Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is an automatic supply device for a packaged product such as a newspaper or a magazine, which is used to separately supply packaged products having different thicknesses to the left and right, one by one. Regarding

[0002]

[Prior Art]

 Conventionally, for example, in the case of tightly packing a newspaper with a large number of folded advertisements, one by one, hold each newspaper and supply it to the packaging machine. The newspaper was hermetically sealed by inserting it into the plastic packaging material and heat-sealing the openings at both ends.

[0003]

[Problems to be solved by the device]

 By the way, in articles to be wrapped such as newspapers and magazines, the thickness on the bent side is thicker than other parts. Therefore, if a large number of layers are stacked without changing the stacking direction, the folded side becomes higher than the unfolded side. The top newspaper cannot be placed in a horizontal position suitable for automatic feeding. As a result, if you try to separate the topmost skewed newspaper by the feeding roller or the needle claws and then feed it, the newspaper will jam or the needle claws will only be on one side of the newspaper. Satisfied feeding cannot be expected due to lockout or slipping out of inserted advertisements.

Therefore, in the conventional packaging machines for newspapers and the like, the present situation is that the articles to be packaged are manually separated and supplied to the packaging machine one by one. In particular, if the newspaper is hermetically wrapped with a synthetic resin sheet, it is easy to handle newspapers with many folded advertisements folded in, and it is possible to prevent the newspapers from getting wet with rain during home delivery in the rain. Can be expected.

[0005]

[Problems to be Solved by the Invention] However, since all of the conventional methods for supplying objects to be packaged are performed manually, a lot of labor is required, and the packaging work becomes complicated and the packaging cost rises. There was a problem that it took a long time. The present invention has been made in view of such a point, and it is possible to stack a large number of articles to be packaged such as newspapers having different left and right thicknesses, and the stacked articles to be packaged are automatically separated one by one from the top. It is an object of the present invention to provide an automatic feeder for the objects to be packaged so that they can be automatically fed to the packaging machine.

[0006]

[Means for Solving the Problems]

 The automatic supply device of the packaged object of the present invention is such that the left and right positions of the mounting table on which the packaged object is placed are connected to different drive sources, and the mounting table is moved up and down, and the mounting table described above. Placement table tilting mechanism that controls the horizontal direction of the packaged items stacked on top of each other, and the horizontal placement state is detected according to the upper limit position of the packaged item and the thickness of the packaged item on the placing table. Then, a detection mechanism for individually stopping the drive source, and a first delivery mechanism for intermittently delivering the packaged articles to the delivery guide port one by one on the basis of the signal from the detection mechanism, and the first delivery mechanism. The second delivery mechanism is configured to deliver the encapsulated article that is intermittently delivered by the mechanism to the packaging machine.

[0007]

[Action]

 The automatic feeding device of the package according to the present invention drives the ascending and descending movements of the mounting table by different driving sources connected to the left and right positions of the mounting table, respectively, and the mounting table tilting mechanism enables the mounting state of the packaged object. Since it is fed to the delivery mechanism intermittently after the horizontal control of the package, even if multiple folded advertisements are sandwiched and the items to be packaged with different left and right thicknesses are stacked on the placing table, The package can be held in a horizontal state suitable for automatic supply, and the stacked products can be separated from the top one by one and automatically supplied to the packaging machine, reducing the packaging work time and handling extremely. It becomes easy. Moreover, since the first delivery mechanism intermittently delivers the articles to be packaged, it can be used for sealing work such as heat welding of the packaging machine.

Next, the operation of the apparatus for automatically supplying the objects to be packaged according to the embodiment of the present invention will be described. First, the connector of the packaging machine B is connected to the outlet of the automatic feeder A (not shown), and the power switch of the packaging machine B is turned on. Next, after turning on the breaker switch 63 of the automatic feeder A, the power switch 64 is turned on. The heater temperature rise time of the packaging machine B is waited (for about 12 minutes), and the buzzer sounds with the elapse of the wait time. Therefore, the buzzer release button 69 is pressed to release the buzzer. Next, the opening / closing door 5 is opened, and the thickness direction generated by the folding of the article 4 to be packaged is unified in one direction and the layers are sequentially stacked on the mounting table 18. In this embodiment, they are integrally laminated on the left side. When the stacking is completed, the opening / closing door 5 is closed, the counter 61 is set to the desired quantity, the operation knob 70 of the level switch is adjusted according to the thickness of the article to be packed, and the start button 68 is pressed. The left and right motors 7 and 8 start driving simultaneously, and the mounting table 18 starts to rise through the slide members 23a to 23d connected to the left and right endless chains 16 and 17, respectively.

As the loading table 18 rises, the left thick surface of the uppermost package 4 on the loading table 18 contacts the upper limit detection roller 36a and pushes up the detection roller 36a, The arms 40a-40b are rotated clockwise about the rotary shaft 40 as a fulcrum to press any one of the corresponding sensing arms 48a-48c of the level switch 48 set by the shaft 50 of the roller arms 40a-40b. , Stop the driving of the motor 7 on the left side of the previous term.

In this state, the upper surface of the right side of the article to be packaged 4 is not yet in contact with the upper limit detection roller 36b on the right side, so that the motor 8 on the right side continues to be driven upward. Therefore, as shown in FIG. 7, the mounting table 18 has its right end raised to a dashed-dotted line state and tilted to the right, causing the upper right side of the package 4 to contact the upper limit detection roller 36b and detect the upper limit of the left side. By the same operation as the roller 36a, the motor 8 on the right side is stopped by pressing any one of the corresponding sensing arms 49a to 49c. The tilting of the mounting table 18 is performed by rocking the rocking members 33, 33 of the hinges 34, 35 attached to the left and right of the mounting table 21.

As described above, the upper surface of the article to be packaged 4 is brought into a horizontal state and both the left and right level switches 48 and 49 are operated, whereby the first feed motor 42 is driven, and Is transmitted to the upper limit detection rollers 36a, 36b and the feed roller 36c via the rotation shaft 40, the package 4 is sandwiched between the guide rollers 51, and is constantly rotated by the second feed motor 52. The second feeding mechanism 54 is sequentially fed to the first feeding rollers 55a and 55b and the second feeding rollers 57a and 57b and stopped. The object to be packaged that has passed through the second feeding roller 57a and is fed to the packaging machine B is counted by the counter detector 60, and the count signal is displayed on the counter 61 of the operation panel 3.

When a part of the article 4 to be packaged is completed, the left and right upper limit detection rollers 36a and 36b form a gap between them and the next article 4 to be packaged. After returning to the state, the left and right motors 7 and 8 are driven again to raise the mounting table 18 until the upper limit detection rollers 36a and 36b come into contact with the uppermost surface of the object to be packaged 4, and the same operation as described above is performed. Is repeated. The first feed motor 42 has a timer for setting the time for feeding the article 4 to the first feeding roller 55a of the second feeding mechanism 54, and takes the time required for the hermetic packaging of the packaging machine B into consideration. Then it is started intermittently.

When all the articles 4 to be packaged are sequentially sent out from the mounting table 18, the limit switch 18a of the mounting table 18 is actuated, the left and right motors 7 and 8 are driven to rotate in reverse, and the mounting table 18 is lowered. Then, the descending end of the mounting table 18 descends until the left and right descending end position detection limit switches 74, 75 are respectively detected, and when the mounting table 18 becomes horizontal, the buzzer sounds and the left and right motors are moved. 7, 8 stop. Therefore, the buzzer release button 69 is pressed to wait for the next automatic supply work.

In the above embodiment, the motors 7 and 8 are used as the drive sources of the drive mechanism 19 of the mounting table 18, and the endless chains 16 and 17 are used to move up and down, but the present invention is not limited to this. Of course, the hoisting machine using an air cylinder or a pulley may be used to raise and lower the mounting table 18. Further, it goes without saying that the pair of left and right hinges 34, 35 mounted on the lower surface of the mounting table 18 may be mounted on the left and right sides in reverse.
