Thereafter, with operation of the distribution plate 3, the packaging case 1 is thrown into the loading bench 4. The loading bench 4 is intermittently lowered step by step each time the packaging case 1 is thrown in, and lowering of the bench at each step is controlled by sensing of an optical sensor 29. Thereafter, the pckaging case 1 on the loading bench 4 is pushed back onto the transfer conveyor 2 by a return plate 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sorting and loading device for packaging cases such as dried noodles (for example, cardboard cases).
For example, it is an object of the present invention to provide a sorting and loading device for packaging cases that can be transported during a bundling process.

Conventionally, packaging cases for dried noodles and the like have been transported one by one on a transfer conveyor and then wrapped one by one in a binding device with tape. In addition, when stacking multiple tiers and attaching tape, the stacked packaging cases are manually loaded into a binding device.

Therefore, this imposes a large labor burden on the operator, and when multiple packaging cases are transported on the conveyor,
There was a drawback that different types of items could be mistakenly stacked on top of each other.

The packaging case sorting and loading device of the present invention solves the above-mentioned drawbacks of the conventional example, and includes a packaging case transfer conveyor,
It is installed vertically above the transfer conveyor, and the distribution part that advances and retreats at right angles to the transfer direction of the packaging case is a plate, and the distribution part is arranged on both sides of the transfer conveyor at the position of the plate, and the upper end is connected to the transfer surface of the transfer conveyor. The present invention is characterized by having a loading platform that is movable up and down so as to be equal to the height of the loading platform, and a return plate that pushes back the packaging cases stacked in multiple stages from the outside of the loading platform toward the transfer conveyor.

The present invention will be described below with reference to an embodiment based on the drawings.

In the figure, / is a packaging case with a barcode B indicating the type of product attached to the side, and the packaged state is transported by a transfer conveyor d consisting of a bar conveyor or the like to a position where it can be loaded into a bundling device. A board 3 is vertically disposed on the transfer conveyor 4 at this position in parallel with the direction of movement thereof, and moves back and forth across the direction of transfer of the packaging case at a right angle. A reader 7 is attached to the front stage of the transfer conveyor d, and reads the signal of the bar code B given to the packaging case/, and automatically stops the transfer conveyor d. This transfer conveyor uses a stepped pulley to drive the motor.
2, is transmitted to the belt /j via the tension pulley /3 and slave pulley /da, and to the belt /j, respectively,
The transfer conveyor is driven at a low speed before reader 7,
It is driven past the reader 7 at high speed.

A reader 7 installed along one side of the transfer conveyor ρ reads the light projected from the light source 8 on the opposite side and the light projected from the light source 2 in the same direction and reflected by the packaging case. That is, a stopper and a stopper 2, which will be described later, are activated using the fact that the light from the light source 8 is blocked as a signal. On the other hand, using the light projected from the light source and reflected by the barcode part of the packaging case as a signal, the board 3 sorts the packaging cases according to a command read from the microprocessor. ,,2/and,,2. ．． 2 is a guide installed on both sides of the transfer conveyor just before the reader 7;
The rear end is slightly longer. The cylinder , 23 installed on the opposing part of the guide 2/ causes the stopper 2 to protrude in response to a signal that the light from the light source 8 entering the reader 7 is blocked by the packaging case/. The packaging case / that has been transported is clamped between the rear end of / and the packaging case l is stopped so that the barcode B can be easily read by the reader 7.

As for the distribution, board 3 is a slide bearing,,! Limino 1, which is supported on the transfer conveyor d by 6 and detects the arrival of the packaging case/, is linked with a switch ρ2, and a cylinder fixed to the side of the transfer conveyor ρ, and 2 which detects the transfer conveyor by 2. Move back and forth across the street and sort the packaging cases. .

On both sides of the transfer conveyor 1.2 on which the plate 3 is located, loading tables are provided which are held on the same plane. This loading platform has a linear reciprocating function and has two motors.
8, it is configured such that it can be freely lowered, and the distribution is divided from the transfer container/a by the plate 3.
It descends every time it is loaded with A. When the packaging case has been lowered to a predetermined height, it is placed across the loading platform.
The optical sensor 29 senses this and stops the lowering of the loading platform. At the end of loading, the number of passing packaging cases is read, and the fIt platform is automatically raised to its original position in accordance with the read signal (number of packaging cases of the same type). That is, the loading platform is controlled so that its upper end is always equal to the transfer surface of the transfer conveyor, both when it is empty and when it is loaded.

j is a return plate, which is used to hold cylinders 3/3 installed on the outside of the loading platform.
is attached to. The return plate 6 moves forward when the loading platform rises to its original position, and pushes back the packaging cases stacked in multiple stages onto the transfer conveyor. At this time, the plate 3 pinches between the return plate 6 the multi-tiered packaging cases that have been pushed back towards the transfer conveyor, 21\, by the return plate 6, and corrects the stacking deviation. The vehicle moves backward according to a predetermined 1-lux.

Next, to explain the function of the packaging case sorting and loading device of the present invention, first, the packaging cases / that are conveyed on the transfer conveyor d and passed between the guides +:, x/1, 2.2 at low speed are: The stopper 29 is operated by blocking the light from the light source 8,
The reader 7 reads the signal related to the product type written on the barcode 2 by the light source while the barcode 2 is connected to the rear end of the guide 2. At this time, the distribution is board 3,
In accordance with the command from the reader 7, it moves to a designated position on the left and right ends of the transfer conveyor and waits for the packaging case l. Next, the packaging case/ is conveyed at high speed to the position of the distribution board 3, the arrival of the packaging case/ is detected by the limit switch 27, the transfer conveyor p is stopped at a predetermined position, and the distribution is in the preparation position. actuates the plate 3 and throws the packaging case onto the stacker/plater.

Furthermore, due to the speed difference of the transfer conveyor d, there is a gap between the reader 7 and the distribution plate 3 than before the reader 2. / blocks the light from the light source 8 again, and the stopper
, you will be put on standby for 2 das.

After the packaging case/ is placed on the loading platform, the transfer conveyor equipment is re-driven, and then the waiting packaging case/ is opened by the stopper 2 and moved to the position of the above-mentioned lock 4>bracket 3. The barcode 4 of the transported packaging case 1 is read by the reader 7 while it is on standby, and the packaging cases are sorted onto the same loading table for the same type of packaging case.

The loading platform descends intermittently one step each time a packaging case is loaded, and the lowering of each step is determined by an optical sensor, 27, which indicates that the top surface of the packaging case has descended to approximately the same height as the top surface of the transfer conveyor λ. It will stop when it senses. At the end of loading, the number of passing packaging cases is read, and the loading platform is automatically raised to its original position in accordance with the read signal (number of packaging cases of the same type).

Thereafter, the return plate 6 pushes back the packaging cases stacked in multiple stages on the loading table toward the stopped transfer conveyor d. At that time, the return plate 6 and the switch plate 3 should be placed between the packaging case and the plate 3 to correct the misalignment of stacking.
．． After 2] Make sure there are no obstacles in the 2nd direction. Then, the transfer conveyor ρ is driven again and carries out the packaging cases loaded in multiple stages to a binding device or the like in a subsequent process. The packaging case sorting and loading apparatus of the present invention repeats each of the above operations.

Note that the above limit switch 3. ．． 2, the distributed portion is linked with a shutter 33 that can freely appear and retract from the discharge part of the plate 3 portion, and when the flow of the post-process is stopped, the sheet A/vine 33 is transferred to the transfer conveyor recognition, and is multi-staged. Stacked packaging cases/
Plowing is put on standby.

At this time, the above stopper...! When the door is closed, the packaging is closed/
prevent the influx of At this time, since the transfer conveyor 2 is in motion, the subsequent process begins to flow, and the packaging case/on the switch 3.2 starts the feeding operation.

Since the packaging case sorting and loading device of the present invention is configured as described above, a plurality of packaging cases can be sorted, loaded, and transported to subsequent processes (for example, bundling process, etc.) using a single container/align. can do. Therefore, in addition to taking up less space, the operator's labor burden is significantly reduced by Φ7, and when multiple packaging cases are transported on the transfer conveyor, it is possible to avoid accidentally handling different types of packaging cases. I was able to eliminate the disadvantage of stacking M.

In addition, by sequentially arranging the sorting and loading devices of the present invention along the transfer conveyor, it is possible to easily increase the types of packaging cases that can be sorted and loaded, making it possible to easily respond to changes in the specifications of the conveyor line. Became.
