Description

[Detailed description of the invention] The present invention is a conveyor that allows the installation posture to be varied in various ways, increases the degree of freedom in selecting the installation position, and allows necessary equipment and auxiliary tools to be easily installed in any position. Related to wheel guide rails.

Conventionally, the guide rails for rolling wheels attached to the top and bottom of a conveyor are integrally formed at the top and bottom of one guide rail member, respectively, so the vertical distance between the top guide rail and the bottom guide rail is fixed. Not only that, but the degree of freedom in the mounting position of the guide rail member is completely lost, and when mounting the guide rail member on the rail support frame, mounting bolt insertion holes must be drilled in the guide rail member or welded. etc., and when fixing with mounting bolts, the heads of the bolts or nuts protrude into the inner surface of the guide rail member, hindering the operation of the conveyor, and when welding, the guide rail members may be subject to thermal distortion. This not only causes deformation of the rail guide surface, impeding the smooth operation of the conveyor and causing noise, but also has the disadvantage that guide rail members cannot be easily replaced due to wear and tear. had.

The present invention is a guide rail for conveyor wheels that eliminates the above-mentioned conventional drawbacks and allows necessary equipment to be easily attached and detached to any position on the guide rail. To explain an example, as shown in FIG. 1, the conveyor wheel guide rail of the present invention is provided on a substantially L-shaped rail member 3 having a vertical side 1 and a horizontal side 2 that are orthogonal in cross-section. A wide locking groove 4 for rail attachment is formed in the longitudinal center of the outer surface of side 1, and narrow locking grooves 5 and 5' for device attachment are formed on both upper and lower sides of the groove 4, respectively. A wide locking groove 6 for installing a rail is formed near the vertical side 1 in the longitudinal direction of the lower surface of 2, and a narrow locking groove 7 for installing equipment is formed near the free end. An upright conveyor wheel circumferential guide rail 8 and a downward-facing device mounting locking groove 9 facing the horizontal side 2 are formed extending at the end, and an upright conveyor wheel circumferential guide rail 8 is formed at the free end of the horizontal side 2 facing the vertical side 1. A conveyor wheel inscribed guide rail 10 is formed. Then, on the top surface of the conveyor wheel inscribed guide rail 10 that stands upright on the horizontal side, a ring 11 to be fitted is made of a material different from that of the conveyor wheel, for example, when the conveyor wheel is made of metal, the ring 11 is made of resin.
It is also possible to attach the top surface to the conveyor horizontal shaft wheel rolling rail 12.

Therefore, to explain the case where the conveyor wheels are an upper vertical shaft wheel 14 and a lower vertical shaft wheel 15 attached to the back of a horizontally moving article storage shelf 13 as shown in FIG. 2, both wheels 14 and 15 are vertical shaft wheels. Since the wheel guide surfaces of the conveyor wheel guide rails 8 and 10 must be installed in an upright position, the rail support frame 16
is upright, insert the locking plate 18 into which the bolt 17 is inserted into the rail mounting locking groove 4 of the wide outer surface of the vertical side 1, and insert the bolt into the rail support frame 1.
6 is inserted into the bolt insertion hole 19 and fastened with a nut 20 to removably fix the vertical side 1 of the L-shaped rail member 3 to the rail support frame 16, and when the rail support frame 16 is lying horizontally. If so, insert a locking plate into the locking groove 6 for rail attachment on the lower surface of the horizontal side, and attach the horizontal side 2 of the L-shaped rail member 3 to the top surface of the rail support frame in the same manner as described above. Fix it. Further, when the horizontal side 2 is to be fixed to the lower surface of the rail support frame in a lying state, the L-shaped rail member 3 can be attached by turning it 90 degrees so that the lower surface of the horizontal side 2 becomes the upper surface. Furthermore, when connecting multiple conveyor rails in the longitudinal direction, if there is a slight deviation in the vertical and horizontal directions between the connecting end surfaces of both rails, the rolling guide surface of the wheels may become discontinuous at the connecting point when the conveyor wheels roll. Although this may cause derailment or cause the conveyor to sway and generate impact noise, hindering the smooth operation of the conveyor, it is necessary to insert and erect a connecting plate spanning both rails into the rail attachment locking groove 4 or 6 at the connection point of both rails. By doing so, the connection end faces of both rails can easily match with each other using the connecting plate as a gauge plate, and the work of connecting the ends of both rails without a step can be carried out extremely easily and quickly. Moreover, since the longitudinal mounting position of the rail member 3 can be freely adjusted by loosening the tightening of the mounting bolt 17, the longitudinal dimension position of the bolt insertion hole 19 bored in the rail support frame 16 can be specified. Even without it, the rail member 3 can be easily fixed.

In addition, narrow locking grooves 5, 5', 7 for installing devices are also available.
and 9 are installed along the length of the rail, so there is no need to separately install support members for the various detection devices necessary for conveyor operation control, and they can be freely selected at any position on the rail member. In particular, a large number of devices necessary for computer control of the conveyor can be directly attached and fixed to the rail member, and the longitudinal mounting position of these devices can also be freely adjusted.

As described above, the conveyor rail of the present invention not only has a high degree of freedom in the mounting position with respect to the rail support member, but also is extremely easy to adjust the mounting position in the longitudinal direction, and can be attached to and removed from the rail support frame. In addition, the various detection devices necessary for conveyor operation control can be directly fixed at any position in the longitudinal direction of the rail member in an adjustable manner. Since it is integrally equipped with an inscribed guide rail, when horizontally moving the shelves 13, 13' arranged vertically in multiple stages as shown in FIG. By mounting the upper and lower vertical wheels 14 and 15 simultaneously, it becomes possible to guide the upper and lower vertical wheels 14 and 15 at the same time. This can be easily done by changing the spacing depending on the shelf height and attaching it to the rail support frame 16, so there is no need to replace the rail every time the shelf height is changed, unlike the conventional rails mentioned above.

When the shelf 13 is guided in a cantilevered manner as shown in FIG. 2, the lower vertical shaft wheels 1
5 may float from the circumscribed guide rail 8, it is also possible to attach a floating prevention guide plate 21 to the downward-facing device mounting locking groove 9. Moreover, even if the rail is attached to the rail support frame and various detection devices and other auxiliary tools are attached to the rail, there are no mounting bolt heads or parts on the inner surface of the rail.
Since no protruding parts such as nuts are formed, there is no hindrance to the rolling guidance of the conveyor wheels, and smooth operation of the conveyor can be expected.
