In the related art, rod type sectional materials belong to one part which is most commonly used in equipment, in the batch production process, a plurality of rods are sequentially positioned and fed by adopting a conveying bin with a fixed size, and the conveying bin with the fixed size cannot be compatible with the rods with different lengths. And because the bar needs to be positioned during subsequent production, a manipulator or other processing tools can rapidly process or move the bar, and when the conveying bin with the lateral side not limited is used, namely the conveying bin with the left side not limited conveys the bar, the positioning of the bar, namely the subsequent processing efficiency, is influenced. Therefore, there is a need for a feeding device that is compatible with a variety of bar stock length dimensions.

Therefore, the embodiment provides a bar feeding device, and the width-adjustable conveying bin is constructed by the bar feeding device through the first side limiting part and the second side limiting part, so that bars with various length sizes can be accommodated.

The inventive concept of the present application is further illustrated below with reference to some specific embodiments.

Specifically, the frame 100 is a supporting member for supporting the bar 1, the first side limiting member 200, and the second side limiting member 300. The frame 100 may be a frame structure formed by welding a plurality of channel steels or angle steels, and a layer of steel plate is welded on the top of the frame structure and forms a certain angle with the horizontal plane. The top surface of the steel plate is the conveying surface A. When the frame 100 is placed on the ground, the conveying surface a may have a small angle with the horizontal plane, so that the bar 1 may roll down along the conveying surface a when the bar 1 is placed on the conveying surface a. A batch of a plurality of bars 1 roll off and are fed on a conveying surface A along the conveying surface A in sequence. It will be readily appreciated that the conveying surface a may also be arranged on a horizontal plane, in which case the feeding may be accomplished by pushing the bars 1 from behind the plurality of bars 1 by means of a feeding mechanism, such as a push rod or the like.

Referring to fig. 1, the first side limiting member 200 and the second side limiting member 300 are respectively located at two sides of the conveying surface a, so as to define a feeding channel together with the conveying surface a. Referring to fig. 1, a plurality of bars 1 are sequentially arranged in a feeding passage. The bar stock 1 is sequentially fed in the feeding channel. The width of this material loading passageway is adjustable, and first side locating part 200 and second side locating part 300 can follow the width direction removal of material loading passageway promptly, and to bar 1 of different length, both sides terminal surface that bar 1 was drawn close to all can be followed bar 1 to first side locating part 200 and second side locating part 300 to make bar 1 loading attachment of this embodiment can be compatible not unidimensional bar 1.

at least two rotating rods 410, wherein one end of each rotating rod 410 is hinged to the first side limiting piece 200, the other end of each rotating rod 410 is hinged to the rack 100, and the at least two rotating rods 410 are arranged in parallel and at intervals along the length direction of the first side limiting piece 200;

wherein at least a portion of the rotating rod 410 is parallel to the conveying plane a.

Specifically, the first lateral limiting member 200 completes the adjustment in the width direction of the feeding channel through the first lateral adjusting assembly 400. Referring to fig. 2, in the present embodiment, the parallel four-bar linkage is constructed by the rotating rod 410, the frame 100, and the first side limiting member 200 to move the first side limiting member 200. The parallel four-bar linkage structure is stable and reliable. When the spatial position of the first side limiting part 200 needs to be adjusted, the parallel four-bar linkage structure rotates one of the rotating rods 410, and the other rotating rods 410 can synchronously swing, so that the adjustment is more convenient and faster. It should be noted that the first lateral limiting member 200 can also be driven by a linear driver to move in the width direction.

Referring to fig. 1 and fig. 2, in the present embodiment, at least a portion of the rotating rod 410 is parallel to the conveying surface a, that is, when the rotating rod 410 swings, the first side limiting member 200 can move on a plane parallel to the conveying surface a. Thus, when the width of the feeding channel is adjusted, the first lateral limiting part 200 can be always in contact with the end surface of the bar stock 1, so that the bar stock 1 is positioned. The situation that the first side limiting part 200 leaves the bar stock 1 in the normal direction of the conveying surface A to cause the bar stock 1 to move left and right on the conveying surface A is avoided.

It is worth mentioning that the clamping member 420 may also be configured as a clip or the like.

The adjustment member is coupled to the clamping member 420 such that the rotating lever 410 is stationary relative to the clamping member 420. That is, the adjusting member may be a bolt, and the bolt is inserted into the free end 423 and is threadedly connected to the fixed end 421. The distance between the free end 423 and the fixed end 421 can be adjusted by screwing the bolt, so that the free end 423 can clamp the rotating rod 410 or loosen the rotating rod 410.

In an embodiment, the second side limiting member 300 can also move in the width direction of the feeding channel, and the second side adjusting member is connected to the rack 100 and the second side limiting member 300, and the second side adjusting member and the first side adjusting member 400 are symmetrically disposed. It is to be understood that the structure of the second lateral adjustment assembly can refer to the structure of the first lateral adjustment assembly in the above embodiments, and the detailed description of the present application is omitted.

In this embodiment, the second lateral limiting member 300 and the first lateral limiting member 200 are both movable, so that the width of the feeding channel can be rapidly adjusted, and the two are symmetrically adjusted, so that the bar 1 can be always conveyed along the center line of the conveying surface a. Namely, when the bar stocks 1 with different lengths are conveyed by the feeding device, other equipment can conveniently receive the bar stock 1 workpieces with different lengths and sizes at the same position. For example, the manipulator is used for grabbing the bar stock 1, in this embodiment, different batches of bar stocks 1 with different lengths are always conveyed along the center line of the conveying surface a, and the manipulator with a set position can grab the middle parts of the bar stocks 1 with different lengths at the same position, so that the grabbing efficiency is improved.
