Description

[Detailed description of the invention] <Industrial application field> The present invention relates to a roll brush channel forming machine, and more specifically, it forms a channel used for roll brushes such as conveyor belts, and gives the channel an arbitrary lead angle. This invention relates to a brush channel forming machine.

<Prior art> When molding a channel brush having a gentle spiral shape, such as the channel brush 51 used in the roll brush 50 shown in FIG. 6, brush bristles 53 are planted as shown in FIG. A long channel 52 is once formed into a spiral shape and then stretched in the directions of arrows A and A' to obtain a channel having a desired lead angle.
After stretching and forming the channel 52 in this way, cut the channel 52 to the required length and apply it to the roll brush 5.
I had obtained something that could be attached to 0.

<Problems to be solved by the invention> However, in the conventional forming method as described above, a channel brush is formed into a spiral shape in advance, then stretched with a constant force until a predetermined lead angle is reached, and finally the required length is I had to go through the trouble of cutting it out. This was extremely time-consuming, inefficient, and had poor accuracy.

The reason why such a manufacturing method has been used without circumvention is that there is a means to independently and easily form the channel attached to the roll brush with a certain degree of precision according to the dimensions of the roll brush. Because there were none.

The present invention aims to solve such problems.

<Means for Solving the Problems> Therefore, the present invention consists of a long shaft 1 and an appropriate number of cylindrical bodies that are loosely fitted into the shaft 1 by having their central axis penetrate through the shaft 1. 4, 4', cylindrical bodies 2, 3 with clamping parts disposed on both sides of the series of cylindrical bodies 4, 4' on the shaft 1, and cylindrical bodies 2, 3 with clamping parts provided on one side 3 of the cylindrical bodies with clamping parts. a handle 12;
The cylindrical bodies 2 and 3 with clamping parts are provided with clamping parts 8 and 8' which are capable of detachably holding both ends of the channels of both roll brushes, and the cylinder with clamping parts is provided with the above-mentioned handle. The shaped body 3 is slidable along the longitudinal direction of the shaft 1 and is rotatably fitted onto the shaft 1, preferably loosely, and is connected to the cylindrical body 4' adjacent to the cylindrical body 3 with a clamping portion. To provide a roll brush channel forming machine characterized in that a cylindrical body 3 with a clamping part can be slid in a direction of a cylindrical body 4' by setting a gap 13 between the The aim is to

<Function> In the present invention having the above means, a channel to be formed is arranged between the two cylindrical bodies 2 and 3 with clamping parts, and both ends of the channel are connected to the clamping parts 8,
A handle 12 provided on one side 3 of the cylindrical body with a clamping portion after holding the channel by 8'.
By rotating the channel, a channel with a desired lead angle can be formed. At this time,
In order to obtain a desired lead angle, the cylindrical body 3 with the clamping portion slides in the direction of the cylindrical body 4' by the length that is shortened by curving the channel. Therefore, by selecting the width of the gap 13, it is possible to select the manner of curving, that is, the lead angle, to an arbitrary angle. During the above operation, the channel is wound around the surfaces of the series of cylindrical bodies 4, 4' between the two cylindrical bodies 2, 3 with clamping parts that hold the channel, and the channel is curved. This cylindrical body 4, 4'
are each rotatably attached to the shaft 1, so that they rotate individually according to the twist of the channel during channel forming. Therefore, the channel is
It is twisted smoothly and formed with high precision without stress being concentrated locally.

After molding, the clamping parts 8, 8' are released, and the completed channel is removed from the molding machine to complete the work.

As described above, in the present invention, when forming a channel, the lead angle can be selected by selecting the gap 13, and the cylindrical bodies 4, 4' along which the channel runs can rotate independently according to the twist of the channel, making unnecessary Its effect is to eliminate the stress concentration and to set the lead angle with high precision.

Once completed, the channel can be sold as a separate product or attached to a roll brush where necessary. The present invention has made it possible to form such a channel.

FIG. 1 shows an embodiment of the present invention. An appropriate number of cylindrical bodies 2, 3, 4,
4' is attached rotatably. That is, each cylindrical body 2, 3, 4, 4' is provided with a through hole that is approximately the same as or somewhat larger in diameter than the shaft 1 from the center of the bottom surface to the center of the other bottom surface. axis 1
is passed. The cylindrical bodies 2, 3, 4, 4' have the same outer diameter. This corresponds to the diameter of the roll to which the channel brush 5 formed by this device is to be attached. Several cylindrical bodies 2, 3, 4, 4' attached to the shaft 1 as described above
The cylindrical bodies 2 are arranged so that their circumferential surfaces collectively form one circumferential surface, and one of the cylindrical bodies 2 disposed at both ends is fixed to the shaft 1 (so that it cannot rotate). Become. Further, plate-like bodies 6, 6' are placed at appropriate positions on the circumferential surfaces of the cylindrical bodies 2, 3 disposed at both ends.
will be provided. The plate-like bodies 6, 6' are the cylindrical bodies 2, 3
It is fixed so that its plate surface is in contact with the circumferential surface of. Clamping parts 8, 8' for clamping the ends of the channel 7 of the channel brush 5 are provided on the plate-shaped bodies 6, 6'.
In this embodiment, a chuck structure as shown below is used, but any structure that allows the channel to be removed after molding may be used, and the channel 7 may be fixed by other methods instead of the chuck structure. That is, cylindrical small protrusions 9, 9' are provided on the plate surfaces of the plate-like bodies 6, 6', and the small discs 10, 10' are pivoted at appropriate intervals near the small protrusions 9, 9'. Stop. The small discs 10, 10' are fixed to the shafts so as to be rotatable about eccentric positions, and are provided with gripping members 11, 11' for applying force when rotating.

As shown in FIG. 2, both ends of the channel 7 of the channel brush 5 are sandwiched between the circumferential surfaces of the small protrusions 9, 9' and the small disks 10, 10', and the gripping members 11,
Turn 11'. As a result, the long axis of the small disks 10, 10', which are eccentrically fixed, is set to the channel 7.
Tighten it to make sure it is fixed.

Further, in this embodiment, a handle 12 is provided on the rotatable cylindrical body 3 disposed at the end for rotation thereof. This handle may have another shape. By turning this handle 12, the fixed channel brush 5 is twisted. Although the channel brush 5 is linear, the width in the longitudinal direction is shortened by bending it by the above-mentioned means. Considering this change in length, the cylindrical bodies 2,
A gap 13 is provided at at least one location between 3, 4, and 4'. Conversely, the lead angle of the channel brush 5 can be determined by the width of this gap 13.

FIG. 3 shows another embodiment. In order to determine the lead angle of the channel brush 5, a ring-shaped body 14 may be fixed to the gap 13 of the shaft 1. That is,
The cylindrical body 3 equipped with the channel holding part 8' slides and hits the ring-shaped body 14, so that the ring-shaped body 14
The sliding width of the channel is determined by the fixed position of the channel. This is how the lead angle of the channel brush 5 is determined. Further, in order to accurately determine the position before sliding, a similar ring-shaped body 15 may be fixed on one circumference of the outer axis of the rotatable cylindrical body 3 disposed at the end.

The length of the channel also varies depending on the product, but the distance between the cylindrical bodies 2 and 3 at both ends where the channel holding parts 8' and 8 are provided may be changed. Just change the number of bodies 4 and 4' to accommodate this.

Alternatively, as shown in FIG. 4, it may be implemented as a universal roll brush channel forming machine having cylindrical bodies each having a different diameter to match the diameter of the roll to which the channel brush is attached. This consists of each channel forming machine 1 with cylindrical bodies of different diameters.
6, 16', 16'' are arranged in parallel, each axis 1, 1',
1'' both ends are fixed to a common support stand 17.

FIG. 5 shows another embodiment of a cylindrical body 4, 4' which can be inserted between cylindrical bodies 2, 3 provided with clamping parts 8, 8'. In this case, a guide holder is provided at an appropriate position on the circumferential surface of the cylindrical bodies 4, 4' where the channel comes into contact when the channel brush is fixed to the clamping parts 8, 8'. The guide holder is for ensuring that the other cylindrical bodies 4, 4' send a channel in the circumferential direction when the cylindrical body 3 provided with the clamping portion 8' is rotated. For more information,
Protrusions 18, 18' are formed at suitable positions on the circumferential surface of each cylindrical body 4, 4' at the portions where the channels come into contact, with appropriate intervals so as to sandwich the channels.

<Effects of the invention> Even women and non-skilled workers can easily and quickly shape a straight channel brush, which has been preformed to a predetermined length, into a gentle spiral brush without requiring any force. I can do it. Moreover, the lead angle can be determined freely and is highly accurate. Furthermore, since the above-mentioned processing is a simple operation and does not require complicated steps, the cost can be significantly reduced.
