Definitions

  • the invention relates to an apparatus for closing boxes comprising means for bringing a box between two vertically arranged transport belts which are moved to engage side walls of a box the four top flaps of which are open, and whereafter the said transport belts move the box centrally to a bridge the height of which is adjustable and which is provided with flap closing members and a sensing member, which said sensing member on the engagement thereof with a fore wall of the box when the bridge is in its lowest position operates means to cause raising of the said bridge until the said sensing member comes into engagement with a fore wall flap of the box, which said fore wall flap is closed by further movement of the box, and in which the bridge is provided with an arm for closing the side flaps thereafter.
  • the bridge is provided with fixed mombers thereon for closing the side wall flaps of the box.
  • These members have the form of bent rails and the foremost portions of which are bent downward and outward so that these will lie under the side flere after the fore flap has beer closed and the box is moved further forward. Due to the fact that the foremost portions of the rail-like members extend inward, the upper flaps of the box are closed thereby.
  • the boxes for closing must have a certain width.
  • the free ends of the foremost portions of the side flap closing members will lie under these flaps and especially when they hang outward and downward from the sides of the box.
  • the means for closing the side flaps of the box are formed by movable arms which are arranged on and extend downward at an angle from the bridge and which, together with the transport belts, are moved toward the box and lie directly above the transport belts when the bridge is at its lowest point and such that on a following upward movement of the bridge the side flaps of the box are brought into positions by the said movable arms in which the said side flaps are directed outward and upward at an angle, and in which the bridge further comprises members which come into operation after the closing of the fore and rear flaps of the box and which exercise such movements that they engage the side flaps substantially along the longitudinal edges thereof to push these longitudinal edges toward one another and toward the top surface of the box.
  • the closing of the side flaps takes place immediately after closure of the fore flap which is effected by movement of the box under the sensing member of the bridge.
  • This sensing member simultaneously energizes the members for closing the rear flap. Due to the fact that closure of the side flaps takes place independently of box lenth, it is possible to have a considerably shorter apparatus and a higher throughput speed for the boxes, and this jointly because the fore edges of the side fleps are not pushed up against fixed members.
  • the members pushing the side flaps into the olosed position are formed by rods arranged approximately parallel to one another in the direction of movement of the boxes, each of which rods is affixed to a footpiece which is pivotably mounted on the end oi an arm the other end of which is pivotably connected to the bridge, and in which means are provided between each of the footpieces and the relating arm, through which the footpieces and therethrough the closing members are moved substantially parallel to one another through the downward movement of the rods toward the center of the box, and which movement is obtained by the position adopted by the spindles on which the arms pivot and which position is at an angle to the vertical.
  • the pivotable arm arranged on the bridge piece for closing the rear flap of the box, is also pivotable in the horizontal plane from a stance, when the bridge piece is in its lowest position, in which it lies out of the vertical plane of the transport belt present on the side thereto, to one in which a portion thereof lies against the rear wall of the box being fed for closure and which portion moves upward along the rear wall of the box as the bridge moves upward.
  • this portion of the arm which comes to lie against the outer rear wall of the box to be closed, forms part of a wing-member which is pivotable in respect of the arm which is pivotable connected to the bridge about an axis lying in a horizontal plane and substantially parallel with the rear wall of the box when the wing-member is in its operative position, and which wing-member in this position is inclined at an angle downward toward the rear wall of the box and in which driving means are provided by which, after the bridge has reached its highest position, the wing-member is pivoted in such a manner that the portion thereof extending outward above the spindle of the wing closes the rear flap of the box.
  • the lower portion of the wing-member ensures thus that the rear flap is brought from a position in which it extends at an angle downward to a position in which it extends at an angle upwards and whereafter, when the bridge is in its highest position, the wing-member operates directly to effect closure of the rear flap of the box.
  • the wing-member is mainly in the form of a flat plate which is arranged substantially parallel to the spindle on which it pivots and which at some distance below this spindle, when viewed in the condition in which the wing-member lies against the rear wall of a box, shows a small bend such that the portion thereof inclined toward the box makes a smaller angle to the horizontal plane than the other portion thereof.
  • the wing-member In order to ensure that the pivoting of the wing-member can only take place when the lower edge thereof positively lies against the rear wall of a box and only when the bridge has been raised to its highest position, the wing-member is driven by a coupling which permits the wing-member to make a small free movement and such that when it comes into engagement with the rear wall of the box the wing-member is turned a little, and which turning movement provides a first signal for pivoting the wing-member to close the rear flap but which turning movement only occurs when a second signal is provided when the bridge has reached its highest position.
  • the sensing member provided on the bridge can be of such a design that after tie bridge has reached the highest position in its upward movement and the box is beginning to move further the sensing member can exercise a pivoting movement about an axis which is horizontally arranged parallel with the fore wall of the box, and through which pivoting movement the sensing member coacts with a closing rail which is movable in the vertical direction with respect to the bridge, and which comes to rest on the fore flap of the box to close it.
  • the sensing member is formed by a roller which is affixed to a rail which, in turn, is affixed to the bridge.
  • the weight of the rail can always be utilized to effect closure of the fore flap of the box.
  • the construction may be such, however, that the closing rail coacts with regulating means connected to the bridge whereby the closing rail also comes to rest on the box with a certain force.
  • control means therefor can be constituted by a slide valve the members of which are displaced one with respect to the other by movement of the closing rail with respect to the bridge, and which said slide-valve is included in the control system lines of the pneumatic-hydraulic means.
  • centering of the box is achieved by bringing the transport belts simultaneously into engagement with the box from each of the sides thereof.
  • the centering of the box with respect to the bridge must take place within the apparatus itself, and means for achieving this must be present which check whether both the transport belts are lying in engagement with the box, and only after which can the bridge be permitted to move upward.
  • Such an operating condition is naturally not in the interests of the operating speed of the apparatus.
  • an apparatus which is characterized by the provision of means for centering a box fed thereto before it is fed between the transport belts, which means comprises a number of driven spindles arranged one after another and on which there are mounted roller blocks from the outer peripheral surfaces of which other rollers of barrel form extend for free rotation on spindles therefor, and which said barrel roller spindles are arranged in the first said rollers at right angles to the said driven spindles therefor and spaced at a distance therefrom, and at least two pairs of arms arranged above the said driven spindles and pivotable in the horizontal plane about the axes of spindles particular thereto which are arranged near the sides of the box feeding means, and which said arms are coupled in pairs such that they simultaneously pivot inward or outward and for which spring means are provided to always urge the said arms to adopt their innermost positions in which they are directed to converge somewhat forward toward the bridge to close off the greater part of the passage therethrough for the box.
  • both arms will pivot away to allow passage of the box therebetween.
  • a contact member can be provided behind a somewhat flexible portion of one belt which is operative to ensure that the transport belts come into engagement with the box with a predetermined force.
  • the transport belts can be used directly to effect forward movement of the box without the necessity of being provided with catches by which the box is carried along and such as is the case in the known apparatus.
  • the transport belts By the use of such box engaging catches the transport belts must always be moved a certain distance before such catches can come into engagement with a box. This condition is particularly valid when short boxes are transported through the apparatus because the catches must be arranged at such a distance from one another that the longest of the boxes to be transported can be accomodated therebetween.
  • a box is directly transported by the transport belts as soon as the transport belts are pushed into engagement therewith such that the box is pushed into engagement with the sensing member on the bridge.
  • a predetermined adjustment of the contact member arranged behind one of the transport belts is possible so that further lateral movement inward of these transport belts is prevented when they have engaged the box with a certain force.
  • the boxes are centralized by transport rails, and wherein thus one rail must always care for the lateral displacement of a box until it also lies in contact with the other rail.
  • the closed flaps of a box can be sealed with the aid of a strip of adhesive tape drawn off a supply roll thereof.
  • a strip of adhesive tape drawn off a supply roll thereof.
  • the checking means is constituted by a feeler which is arranged in the path of the adhesive tape between the supply roll and the free end thereof which has been affixed to a box, and such that in the presence of adhesive tape the feeler is somewhat displaced thereby to cooperate with switching means by which the apparatus is maintained in operation.
  • the switching means cooperating with the feeler can be activated with the aid of the pivoting movement of a carrier to which the free end of the adhesive tape is affixed, and which pivoting movement is originated by an oncoming box engaging the adhesive side of the tape which is then moved with the box and is withdrawn from the supply roll thereof.
  • the adhesive tape comes into engagement with the feeler and the feeler is displaced in such a manner that the apparatus is maintained in operation. If the adhesive tape now breaks, or the supply thereof from the roll runs out, the tension in the adhesive tape will fall away with the result that the feeler will no longer be held in its active position and will effect switching-off of the apparatus, When a box has had the adhesive tape applied thereto in the correct manner and the taping process therefor is completed, the foregoingly quoted carrier is relased and thereafter first taxes care that the feeler is rendered non-operative before the adhesive tape is severed and the tension therein falls away.
  • the apparatus comprises a box centering and transporting section generally indicated by the reference numeral 1, a box closing section 2, and a box sealing section 3.
  • Section 1 of the apparatus comprises a frame 4 which serves to support the spindles 5 on which rollers 6 are accomodated such that a box fed thereto can be transported thereby in the direction indicated by the arrow P1.
  • the rollers 6 also accomodate rollers of barrel form 7 therein the axes of which are disposed at right angles to the axes of the spindles 5. This arrangement makes it possible for a box, fed over the rolls 6, also to be moved easily in the direction indicated by the arrow 12.
  • the frame 4 further accomodates 2 pairs of pivotable arms 8 mounted therein, nach of the arms 8 is carried by a spindle 9 in fixed relationship therewith, whilst each of the spindles 9 is fixed to a lever arm 10.
  • a coupling rod 11 is pivotably mounted to the extremities of the lever arm 10 so that the arms 8 can exercise pivoting motions which are symmetrical in relation to the centerline of the apparatus as a whole.
  • One of the spindles 9 is provided with a lever arm 10 the other end of which is attached to a tension spring 12 the other end of which is fixed to the frame 4, and in such a manner that the arms 8 are urged to take up their innermost positions.
  • rollers 6 are driven via the spindles 5 which are provided with sprocket-wheels 15 engaged by the chain 16.
  • One of the sprindles 5 is driven by an electric motor or the chain 16 runs over a sprocket-wheel provided to the shaft of the motor.
  • Section 2 of the apparatus comprises a frame 21 in which transporting rollers 22 of a conveyor are supported for rotation therein.
  • Rollers 22a, 22b and 22c can exercise the functions of switch operating rollers. To this end they can be mounted in such a manner that they are spring urged vertically upward so as to extend above the surface of the other rollers, when a particular roller is forced downward by a box passing thereover a switch is operated.
  • rollers 22 and the parts of the frame serving to support these rollers guide rods 23 are arranged in the frame 21.
  • These guide rods 23 are provided with bushes 24 thereon, and which bushes 24 are in turn affixed to plates 25 which are, again in turn, affixed to transport belt supporting members 26.
  • the transport belt supporting members extend in the longitudinal direction of the frame 21 on both sides thereof.
  • the supporting members 26 carry spindles 27 accomodating rollers 28 thereon, over which transport belts 29 run.
  • the transport belts 29 can be displaced laterally, from the positions in which they are in the position of rest as depicted in fig. 1, inwardly to a position in which they come into engagement with a box as shown in fig.
  • this lateral positioning is achieved by means of the bushes 24 and the guide rods 23.
  • the plates 25, connecting the bushes 24 with the supporting members 26, can move between certain ones of the rollers 22, as indicated by the reference numeral 30 for example, and at which position parts of the frame supporting the rollers 22 are shown broken away.
  • the displacement of the transport belts is effected by means of a pneumatically operated cylinder which is operatively coupled to cne of the bushes 24 or to one of the plates 25 for example.
  • the transport belts 29 move simultaneously inward over the same distances, they can be coupled at their fore and rear ends by chains which extend laterally therebetween and which engage sprocket wheels which are rotatably accomodated at fixed positions on the frame.
  • Each of the two parallel running parts of the chain is coupled to one of the bushes 24 so that, on displacement of one bush over a certain distance inwards, the corresponding bush exercises a movement over the same distance.
  • Such a system is further to be described herein, because this system is adapted to other parts of the apparatus.
  • Such a chain is provided ior the fore end of the transport belts 29 as well as the rear end and for parallel guidance thereof, for example one sprocket wheel of the forward part can be coupled to the sprocket wheel of the rearward part of the transport belts 29.
  • use can be made of a single chain which operatively engages with a number of supplementary sprocket wheels.
  • Section 2 of the apparatus further comprises a portal 31 the vertical columns 32 of which serve to guide the vertical movements of the bridge 33 upward and downward.
  • the bridge can be supported by ball bearing bushes which run on a hardened shaft, but naturally rack-and pinion devices can be employed as will be evident to the expert.
  • the upward and downward movements of the bridge can be effected by means of hydraulic-pneumatic cylinders.
  • the bridge 33 is provided with a sensing member 34 which is movable affixed thereto.
  • This sensing member 34 is pivotably mounted on an arm 36 via a spindle 35, which arm 36 is coupled, via two pivotable connecting members 37, to a carrier 38 which is in turn carried by the bridge 33 in fixed relationship therewith.
  • the arm 36 In its unloaded condition, the arm 36 will substantially assume the position in which it is shown in fig. 4 by its own weight.
  • two guide rods 39 are arranged on the bridge 33, and on which guide rods 39 two support plates 40 are slidably accomodated.
  • An operating cylinder 41 is mounted in operative relationship to one of the support plates 40, whilst displacement of the support plates is synchronized by means of a chain 42 which engages sprocket wheels 43 which are supported for rotation at fixed points on the bridge to at one point along its lenth, the chain 42 is affived of the support plates 40 at the point designa- tud by the reference numeral 44, whilst at another point along its length the chain 42 is affixed to the other one of the support plates 40 at the point designated 45.
  • a staff-like arm 46 is affixed to each one of the support plates 40 and by means of, for example, block-like members 47, through which the position of the arms 46 can be set and locked against movement therefrom.
  • These arms 46 are provided with triangular plates 48 on the free ends thereof and the under edges 49 of which lie somewhat above the corresponding transport belt 29 when the apparatus is in the rest condition.

  • a chain 60 engages each one of the sprocket wheels 57 and further engages another sprocket wheel 61 which is affixed to the bush 52.
  • the chain 60 and the sprocket wheels 57 and 61 ensure that, during the pivoting movements of the arms 50, the closing members 59 move in such a manner that the longitudinal axes thereof still move parallel to the longitudinal axis of the closing apparatus.
  • the chain can be provided with a not shown tensioning device. It will also be clear that the chain 60 and sprocket wheels 57 and 61 can be replaced by a system of levers with a coupling rod therebetween.

  • a switch 29a which is arranged behind one of the transport belts 29 such that it pushes the belt somewhat outward toward the box.
  • compressed air at a regulated reduced pressure is fed to the pneumatically operated cylinder and through this the transport belts 29 are held againnt the box 13 with the desired amount of pressure.
  • the transport belts 29 carry the box 13 forward with them because at the same time as the cylinder is operated to bring the transport belt together, the transport belts are set into motion by motors (not shown) which drive the rear shafts 27 of the rollers 28.
  • the transport belts 29 will be rubber belts provided with a series of vertically arranged ribs which will effect positive carrying of the box with then.

  • the sensing member 34 As soon as the sensing member 34 has reached the upper edge of the fixed front surface of the box 13, the sensing member with the arm 36 will move somewhat back in the direction opposite to the arrow P3, mainly in consequence of its weight, by which movement the switch 38a is operated again and the transport belts are put into operation again to push the box 13 through under the arm 36 and the bridge 33. During this movement the front flap 13b of the box 13 is pushed downward onto the box as indicated in fig. 2.
  • both the switches operated by these rollers effect feeding of compressed air to the cylinder which operates to impart movement to the chain 67 accomodated on the carrier 62.

  • the bridge 33 With a length of box greater than that for which the apparatus has been designed, the bridge 33 can already be raised before the lower part of the closing wing 73 pivots toward the rear wall. The rear flap must then be in such a position that it cannot be pushed against the rear wall of the box by the closing wing.
  • the switch 76a signals, however, that the closing wing lies against the box, and when the sensing member 34 now emerges out from over the box in the manner previously described and through which the arm 36 reverts back to its original position, another switch is operated which effects the supply of compressed air to the cylinder 80 which, in turn, effects movement of the chain 78 and through which the closing wing 73 will be pivoted leftward as shown in fig. 5.
  • the closing wing 73 then assumes the position as shown in fig. 2, and in its movement closes the rear flap 13c of the box. This movement takes place rapidly since the rear flap must be closed before tie box has proceeded too far under the sensing member 34 otherwise the rear flap 13c would engage this sensing member.
  • the cycle can then be repeated again.

  • the cutting member 135 can also return to its original position whereby the adhesive tape 107 is severed, Whilst through springing back of the arm 117, the roller 137 will move up along the rear wall of the box 13 to firmly press the severed free end of the adhesive tape against the box.
