[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to an apparatus for adjusting bottles, which are continuously conveyed without gaps, at a predetermined interval in accordance with a box structure when the bottles are packed.

[0002]

2. Description of the Related Art Bottled goods go to the market after being packed in various types of boxes. However, even boxes packed with the same beverage bottle can be of various types, from plastics to old wooden ones. It is. For example, one sho bottle of sake is packed in a plastic box or a wooden box, and the number of packages is also different.
In addition, the difference between plastic and wooden materials
Not only the thickness of the partition plate and the reinforcing frame are different, but also the structure is different, which makes automation of box packing difficult.

[0003]

[Problem to be Solved by the Invention] This invention solves the problem that the bottle interval can be changed at the time of packing according to the difference in the bottle interval derived from the difference in the material and structure of the packing box. It should be a task to be done.

[0004]

According to the present invention, there is provided a type of bottled product which is continuously conveyed to a boxing place without any gaps, and is provided on a board supporting the bottled product after automatic chucking of a predetermined number at the time of boxing. The cam operation means of (1) employs a structure in which the intervals between bottles are expanded at equal intervals or irregular intervals according to the structure of the box, thereby achieving the intended purpose.

That is, in the apparatus for adjusting the bottle interval to a predetermined interval according to the present invention, the distance from the center of rotation is set to a position corresponding to the diameter of the bottle or the like, and a plurality of strips having different lengths or shapes are provided. A board body having a long hole formed therein, a stationary bottle chuck having an appropriate structure provided at the rotation center portion, located on the lower surface of the board body, and located on both left and right sides of the stationary bottle chuck.
Around the rotation center portion, a rail provided rotatably relative to the board, and provided movably along the rail, the same type as the former, the bottle chuck group together with the stationary bottle chuck. The object is solved by individually and movably engaging pins formed on the movable bottle chuck and projecting above the movable bottle chuck into the long holes of the board body.

[0006]

The bottled goods conveyed without gaps are automatically chucked first by the bottle chuck group. Subsequently, the bottled product in the chucked state is moved to above the packing box. As a moving means in this case, for example, a no-load balancer is used. While moving the box above, the device is operated to horizontally rotate the rail supporting the bottle chuck group leftward or rightward with respect to the board.

In FIG. 1 showing the embodiment, when the rail is rotated, for example, counterclockwise, the pins protruding from each bottle chuck move pointwise symmetrically along the elongated holes formed in the board body. Bottled products that were initially lined up in the horizontal direction without any gaps are proportionally enlarged in bottle interval while being suspended by the bottle chuck group. Further, when the rail is rotated clockwise, the pins move along the elongate holes formed to be asymmetry, so that some of them are spread at irregular intervals and others are spread at equal intervals.

[0008] Since the above-mentioned equidistant or unequal interval is a dimension previously adjusted to the structure of the box, in this state, the no-load balancer can be lowered to put the bottled goods in the box. When the rail is rotated right (left) to the original position in the left (right) rotation state, the bottle chuck returns to the original standby state. This state is the chuck standby state of bottled goods or empty bottles conveyed without gaps described at the beginning of this section.

Reference numeral 14 denotes a horizontal arm fixed to the upper end of each pin 12, and a free end thereof is provided with a ball 15 which moves in contact with the upper surface of the board 1.

Next, in FIG. 2 and FIG.
7 is a bearing installed on the upper surface of the board 1, 18 is a bearing 16,
17, the rails 6, 6 'when in the standby position.
The catch arms 20 and 21 which can be rotated in either of the right and left directions by the rotation of the operation handle 19 are fixed to the rotation shaft, and the free ends of the arms are fixed to the rotation shaft. FIG. 1 pierced at an appropriate position on the board 1

The stopper 25 is configured to engage with the roller catch 30 when rotated leftward to the upper side.

Next, the operation of this embodiment will be described. It is assumed that the bottled products are continuously conveyed by a belt conveyor (not shown) without gaps and arrive at the installation location of the invented device, and it is assumed that the boxes C for packing the bottled products are in two rows with one row of five bottles. In the case of a box C packed with 5 bottles in one row, the thickness of the plate or reinforcing plate separating
Assuming that the distances between the centers of the bottled products are the same as each other assuming that they are the same as shown in FIG. By rotating until reaching the straight line A-A, as described below, a required gap between each bottling product, that is, a distance separated by a distance corresponding to the thickness of the partition plate or the auxiliary plate C1 is set. Keeping the bottle spacing evenly widened.

Further, it is assumed that the boxes C are four rows in one row and two rows, and that the partition plate C2 provided at the center of the box C is extremely thicker than the other partition plates C3 in terms of reinforcement. In this case, the distance between the center point P1 and the operation end point P2 'is widened by rotating the rails 6, 6' rightward on the virtual straight line BB in FIG. Gaps are formed between the bottled products at so-called unequal intervals where the distance between P2 'and P4' and the distance between P1 and P3 'are equal.

When the intervals between the bottled products are to be increased at equal intervals, the bottle chucks 2-1, 2-2, and 2--2 wait for the bottled products continuously conveyed without any gap.
According to 3, 2-4, and 2-5, five pieces are chucked and lifted at the same time, guided directly above the box C, and lowered.
Subsequently, when the rails 6 and 6 ′ are horizontally rotated leftward while holding the operation grip 27, all protrusions of the bottle chucks 2-2 to 2-5 respectively engaging with the slots 8, 9, 10 and 11 are respectively. The setting pin 12 moves along the long holes 8 to 11 and the rail 6
Is engaged with the roller catch 30 provided on the board 1. Then, the rotation of the rails 6, 6 'is stopped, and the direction of the rails 6, 6' coincides with the virtual straight line AA in FIG. In this case, the straight holes 8a and 9a of the slots 8 and 9 formed in the board 1 have the same length, and the slots 10 and 11 have the same length of the straight holes 10a and 11a. Since the length is twice as long as the straight holes 8a and 9a, the gap between the bottled products is equally widened to a distance corresponding to the thickness of the partition C1 of the box C.

In this state, all the bottle chucks 2-1 to 2-2
When the supply of pressurized air to -5 is stopped and the air is exhausted, the five bottled products will fit in one row in box C at the same time. Subsequently, when the same operation as described above is repeated, 1
Zero bottled products are stored in two rows.

Next, in the case where the interval between the bottled products is expanded only partially, that is, at irregular intervals, the bottled products conveyed without gaps are similarly placed in the bottle chuck 2-1 for standby. The two rails are simultaneously chucked and lifted by 2-2, 2-3, and 2-4, and the rails 6, 6 'are horizontally rotated clockwise. At this time, all the projecting pins 12 of the bottle chucks 2-2 to 2-5 respectively engaged with the elongated holes 8, 9, 10, and 11 move along the elongated holes 8 to 11, respectively. When the stopper 26 fixed to the rail 6 'is engaged with the roller catch 31 provided on the board 1, the rotation of the rail 6, 6' is stopped, and the direction of the rail 6, 6 'is the imaginary straight line in FIG. B
It matches with -B.

In this case, the long holes 8 formed in the board 1
Are formed perpendicular to the rails 6 and 6 'at the neutral position, and the center point P1 of the pin 4 which is the center of rotation of the rails 6 and 6' and the operation end point P2 of the slot 8 ′ Is the end point of action P of the other slots 9, 10, 11
The bottle chucks 2-2, 2-, which are long away from the pin 4 and are for chucking bottled products, by the amount that 3 ', P4', and P5 'are curved in the direction of the center point P1 of the pin 4.
3, 2-4 is the distance L between the action end points P2 'and P4'.
Since the distance L3a between 4a and P1 · P3 'is set to be equal, the gap between the bottled products is expanded in one place to a distance in consideration of the thickness of the central partition C2 of the box C, and in other places, It is spread equally to the distance corresponding to the thickness of the partition plate C3.

In this state, as described above, the bottle chuck 2
When -1 to 2-4 are operated, four bottled products are simultaneously stored in one row in the box C. Subsequently, when this operation is repeated, the box C contains eight bottled products in two rows.

Although one embodiment has been described above, in the present invention, the stationary bottle chuck 2-1 is provided not at the center of the panel body 1 but at the end thereof, and one of the left and right sides of the bottle chuck 2-1 is provided. It is also possible to arrange a movable bottle chuck at a position.
The slots 8, 9, 10, 11 are elongated slots 8a, 9a, 10a, 1 for extending the bottle interval at equal intervals on one board 1.
Slots 8b, 9b, 10b, 1 extending at irregular intervals from 1a
1b may not be formed in a series, and in implementation, even if one of the slots for the equal interval expansion or the unequal interval expansion is formed in one board 1, The goal can be achieved.

The diameter of the bottle varies depending on the product, and the size of the box C, the position of the partition plate, the reinforcing frame and the like, and the thickness of the box C also vary with the diameter of the bottle. By setting the length or changing the shape, it becomes possible to use it as a means for extending the interval of any bottled product or packaged product.

[0031]

According to the present invention, as apparent from the description of the above embodiment, the interval between the bottle chucks for suspending bottle products is freely adjusted to a desired interval by one kind of cam action provided on the panel body. It can be changed, and the main composition is
With only the rotating rail supporting the disk body and the plurality of bottle chucks, it is possible to achieve the desired interval expansion effect simply by the horizontal rotation operation of the rail, so the structure and function are simple, There is an excellent effect that it is easy to handle and there is no component causing a failure.

The present invention has a feature that it is easy to maintain and can be easily operated by anyone even if it is not a skilled person. Further, since the present invention does not require any power source, the non-load balancer can be used. By installing the balancer, there is also an effect that the field of use of the balancer can be further expanded.
