JPH08258985A - Packaging tray takeout device - Google Patents

Abstract

PURPOSE: To improve working efficiency by setting packed packaging trays to a main body in a narrow place and taking out the trays one by one by means of a single hand when food and the like is packaged. CONSTITUTION: In a packaging tray takeout device, a transmitting device, via which a wheel brush 4 and a conveying belt 2 are interlocked with each other, is installed in a driving motor 5. In one side of the transmitting device, a base shaft pulley 8 is installed in the driving motor 5, and connection to the conveying belt 2 is carried out by installing a conveying pulley 10 and a conveying belt lower shaft 3 via a driving belt 11. In the other side, a gear 6 for the wheel brush is geared with a base shaft gear 9 installed in the driving motor 5, and connection to the wheel brush 4 is carried out by installing a pulley 13 for the wheel brush via a coaxial pulley 7 and a belt 12 for the brush. In a tray takeout port, a sensor 15 for detecting a tray is installed, and transmission to the driving motor 5 is carried out.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for taking out a packaging tray.

[Prior Art] Conventionally, the packaging trays packed in dozens of cases per case are peeled off one by one using both hands and put on a machine for packaging food, or the packaging trays are peeled off one by one and collected in a container. I picked them up one by one and put them on a machine for packaging food.

[Problems to be Solved by the Invention] In the prior art, a large space is required for accommodating a container because it is bulky.

Both hands are used in the process of removing the packaging trays one by one.

An object of the present invention is to work in a narrow space with one hand.

[Means for Solving the Problems] In order to achieve the above object, in the packaging tray pick-up device of the present invention, a transmission device is attached to the drive motor 5, and the transfer is carried out with the wheel brush 4 via the transmission device. Interlock belt 2. On the other hand, as a transmission device from the drive motor, the drive shaft is attached to the main shaft pulley 8 and the transfer pulley 10 and the transfer belt lower shaft 3 are attached via the drive belt 11 to connect to the transfer belt. On the other hand, the wheel pulley gear 6 is engaged with the main shaft gear 9 attached to the drive motor, and the coaxial pulley 7. A pulley 13 for a wheel brush is attached to the wheel brush via a belt 12 for the brush.

The frame 14 has a tray 14 at the tray outlet.
When the sensor 15 and the sensor reflection plate 16 for detecting the are attached and the switch 17 of the drive motor is turned on, the drive motor works when the tray is not in the outlet, and the relay 18 which stops the drive motor when the tray is in the outlet is attached. .

[Operation] When several dozen trays are placed on the conveyor belt of the packaging tray take-out device constructed as described above, and the power of the drive motor is turned on, the conveyor pulley is driven from the original shaft pulley by the drive belt. And the lower belt of the conveyor belt rotates, and at the same time, the conveyor belt rotates downward. At the same time, the tray goes down.

On the other hand, the gear for the wheel brush rotates in the opposite direction by the original shaft gear, the coaxial pulley also rotates in the same direction, and the pulley for the wheel brush and the wheel brush rotate by the transmission of the belt for the brush.

[Embodiment] In FIG. 1, a drive motor, a main shaft gear, and a main shaft pulley are integrated by keying.

The wheel brush gear and the coaxial pulley are integrated by keying.

The conveyor pulley and the conveyor belt lower shaft are integrated by keying.

The upper shaft 1 of the conveyor belt and the lower shaft of the conveyor belt are framed and bearings are fitted from both sides to fix them with a bearing cover.

The wheel brush is paired only on one side of the frame body, and is fixed with screws by the bearing cover.

The drive motor is screwed to the frame.

In FIG. 2, several tens of packed trays are vertically stacked on a conveyor belt having an inclination. When the tray falls down by the conveyor belt and the foil brush, the elasticity of the bristles of the foil brush hits the knurling surface 20 at the edge of the tray to push it out and the tray falls.
The light from the sensor 15 is blocked and the drive motor stops.

When one of the trays is taken out, the sensor and the sensor reflector work and the drive motor starts to move. Repeat it one after another.

In FIG. 3, the power source is connected to the sensor. It is connected to the relay and drive motor.

For the flocking of the foil brush, a nylon-based / Teflon-based / synthetic resin material having hardness and elasticity that does not damage the tray is used.

A suitable size of the foil brush is about 80 mm in diameter.

The conveyor belt may be made of rubber or iron.

There is a method of mounting a sensor that senses the weight of the tray itself instead of the sensor that senses the light beam. There is also a method of turning off the limit switch when the tray falls due to its own weight.

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

[0024] The tray does not take up space because it is vertically stacked on the inclined conveyor belt.

It is efficient because the tray can be taken out with only one hand.

Particularly in the case of wrapping mushroom shimeji mushrooms with cultivation, since there is a knurling surface on the upper and outer sides of the tray, it is particularly difficult to remove and can be efficiently removed one by one with the elasticity of the brush of the machine.
