Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves sorting bread containing objects to be sorted such as fruits during the transportation process, and transporting the objects to be sorted on the bread to a boxing location corresponding to the sorting stage. The present invention relates to an aligning device for aligning breads containing sorted items at a boxing location in a sorting device for sorting and packaging.

In conventional sorting devices, whether using the chain packet method or the belt conveyance method, the objects to be sorted after sorting are dropped from packets or belts into sorting trays for each category, so contact between the objects to be sorted occurs. Therefore, the objects to be sorted after sorting inevitably have scratches, which is a factor that reduces the product value.

Therefore, the present invention proposes a sorting device that transports a pan containing items to be sorted and, after sorting, transports the items stored in the pan to a boxing location as an apparatus to solve the above-mentioned problems. The bread that has been transported to the packaging area is lined up, and as a result,
It is an object of the present invention to provide an alignment device that allows the objects to be sorted on the pan to be easily packed into boxes.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, reference numeral 56 denotes a carry-in conveyor for conveying a substantially square bread P containing and supporting the sorted items after sorting, and this carry-in conveyor 56 includes a plurality of rollers as shown in FIG. 57 are arranged at a constant pitch, and a drive pulley 5B is opposed from below to the rollers 57 in the first half of the rollers, and the rollers 57 are rotated with a belt 59 interposed therebetween.

Note that there is no rotational drive mechanism in the latter half of this roller 57, and from there onwards, it is sequentially sent forward by the subsequent feeding of the bread P.

A spring 6 is attached to the tip of this carry-in conveyor 56.
In addition to providing an alignment stopper 61 energized at 0,
An alignment detector 62 such as a microswitch is provided at the operating position of the alignment stopper 61, and the detector 62 detects that a certain amount of running dust has been stored on the carry-in conveyor 56. 63 is activated.

The transfer mechanism 63 transfers a predetermined number of breads P lined up at the tip of the carry-in conveyor 56 in parallel to an accumulation conveyor 81, which will be described later. A scraping plate 65 having both side plates 64 is provided on one side of the rear half of the conveyor 56, a guide frame 66 is extended upward from the scraping plate 65, and guide rollers 67 mounted on both sides of the frame 66 are inserted into the conveyor. conveyor 56
The piston rod 71 of a cylinder 70 fixed to the main body 68 is connected to the center of the guide frame 66.

Reference numeral 81 denotes an accumulation conveyor that conveys a predetermined number of breads P in parallel, and as shown in FIGS. 2 and 3, the conveyor 5
The bread P transferred by the transfer mechanism 63 is rotated by a chain 84 connected to both ends of a roller 82 which is arranged at right angles to the tip of the bread P and is arranged at a constant pitch in the approximately front half of the roller 82. are conveyed forward in parallel and delivered to a roller 85 rotatably mounted forward at a constant pitch.

The roller 82 has a nylon pipe 87 rotatably inserted into a shaft 86 whose both ends are connected to a chain 84. Therefore, when a certain load is applied, the pipe 8
7 rotates relative to the shaft 86.

In addition, an accumulation detector 88 is provided in the middle of the accumulation conveyor 81, which detects when the number of breads P stored on the accumulation conveyor 81 reaches a certain amount and activates an alarm device. .

Further, a discharge conveyor 8 is provided at the front end of this accumulation conveyor 81.
9 will be provided.

A discharge conveyor 89 carries an empty pan P from which the objects to be sorted have been taken out.
As shown in FIGS. 3 and 4, a cylinder 9 is fixed to the main body 68 at the center of an elevator platform 91 with parallel links 90 formed on both sides.
2 piston rods 93 are connected, and a plurality of pulleys 94 are arranged on the upper surface thereof at a constant pitch perpendicular to the accumulation conveyor 81, and the rotation from a motor 95 is applied to each pulley 94 by a tightener 96. It is transmitted by a belt 97.

The cylinder 92 and motor 95 are each controlled by a signal from a boxing detector 98 such as a light emitter/receiver provided on the front end side of the accumulating conveyor 81.

Further, a roller stopper 99 as a separation stopper is provided on the front edge of the lifting table 91, and a stopper plate 100 is provided on the support shaft 90a, which is the rotation axis of the parallel link 90, so as to protrude above the accumulating conveyor 81.

'+0+ is a roller-type discharge conveyor, whose base end is connected to one side of the discharge conveyor 89, and whose tip end is installed in a downwardly inclined manner.
The empty bread P discharged from the pan P is sent out by running under its own weight.

With this configuration, when the pans P storing the sorted objects after sorting are sequentially conveyed by the carry-in conveyor 56,
The first half of the conveyance is sent out by the drive of the belt 59, and then it is gradually pushed out by the sending out of the following bread P, and when the bread P has been sent out a certain amount, its tip pushes back the alignment stopper 61 against the spring 60, and the bread is aligned. The detector 62 detects that a certain amount of bread P has accumulated.

Then, the detection signal is input to the transfer mechanism 63, and the cylinder 70 is actuated to move the scraper plate 65 forward and remove the predetermined number of breads P stored in front of it in a row in a direction perpendicular to the previous conveyance direction. Extrusion accumulating conveyor 81 in parallel with
Transfer to.

At this time, the scraping plate 65 prevents the bread P sent to the carry-in conveyor 56 from moving forward with its side plate 64, and at the same time, the forward stroke of the cylinder 70 is detected and is returned to its original position by reverse operation of the cylinder 70. , the bread P is sent from the carry-in conveyor 56 again.

The bread P transferred to the accumulating conveyor 81 is conveyed in parallel by the drive of the chain 84 to the stopper plate 100 at the tip, where it is stored in running dust.

At this time, the boxing detector 98 detects the entry of the bread P due to the object to be sorted on the bread P in the frontmost row, and operates the cylinder 92 of the discharge conveyor 89 based on the detection signal.

In this case, when the cylinder 92 is activated, the lifting platform 91
are raised in parallel by the parallel link 90, and the pulley 94 comes into contact with the bottom surface of the bread P, and the roller stopper 99 is raised to prevent the following bread P from moving forward, separating it from the bread P in the front row.

At the same time, the stopper plate 100 also rotates in the direction of the arrow in FIG. 3 to release the pressing of the bread P in the front row.

Here, the objects to be sorted placed on the pan P are removed and the objects to be sorted are packed in boxes.

Note that if a certain amount of items to be sorted are left in running stock on the accumulation conveyor 81 without being removed, an alarm device is activated by the accumulation detector 88, so that boxing operations at other locations cannot be carried out until the alarm device is activated. can.

When all the items to be sorted from the bread P in the front row are removed, the cartoning detector 1981 detects the completion of cartoning, and the motor 95 is rotated by the detection signal, and the empty bread P is is discharged to the next discharge conveyor 101.

Then, the time when all the bread P is discharged is detected by a timer or the like, and when the cylinder 92 is operated in reverse according to the signal, the stopper plate 100 is rotated back to its original upright state, and at the same time, the roller stopper 99 is lowered. The next predetermined number of breads P containing the items to be sorted are transported to the front row, and the packing operation is repeated again.

Note that the empty pan P transferred to the discharge conveyor 101 is used again to store and support the objects to be sorted before being sorted, and to be used for sorting and transporting to the boxing place.

According to the present invention, when a predetermined number of pans containing sorted objects are lined up at the tip of the carry-in conveyor.

Since the transfer mechanism transfers the predetermined number of breads to the accumulating conveyor in parallel, it is possible to sequentially arrange a large number of breads in parallel on the accumulating conveyor. It is easy to carry out, and since the breads are lined up in parallel, it is suitable not only for manual boxing work but also for mechanical packaging work, especially since the breads in the front row are separated from the following breads. In addition, when the items to be sorted are removed from the front row of pans lined up on the accumulating conveyor, the empty pans are automatically discharged by the discharge conveyor, making it easy to handle the empty pans by hand. There is no need to remove the bread with a holder, and since the bread is discharged separately from the subsequent bread, only the empty bread can be reliably discharged, and the boxing work can be carried out efficiently.
