Abstract

PURPOSE:To carry out automatic binding by performing binding with a binding mechanism when passage of conveyed materials for binding is sensed with a sensor, simultaneously stopping a conveyor, starting conveyance after completing the binding and then discharging the bound materials to the outside of a machine. CONSTITUTION:When passage of materials which are placed on a conveyor 3 and conveyed for binding is sensed with a sensor 26, bindging operation is carried out with a binding mechanism and the conveyor is simultaneously and automatically stopped. After completing the binding operation, the conveyor 3 is then automatically redriven to discharge the bound materials for binding to the outside of the machine while placing and conveying the bound materials for binding thereon. Thereby, automatic binding is carried out in a state with hardly any fear of damage without applying excessive force to the materials for binding.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an agricultural binding device for binding vegetables, flowers and trees, and the like.

[Conventional technology]

Conventionally, when bundling vegetables, flowers, and trees in fixed quantities, it has been common to manually bind them using, for example, synthetic resin thin film tape or string.

[Problem to be solved by the invention]

However, if the above-mentioned manual work is carried out manually, the labor burden on the operator becomes large when the amount of processing is large, so automation of this type of work has been desired.

Therefore, it has been considered to perform the above-mentioned tying operation using a well-known stem culm tying device installed in a combine harvester or the like. However, the above-mentioned stem culm binding device uses a waste straw transport chain to transport and supply the waste straw discharged from the threshing device almost continuously as the machine runs, to the starting end of the tying device, and the packer is constantly oscillated by a crank. so that it is pushed into the binding space. In addition, in the bundling space, the scraped straw is caught by a sensing door and compressed and focused, and when the focusing pressure increases to a predetermined pressure, the sensing door senses the swing due to the pressure, and the one-turn clutch is activated. After the tying is carried out, it is discharged outside the machine by the discharge arm. Therefore, when vegetables, flowers, etc. are tied using this stem culm tying device, they are subjected to strong pressure when they are pulled into the tying space. There is a greater risk of damage due to the discharging arm, and there is also a greater risk of breakage due to the strong discharging force of the discharging arm.

An object of the present invention is to enable automatic bundling of vegetables and the like by rationally improving the structure.

[Means to solve the problem]

The present invention is characterized by: a conveyance device that places and transfers objects to be bound that are intermittently supplied in fixed quantities; a sensor that detects when objects to be bound have passed a predetermined position during conveyance of the conveyance device; A binding mechanism that binds the objects to be bundled while they are placed in accordance with the detection operation of the sensor; and a binding mechanism that automatically stops the driving of the conveying device in accordance with the detection operation of the sensor; The present invention further includes a switching means for automatically restarting driving of the conveying device.

[Function] When the passage of the object to be bound, which is placed on the transport device and transported, is detected by the sensor, the binding mechanism performs the binding operation, and at the same time, the transport device automatically stops. When the binding operation is completed, the conveying device is automatically restarted, and the bound objects are placed and conveyed while being discharged from the machine.

〔Effect of the invention〕

Therefore, according to the present invention, the objects to be bound are transported in a state where they are consistently placed from the transport start end to the end end, and the transport is temporarily stopped during the binding operation, so that the objects cannot be carried into the binding space and Automatic binding can now be performed without applying excessive force to the objects to be bound and with little risk of damage during discharge from the binding space to the outside of the machine and during the binding operation.
