Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bobbin transfer device, and particularly to a bobbin transfer device for transferring a real bobbin from a spinning machine onto a conveyor for transferring to a winder.

[Prior Art] In a winding process for rewinding yarn on a bobbin in a mechanized yarn twisting factory, it is necessary to sequentially supply the actual bobbins produced by a spinning machine to a winder.

As shown in FIGS. 10 and 11, normally in the production line J3 for this winding process, a spinning machine S and a winder W are installed in series and close to each other.

The real bobbin B, on which the spun yarn produced by the spinning machine S is wound, is fixed onto a transport band, which is two transport paths a, formed along the longitudinal direction of the line by a known simultaneous doffing device. They are all vertically supported by the beg b and sent to the conveyance end P facing the winder W, where they are put on standby. On the other hand, the winder W is provided with a closed-loop transfer conveyor C, which carries out empty bobbins d or remaining yarn bobbins after being wound into packages, and supplies actual bobbins B to each winding unit e. It is supposed to be done. And spinning i
An empty tray is placed on standby at a predetermined position Q,
Real bobbin B is now received.

Conventionally, a device f for transferring the real bobbin B from the real bobbin standby position P to the empty tray standby position Q is provided between the spinning machine S and the winder W, and is located at the inclined end of the conveyance path a. It was configured to have a connecting guide chute (not shown). In other words, the actual bobbin B that is being conveyed in an upright position is tilted down by φλ, and is made to fall along the chute using its own weight, and is transferred to the empty tray 1 to the lay standby position Q, where it is inserted into the empty tray. It had become.

[Problem to be solved by the invention 1 However, in the above conventional device f, the actual bobbin B
Since the thread slides along the guide surface of the chute, the surface of the thread layer that comes into contact with the thread layer may be abraded, damaging the thread layer, or the thread end may get caught on another member, causing the thread end to be pulled out. was there.

In addition, by slanting the conveyance path a, by loading the pretext bobbin B into the shoe 1 after receiving it, a space for the bobbin transfer section, that is, an inclination of the conveyor or an inclination of the guide chute, is required. In the illustrated system in which the spinning machine S and the winder W are directly connected, there is a problem in that the space required for transfer becomes large.

Therefore, the present invention was devised to provide a bobbin transfer device that does not require the use of actual bobbins and does not require a large space.

Means for Solving Problem 1 The present invention provides a system in which a real bobbin, which is vertically supported and transferred from a spinning machine on a conveyance path and is on standby, is vertically erected on a tray provided on a transfer conveyor of a winder.

A barrel roller 43 is rotatably provided and engages with the first cam 14. The arm 41 on the substantially opposite side extends above J: of the inner frame 30 and is pivotally supported by one end of a crank arm 44, which is a crank mechanism 37, and is provided substantially horizontally from the end side that is the point of action. There is. The remaining arm 42 is connected to a spring 46 by a rod 45 provided at the bottom of the housing 1.
The first lever 36 is always urged downward so that the first lever 36 is engaged with the first cam 14.

The crank mechanism 37 includes two crank arms 44, a fan-shaped plate 47 connected to the other end of the crank arm 44, and a claw member 48 supported by the fan-shaped plate 47 via a vertical shaft member 52.
and a disc 49 which is fixed to the vertical shaft 2 and has a partial notch for engaging the pawl member 48. That is, the backward movement of the crank arm 44 in the longitudinal direction is converted into rotation of the disk 49.

Two discs 49 are connected in a concentric manner and are spaced apart from each other by a predetermined distance. Of these, the disk 49 shown in FIG. 5 is arranged clockwise from Q to P in the figure.
It is rotated by a predetermined angle up to l. The rotation in the opposite direction (from Q to P2) is similarly rotated by the other crank arm 44 in which four discs on the side not shown are arranged side by side. In this embodiment, the predetermined angle is approximately 116 degrees, and is determined in accordance with the standards of the spinning machine S and winder W to which the angle is applied, and the length of the swing arm 4.

A switching means is provided for appropriately engaging the claw members 48 with these four discs.

The switching means includes a switching drive section 70 supported by an inner frame, and a switching lever 71 that is appropriately swung by the switching drive section 70, and these are connected by a crank rod 72.

The lζ pins 54 protrude from the
Both ends of the claw member 48 are engaged with the four discs, thereby urging the claw member 48 to always be in an engaged position with the four discs. Therefore, the switching lever 71 is moved by the disengagement slide 1f against this biasing force.

On the other hand, a rotating body 5 for returning the vertical sleeve 2 rotated by the crank mechanism 37 to its original position (the position shown in FIG. 5)
7 is provided above the elevating body 3.

As shown in FIGS. 6 and 7, the rotating body 57 is divided into upper and lower parts, each of which is rotatably provided around the vertical shaft 2. As shown in FIGS. These rotating bodies 57 are formed with flange portions 58 that protrude outward in the radial direction, and are connected to each other by five springs provided between the flange portions 58.

Further, a flange portion 58 is provided on the frame body 30 on the radially outer side of the rotating body 57.
A stopper 80 is provided at a position where the distal end abuts to sandwich it in the horizontal direction. That is, either one of the flange portions 5
8 is engaged with the bolt member 56 and moved around the axis, the other comes into contact with the stopper 80 and urges it to the opposite side. In other words, the vertical shaft 2 rotated by the crank mechanism 37 is rotated in the opposite direction.

The elevating drive means 6 includes a second cam 15 formed in a flllffl shape and fixed to the main drive shaft 13 at approximately the center, a second lever 61 engaged with the second cam 15, and a second lever 61 that is engaged with the second cam 15. 6
1 and a link mechanism 62 that connects the elevating body 3.

The second cam 15 is attached in an appropriate direction in relation to the shape of the first cam 14, that is, the pivoting operation.

As shown in FIG. 4, the second lever 61 is bent in an oval shape, the pivot shaft 63 serving as a fulcrum is located at one end thereof, and the roller 64 serving as a point of effort is bent. It is located in the department. The other end, which is the point of action, is rotatably supported by one end of a rod 65, which is a link mechanism 62, as shown in FIGS. 6 and 7. The other end of the rod 65 is connected to the lower ring body 34 of the elevating body 3, and the swinging of the second lever 61 is controlled by the movement along the axial direction of the vertical shaft 2.
In other words, it is converted into an upper bound and a lower bound. Further, a heavy cone 66 is provided at the connecting portion to apply downward force. That is, the second lever 61 is always engaged with the second cam 15.

Next, the operation of this embodiment will be explained.

When the motor 11 serving as the drive source is rotated, the main drive shaft 13, cams 14, 15, lever 36 . ．． The driving force is sequentially transmitted to 61. The first lever 36 is appropriately swung by the first cam 14 and rotates the vertical shaft 2 through a predetermined angle range via a crank mechanism 37. At this time, the rod 44 is moved to the right in FIG. 5, and the fan-shaped plate 47 is rotated clockwise.

The claw member 48 transmits this rotation to the disc 49.

The elevating body 3 transmits the rotation of the vertical shaft 2 to the vertical arm 31 and the swing arm 4 to make a predetermined swing. after that,
As the rod 44 moves to the left, the spring 59 of the rotating body 57 rotates the vertical shaft 2 in the opposite direction, returning the swing arm 4 to its original position.

Simultaneously with the turning, the second lever 61 is appropriately swung by the second cam 15 to move the elevating body 3 up and down along the axial direction of the vertical shaft 2 via the link mechanism 62. That is, the swing arm 4 is raised and lowered as appropriate.

As shown in FIGS. 8 and 9, these rotations and elevations proceed as follows in terms of the position of the gripping means 5.

■ Grip the head 18 of the real bobbin B at the real bobbin standby position P.

■ Handle the actual bobbin B from the tray while holding it, rise and turn toward the winder W side.

■ It is located above the tray at the empty bobbin standby position Q.

■ Go down, seat the real bobbin B on the tray, and release the grip.

■ It rises and separates from the actual bobbin.

■ Descend and turn to the spinning machine S side.

■ Located above the actual bobbin standby position P.

■ Go down and grasp the head 18 of the real bobbin B.

The gripping means 5 is driven in the steps (■) and (2) above. In (2), as the elevating body 3 descends, the gripping portion 17
The inner side of the bobbin B comes into contact with the head 18 of the real bobbin B and is pushed up, and the air passage 21 is communicated with the air supply passage 22. The air chamber 19 is supplied with compressed air and expands, thereby substantially reducing the diameter of the gripping portion 17 and gripping the real bobbin B. In the above case (2), the roller 2 of the lever member 24 is
3 is pushed up by the contact portion 25, and moves the grip portion 17 downward. This causes the compressed air in the air chamber 19 to flow out, substantially expanding the diameter of the gripping portion 17 and opening the actual bobbin B. In addition, in this (■) or a stage other than (■), the air passage 21 is blocked by the spring 27 that engages with the lever member 24, the state of the air v19 is maintained, and gripping and gripping release are intermittent.

In this way, since the head 18 is gripped and transferred without contacting the yarn layer of the real bobbin B, the yarn layer is not damaged. Also, along the erected vertical axis 2,
Since the device can be raised and lowered by turning, the space required for the device can be reduced.

Further, since the C drive is performed by one driving source via the cams 14 and 15, it is highly versatile.

This means, for example, that the rotational speed of the driving shaft 13 can be changed as appropriate.
20, which corresponds to high-speed processing of the winder W.
It becomes possible to transfer at a high speed of about 100 books per minute. However, in this case,
The shape of the cams 14 and 15 needs to be shaped into a cycloid curve or the like that allows smooth transmission of driving force.

Generally speaking, in this embodiment, since a switching means is provided, it is possible to transfer the spinning machine S in accordance with the production process. For example, if the conveyance path that conveys the fruit bogon B switches to another conveyance path at 500 wood 1d, the original position Q
The switching lever 71 may be swung so as to switch from the pivot position P1 to the opposite side P2. In this case, the switching drive section 70 may be formed in synchronization with the spinning machine S.

J: Since the return P-40 of the swing is performed by the biasing force of the spring 59, consideration has been given to the safety issue that may arise due to the swing arm 4 swinging above the conveyance path. For example, even if a worker or the like comes into contact with the swing arm 4 when returning, there will be no harmful impact. Further, the load on the swing driving means 7 at this time is also reduced.

Although this embodiment is illustrated as a case where there is a step difference between the winder W side and the spinning frame S side, the present invention can also be applied to a case where the heights are the same. In this case, cam 14.15
This can be handled by changing the shape of the .

[Effects of the Invention] To summarize, according to the present invention, the following excellent effects are achieved.

(1) Since the bobbin is transferred by a gripping means that grips the head of the bobbin, accidents such as damage to the yarn layer and pulling out of the yarn end can be prevented.

(2) Since the gripping means is moved up and down and rotated along the vertical axis, a guide chute and an inclined conveyance path are no longer required, which reduces the space for transfer, and improves the machine layout that makes up the winding process. The degree of freedom in the above design increases.
