Description

  The present invention relates to a packaging container used for storage, transportation, etc. of film rolls.

  When storing and transporting a film roll formed by winding a long film around a winding core, a packaging container is used to protect the film. When a packaging container is used, a film roll having a pair of supports attached to both ends of a winding core is housed in the packaging container, and the film roll is supported by the pair of supports in the packaging container. The support is attached to the film roll by inserting the protrusion protruding from the plate into the hollow portion at the end of the winding core. In a packaging container, a film roll is housed in a state in which a pair of supports is held between a pair of side plates (see, for example, Patent Document 1). By thus storing the film roll in the packaging container, it is possible to protect the film from vibration, shock, foreign matter, etc. and prevent deterioration of the film quality.

Patent No. 5099149

  When the film roll with the pair of supports attached thereto is taken in and out of the packaging container, it is carried out mechanically by a film roll conveying device or the like, or manually by a person. For example, in the case of using a transfer device, each arm of the transfer device is inserted into a support hole that is opened on the side plate side of the protrusion of each support, and the film roll is gripped by a pair of arms to take in and out. .

  In order to insert/remove such an arm into/from the support hole of the support, a movable space for the arm is required between the plate of the support and the side plate of the packaging container. Generally, a spacer is interposed between the plate of the support and the side plate of the packaging container, and the movable space of the arm is secured by the spacer. When such a spacer is provided in the packaging container, the packaging container needs to be made larger as the spacer thickness becomes thicker. Therefore, the spacer should be thin. However, if the spacer is made thin, the movable space of the arm becomes narrow, the workability of inserting/removing the arm into/from the support hole is deteriorated, and high positional accuracy with respect to the arm is also required.

  Therefore, in this technical field, there is a demand for a packaging container that can improve the workability of loading and unloading the film roll from the packaging container.

  The packaging container according to the present invention is a packaging container that stores a film roll formed by winding a long film around a winding core with a pair of supports attached to both ends of the winding core, and a bottom plate. And a pair of first side plates facing each other in the axial direction of the film roll, and a pair of second side plates respectively connected to the one first side plate and the other first side plate and connected to the bottom plate, Has a plate portion, a protruding portion protruding from the plate portion, and a support hole portion opened on the side of the first side plate of the protruding portion, and the protruding portion is inserted into the hollow portion at the end of the winding core. Is attached to the film roll in this state, and the first side plate is formed with a notch portion corresponding to the position of the support hole portion of the support member and cut out according to the direction in which the film roll is taken in and out.

  This packaging container is composed at least of a bottom plate, a pair of first side plates, and a pair of second side plates. In the packaging container, the film roll to which the pair of supports is attached is housed while the pair of supports is held between the pair of first side plates. Since the support has a support hole opened on the side of the first side plate of the protrusion protruding from the plate, the support can be gripped by inserting the arm of the transfer device or the like into the support hole. .. The first side plate is formed with a notch corresponding to the position of the support hole portion of the support. The notch is notched according to the direction in which the film roll with the pair of supports attached thereto is taken in and out. Therefore, when putting the film roll into the packaging container, in the notched portion of the cutout portion of the first side plate, the arm of the carrier device holding the support body or the like from the outside of the packaging container to the support body as the bottom plate. It can be moved until it is placed. Further, when the film roll is taken out from the packaging container, the arm or the like of the transport device holding the support can be moved to the outside of the packaging container in the notched portion of the cutout portion of the first side plate. .. Furthermore, since the side of the first side plate is open, when the film roll is taken in and out of the packaging container, when the arm of the carrier device is inserted/removed into/from the support hole portion of the support, the transfer is performed. The arm of the device can be freely moved to the side of the first side plate. Thus, in this packaging container, the workability of loading and unloading the film roll from the packaging container can be improved by providing the cutout portion in the first side plate in accordance with the direction in which the film roll is loaded and unloaded. In addition, since a spacer for inserting/removing the arm of the carrier device into/from the support hole portion is not required in the packaging container, the size of the packaging container does not become larger than necessary.

  The packaging container of one embodiment includes a lid that covers an upper opening formed by the bottom plate, the pair of first side plates, and the pair of second side plates. By providing the packaging container with the lid, the lid covers the upper part of the packaging container, and thus the protection of the packaging container against the film roll can be improved. Also, a plurality of packaging containers can be stacked.

  The packaging container according to one embodiment includes a pair of outer plates respectively arranged outside the pair of first side plates, and a joint portion for detachably joining the first side plate and the outer plate. By providing the outside plate on the outside of the first side plate, the cutout portion of the first side plate can be covered with the outside plate, the protection of the packaging container against the film roll can be improved, and the strength of the packaging container can be improved. Further, by providing a joining portion capable of detachably joining the first side plate and the outer side plate, when the film roll is stored in the packaging container, the first side plate and the outer side plate are joined and The notch can be covered with an outer plate, and when the film roll is taken in and out of the packaging container, the outer plate can be separated from the first side plate to open the side of the first side plate. In the case where the packaging container has a lid and an outer plate, light can be prevented from entering the packaging container, and thus a photosensitive film roll can be applied as the film roll.

  In the packaging container of one embodiment, the bottom plate and the outer plate are connected, and the connected portion can be bent. With such a configuration, the outer plate can be bent with respect to the bottom plate and the outer plate can be joined to the first side plate. Furthermore, since the outer plate is connected to the bottom plate, the strength of the packaging container can be improved.

  In the packaging container of one embodiment, the film roll is taken in and out in the vertical direction, and the notch is notched by opening the upper side of the first side plate. When the film roll is taken in and out of the packaging container, it is best to move the film roll in the vertical direction.

  In the packaging container of one embodiment, the width of the notch is wider than the width of the support hole of the support. By making the width of the cutout portion of the first side plate wider than the support body hole portion of the support body, it is possible to smoothly move the arm and the like of the transfer device and insert/remove the support body into/from the support body hole portion of the support body. Therefore, the workability of loading and unloading the film roll from the packaging container can be further improved.
