Description

[Detailed description of the invention] The present invention relates to an automatic serging machine for flat bars, and its purpose is to easily and automatically comb the flat bar without changing the feed axis or rolling. It is.

Conventionally, when flat bars are subjected to rolling or other processing, it is necessary to attach the ends of each bar to ensure and facilitate feeding between the processing rollers.

For this reason, when the flat bar on the supply table is fed to the applicator roller placed opposite the tip of the supply table to perform the desired application, the flat bar is first placed on the outer peripheral surface of the applicator roller and in parallel in the axial direction. First, the flat bar is inserted into a predetermined groove among the many opening grooves, and the flat bar is pressed in one direction, and then the bar position is rotated 90 degrees and moved to the next groove position of the opening roller. Then kiss from the other direction and repeat these two steps as 1.
The desired kiss is repeated two or more times. Therefore, the flat bar is rotated for each step,
Since it has to be moved manually according to the selected groove, it takes time to attach the bar, and it is difficult to turn and move a long or heavy flat bar. This makes it impossible to perform the desired kiss, and the kiss must be performed by fusing or the like.

In view of this, the present invention has been developed to allow kissing to be performed simply and reliably without rotating or moving the flat bar, and will be described below based on the illustrated embodiment.

In the figure, reference numeral 1 denotes the main body truck of the automatic gating machine, and this main body truck 1 is equipped with a prime mover M and a speed reducer G. Thereby, two sets are installed on the truck, namely, a vertical type and a horizontal type. A rail is arranged to drive the rollers 3 and 4, and has wheels W and W at the bottom thereof, and is arranged in a direction perpendicular to the longitudinal axis of the flat bar that is repeatedly fed out in a moving direction, that is, in a direction in which the main body of the cutting machine moves. It is possible to run freely on R. This rail R may be omitted and the wheels may run directly on the floor surface. This reciprocating movement of the main body truck is performed by the cylinder 2, but other methods may be used. The running range of this trolley is defined as between the vertical opening roller 3 and the horizontal opening roller 4 which are installed in parallel on the top of the main body carriage.
The horizontal opening rollers 4 are disposed at the front position when the main body truck moves forward, that is, as shown in FIG. 1, facing each other vertically. Attachment grooves 4a are provided in parallel. Then, any groove selected according to the size of the flat bar from the leftmost groove to the rightmost groove of this mouthing groove and the right side of this vertical mouthing roller (in Fig. 1) ) The main body carriage is made to travel back and forth while changing the distance between the horizontal rollers 4.

The above-mentioned horizontal type mouthing rollers 4 are a pair of upper and lower rollers, arranged parallel to each other, and driven by a speed reducer G in synchronization with opposite directions. A large number of opening grooves 4a having different groove widths and depths are provided in parallel with each other depending on the size of the flat bar, that is, the width and thickness. The opening rollers 4 are provided in such a manner that they are aligned. This horizontal type gating roller 4 is driven by a motor M via a speed reducer G to drive gears G ₁ and G ₂ provided at the shaft ends of the vertically opposing gating rollers 4 and 4. Gears driven by reducer G
A gear G ₁ is meshed with G ₃ , and a gear G ₂ is meshed with this gear G ₁ to drive the rollers 4 , 4 for both ends synchronously in opposite directions.

The upper spouting roller 4 is rotatably supported by bearings (not shown) that are movable on stays 1a, 1a that are set up parallel to the main body carriage, and mounted on the top of the stay. The rollers can be adjusted up and down using a handle H, so that the distance between the upper and lower rollers can be adjusted to match the size of the flat bar. In addition, two vertical spouting rollers 3 are supported in parallel with their axes oriented vertically.
The outer circumferential surface of the flat bar is made flat so that the long sides of the flat bar are held and pressed together, and the flat bar is driven synchronously in opposite directions by the speed reducer G. One of the rollers is movable by a handle H, and the distance between the rollers is adjustable according to the thickness of the flat bar.

When a flat bar is pressed using the apparatus configured as described above, the main body carriage is placed adjacent to an extruder (not shown) that extrudes a desired flat bar in a manner that allows it to move forward and backward, and Select one of the grooves to be opened according to the size and shape of the bar, and insert only the length to ensure that the tip of the flat bar that comes out and retracts with the extruder into the selected groove at the position where the main body carriage moves forward and stops. Do what you want. At this time, since the horizontal kissing roll is being rotated, it kisses the tip of the flat bar in the width direction. Then, the main body carriage is advanced so that the vertical kissing rollers 3, 3 coincide with this flat bar extrusion position, the flat bar is inserted into the gap between the rollers 3, 3, and the bar is kissed in the thickness direction. This operation is performed once or twice or more alternately between the vertical and horizontal kissing rollers to perform the desired kissing. When repeating this operation, the main cart is moved back and forth and always at a constant position. The flat bar that appears and retracts is pressed in the vertical and horizontal directions to perform the kiss, but the flat bar does not need to be rotated.

According to the present invention, the main body carriage, which is provided with two sets of rollers that are driven in parallel and that clamp the flat bar in the horizontal and vertical directions, respectively, is moved in a direction perpendicular to the longitudinal axis of the flat bar being pushed out. It is provided so that it can freely travel back and forth, and the vertical and horizontal opening rollers on the main body carriage are alternately positioned at the flat bar position by moving the carriage, so the flat bar can be rotated. You can easily perform the desired kissing by simply moving it in and out at the same position without moving it, and even if the flat bar size is different, the axes of the mouthing grooves of each size on the rollers are aligned, so the main body trolley can be easily attached. There is an advantage that an accurate kiss can be performed by only slightly regulating the forward and backward movement position of the
