Abstract
A spring fixing arrangement for the cantilever springs or leaf springs 4, of a linear vibratory conveyor to provide a means of gripping the ends of the springs 4 with less stress in the bolts 2 than occurs for the bolts used in the conventional method, comprises a spring fixing body 1 welded or bolted to the base or trough carriage. The bolt or bolts 2 are used to clamp a pressure segment 3 against the springs 4 and may also be used to secure the spring fixing body 1 to the base or trough carriage. A shock absorber 5 may be provided between the pressure segment 3 and spring 4, and a dowel 7 may be used for location purposes or to prevent slip. <IMAGE>
Description
VIBRATORY CONVEYOR SPRING FIXINGS
This invention relates to an improved spring fixing arrangement for the cantilever springs or leaf springs of a linear vibratory conveyor.
Referring to Figure 1, a typical conventional linear vibratory conveyor has a conveyor trough and its carriage 1 connected to the base 2, by leaf springs or cantilever springs 3. These are usually inclined to the vertical to provide the required conveyor motion.
Also shown is the electric magnetic drive 4, air gap 6 and shock absorbers 5.
Figure 2 illustrates the conventional method for connecting the springs to the base and to the trough carrier. On large units two lines of staggered bolts may be required and this usually involves a very large number of nuts and bolts for the conveyor as a whole and these are usually deployed in a position inaccessible to any automatic nut tightening device. The choice of spacers and the degree oif tightening down may be used to help tune the vibrator to the required resonant frequency or near resonant frequency.
To change the springs can be very laborious.
Two specific embodiments of the invention are shown in Figure 3 and these provide a means of gripping the spring ends with less stress in the bolts and allowing fewer bolts to be used.
They facilitate an easy method for changing the springs and with no bolt holes required in the springs there is less spring area requiring to be gripped.
The upper spring fixing illustrated in Figure 3 may be directly welded to the trough carriage on to the base whichever applies.
The lower spring fixing illustrated in Figure 3 uses a channel
Section 1 which can be bolted or welded in the desired position on the trough carriage or onto the base whichever applies, and this spring fixing can be manufactured as a ready-made unit. It it bolted on to the trough carriage or on to the base by the same bolts 2, that hold the springs 4 in position.
Figure 4 shows another embodiment of the invention which uses a corner insert 6, which is placed within the channel section 1, the channel section being mahcined to accommodate the corner insert.
Referring to Figure 3 and Figure 4 the identification of the components is as follows
1. the channel section or main body
2. the fixed bolt which may be one of several in line behind
3. the insert pressure segment which presses against the spring
4. the spring
5. the spacers
6. the corner insert piece
7. the location dowels
Claims (4)
- CLAIMS 1. This cantilever spring fixing for the linear vibratory conveyor provides a means of gripping the spring ends with much less stress in the bolts than in the conventional method and permits fewer bolts to be used.2. This cantilever spring fixing for the linear vibratory conveyor requires no bolt holes in the springs and less spring surface area is required to be gripped.3. This cantilever spring fixing for the linear vibratory conveyor provides a very easy method for changing the springs.Amendments to the claims have been filed as follows 1. This cantiliver spring fixing concerns a leaf spring end mounted by means of a clamp or wedge at the angle of inclination required by the linear vibrator concerned.
- 2. This cantilever spring fixing for the linear vibratory conveyor provides a means of gripping the spring ends with much less stress in the bolts than in the conventional method and permits fewer bolts to be used.
- 3. This cantilever spring fixing for the linear vibratory conveyor requires no bolt holes in the springs and less spring surface area is required to be gripped.
- 4. This cantilever spring fixing for the linear vibratory conveyor provides a very easy method for changing the springs.
