Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a conveyor suitable for conveying a relatively light, bulky and unspecified shape.
[0002]
[Prior art]
For example, scraps produced by punching corrugated board when manufacturing cardboard boxes, etc., have been transported and discharged by transport equipment such as belt conveyors in the factory. However, conventional belt conveyors generate large scraps. In order to be able to be received, it is necessary to design wide, so there is a problem that the manufacturing cost becomes high.
[0003]
In addition, if the width of the conventional belt conveyor is not sufficient, when transporting a light and bulky object such as the above scrap, if the object is shifted laterally and hits a side plate or the like, the conveyed object becomes a belt surface. It sometimes floated and could not be transported skillfully.
Further, since the belt conveyor is generally thick as a device, it may not be installed in a lower space of a corrugated cardboard punching machine, for example. Further, in the belt conveyor, there is a possibility that small corrugated cardboard waste or the like is caught between the rollers.

Embodiments of the present invention will be described below with reference to the drawings. 1 is a perspective view of a conveyor according to the present invention, FIG. 2 is a transverse sectional view thereof, and FIG. 3 is a sectional view taken along line AA of FIG. In the figure, 1 is a long fixed table with a flat top surface and a side plate 2 provided on one side edge, and 3 is a comparison of corrugated cardboard waste discharged from a corrugated cardboard punching machine etc. Lightweight and unspecified shape.
[0007]
A screw shaft 6 is rotatably supported along a longitudinal direction of the fixed table 1 on a machine frame 5 provided on the other side edge of the fixed table 1, and the screw shaft is driven by a driving motor (not shown). The screw shaft is provided with a ball screw 7, a fulcrum shaft 8 is suspended from the ball screw, and the screw shaft is rotated forward and backward so that the fulcrum shaft is connected to one side of the fixed table 1. Are configured to reciprocate. Reference numeral 10 denotes a plate-like pushing arm that is supported on the fulcrum shaft 8 upright by bearings 11 and 12 and is supported so as to be rotatable in a horizontal plane. Further, bearing pieces 14 and 15 are provided on the base portion 13 of the push arm, and a pair of rollers 16 and 17 are rotatably supported on the bearing piece, and a plane J-shaped bent piece 18 is extended to the upper side portion of the base portion 13. Has been established. Reference numeral 20 denotes a brush that is fixed to the lower side of the feeding arm 10 by a stopper piece 21 so that the tip is in contact with the upper surface of the fixed table 1.
[0008]
Reference numeral 25 denotes an attitude control rail provided on one side of the fixed table 1 for controlling the attitude of the push-arm 10, and reference numerals 26 and 27 denote rear surfaces of the rails for supporting the attitude control rail so as to be movable forward and backward. A guide mechanism 30 comprising a rack 28 and a pinion 29 provided on the cylinder 30 is a cylinder for moving the attitude control rail forward and backward so that the rail can come into sliding contact with the rollers 16 and 17. Further, 31 is a front end fixing attacker fixed to the machine frame 5 in a suspended manner, 32 is a rear end fixing attacker fixed to the machine frame 5 in a suspended manner, and the front end fixing attacker 31 is formed of the bent piece 18. The rear end fixing attacker 32 can face the back surface of the bent piece 18.
[0009]
Therefore, as shown in FIG. 3, when the pusher arm 10 is now advanced in the direction indicated by the arrow by rotationally driving the screw shaft 6, the rollers 16, 17 slide on the attitude control rail 25. The pushing arm 10 comes into contact with the feed table 10 in an overhanging shape on the fixed table 1 and perpendicular to the carrying direction, and can feed the conveyed product 3 such as cardboard scraps on the fixed table 1 in the direction of the arrow. When the push arm 10 comes to the extreme end, as shown in FIG. 4, the front end fixing attacker 31 collides with the front surface of the bent piece 18, and the cylinder 30 is operated to slightly advance the posture control rail 25. As a result, the rollers 16 and 17 are pushed, so that the feed arm 10 turns forward with the fulcrum shaft 8 as a fulcrum, and the conveyed product 3 can be discharged from the fixed table 1. Further, by further moving the posture control rail 25 forward, the push arm 10 becomes parallel to the conveying direction as shown in FIG. 5, and the contracted posture is maintained by rotating the screw shaft 6 in the reverse direction. The pushing arm 10 can be retracted. When the push arm 10 comes to the rear end, the cylinder 30 is operated to move the posture control rail 25 backward, and the rear end fixing attacker 32 collides with the back of the bent piece 18 as shown in FIG. The pushing arm 10 is returned to an overhanging shape as indicated by an arrow, and the overhanging shape is maintained by the rollers 16 and 17 being brought into sliding contact with the attitude control rail 25, and the screw shaft 6 is rotated in the forward direction again. By driving, the conveyed items such as cardboard scraps newly discharged onto the fixed table 1 can be pushed one after another as shown in FIG. Since the brush 20 is provided so as to be in contact with the upper surface of the fixed table 1, the brush 20 is wiped out without leaving any fine waste.
[0010]
In this embodiment, the screw shaft 6 and the ball screw 7 are shown as means for reciprocating the fulcrum shaft 8, but they may be reciprocated by chain drive or cylinder drive. Also, the means for moving the attitude control rail 25 forward and backward does not stick to the driving by the cylinder 30 shown in the embodiment. In this embodiment, the front end fixed attacker 31 is provided. However, the forward end fixed attacker 31 is not necessarily provided because the push-arm 10 can be turned by advancing the attitude control rail 25 at the front end. . Further, the J-shaped bent piece 18 provided at the base of the pusher arm 10 smoothly turns to return the pusher arm 10 to the protruding state when it collides with the rear end fixed attacker 32.
[0011]
Moreover, although the case where a conveyed product was conveyed horizontally was demonstrated in this embodiment, this conveyor can also be used when carrying a conveyed product on the pushing arm 10 and conveying in a slanting shape or vertically.
[0012]
