Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for taking out articles in a carton from a carton (cardboard box) after freezing the surimi used in the processing of marine products and foods and packing the articles such as blocks and chocolate, butter and cheese in a carton (cardboard box). Is.
[0002]
[Problems to be solved by the invention]
Conventionally, an article packed in a carton is manually taken out from the carton. However, since the carton is generally packed with about 20 kg of articles, it is manually moved or reversed. Then, it is hard work to cut the carton and take out the goods, which causes back pain and muscle pain. For this reason, it is impossible to work continuously for a long time, and it has been difficult to continuously process the taken-out article in the next process. In particular, the entire process has not yet been automated despite the fact that it has been automated in most of the processing processes for fishery paste products.
[0003]
Therefore, an apparatus for taking out the articles in the carton has been devised, but in the conventional take-out apparatus, three sides of one side of the carton are cut and the opposite side is cut into a circle, and the carton is pushed out from the circular hole with an extrusion pusher. The contents are taken out from. (For example, Japanese Patent Publication No. 55-220944)
[0004]
However, in such a method, the cut pieces of the carton cut into a circle are scattered with the object that falls on the spot at the same time as the cutting, the object that is pushed out by the extrusion pusher and falls to the opposite side, the object that remains in the carton, etc. Removing the cut pieces from the device is a daunting task. Also, if the surface of the pusher side of the carton is cut into a circle, even if you try to fold and organize the carton after removing the contents, it is difficult to fold because it is not creased. There was a problem that it took time because it was necessary.
[0005]
In order to solve the above-mentioned problems, the present invention removes the article from the carton by cutting out three sides and the periphery of the two opposite sides of the carton on the conveyor, and extruding the article in the carton from the box to empty it. An object of the present invention is to provide an apparatus which is arranged in a carton so that the cut pieces are left in a folded state and transported.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the carton peeling device for a boxed article according to the present invention is provided with a carry-in conveyor for conveying a rectangular parallelepiped carton packed with the article, and is connected to the carry-in conveyor so as to face the front and rear surfaces of the rectangular parallelepiped carton. A vertical cutting machine that cuts (cuts) in the vertical (vertical) direction is provided in the vicinity of the left and right sides (ends) of the two surfaces, and the front surface of the carton is in the middle of the path along which the carton moves laterally from the vertical cutting machine. A horizontal cutting machine for cutting in the vicinity of the upper and lower sides of the lower side and the rear surface was provided, and a separator for taking out the articles in the carton was provided in succession to the horizontal cutting machine.
[0007]
The separator is provided with an extrusion member that pushes an article in the carton from the rear surface and takes it out from the front surface of the carton, and a cut piece on the rear surface of the carton is adsorbed to and removed from the extrusion plate attached to the front surface of the extrusion member and left in the carton. An adsorber was provided. It consists of a conveyor for carrying out articles separated adjacent to the separator and a carton removing machine for discharging empty cartons.
[0008]
From the above configuration, the carton packed with articles moving on the conveyor is temporarily stopped and cuts are made in the vicinity of the left and right sides of the front and rear surfaces of the carton, and then the upper side or the lower side of the front side of the carton as the carton moves A cut is made in the vicinity of the upper and lower sides of the rear surface of the carton. After that, the article is pushed out from the rear surface of the carton by the extruding member, and at the same time, the cut piece of the carton is adsorbed by the suction disk, and the cut piece is detached from the adsorbing board in the carton when the extruding member is turned back (retracted). In addition, the empty carton from which the article has been taken out from the carton is removed from the separator by a carton remover, and the empty carton in which the cut pieces remain is folded at the ridgeline, stacked and transported.

Referring to FIG. 1, the carton peeling device for a boxed article of the present invention will be described. The cutting process of a carton 1 packed with a surrogate freezing block 2 which is one of the articles and the separation process of the surrogate freezing block 2 and the carton 1 are illustrated. The carton 1 is sent from (A) to (B), and after the carton 1 is positioned in (B), the carton 1 is fixed and fixed, and the vicinity of the left and right sides (ends) of the front and rear surfaces of the carton 1 is vertical. Make a cut at a depth about the thickness of carton 1 (corrugated cardboard). In addition, since the size of the carton 1 is not constant and varies, the carton 1 is positioned according to the size, and the entering and exiting of the cutter is adjusted.
[0011]
In (C), while moving the carton 1 in the horizontal direction (right direction), horizontal cuts are made in the vicinity of the upper and lower sides of the rear surface of the carton 1 and in the vicinity of the lower side of the front surface. The front surface may have a single horizontal cut at any position. In (D), since the front and rear surfaces of the carton 1 are cut as shown in the figure, when the carton 1 is pushed from the rear surface, the surging refrigeration block 2 in the carton 1 is extruded, and the front surface of the carton 1 is The open-fried frozen block 2 is taken out of the carton 1. The empty carton 1 is moved to another location.
[0012]
As shown in FIG. 2, the carton peeling apparatus for carton goods according to the present invention is provided with a carton carry-in conveyor comprising a carton carry-in belt conveyor 3 and a roller conveyor 4 for forcibly feeding the carton 1 into the machine. A positioning member 5 is provided so as to stop at the combined position. A longitudinal cutting machine 7 composed of a rotary cutter that vertically cuts in the vicinity of the left and right sides of the front and rear surfaces of the carton 1 is provided, and a horizontal slide plate 6 that slides and moves the carton 1 that has been vertically cut horizontally is provided. In the middle of the slide movement path, there is provided a transverse cutting machine 8 composed of a rotary cutter that cuts in the lateral direction in the vicinity of the lower side of the front surface of the carton 1 and the vicinity of the upper and lower sides of the rear surface.
[0013]
A separator 9 for separating the carton 1 and the surrogate freezing block 2 is provided continuously with the transverse cutting machine 8, and the separator 9 is provided with a fixing member 3 for stopping and fixing the lateral sliding movement of the carton 1, An extrusion member 10 is attached to push out the ground freezing block 2 in the carton 1 from the rear surface to the front surface of the carton 1, and an extrusion plate 11 is provided at the tip of the extrusion member 10. The suction cup 12 is attached to the front. In order to remove the waste carton 1 and the empty carton 1 from the separator 9, an adsorber is provided above the separator 9 to carry out the frozen frozen block 2 separated from the separator 9. And a carton remover 14.
[0014]
From the above configuration, the carton 1 packed with the surrogate freezing block 2 moving on the carry-in belt conveyor 3 is moved to the roller conveyor 4 and the cutting process in the longitudinal direction of the previous carton 1 is completed on the roller conveyor 4. Then, the machine is forcibly sent to the longitudinal cutting machine 7. After the position of the carton 1 is adjusted by the positioning member 5 of the longitudinal cutting machine 7, the position of the carton 1 is detected by a limit switch or a sensor, and the position of the cutter and the cutting depth are adjusted.
[0015]
After that, incisions are made in the vicinity of the left and right sides of the front and rear surfaces of the rectangular carton 1 by the rotary cutter of the longitudinal cutting machine 7. The carton 1 incised in the vicinity of the left and right sides of the front and rear surfaces of the carton 1 is pushed by the horizontal slide plate 6 to move in the horizontal direction, and the carton 1 is rotated by the rotary cutter of the horizontal cutting machine 8 installed in the moving path. A cut is made in the lateral direction in the vicinity of the lower side of the front surface and the upper and lower sides of the rear surface of the carton 1 and enters the separator 9. (This incision only cuts the thickness of the carton 1 and is optimally cut to a depth that does not cut the internal slit.)
[0016]
The carton 1 that has entered the separator 9 is temporarily fixed by its position determined by the fixing member 13. When only the surging refrigeration block 2 inside the carton 1 is pushed from the back of the carton 1 by the pushing member 10, the front surface of the carton 1 is opened and the surimi refrigeration block 2 is extruded. At this time, the cut piece of the corrugated cardboard paper separated from the rear surface of the carton 1 is adsorbed by the suction disk 12 attached to the extrusion plate 11 on the front surface of the extrusion member 10, and the suction disk 12 is turned off simultaneously with the return of the extrusion member 10. This leaves the suction disk 12 and remains in the carton 1. The extruded block 2 moves to the carry-out conveyor 15 and is sent out.
[0017]
On the other hand, the carton 1 left in the separator 9 and the cut piece of the corrugated cardboard left in the carton 1 are released from the restraint of the fixing member 13 and are adsorbed by the suction disk of the carton remover 14 descending from above. After being picked up, it moves sideways and is removed from the separator 9. The removed carton 1 cuts three sides on one side and the other side of the opposite two sides, so that the other side can be easily folded at the ridgeline where the carton 1 is folded. it can.
[0018]
As shown in FIG. 3, an extrusion plate 11 for extruding a freezing block 2 in the carton 1 is provided at the tip of an extrusion member 10 that moves forward and backward by a piston and an air cylinder provided in the separator 9. A suction plate 12 is provided on the front surface of 11 to suck and remove the cut pieces of the carton 1. The suction board 12 is connected to a suction machine, and a switching valve for switching between suction and pressurization is attached between the suction board 12 and the suction machine.
[0019]
When the carton 1 with the cuts around the front and rear surfaces comes to the front surface of the separator 9 and is fixed by the fixing member 13, the pushing plate 11 of the separator 9 moves forward and pushes the rear surface of the carton 1 from the rear. At the same time, the cut piece on the rear surface of the carton 1 is sucked by the suction disk 12. Since there are cuts around the front and rear surfaces of the carton 1, when the rear surface of the carton 1 is pushed, the ground freezing block 2 in the carton 1 is pushed and removed from the carton 1.
[0020]
When the extruding plate 11 is retracted, the cut piece is attached to the suction plate 12, but in the carton 1 in the middle of retraction, the switching valve is operated to send pressurized air to the suction plate 12, and the cut piece is detached from the suction plate 12. Then it is left in the empty carton 1. After the surrogate freezing block 2 and the carton 1 are separated in this way, the cut pieces cut out from the carton 1 for separation remain in the emptied carton 1, so that the carton removing machine 14 can remove the empty carton 1 At the same time, since the cut pieces are removed from the separator 9, no cut pieces remain in the separator 9.
[0021]
As shown in FIG. 4, when the carton peeling device for a box-shaped surimi comprising the carry-in conveyors 3, 4, the vertical cutting machine 7, the horizontal cutting machine 8, the separator 9, and the carry-out conveyor 15 is viewed from above, It is arranged in a letter shape. The carton 1 enters the vertical cutting machine 7 provided at right angles from the carry-in conveyors 3, 4, moves laterally from the vertical cutting machine 7, passes through the horizontal cutting machine 8 and enters the separator 9, Separated into a carton 1 and a surrogate freezing block 2, the separated surimi freezing block 2 is carried out by a carry-out conveyor 15 provided at a right angle, and an empty carton 1 is also separated by a carton removing machine 14. Removed from.
When arranged as described above, it is possible to carry in and out the surrogate freezing block 2 at one place. In addition, it can be arranged in an L shape.
[0022]
【The invention's effect】
