Abstract

The invention relates to the forest and woodworking industry. The aim of the invention is to improve the reliability of the clamping package of lumber of various sizes and reduce energy consumption. The feeding device consists of a frame on which the feeding chain conveyor is mounted. On the chain 4 there are fixed stops 5 with a curved groove 6. Through the groove 6, fingers 7 of the movable stop 8 are missed. Its lower end is equipped with a shuttle 9 in the form of a lever. The shuttle 9 is hingedly mounted on the screw 10. A working guide is installed parallel to the frame and at the level of chain 4. It consists of separate sections, each of which has an upper 13 and lower 14 parts. Sections are spring loaded. On the moving together with the chain 4, the stop 5 is placed on the package of blanks 16. After the hook 9 has entered the guide, the stop 8 in the groove 6 rotates and crimps the bag 16. In this position, the bag slides over the saws and is cut into pieces. 3 il.

The invention relates to the forest and wood processing industry and can be used when cutting parts of dotted lengths, such as parts of the parquet floor.

The aim of the invention is to improve the reliability of clamping a package of lumber of various sizes and reduce energy costs.

Figure 1 shows the feeder, obti view; figure 2 - node I in figure 1; on fig.Z - section aa in figure 2.

The woodworking machine feed unit consists of frame 1, on which the sprockets 2 and 3 are mounted with roller-roller chains 4 tensioned on them, ng of which are uniformly along the length, fixedly relative to chain 4, additional fixed stops 5 are installed, made with a curved groove 6, through which the leading fingers 7 of the clamping movable stop 8 are passed, the lower end of which is provided with the shuttle 9 in the form of a lever mounted on the stop for 8 s. pomoshch1) Yu screws 10 and 11, and under the screw II in the shuttle 9 is made a groove 12. The shuttle 9 in the form of a lever is pivotally mounted on the screw 10.

On frame 1, parallel to i, at the level of chain 4, a working runner is installed, made of separate sections, each of which has an upper 13 and lower 14 parts. The sections are spring-loaded using springs 15. This allows the clamping force of the batch of blanks in the sawing zone to be adjusted in size by pressing the springs that act on the individual sections of the upper and lower parts of the guides 13 and 14. As the shuttle 9 is pulled between sections The top and bottom parts of the guide are compressed by the springs. The shuttle 9, moving into the slot, senses the spring position on the horizontal slot portion.

The device works as follows.

Moving together with the chain 4, the stop 5, the package 16 of blanks is laid. At this time, the movable stop 8 is in the folded down position (Fig. 1). Upon further movement of the chain, 4 4ej HOK 9 enters the direction, turns the support 8 in the groove 6 until the bag 16 is compressed. In such a position, the bag slides over the saws and sprays into pieces. When the shuttle 9 comes out of its direction, the stop 8 leans back, turning into the groove 6, and releases the bag 16, taking the initial position.

The proposed feeder allows you to increase productivity and improve the quality of cutting out the removable parts, eliminating the mowers and chips, since the workpieces are clamped automatically when they are pulled over.
