Detailed Description
The floating accumulator for cables according to the present invention will be described in detail with reference to the accompanying drawings in conjunction with the embodiments.
The embodiments described herein are only a portion of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, shall fall within the scope of protection of the present invention. Features in the embodiments in the present application may be combined with each other without conflict. The terms "first," "second," and the like in the description and in the claims, and the drawings of the present invention are used for distinguishing between similar elements and not necessarily for describing a particular order, such terms being used interchangeably where appropriate.
Referring to fig. 1 and 2, a floating accumulator 100 of an embodiment of the present invention comprises a vertical stand 1 including a main body 11 and an elongated extension 12; the extension may be an elongated rod or beam. A cylinder assembly 3 is fitted on the main body of the vertical stand 1, the cylinder assembly 3 including a cylinder block 31 fixed to the main body 11 of the vertical stand, and a cylinder rod 32 movable from the cylinder block 31, the cylinder rod being oriented to be extendable in the direction of the extension 12 and retractable in the direction of the main body 11. On the cylinder rod 32, the moving bracket assembly 2 is preferably fixed at an end portion, so that the cylinder rod can drive the moving bracket assembly 2 to make a linear motion together, in order to make the motion of the moving bracket 2 more stable, the moving bracket assembly 2 can be made to be matched with the guide rail 5, for example, one surface of the moving bracket assembly is attached to the surface of the guide rail 5, or the moving bracket assembly has a limiting portion and is matched with the side surface of the guide rail, so that the moving bracket assembly 2 can be smoothly translated along the guide rail 5. The guide rail 5 may extend in the longitudinal direction of the extension 12 and be fixed to the extension 12. The guide rail may be plate-shaped. Preferably, the guide rail extends the entire length of the extension.
The moving carriage assembly 2 is coupled to the moving swivel wheel assembly 4 such that the moving swivel wheel assembly 4 moves in translation with the moving carriage assembly 2 in response to movement of the cylinder rod. The mobile swivel wheel assembly 4 may have a swivel wheel base fixed to the mobile carriage assembly 2; and one or more wheels that pivot relative to the wheel base; the wheel may have a guide channel within which the cable is supported.
The tightness of the cables on the production line can be adjusted by actuating the pneumatic assembly so that the cylinder rod drives the mobile carriage 2 in translation, and therefore the mobile swivel wheel assembly 4 thereon in translation, to approach or to move away from the stationary swivel wheel assembly 9.
A tension sensor 6A may be provided on one or both of the stationary turret wheel assembly 9 and the moving turret wheel assembly 4 to detect tension in the cable on the production line in real time. The tension sensor 6A may be, for example, model M1391-C manufactured by Tensomesmestechnik GmbH. The tension sensor 6A is electrically connected, wired or wirelessly, to a local control system 8 for transmitting the electrical signals generated by the tension sensor 6A to the control system 8 in real time, the control system 8 being for example any well known processing system, such as a control unit having a processor and memory architecture. The control system 8 is also electrically connected to the pneumatic control element 7 of the cylinder assembly 3 to transmit control signals to the pneumatic control element 7, for example control signals controlling the action of the extension or retraction of the cylinder rod.
The control mechanism of the pneumatic control element 7 by the control system 8 to achieve translation of the moving return roller assembly 4 within the stroke L shown in fig. 2 is explained below by way of example with the tension sensor 6A being provided on the stationary return roller assembly 9.
The stationary anti-return pulley assembly 9 is first moved to the position of the return pulley assembly 4 preset with a preset tension.
As the static anti-return pulley assembly 9 moves the return pulley assembly 4 to transmit the cable, the tension sensor 6A transmits a first detection signal of the tension of the cable to a control system in real time;
after receiving the first detection signal from the tension sensor 6A, the control system determines the relationship between the signal and a given threshold value representing the desired tension, and if the relationship is greater than the given threshold value, sends a control signal to the pneumatic control element 7 to make the cylinder rod of the air cylinder act to make the moving bracket 2 with the moving return pulley assembly 4 move towards the body 11 of the upright bracket 1 to reduce the distance between the moving return pulley assembly 9 and the moving return pulley assembly 4, so as to reduce the tension of the cable by the moving return pulley assembly 9 and the return pulley assembly 4 until receiving the subsequent first detection signal equal to the given threshold value; conversely, if less than a given threshold, a control signal is sent to the pneumatic control element 7 so that the action of the cylinder rod of the cylinder causes the movement of the mobile carriage 2 with the mobile swivel assembly 4 in the direction of the extension 12 of the upright 1 to increase the distance between the mobile swivel assembly 4 and the mobile swivel assembly 9, thus increasing the tension of the cable by the mobile swivel assembly 9 moving the swivel assembly 4 until the subsequent first detection signal is received equal to the given threshold. It should be understood that the threshold may be a range of thresholds, and correspondingly, the determination is made as a maximum value greater than the range of thresholds and a minimum value less than the range of thresholds.
Because the wire storage device is started and stopped at any time according to the detection condition of the tension sensor arranged on the fixed wheel, the wire storage device is used for ensuring that the cable is in a preset certain tension range to ensure the quality of the cable,
referring to fig. 1 and 2, the floating wire storage may further include a path position sensor 6B, and the path position sensor 6B is electrically connected to the control system 8 and may be disposed on the extension or the guide rail 5 to provide a second detection signal to the control system 8 whether the moving rack 2 exceeds a preset position.
In some embodiments, the second detection signal may be used as a basis for the cylinder rod, such as a basis for determining a position where the cylinder rod has been extended or retracted, and the control system 8 may be configured to determine that the cylinder rod has been extended or retracted to a limit position according to the second detection signal, for example, a preset limit position value is exceeded, but the tension of the cable is not within a preset threshold value, that is, when the first detection signal fed back by the tension sensor 6A indicates that the tension of the cable is not equal to the preset threshold value or within the preset threshold value, the control system 8 sends an alarm signal corresponding to the situation to an external general control system (not shown), and the general control system sends an instruction according to the alarm signal to actuate an external take-up and pay-off reel (not shown) until the tension of the cable indicated by the first detection signal is equal to the preset threshold value or within the preset threshold value or vice versa And when the tension exceeds the preset threshold or the preset threshold range, the tension of the production line is ensured to be within a set range, and the production requirement is met.
And simultaneously sending the alarm signal to the external master control system, sending a signal to the pneumatic control element 7 to stop the movement of the cylinder rod, so as to help accurately determine the current movement position of the cylinder rod and more accurately control the action amplitude of the take-up and pay-off reel.
When the action of the take-up and pay-off reel enables the tension of the cable indicated by the first detection signal to reversely exceed the preset threshold value or the preset threshold value range, the step of adjusting the pneumatic control element 7 according to the first detection signal is continuously executed, so that the tension of the cable is equal to the preset threshold value or within the preset threshold value range.
The amount of the accumulated wire can also be calculated by the second detection signal of the path position sensor 6B.
Referring to fig. 1 and 2, the floating storage may further include a guard rail 10, which may have a door lock 103 thereon. The guard rail 10 may have an opening therein to allow at least a portion of the extension 12 to extend upwardly out of the guard rail. As a part of the protection system, the protection system further comprises an emergency stop switch 101 and a start button 102 which are both arranged on the guard rail; the emergency stop switch and the start button are electrically connected with the control system 8 to realize emergency stop and start and stop of the wire storage device.
