A worker standing by at the discharge port of the belt conveyor unit counts the number of sheets and arranges them in a storage container.

However, since the normal folder / gluer operation is performed at a high speed, for example, 300 m / min, it is impossible for one worker to perform the box packing work. For this reason, a plurality of workers perform the box packing work.

[0004]

In the conventional example, a plurality of workers carry out box packing work, but since the vicinity of the discharge port of the belt conveyor is narrow, a space with good workability is secured for them. It was difficult to do. Therefore, workability was poor and it was not possible to work smoothly.

Further, since the counting of the number of sheets is also performed visually by the worker, it is not always accurate. Therefore, there are cases where a predetermined number of folding boxes cannot be reliably stored in the storage container.

In view of the above circumstances, an object of the present invention is to automatically pack a set number of folding boxes.

A plurality of suction holes 24 are formed in the receiving belt 20 at intervals along the longitudinal direction. The sandwiching portion 25 of the sandwiching belt includes an inclined portion 25a, an arcuate portion 25b, and a vertical portion 25c that are sequentially continuous. The vertical portion 25c can move up and down as shown by an arrow A25,
An outlet 9 and a pressure sensor 26 are provided at the lower end thereof.

A carry-in port 8 is provided below the inclined part 25a. The carry-in port 8 has an exposed part of the receiving belt 20 facing the outlet A ₁ of the transfer path 10 and the receiving belt 8. Two

The counting sensor 27 is a distance sensor,
The receiving belt 20 is provided to face the outside of the movement path of the receiving belt 20.

The stoppers 28 are arranged on both sides of the receiving belt 20 while sandwiching the receiving belt 20 therebetween. The stopper 28
Is rotated by the drive of the drive unit 30 and protrudes to the surface side of the receiving belt 20. The suction port 29 is the suction hole 2 of the receiving belt 20.
It is provided so as to face the movement locus of No. 4.

A storage container 31 placed on a slider 33 is provided below the vertical portion 25C. The slider 33 is provided with a locking portion 35 for restricting the sliding of the container 31.

Next, the operation of this embodiment will be described.
Folding box G folded and glued with folder gluer 2
Is transferred from the belt conveyer unit onto the lower belt 12 of the counting and straightening and feeding device 3, is moved in the direction of the arrow A10 while rising in the transfer path 10 and is conveyed to the outlet unit A _1, and the folding box G is moved to the carry-in unit 8 Abut the receiving belt 20.

At this time, the suction device is operated by the detection of the stay sensor S ₁ and is sucking from the suction port 29 through the suction hole 24, so that the folding boxes G are sucked onto the receiving belt 20 one by one. Meanwhile, it is transferred to the inclined portion 25a of the holding portion 25.

The counting sensor 27 measures the distance to the folding box G on the receiving belt 20, and the folding box G is being transferred.
However, when a step is generated between the folding box G to be transferred next after passing the measurement point of the sensor 27 and the distance is different, a detection signal is output and one sheet is counted.

The count data of the sensor 27 is input to the control device 100. The folding box G is the receiving belt 2
Since it is adsorbed on 0, there will be no displacement etc.
Accurate counting can be done.

The control device 100 includes an input device 101.
In advance, the total number of folding boxes G in one lot (one stroke), the normal operation number of the counting and aligning and supplying device 3 and the aligning and accommodating device 4 are operated at a normal speed, and the speed is made lower than the normal speed. The number of regulated operations to be performed is entered. For example, the total number of folding boxes G is set to 100, the normal operation number is 95, and the regulated operation number is the remaining 5 sheets.
When the counting sensor 27 counts 95 sheets for normal operation, the control device 100 sends a control signal to the drive unit 18 of the counting and aligning and feeding device 3 and the drive unit of the alignment and storage device 4 to slow down the rotation speed. . Then, the upper and lower belts 11, 1
2 and the speed of the belts 20 and 21 becomes slow, for example, from 100 m / min to 20 m / min.

When the speed is controlled in two stages in this way, a large inertial force does not act on the folding box G on the belts 11, 12, 20, 21 and therefore the belts 11, 12, 2,
Even if 0 and 21 are suddenly stopped, the movement of the folding box G is suddenly stopped.

The total number of control devices 100 is 100.
At the same time as counting the number of sheets, the driving unit 30 is driven to stop the stopper 2
Since the pressing portion 28a of the stopper 28 is projected to the front surface side of the receiving belt 20 by rotating 8 in the direction of the arrow A28,
The stopper 28 is in the state shown by the chain line in FIG. 1 and the state shown in FIG. 7. For this reason, the folding box G of the carry-in port 8 that is in contact with the surface of the receiving belt 20 is forcibly separated from the belt 20, so that the supply of the folding box G to the inclined portion 25a is stopped.

A folding box G is provided at the intermediate portion A ₂ of the transfer path 10.
When is excessively retained, the retention intermediate sensor S ₂ is activated to output a detection signal to the control device 100. Since the control device 100 gives an instruction to drive the drive unit 16, the push-up bar 17 is raised to be in the state of alternate long and short dash line as shown in FIG.

Then, since the folding box G on the lower belt 12 is lifted by the push-up bar 17, the lower belt 1
Move away from 2. Therefore, since the progress of the outlet portion A ₁ side of Oribako G is prevented, not an abnormal pressing force is applied to Oribako G in the outlet portion A ₁ side, also the surface of Oribako G from being damaged by the press Absent.

Further, when the folding box G is retained up to the entrance A ₃ of the transfer path 10, the retention increase / decrease sensor S ₃ is activated to output a detection signal to the control device 100. Then, the control device 100 stops the drive unit 6 of the belt conveyor of the gluer 2 and stops the supply of the folding box G to the counting justification supply device 3.

The folding box G supplied to the aligning and storing device 4 is
It passes through the holding part 25 and falls from the carry-out port part 9 of the vertical part 25C into the storage container 31 while being in a vertical state and aligned. When a large number of folding boxes G are aligned between the front wall 31a of the container 31 and the pressure sensor 26 and the pressure sensor 26 is pressed,
The pressure sensor 26 outputs a detection signal to the control device 100.

Then, the control device 100 causes the slider 3
Since the driving unit 36 of No. 3 is driven, the slider 33 moves in the direction of the arrow A33 and reaches the position shown by the alternate long and short dash line. In this way, the slider 33 is slid, and the folding boxes G are automatically packed while ensuring a storage space for the folding boxes G carried into the storage container 31.

The embodiment of the present invention is not limited to the above, and it goes without saying that, for example, only a blank sheet can be used for automatic packaging of a folding box formed of cardboard. Further, it can be used not only for automatic packaging of folding boxes but also for automatic packaging of other products.

[0037]

Since the present invention is configured as described above, the folding boxes can be automatically packed. Also before
The control unit includes the total number of folding boxes in one lot,
The normal operation number and the regulated operation number are input, and the control device
When the counting sensor detects the number of sheets in normal operation,
For normal operation, the counting and assembling feeder is operated at normal speed.
When the number of sheets is detected, the speed is slower than the normal speed.
When operating at high speed and detecting the total number of folding boxes
Stops the supply of folding boxes by driving the stopper.
However, the control device is pre-installed in one lot (one stroke).
Run the total number of folding boxes and the counting and assembling feeder at normal speed
Set the normal operation number and the speed to slower than the normal speed.
Since the number of regulated driving to drive and is entered, counting
The operation speed changes depending on the number of sensors detected. That
Therefore, a large inertial force is applied to the folding boxes on the upper and lower conveyors.
Since there is no such, the folding box moves even if the conveyor is suddenly stopped.
Can be stopped abruptly.

Since a push-up bar which can be moved up and down is provided on the side of the lower conveyor, the push-up lever can be moved upward to separate the folding box from the lower belt when the folding box stays too much in the transfer path. Therefore, it is possible to prevent a large pressing force from being applied to the folding box at the carry-in port, so that it is possible to prevent two sheets from being simultaneously supplied to the aligning and storing device and the surface of the box is not damaged.

Since the retention sensor is provided, the retention state of the folding box in the transfer path can be grasped. Therefore, control for maintaining the folding box in the transfer path in an optimum state becomes easy.

Since the counting means and the supply stopping means are provided at the carry-in port, the folding boxes are conveyed to the aligning and storing device while being counted, and when the set number is reached, the supply is surely stopped by the supply stopping means.

Since the carry-in port is provided with the suction means, the folding box is surely sucked to the receiving belt and is surely conveyed to the aligned storage device. Therefore, since the positional deviation does not occur during the transportation, the counting count can be made accurate.

Since the pressure sensor is provided at the lower end of the sandwiching and transferring means, and the pressure sensor and the slider are connected to each other, the folding box is supplied into the container on the slider, and when the predetermined amount is reached, the pressure sensor operates and the slider moves. Slide. Therefore, the accommodation space of the folding box can be sequentially secured, so that the folding box can be smoothly accommodated.
