Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a box body take-out device for taking out a box body filled with rod-shaped small items from a shape-retaining tray whose front and top sides are open.

[Conventional technology]

For example, when shipping a rod-shaped cigarette filter plug that is cut to a predetermined size and used,
A cardboard box body in which one side plate is swingable around the edge of the bottom plate is placed with its opening facing forward and with the swingable side plate positioned upward. At the same time as setting the box in an automatic filling device, the plugs (hereinafter referred to as small rod-shaped objects) are sequentially filled from the lower side plate of the box main body while lowering the box, and after filling is completed, check the filling state of the small rod-shaped objects. After checking and replenishing the box, the lid is attached to the box body, and the box (in other words, the inner box) is
A method is adopted in which a plurality of items are stored in an outer box and transported.

The reason why one of the side plates of the box body is swingable with respect to the bottom plate is to make it possible to easily and automatically fill the rod-shaped small items up to the upper side plate.

By the way, the above-mentioned cardboard box body is generally used repeatedly as a shipping box, but there is a considerable difference in the degree of shape retention between the new box body and the old box body, and the above-mentioned rocking is inevitable. The left and right side plates located on both sides of the free side plate tend to expand freely, making it difficult to automatically fill a predetermined amount of bar-shaped small items. The main body is housed in a shape-retaining tray that is open at the front and top.

[The problem that the idea aims to solve]

Therefore, it is necessary to take out the box body from the shape-retaining tray in order to cover the box body after checking the filling state of the rod-shaped small items and replenishing the box body.

Removal of the box main body was carried out by hand by holding the left and right side panels of the box main body and pulling it out, which was a very inefficient process.

In particular, the left and right side plates are easy to bend and often tend to expand left and right, and for this reason,
There was room for improvement in that the posture of the stored small items was disturbed, the lid was difficult to attach to the box body, and the work was time-consuming.

The present invention was devised in view of the above circumstances, and it is an object of the present invention to provide a box body retrieval device that eliminates the above-mentioned inconveniences at once.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a device for taking out a box body from a shape-retaining tray. It is also a device for taking out a cardboard box body filled with rod-shaped small items, and transports the shape-retaining tray containing the box body to a work place for checking the filling state, attaching a lid, etc. A guide that is tilted backward is installed on the terminal end side of the conveyor, and a tray holder having a substantially L-shape in side view that holds the shape-retaining tray fed by the conveyor in a tilted posture that is tilted backward is installed at the end of the conveyor. It is provided along the guide and by a lifting drive mechanism so as to be freely raised and lowered between a tray inheritance level for taking over the shape-retaining tray from the conveyor and an intermediate level above it, and above the intermediate level is a box body. A bottom plate supporting member tilting backward to support the bottom plate of the box body and a lower side plate supporting member movable in and out supporting the lower side plate of the box body are provided,
The tray holder is equipped with a tray suitable for checking the filling state from the intermediate level by passing only the box body inside the shape-retaining tray along the bottom plate supporting member through the bottom part of the shape-retaining tray, and attaching the lid. It is characterized by the provision of a mechanism for pushing up the box body to the working level.

[Effect]

According to the above configuration, when the shape-retaining tray containing the box body is sent to the tray holder by the conveyor, the tray holder is lifted to the intermediate level along the guide inclined backward by the lifting drive mechanism. It will be done.

When the tray holder is lifted to the intermediate level, the box body inside the shape-retaining tray is lifted up to the work level along the bottom plate support member tilted backward by the box body lifting mechanism that penetrates the bottom part of the tray holder. It will be lifted and removed from the shape-retaining tray.
