Description

The present invention relates generally to

  automatic transport systems and more

  particularly a sophisticated automated transport system

  type having a guide portion which

  obliquely, and supports moving freely

  and which circulate on this part forming a guide, the person

  according to the invention relating to a device which limits the movement of the supports forward on

  the part forming a guide descending obliquely and on

  very guide parts that are not inclined.

  Self-contained transport systems can be used

  matted, of the type to which the present invention refers,

  in a garment factory, for the purpose of

  to carry work pieces to a series of pos-

  work, where different operations are performed,

  or to storage areas. Such a system of trans-

  port is described in a pending US patent application, Serial No. 683,379, filed on 19.12.1984 at

  name of Roald Paul Nymark and Harold Osthus. The system men-

  previously is highly automated and includes freely movable carts which support workpieces, and a network of rails on which the carriages run and which has a main rail and

  rails forming secondary loops. The main rail

  cipal guides the trolleys to the rails forming

  secondary keys and these loops guide the trolley

  and from workstations or serve as storage areas. The rail network also includes an endless mobile chain located in the vicinity of the rail

  and pushers attached to this chain and

  along the latter so as to contact the carriages and to drive them along the main rail, and

  switching devices for carrying out the transmission

  trolleys to and from the rails

storing secondary loops.

  Each of the secondary loops has a zonal

  in the vicinity of the main rail and,

  Likewise, the main rail has an interrup-

  in the vicinity of each secondary loop, and the

  its associated switching element comprises a short rail element and an actuating device which is able to move

  the rail element from a first position, in which

  it fills the area of interruption of the main rail, jus-

  only in a second position in which it fills the interrupt zone present in the secondary loop and vice versa. To carry out the transfer by switching a carriage from the main rail to a rail forming

  a secondary loop, the rail element is located initially

  in the main rail interruption area and re-

  a trolley driven by a pusher. Then the

  actuating device moves the rail element, while the carriage is located on the latter, to bring it into the interruption zone situated in the secondary loop and the

  pusher drives the trolley on a rail constituting the

secondary school.

  Another rack and rail system includes

  a main rail, rails forming secondary loops

  res and a switching device located in the vicinity of

  each secondary loop, trolleys moving freely-

  on the rails, and pushers for the trolleys. Each switching device comprises a pair of pivoting fingers whose axes of rotation are located on the main rail. When both fingers

  swivels are closed, a trolley is guided on the

  switching device along the main rail and,

  that a pivoting finger is open, a carriage is guided towards the secondary loop or is received by the latter. In both types of trolley and rail systems described above, a computer is used to

  order the transport of the trolleys to the loops se-

  and carry out this work by commanding the

  me of switching associated with them. To achieve a

  correct switching operation, moving the dis-

  positive switching must be synchronized with the

  the designated trolley, and the computer evaluates the posi-

  trolley mainly from the position of

  his pusher. With one or other of the types of

  switching factors described above and with other types of

  of switching devices, it exists at any time

  either in the main rail or in the se-

  conditionality, discontinuities which have the effect of

  riot can inadvertently fall from the rail network.

  To solve the problem, it is sometimes advantageous to provide secondary loops used

  for storage, at a level located a few meters

  above the floor so as to maintain a working space

  the space below the storage loops can be used for workstations, storage areas, passages or other purposes, in which case at least a portion of the rail network oblique position and at least a part of this network goes down obliquely. Similarly, such automated transport systems can occupy two floors of a plant, in which case at least a portion of the rail network rises obliquely and at least a portion of this network descends obliquely to connect the two

  floors. If a carriage moving freely, without

  tation, travels on such an inclined descending part of a network of rails, the carriage rolls forward

  push and go down along the inclined rails part

  to the rear of the next pusher, which is typically between 0.9 and 1.5 meters downstream. If the rail element inclined

  down is located just downstream of a communication device

  mutation programmed to deflect the truck, and if the pusher does not catch on the truck before reaching

  the switching device, the truck can pass

  the switching mechanism before the computer controls the switching device to move the secondary loop, and therefore may not be

  subject to the switching operation. Similarly in the system

  of the aforementioned US patent application,

  it is also possible that the carriage directly

  forward of the wagon is programmed to be directed to the secondary loop, and that the wandering cart falls off the rail into the gap that remains when

  the switching mechanism tends to switch the chain

  riot located upstream or that the wandering carriage is

  inadvertently subsequently transferred to a

  work or an unscheduled storage area,

or block the system.

  Outside the downward slope of an element

  of rail, there are other factors that lead to

  this of a carriage in front of its pusher, and which pose

  possibly problems of the type described above.

  For example a draft of air produced by a door or an open window can act on the clothes hanging on the trolley, in the manner of the wind acting on a sail, a person can inadvertently push a trolley

  associated workpieces, or an opera-

  loading a truck onto the rails may inadvertently

  push the carriage forward.

  This is why a general goal of this

  The invention is to improve a transport system of the type comprising freely moving supports, a guide for the supports and pushers for the supports, so that the latter can not advance a considerable distance ahead of the pushers, which associated with them, when pushed back in that direction

  under the action of gravity or other force

this outdoor.

  A more specific object of the invention is to provide

  a development that is simple in its constitution and use, and does not significantly interfere

  the routing of media in the system.

  Other objects and advantages of the invention are

  will come out clearly from the detailed description given

  hereinafter and the appended claims.

  The invention lies in the fact of providing limiting means for a transport system of the type

  having a plurality of free-moving carriers

  a guide for media and training materials.

  supports along the guide. According to a characteristic of the invention, the drive means comprise an endless mobile chain and pushers

  which extend from the chain and lead to the

  ports, and the means of limitation include a

  of lugs that extend downwards from the

  chain, a lug located in front of each push-button

  a reception area to receive a

  Harbor. According to another feature of the invention

  each lug is mounted so that it can be

  vote, on the string inside limits defining a position of charge to let a support penetrate

  in the space of reception of the support and a position of

  cage preventing the support from coming out of this space.

  According to another characteristic of the

  vention, each limiting pin is fixed, so

detachable, to the chain.

  Other features and advantages of the pre-

  invention will emerge from the description given below.

  automated transport system of Figure 1.

  Referring now to the drawings, it will be seen that FIG. 1 shows an automated transport system generally designated 5 and embodying the present invention. This system comprises

  a pilot computer 8, a displacement track 10 com-

  carrying pushers 15 extending downwards, a unit

  motor drive unit 3 provided for the track of de-

  placement 10, a main rail 12 located below the

  driving track 10, carriages 14 moving freely

  nly, circulating on the rail 12 and driven by the pushers 15, and secondary loops 16, 32, 17 and 19 located along the main rail, along which they are matched. Each of the secondary loops 16 and 32 extends towards and from a workstation 33 or 35, and the secondary loops 17 and 19 are used.

  for storage. The automated transportation system

  additionally carries three switchgear devices

  for transporting trolleys between the main rail

  cipal and each pair of secondary loops or di-

  rightly between the secondary loops of a given couple

  born, and two position switching devices 27 for

  conveying the trolleys between the main rail and each

  unmatched secondary loop or a deflection rail 31

  tion. The system of Figure 1 comprises a set of

  nine secondary loops, but can easily be modified

  to include more or less

  large number of loops, if desired.

  Fig. 2 shows a section of the automated transport system 5 of Fig. 1 and shows the

  main rail 12, the traveling track 10 located at

  top of the main rail and a couple of sec-

  16 and 32. One of the trolleys 14, spotted in particular

  14a, runs on the main rail 12 and is

  driven by one of the pushers 15 identified specifically

  by 15a. The pusher 15a is part of a series of identical pushers uniformly distributed along the

  lane 10 and extending downwards from this last

  Niere. The pusher 15a itself is driven by a chai

  endless moving wheel (FIGS. 8 and 9) located inside the displacement track 10 arranged in overhang and, in FIG. 1, the pusher is shown as driving

  the carriage 14a towards the secondary loop 16.

  A series of limiting lugs 70 also extend downward from the lane 10, a lug being located in front of each of the lugs 15. The secondary buckle

  16 comprises a loop rail 28, a stop 38 and a

  54, and the secondary loop 32 on the side

  opposite represents the symmetry of the loop 16.

  The main rail 12, the secondary loop 16 and the

  Secondary unit 32 has interrupt zones which are laterally aligned with each other, and the switching device 25 comprises a rectilinear rail element 24 and a computer controlled actuation device 18. The main rail 12, the rail element 24 and the loop rails 28 and 30

  are preferably constituted by tubes. The action device

  18 is responsible for the lateral displacement of the rail element 24 between a first position (as shown), in which this rail element fills the interruption zone present in the secondary loop 16, a second position in which it fills the interruption zone 19 has in the main rail 12, and a third position, in which it fills an interruption zone (not shown) present in the loop

secondary 32.

  initially in the rail interruption zone

  key and one of the pushers 15 pushes a carriage

  then the main rail 12 on the rail element 24. Then the computer controls the actuating device 18 to move the rail element 24 towards the area

  interrupting the secondary loop 28. Although the

  riot be located on the rail element 24, the pusher 15

  continue to contact the cart since the

  evening is wide and when the rail element reaches the zoo

  With the interruption of the secondary loop 16, the pusher pushes the trolley onto an input portion 36 of the loop rail 28. Then the actuating device 18 brings the rail element 24 back to the main rail 12 so that other carriages may descend along the main rail or be switched by the rail switch station. The looped tube 28 of the secondary loop 16

  tilts down from its introductory element

  tion 36 so that a carriage circulates on this tube under

  gravity. About half way along the loop rail 28 is the stop device

  38 which has an upper door and a lower door

  (none of which is shown). The device for

  Rét 38 is represented as supporting carriages 14b-

  d at its upper door, the carriage 14b being the first of this suite. There, the carriage 14b waits for the operator 42 to be ready and pushes a button located on the control box 50 so as to open the door

  upstream of the stopping device 38 and to enable said chain

  riot to circulate towards the downstream gate located at

  the base of the stopping device 38, in the vicinity of the

  as has been the case previously for the

riot 14th.

  In Fig. 2, the operator 42 is shown as performing a seam on a work piece

  46 carried by the carriage 14e, by means of a cutting machine

  45, and when this work was done on all

  the workpieces suspended on the trolley, it can

  push a button located on the control box 50 to cause the opening of the downstream door of the stop device 38 and to allow the carriage 14e to go down under

  the action of gravity towards the elevator 54.

  At the base of the elevator 54 is disposed

  another stop device (not shown) serving to

  lecter the carriages while they wait their turn to be loaded again on the main rail 12. When the pilot computer detects a lack of carriages on the rail element 24 and a portion of the main rail

  12 located immediately upstream of the rail element 24, it

  last brings the rail element 24 to the loop sec-

  driver and the elevator 54 to admit a truck

  in a forklift, which includes a piston element

  slotted 57 serving to receive the carriage. When the computer controls the elevator so that it raises the

  trolley as was done for the carriage 14 re-

  f by f in Figure 1, and once the carriage has

  reached the upper part of the elevator 54, the

  immediately following evening, who arrives, pushes back the

  riot out of the slotted runway element 57 to bring it

on the rail element 24.

  According to a mode of operation, once

  the rail element 24 has received the trolley, the computer

  command the actuating device 18 to bring it back

  the rail element 24 in a position aligned with the main rail

  12 and, after a short period of time during the

  which the carriage has been pushed, the latter returns to the main rail 12 and moves downstream, usually towards another secondary loop and a station

associated work.

  Figure 3 shows that secondary loops

  17 and 19 are elevated to a significant height

  port to the secondary loop 16 and to the workstation as-

  and are, for example, 2.4 meters above the secondary loop 16. This is intended to save

  the workspace; storage loops, chases

  stored rots and workpieces 50 are sufficient

  trained in height to allow people to

  to circulate or work below them, to

  put to other work pieces or equipment

  to be disposed below them or to allow the execution

  other functions below them. Part of

  downward slider 90 of the rail 12 extends from the loop

  secondary 19, to the secondary loop 16.

  the carriage and enclose the rail on which they are

  slow to establish a balance. In the upper part

  14n of the trolley is arranged a part of

  T-shaped 66 which is the part of the carriage which is actually contacted by the pusher 15c. The pusher c has an inverted T shape and extends downwardly from the inner face of the displacement track, behind the carriage 14n (relative to the direction of movement of the carriage on the main rail), and inside the track, an endless mobile chain 150 is connected to the pusher 15c and drives the latter. Similarly, the limiting lug 70 is fixed to the chain 150 and is driven by the latter, this lug

  being located in front of the 14n trolley.

  Focusing now on this

  vention, we see that Figures 5, 6 and 7 illustrate the

  limiting taste 70, which is made of a metal or a plastic material and has a shaped portion

  rod 72, a neck portion 74, a portion in form

throat 79 and a curved head portion 76 comprising

  both a rear portion 82 and a recess 78 which may

  turn on a pivot. For example, ergot 70 is

  molded aluminum and has the dimensions

  vantes: A = 0.63 cm B = 8.25 cm C = 6.59 cm D = 0.51 cm E = 4.13 cm F = 0.66 cm G = 2.32 cm H = 0.79 cm (diameter) I = 2.54 cm J = 0.82 cm (diameter) K = 30 degrees L = 1.43 cm (radius) M = 0.79 cm N = 4.13 cm O = 9 degrees P = 0 , 48 cm Q = 1.43 cm

R = 0.32 cm (radius).

  Similarly, the vertical distance between the chain 150 and the rails 12 and 24 is such that when the pin is suspended from the chain, it extends just below

  the head portion 150 of a carriage 14, which it limits.

  Figures 8 and 9 show the chain 150 of the displacement track 10 and the limiting lugs 70. The chain comprises connecting members 170 and 172,

  the connecting member 170 being connected to the link member

  172 sound via a horizontal pin 176

  and a vertical pin 178 to allow rotation

  vertical relative rotation and a relative rotation

  zontal, which are required to follow the trajectory of the main track 10. The chain 150 further comprises vertical rollers 180 mounted on axes 80 and horizontal rollers 182 mounted on pins 184, which wheels guide the chain inside. of

  the main track 10. The lug 70 is connected, in a de-

  tachable, by means of a snap-fitting assembly, to the horizontal axis 80 of the chain, the recesses 78 cantouaer on a pivot engulfing the axis at the neck 79, while the lug 70 pivots on the axis . Due to the design and dimensions of the type indicated above of the lug 70, the lug 70 itself is balanced by placing itself in the orientation shown in FIG. 8,

  the rod-shaped portion 72 of the lug forming an annulus

  approximately 45 degrees to the horizontal plane.

  In the embodiment shown, a

  pins 70 is disposed in front of each pusher as-

  company and, for example, the separation distance is equal to about 20 centimeters. This space defines a

  housing 86 for the carriage and can accommodate, in the

  seems of its volume, a trolley, while being sufficiently

  short to allow the computer to be reasonably

  informed about the cart.

  The lug 70 can pivot backward (in the direction

  counterclockwise) to a positive position

  charge of the truck, in which the part in

  rod 72 is oriented approximately horizontally

  and is in abutment against the link member 82 of the chain 150, and can pivot forwards (clockwise) into a locking position of the carriage, in which the shaped part of

  stem is oriented approximately vertically and the

  the rear portion 82 of the head portion 66 abuts against

  to be a spacer 84. To load a truck into the

  space 86 of a carriage, it is possible to insert

  trolley on a portion of the rail inside the housing or insert it on a portion of the rail in front of the associated limiting pin 70 and either hold it in

  place until the pin 74 catches the carriage and pivots

  vote up to come into the position of charge-

  the carriage allowing the latter to pass through the housing, or to slide it backwards until it contacts the lug, forces it to pivot upwards

  and enters the dwelling. Otherwise we can leave the

  riot on the rail so he's waiting for the arrival of

  the immediately following pin 70, in which case, when the

  When the car reaches the carriage, the spur pivots upwardly to let the carriage pass, the inertia of the carriage being large enough to cause the spigot to engage, instead of pushing it forward. The 45 degree equilibrium orientation of the ergot facilitates admission

  a trolley in the housing from a position

  killed initially in front of the ergot, as was

described above.

  Figure 10 shows the inclined element of

  extending 90 of the rail 12 leading to the secondary loop

  16 indicated by s and illustrates a role of limb pins

  70. The carriage 14 marked by o runs on the

  inclined rail 90 and rolled ahead of the associated pusher 15 spotted by o, under the action of gravity,

  to reach the ergot 70 marked by o, which er-

  got rotated slightly forward because of the inclination

  and the weight of the carriage 14-o to come into its carriage lock position. If not,

  without the 70-o lug, the trolley would travel all the way

  due ending to the back of the pusher 15 spotted

  by p. The carriage 14 indicated by q is represented as cir-

  at the beginning of the horizontal element 92 of the rail 12, but has previously circulated on the inclined element 90. A

  this previous moment, the carriage 14-q has advanced in

  originating from the rear of the limiting pin 70 indicated by q and when the carriage 14-q has reached the beginning of the horizontal element 92, as shown, its momentum has held it slightly in front of the pusher 15

  spotted by g. Then the carriage 14-q gradually retrograde-

  from ergot 70-q since its quantum

  moment of movement dissipates until the pusher

  -q have contacted him again, just when the

  evening identified by r caught up and contacted again the

  riot 14 spotted by r. In order to preserve the working space

  vail, the secondary loop 16 identified by s and the associated workstation 33 are located near the base

inclined rail 90.

  Assuming that the carriage 14-r is programmed to enter the 16-s loop soon after the pusher 15-r has passed the upstream end of

  rail 24 of the switching device 27, the

  The controller actuates the actuator 18 to return the rail member 24 to the interruption area of the secondary loop 16-s. The distance between the pusher 15-r and the pin 70 marked by r plus the distance, on

  which the pusher advances while the carriage is de-

  placed laterally, is less than the length of the

  rail 24, so that the carriage remains on this element.

  24 during switching and does not move forward

  beyond the rail element regardless of where the carriage is located within the housing 86 for the carriage. Note that if the limiting pin 70-r was not installed, the carriage 14-r could circulate advancing much further ahead of the pusher 15-r and advancing much more on the element of rail 24 before the arrival of the pusher 15-r, and unless it is stopped by

  grooves 71 on the rail element, it may

  completely removed from the operation of commu-

  tation. Likewise without the presence of the ergot 70-q, the chain

  riot 14-q could have circulated the entire distance extending to the rear of the pusher 15-r and, when the rail member 24 moves laterally to attempt to switch the carriage 14-r, the 14-q carriage could fall from the main rail to the interstice left free by the rail element 24, or get stuck

  or be switched by the switching device 27.

  Once the 14-r carriage has traveled the entire

  loop loop 28 of the secondary loop 16-s, it is driven upwards by the elevator 54, received by

  the rail element 24 and pushed back by the immediate pusher

  next element on the rail element 24 so as to be driven towards the main rail. Since the lug 70 associated with the pusher is located in front of the latter, when the rail member 24 comes into alignment with the main rail, the carriage is received within its respective housing 86 and can flow to front

  or else be shifted laterally towards the

  secondary 18 when ordered by the

nator.

  It is possible, although improbable, that, when

  that a carriage is contacted first by the pusher 15 at the upper part of the elevator, it is projected in

  before the pusher along the rail element 24 or advancing

  this under the action of gravity on the rail element 24,

  due to the presence of an inadvertent inclination.

  The grooves 21 present on the rail element 24 ar-

  stop the trolley before it falls out of the rail element. If the carriage 14 travels a distance of 20 centimeters in front of the pusher, when the rail member 24 is in alignment with the main rail, the carriage meets the lug 70 at an angle. However, due to the inclination of the rod 72 of the lug 70, the latter usually pivots upwards and releases

  possibly the passage of the trolley.

  It is also possible for the truck to stop

  when he meets the spigot, swinging slightly

  on the rail element 24, until the lug 70 advances

  this in front of the trolley, under the effect of the advance movement

  this of the chain 150, then enters the housing provided for the carriage. If the carriage continues to travel a distance of 20 centimeters in front of the pusher,

  will be in front of the limiting ergot, but will automatically

  annealing that the lug 70 exceeds the carriage.

  In the foregoing, an ergot of

  you last. For example, if desired, one can make

  the lug 70 in one piece with the chain so that it can not be detached from the chain. Likewise, if desired, the tip of the rod 72 of the lug 70 may be enlarged in the form of an inverted T in the case where the lug 70 is used with a carriage which has a

  vertical upper part narrowed in place of the head

  It is also possible to provide bevels in the lateral edges of the rod 72 of the lug 70 so that, in the case where a trolley

  meets the stem 72 by its cross, the bevels facilitates

  Attempt the upward pivoting of the lug 70 to allow the carriage to enter the housing 86. Similarly, the lug 70 may be used in a rail system having inclined elements which connect two stages. This is why the present invention has been

  described by way of illustration and not in a limited way

tative.

Automated transport system according to the   claim 2, further characterized in that said spur comprises an elongate shaft portion (72) and a portion of   head (76), that this head portion has a recess (78) serving   to accommodate, with possibility of rotation, said chain (150) and said stem portion extends from   of said chain within the path of said first first support.   - 5. Automated transport system according to the   claim 3, further characterized in that said spigot (70) pivots toward said associated pusher (15) to a loading position of the support, which is sufficiently raised relative to said guide means   (12) to allow a support (14) located initially   forward of said lug (70) on said guiding means   to move backwards, with respect to   bottom, below the latter, into a posi-   between this console and said associated pusher.   6. Automated transport system according to the   claim 3, further characterized in that the movement   pivoting of said lug forward is stopped at   level of a support blocking position in order to prevent   expensive that a support (14) located on said guide means   ge (12) between said pin and said associated pusher moves forward of said pin.   7. Automated transport system according to the   claim 3, further characterized in that said lug (70) has a center of gravity that forces it to assume an inclined position towards said associated pusher   (15) where the part of that chain on which   said pin is mounted, is horizontal and that said pin   subject to any force other than the force of tor.   8. Automated transport system according to the   claim 5, further characterized in that the movement   pivoting said pin (70) forward is stopped.   at a blocking position of a carriage, which   prevents a support (14) on said guide means from   bracket (12) between said lug and said associated pusher (15)   to move forward of said pin.   9. Automated transport system according to the   claim 6, further characterized in that said mold   pivoting movement of said lug (70) forward is ar-   stopped at said loading position of the chain.   riot, as a result of the abutment of said spur against said chain (150).
