  An example of the present invention will be described.

  Hereinafter, an embodiment of the present invention will be described. 1 is a conveyor (conveying means such as a belt conveyor or a roller conveyor), and the conveyor 1 includes a pair of conveyor side plates 100 (side plates) constituting a frame, A plurality of drive rolls 101 (rotary rolls, rolls) fixed between the conveyor side plates 100, a belt 102 suspended between the drive rolls 101, a drive source (not shown), a plurality of bearings, and the like are the main components. Accordingly, the conveyor belt 1 is movable in the direction of the arrow “A” on the drawing through the rotation of the drive source.

  2 is an auxiliary roller conveyor for transit, and the main structure of the auxiliary roller conveyor 2 for transit is the substantially L-shaped side plate 200 and the side plate 200 as viewed from the side attached to the frame (conveyor side plate 100) of the conveyor. A drive transmission pulley 3 that comes in contact with the belt 102 of the conveyer 1 or a belt 102 (described by the belt 102) suspended on the drive roll 101, and a contact between the drive transmission pulley 3 and the side plate 200. The transfer roller conveyor 5 is provided with a difference, and the rotation of the transfer roller conveyor 5 of the auxiliary transfer roller conveyor 2 (direction of arrow “C”) and the rotation of the belt 102 of the transfer conveyor 1 (arrow) Rotate in the same direction and / or speed (the same speed is ideal considering the efficiency of transport, stability, etc.) ). The side plate 200 movably attaches to the conveyor side plate 100 to support the lower-stage side plate portion 200-1 having the long holes 200a and the drive transmission pulley 3 shorter than the lower-stage side plate portion 200-1. An intermediate side plate portion 200-2 for contacting the belt 102, a bracket 200b provided at an attachment end portion of the intermediate side plate portion 200-2, an upper stage side plate portion 200-3 that does not bump against the conveyor side plate 100, and a light weight In consideration of reduction, material saving, safety, etc., a notch 200-4 provided on the free end side of the lower plate part 200-1 (this notch 200-4 is provided if necessary) Consists of. Since the side plate 200 has a pair structure, one side has been described (note that the pair structure has the same description).

  Next, the structure of the drive transmission pulley 3 will be described. The drive transmission pulley 3 is a shaft portion that is fitted in the elongated hole 200-5 in the left-right direction (arrow A direction) of the intermediate side plate portion 200-2 of the side plate 200. 300, a rotary roll 301 provided in the shaft portion 300, and a spring 302 suspended between the shaft portion 300 and a mounting tool 305 attached to the bracket 200b. This structure is driven by contact with the belt 102 of the conveyor 1 (not shown, but a roll or the like is also possible). The rotation of the drive transmission pulley 3 is opposite to the rotation of the belt 102 (in the arrow “A” direction) as shown in the figure (the arrow “B” in the clockwise direction). And this fixture 305 moves to the left-right direction (arrow A direction) in FIG. 3 from the vertical direction of the bracket 200b as a base point. For example, by moving to the left direction, the spring 302 is relaxed and the contact with the belt 102 is loosened, and conversely, by moving to the right direction, the spring 302 is tensioned and the contact with the belt 102 is made. Increase the pressure (adjustment of contact pressure). This operation uses a pair of nuts 303 provided on the screw shaft of the fixture 305. Note that, when the spring 302 is relaxed and / or tensioned, the shaft portion 300 moves in the long hole 200-5 (in FIG. 3, the left-right direction (the direction of arrow A)). Further, the long hole 200-5 is used to reduce the impact on the drive transmission pulley 3.

  The structure of the connecting roller conveyor 5 will be described. The connecting roller conveyor 5 is fitted into a long hole 200-6 in the vertical direction (in the direction of arrow B) of the upper side plate portion 200-3 of the side plate 200. A shaft portion 500, a rotating roll 501 provided in the shaft portion 500, and a pin 502 for preventing the slippage provided in the shaft portion 500. The connecting roller conveyer 5 has its own weight. In this structure, the drive transmission pulley 3 is brought into contact with and / or driven through forcible means by another mechanism. By adopting this structure, the connecting roller conveyor 5 rotates in the same direction as the rotation of the belt 102 of the transport conveyor 1 (in the direction of the arrow “I”) (the arrow “C” in the counterclockwise direction). direction). Further, the connecting roller conveyor 5 comes into contact with the drive transmission pulley 3 through its own weight and / or forced means by another mechanism, and appropriately moves up and down (arrow B) in the long hole 200-6. Direction), the belt 102 of the conveyor 1 rotates at substantially the same speed as the rotation speed. There is a feature that parts can be conveyed without stagnation and damage through the rotation at substantially the same speed. Further, the long holes 200-6 are used to reduce the impact on the transfer roller conveyor 5.

  In the figure, reference numeral 7 denotes a ring, and the ring 7 is fitted to the drive transmission pulley 3 as a pair. By providing the rings 7 in pairs, the rotation of the drive transmission pulley 3 is reliably and smoothly transmitted to the connecting roller conveyor 5. The characteristics of the ring 7 are that the drive transmission pulley 3 and / or the connecting roller conveyor 5 is driven as long as the ring 7 does not change even if an abnormal situation occurs such as bending or deformation. The rotation of the transmission pulley 3 is transmitted to the connecting roller conveyor 5. Further, in order to securely and easily fix the ring 7 at a predetermined position of the drive transmission pulley 3, a projection and a groove are provided in the ring 7 and / or the drive transmission pulley 3 (not shown). It is desirable to adopt a structure provided intermittently or a structure provided with protrusions as appropriate.

  Even if there is a gap between the belt 102 of the transfer conveyor 1 and the transfer roller conveyor 5 of the auxiliary transfer roller conveyor 2 by the auxiliary transfer roller conveyor 2 of the present invention described above, The rotational force of the splicing roller conveyor 5 urges conveyance of the object to be conveyed (article) in the flow direction (arrow “d” direction).

  In the present invention, even if there is a gap between the conveyor 1 and the conveyor 1, the transfer roller conveyor 5 can be used for conveyance. Therefore, the object to be conveyed preferably has a flat bottom surface. Good. The reason for this is that if there are protrusions or protrusions on the lower surface of the object to be conveyed, there is a possibility of being caught in the gap between the conveyor 1 and the transfer roller conveyor 5.

  The drive transmission pulley 3 and / or the transfer roller conveyor 5 are preferably a free roll mechanism.
