Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF APPLICATION OF THE INDUSTRIAL INDUSTRIAL APPLICATION 1 The undeveloped industry relates to a method for continuously and automatically boxing a predetermined number of cylindrical bodies, such as rolls of film.

[Prior Art] Synthetic resin films used for commercial purposes such as packages are usually wound around a roll core and provided as a roll-shaped film. Such a roll-shaped film is, for example, 6
It is packed into a box that can hold 10 books, wrapped, and transported to the customer.

This kind of boxing is carried out by automatic boxing machines, but in conventional equipment, the cylinders are fed into an inclined plate that guides them, and the stoppers are successively protruded and depressed to move the cylinders downward one by one. After rolling and dropping a predetermined number of them onto the receiving member placed on the lower edge of the inclined guide plate, the aligned pieces are pushed out in the axial direction and put into the box to be stored. ing.

However, in this conventional method, the cylindrical bodies are fed out one by one by the stopper in an extremely short period of time, and the cylindrical bodies falling from the lower end edge of the guide plate are fed out by the receiving member into a predetermined plurality of cylindrical bodies. Since the dimensions are set to accommodate the body, the first one will bounce inside the receiving member.

Because the products were not allowed to remain in a normal state, the sensors set at specific locations were misrepresented, resulting in the inconvenience of being packaged with an insufficient number of products in the box. . Therefore, such inconveniences and defects had to be covered and resolved manually.

[Problems to be Solved by the Invention] Therefore, an object of the present invention is to effectively overcome the drawbacks of the conventional automatic cylindrical box packing machine and to be able to pack a predetermined number of cylindrical bodies without requiring one person. The purpose is to provide a method for automatically packing boxes smoothly and stably.

[Means for Solving the Problems] The present inventors have repeatedly conducted various trial production studies on modified methods for achieving the above-mentioned [Objective I], and as a result, have developed a method that is extremely desirable for practical use.

That is, in the present invention, the cylindrical body to be packed is placed on the inclined guide plate.
The downward rolling of the cylindrical body is temporarily stopped by a first stopper retractably attached to an appropriate location on the chain plate, and then a predetermined number of the cylindrical bodies are moved to the lower part of the guide plate. After feeding into a second stopper attached to the side so as to be freely retractable, the predetermined number of cylindrical bodies are allowed to naturally rotate and fall.

The cylindrical bodies are arranged on the bottom surface of a receiving member arranged at the lower edge of the "A guide plate and are dimensioned to receive a predetermined number of cylindrical bodies, and the predetermined number of cylindrical bodies aligned are collectively used for cylindrical body storage. To provide an automatic box packing method for cylindrical bodies characterized by pushing them into boxes.

[Example] Hereinafter, the method of the present invention will be explained in more detail with reference to the accompanying drawings.
Do I+.

FIG. 1 is a schematic side view of a barrel explaining the situation in which three cylindrical bodies are packed into boxes.

A roll 1 of a vinyl chloride resin transparent film for packaging is continuously fed into an inclined guide plate 2 from above. The fed cylindrical rolls 1, 1, fist, are dammed and pooled by a first stopper 3 disposed at an appropriate location on the lower edge of the chain plate 2. The stopper 3 is usually composed of a plate-like body that can be retracted through a gap formed in the width direction of the chain plate 2. Further on the lower end side of this plate 2, a similar second stopper 4 is attached at a position corresponding to the number of rolls in a boxing unit of three. The trees are once pooled together. When the second stopper 4 is depressed, the pooled three-wood rolls simultaneously roll down on the guide plate 2 and are passed from the lower edge of the chain plate 2 to the boxing receiver. It falls into the member 5. This fall occurs because the dimensions of the receiving member are set to accept three rolls, so the receiving member 5
There is no such thing as jumping and jumping on your own and settling in an arbitrary direction, but the rolls are 1 r, 1 r, and 1 lower [
This is convenient because it is pushed from the rear and flows in an orderly manner as a whole, and is housed in the receiving member 5 in a predetermined parallel state. In this way, the three rolls moat parallel to the bottom surface of the receiving member are 1, for example, a piston! , FJJ (not shown), it is possible to extrude them all together from one side in the direction of the roll axis and store them in a packaging box (not shown) between the sides [1]. The appearance and retraction of these first and second stoppers, the packing of boxes by piston movement, etc. can be done by installing sensors, such as phototubes, limit switches, or load sensor caps, at appropriate locations to detect the status and number of each. By using the natural rolling descent of the cylindrical body, each operation can be started and stopped quickly and accurately, and the cylindrical bodies can be sequentially fed and packed into boxes.

[Effects of the Invention] According to the method of the present invention, a desired number of cylindrical bodies can be smoothly, rapidly, and stably boxed and packaged in one-by-one motion without requiring any human labor.
