Description

[Detailed description of the invention] The present invention is designed to prevent the winding tube (hereinafter referred to simply as the winding tube), which is wound with bag-making film, from being damaged or misaligned during transportation. This invention relates to a protective side abutment material for the end edge of a winding tube to prevent bag defects and uneven printing.

Conventionally, the winding tube has been transported with protective material in contact with both edges, but after transport, the tube is unpacked on the floor when it is attached to a bag-making machine, printing machine, etc. The protective material is removed, a support shaft is inserted into the center of the winding tube, and large-diameter tubes are hoisted to a certain height using a crane or hoist before being attached to the machine. By the way, although it is protected by protective material during the above operation, that is, during transportation, once it is unpacked, it becomes unprotected, and therefore, it is possible that the work such as inserting the spindle may cause scratches or misalignment. There is a problem.

In view of the above-mentioned problems, the present invention is designed to maintain the packaged condition not only during transportation but also until the final step of installing it on the machine, and to make it possible to unpack and remove the protective material only after it is installed on the machine. The aim is to eliminate this problem.

An example of implementing the present invention will be described below based on the drawings.

Fig. 1 is a perspective view of the protective material according to the present invention, Fig. 2 A, B, C, and D are partial explanatory diagrams showing the embodiment of the breaking line, and Fig. 3 shows the state in which the protective material is removed after being installed on a machine. It is an action explanatory diagram.

Reference numeral 1 denotes a protective side member, which includes a side plate main body 1a made of plywood, hardboard, interleaving paper, etc., a flange body 1b made of hardboard, interleaving paper, etc. with an L-shaped cross section attached to its periphery; Consisting of

Here, the side plate main body 1a has a donut disk shape with a through hole 2 bored in the center, and at least one part of the side plate has a diameter d approximately equal to or slightly larger than the diameter d of the through hole 2. A pair of breaking lines 3a and 3b are provided from the center to the outer periphery. As shown in FIGS. 2A, B, C, D, and E, the fracture lines 3a and 3b have a V-shaped cross section (Figure A), a linear cut (Figure B), and an eight-shaped cut (Figure B). Figure C), reverse eight-shaped cut (Figure D), perforated cut (Figure E)
etc.

In the present invention, as mentioned above, at least one part of the side plate has a dimension approximately the same width as the diameter of the through hole 2 or slightly larger, and a fracture line 3 extending from the center to the outer periphery.
A and 3b are provided, and during transportation, the protective side members 1 are brought into contact with both end edges of the winding tube 4, as in the past, and packed. However, in the present invention, after transportation is completed, the support shaft 5 is inserted into the center of the winding tube 4 without unpacking, that is, in that state, and both ends of the support shaft 5 are secured using a hoist, crane, etc. The package is then unpacked after being hoisted to a certain height by the mounting frame (not shown) of the intended packaging machine or printing machine. Hold the partition plate 6 surrounded by the break lines 3a and 3b formed on one side and strongly pull it toward you (in the direction of arrow f). As a result, the partition plate 6 is removed from the surface of the main body 1,
The rest can be removed as a whole by holding the upper part of the side plate including the flange body 1b in your hand and pulling it up above the support shaft 5.

As described above, the present invention allows the side surfaces of the protective material to be partially broken and removed.
It is also possible to completely prevent damage or misalignment caused by conventional unpacking and installation into a machine.
