The grooves 25 are formed in a continuous manner, and a round belt is supported and moved by these grooves 25.

The rails 27a, 27b are fixed to the frame 2 at appropriate locations by mounting plates 26.

Side guides 28 and 29 are fixed along the front-rear direction to the rising portions on both sides of the frame 2 to prevent a can or the like from coming into direct contact with the frame 2.

In addition, the rails 27a, 27b and the side guide 28
．． 29 is provided not only in the portion having the round belt groups A and B shown in FIG. 5, but also in the portion having the round belt groups B and C.

As shown in FIGS. 1 and 5, rails 27a and 27b
Blocks 30 are fixed at two locations, front and rear, between the two.

As shown in Figures 1 and 6 a and b, round belt groups A and C
In the part between, the axes 6 and 7 are Boo') 9 a, 9
Round belt A1.b supported by large diameter portion 22.b. A round bar 31 is provided between C1 with almost no gap between them,
These round bars 31 are fixed to a support member 33 fixed to the frame 2 by a support rod 32 to form a transfer section, and a round belt A1 for a can or the like is connected. This ensures smooth transfer between C1 and C1.

As shown in FIGS. 1, 2, 7, 8, and 9, four both-side support round bars 34a and 34b are combined so as to be almost in contact with the front ends of the round belt groups B and C. The rear end of a chute 35 is disposed, this chute 35 extends diagonally forward and downward, and a frame body 36 for fixing a group of round bars is installed in the middle part, and a T-shaped upright stopper 37 is installed on this frame body 36. An upper guide bar 38 is located above the stopper 37 and is protruded from the top.
The rear end portion 38a is bent obliquely rearward and upward.

An upper guide rod 38, a bottom support rod 39 connected to the upright stopper 37, an upper both-side support round rod 34a, and a lower both-side support round rod 34c extend diagonally rearward and downward from the frame 36, and are approximately on the lower surface of their front ends. The transport conveyor 4
0 is set.

Note that the lower both side support round bars 34b and 34c are part of the frame 36, and the front one is disposed slightly upward.

Next, a method of arranging the cans using the arranging device configured as described above will be explained.

When sealed cans with their contents are fed in a disorderly manner from the left side of Figures 1 and 2 onto the conveyor made up of round belt groups A and B, Figure 10 a"'-e is shown. As shown, the can 41 constitutes one series of four round belts A1 t A
2 t B1 y rest on at least two B2,
It is transported to the right in FIGS. 1 and 2.

As shown in FIG. 10a, the can 41 is connected to the guide rail 27a.
This is a case where the can 41 is placed horizontally between the convex portions with the front-rear direction and the axial direction of the can 41 substantially matching, which is the most stable state.

Then, the can 41 is supported by the lower round belt A2 t B2 supported by the recessed portion of the rail 27a, and is conveyed as it is.

In this case, the moving speed of the round belt is B1> as described above.
B2>A1>A2, and a twisting force acts on the can 41 due to the speed difference between the round belts A2 and B2, but the can 41 is connected to the upper round belt A1.
Since it is sandwiched between B1, it is transported forward in the state shown in FIG. 10a.

Figure 10 shows that the axial direction of the can 41 stands up obliquely and is perpendicular or inclined to the rail 27a and the longitudinal direction, and is supported by the upper round belts A1 and B1, and the lower round belt between them. A2. This is a case where it is not supported by B2.

In this case, a moment is generated in the can 41 due to the difference in moving speed between the round belts A1 and B1, and the can 41 is conveyed while changing direction as shown in FIG. 10a.

In Figure 10C, the axial direction of the can 41 is horizontal and the rail 2
The upper round belt A1 supported by the convex portion of 7a. This is the case where B is supported.

In this case, it is in the second most stable state after FIG. 10a.

However, even in this case, a moment is generated in the can 41 due to the difference in the moving speed of the round belts A1 and B1, and since the block 30 is provided between the rails 27a, the situation shown in FIG. Finally, the direction is changed and conveyed as shown in FIG. 10a.

In FIG. 10d, the can 41 is connected to the round belt A1. In this case, a moment is generated in the can 41 due to the difference in moving speed between the round belts A1 and B2, and the first
It is transported by changing its direction as shown in Figure 0a.

Although not shown, the round belt B1 of the can 41. The same applies when supported by A2.

Furthermore, as shown in FIG. 10e, the distance between the convex portions of the rail 27a and the distance between the upper round bells mA1tB1 are made smaller than the diameter of the can 41, so that the can 41 stands upright and the round bell Even when supported on l' Al t Bl, the can 41 will fall due to the moment due to the difference in these moving speeds,
Either the state of Figure 10a is reached directly, or the state of Figure 10b-
After passing through the state of d, it becomes the state of FIG. 10a and is transported.

Note that the above description is based on the round belt A2. supported by two adjacent rails 27a. A2. B1. Although this was done for the case of the series consisting of B2, the same applies to the case of the series consisting of round belts of rails 27a and 27b.

The cans are arranged as described above, but the problem is that as shown in Figure 11, the cans are in the states shown in Figures 10a and 10C, where the cans are closely spaced and continuous. This is the case.

In such a case, the intermediate unaligned cans 41',
Even if a moment is generated by the round belt 41', the round belt A1. A, 2°B1. Only B2 cannot change the orientation of the cans 41', 41' which are not aligned.

However, as shown in Figures 1, 2, and 6 a and b,
Maru Peru - A transfer section having a round bar 31 is provided between A1 and C1, and as mentioned above, the round belt has C1.
〉Since there is a speed difference of B1>A1, the can force S is at the speed of B on the entrance side of the transfer section and the speed of C1 on the exit side. They are aligned due to the speed difference between round belts B and C1 (7) Can 4
1' and 41' should also be aligned as shown in Figure 10a.
This will happen.

The cans 41', 41', which are not aligned due to the speed difference between the round belts B1 and C1 due to a gap between them, are now aligned as shown in FIG. 10a.

In addition, the can 41 in the states of FIGS. 10b to 10e is the round belt group A,
Even if it remains in the 8th part, it will transfer from the round belt group A and 8th part to the B and C parts together with the aligned cans, and the same alignment action as the former will be performed in the latter part, so from the B and C parts. All the cans are aligned so that their axes run along the front-rear direction and are carried out.

The cans that have been arranged and taken out are shown in Figures 1, 2, and 7.
As shown in FIG. 9, slide down the chute 35 and
The bottom of the can 41 hits an upright stopper 37 provided at the top of the can 41 to raise it up, and the can 41 is led onto a conveyor 40 in the upright state, and conveyed by this conveyor 40.

In this case, the can is round belt group B. Since there is a gap between the cans when they are transported from C, the cans do not interfere with each other when the cans are stood up.

In addition, in this invention, in the above-mentioned embodiment, the cans are arranged in nine rows, and the rear part is raised up and sent to the next process, but the number of rows is limited to nine rows if there are multiple rows. It is not necessary to provide a means for raising the can.

However, when considering handling in the next process, it is necessary to stand the can upright, so if you do as in the example, you can easily stand up the can without using a complicated mechanism, which saves labor. It is also advantageous in terms of conversion.

Further, in the present invention, when a large quantity of cans is supplied at once, it is preferable to provide a baffle plate or the like above the group of round belts to break up the pile of supplied cans.

Furthermore, the present invention is not limited to cans, but can be broadly applied to cylinders that can stand up on their own or containers having a shape similar to a cylinder.

As explained above, according to the automatic cylindrical body alignment device of the present invention, cylindrical bodies that can stand up on their own, such as cans, can be aligned continuously and quickly while being conveyed, and the alignment work can be carried out continuously and quickly. Not only can efficiency be greatly improved, but labor costs can also be greatly reduced.

Further, according to the automatic cylindrical body alignment device of the present invention, even if a large number of cylindrical bodies as described above are supplied at the same time, it is possible to reliably align the cylindrical bodies in any form during transportation after supply. It has an extremely reliable alignment ability.
