[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a separating device for separating a required number of sheet-like objects from a laminate formed by stacking sheet-like objects and carrying them out to the next step.

[0002]

In recent years, many canned beverage products and other products manufactured in manufacturing factories and the like are shipped in a prescribed number of packages packed in carton boxes.

The carton box used for packing this product is supplied to a boxing machine called a wrap round caser in an unfolded state (hereinafter, this unfolded state is referred to as a carton sheet), and this wrap round In the caser, the products supplied from the product supply unit are assembled while enclosing a specified number of products, and the products are packed.

The carton sheets assembled in the carton box as described above are usually delivered from the paper manufacturer to the packaging department of the factory in the form of a stack of several hundred sheets. Therefore, the delivered carton sheet cannot be supplied to the wrap round caser in the laminated state.

Therefore, the supply of the carton sheets to the wrap round caser is carried out while a separating device is installed in the preceding step of the wrap round caser and the carton sheets are separated from the laminate by the required number of sheets. Is common.

FIGS. 13 and 14 show a conventional method for separating the carton sheets supplied to the wrap round caser from the above-mentioned laminated body by a required number of sheets, which are installed in the preceding step of the wrap round caser. 1 shows a separating device.

In FIGS. 13 and 14, a laminate A of carton sheets that has been delivered and unpacked.
Is placed on an elevating table 1 which is attached to a machine frame K of a separating device so as to be elevatable.

In this state, when packing of products in a carton box is started in a wrap round caser (not shown) installed in the subsequent step of the separating device, the lifting table 1 of the separating device is lifted to raise the stack A. Is being lifted. When the sheet surface detection sensor 2 attached to the upper part of the machine frame K detects that the upper surface of the stack A has been lifted to a predetermined height, the lifting of the lifting table 1 is stopped.

At the stop position of the lifting table 1, the rear surface of the stack A (left side in FIG. 14) is lowered from the top surface of the stack A by the thickness of the required number of carton sheets to be separated. The separation needle 3 attached to the machine frame K so as to be capable of advancing and retracting in the horizontal direction is opposed to the position, and after the lifting table 1 is stopped, the separation needle 3 is advanced by a drive mechanism (not shown), and its tip end is laminated. It is inserted between the stacked carton sheets of body A.

As a result, a required number of carton sheets to be separated are provided above the separating needle 3 inserted in the laminated body A (hereinafter, the carton sheet is located above the separating needle 3 and is separated from the laminated body A). The required number of carton sheets to be separated is referred to as a separated carton sheet A ').

After that, the elevating table 1 is lowered, whereby the rear end portion (left end portion in FIG. 14) of the separation carton sheet A'is left over from the remaining portion of the laminated body A located below the separation needle 3. It is relatively lifted from the top of the carton sheet. At this time, the lifting table 1 that is lowered
Is stopped at a position where the uppermost surface of the remaining carton sheets of the laminated body A located below the separation needle 3 is at substantially the same height as the conveyance surface of the conveyor V arranged adjacent to the separation device. .

After the elevating table 1 is lowered, the sheet pressing plate 4 attached to the machine frame K at the rear position of the stack A is advanced by a drive mechanism (not shown) to be located below the separating needle 3. The remaining carton sheet of the body A is brought into contact with the uppermost surface of the rear end portion of the carton sheet, and thus the remaining carton sheet of the stack A is held.

Thereafter, the feeder 5 slidably attached to the upper portion of the machine frame K in the horizontal direction is advanced by a drive mechanism (not shown) in a direction approaching the separated carton sheet A '(leftward in FIG. 14). , The rear end of the separation carton seat A ′ lifted by the separation needle 3. Then, the separated carton sheet A'has a rear end portion formed on the lower end portion of the feeder 5 by a hook portion 5 '.
In the state of being carried by, as the feeder 5 advances, it slides on the upper surface of the remaining carton sheet of the stack A and is pushed out in the direction of the conveyor V.

When the separated carton sheet A'is positioned on the conveyor V, the feeder 5 is retracted and the engagement state with the separated carton sheet A'is released. The separated carton sheet A ′ thus transferred onto the conveyor V
Is conveyed by the conveyor V and supplied to the lap round caser in operation.

By repeating the above operation as described above, the separated carton sheet A'from the laminated body A is obtained.
Are separated and are sequentially supplied to the lap round caser.

However, in the conventional carton sheet separating apparatus, as can be seen from FIG. 14, when the separated carton sheet A'is separated from the stack A, the rear end portion thereof is lifted by the feeder 5 and inclined. Since it is pushed out in this state, the leading end of the separated carton sheet A ′ moves in the direction of the conveyor V while sliding on the upper surface of the remaining carton sheets of the stack A.

Therefore, when the carton sheet remaining in the laminated body A is warped or the smoothness of the upper surface thereof is not ensured, the leading end of the separated carton sheet A'is separated during the separation. Along with the movement, the remaining carton sheet of the stack A may be caught in the warped portion, and the remaining carton sheet of the stack A may be dragged.

When the separated carton sheet A ′ thus separated is caught on the carton sheet remaining in the laminate A and the remaining carton sheet is dragged, the separated carton sheet A ′ is normally transferred to the conveyor V. Therefore, it becomes impossible to carry out automatic feeding, and there arises a problem that the separating device and further the entire packaging line must be stopped.

Such a problem is not limited to the case of the carton sheet separating apparatus for assembling the carton box as described above, and other kinds of sheet-like materials are separated from the laminate and supplied to the subsequent process. The same applies to such a separating device.

The present invention has been made in order to solve the problems of the above-mentioned conventional sheet-like material separating device.

That is, according to the present invention, when a predetermined number of laminated sheet-like materials are separated from the laminated body and supplied to the subsequent process, the separated sheet-like materials can be carried out smoothly. It is an object of the present invention to provide a sheet-shaped material separating apparatus that does not stop the separating apparatus itself or the entire process line including the separating apparatus.

[0022]

In order to achieve the above object, a sheet-shaped article separating apparatus according to a first aspect of the present invention is a sheet-shaped article separating apparatus, which is formed by stacking sheet-like articles from the side of the laminate. Insert a plug-in member between the sheet-like materials to form a gap between one ends of the sheet-like material, and insert a carry-out member into this gap to position the sheet-like material located above the gap below By carrying out from above the sheet material,
In a sheet-shaped material separating device for separating a required number of sheet-shaped materials from a laminated body, a stack is formed at a position facing a gap formed between one ends of the sheet-shaped material of the laminated body by the insertion member. It is slidably arranged in the direction of approaching and separating from the sheet, and enters the gap by being slid in the direction of approaching the laminated body, and lifts the other end of the sheet-like article located above the gap. It is characterized in that it is provided with a sheet support member that supports the sheet-like material located below it in a state of being separated therefrom.

In the sheet-shaped product separating apparatus according to the first aspect of the present invention, the stack formed by stacking the sheet-shaped products is positioned at a predetermined position to separate the sheet-shaped products from the stack, and After the insertion member is inserted between the sheet-like materials from the side of the laminate to form a gap between the one ends of the sheet-like materials, the sheet support member is slid in the direction of approaching the laminate. The sheet is inserted into a gap formed between one ends of the sheet.

The sheet supporting member is further slidably brought into contact with the lower surface of the sheet-like article located above the gap in the gap and slid to the other end side of the sheet-like article so that the sheet located above the gap. By lifting up the sheet-like object, the other end of this sheet-like object is separated from the sheet-like object located below the gap, and the other end of this sheet-like object is lifted and stopped. .

After that, the conveying member inserted into the gap on the other end side of the sheet-like article lifts the sheet-like article located above the gap and the other end is lifted by the sheet supporting member. The sheet-like material is carried out from above the sheet-like material located below the gap while being supported by the sheet-like material.

As described above, according to the sheet-like material separating apparatus of the first aspect of the present invention, when the sheet-like material is separated from the laminate by a predetermined number and is supplied to the subsequent step, the separated sheets are separated. Since the sheet-like material is carried out from above the remaining sheet-like material in a state where the sheet-like material is completely separated from the remaining sheet-like material in the laminate, the sheet-like material separated at the time of this carry-out is the remaining sheet-like material. There is no risk of dragging the sheet-like material, and the smooth removal of the sheet-like material to be separated requires the separation device itself and the entire process line including this separation device to be stopped due to a trouble caused by the dragging of the sheet-like material. It is possible to prevent a situation from occurring.

In order to achieve the above-mentioned object, in the sheet-shaped article separating apparatus according to the second invention, in addition to the structure of the first invention, the sheet supporting member extends in the horizontal direction and both end portions are laminated. It is characterized in that it is a bar member slidably supported by a pair of guide rails arranged at positions sandwiching the body.

In the sheet-shaped article separating apparatus according to the second aspect of the present invention, the sheet-shaped article is slid along a pair of guide rails arranged at positions where the sheet support member, which is a bar, sandwiches the laminated body. The sheet-like material is introduced into the gap formed between the one end portions of the sheet-like material and lifts the sheet-like material while slidingly contacting the lower surface of the sheet-like material located above the gap.

In order to achieve the above object, in the sheet-shaped article separating apparatus according to the third invention, in addition to the configuration of the second invention, the sheet supporting member is rotatably attached to the sheet supporting member. It is characterized in that the roller member is provided.

In the sheet-shaped product separating apparatus according to the third aspect of the present invention, the sheet support member, which is a bar, enters into the gap formed between the one ends of the sheet-shaped products of the laminated body, and slides. The friction between the sheet supporting member and the sheet-like material is reduced by the roller member rolling along the lower surface of the sheet-like material when slidingly contacting the lower surface of the sheet-like material located above the gap. As a result, the sheet-like material can be smoothly separated.

In order to achieve the above-mentioned object, the sheet-shaped product separating apparatus according to the fourth invention is, in addition to the structure of the first invention, one end of the sheet-shaped product located above the gap. Is further provided with a gripping member which is arranged at a position opposed to the above, and which grips the rear end portion of the sheet-like material located above the gap.

In the sheet-shaped article separating apparatus according to the fourth aspect of the present invention, an inserting member is inserted from the side of the laminated body between the sheet-shaped articles to form a gap between one ends of the sheet-shaped articles. After that, before the sheet support member enters the gap, the gripping member grips the rear end portion of the sheet-like material located above the gap. This prevents the sheet-like material from being dragged by friction with the sheet-supporting member when the sheet-supporting member enters the gap of the sheet-like material.

In order to achieve the above-mentioned object, the sheet-shaped product separating apparatus according to the fifth invention is a carton sheet in which the sheet-shaped product is assembled into a carton box in addition to the configuration of the first invention. It is characterized by that.

The sheet-like material separating apparatus according to the fifth aspect of the invention is installed in a front step of a wrap round caser for assembling carton sheets in a state where the carton box is expanded to pack the products. A predetermined number of carton sheets that can be carried into the wrap round caser are separated from the stacked body in which a large number of sheets are stacked, and are supplied to the wrap round caser installed in the subsequent process.

The operation of the lifting drive mechanism is stopped, and the lifting of the lifting table 12 is stopped.

Here, the sheet surface detection sensor 16 is a carton sheet whose height difference h (see FIG. 3) between the detection position on the upper surface of the laminate A and the mounting position of the separation needle 15 is about to be separated. The detection position is set to be the same as the thickness of the.

Therefore, the separating needle 15 is placed on the lifting table 12 as shown in FIG. 3 when the seat surface detection sensor 16 contacts the upper surface of the laminate A and the lifting table 12 stops. The rear surface of the stack A is opposed to a position lower than the top surface of the stack A by the thickness of the carton sheet to be separated.

After the lifting table 12 is stopped, the separating needle 15 facing the rear surface of the stack A in the above state is projected from the standby position by the operation of the air cylinder, and the carton sheet of the stack A facing the stacking needle is removed. Inserted in between. As a result, a carton sheet having a required thickness (that is, a required number of sheets) to be separated (hereinafter referred to as a separated carton sheet A ′) is positioned above the separating needle 15.

Thereafter, the elevating and lowering drive mechanism is driven in the opposite direction to lower the elevating and lowering table 12, and stops when it is lowered by a predetermined height. At this time, at the stop position of the lifting table 12, the lifting drive mechanism is controlled so that the upper surfaces of the remaining carton sheets of the stack A are positioned below the transport surface of the conveyor V.
