height due to a change in the can lid, the other mechanism is immediately switched to the operating position and the operation according to the can size of the next process is started in a short time.

(Embodiment) The present invention will be described below with reference to the embodiments shown in the drawings. FIGS. 1 to 7 show embodiments of the present invention, where 1 is a filler, 2 is a can, 3 is a can supply conveyor, and 4 is a seamer 9. The seaming turret, 8, is the same as the conventional one shown in FIG. Reference numeral 10 denotes a can lid supplying device which is the main point of the present invention, and as shown in FIGS. 1 and 3, a can body guide turret is connected to 11. There are two turrets, lla and turret lla, which can be used by switching alternately.When not in use, the turret lla is used to set a can lid for the next can size to be used. .

Further, 12 in FIG. 1 is an entrance guide.

Next, the can lid supply device 10 will be explained in detail with reference to FIGS. 1 to 7. Here, the can body guide turret 11° 11a can rotate 180° around the drive shaft 15 of the drive gear 14,
It is rotatably attached to the lower surface of a bracket 17, which can be fixed in a rotating position by a stopper or the like (not shown), with a rotating shaft 16. A gear 19 is fixed to the rotating shaft 16, and the gear 19 is driven and rotated by the drive gear 14 via an intermediate gear 20'. Note that this 180° turning operation of the bracket 17 is performed manually. It can also be automated using separately installed power. Reference numeral 18 is a shaft for synchronizing the rotation of the seamer 9, which rotates in the direction of the arrow due to the rotation of the gear 17.

The gear 19 also drives a gear 23 which rotates around a cylinder 22 having a drop hole 21 for the can lid 7 through an intermediate gear 20 as shown in FIGS. 4 and 5. ing.

The gear 23 meshes with a gear 26 fixed to a shaft 25, which is the center of rotation of the swing gear box 24, and
A gear 27 is fixed on the top of the gear 27, and a gear 29 fixed on a shaft 28 rotatably supported by the rocking gear box 24 meshes with the gear 27. A lid separator 30 is fixed. The can lid separator 30 comes from the drop hole 21 and is stacked with can lids 7.
The function is to separate the sheets one by one and supply them to the grooves 32 and 32 of the rail 31.

33 are guide grooves 11', 11 on the can body guide turret 11.
The can M7 supplied to the rail 31 is held and transferred directly above the guide groove 11' according to the rotation of the can body guide turret 11 along the grooves 32 and 32 of the rail with a button installed between the two. 4゜And this can lid 7 is connected to the can supply conveyor 3.
The can 2 is conveyed above and engaged with the can body guide turret 11
Since the position reached at the top is the end of the grooves 32 and 32, the can lid 7 comes off the grooves 32 and 32 and falls onto the can 2 directly below, and the can 2 places the lid 7 on the can opening. In this state, it is sent to the seamer 9 where it is seamed and tightened. Note that the groove 32°3
2 is inclined downward toward the terminal end, so that when the can lid falls onto the shelf, the falling distance is reduced, so that the can lid falls accurately onto the shelf.

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

Further, as the drive gear 14 rotates via the drive shaft, the gear 19 rotates via the intermediate gear 20', and further the shaft 1
6 rotates the can body guide turret 11. In addition,
In this case, the can body guide turret lla during external setup is prevented from rotating by switching a clutch or the like. Also, since the gear 23 meshes with the gear 20, the gear 20
The rotation of gears 23.26 rotates, and the rotation of gears 27.29 through shaft 25 rotates shaft 2g,
Rotate the can lid separator 30.

The cans M7 are supplied from the hopper 34 and are supplied to the drop hole 21 of the cylindrical body 22 in a stacked manner. And the bottom can M
7 is taken out by the rotation of the can lid separator 30 and fed into the grooves 32 and 32 of the rail 31. Groove 32
．． The can lid 7 that has entered the can lid 32 is pushed by a button 33 attached to the can body guide turret 11 below it, and is transferred while being held at a position directly above the guide '(R11') of the can body guide turret 11. As described above, the cans 2 are sent by the can supply conveyor 3 and fall from directly above the can 2 at the position where it engages with the guide groove 11' of the can body guide turret 11 toward the mouth, and at the position where the grooves 32 and 32 disappear. The can with the can M7 placed thereon is further conveyed by the can supply conveyor 3 toward the seamer 9, supplied to the seaming turret 4, and seamed by a seaming roll (not shown). Processed.

Next, external setup will be explained. In recent years, with the diversification of can sizes for canned beer, canned juice, etc., there is a demand for changing can lids to match the can size in a short time. height must be changed. According to the embodiment of the present invention shown in FIGS. 1 to 3, the can body guide turret lla which is inactive in FIG. Use the idle time while the coolet 11 is in operation to replace it and set it up externally.

When switching to the next step, the bracket 17 is manually rotated 180 degrees and fixed, and the can body guide turret Lla is then activated. Furthermore, if the height of the can is changed, the heights of the can body guide turrets ll and lla must be changed accordingly. In this case, by operating the lifting motor 35 shown in Fig. 3 and turning a threaded rod (not shown), the inactive can body guide turret) is raised or lowered to raise or lower the height of the can for the next process. Adjust it to

(Effects of the Invention) As explained in detail above, the present invention provides a plurality of can lid supply mechanisms and makes them switchable. You can use the extra time while the other can lid supply mechanism is in operation to change the can lid to the one that matches the can size in the process, so you can change it according to the next can size. This can be done in an extremely short time, greatly improving work efficiency.
