CONSTITUTION:When the assembly of respective horizontal rods 12 with the plate 11 positioned at the upper side is loosened and screw bars are regulated, the horizontal rods slide on the lower face along the direction crossing in right angles with the longitudinal direction and a couple of horizontal rods approach or separate each other. At the same time, respective guide pins 16 of the horizontal rods slide in the guide groove 15 of the adjacent horizontal rods. As a result, the mutual distances of four vertical rods 13 erected at the respective horizontal rods can be adjusted by regulation of the mutual distances of respective horizontal rods.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a spacing adjustment device for adjusting the mutual spacing of four vertical rods installed vertically.

<Prior art> When filling food products into a predetermined container, especially when filling a container with a large amount of liquid or semi-liquid products such as butter, margarine, jam, mayonnaise, chocolate, etc., it is necessary to fill the container with food to prevent leakage. A plastic bag is inserted, and the above-mentioned foodstuffs are filled into the plastic bag.

At this time, if the plastic bag is not tightly housed in the container, there is a problem that a gap will be created between the inner surface of the container and the plastic bag when it is filled with foodstuffs, resulting in damage to the plastic bag. However, it is undesirable from a hygienic point of view to manually store the plastic bags.

Therefore, FIG. 8 shows the case where the plastic bag 2 is mechanically stored in the container 1 as a preliminary step in this filling process.

That is, a plastic bag 2 is temporarily stored in a container 1 whose top is open, and the container 1 that is transported in this state stops at a predetermined position. Then, the plastic bag 2 is pushed open by four vertical rods 3 descending from above, and the 9th
As shown in the figure, the four corners are in almost perfect contact with the inner surface of the container 1, and the container 1 is sent to the next filling process.

<Problems to be Solved by the Invention> The container 1 described above has various sizes depending on the type of food to be filled or the amount of food to be filled, etc. Therefore, the plastic bag 2
The mutual spacing of the four vertical rods 3 that spread out the container 1
must be varied depending on the size of the

However, adjusting the mutual spacing of the four vertical rods 3 requires extremely great effort and precision, and replacing the entire device also poses similar problems. The present invention was invented to solve the above-mentioned problems, drawbacks, and inconveniences that have not been solved in the past, and is a spacing adjustment device for adjusting the mutual spacing of four vertical rods installed vertically. A guide groove is provided along the length on the inner surface, a guide pin is provided protruding from the distal end surface, and the vertical rod is vertically disposed at the distal end to form a horizontal rod, and the four horizontal rods are connected to each other. , the guide pins are slidably fitted into the guide grooves of adjacent horizontal rods and assembled in a substantially cross-shaped configuration, and a pair of opposing horizontal rods is connected with a screw rod, and each horizontal rod is positioned upward. This is a spacing adjustment device that is assembled to the lower surface of a plate that is slidable along the direction perpendicular to the length direction.

<Operation> Therefore, when the assembly between each horizontal rod and the plate located above is loosened and the screw rod is operated, the horizontal rod slides on the lower surface of the plate along the direction perpendicular to the length direction, and the horizontal rod The rod approaches and separates. At the same time, each guide pin of this horizontal rod slides in the guide groove of the adjacent horizontal rod.

As a result, by adjusting the mutual spacing of each horizontal rod, the mutual spacing of the four vertical rods vertically disposed on each horizontal rod can be adjusted.

<Example> The present invention will be explained below based on drawings of embodiments.

FIG. 7 shows a case in which the spacing adjustment device of the present invention is used in a device used to tightly store a plastic bag in a container before filling the container with a liquid or semi-liquid product. , four vertical rods 13 are vertically installed on the lower surface of the plate 11 via horizontal rods 12,
By moving the plate 11 up and down through the cylinder 14, the four vertical rods 13 are moved up and down, and the plastic bags temporarily stored in the container are tightly stored by the four vertical rods 13.

The horizontal rod 12 has a rectangular bar shape with a predetermined length, has a guide groove 15 along the length direction over about half of the inner surface near the proximal end, and has a guide pin 16 protruding from the distal end surface. Rail grooves 17 are provided along the length direction in about half of both sides near the tip, and through grooves 18 are provided vertically penetrating in about half of the proximal end and about half near the tip. The vertical rods 13 are provided along the length direction, and the above-mentioned vertical rods 13 are hung from the inner surface of the tip end.

The horizontal rods 12 having such a configuration are assembled in the shape of a four-way grid. At this time, when the horizontal rods 12 are adjacent to each other, the guide pin 16 of one horizontal rod 12 is connected to the guide pin 16 of the other horizontal rod 12. It is slidably fitted into the groove 15.

The guide pin 16 and the guide groove 15 are engaged with each other in a so-called dovetail fitting structure, so that they do not come out in a direction perpendicular to the length direction.

Therefore, in the horizontal rods 12 assembled in a cross-shaped configuration, a pair of opposing horizontal rods 12 move toward and away from each other as the guide pins 16 and guide grooves 15 mutually slide. This approach and separation is caused by the pair of horizontal rods 12 facing each other.
This is achieved with a screw rod 19 that connects the two.

That is, each horizontal rod 12 is fitted with a bracket 20 that straddles the lower surface of the rod and locks into both rail grooves 17 and slides along the length direction. The screw rod 19 is screwed through the bracket 20.

Therefore, by rotating the screw rod 19 in a predetermined direction, the pair of horizontal rods 12 are moved closer to each other and away from each other. , is held by a holding material 21.

Next, to attach the horizontal rod 12 to the lower surface of the plate 11, a hanging bolt 22 is used.

That is, along the direction perpendicular to the length direction of the horizontal rod 12, that is, the through groove 18 is formed in the portion of the plate 11 that faces the two through grooves 18 provided vertically through each horizontal rod 12.
along the direction perpendicular to the holding groove 23,
A hanging bolt 22 is passed through from the upper side of the holding groove 23 to the lower side of the through groove 18, and the lower part is fastened with a nut 24.
The horizontal rod 12 is integrated with the plate 11.

In the above-described configuration, in order to fluctuately adjust the mutual spacing between the four vertical rods 13 hanging at predetermined intervals, first loosen the nuts 24 so that the horizontal rods 12 freely touch the bottom surface of the plate 11. The horizontal rods 12 are brought into a slidable state, and then the screw rods 19 are rotated in a predetermined direction to move each pair of opposing horizontal rods 12 toward each other and away from each other.

During this operation, as described above, the horizontal rod 12 mutually slides by the guide of the guide pin 16 and the guide groove 15, and moves in the length direction and in a direction perpendicular to the length direction. is ensured by the through grooves 18 provided along the length direction, and movement in the direction orthogonal to the length direction is ensured by the holding grooves 23 of the plate 11. When moving in the length direction, the bracket 2o that holds the screw rod 19 has one rail groove 17.
It moves along the

Although the present invention has been described above with reference to the embodiments shown in the drawings, the present invention is not limited to the above-described embodiments, and can be implemented in any manner as long as the configuration described in the claims is not changed.

For example, even if the guide pin 16 is provided protrudingly on the inner surface of the horizontal rod 12 and the guide groove 15 is provided on the distal end surface, the above-mentioned effects can be sufficiently achieved.

<Effects of the Invention> In summary, according to the present invention, by adjusting the mutual spacing of each horizontal rod, the mutual spacing of the four vertical rods vertically disposed on each horizontal rod can be adjusted extremely easily and accurately. It has excellent functions and effects, such as making it possible to replace the entire device and eliminating the need to replace the entire device.
