Abstract

An industrial truck includes a pair of forks mounted on a carrier at one end of a boom. The boom can be traversed in a constrained manner, one end of the boom following a D-shaped path, the boom having components of movement lengthways, fore and aft of the truck and laterally, across the truck and the carrier can be swivelled relative to the boom. Mechanical or electrical constraints may be incorporated to permit pivoting of the carrier about an axis spaced from the end of the boom so that the forks may be rotated within the width of the truck before any sideways reach movement.

Description

PATENT SPECIFICATION
( 21) Application No 5463/77 ( 22) Filed 10 Feb 1977 ( 23) Complete Specification filed 3 Feb 1978 ( 44) Complete Specification published 1 July 1981 ( 51) INT CL 3 B 66 F 9/14 ( 52) Index at acceptance B 8 H 509 600 603 PD ( 72) Inventor CECIL GOODACRE ( 11) 1592057 ( 54) INDUSTRIAL TRUCK ( 71) We, LANSING BAGNALL LIMITED, a British Company, of Kingsclere Road, Basingstoke, Hampshire, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the follow-
ing statement:-
The invention relates to industrial loadcarrying trucks It is known to provide, in an industrial truck, a load carrier, such as a pair of lifting tines, which is mounted for up and down movement and is rotatable about an upright axis as well as bodily movable from side to side of the truck in order that loading and unloading can be effected in a direction laterally of the truck Hitherto the range of up and down movement of the load carrier has been restricted owing to the need to provide pivots which are aligned with the axis about which the load carrier is rotated.
The presence of a lower pivot inhibits the movement of the load carriage down to ground level and the presence of an upper pivot inhibits the movement of the load carriage to the greatest height which might otherwise be possible The present invention is intended to provide, at least in some embodiments, an industrial truck in which some of this restriction of movement is removed and has a general object of providing an improved industrial truck.
The invention provides an industrial truck in which a load carrier, such as a pair of lifting tines, is mounted on a support which is pivotally mounted about an upright axis at one end of a boom which is bodily movable along and across the truck, and the movement of the boom is constrained such that the end which supports the carrier is constrained to move along a horizontal D-shaped path, and in which there are means for imparting rotary movement to the carrier in accordance or in synchronism with movement of the said end around the arcuate part of the said path such that the movement of the end around the arcuate part of the path is automatically accompanied by swivelling of the load carrier about an axis parallel to and spaced from the said upright axis.
Preferably there is imparted to the carrier a swivelling movement which during movement of the said end from the centre to one or other end of the arcuate part of the path changes the carrier’s attitute from along a 55 bisector of the D, normally fore and aft of the truck, to facing the bisector, namely normally laterally inwardly of the truck-preferably the attitude of the carrier during movement of the said end along the straight part 60 of the path can be maintained invariant so that the carrier may be bodily moved across the truck to project from one or other side thereof according to its attitude.
The coupling or association of the swivell 65 ing of the load carrier and the movement of the beam may be mechanical For example, in one embodiment of the invention the boom is constrained to maintain the same attitude towards the truck, preferably by 70 means of two D-shaped tracks which are followed by two parts of the boom and the boom carries a swivelling slider engaging a slot in an arm which is disposed to swivel about a point on the common centre line of 75 the D-shaped tracks As the various parts of the boom move around arcuate paths, the slider swivels relative to the boom; the slider may be connected by means of an endless chain or like transmission to the load carrier 80 so as to convert the arcuate movement of the boom into a corresponding rotation of the load carrier When however the boom moves laterally across the truck, corresponding to movement along the straight parts of the D 85 shaped path or tracks, the slider does not rotate relative to the boom and the attitude of the carrier remains unchanged The coupling or association of the movements of the boom and the carrier may be partly electrical For 90 example, in another embodiment of the invention the boom can be moved across and along the truck by means of respective electrical motors and the swivelling movement of the carrier relative to the boom is 95 also controlled by an electric motor In this embodiment of the invention the driving signals to the motors may be governed by a control system which effectively constrains the movements of the boom and the carrier 100 0 _ ( 19) 1,592,057 in the same way as does the mechanical transmission described in the foregoing but it is not necessary to provide any physical Dshaped track for constraining the movement of any part of the boom It is also possible to provide a system which is partly mechanical and partly electrical so as to provide by appropriate mechanical restraint and electrical synchronisation the same constraint that the wholly mechanical or wholly electrical system provides.
Reference will hereinafter be made to the accompanying drawings, of which:Figures 1 to S are explanatory diagrams which illustrate schematically various phases in the movement of a load carrier in accordance with the present invention; Figure 6 is a simplified, perspective view of the principal parts of one embodiment of the invention; Figure 7 is a simplified perspective view of an industrial truck incorporating one embodiment of the invention; Figure 8 illustrates another embodiment of the invention; and Figure 9 is a schematic diagram of an electrical control system which may be used to control the latter embodiment of the invention.
In each of Figures 1 to 5 of the drawings, there is shown, on the left-hand side, part of the lifting mechanism of a fork-lift truck which may be supposed to be only slightly less wide than an aisle between two parallel walls 1 and 2, each of which is constituted by storage racks It is customary to load goods into, and unload goods from, the storage racks by the insertion of a load carrier into the racks in a direction laterally of the truck.
Carried for and aft of the truck, the rest of which is omitted in these Figures, is a boom 3 which at one end, normally its forward end, carries, about a vertical axis 4, a frame 5 which constitutes a support for two parallel lifting tines 6 and 7 which may support a pallet, package or other load 8 At the rear end of the boom is a gear-wheel 9, rotatable about a vertical axis, which engages a Dshaped geared track 10 of which the straight part is disposed transversely of the truck.
Near the middle of the boom is a similar gear-wheel 11 which engages likewise a respective D-shaped track l Oa The two gearwheels are linked together by a chain transmission 12 in order that they may be rotated conjointly A motor, which is not shown in Figures 1 to 5, drives the gear-wheels 9 and 11 Preferably the wheels are driven in synchronism so that as the gear-wheels 9 and 11 proceed around their respective tracks, the attitude of the boom relative to the truck remains unchanged and all parts of the boom describe a respective D-shaped path.
The illustration of the boom and the load carrier is repeated on the right-hand side of each of Figures 1 to 5 in order to illustrate schematically part of the transmission for the conversion of the movement of the boom into rotation of the lifting tines Near the middle of the boom 3 is a slider 14 which is 70 pivotally mounted in the boom and slidably mounted in the slot of a slotted arm 15 which is slidably mounted on a slider 16 which can swivel about an axis lying on the bisector 13 of the tracks 10 and l Oa The two sliders 14 75 and 16 enter the slot on different sides, so that, as will be seen, either may engage each end of the slot The slider 14 is mounted for rotation with a wheel which is linked by a chain 17 to another wheel, not shown, 80 mounted on the axis 4 and coupled to rotate the support 5 Accordingly, if the arm 15 and the boom 3 rotate relative to one another, the load carrier is rotated likewise.
Figure 2 illustrates one phase of the 85 movement of the assembly from the position shown in Figure 1 to a position, shown in Figure 3, in which the attitude of the load carrier has been changed from facing forwardly of the truck to facing laterally of the 90 truck During this movement the pivot 4 moves from the centre of the curved part of a notional D-shaped path to the extreme end of that curved part, just as the wheels 9 and 11 reach corresponding parts of the tracks 10 95 and 10 a During the movement the load carrier pivots about an upright axis which is spaced from the axis 4 and lies on the centre line 13 of the D-shaped tracks, and in this embodiment, the centre line of the truck 100 Figure 3 illustrates the phase at which the boom has reached the left-hand side of the truck, the load carrier facing inwardly so that in this position the load carrier is accommodated within the width of the truck 105 Figure 4 illustrates the phase of the movement of the boom transversely of the truck.
The wheels 9 and 11 now proceed along the straight parts of the D-shaped tracks 10 and l Oa, and the forward end of the boom 3 110 proceeds along the straight part of the notional D-shaped path that it follows For this phase of the movement of the boom there is no relative rotation between the boom and the arm 15, and accordingly the 115 attitude of the load carrier remains the same during the sideways movement of the boom.
This sideways movement continues until the boom reaches the other side of the truck; then the load carrier faces outwardly and the 120 tines project into the space 18.
If the wheels 9 and 11 are connected by a coupling which includes, for example, a clutch, so that the wheel 9 is disposed slightly inwardly of the lateral limit of the track 10 125 when the wheel 11 reaches the lateral limit of the track 1 Oa, the forward end of the boom may be given an additional sideways movement.
Figure 6 illustrates a physical embodiment 130 1,592,057 of the mechanism of which the operation has been described with reference to the preceding Figures The mechanism is carried by a C-shaped frame 20, of which the lower arm 21 carries the geared tracks 10 and l Oa The upper arm 22 of the frame 20 carries a track lob, which is disposed vertically above the track 10 and is engaged by a gear-wheel 23 which is disposed on a common shaft 24 with the gear-wheel 9 This arrangement provides the boom with vertical stability In this embodiment, the transmission 12 comprises two sprocket wheels 25 and 26 disposed for conjoint rotation with the shaft 24 and the wheel 11 respectively and two similar wheels 27 and 28 mounted on the output shaft 29 of an electric motor 30 The slider 16 which slides in the upper side of the slot of the slotted arm 15 is pivotally mounted in the foward extremity of the upper arms 22 of the frame 20.
The embodiment shown in Figure 6 is, apart from the motor 30 which merely provides motive power, a wholly mechanical linkage for moving the boom and connecting the arcuate movement of the boom to the carrier 5 The arrangement is particularly convenient, but not essential Either or both the tracks 10 and l Oa may be omitted provided that their function is supplied by other means which can control and associate the movements of the boom and the load carrier in a manner similar to that which has been described.
Figure 7 illustrates the incorporation of the mechanism illustrated in Figure 6 in an industrial fork-lift truck The truck 31 has between its front wheels 32 an extensible mast 33 comprising a lower fixed section 34 consisting of two facing channels 35 and 36.
An upper, relatively movable part 37 of the mast runs in the channels and may be elevated by means of a hydraulic jack 38.
The frame 20 in this embodiment comprises, for the base of the C, two spaced apart bars in place of the single bar in Figure 6, and the tracks 10 and l Oa are moved close together, being slightly offset both in a fore and aft direction and at slightly different levels, to reduce the forward ovehang of the carrier 5 otherwise the arrangement of parts and the manner of operation are as described with reference to the preceding Figures.
Figure 8 illustrates the mechanical parts of a mechanism in which the coupling of the movements of the boom and the carrier is electrical.
In this embodiment the main frame 40 has an upper arm 41 and a lower arm 42 These arms support, respectively, an upper transverse geared channel 43 and similar, lower geared channel 44 The latter channel has two geared tracks 45 and 46 facing each other on opposite sides of the channel; the upper channel is similarly constituted The boom 47 in this embodiment has a box section It has a longitudinal slot 48 in its upper side surface and a similar slot 49 in its lower surface At the front of the boom, the support for the forks 51 and 52 is mounted by 70 means of a swivel 53 A motor 54, which is mounted at the front end of the boom, rotates the support 50 in azimuth about the end of the boom.
Two geared tracks 56 and 57 extend along 75 and inside the broad side walls of the boom 47 The boom contains a carriage 58, which contains two motors 59 and 60 These motors provide respectively lateral movement of the boom and fore and aft movement of the 80 boom The two motors are fixed within the carriage 58 The motor 59 has an output shaft 61 which extends in opposite directions out of the carriage 58 through the slots 48 and 49.
The two ends of the shaft 61 terminate in 85 gear-wheels 62 and 63 respectively The gearwheel 63 engages the track 45 in the channel 44, whereas the gear-wheel 62 engages the corresponding track in the channel 43 Also mounted in the carriage 58 is a shaft 64, 90 which extends out of the carriage and through the slots 48 and 49 to terminate in respective gear-wheels 65 and 66, which are in mesh with the gear-wheels 62 and 63 respectively and also in mesh, respectively, 95 with the respective track of the channel 43 and 44 The rotation of the motor 59 accordingly drives the boom 47 sideways.
The motor 60 has an output shaft carrying a gear-wheel 67, which meshes with a gear 100 wheel 68 that is in mesh with the track 57 and also in mesh with a gear-wheel 69 which is in mesh with the track 56 Rotation of the shaft of the motor 60 drives the tracks 56 and 57 and accordingly the boom which is attached 105 to them in a fore and aft direction The carriage 58 carries rollers 70 and 71, and other rollers not shown, which bear against the side walls of the boom and permit the boom to move longitudinally with respect to 110 the carriage 58.
It will be observed that the degrees of freedom that the assembly shown in this Figure provide enable the load carried constituted by the forks to be moved in a manner 115 as described with reference to Figures 1 to 5 if that be desired; the task of providing sufficient electrical interlocks and electrical synchronisation is comparatively simple and may readily be fulfilled with the aid of 120 known techniques For the sake of completeness, a suitable control system will be briefly described, but its particular arrangement is not important.
Power for the three motors is supplied by a 125 pair of lines 80 and 81 connected directly or indirectly to the battery of the truck The positive line 80 includes a circuit breaker 82.
For each of the motors 59, 60 and 54 there is a set of selection switches, 83, 84 and 85 130 1,592,057 respectively for determining the sense of rotation of the respective motor The motors are driven by the supply of electrical pulses; the respective motor pulse control circuits 86, 87 and 88 may each include a current chopper for that purpose These latter circuits are under the control of control units 89, and 91 respectively; these units determine the direction, rate and duration of the movements of the motors in accordance with control signals from a sequence and position control unit 92, which may be constituted by any suitably programmed microprocessor.
This unit 92 receives signals from three sets of limit switches 93, 94 and 95, which signal when the boom reaches any of its limits of its sideways or longitudinal movement and when the load carrier reaches or approaches either of its limits of rotary movement relative to the boom These limit switches may be positioned as desired The unit 92 also receives signals from sensors 96, 97 and 98, which monitor the actual transverse and longitudinal positions of the boom and the angular position of the load carrier relative to the boom A safety control unit 99 monitors the signals produced by the sensors 96 to 98 in order that, if for example the signals denote excessive movement of the boom or load carrier, the circuit breaker 82 may be operated to terminate the supply of power to the traversing mechanism Movements of the mechanism may be initiated by means of an operator’s control 100 which is associated with a customary set of interlocks 101.
The programming of the microprocessor to produce for the embodiment of the last two Figures the movements illustrated in Figures 1 to 5 is quite straightforward and in the present state of the art requires no additional instruction Owing to the substantial inertia of the system and the inevitable time lags in its movements in response to control signals, it may be difficult to ensure that, for example, during rotation of the load carrier the longitudinal and transverse movements of the boom are related such as to be closely proportional to the sine and cosine of the angle of the carrier relative to the boom, but provided the boom is moved relatively inboard as the carrier rotates there is normally sufficient margin for error.
