Description

[Detailed description of the invention] (Industrial application field) This invention relates to the hanging of thin packaging materials, and is used in supermarkets and other stores to stack packaging materials such as resin film packaging bags and enclosed paper on top of each other. This makes it easy to hang the thin packaging material 31 one by one from above or below, and also makes it easy to hang new packaging material.

(Prior art) As shown in FIG. 6, conventional thin packaging materials have two parts at the front and rear parts of the material hanging area of the thin material hanging arm a.
A material presser b, b is provided, and a vertically movable rod c with the upper end of the material presser attached is passed through the upper surface of the arm a,
A spring d is provided below the arm a, and the material presser b is lowered by the reduction of the trapped packaging material and the elasticity of the spring d. However, when loading additional packaging material, if there are two material pressers, the rear material presser must be raised and clamped, then the front material presser must be raised and the material presser must be lowered under it, making operation difficult. There are some drawbacks.

(Problems to be Solved by the Invention) Most of the thin packaging materials hung on the material hanging arm are made of resin film and have good sliding properties.
Therefore, in most cases, you can grab one piece with your right hand and pull it upward or downward to separate it, so you only need to press the front of the material hanging arm with the material presser, and we confirmed that it is more effective if you press it from the side. Obtained. The present invention takes account of this experimental fact and allows the material presser to be turned to the side and locked when hanging. The purpose is to provide a device that is extremely convenient to use.

(Configuration for Solving Problems) The present invention constitutes a means for achieving the above-mentioned object, and includes forming the base 16 into a substantially inverted U-shape, and one protruding rod 17 of the base 16. Extension piece 19 approximately parallel to the side surface of the thin material hanging arm 5
The inner corner of the base 16 of the material presser 15 is provided with a presser piece 21 in contact with the side surface of the arm 5 at the tip of the extension piece 19, and the inner corner of the base 16 is fixed to the rotating shaft 9 that projects from the thin material hanging arm 5 in the vertical direction. A spring 22 is applied to the rotating shaft 9 to force the holding piece 21 into elastic contact with the arm 5, and the spring 22 is applied to the arm 5 in parallel with the rotating shaft 9, and the thin material of the extension piece 19 of the material presser 15 is A thin goods packaging characterized by being provided with a stopper rod 7 which is held down by the other protruding rod 18 of the base 16 of the material presser 15 as it rotates in a direction intersecting the material hanging arm 5, and is projected and latched again as it passes. This relates to material hanging.

A preferred embodiment of the invention is described in the following section.

(Example) Figures 1 to 5 show examples of the present invention, where Figure 1 is a perspective view, Figure 2 is a partial vertical side view, Figure 3 is a perspective view of the main part, and Figure 4 is a perspective view of the present invention. The same plan view and FIG. 5 are partially cutaway side views.

FIG. 1 shows a case 1 in which a packaging material hanger arm 5 of the present invention is installed inside, and several support pieces 3 are projected forward at intervals from a support rod 2 attached to the rear side, and each support piece is 3, as shown in FIG. 2, a material hanging arm 5 having a vertically long elliptical cross section is fitted so that it can be freely stored and fixed in a free position on the support piece 3 by a set screw screwed into the arm. It is set as.

A decorative plate 5a is fixed to the front end surface of the material hanging arm 5, and a stopper rod 7 having a push button 8 with a rounded upper end on the rear side thereof is fitted so as to be freely movable up and down, and a rotating shaft 9 is rotated on the rear side thereof. Fit freely.

The stopper rod 7 has a washer 10 and an E-ring 11 fitted into the downwardly protruding portion of the arm 5, and a spring 12 is applied to the lower surface of the push button 8 inside the arm 5.
, and part of the push button 8 is protruded. A washer 13 and an E-ring 14 are fitted onto the rotary shaft 9 at a portion that projects downward from the arm 5, and a material presser 15 is attached to the upwardly projecting portion.

The material presser 15 has a base 16 bent into an inverted U shape.
, an extension piece 19 bent from one protruding rod 17 of the base 16 almost parallel to the arm 4 as shown in FIG. 4, and a presser piece bent from the extension piece 19 at right angles in the direction of the arm 5. It consists of a small mounting rod 20 and a vertically long presser piece 21 that contacts one side of the arm 5, and the extension piece 19 may be bent downward into a U shape as shown by the dashed line in FIG. Inverted U-shaped base 1
6 is attached to the upper end of the rotating shaft 9 as shown in FIGS. 3 and 4, and the upper end of the torsion spring 22, which is fitted slightly loosely to the rotating shaft 9, is hung on the other protruding rod 18, and the other end is attached to the arm. When the material presser foot 15 is rotated against the elasticity of the spring 22 as shown by the two-dot chain line in FIG. Lower the abutting stopper lever 7 against the launch spring 12, and after passing the protruding rod 18 backward, push the push button 8 and press the protruding rod 18.
stop.

(Function) In the present invention, the material presser 15 is connected to the rotating shaft 9 together with the spring 2.
2 presses the presser piece 21 against the side surface of the material hanging arm 5, so that one part of the side surface of the thin packaging material 31 hung on the material hanging arm 5 as shown in FIG. Even if one or several sheets of the material 31 are pressed and pulled in the arrow x or y direction, only one or several sheets will be separated, and the remaining ones will stick and be separated or move. I don't do it.

Also, when replenishing or replacing the remaining thin packaging material 31, if the extension piece 19, etc. is rotated as shown by the two-dot chain line in FIG. 4 against the elasticity of the spring 22, the other protruding rod 18 presses the head of the push button 8, sinks the stopper rod 7 against the elastic force and passes, and as it passes, the stopper rod 7 rises again together with the push button 8, hooks the protruding rod 18, and holds the side of the material hanging arm 5. It dawns. After the arm 5 has been hooked onto the thin packaging material 31, press the extension piece 19, etc.
The push button 8 and the stopper rod 7 sink, and the presser piece 21 of the material presser 15 is sandwiched between the thin packaging material 31 and the material hanging arm 5 by the elasticity of the spring 22. When the material presser foot 15 is rotated as shown by the two-dot chain line in FIG. 4, the other protruding rod 18 comes into contact with the decorative plate 5a as shown in the figure, and if the structure is such that the protruding rod 18 finishes passing over the push button 8 at that time, the presser foot 15 can be reliably prevented from rotating excessively.

(Effects) The present invention has the above-described structure and operation, and the presser piece 21 of one material presser 15 is pressed against the side surface of the material hanging arm 5, and the material presser 15 is pressed against the spring 22.
The holding piece 21 is rotated against the elastic force of the material hanging arm 5 to rotate it laterally from the side surface of the material hanging arm 5, and the other protruding rod 18 is locked by the stopper rod 7 so that it does not return. The packaging material 31 can be hung onto the material hanging arm 5 without being bothered by the material presser 15. Further, the stopper rod 7 is automatically held down as the above-mentioned protruding rod 18 rotates, and as the rod 18 passes, the stopper rod 7 is pushed out by elasticity, so that when the material presser 15 is reversibly rotated in two directions, However, the automatic action that is performed without having to touch the stopper rod 7 makes it easy to use.
