Abstract

PROBLEM TO BE SOLVED: To automatically package a pachinko machine to improve packaging capacity by inverting a two-folded sheet in a developed form, carrying the pachinko machine into an obtained storage space, applying a longitudinal seal on a back of the sheet to provide a bag, and sealing an upper end opening of the bag to complete packaging. SOLUTION: A two-folded sheet (s) fed from a sheet roll (r) by a feed mechanism is slid inside from the outside of a guide 18 of a sheet folding guide 16 to be inverted in a developed form, and its bottom is passed below a carrying part 27 of a first conveyer 20. A longitudinal seal is applied by a longitudinal sealer 30 to the sheet (s), the middle of a welded part is cut, and an upper end of the cut sheet (s) is held by a sheet holder. While a pachinko machine (p) is carried into a storage space of the sheet (s) in this state, the machine (p) is fed onto a second conveyer 50. After the sheet (s) on a back position of the machine (p) is longitudinally sealed, an upper end opening of a bag (a) is welded by a bag mouth device 75 to complete the packaging.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging machine for automatically packaging pachinko machines one by one.

[0002]

2. Description of the Related Art A conventional pachinko machine is generally packed in a box without packaging and shipped from a factory. In addition, dust may adhere to the pachinko machine while it is being stored in a warehouse, etc., or if it is left unpacked, there is a risk that the control device etc. may be intentionally modified to increase the payout rate. Some manufacturers also packaged pachinko machines and packed them in boxes.

[0003]

When packaging a conventional pachinko machine, use a special bag prepared in advance,
A method has been adopted in which the bag is put on each pachinko machine and then the bag mouth is closed. However, in such a packaging method, since the pachinko machine is large, it is difficult to consistently automate the process from supplying the bag to sealing the bag mouth,
The packaging ability was low.

[0004] It is an object of the present invention to provide an automatic packaging machine for a pachinko machine in which a series of steps from supply of a sheet forming a bag to packaging are completely automated, and the packaging ability is improved.

[0005]

In order to achieve the above object, the present invention provides a sheet roll in which a sheet folded in two in a longitudinal direction is provided on a machine frame so as to be freely rotatable in a horizontal direction. A sheet feeding mechanism that timely feeds the sheet fed out from the pair of guide rollers to a pair of guide rollers via a dancing roller, and a bent portion is disposed near one end of the guide roller, and guide portions on both sides are disposed above the other end of the guide roller. A substantially U-shaped sheet folding guide provided in an inclined manner, and a cantilevered conveying section for carrying a pachinko machine as a packaged object in a laterally standing posture from the bent portion side at a central position in the sheet folding guide. A first conveyor device provided to support the sheet, and the sheet passing through the guide roller is slid inward from the outside of the guide portion of the sheet folding guide so as to be developed. The sheet feeding device is provided so that the bottom is passed under the conveyance section and the side edges thereof are directed upward, and the sheet is fed from the sheet feeding device, and a longitudinal portion of the sheet fed from the sheet feeding device is welded. A pair of seal bars are provided so as to be openable and closable, and a heater wire for vertically cutting the middle of the welded portion is provided on the inner surface of one of the seal bars. Gripping device that can open and close a holding piece that grips the upper end of a sheet that has been subjected to a sheet, and a sheet that has a vertical seal applied only to one side at the tip, or a continuous sheet that has a vertical seal applied to both front and rear sides. Conveyor device for intermittently transporting a pachinko machine wrapped by a bag formed separately from a sheet-like sheet, and a bag containing the pachinko machine on a transport unit of the second conveyor device A holding piece for gripping the upper end portion is provided so as to be openable and closable, and the holding piece is vertically movable so that the bag is loosely held in the longitudinal direction. A bag mouth sealing device provided with a pair of seal bars that can open and close a pair of seal bars for welding the opening portion of the bag, wherein the pachinko machines continuously fed by the first conveyor device are packaged one by one. It is characterized by the following.

[0006]

The folded sheet fed from the sheet roll to the guide roller side by the sheet feeding mechanism slides inward from the outside of the guide portion of the sheet folding guide, and is flipped in a developed state. Passes below the transport section of the first conveyor device, and is fed out with both side edges thereof set to be upward. The sheet fed from the sheet supply device is vertically sealed by a vertical sealing device, and the middle of the welded portion is cut in the vertical direction. At this time, the upper end of the cut sheet is gripped by the holding piece of the sheet gripping device, and in this state, the pachinko machine in the upright posture in the horizontal direction is conveyed into the sheet by the first conveyor device. Then, the holding piece of the sheet gripping device opens,
The first conveyor device and the second conveyor device operate synchronously to move the pachinko machine placed in the sheet by a predetermined distance and stop it on the transport section of the second conveyor device. Therefore, at a position corresponding to the rear side (the loading side) of the pachinko machine, a second vertical seal is applied to the sheet by the vertical seal device, and the middle of the welded portion of the vertical seal is cut in the vertical direction. Thus, the pachinko machine is in a state of being wrapped in one bag which is formed with a vertical seal on both front and rear sides and separated from a subsequent sheet.

Next, when the pachinko machine housed in the bag is moved to the position of the bag mouth sealing device by the second conveyor device and stopped, the bag is gripped at its upper end by the holding piece of the bag tensioning device. It is held loosely in the vertical direction. In this state, the seal bar of the bag mouth sealing device is closed, and the opening of the bag is welded. Next, the seal bar is opened, and the pachinko machine completely sealed and packaged is carried out by the second conveyor device. By repeatedly performing the above-described series of operations, the pachinko machines continuously fed by the first conveyor device are wrapped one by one, and sent out to the outside by the second conveyor device.

[0008] This automatic packaging machine for a pachinko machine can completely automate a series of steps from supply of a sheet forming a bag to packaging of a pachinko machine, and can significantly improve the packaging ability.
