Abstract

<P>PROBLEM TO BE SOLVED: To suppress trouble during the picking as much as possible by reliably executing the picking by a carton picking device, and feeding a carton into a mandrel. <P>SOLUTION: In a carton picking device for feeding a folded carton to a filling device, a plurality of picker suction packings to be driven by a servo mechanism are sucked to the carton to expand the carton in a cylindrical shape, and then, to feed the carton to a mandrel of a next process by a belt to be driven by the servo mechanism. <P>COPYRIGHT: (C)2010,JPO&INPIT

Description

  The present invention relates to a carton picking device that opens a folded carton into a cylindrical shape and feeds it into a device for filling a beverage typified by milk or the like.

  A number of stacked cartons stored in the storage unit are picked one by one from one end by a picking unit, and the cartons are opened and fed into a mandrel unit for sealing the bottom. Conventionally, when picking from the final end on the feeding side by the picking portion, the driving is performed by connecting the main shaft and the cam.

  Also, with this method, a stable stroke cannot be obtained, and picking mistakes may occur. In this case, processing such as stopping the device and removing a carton that has been picked is required each time, resulting in labor and work loss. (Patent Document 1)

  Japanese Patent No. 2654573

  The present invention enables a carton supply device for sending a carton to a filling device in an open state by reliably performing picking by the carton picking device and feeding it to a mandrel, thereby minimizing trouble during picking. Is.

  That is, the carton picking device according to claim 1 is a device for feeding a folded carton to a filling device, wherein a plurality of picker adsorbing packings driven by a servo mechanism are adsorbed to the carton and the carton is expanded into a cylindrical shape. The belt is driven by a servo mechanism and fed to a mandrel in the next process.

  The invention of claim 2 is further characterized in that, among the above inventions, the servo mechanism can control the stroke amount of the picker adsorption packing according to the type of carton.

  According to the carton picking apparatus of the first aspect of the invention, the carton is driven by the servo mechanism and the carton is adsorbed by the picker adsorbing packing, so that a stable picking operation can be performed. In addition, since each part is driven independently by the servo mechanism, the replacement work at the time of mold change by changing the type of carton can be performed much faster than the conventional one.

  According to the invention of claim 2, since finer setting is possible and the stroke amount can be controlled for each carton due to the difference in capacity or the difference in goods, the adsorption of the carton is more stable, and the filling device Trouble at the picking part for feeding into the machine is extremely reduced.

  Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a schematic view of the apparatus, in which a carton 4 is accommodated in a state of being superimposed on a carton storage unit 1. At one end, a carton picking device 2 is provided, which is adsorbed by a picker adsorbing packing 3 provided at the end of the carton picking device 2, holds one end, and the carton 4 is cylindrical. And is driven by a bell and drive to a mandrel portion (not shown in the upper side in the figure) which is a bottom seal portion, which is the first step of the filling device. You may provide the blow apparatus for paper dust removal here as needed.

  The belt 5 to be fed into the mandrel is driven by a servo mechanism, and in order to avoid operation interference with the mandrel, the insertion of the next carton 4 is started after the insertion is completed and the mandrel starts to move. It is controlled. Further, since each part is controlled by an independent servo mechanism, the replacement work becomes easier.

  The stroke amount control by the servo mechanism can be controlled based on the past data according to the type of the carton 4.

  A plurality of cartons filled with 1000 ml of milk were stored in a storage section in a stacked state, and production was performed by an existing method. Production was continued with replenishment of cartons as appropriate. Furthermore, the model was changed and changed to a 500 ml carton, and the same production was performed.

  In any production, there was no trouble during feeding during picking, and filling could be continued. Thereby, the effectiveness of the present invention was confirmed.
