Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a feeding device that separates and feeds laminated plate-shaped pulp base paper (hereinafter referred to as paperboard) one by one.

[Conventional technology and issues]

Paperboard stacked in a layered manner adheres to each other during transportation or storage, so in order to mechanically feed one sheet at a time, it is necessary to separate the paperboards before feeding. A device is known in which the paperboard is placed on a paperboard stacking table after being handled by hand, and the paperboard is fed one by one using a suction cup or the like.

However, manual sorting and transshipment work takes a lot of time, and has the disadvantage that a plurality of sheets may be fed at the same time due to poor sorting.

An object of the present invention is to provide a paperboard feeding device that can feed laminated paperboard one sheet at a time without handling the paperboard by hand.

[Means to solve the problem]

In order to achieve the above object, the paperboard feeding device of the present invention includes a paperboard loading table equipped with a moving means for placing a plurality of stacked sheets of paperboard leaning against each other and moving within the machine frame; a paperboard front detector that is attached and detects the paperboard located at the forefront in the moving direction and sends a stop signal to the moving means; a paperboard feeding member that moves the stopped paperboard at the forefront upward; and a paperboard feeding member provided on the machine frame. In the paperboard feeding device, the feeding member is rotatably provided on the machine frame and is perpendicular to the direction of movement of the paperboard stacking table. a drive shaft having an axial center; an arm-like member having one end pivotally connected to the drive shaft and hanging down; a sprocket fixed to the drive shaft; and a sprocket rotatably pivotally connected to the arm-like member. The present invention has a structure including an endless chain wound around the endless chain, and a needle hook provided on a pedestal metal fitting fixed to the endless chain and having a tip hooked to the frontmost paperboard.

[Effect]

The operation of the paperboard feeding device configured as described above is as follows.

When a paperboard loading table on which multiple sheets of paperboard are stacked against each other is moved by a moving means, and the paperboard at the forefront is detected by the paperboard front detector,
A stop signal issued from the paperboard front detector causes the moving means to stop, and the frontmost paperboard is positioned at a predetermined position.

At this time, the endless chain provided on the arm-shaped member hanging down from the drive shaft comes into contact with the front surface of the paperboard located at the forefront, and the tip of the needle hook comes into contact with this paperboard.

Next, when the endless chain rotates, the needle hook rises, and only the frontmost paperboard that is locked to the needle hook moves upward together with the needle hook, and is further fed upward by a pair of delivery rollers.

The remaining paperboard remains on the paperboard stacking table due to its own weight.

Next, when the paperboard loading table is moved again, when it has moved by the thickness of the paperboard, it is detected by the paperboard front detector and stops, and the new paperboard that is now at the front is moved upward in the same way. They move and are supplied one after another.

This compressed air blowing means C is for flowing air into the laminated surface of the paperboards 4 to smoothly separate the paperboards 4 from each other, and blows out compressed air in synchronization with the rotation of the paperboard feeding member B. is configured to do so.

The operation of this device will be explained below.

The paperboard loading table 2 is equipped with operation switches, etc. (not shown)
It moves to the left in FIG. 1 and then stops.

Next, a plurality of paperboards 4 are placed on the paperboard stacking table 2 in an upright state, and are leaned against the back plate 2-2.

Therefore, each surface of each paperboard 4 is approximately parallel to the back plate 2-2.

After loading, the paperboard loading platform 2 is moved again in the direction of the paperboard feeding member B by an operation switch or the like, and the paperboard 4 at the forefront in the traveling direction presses the paperboard cargo tracking rod 32, causing the upper header 23 and the lower header 27 to move. After the front side of the paperboard 4 is bent to match the packaging, the front side of the paperboard 4 is detected by the paperboard front detector 3, and a detection signal causes the electric motor 35 with a transmission to stop, and the frontmost paperboard 4 returns to the reference position. Stop.

In this state, the arm-shaped member 8 of the paperboard feeding member B is pushed by the front surface of the paperboard 4 and is pushed up about the drive shaft 7, and the endless chain 12 matches the front inclination angle of the paperboard 4.

An electric motor (not shown) rotates and the endless chain 7
-2, the drive shaft 7 rotates, and the endless chain 12
travels in the direction of arrow 34, the needle hook 13 moves upward while hooking on the paperboard 4 at the frontmost position, and the paperboard 4 at the frontmost position is transferred to the delivery roller 38.

Since the circumferential speed of the feed roller 38 is faster than the circumferential speed of the endless chain 12, the paperboard 4 fed upward by the feed roller 38 naturally comes off the needle hook 13.

On the other hand, when the frontmost paperboard 4 is sent up by the paperboard feeding upper member B, the compressed air jet nozzle 3 is activated by a solenoid valve (not shown) that is open during the operation period.
Compressed air is blown from 1 to the laminated surface of the paperboards 4, and the air is sent between each paperboard 4 to separate the paperboards 4.

At the same time, the eccentric roller 33 in contact with the paperboard 4 is rotated as the paperboard 4 rises, shaking the paperboard packaging tracking rod 32, the upper air header 23, the lower air header 27, and the compressed air jet nozzle 31. To ensure more reliable handling of paperboard 4.

When the frontmost paperboard 4 is fed into the feed roller 38, the paperboard 4 that is newly the frontmost paperboard 4 among the remaining paperboards 4 is in a position where it is not detected by the paperboard front detector 3, so the paperboard stacking is started again. When the table 2 moves forward and is detected by the paperboard front detector 3, the paperboard stacking table 2 stops, and the new frontmost paperboard 4 is transferred upward by the same operation as described above.

[Effect of idea]

Since the present invention is configured as described above, it produces the following effects.

The position of the endless chain of the paperboard feeding member follows the frontmost paperboard load, and the needle hook hooks only the frontmost paperboard and lifts it upward, so the remaining paperboard is placed on the paperboard stacking table. This ensures that the paperboard is fed upwards one by one.

Furthermore, when compressed air blowing means is used as an auxiliary aid, the separation and feeding of paperboard sheets one by one becomes more reliable and more stable feeding can be achieved.
