Description

[Detailed description of the invention] Technical field The present invention is a method for changing the conveyance path of a conveyed object on a horizontal belt conveyor to carry out the conveyed object or transfer it to another horizontal belt conveyor. Regarding equipment.

Prior Art This type of conveyance path switching device has been known for a long time, but in the conventional example, a boss is provided on the shaft and the boss is moved by a solenoid or a motor to move the object to be conveyed. The transportation route was being changed. For this reason, each component is exposed and easily damaged, and it has the disadvantage that it occupies a large area.

Purpose The present invention aims to eliminate the above-mentioned drawbacks, protect each component, and provide a conveyance path diversion device for a horizontal belt conveyor that is downsized.

Overview In order to achieve the above-mentioned object, the present invention supports a shifter on a fixed member provided along the conveyance path of a horizontal belt conveyor so that it can swing parallel to the belt surface at an intermediate portion in the longitudinal direction. A hollow part is formed from the supporting part to the proximal end side and is open at least on the fixed member side, and a drive source such as a solenoid and a shifter actuated by the drive source are positioned in this hollow part. The shifter is provided with an actuating member that swings the shifter to change its conveyance path, and a resilient member such as a coil spring that returns the shifter to its original state.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view showing a conveyance route switching section of a horizontal belt conveyor, in which a pair of guide frames 2 and 3 are provided along a belt 1, and a guide frame 3
A notch 4 is formed in the conveyor for transporting an object (not shown) from the conveyance path. A fixing metal fitting 5 serving as a fixing member is located at one end of this notch 4 and is screwed to the guide frame 3. A hollow shifter 6, which is slightly shorter than the notch 4, is loosely fitted into the fixing fitting 5 with screws 7 and 8 at a slightly proximal end side of the center, and is swingable parallel to the belt 1 surface. Supported. This shifter 6 is
The width gradually increases from the distal end to the proximal end, and the side surface portion corresponding to the fixing metal fitting 5 and the proximal end surface portion are open, while the width from the supporting portion to the fixing metal fitting 5 to the proximal side is opened. The enlarged hollow part serves as an interior part 9. As is clearer from FIGS. 2 and 3, a solenoid 10 serving as a driving source is fixed to the fixing fitting 5 in the interior portion 9. Below the solenoid 10 is a pair of L-shaped support fittings 1 which are also located in the interior portion 9 and have a rotation shaft 11 screwed to the fixing fitting 5.
2 and 13 so as to be rotatable. An operating member 14 located in the interior portion 9 is fitted and fixed to the protruding end of the support fitting 13 of the rotating shaft 11 while tilting in the direction opposite to the fixing fitting 5, and the upper end surface of the operating member 14 is formed in a rounded shape. and is in contact with the inner wall surface of the shifter 6. Further, an engagement plate 15 is fixed to the rotation shaft 11, and this engagement plate 15 is connected to the solenoid 1.
0 drive shaft 16. The lower surface of the proximal end of the shifter 6 and the lower surface of the fixed end of the fixing fitting 5 include
Bolts 17 and 18 are fixed respectively, and each end of a coil spring 19, which is a resilient member, is engaged with these bolts 17 and 18. Due to the elastic force of this coil spring 19, the shifter 6 is moved to the first position.
While it is urged to swing counterclockwise in the diagram,
By coming into contact with the actuating member 14, it remains stationary in the standby position.

Next, the operation of this embodiment will be explained. When the shifter 6 is in the standby position shown by the solid line in FIG. 1, the object conveyed on the belt 1 is conveyed along the normal conveyance path. In order to transport the object from this transport path, the solenoid 10 may be driven in accordance with the transport state of the object. Then, the drive shaft 16 projects and pushes the engagement plate 15 downward, and the rotation shaft 11 is rotated clockwise in FIG. 3. Therefore, the actuating member 14 swings clockwise in the figure to push the shifter 6, and the shifter 6 swings clockwise in the figure 1 with each screw 7, 8 as a fulcrum, and its tip portion is in a switching operation state (the state shown by the imaginary line in FIG. 1) in which the robot enters the conveyance path. Therefore, the transported object is guided by the shifter 6,
It will be carried out from the conveyance path. Then, when the drive shaft 16 of the solenoid 10 enters, the engagement state with the engagement plate 15 is released, so the operating member 14
becomes free. This allows shifter 6
The actuating member 14 is returned to the position where the engagement plate 15 is locked to the drive shaft 16 by the elastic force of the coil spring 19, and is also returned to the standby position.

In the above embodiment, the swing range of the shifter 6 can be adjusted by adjusting the protrusion amount of the drive shaft 16 of the solenoid 10. Of course, the drive source in the present invention is not limited to the solenoid 10, and the shifter 6 does not need to be entirely hollow. In this way, the present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the technical idea thereof.

Effects As is clear from the above explanation, according to the present invention, the shifter can protect each component including the drive source, and can also be downsized, and furthermore, since each component is not exposed. It can have many effects, including superior appearance.
