Definitions

  • This invention pertains to the .art of methods and apparatuses for adjusting the length of a conveyor system to compensate for changes in the length of a strip material caused by intermittent feeding or by changes in speed of feeding, and more specifically to methods and apparatuses for supporting the strip material in a generally horizontal attitude during the length adjustment.
  • Background Art In the past, vertical festoons were used to adjust the length of a conveyor system to compensate for intermittent feeding of strip material to meet variable production requirements. However, when vertical festoons were used, the strip material was not supported and was stretched by its own weight. This stretching of the strip material was not desirable when assembling a product such as a tire.
  • One such conveyor of strip material is found in U.S. Patent No. 4,892,609 to Nakanome et al., which discloses an automatic material feeder in tire forming machines. The machine has a traditional vertical festoon to support the buildup of tire building materials.
  • the present invention contemplates a new and improved adjustment for a conveyor system which is simple in design, effective in use, and overcomes the foregoing difficulties and others while providing better and more advantageous overall results.
  • a new and improved adjustable substantially horizontal conveyor which compensates for the changes in length of the strip material being conveyed as a result of intermittent feeding without altering the weight or shape of the strip material.
  • a conveyor assembly for conveying and storing an associated strip material in a conveyor system.
  • the conveyor assembly includes an upper conveyor for receiving and conveying the associated strip material.
  • the upper conveyor has a first conveyor belt and a first driving means for driving the first conveyor belt.
  • the upper conveyor is substantially stationary.
  • a center conveyor receives the associated strip material from the upper conveyor, and has a second conveyor belt and a second driving means for driving the second conveyor belt.
  • the center conveyor is movable along a substantially horizontal path and has length adjusting means for moving the center conveyor along the path.
  • a lower conveyor is provided for receiving the associated strip material from the center conveyor, and has a third conveyor belt with a third driving means for driving the third conveyor belt.
  • the lower conveyor is substantially stationary.
  • a length adjusting conveyor for storing a variable length of strip material in a conveyor system including supply means for supplying the associated strip material to the length adjusting conveyor with the length adjusting conveyor having a conveyor belt and driving means for driving the conveyor belt, the length adjusting conveyor being movable along a substantially horizontal path; power means for moving the length adjusting conveyor along the path; and, take away means for receiving the associated strip material from the length adjusting conveyor.
  • a method of conveying an associated strip material along a conveyor assembly wherein the conveyor assembly includes an upper conveyor having a first conveyor belt and a first driving means, a center length adjusting conveyor having a second conveyor belt and second driving means, and a lower conveyor having a third conveyor belt and third driving means, the method including the steps of: conveying the associated strip material along the upper conveyor in a first direction with the first driving means; transferring the associated strip material to the center length adjusting conveyor; moving the center length adjusting conveyor along a substantially horizontal path to adjust the length of the conveyor .assembly in response to changes in length of the associated strip material; conveying the .associated strip material along the center length adjusting conveyor in a second direction opposite the first direction with the second driving means; transferring the associated strip material to the lower conveyor; and, conveying the associated strip material along the lower conveyor in the first direction with the third driving means.
  • a method of adjusting the length of a conveyor system to compensate for changes in the length of an associated strip in a conveyor system the conveyor system having a length adjusting conveyor with a conveyor belt and driving means, supply means, and take away means
  • the method including the steps of: supplying the associated strip material to the length adjusting conveyor with the supply means; moving the length adjusting conveyor in a substantially horizontal direction in response to changes in length of the associated strip material in the conveyor system; conveying the associated strip material along at least a portion of the length adjusting conveyor with the driving means; and, transferring the associated strip material to the take away means.
  • One advantage of the present invention is that the conveyor system may adjust for variable lengths of the strip material in the system caused by different supply and take away speeds including stoppage at the takeaway position.
  • Another advantage of the present invention is that the conveyor system adjusts for changes in the length of the strip material in the system without changing the stresses on the strip material.
  • Figure 1 is a schematic side elevation of a conveyor assembly embodying the invention showing the center conveyor in the retracted position;
  • Figure 2 is a schematic side elevation of the conveyor assembly of Figure 1 with the center conveyor in the extended position;
  • Figure 3 is an enlarged fragmentary view of part of the center conveyor showing a preferred embodiment of the present invention utilizing a proximity switch; and, Figure 4 is a schematic side elevation of the conveyor assembly of Figure 1 with a proximity switch at the end of the center conveyor and the upper conveyor.
  • FIG. 1 shows a schematic view of a conveyor assembly 10 embodying the system of the invention.
  • the conveyor assembly 10 preferably has an upper conveyor 16, a center conveyor 22, and a lower conveyor 28.
  • a strip material 34 of rubber or other deformable material is conveyed by the conveyor assembly 10 from a supply position 40, such as from an extruder, along a path 44 to a take away position 46, for feeding the strip material to apparatus such as a strip applicator.
  • the strip material 34 is conveyed from the supply position 40 over the upper conveyor 16 in the direction of arrow A by a conveyor belt 52 driven by a first servomotor 58.
  • the strip material 34 is then transferred to the center conveyor 22, preferably by allowing the strip material to fall over an end 60 of the upper conveyor 16 onto the center conveyor where the strip material is moved in a reverse direction as shown by arrow B.
  • the strip material 34 is turned over and is conveyed on the center conveyor 22 on a conveyor belt 64 driven by a second servomotor 70. At a leading end 72 of the center conveyor 22, the strip material 34 is then transferred to the lower conveyor 28, preferably by allowing the strip material to fall over the end of the center conveyor onto the lower conveyor where the strip material again reverses direction in the direction of arrow A and is turned over to the same position as it was on, the upper conveyor 16 so that it is right side up.
  • the lower conveyor 28 conveys the strip material 34 in the direction of arrow A along a conveyor belt 76 driven by a third servomotor 82 to the take away position 46.
  • the upper conveyor 16 conveys the strip material 34 at an upper conveyor speed SI that equals the speed at which strip material is provided at the supply position 40.
  • the lower conveyor 28 conveys strip material 34 at a lower conveyor speed S2 that equals the speed at which the strip material is taken away at the take away position 46.
  • speed SI equals speed S2
  • speed S3 the center conveyor 22 conveys strip material 34 at a speed S3 that is equal to speed
  • a computer 94 is used to control the servomotor 70 that drives the center conveyor belt 64.
  • the center conveyor 22 may be supported on a frame which is mounted on a servomechanism 100 such as a belt driven liner actuator having a servo motor to move the frame and supported center conveyor back and forth substantially horizontally, in the directions of arrows A and B.
  • computer 94 preferably directs servomotor 70 to rotate the center conveyor belt 64 at a speed S3 that is equal to the average of speeds SI and S2 or one half of the sum of speeds SI and S2.
  • Computer 94 is also connected to the servomechanism 100 which moves the center conveyor 22 at a speed S4 that is equal to one half of the difference between speed S3 and speed S2. If speed S3 is greater than speed S2, the center conveyor 22 is moved in the direction of arrow B. If speed S2 is greater than the speed S3, then the center conveyor 22 is moved in the direction of arrow A.
  • the speed S4 at which the center conveyor 22 is moved is predetermined for the condition where S2 is zero between feeding of the strip material 34 and where S2 is greater than SI, during the feeding of the strip material. Additionally, an optical sensor 88 is placed near the end 72 of the center conveyor 22 to detect whether a loop 90, shown in dotted lines, is formed by decreased tension in the strip material 34 due to the speed S2 of the lower conveyor 28 being less than the speed SI of the upper conveyor, and when the computer 94 has not made a correction for the decreased tension in the strip material.
  • the computer 94 receives a signal from the optical sensor 88 and in response causes the servomechanism 100 to move the center conveyor 22 for a predetermined time in direction B to adjust the length of the strip material 34 by picking up the slack in. the strip material.
  • Figure 2 shows a schematic view of the conveyor assembly 10 with the center conveyor 22 moved to the right and acting as a length adjusting conveyor by increasing the length of the path 44 to accommodate the increased length of the strip material 34 in the system as the strip material is moved along the conveyor assembly 10.
  • the servomechanism 100 has moved the center conveyor 22 in the direction of arrow B at the direction of the computer 94 or after the sensor 88 detected a loop 90. This movement has increased the length of the path 44 to compensate for the increased length of the strip material 34 in the system and allows the conveyor assembly 10 to support the strip material without increasing the tension in the strip material. This is particularly important for materials such as extruded rubber that are susceptible to deformation under tension.
  • the computer 94 will once again convey signals to the servomechanism 100 to move the center conveyor in the direction of arrow B. This process of moving the center conveyor 22 back and forth keeps the conveyor assembly 10 in an equilibrium position and the tension on the strip material 34 substantially constan t .
  • a proximity switch 106 is disposed at the end 72 of the center conveyor 22 to detect the loop in the strip material 34.
  • the proximity switch 106 includes a roller 108 attached to a metal contact 112.
  • the roller 108 is guided by slides 114,116 located at the sides 120 , 122 of the center conveyor 22.
  • the roller 108 is pulled in direction A by the tension of the strip material 34, and in direction B by springs 132,134 that are connected to the roller.
  • the metal contact 112 moves back and forth between two contacts 124,126 to form a switch.
  • speed SI is equal to speed S2
  • the proximity switch 106 is held in an equilibrium position, and the metal contact is suspended between the two contacts 124,126.
  • a loop 90 forms around the proximity switch 106, and the tension on the roller 108 is reduced, thereby allowing springs 132, 134 to pull the roller and the metal contac t 112 into engagement with contact 124, and thereby closing a circuit that includes the power supply 118 and detection apparatus 140.
  • the detection apparatus 140 then causes activation of the servomechanism 100 (see Figure 2) to move the center conveyor 22 at a speed S4 equal to one half the difference of speeds S3 and S2 to adjust the path 44 of the strip material 34 by increasing the length of the path of the strip material. If speed S2 is greater than speed S 1 , then a greater amount of tension is placed on the roller 108.
  • the tension on the roller 108 overcomes the pull of springs 132,134 and the metal contact 112 comes into engagement with contact 126, thereby closing a circuit that includes the power supply 118 and detection apparatus 142.
  • the detection apparatus 142 then causes activation of the servomechanism 100 (see Figure 2) to move the center conveyor 22 at a speed S4 equal to one half the difference between speeds S3 and S2 in direction A as shown in Figure 2 to release strip material 34 taken up by prior movement of the center conveyor and thereby decrease the length of the path 44 of the strip material.
  • a conveyor assembly 10 is shown with the proximity switch 106 at the end 72 of the center conveyor 22. Additionally, a second proximity switch 106' is located at the end 60 of the upper conveyor 16. The second proximity switch 106' further enables the conveyor assembly 10 to detect changes in tension in the strip material 34 by detecting a loop 152 that forms around the end 60 of the upper conveyor 16.
  • the second proximity switch 106' has a roller 108', contacts 124' and 126' and is also connected to the servomechanism 100 that controls the speed S4 of the center conveyor 22.
  • the conveyor assembly 10 may employ more than one center conveyor 22 to increase the capacity of the conveyor assembly to accommodate changes in the length of the strip material 34 caused by intermittent feeding of strip material at the takeaway position 46.
  • Each center conveyor 22 may be equipped with either an optical sensor 88 or proximity switch 106 to detect a loop 90 in the strip material 34 at the end of the center conveyor.
  • the strip material 34 may also be fed through the conveyor assembly 10 to a supply position 40 along the path 44 in the direction opposite that described heretofore.
  • a computer may be connected to the servomechanisms 100 of the center conveyors 22 for controlling their movement during intermittent operation of the lower conveyor 28. While certain representative embodiments and details have been shown for the purpose of illustrating the invention, it will be apparent to those skilled in the art that various changes and modifications may be made therein without departing from the scope of the invention.

Abstract

Ensemble bande transporteuse et procédé permettant de transporter et de stocker un matériau en bande dans un système de bande transporteuse soumis à des changements de longueur du matériau en bande dus à un fonctionnement intermittent. Ladite bande transporteuse comporte une bande transporteuse supérieure (16), une bande transporteuse centrale pratiquement horizontale réglable (22) destinée à recevoir le matériau en bande (34) depuis la bande transporteuse supérieure et une bande transporteuse inférieure (28) destinée à recevoir le matériau en bande associé depuis la bande transporteuse centrale. Un ordinateur (94) commande le mouvement et la rotation de la bande transporteuse centrale et un appareil de détection de boucles situé sur la bande transporteuse centrale peut également détecter une boucle (90) dans le matériau en bande porté par la bande transporteuse centrale et détecter ainsi des modifications de la longueur du matériau en bande qui ne sont pas prédéterminées par l'ordinateur. Un servomécanisme (100) actionné par des signaux produits par l'ordinateur ou l'appareil de détection de boucles déplace la bande transporteuse centrale dans une direction pratiquement horizontale.
