あった。[Problems to be Solved by the Prior Art and Invention] As a means for packing fruits or the like in a storage box with less impact, the receiving frame on which the storage box is placed is kept in an inclined posture by using the elastic force of the spring to remove the fruits and the like. Although there is a conventional technique that ends the packing of a predetermined weight while gradually changing to the upright posture while accommodating and accommodating the weight to be accommodated, in this form, the box that maintains the inclined posture by the spring elastic force is unstable. However, if you take out the storage box from the storage box of the box that has stored fruits and returned to the upright position, the storage box of the box will suddenly shift to the tilted position, which is dangerous, and breakdown of the receiving frame etc. is likely to occur. It is desirable to provide a tilt posture maintenance device, an upright posture maintenance device, and a return device that can gradually return from an upright posture to a tilt posture. In the case of an automated device equipped with these devices, the weight stored in the box Gradually by If a spring is used to shift from the tilted posture to the upright posture, the spring has a short life and tension adjustment is complicated, and the automatic operation of the entire weighing and packaging device becomes unstable, causing a failure. It had the drawback of becoming easier.

され略直立の姿勢に復帰する。The fruit supply to the storage box 3 is continued, and when the balance 1 detects the supply of a predetermined weight of fruit, the fruit supply is stopped.
Based on the detection of the predetermined weight, the return solenoid valve 38 is switched to the compression side of the cylinder 5 and the solenoid valve 35 is switched to the open state in which the pipe portion is opened. Therefore, the cylinder 5 is forcibly contracted to be in a substantially upright posture. Return.
従って、直立の姿勢に推移させるためのばねの如き格
別の構成を用いないで足りる。然も、一定重量に達して
以後の収容箱３の直立復帰の動作が迅速化されるため、
排出動作を円滑なものにしうるものである。Therefore, it is not necessary to use a special structure such as a spring for changing the posture to the upright posture. However, since the operation of returning the container box 3 upright after reaching a certain weight is speeded up,
The discharging operation can be made smooth.

12, the solenoid valve 36 is placed in the closed position as shown in the drawing, and the solenoid valve 38 is connected to the silencer 37 as shown in the drawing. When switched to the position, the air pressure of the pressure source 26 is changed from the branch 31 to the solenoid valve.
32, via the speed controller 33, enters the cylinder 5 to extend the telescopic rod 22 of the cylinder 5, and the box receiving frame 4 on which the storage box 3 is placed is pushed up by the telescopic rod 22 and tilts upward.
The speed controller 33 adjusts and changes the ascending tilt speed to a suitable speed. Due to the extension of the cylinder 5, the air on the side opposite to the air pressure receiving side in the cylinder 5 passes through the speed controller 39 and the solenoid valve.
It is emitted from the silencer 37 of 38 to the outside of the circuit 6.

入される。When the box receiving frame 4 reaches the tilt upper limit predetermined position, the solenoid valve 32 is switched to the illustrated relief valve 7a connecting position and the box receiving frame 4 and the housing box 3 are tilted due to the detection of a sensor for detecting this position. The fruit feeding device while maintaining the posture
The motor 50 of 45 is started and rotated to supply the fruit to the storage box 3. The fruit moves into the sloping housing box 3 with less impact due to the drop, and as the transfer amount increases, the air between the cylinder 5 and the speed controller 33 electrode valve 32 and the relief valve 7a acts as an air spring due to the weight of the fruit. The relief pressure of the relief valve 7a, which has been adjusted and changed, is released to the outside of the pressure circuit 6 to the extent that the cylinder 5 contracts, and the housing box 3 descends in the vertical posture direction. At this time, air is sucked from the silencer 37 of the solenoid valve 38 to the telescopic rod 22 side in the cylinder 5.

れを搬送する。On the other hand, the scale 1 continues to measure the weight of the fruit from the beginning of supply, and when it reaches 18 kg, which is 90% of the predetermined weight of 20 kg per box, the endless belt at the fruit supply position 45 is sent by the signal of the sensor of the scale 1.
The conveyor of 48 is stopped, and the conveyor of the brush rolls 47, 47 supplies the fruits arranged one by one. When this one piece supply is continued and the balance 1 detects that the set weight of 20 kg is reached, the sensor emits a signal. Upon receiving this signal,
The rotation of the brush rolls 47, 47 is stopped, and in the pressure circuit 6, the solenoid valve 38 is switched to the side where the cylinder 5 contracts (the side opposite to that shown in the drawing), and
The numeral 35 is for switching to the air discharge position. For this reason, the box receiving frame 4 on which the storage box 3 filled with fruits is placed quickly returns to the upright position and is stably pressed. Subsequently, the supply conveyor 42 sends the empty storage box 3 to the box receiving frame 4, and the storage box 3 filled with the fruit is pushed out to the unloading conveyor 43, and the unloading conveyor 43 conveys it.

で目的の作用をさせることができるものである。The operation different from the case of the large box 3 when packing 10 kg of fruit into the small box 3 is that the solenoid valve 36 is switched to the tilted posture holding position of the box 3 connected to the relief valve 7b for the small box 3 and then the solenoid valve is operated. 32
When the cylinder 5 is switched between the extended position and the maintenance position, the small box 3 is kept in the inclined position and when the fruit is supplied, the weight of the fruit separates it from the branch portion 34 of the circuit 6, and the solenoid valve. 32 side relief valve 7a and solenoid valve 36 side relief valve 7b
The pipe from the cylinder 5 is connected to and, but since the relief pressure of the relief valve 7b for the small box on the solenoid valve 36 side is weaker than that for the large box, the weak side operates and air is discharged to the outside of the circuit 6. It is possible to have a desired effect.

When the switch 40 is switched to the retracted position of the cylinders 16 and 16 opposite to the one shown in the drawing at the same time as the switch of the cylinder 5 to the extended position of the cylinder 5, the small box 3 rises along the vertical member 13 of the box receiving frame 4 while tilting upward. In the upper tilt posture maintaining position, the upper end of the flap 8 of the box 3 is at the same height as the same part of the large box 3, and the fruit can be smoothly supplied. Further, when the small box 3 reaches the upright position with a certain amount of fruits packed, when the switching valve 40 is switched to the cylinder 16, 16 extension position (the position shown in the drawing), the lateral member 12 of the box receiving frame 4 is lowered and lowered. This is the side position b, which is a position where the supply conveyor 42 of the empty box 3 and the carry-out conveyor 43 of the packed box 3 are smoothly communicated with each other, and the storage box 3 can be replaced with the box receiving frame 4.

It is good because it can be used in a wide range.
