Abstract

PURPOSE:To make a keyway of a beam ruffle part and a key member of a bearing shaft surely fittable with each other by driving a driving shaft as braking a driven shaft at the time of engagement between a beam and the bearing shaft by the key member. CONSTITUTION:A beam B is uplifted onto an axial extension of both driving and driven shafts 1 and 2, and thereby these shafts 1 and 2 are moved getting closer to the beam B. In this time, a fact that the driving shaft 1 and the driven shaft 2 both have come to contact with the end face of a beam ruffle B1 is detected by a sensor 3, the access movement of the driving shaft is stopped by the output signal, while a brake 6 installed in the driven shaft 2 and a motor 7 driving the driving shaft 1 both are operated. With this constitution, a relative rotational motion of the driving shaft 1 to the beam B and a relative motion of this beam B to the driven shaft 2 both are caused, whereby a key member of these driving and driven shafts 1 and 2 is fitted in the beam ruffle B1. When torque in the motor 7 or turning axis in the driven shaft 2 is reached to the set value, the motor 7 is stopped, and the brake 6 is released.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatically mounting a beam and an apparatus therefor, which can be used when automatically replacing a beam in a winder or a feeder.

[0002]

2. Description of the Related Art For many years, the textile industry has been actively promoting automation of each process in order to save labor.
An example thereof is an automatic beam exchange device attached to a winding machine or a sending machine for enabling continuous operation of a loom or a warper. With this automatic beam exchange, fully unattended continuous operation is possible day and night, and productivity can be greatly improved.

In this automatic attachment / detachment device, the lifting device holds the exchange beam at the beam flange portion or the beam ruffle portion, lifts it to a predetermined position on the machine base, and moves the beam back and forth in the beam axis direction. It automatically performs a series of operations of supporting by sandwiching it from the left and right by a shaft. In this automatic mounting, what is important is whether or not the beam is properly supported. This is because, of course, the left and right bearing shafts have a role of supporting the load of the beam, but at the same time have a role of surely transmitting the rotational power to the beam.

In consideration of the above, the present applicant first
By providing a taper at the tip of the bearing shaft and crimping this bearing shaft to the adapters attached to both ends of the beam with biasing springs, the same member supports the beam load and at the same time transmits rotational power. A device (Japanese Patent Application Laid-Open No. 2-154024) has been developed. However, in this device, the taper engagement portion between the adapter and the support shaft is easily affected by wear, dust, etc. In addition to the problem that power transmission was not reliable due to slippage, it was also necessary to manually install the adapter.

Therefore, in order to make the engagement between the beam and the support shaft more reliable, the applicant of the present invention provides a key member at the tip of the support shaft in place of the engagement by the taper so that both ends of the beam shaft can be secured. A device for transmitting rotational power by fitting into a key groove (Japanese Patent Application Laid-Open No. 3-186552, Japanese Patent Application No. 3-186552)
42167). This engagement by the key member makes it possible to reliably transmit power without any influence of dust etc. once the key member and the key groove are fitted together.

However, in this device utilizing the engagement by the key, the fitting of the key member and the key groove may not be successful depending on the type of beam to be replaced. When the supporting shaft moves toward both ends of the beam, when the key member comes into contact with a portion other than the key groove,
The key member urged to the beam side by the spring is
When the support shaft is retracted against the spring and the bearing shaft starts to rotate, this key member also rotates relative to the beam at the same time, and moves to the key groove portion while keeping contact with the beam. The key groove portion is configured to fit in the key groove. However, particularly when a relatively light beam is attached, when the key member is rotated, the beam may rotate together with the key member due to the frictional resistance of the contact portion between the tip of the key member and the beam. It was In this state, the key member and the key groove cannot be fitted to each other, and the next step is performed without fitting, which causes a problem.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the conventional beam automatic attachment / detachment device, and ensures that the key member and the key groove are fitted to each other. The present invention relates to an automatic beam mounting method and an apparatus therefor, in which a key member is not fitted properly and the next step is performed without being successful.

First, the structure of the apparatus of this embodiment will be described with reference to FIGS. In the figure, what is designated by the symbol F is a support shaft that is laterally mounted on a machine base such as a winder or a feeder. The support shafts F and F have a drive shaft 1 and a driven shaft 2 respectively. Supporters S ・ S
Is movably installed. This supporter S ・ S
The drive shaft 1 and the driven shaft 2 are driven by a power source (not shown).
And moves toward the beam B, and the drive shaft 1 and the driven shaft 2
Supports the beam B by sandwiching both ends of the beam B from the left and right. Further, the lifting device designated by the symbol L is
The beam B is to be lifted up or down to the axial extension line of the drive shaft 1 and the driven shaft 2, and is lowered from there, and is installed on the side surface of the supporter S as shown in FIG. 2, and is equipped with a fluid pressure cylinder L ₁ and a lifting arm L _2. It is composed of
It should be noted that the lifting devices L and L are shown only partially in FIG.

What is designated by the symbol P is a pulley fixed to the other end of the drive shaft 1, and the driving force of the motor 7 is transmitted to the drive shaft 1 by the pulley P and the belt Q. The motor 7 is controlled to operate at a predetermined speed by the speed setting device D and the control device C. Further, the control device C determines that the torque current value of the motor 7 detected by the detector 8 is the torque setting device 9 in advance. When the set current value set in step 1 is reached, a stop signal is sent to the motor 7. Further, what is indicated by reference numeral 6 is a brake installed at the other end of the driven shaft 2 and brakes the rotation of the driven shaft 2.

Next, the structures of the drive shaft 1 and the driven shaft 2 will be described in detail with reference to FIGS. Reference numeral 3 in the figure
Is a contact sensor that detects that the tip surfaces of the drive shaft 1 and the driven shaft 2 have come into contact with both ends of the beam ruffle B ₁ and outputs a detection signal. 1 and the driven shaft 2 are provided with touch rods 3a and 3a, which are respectively provided to project forward and backward while being urged toward the beam side by a spring 3b, and touch plates 3c and 3c fixed to the touch rod 3a. Through the interposition, it is detected that the drive shaft 1 and the driven shaft 2 contact the beam raffles B _{1 at} both ends of the beam.

Further, what is indicated by reference numeral 5 is a key member having a shape which can be fitted into key holes formed in both end faces of the beam ruffle B ₁ , respectively. The key member 5 is driven by the drive shaft 1 and the driven member. A spring 5a is provided at the tip of the shaft 2 so as to project forward and backward while being urged toward the beam side. As described above, when the drive shaft 1 and the driven shaft 2 approach and contact the beam B by the movement of the supporters S, S, the key members 5, 5
Even if the tip of the key comes into contact with a portion other than the key hole, the key member 5
The 5 is designed to withdraw against the biasing force of the springs 5a and 5a.

Next, the operation sequence of the apparatus of this embodiment will be described with reference to FIG. With the start of the automatic beam mounting, the lifting arm L ₂ holding the beam B is raised, and the beam B is positioned on the extension line of the drive shaft 1 and the driven shaft 2. Then, the supporters S and S move toward the beam B until the tips of the drive shaft 1 and the driven shaft 2 come into contact with the end face of the beam ruffle B ₁ . To stop the movement of the supporters S and S, touch the rod 3 that comes into contact with the end face of the beam ruffle B _1.
This is performed by the detection signal from the sensor 3.3 output when the touch plate 3c fixed to a contacts the sensor 3.3.

The detection signals from the sensors 3 and 3 further actuate the brake 6 provided on the driven shaft 2 and the motor 7 that drives the drive shaft 1. at this point,
Even if the key member 5 on the drive shaft 1 side is not fitted in the key hole of the beam ruffle B ₁ , the key member 5 together with the drive shaft 1
Since the rotary motion is relative to the beam B, the drive shaft 1
The key member 5 on the side moves to the key hole portion on the end face of the beam ruffle B ₁ and is fitted at the key hole portion. Then, this time, the beam B fitted with the key member rotates together with the drive shaft 1 relative to the driven shaft 2 braked by the brake 6. Due to this rotational movement, the key hole of the beam raffle B ₁ moves toward the key member 5 on the driven shaft 2 side, and eventually the key member 5 is fitted. Thus
The drive shaft 1, the beam B, and the driven shaft 2 are reliably connected.

By the way, although the key member 5 on the drive shaft 1 side is not fitted in the key hole of the beam ruffle B ₁ ,
For example, due to frictional resistance between the retracted tip of the key member 5 and the end face of the beam ruffle B ₁ , the beam B may also rotate as the drive shaft 1 rotates. Since the key member 5 on the second side is fitted into the key member 5 first, a relative rotational movement of the key member 5 on the drive shaft 1 side with respect to the beam B is eventually generated.
The reliability of the connection between the driven shaft 2 and the driven shaft 2 is not impaired at all.

As described above, when the drive shaft 1, the beam B and the driven shaft 2 are connected, the driven shaft 2 is braked by the brake 6 at that moment, so the motor driving the drive shaft 1 is driven. The load of No. 7 increases, and the torque current value of the motor 7 increases. This current value is detected and the detected value is sent to the control device C. The control device C compares the detected current value with the set current value set in the torque setting device 9 in advance, and when the detected current value reaches the set current value, sends a stop signal to the motor 7 so that the motor 7 Stop. And the driven shaft 2
The brake 6 that has been braking is released, the lifting arm L ₂ is lowered, and the winder and the delivery machine are ready to be activated.

The embodiment of the present invention is configured as described above, but the present invention is not limited to this embodiment, and various modifications can be made within the scope of the claims. , For example, the confirmation of the connection between the drive shaft 1, the beam B, and the driven shaft 2 is detected not by the change of the motor current but by the change of the motor rotational speed due to the increase of the drive load by using the pulse encoder, or the speed control It is also possible to use the speed deviation from the speed setter D when performing.

When the drive shaft 1, the beam B and the driven shaft 2 are connected, the braking force of the brake 6 is set so that the driven shaft 2 is rotated by the driving force of the motor 7, and further on the circumference of the driven shaft. The protrusion T is provided, and the switch U that turns on when the protrusion T that rotates with the driven shaft 2 comes into contact is used as a detector, or the encoder that detects a change in rotation of the driven shaft 2 is used as a detector. Alternatively, the connection may be confirmed (see FIG. 6).

[0021]

As described above with reference to the embodiments, according to the method of the present invention, when the beam and the bearing shaft are engaged by the key member effective for transmitting the rotational power, the driven shaft is driven while being braked. By driving the shaft, the relative rotational movement is positively caused with respect to the beam, so that the key member can be reliably fitted regardless of the type of the beam.

Further, the key operation is confirmed by detecting either one of the change of the motor torque due to the increase of the driving load and the rotation of the driven shaft, and then the next operation is started. Therefore, the safety of the work is significantly improved.
