Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container transporting device which transports containers arranged on a transporting conveyor at an irregular pitch by rearranging them at a predetermined wide pitch interval.

[0002]

2. Description of the Related Art A conventional example of a transporting device for transporting objects to be transported such as containers in a predetermined wide pitch interval is as shown in a plan view of a main part of FIG. 7 and a front view of a main part of FIG. A pair of timing screws 10 is provided above the conveyor 101.
2, 102 are provided. Although FIGS. 7 and 8 show the conveyor conveyor 101 of the chain drive slat conveyor type, they may be of the belt conveyor type.

In a chain-driven slat conveyor type transfer conveyor 101, a large number of plate-like pieces 103 arranged with almost no gap are fixed to two endless chains (not shown). By the rotation of the drive sprocket (not shown) and the rotation of the drive sprocket, the transported object placed on the plate-shaped piece 103 is transported from the loading side (left side in FIG. 7) to the unloading side (right side in FIG. 7).

A set of timing screws 102, 10
No. 2 is arranged so that its axis is parallel to the conveying direction of the conveyer 101, the shaft portions 104 provided at both ends are rotatably supported by bearings (not shown), and the timing screws 102, 102 are mutually Rotate at the same speed in the opposite direction.

A screw portion 105 whose pitch increases in the carrying-out direction is provided between the shaft portions 104, 104. The screw portion 105 is a spiral guide 1 corresponding to a screw thread.
06 and a spiral groove 107 corresponding to the screw bottom, the spiral grooves 107 of the two timing screws 102 face each other to form an accommodation space 108 for accommodating the transported object,
The accommodating space 108 moves in the carrying direction of the carrying conveyor 101 as the timing screws 102, 102 rotate.

The transport of the container B by the transport device configured as described above will be described. The containers B loaded on the loading side (the left side in FIG. 7) of the transport conveyor 101 have irregular intervals. Since it is conveyed and abuts on the tip surfaces of the two timing screws 102 to prevent conveyance,
The bottom surface of the container B slips on the conveyor 101.

The next container B that has been conveyed comes into contact with the container B that is in contact with the tip end surface of the timing screw 102 and is blocked from being conveyed, so that a plurality of containers B are no longer spaced from each other. Is accumulated on the conveyor 101. And the timing screw 102
Rotation of the container causes the container B, which is in contact with the tip end surface of the timing screw 102, to move to the two timing screws 1
Accommodation space 108 constituted by 02 spiral groove 107
And is inserted into the accommodation space 108 as the timing screw 102 rotates.

As described above, the pitch of each accommodation space 108 gradually increases as it moves in the carrying direction,
The container B reaching the rear end of the timing screw 102 is
The interval with the next container B that has been transported to the unloading end and reached the rear end at the transport speed of the transport conveyor 101 is a predetermined pitch interval.

As described above, the container intervals, which were irregular intervals on the carry-in side of the conveyer 101, are conveyed to the carry-out side in an orderly arranged state after passing through the timing screw 102. Then, in the next step, the liquid is filled in the container B which is transported at a predetermined pitch interval and whose positioning is stopped.

9 is a plan view of a main part of FIG. 9 and a front view of the main part of FIG. 10 show another conventional example of a transporting device. Instead of one of the timing screws 102, a guide rail 109 is provided. The guide rails 109 are arranged in the upper and lower sides, are parallel to the conveyance direction of the conveyance device 101, and have the spiral groove 107 of the timing screw 102 and the guide rail 10.
9, a storage space 110 for the container B is formed, and the rotation of the timing screw 102 moves the storage space 110 to the right in the drawing.
The increase in the pitch is similar to the prior art example.

[0011]

Since the container B has various shapes, the timing screw 102 must be replaced according to the diameter of the container B. Therefore, it is necessary to prepare various timing screws 102, and the timing screw 1 is required every time the container B to be transported is changed.
The replacement work of 02 required a lot of time and labor. In particular, when the timing screw 102 is long or heavy, there is a problem that replacement work is not easy.

The outer peripheral surface of the container B excluding the bottleneck is marked with the liquid contained therein and the type of the container. However, the moving speed and the transportation of the container B, which is constrained by the timing screw 102, are conveyed. There is a problem that the outer peripheral surface of the container B is scratched due to the difference in speed with the conveying speed of the conveyor 101, and the appearance of the outer peripheral surface marked is impaired. The present invention aims to solve such a problem, paying attention to the small change in the diameter of the bottleneck with respect to the change in the diameter of the container, making it possible to adjust the size of the accommodation space of the timing screw, and By providing a bottleneck of a container in the accommodation space, the present invention provides a container transporting device that can be used also for containers of various sizes.

[0013]

In order to achieve the above object, a container carrier of the present invention comprises a carrier conveyer for carrying a plurality of containers having bottlenecks formed on the upper part thereof in a line in a predetermined direction, and the carrier. An outer peripheral surface of a rotating shaft, which is rotatably supported at both ends by a support base that can be moved up and down above the conveyor and a bearing provided on the support base, and has an axis parallel to the transfer direction of the transfer conveyor. And a timing screw having a spiral guide whose pitch gradually increases in the transport direction, and accommodates a bottleneck of a container transported on the transport conveyor in a storage space formed in the spiral guide. To do. The spiral guide of the timing screw has a first pitch gradually increasing on the outer peripheral surface of the rotating shaft in the transport direction.
And a second spiral guide formed in the same shape as the first spiral guide. The first spiral guide and the second spiral guide are connected to the rotary shaft. It is possible to move in the axial direction, and the accommodation space formed between the two spiral guides can be made variable.

[0014]

In the container transporting device configured as described above, the bottleneck of the container transported by the transport conveyor contacts the front end face of the timing screw, and the rotation of the timing screw causes the container that was in contact with the front end face to move. The containers are successively accommodated in the accommodation spaces of the timing screws, the pitch of each accommodation space is expanded to a predetermined interval while moving to the rear end of the timing screws, and the pitch of the containers conveyed by the conveyor after passing the timing screws is constant. And sent to the next process.

Further, when an improved spiral guide is formed by stacking two spiral guides of the same shape like a double screw,
By adjusting the position of the spiral guide, the container can be changed by simply adjusting the size of the accommodation space formed between the first spiral guide and the second spiral guide to the size of the bottle neck of the container. The preparation work of is completed.

Since the container moves on the conveyor while the bottleneck is restrained, there is no risk of scratches on the marked outer peripheral surface.

[0017]

Embodiments of the present invention will be described with reference to the drawings. FIG. 6 (A) is a front view of a small container B ₁ , FIG.
(B) is a front view of B ₂ of a large container. Container B ₁
Both B and B ₂ are bottleneck N with small diameter at the top.
₁ , N ₂ are formed, and a female screw (not shown) formed on the inner surface of the stopper 3 is screwed into the male screw 2 provided at the tip of the stopper 3. However, since the type of the stopper 3 is limited, the bottleneck N ₁ , N ₂ are also limited in diameter.

Therefore, even if the diameters of the container B ₁ and the container B ₂ are different, the diameters of the bottle necks N ₁ and N ₂ may not change, so that the bottle neck is accommodated in the accommodating space of the timing screw and conveyed. By doing so, it becomes possible to use the timing screw as well. Further, even when the diameters of the bottle necks N ₁ and N ₂ are changed, the difference in diameter is small, so that the adjustment amount of the size of the accommodation space of the timing screw can be small. The present invention pays attention to such an actual situation, and accommodates the bottleneck of the container in the accommodation space of the timing screw and adjusts the size of the accommodation space.

FIG. 4 is an arrow A diagram of FIG. 2 and FIG. 5 is the timing screw 1. FIG. The inner surfaces of the semi-cylindrical bodies 12, 13 movably contact the outer peripheral surface of the rotating shaft 7.

The semi-cylindrical bodies 12 and 13 have a shape obtained by bisecting one semi-cylindrical body in the longitudinal direction. By stacking the semi-cylindrical bodies 12 and 13, one semi-cylindrical body is formed. The rotary shaft 7 is inserted into the inside of the. Two holes 14 and one screw hole 15 are provided on both end surfaces of the half cylinders 12 and 13, respectively.

Discs 16 and 17 are fixed to both ends of the rotary shaft 7, and four guide rods 18 are provided on the discs 16 and 17, respectively.
Is fixed, and the two movement adjusting screws 19 are rotatably fitted. Then, the guide rod 17 is inserted into the hole 14,
The movement adjusting screw 19 is screwed into the screw hole 15. Therefore,
When the head 19a of the movement adjusting screw 19 is rotated using a tool, the half cylinders 12 and 13 are guided by the guide rod 17,
Each independently moves along the outer peripheral surface of the rotating shaft 7.

A spiral guide 10 is provided on the outer peripheral surface of the half cylinder 12.
Is fixed (see FIG. 2), and the spiral guide 11 is fixed to the outer peripheral surface of the half cylinder body 13 (see FIG. 3).
When 3 are combined into one tubular shape, the spiral guide 10
And 11 are formed on the cylindrical outer peripheral surface like double screws,
A spiral groove is formed between the spiral guides 10 and 11. Then, when the movement adjusting screw 19 is turned, the positions of the spiral guides 10 and 11 are moved, and the width of the accommodation space 20 in the axial direction can be changed.

The two timing screws 1 having the above-described structure are arranged in parallel in the conveying direction of the conveyer, and the bottle necks of the containers B ₁ and B ₂ are placed between the spiral grooves of the timing screws 1. A container B is formed in which an accommodation space for accommodating N ₁ and N ₂ is formed, and both timing screws 1 and 1 are rotated in opposite directions at the same speed and accommodated in the accommodation space.

Alternatively, as shown in FIG. 1, a guide rail 20 parallel to the carrying direction is provided to restrain the bottle necks N ₁ and N ₂ in the spiral groove of one timing screw 1.
Similar to the conventional example, the outer peripheral surfaces of the containers B ₁ and B ₂ may be moved in the arrow F direction while being guided by the guide rail 15.

The operation of the container transporting device configured as described above will be described. After the transfer of the container B ₁ is completed, in order to prepare for the transfer of the container B ₂ , the support base 5 is raised so that the height of the timing screw 1 becomes the height of the bottleneck N ₂ , and the movement adjusting screw 19 is set. The semi-cylindrical bodies 12 and 13 are rotated to move, and the first spiral guide 10 and the second spiral guide 11 are moved.

_When the size of the bottleneck N ₂ of ₂ is adjusted, the container B ₂ is ready for transportation.

Next, the transfer conveyor and the timing screw 1 are operated to supply the container B ₂ to the loading side of the transfer conveyor. The container B ₂ is conveyed at irregular intervals in the direction of the arrow F, and the first spiral guide 1 of the timing screw 1 is conveyed.
0, the plurality of containers B ₂ are accumulated on the conveyer at the front end surface of the second spiral guide 11, and the rotation of the timing screw 1 causes the first spiral guide 10 and the second spiral guide 11 to rotate. It is inserted one after another into the accommodation space constituted by 11 spiral grooves.

The rotation of the timing screw 1 gradually increases the pitch of the accommodating space that moves in the direction of arrow F, and as the container B ₂ accommodated in the accommodating space moves in the same direction, the interval between the containers B ₂ also increases, and the timing is increased. The container B _{2 that} has passed through the screw 1 reaches the carry-out side of the conveyor while maintaining a constant interval, and is supplied to the next process while maintaining a predetermined interval.

A slip occurs between the outer bottom surface of the container B ₂ and the transfer conveyor due to the difference between the moving speed of the container B ₂ which is stored in the storage space of the timing screw 1 and moves and the transfer speed of the transfer conveyor. Since the container B ₂ has the bottleneck N ₂ accommodated in the accommodating space of the timing screw 11, there is no risk of scratches on the display mark provided on the outer peripheral surface of the container B ₂ as in the conventional container conveying device. Absent.

[0030]

Since the present invention is constructed as described above, it has the following effects. The present invention is
Focusing on the fact that the size of the bottleneck does not change much even if the size of the container changes, the bottleneck of the container on the conveyor is now accommodated in the timing screw accommodation space, so the timing screw accommodation space is changed. In some cases, it is possible to convey containers of different sizes without doing so, which reduces the labor and time required for the preparatory work.

When two spiral guides, such as a double screw, are constructed so that they can be moved, the size of the storage space becomes variable, and the timing is changed even when the size of the bottle neck of the container changes. The screw can now be used for containers of various sizes. Therefore, the preparatory work for changing the size of the container to be transported becomes extremely simple, and the labor and time required for the preparation can be greatly reduced.

Since the container on the transport conveyor is accommodated in the accommodating space of the timing screw, the conventional problem that the outer peripheral surface of the container marked with the mark is scratched is solved.
