Definitions

  • ABSTRACT Automatic machine for spraying shoe components Comprises a stationary spray gun and a rotary table carrying a support for a component to be sprayed. Support is moved linearly across the table and the table turned in pre-set sequence: so that the edge of the component is sprayed all round.
  • the invention finds 5 matic spraying machine, comprising a stationary sprayl ing device, a table which is turnable with respect to said device, a support for a component to be sprayed, the support being carried by the table for movement in a linear path across the same, and drive means for the table and for the support, whereby, in use, a compol nent to be sprayed can be moved past the spraying device linearly by movement of the support and in an arcuate path by turning the table.
  • a component to be sprayed is placed on the support and the machine operated to move the component in the required path. It will be appreciated that by effecting linear and arcuate movement of the component in appropriate sequence or simultaneously, the machine can be adapted to spray a wide range of different-shaped components. Moreover, the surface of the component being sprayed is maintained at a constant distance from the spraying device, which makes for uniformity of spraying.
  • second spraying device may be brought into operation; to spray the tread surface of the sole unit during one of the traverses of the support across the table. It will be appreciated that, by suitably modifying the sequence, platforms, foreparts etc., can also be sprayed.
  • the support is carried by a rod which projects upwardly through a diametral slot in the table and is connected, below the latter, to a piston and cylinder unit carried by the table and arranged to traverse the rod along the slot and so effect linear movement of the support.
  • the stroke of the piston and cylinder unit may be controlled by a cam which moves with said support and a switch which is operated by the cam, the position of the switch being adjustable to vary the stroke of the piston and cylinder unit and hence the extent of the linear movementof the support. In this way, the machine can be adjusted for spraying components of different lengths.
  • the speed of turning of the table may also be adjustable for the same reason.
  • FIG. 1 is a front view of a sole unit spraying machine in accordance with this embodiment
  • FIG. 2 is a plan view corresponding to FIG. 1,
  • FIG. 3 is a sectional view on line lll III of FIG. 2. looking from the rear of the machine,
  • FIG. 4 is a vertical sectional view on line IV IV of FIG. 3, and,
  • FIG. 5 is a diagram of the pneumatic circuit of the machine.
  • the machine basically comprises a floor-standing casing 1 presenting a flat upper surface on which is mounted a rotatable circular table 2 adapted to carry a sole unit to be sprayed (as will be described).
  • a frame 3 Mounted on the front side of the casing l is a frame 3 carrying a spray gun 4 of conventional form, the frame being adjustable both heightwise and laterally to vary the position of the spray gun 4.
  • Table 2 is formed with a diametral slot 5 through which projects a rod 6 connected by a screwthreaded coupling to a further co-axial rod 7 carrying at its upper end a support 8 for a sole unit (designated S).
  • the support comprises a pair of slotted slides 9 which are disposed with their side faces in sliding contact and are adapted to be locked in an adjusted position relative to one another by a pair of bolts 111) provided with wing nuts. This enables the length of the support to be adjusted to accommodate different-sized sole units.
  • Each slide 9 has a pair of upstanding pins 11 which engage and locate the face of the sole unit remote from its tread surface.
  • a drip tray 12 is provided at the bottom of rod 7 to collect excess paint falling from the sole unit S in use.
  • the slot is sealed by two spring steel strips 13 (see FIG. 3), received in guideways along the sides of slot 5.
  • Each strip is connected at one end to the rod 7 and at its opposite end is received in a housing 14 on the table, being arranged in a coiled configuration in the latter.
  • rod 7 moves along slot 5 as will be described, the strips 13 respectively coiling up into uncoiling from their housings 14 as the rod moves.
  • FIGS. 3 to 5 in describing the driving mechanism of the machine.
  • the mechanism is designed to initially move the sole unit support 8 from left to right (FIGS. 1 and 2) along the slot 5 in table 2, starting from the position shown, whereby one side edge of the sole unit S will be sprayed.
  • the mechanism rotates table 2 through halfa revolution in the anti-clockwise direction so that the spray gun applies paint to the heel edge of the unit; this brings the carrier 8 back to the starting position with the sole unit facing in the opposite direction.
  • the carrier is again moved from left to right along the slot in table 2 so that the other side edge of the unit is sprayed.
  • the table performs a further half a revolution in the anticlockwise direction so that the toe edge of the unit is vision is made in the machine for a second spray gun to be mounted on the lefthand end of the casing l to spray along the line of slot 5 and apply paint to the tread surface of the unit.
  • Two pairs of snap connectors a, 1512 are provided in the front of casing 1, each spray gun being plugged into one pair; only the pair 15a are being used in the illustrated embodiment.
  • FIG. 3 The part of the mechanism for moving the rod 6 (and hence the sole unit carrier 8) along slot 5 is illustrated in FIG. 3 and comprises a so-called Tol-o-matic" cable cylinder 16 mounted on the underside of table 2.
  • Cylinder 16 is an air cylinder having mounted therein a piston 17 connected to a pair of cables 18. Each cable extends axially of the cylinder, travelling around a pulley 19 disposed adjacent the relevant end of the latter and is connected to rod 6 by way of a bracket 20.
  • Shaft 21 is hollow and perforated, the exhaust air (which contains oil droplets) from the pneumatic circuit of the machine being delivered into the shaft as can be seen at its lefthand end in FIG. 3 for lubrication purposes.
  • valve V which is visible in FIG. 3, being actuated by a cam 22 mounted on the lower end of rod 6.
  • Valve V is mounted on a screwed spindle 23 and is slidable on a fixed guide rod 24.
  • Spindle 23 carries a knurled knob 25 at its outer end (see also FIGS. 1 and 2), turning of which moves the valve V parallel to the y axis of cylinder 16 when in its rest position so as to vary the position in which the valve is operated.
  • a pointer 26 cooperating with a fixed scale 27 is provided at the front of the casing of the machine (FIG. 1) to indicate the chosen stroke length.
  • the Tol-o-matic cylinder 16 is mounted on the underside of table 2 so as to turn with the latter; in fact the cylinder assembly carries the table.
  • a bearing block 28 is secured to the bottom of cylinder 16 and mounted on a shaft 29 fixed in bearings 29a.
  • pipework 30 connected to respectively opposite ends of the cylinder is also connected to bearing block 28 and, via bores in the latter, to a rotary coupling assembly 31 to which further, stationary pipework (not shown) is connected.
  • the coupling is designed to allow transmission of air from the stationary pipework to the pipework 30 which rotates with the cylinder 16.
  • Rotary movement of the table2 is effected by means of a gear wheel 32 connected to shaft 29.
  • This gear wheel is driven by an air motor 33 having a driving pinion 34 in mesh with its own teeth.
  • the speed of air motor 33 (and hence the speed at which the table turns), is controlled by a second screwed spindle 35 having a knurled knob 36 (visible in FIG. 1) which 0perates a conventional flow regulator valve 37 (FIG. 4) in the supply to the motor.
  • Gear wheel 32 also functions as a sequence controller for the pneumatic circuit of the machine.
  • a number of cams 38 are mounted on the upper surface of gear wheel 32 to control valves V V, V in the pneumatic circuit.
  • Valve V is fixed as can be seen, but valves V and V are carried by a bracket 39 which is pivoted at 40.
  • the position of bracket 39 is controlled from the air motor speed control shaft 35 by way of a sleeve 41 on that shaft connected by a linkage 42 to bracket 39.
  • the purpose of this arrangement is to automatically adjust the positions of the valves V and V in accordance with the motor speed in order to take account of the inertia of the system.
  • FIG. 5 shows diagrammatically the Tol-o-matic cylinder 16, the gear wheel 32 and its driving air motor 33 and spray gun I.
  • a second spray gun is indicated in chain lines for connection to the circuit by way of the associated pair of snap connectors 15!).
  • a four-position rotary switch 43 is provided to control the spray guns as will be explained.
  • Incorporated in the circuit are the valves V, V V and V referred to previously and a foot treadle-operated main control valve V
  • the air supply to the circuit is along line SL.
  • the circuit includes a number of air valves V to V, (some of which are spring return and some air operated as shown), and the two non-return valves NRV.
  • valve V has two effects. Firstly it delivers air to the spray gun I by way of valve V along line L. Secondly, by way of valves V and V, a valve V associated with one end of the Tol-o-matic cylinder is operated. A second similar valve V is associated with the other end of cylinder 16.
  • V therefore connects the righthand end of cylinder 16 to exhaust by way of a valve EV.
  • the exhaust valve EV is adjustable, being controlled by a knob 44 (FIG. 1), to enable the speed of movement of piston 17 to be controlled.
  • Valve V which is connected to supply line SL, then delivers air to a valve V, which is connected to supply line SL. then delivers air to a valve V, whereby the air motor 33 receives air from a separate air supply line SL2 by way of speed control valve 37. This drives gear wheel 32 in the anti-clockwise direction to turn the table 2. Simultaneously, valve V is operated to cut off the air supply to cylinder 16.
  • valve V Operation of valve V connects the air supply line SL to valve V to return this valve to its original position and switch off the air supply to the motor.
  • Valve V returns valve V to the position in which it is shown so that air is delivered to valve V.
  • the cam 38a has operated valve V, it will at this time be in its righthand position and therefore deliver the air from V to valve V
  • valve V is connected to the end of cylinder 16 which is now at the lefthand side by virtue of the construction of coupling 31. Operation of valve V will therefore connect to exhaust the end of cylinder I6 which is at the righthand side and piston 17 will move from left to right.
  • valve V will be operated and the 180 rotation of gear wheel 32 (and hence table 2) will follow as described previously.
  • valves V and V will again be operated by the further cams 38d and 38e respectively.
  • V switches off the air motor 33 as previously and V delivers air to V.
  • Cam 38a is at this time back in the starting position in which it is shown so valve V adopts its left-biassed position. Air is therefore delivered by V along line L3 to switch off the foot treadle-operated valve V and terminate the cycle.
  • valve V is always operated slightly before V This has two ef fects. Firstly, it ensures that the air pulse to operate air cylinder 16 begins before the air motor is switched off, so that there is no pause in the movement of the sole unit support 8 at the end of the first half revolution of table 2, which would cause excess paint to be applied to the unit. Secondly the spray gun I is switched off slightly before the air motor at the end of the machine cycle, again to ensure that no excess paint is applied.
  • valve V referred to above is a manually operable valve by which the spray gun I can be operated without activating the remainder of the circuit. Its operating button is indicated at 45 in FIG. 1.
  • the circuit also includes a push-button operated reset valve V (the operating button being denoted 46 in FIG. 1) which is operated in the event that table 2 is turned out of position for any reason. Operation of valve V connects supply line SL to valve V, which operates the air motor 33 and causes the cycle of operation of the machine to be automatically completed.
  • V the operating button being denoted 46 in FIG. 1
  • Rotary switch 43 is associated with two further valves V, V for controlling the second spray gun.
  • the arrangement is such that, in normal operation with spray gun I only in use, the switch will be set in position 1 or 3. If the switch is set to position 2, the second gun will spray until the end of the second operation of air cylinder 16. Thus, where a shoe platform or forepart is being sprayed, the gun will spray both side edges of the component and the toe edge.
  • An automatic spraying machine comprising: a stationary spraying device; a table which is turnable with respect to said device; a support for a component to be sprayed, the support being carried by a rod which projects upwardly through a diametral slot in the table, and is connected, below the latter, to a piston and cylinder unit carried by the table and. arranged to traverse the rod along the slot for movement of the support in a linear path across the table; and drive means for the table and for the support, whereby, in use, a component to be sprayed can be moved past the spraying. device linearly by movement of the support and in an arcuate path by turning the table.
  • a machine according to claim 1 wherein means are provided to vary the speed of operation of the piston and cylinder unit in accordance with the required speed of movement of the support across the table.
  • the support comprises a pair of slide members which can be adjusted with respect to one another to vary the size of the support to cater for different size components to be sprayed.
  • the table is carried by a rotary shaft and wherein the drive means for the table comprises a'gear wheel mounted on said shaft, and a motor having a driven pinion arranged in mesh with the gear Wheel, the arcuate extent to which the table turns being determined by cams mounted on said gear wheel and associated stationary switches con nected in the power supply to the motor.
