Definitions

  • the invention relates to an apparatus for stacking and sacking concave articles, such as trays, or any like containers of a limited depth, made from foamed plastics foils in a thermoforming apparatus, and the said thermoforming apparatus are provided with multiple molds, which are adapted for thermoforming the concave articles, particularly trays, aligned in more parallel rows.
  • thermoformed concave articles or trays were up to now separated from the foamed plastics foils, and by cutting and turnover devices the same were then stacked within side-by-side arranged parallel channels.
  • a stacked tray-counting device for cyclically actuating a marking device for marking the last concave article or tray in a stack, whenever this stack is formed by a predetermined number of concave articles or trays.
  • the object of the invention is to provide an apparatus particularly for stacking trays, in which the aforementioned sacking operations are entirely automated thanks to the provision of only one tray-sacking machine of known type which is connected thereto, and in which a heat-weldable plastics material web is used.
  • the apparatus of the invention comprises a sack-filling magazine on a channel-conveying device, which is formed by a suitable number of second channels of such a shape and in such an arrangement that the said channels can be set in line with the first channels for stacking the trays, from which they receive the stacks of trays in only one step in which these latter channels are emptied by suitable pushing means which are then neutralized and returned into their cycle-starting position.
  • the said sack-filling magazine on the channel-conveying device has one of its tray-loaded second channels cyclically set in line by its channel-conveying device with the tray-sacking machine and with a pusher by which a stack of trays to be packed in a continuous sack, is introduced into the said machine.
  • the tray-loaded second channels of the sack-filling magazine Once the tray-loaded second channels of the sack-filling magazine have been all emptied, the said sack-filling magazine is returned into its in-line condition with the first channels for stacking the trays, for a successive operative cycle to be repeated.
  • Figures 1 and 2 respectively are a side elevational view and a top plan view of the tray-stacking apparatus according to the invention.
  • Figures 3 and 4 are views in an enlarged scale respectively of the device shown in Figure 1, for driving the tray stacks out of the channels for stacking the trays, and of the pusher shown in Figure 2, for driving the tray stacks out of the sack-filling magazine of the channel-conveying device.
  • Figure 5 is a top plan view of the inlet end of the channels for stacking the trays.
  • Figure 6 is a cross-sectional view of the channels for stacking the trays, taken on line VI-VI in Figure 1.
  • Figure 7 is a front elevational view of the sack-filling magazine on the channel-conveying device, which receives the stacks of trays from the channels for stacking the trays, and cyclically feeds the said tray stacks, one at a time, to the tray-sacking machine.
  • the apparatus comprises a horizontal magazine 1 formed by a plurality of channels C set in a side-by side parallel relation, into which means of known type will stack in an upstanding position on one of their sides, the trays V delivered from the thermoforming apparatus and the cutting means for separating the trays V from the thermoplastic material web from which they are made.
  • the channels C are each provided at the edges of their sidewalls with longitudinally continuous inward projections 42 of one piece therewith or inserted (see figure 6), made from any suitable material which is such or is so treated that an adequate friction will be exerted on the sides of the trays V.
  • the tray-stacking means consist of pushers S which are, for example, actuated by a horizontally arranged pneumatic jack, and are each caused to act in timed relation on the respective trays V, so as to orient these trays vertically and to frictionally insert the same, thanks to the provision of projections 42, into the respective channel C, whereby the trays V are consecutively stacked in the said channels, and are held therein in their upstanding position.
  • the sidewalls 101 of channels C are longitudinally supported by underlying respective beams 2 which at the initial section of the said sidewalls are supported by respective uprights 3 connected to a crosspiece 4 which is made integral with the apparatus frame 5, with the mutual distance between the said uprights 3 being preferably adjustable.
  • Fastened to each beam 2 is also a portion of the bottom wall 201 of each channel C, and the bottom walls 201 of said channels C are each parted into two sections by an elongated, longitudinal median aperture 6, of such a width that the pushing means for driving upon control out of the respective channel C a stack of trays V are each allowed to pass through the said elongated aperture 6.
  • the width of channels C is varied so as to each time make the same conformable to the size of the trays V to be stacked.
  • a device 7 for the pushing means to be rectilinearly and reciprocatingly moved is provided in an intermediate position under the magazine 1, and is arranged parallel to the channels C, and is of a length which is suitably longer than the length of the said magazine.
  • the device 7 is of a type which is available on the market, and comprises a channel-shaped straight body 107 which is secured to the frame 5 of magazine 1 and serves as guide for a small carriage 207 connected to a pneumatic jack for driving the same, and to a belt-and-pulley unit for multiplying its travel, the carriage 207, the pneumatic jack, and the belt-and-pulley unit being all located in the said body 107.
  • the carriage 207 runs under the magazine 1, without interfering therewith, and upon control the said carriage 207 can be moved from its rest position designated by K1, to the position designated by K2 in Figure 1, and vice-versa.
  • the carriage 207 has the intermediate portion of a horizontal crosspiece 8 fixed thereto, which is so long as to extend across the magazine 1 substantially throughout the width thereof.
  • the crosspiece 8 is imparted a to-and-fro movement of such an extent that the same will be driven lengthwise of, and through the entire floor space occupied by the magazine (1), and will be driven out of the said magazine up to be placed at a suitable distance therefrom.
  • the crosspiece 8 rotatably supports a shaft 10 which is parallel to the said crosspiece, is substantially coplanar thereto, and is turned toward the trays V thermoforming apparatus.
  • a rotary actuator 11 is mounted by means of a stirrup onto the crosspiece 8, with a crank 12 being keyed onto its shaft 111 and being caused to cooperate with a lever 13 radially connected with shaft 10, the whole assembly being such that the said shaft 10 can be angularly moved upon control over a suitable angle at first in the one direction and then in the opposite direction of rotation.
  • the pushing means for driving out of magazine 1 the stacks of trays V formed therein consist of duck neck-shaped equal teeth 14 made from a steel strip, which are secured to shaft 10 in an equispaced, coplanar, side-by-side relation.
  • the pushing teeth 14 will be located in their rest position below the magazine 1, which is shown by solid lines in Figure 3, or in their active position shown by dash lines in this Figure, in which through the respective, elongated longitudinal apertures 6 in the bottom walls of channels C, the said teeth 14 are each caused to engage a respective channel C.
  • the said teeth When the pushing teeth 14 are swung into their up position, the said teeth have their flat end portion 114 arranged vertically, and by the said end portion 114 they are each caused to bear against, and to act upon the intermediate area of the internal face of the bottom of the last tray V of a stack formed in the respective channel C.
  • channels C1 which are associated with the upper part of the sack-filling magazine on the channel-conveying device 15, are set longitudinally and coplanarly in-line with the channels C of magazine 1, the length of channels C1 being substantially equal to the length of the said channels C.
  • the channels C1 are provided at the edges of their sidewalls with similar longitudinally continuous inward projections 42 of one piece therewith or inserted, for an adequate friction to be exerted on the sides of the trays V being stacked in the said channels C1, whereby also in channels C1 these trays will be frictionally held in their properly stacked upstanding position.
  • the channels C1 may be each made in only one plate piece, or they may be each made in more than one plate piece, whereby their width is adjustable so as to cause the same to conform to the cross-section of channels C.
  • these channels can be predisposed for being easily and quickly replaced so as to have the same adapted to the size of trays V.
  • the channels C1 are suitably cantilevered by their end which is turned toward the magazine 1, and are transversely supported at their bottom by the chains 115, 215 of the channel-conveying device 15, which are led over respective pinions 16, 116 keyed onto the ends of a pair of parallel shafts 17, 117, which in turn are supported by a base frame 18, with the tensioning of said chains being adjustable by the means shown at 19 in Figure 7.
  • One of the said shafts, the shaft 17 for example, has its one end connected by means of a positive motion transmission drive, such as a chain-and-pinions unit 20, to a driving unit 21 fitted on the said frame 18, with the chain of unit 20 being stretchable.
  • the parallel branches of chains 115, 215 of the channel-conveying device 15 are supported by respective stationary straight guides 22, 122, particularly in order to ensure that the upper channels C1 will be held as required in their coplanar and in-line condition to and with the channels C of magazine 1.
  • the length of the rectilinear branches of the chains 115, 215 of the channel-conveying device 15 is greater than the width of magazine 1, and is so provided that the said branches will suitably project from the said magazine side on which a straight pusher 23 is arranged, which when in rest position is located outside of the floor space occupied by the channel-conveying device 15, as shown by solid lines in Figure 2.
  • the pusher 23 is located over the ideal horizontal plane containing the bottom of those channels C1 which are associated with the upper branches of the chains 115, 215 of the channel-conveying device 15, and the said pusher is attached to the one end of a suitably long horizontal rod 24 which by its opposite end is made integral with a transverse arm 25 shaped like an upturned “L”, which in turn is connected in a cantilevered manner to a small carriage 26 being caused to run with its grooved wheels 27 on a rail 28 secured to one side of a structural shape support 29, and arranged parallel to the said rod 24 and to the longitudinal axis of channels C, C1 (see also Figure 4).
  • the horizontal section of the said upturned L-shaped transverse arm 25 is located over the ideal horizontal plane containing the upper edges of those channels C which are associated with the upper branches of the chains 115, 215 of the channel-conveying device 15, so that the said horizontal section of arm 25 does not interfere with the upper edges of said channels C.
  • the support 29 is carried by a frame 30 which is attached to the base frames 5, 18 of magazine 1 and the channel-conveying device 15.
  • the assembly 28, 29 is so long as to allow the pusher 23 to be moved upon control from its rest position shown by solid lines in Figure 2, to the limit of its active stroke shown by dash lines in this Figure.
  • the pusher 23 is moved through the whole floor space occupied by the channel-conveying device 15, and out therefrom with a suitably long section, as required for the same to be passed through the station 31 in a tray-sacking machine 32, in which a thermoplastic material web is made tubular, and to be positioned downstream of a welding and cutting station 33 in the same machine.
  • toothed pulleys 34, 134 are rotatably fitted on the ends of the structural shape support 29, with their horizontally arranged shafts being parallel to each other and being perpendicular to the said support.
  • a toothed belt 35 is led over the said pulleys 34, 134, with an integral extension 36 of carriage 26 being fastened to the upper branch thereof.
  • the shaft of one of the said toothed pulleys 34, 134 is keyed onto the slow shaft of a geared motor 37 which runs in either directions of rotation, and may be at two speeds, and is provided for imparting the required reciprocating motion to the aforementioned pusher 23.
  • the return stroke of pusher 23 may be carried out at a higher speed than its forward stroke.
  • end-of-stroke microcontacts 38, 138 are provided ( Figures 4 and 7), which are fitted on brackets 39, 139 fastened to the structural shape support 29, and are arranged for an alternate cooperation with the two opposite profiles of a cam 40 secured to the extension 36 of carriage 26.
  • the tray-sacking machine 32 is a unit of a type which is available on the market, in which only one roll of a thermoplastic material web is used, which is made tubular and is longitudinally welded in station 31, so that a continuous sack is formed, having the required width dimension for containing a stack of trays V.
  • station 33 the continuous sack into which a tray stack is packed, is provided with two transverse, relatively close parallel weldings, between which it is cut. Both the welding of the top end of the tray-filled sack portion and the bottom welding of the just formed continuous sack, as well as the separation of the filled sack portion are thus achieved.
  • the pushing teeth 14 are caused to partly get into the channels C1, which for this purpose are each formed at the inlet end of the respective bottom wall, with an intermediate opening 41.
  • the unit 21 for driving the channel-conveying device 15 is intermittently actuated, whereby a tray-loaded channel C1 comes to be each time set in line with the pusher 23.
  • Such an in-line condition is signalled by a sensor, not shown in the drawings, since this is conceivable and easily practicable by those skilled in the art.
  • the motor unit 37 is actuated, whereby the pusher 23 is imparted its reciprocating stroke, as required for transferring the stack of trays V having been set in line therewith, from the respective channel C1 to the tray-sacking machine 32 for packing the said tray stack into a continuous sack of thermoplastic material.
  • the channel-conveying device 15 is re-actuated, whereby a successive tray-stack-loaded channel C1 comes to be positioned in front of the said pusher 23, the described cycle being repeated until all the previously loaded channels C1 are emptied.
