Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device used in corrugated board manufacturing to stack a required number of corrugated sheets cut into predetermined dimensions by a rotary cutter and send them out using a transverse feed roll.

In this type of corrugated board manufacturing equipment, the fifth to
As shown in Figure 6, the cardboard sheets sent from the delivery conveyor 13 are transferred to the long wrap conveyor 1.
Shutter gate 12 provided at the tip of the shutter gate 1
The sheets are dropped one by one onto the side feed roll 14 which has a higher head, so if the head is large, the edge of the stacked sheets will be uneven due to wind pressure resistance, and the sheets will be fed sideways with misalignment at the top and bottom. As a result, the separation work is time-consuming and the reversing work is also hindered, which hinders the automation of the next process.

Furthermore, since a long lap conveyor is used, the entire device becomes very large, and in addition, a shutter gate is required to prevent sheets from being fed from the lap conveyor while side unloading is being carried out, making the structure complicated and costly. It was inevitable that this would happen.

The present invention was developed to address these conventional drawbacks, and one of its purposes is to reduce the weight caused by wind pressure resistance caused by the drop of paper by using the elevating paper receiving mechanism used in the bookbinding process. It is an object of the present invention to provide a horizontal unloading device for a corrugated board manufacturing machine that can completely eliminate misalignment of stacked sheets and sideways unload a set number of stacked sheets in an orderly manner. The object of the present invention is to provide a device that can operate continuously without interrupting the supply of corrugated cardboard sheets from a delivery conveyor even during delivery. Another purpose is to provide a device that is simple in structure and inexpensive to implement because it does not require a long lap conveyor, so the overall installation space is small and compact, and there is no need for a shutter gate as in the past. be.

In order to achieve the above object, the present invention includes a rotary cutter 1.1 that cuts a continuous corrugated sheet 2 into a predetermined size, and a rotary cutter 1.1 that separates the sheet cut by the rotary cutter from the following one at the same time as cutting. In a corrugated board manufacturing machine comprising a delivery conveyor 3 that is rapidly fed so as to be sent onto a side delivery roll 5, and a quantity detection counter 9 that detects a set number of sheets sent out from the delivery conveyor 3, the delivery conveyor 3
This delivery conveyor 3 is located in front of the delivery port of
A sheet receiver 6 receives corrugated cardboard sheets sent out from the upper limit position in a superimposed manner and moves up and down between the upper limit position and the lower limit position so that when the set number of sheets is reached, the sheet receptacle 6 moves up and down between the upper limit position and the lower limit position so that the sheets fall into the space between the side feed rolls 5 and 5 located directly below.
When the sheet receiver 6 is lowered and inserted between the side feed rolls 5.5, two end supports project horizontally to the upper limit position of the sheet receiver 6 and receive the supplied sheet so as to separate it from the previous one. A shutter 8 consisting of an elastic belt is located between the delivery conveyor 3 and the sheet receiver 6, and once receives the sheets sent out from the delivery conveyor 3, and supplies the sheets onto the sheet receiver 6 at the upper limit position to supply the set number of sheets. an auxiliary conveyor 4 that is driven to temporarily stop the supply until the shutter 8 protrudes when reaching the
It is made up of the following.

The details will be explained below with reference to the embodiments shown in the drawings.

In FIGS. 1 and 2, reference numeral 1 denotes a pair of upper and lower rotary cutters, which cut a continuous long corrugated cardboard sheet 2 into predetermined dimensions. Reference numeral 3 designates a pair of upper and lower delivery conveyors, in which the corrugated cardboard sheets cut by the rotary cutter 1 are separated from the following ones by rapid feed at the same time as the cutting, and then conveyed to the auxiliary conveyor 4.
It serves to feed the material to the side feed roll 5 through the .
The side feed roll 5 feeds the sheets 2 in a direction perpendicular to the feeding direction of the delivery conveyor 3 and the auxiliary conveyor 4.
They are arranged in multiple rows at predetermined intervals and constantly rotate during operation. This side roll 5
is installed with a predetermined head at the delivery position of the auxiliary conveyor 4. Reference numeral 6 denotes a comb-shaped sheet receiver that is provided to be able to rise and fall vertically between each side delivery roll 5.5, and is connected to the delivery conveyor 3.
The sheets 2 sent out one after another are received at the upper limit position, and when the set number of sheets is reached, the sheets 2 are recessed into the side feed rolls 5.5.... Reference numeral 7 denotes a stopper provided at the front end of the seat receiver 6, against which the front end of the seat 2 is brought into alignment to align the front ends, and its setting position can be freely adjusted. Reference numeral 8 denotes a shutter that protrudes freely from the rear at the upper part of the sheet receiver 6, and when the sheet receiver 6 is retracted between the side rolls 5, 5,... The shutter 8 is to temporarily receive the subsequent supplied sheet 2''.This shutter 8 can be of a panel movable type, a telescopic multi-stage type, or any other appropriate means that can normally be considered. Generally, a belt 8a with both ends fixed is connected by a chain 8b and guided by a guide roller 8c or the like.

In the above configuration, when a corrugated cardboard sheet 2 sent from a slitter or the like is fed between the rotary cutters 1.1, the sheet is cut into a set size and at the same time is rapidly forwarded by the delivery conveyors 3, 3, and is separated from the following one. be separated. A counter 9 for quantity detection is provided on the delivery conveyor 3 and counts the cut sheets passing therethrough. The sheets leaving the conveyor 3 are supplied via an auxiliary conveyor 4 onto an elevating sheet receiver 6 which is placed in advance at an upper limit position, and when a set count is reached, the auxiliary conveyor 4 is temporarily stopped. At the same time, the sheet receiver 6 is lowered and the upper surface of the sheet loaded thereon is exposed to the shutter 8.
When the shutter 8 stops at a position slightly below the lower surface of the shutter 8, the shutter 8 protrudes and stops in front of the stopper 7. The auxiliary conveyor 4 then starts moving again. Next, the sheet receiver 6, which had previously descended to a certain position and stopped, descends from the midway position to the lower limit position and sinks into the side feed rolls 5, 5, . . . . Therefore, the sheets 2' that have been stacked thereon come into contact with the horizontal delivery roll 5, and at that moment the stacked sheets are sent out in the horizontal direction.

On the other hand, above it, the shutter 8 starts receiving the next sheet to be supplied. When the traversal discharge is completed in this way, the sheet receiver 6 rises again to the upper limit position and stops, and at the same time the shutter 8 retracts, and the same operation can be repeated thereafter.

The present invention has the above-mentioned structure, and even when the head difference is large, the sheet receiver is placed on standby at the upper limit position to receive the set number of sheets, thereby completely eliminating the disturbance of sheets that occurs when they fall naturally. A predetermined number of stacked sheets can be taken out horizontally in an orderly manner, and at the same time as the sheet tray is lowered, a shutter consisting of an elastic belt supported at both ends protrudes horizontally to the upper limit position of the sheet tray, and the sheet can be taken out horizontally while blocking the upper part. Since the shutter is completed and the subsequent sheets are received one after another onto the shutter during that time, the shutter operation is quick and the work is carried out smoothly and speedily with high efficiency, and it is possible to sufficiently cope with heavy and large-sized corrugated cardboard sheets. In particular, in this invention, an auxiliary conveyor is provided between the delivery conveyor and the sheet receiver, and this is configured to be stopped when necessary, so that the sheets sent from the delivery conveyor are sent to the sheet receiver at the upper limit position. When a set count is reached during feeding, the feeding of the next sheet is temporarily stopped until the shutter finishes protruding, thereby preventing subsequent sheets from being fed onto the sheet receiver after counting. Therefore, the amount of loaded sheets that are fed out laterally is constant and accurate, and the subsequent ejecting operation of the shutter is performed smoothly without any hindrance, and there is no need to disturb the stacked sheets on the sheet receiver by scattering them with the shutter. This series of operations can be easily performed without using the conventional long lap conveyor or shutter gate, and it has excellent practical effects such as a small installation space and a significant cost reduction. have
