Description

Rotating ring type wrapping apparatus

The present invention relates to a rotary ring-type wrapping apparatus, and more particularly, to a rotary ring-type wrapping apparatus capable of determining whether plastic wrap is broken in a rotary ring-type wrapping apparatus through a generator and a wireless transmitter.

A bale refers to a bundle of grasses used as winter forage for ruminant cattle, and a baler collects grasses scattered in the open field, compresses them into a cylindrical (or box-shaped) bale, and puts the outside of the bundle into a net to maintain the shape. It refers to agricultural machinery that binds together.

Although these balers independently run on the field and perform bale production, they are mainly towed by a tractor and work with the power provided by the tractor.

On the other hand, there is a lot of demand for fermented rice straw as succulent feed in livestock farms in Korea. In order to store and use it stably, a large silo facility is required, which is a burden on the farmers. It can be stored in large quantities around and can be used as forage at any time.

To this end, a baler additionally equipped with a wrapping device for performing a plastic wrap packaging operation is used.

Looking at the plastic wrap packaging process of the lapping device through FIGS. 1 and 2, the bale on which the net binding is completed by the pre-treatment of the baler is rotated with the roller 246 in a roll-type plastic wrap (hereinafter referred to as a 'wrap roll'). ) mounted on the rotating arm 320 of FIG. 1 or the rotating ring 10a of FIG. 2 rotates around the bale several times, the plastic wrap drawn out from the wrap roll wraps the bale, so that the bale is packaged.

However, in order to increase the preservation of the bale, it is necessary to apply a certain tension to the plastic wrap and wrap the bale to tighten it. The plastic wrap is also broken.

In addition, there is a problem in that it is difficult to grasp the fracture of the plastic wrap because the plastic wrap packaging operation is generally performed at the rear of the baler or tractor.

3, 4 and 5, the present invention is a rotating part 10 for rotating the bale (B), the mounting part 20 on which the wrap roll (W) is mounted, the bale (B) disposed on the rotating part (10) ) as a center, the turning part 30 for turning (θ) the mounting part 20, the tension part 40 for adjusting the tension of the plastic wrap W1 drawn out from the wrap roll W, and the plastic wrap drawing out It is made to include a sensor unit 50 for detecting whether the fracture of the (W1), the fracture prevention means 60 is optionally provided here.

When describing the specific contents of the present invention based on each component, first, the rotating unit 10 includes a plurality of rollers 11 and a holder 13 . At least one of the plurality of rollers 11 is rotated by a hydraulic motor operated by power provided by the tractor, and the bale B is rotated by the rotation of the corresponding roller 11 .

The holder 13 temporarily holds the end portion W2 of the plastic wrap W1 at the beginning of packaging so that the plastic wrap W1 is wound around the bale B, while a cutter is provided to the end portion W2 after the packaging is completed. ), and performs the corresponding functions in a way that stands up or is inverted by the control signal of the control box.

The cradle 20 includes a cradle 21 on which the wrap roll W is rotatably mounted, and the lap roll W is detachably attached to/from the cradle 21 through the manual operation of a normal operator.

The turning part 30 supports the rotary ring 31 to which the holder 21 is fixed to the inner circumferential surface, the driven gear 32 formed on the outer circumferential surface of the rotary ring 31, and the rotary ring 31 while supporting the driven It consists of a plurality of driving gear units 33 coupled to the gear 32 , and a hydraulic motor for rotating the driving gear unit 33 by receiving power from a tractor.

A pair of cradles 21 is usually fixed at corresponding points on the rotating ring 31 in order to increase the efficiency of the packaging operation.

The tension part 40 includes the brake roller 41 and the extension roller 42 disposed adjacent to the holder 21, and the brake roller 41 and the extension roller 42 so that the rollers 41 and 42 are interlocked. The gear set 43, the brake roller 41 and the extension roller 42 provided on the rotating shafts 411 and 421 are rotatably fixed and themselves also rotatably on the rotating ring 31 through the hinge member 441. The holding plate 44 is fixed, and the brake roller 41 is made of a first pressing means 45 to be in close contact with the outer peripheral surface of the wrap roll (W).

The plastic wrap W1 drawn out from the wrap roll W of the holder 21 wraps the bale B after winding the brake roller 41 and the extension roller 42 in a zigzag shape. And a predetermined tension is generated in the plastic wrap W1 by the rotation speed of the rotating ring 31 and the bale B can be tightly packed.

On the other hand, when each roller 41 , 42 is independently provided to rotate freely, acceleration and deceleration of each roller 41 , 42 at the packaging start or end stage may be different for various reasons, and due to this speed difference, If the pulling-out speed of the plastic wrap W1 at each of the rollers 41 and 42 is different, a jam may occur.

The gear set 43 prevents a jam by causing the brake roller 41 and the extension roller 42 to interlock to decelerate or accelerate at the same speed.

In addition, the wrap roll W is also provided to be freely rotated on the holder 21 like the rollers 41 and 42, but excessive unwinding may cause jam at the packaging start or end stage. Accordingly, it is preferable that the brake roller 41 be disposed in close contact with the outer circumferential surface of the wrap roll W to prevent excessive loosening.

However, since the radius of the wrap roll W is gradually reduced due to the exhaustion of the plastic wrap W1, as shown in FIG. 6, when the first pressing means 45 applies a rotational force to the holding plate 44, the brake roller ( 41) continues to be in close contact even when the wrap roll W is exhausted.

Specifically, in the first pressing means 45, the rod 451 is fixed to the holding plate 44 in a state where one end is fixed to the rotating ring 31, and the holding plate 44 is provided by an elastic member provided therein. ) is rotated (β) around the hinge member 441, it is possible to obtain the rotational force necessary for maintaining close contact.

The sensor unit 50 includes a generator 51 coupled to the shaft 411 of the brake roller 41 and a wireless transmitter 52 electrically connected to the generator 51 .

When the rotary shaft 411 rotates due to the withdrawal of the plastic wrap W1, electricity is generated by the generator 51, and the wireless transmitter 52 transmits a predetermined signal through the generated electricity. And the control box is provided with a wireless communication module and an alarm means for indicating whether the signal is received.

Therefore, when the rotation of the rotating shaft 411 is stopped due to the fracture of the plastic wrap (W1), the application of electricity is stopped and the signal transmission is also stopped together, so that the signal transmission stop is displayed on the alarm means, the operator breaks the plastic wrap (W1) can be recognized

As mentioned above, the fracture of the plastic wrap W1 is caused by the sharp stems of grasses protruding out of the net. And the net usually surrounds only the circumferential surface (B1) of the bale (B), and due to various causes, there are many cases in which scraps of grass are generated at the end of the net in the bale (B) production section. For this reason, the plastic wrap (W1) fracture occurs mainly in the process of wrapping the edge (B3) of the veil (B) corresponding to the end of the net.

Therefore, if the tension of the plastic wrap W1 is somewhat reduced when wrapping the corner B3, the occurrence of fracture can be suppressed, and thus, in the present invention, as shown in FIG. (B) a fracture preventing means 60 for temporarily reducing the tension immediately before wrapping the edge (B3) may be additionally provided.

Specifically, the fracture preventing means 60 is disposed on the orbital m of the holding plate 44, a plurality of limit switches 61 disposed adjacent to the corner B3, the holding plate 44 disposed on and a terminal (not shown) connected to the generator 51 , a second pressing means 62 provided on the holding plate 44 , and a plastic wrap W1 provided on the rod of the second pressing means 62 and drawn out ) consists of a pressure roller 63 for pushing outward.

The pressing roller 63 has the same configuration as the first pressing means 45 , but an electromagnet is added, and the electromagnet is connected to the generator 51 .

Therefore, when the terminal touches the limit switch 61 during the turning (θ) process of the holding plate 44, the electricity produced by the generator 51 is applied to the electromagnet, which is produced by the magnetic force of the electromagnet. 2 As the rod of the pressing means 62 moves backward, the pushing force of the pressing roller 63 is reduced and the tension of the plastic wrap W1 is relieved, and the fracture of the plastic wrap W1 surrounding the corner B3 is reduced. will be suppressed

Although preferred embodiments of the present invention have been described above, the scope of the present invention is not limited thereto, and it should be understood that the scope of the present invention extends to a range substantially equivalent to the embodiment of the present invention, Various modifications may be made by those of ordinary skill in the art to which the invention pertains without departing from the spirit of the invention.
