Description

[Detailed Description of the Invention] The present invention relates to an intermittent feeding device for corrugated cardboard and other plate-like objects.

Conventionally, processing processes for plate-shaped objects such as printing, die-cutting, gluing, etc.
When supplying to the box manufacturing process for assembly, it is common to provide a supply device capable of storing a large number of plate-like bodies, and use this to feed the plate-like bodies in small quantities to a hopper of a printing device or the like.

In this case, it is better to send out several to tens of plates at once than to send out the plates one by one without damaging the plates. It is not possible to send out sheets in units of 10 sheets, and conventionally, a group of plate-like objects had to be stacked vertically on a feeding device, and the sheets had to be manually delivered from one end of the sheet by several to several tens of sheets, one after the other, onto the transfer path. Ta.

For this reason, as shown in Japanese Utility Model Publication No. 47-21818, there is a means for grasping a predetermined number of plate-like bodies as one block at the very end of a moving device that moves a large number of plate-like bodies in a vertically stacked state. There is a known device in which the group of block-shaped plates is separated from the whole group of plate-shaped bodies by the gripping means, and the group of block-shaped plates is taken out. This method is unsuitable for a group of heavy plate-like objects such as corrugated paper, and requires a plurality of apparatus configurations.

On the other hand, as seen in Japanese Patent Publication No. 52-23456, a device is provided rotatably in the direction of movement of the group of plate-like bodies at the very end of a moving device for moving a large group of plate-like bodies in a vertically stacked manner. A sorter equipped with a claw having an upper surface that coincides with the moving surface of the device is provided with a claw member, and when a predetermined number of plate-shaped bodies are placed on the upper surface, the sorter rotates the claw member. An apparatus is known in which the group of plate-like bodies is sorted into one block, and then the receiver is dropped onto the members to separate them.

However, when this type of device is used, the group of plate-like objects is sorted by rotating the claw member, and the receiver is dropped onto the member to separate them, so there is a risk that the group of plate-like objects will fall over at that time. For this reason, a fall prevention means is required, but this has the disadvantage that it cannot sufficiently prevent the fall.

The present invention eliminates these inconveniences and provides an intermittent supply device for plate-like bodies that has a simple structure, can reliably separate a group of block-shaped plate-like bodies, and can feed out the group of plate-like bodies without accidentally overturning the group. It is intended to provide a first moving device 3 for moving a large number of vertically stacked plate-shaped bodies 2 and the whole, and a transfer path disposed downstream of the first moving device 3. 4 and the first moving device 3, and is provided with a feeding device 5 that blocks a part of the plate-shaped body group 2 and feeds it out intermittently to the transfer path 4. a second moving device 6 that moves toward the transfer path 4 from the first moving device 3, which is interposed between the discharge port of the plate group 2 of the first moving device 3 and the inlet of the transfer path 4; 2nd along both sides of 6
The second moving device 6 is provided so as to be movable up and down between the upper and lower positions of the moving surface of the moving device 6, and the first moving device 3 is connected to the second moving device 6.
a support arm 8.8 having an inclined portion 7 for guiding the group of plate-like bodies 2, which is moved towards the upper position, to support it in the upper position; A lifting device 9 that lowers to the position, and a detector 19 provided above the supporting arms 8 and 8 that detects when a part of the plate group 2 is moved onto the supporting arms 8 and 8 by the first moving device 3. 20, and a control device 21 which stops the operation of the first moving device 3 and causes the elevating device 9 to descend for a predetermined period of time in response to a detection signal from the detector 19 or 20.

In the illustrated embodiment of the invention, the machine base 10 of the feeding device 1
, a plurality of parallel checks 711 are used as the first moving device 3.
and an extrusion plate 12 protruding from the surface of the machine base 10 that moves together with the machine base 10, and the machine base 10 is swingably attached to the base frame 13 by means of a support shaft 14.

Then, the machine stand 10 of the first moving device 3 is stood vertically as shown by the chain line in FIG. When the machine is tilted to a substantially horizontal position, the plate group 2 is vertically stacked on the machine base 10, and then the check 711 and the push-out plate 12 are moved in the direction of the arrow by a hydraulic cylinder or other means. The vertically stacked plate-like bodies 2 are sequentially sent out toward a horizontal transfer path 4 provided on the downstream side of the machine stand 10.
