Description

[Detailed description of the invention] Industrial application field This invention forms briquettes from grass etc. supplied to the roll forming section, and cuts the briquettes into accurate dimensions during the delivery process. The present invention relates to a cutting device in a roll forming machine that can be used in a roll forming machine.

BACKGROUND TECHNOLOGY Conventionally, in a roll forming machine that compresses grass etc. supplied to a roll forming section into briquettes and cuts the briquettes that are fed out to one side of the machine body during the feeding process, the briquettes are arranged at intervals of the cutting length of the briquettes. It is known that the briquettes being fed are cut by moving a plurality of blades provided at substantially the same speed as the briquette feeding speed.

Problems to be Solved by the Present Invention However, in a device in which a plurality of cutters are moved at approximately the same speed as the feed speed of the briquette, for example, as shown in FIG. The endless belt a must be rotated at approximately the same speed as the briquette delivery speed. This makes the device complicated and large, and
Since the feeding speed of the briquettes varies depending on the amount of grass supplied, etc., it is difficult to properly adjust the rotational speed of the endless belt a to achieve work precision.

The present invention was devised to solve these problems in view of the above-mentioned actual situation, and although the briquettes formed in the roll forming section are cut during the process of sending them to one side of the machine,
Cutting in a roll forming machine with a simple structure that allows accurate cutting even if the briquette feed speed changes by simply swinging the cutter that is rotationally driven when the briquette is fed a predetermined length. The purpose is to provide equipment.

Means for Solving the Problems In order to achieve the above object, the technical means taken by the present invention are to form grass etc. fed to the roll forming section into briquettes, and to feed the briquettes to one side of the machine body. In a roll forming machine that cuts briquettes into a predetermined length during the feeding process, a cutter that is rotatably driven with an axis parallel to the feeding direction is provided in the feeding path of the briquette, and the cutter is swingably driven. It is characterized by being configured to be movable in the briquette delivery direction.

Function of the invention Next, the function of the invention configured as described above will be explained. When grass or the like is supplied to the roll forming section of the roll forming machine, the compressed grass or the like is formed into briquettes and sent out to one side of the machine body. Then,
When the briquettes are fed out a predetermined length, by swinging the cutter provided on the feeding path, the briquettes can be cut by the cutter that is driven to rotate about an axis parallel to the feeding direction of the briquettes. The cutter, which is movable in the feeding direction of the briquettes, bites into the briquettes and cuts the briquettes while moving with the briquettes being fed out, so that even if the feeding speed of the briquettes changes, the cutters can be cut into accurate dimensions.

Embodiment To explain the configuration of the present invention with reference to an embodiment shown in the drawings, reference numeral 1 is a roll forming machine connected to a tractor or the like. A pick-up device 2 is provided for picking up. A roll forming section 4 consisting of a plurality of compression rolls 3, 3, . and compression rolls 3, 3
It is compressed and formed into a cylindrical briquette a.

One end of the compression roll 3 is pivotally supported by a gear case 7, and the other end is pivotally supported by a rotatable bearing disc 9 that is biased in one direction by springs 8, 8... When the briquette a is hard compressed and the frictional force acting on the compression roll 3 becomes large, the bearing disc 9 rotates, and the briquette a is opened into the bearing disc 9 by the feeding action of the compression roll 3 which is in the twisted mounting position. It is sent out from the guide hole 10 to the side of the fuselage.
Reference numeral 11 is a guide cylinder that supports the sent-out briquette a, and the lower half 11a can be opened and closed downward. Reference numeral 12 denotes a sensor provided at the tip of the guide tube 11. When the briquette a fed into the guide tube 11 pushes the sensor 12, the support shaft 13
The sensor 12, which rotates around , operates the cutting timing clutch 15 via the rod 14, and in conjunction with this, the cutter 16 provided on the feed path of the briquette a moves up and down to cut the briquette a. That is, it is supported by a support shaft 17, and the spring 1
The swinging arm 19 is biased downward at 8.
A cutter 16 is attached to the tip of the cutter 16, and a wire 20 connecting the swing arm 19 and the arm 6a of the rear packer 6 is suspended around a roller 22 attached to a rod 21 that can slide left and right. The swing of the arm 6a causes the wire 20 to slide only the rod 21 left and right, and the actuation of the cutting timing clutch 15 moves the rod 21 to the wire 2.
When fixed at the position where the roller 22 protrudes on the 0 side,
The swing arm 19 is moved upward against the bias of the spring 18. A boss 24 rotatably driven via a drive chain 23 is pivotally supported at the tip of the swing arm 19, and a cutter 16 attached to a rotating shaft 25 spline-fitted to the boss 24 feeds the briquette a. It rotates around an axis parallel to the direction. Then, when the cutter 16 moves upward and its upper end bites into the briquette a,
As the briquettes a are fed out, the spline-fitted rotary shaft 25 slides and the cutter 16 moves in the direction of feeding the briquettes a. 26 is a spring that returns the cutter 16 that has been moved in the feeding direction, and 27 is a roller that supports the bearing disc 9. Note that the cutter 16 rotates in the opposite direction to the direction of rotation of the briquette a, and is configured so that it can only move upward to a point slightly above its center.

FIG. 7 shows another embodiment, in which an initial pressing device 28 is provided near the outer periphery of the lower end of the rotating cutter 16 to apply a pressing force in the feeding direction of the briquette a, so that the cutter 16 moves upward. When cutting the briquette a, only the upper end side of the cutter 16 is prevented from being pushed to one side by the fed briquette a, so that the cutter 16 moves smoothly in the feeding direction. That is, 29 is a rotatable mounting arm pivotally connected to the rotation shaft 25, 30 is a boss having a notch fixed to the tip of the mounting arm 29, and 31 is a shaft passing through the boss 30. mounting bracket 3
2, the roller 33 that comes into contact with the cutter 16 is connected to the pin 3.
It is rotatably mounted via 4. 35 is a roll pin that always holds the roller 33 in the tangential direction to the rotation direction of the cutter 16 by a notch in the boss 30, 36 is a spring that presses the roller 33 against the cutter 16, 37 is a washer, and 38 is a cotter pin. .

In the above configuration, when the roll forming machine 1 is connected to a tractor or the like and travels through a field where grass etc. are scattered, the grass collected by the pick-up device 2 is transferred to the roll forming section 4 by the front packer 5 and rear packer 6. The briquettes are supplied to a cylindrical briquette a and formed into cylindrical briquettes a. The formed briquette a is sent out into the guide tube 11 through the guide hole 10 by the sending action of the compression roll 3 in the twisted mounting position, and when the tip abuts on the sensor 12
rotates around the support shaft 13, actuates the cutting timing clutch 15, and fixes the rod 21, so that the wire 20 moves the swinging arm 19 upward, and the cutter 16 attached to the tip of the swinging arm 19 moves upward. The outer periphery of the upper end side of the briquette a bites into the briquette a and cutting begins. When the further fed briquette a pushes out the outer periphery of the upper end of the cutter 16, the spline-fitted rotary shaft 25 slides and the cutter 1
Since the briquette 6 moves together with the briquette a, even if the feeding speed of the briquette a changes, cutting can be performed with high precision.

Although the cutter 16 is designed to move upward only to a point slightly above the center of the briquette a, since the briquette a rotates in the opposite direction to the cutter 16, the briquette can be cut reliably. Furthermore, since the cutter 16 moves upward only to the vicinity of the center of the briquette a, the amount of movement of the cutter 16 in the feeding direction of the briquette a is kept to the minimum necessary, and the cutter movement hole provided in the guide tube 11 can also be made smaller. Therefore, the briquette a can be supported reliably, and the cutter 16 can also support the briquette a.
It also does not unnecessarily interfere with extrusion.

Further, in the case where the initial pressing device 28 is provided, the cutter 16 is not pushed to one side and moves more smoothly, so that cutting accuracy can be further improved.

Effects of the Invention In short, the present invention provides a roll forming machine that forms grass, etc. supplied to the roll forming section into briquettes, and cuts the briquettes into predetermined lengths during the sending process to one side of the machine body. A cutter rotatably driven by an axis parallel to the feeding direction of the briquette is provided in the feeding path of the briquette, and the cutter is configured to be movable in the feeding direction of the briquette, so that the cutter does not bite into the briquette. The cutter is
Since the briquettes can be cut while moving in the feeding direction with the briquettes being fed out, it is possible to cut the briquettes accurately by simply moving the cutter up and down when the briquettes reach a predetermined length, without using multiple blades as in the conventional method. , Even if the feeding speed of the briquette changes depending on the amount of grass supplied, etc., the briquette can always be cut to an accurate length, etc.
This has extremely useful practical effects.
