Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a rectangular container interval adjusting device for adjusting an interval for pitching a rectangular container at equal intervals when the rectangular container is continuously transferred in a pressed state along a conveyance path by a conveyor or the like. It is.
[0002]
[Prior art]
The prior art will be described with reference to FIGS.
The shape of the guide bar 18 that cuts between the rectangular containers 1 is required to have a sharp end suitable for interruption between containers and a thickness that can withstand vibration of the subsequent container.
Therefore, since the container contact portion at the tip of the guide bar 18 is an inclined side surface near the tip, an action of pushing back the subsequent container occurs when the space between the containers is interrupted. And this pushing back action becomes a vibration and leads to the necessity of a cam type constant velocity star wheel.
This vibration will be described in more detail. As shown in FIG. 8, when the rotation angle of the guide bar 18 is measured every 3 °, the distance traveled by the rectangular container becomes MIN 5.376 mm at MAX 7.557 mm, and as a result, the fluctuation range is 7.557-5.376 = 2. A fluctuation of 181 mm occurs. If there is such a change, for example, when many containers are accumulated on the supply container side, pulsation occurs and the final end container falls down. Such a container space | interval adjustment apparatus exists (for example, refer to Japanese Utility Model Publication No. 7-9854).
[0003]
[Problems to be solved by the invention]
However, in the above-described prior art, the claw, which is an engagement piece attached to the guide bar that comes into contact with the container, raises the falling container in order to cause a movement that causes pulsation in the rectangular container. In addition, there is a problem that noise due to the impact sound of each rectangular container is increased, the mechanism is complicated, and high performance and environmental resistance are uneasy.
[0004]
In addition, in order to use the existing constant speed rotary stopper with high capacity, followability must be ensured by a positive cam (groove cam) mechanism. Therefore, there is a problem that it does not match the atmosphere inside the rinser, such as the complexity of the mechanism and the problem of lubrication.
[0005]
In view of these circumstances, the present invention includes a rotary stopper that is rotatably supported and projecting a large number of thin plates that are supported by a shock absorber in a radial direction, and the rectangular plates are made to interfere with each rectangular container. It is an object of the present invention to provide a rectangular container interval adjusting device that adjusts the interval between containers.
[0006]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention includes a conveyance path of a rectangular container, and a large number of thin plates supported by a shock absorber that is rotatably supported along the conveyance path and absorbs the pulsation of the rectangular container in a radial direction. A technical means is provided that includes a projecting rotary stopper and regulates the interval between the rectangular containers on the transport path by causing the thin plate to interfere with each rectangular container.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
The present invention is an interval adjustment device that reduces pulsation of 50% or more with a thin plate in a rotary stopper, and further supports the thin plate with an impact absorber to reduce pulsation as much as possible. is there. The thin plate is made into a blade (blade) -like high-strength thin plate (for example, a carbon fiber base epoxy resin laminated plate), and, for example, elastic rubber or the like is used as an impact absorber for supporting the thin plate, thereby providing a bend, The pulsation (impact flow change) of the rectangular container on the conveyance path can be absorbed.
[0008]
【Example】
Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic plan view of a rectangular container interval adjusting device according to an embodiment of the present invention, FIG. 2 is an enlarged plan view of a main part of the rectangular container interval adjusting device of FIG. 4 is a schematic perspective view of a rotary stopper of the rectangular container interval adjusting device of FIG. 2, and FIG. 5 is a plan view showing details of a configuration in which one of the shock absorber and the thin plate of FIG. 4 is taken out. FIG.
[0009]
First, an overall image of the present invention will be schematically described with reference to FIG.
In accordance with the transfer of the rectangular container 1, the rectangular container 1 is conveyed by a conveying device 2 that pushes the rectangular container 1 in a row and conveys the rectangular container 1 in a pressed state, and a guide 3 that is adjustable on both sides of the upper surface of the conveying device 2. Are held and aligned.
[0010]
And the rotary stopper 5 which adjusts the space | interval of the rectangular container 1 conveyed by the alignment state of a presser at equal intervals is arrange | positioned in the side part of the conveying apparatus 2. FIG. The rectangular containers 1 that are equally spaced by the rotary stopper 5 are delivered to the timing screw 4 and further to the star wheel 6.
[0011]
Here, the detail of the said rotary stopper 5 is demonstrated in detail based on FIGS.
The rotary stopper 5 is connected to the shaft end flange portion 8 of the drive shaft 7 by bolts 9, and a large number of thin plates 12 are attached radially between a lower rotary substrate 10 that is driven to rotate in a horizontal state and an upper rotary substrate 11. The support 14 is provided.
[0012]
A spacer 15 is fixed between the upper and lower rotary substrates 11 and 10. Then, the support body 14 is fastened to the spacer 15 via the elastic rubber 13, and the plate 16 is further fastened to the spacer 15 via the elastic rubber 13. Further, a thin plate 12 is attached to the support 14.
[0013]
The thin plate 12 may be supported directly between the elastic rubbers 13 by omitting the support 14.
A thin plate (blade) 12 of the rotary stopper 5 is a high-strength thin plate made of a carbon fiber base epoxy resin laminated plate or the like that is slightly bent, and an elastic body such as an elastic rubber 13 that absorbs shock as shown in FIG. Since it is attached to the support body 14 via the bend, the flexible thin plate 12 moves.
[0014]
When this device is used for a rinser or the like, the material is made of a stainless steel material and a synthetic resin material in consideration of water resistance and sanitary properties.
[0015]
Therefore, it will be described with reference to FIG. 6 that the execution of the rectangular container spacing adjustment without failing in the case of using the rotary stopper 5 of the present invention is performed reliably.
When the thin plate 12 having a thickness of 1.2 mm is inserted between the rectangular containers 1 and the interval is adjusted, the succeeding container is pushed back.
In addition, since the pushback amount is small, the pushback vibration is not substantially generated due to the flexibility of the thin plate 12 and the elastic rubber 13.
[0016]
As can be understood from FIG. 6, the thin plate 12 is interrupted between the square containers 1, and the distance traveled by the square container 1 every 3 ° is MAX 6.913 mm and MIN 5.894 mm. As a result, the fluctuation range is 6. 913-5.894 = 1.019 mm, which is less than half of the conventional one, in other words, the pulsation of 50% or more can be reduced by the thin plate 12 alone, and the pulsation is supported by supporting the thin plate 12 with the elastic rubber 13. It can be reduced as much as possible.
[0017]
【The invention's effect】
The present invention can obtain the following effects based on the above configuration.
(1) When the rectangular container is adjusted at equal intervals, the container can be prevented from falling down.
(2) Since the pulsation is absorbed and there is no collision between containers, noise can be reduced.
(3) Maintenance can be facilitated.
