Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Field of Industrial Application) This invention relates to a full bobbin insertion device for a spinning machine.

(Prior Art) In recent years, various operations have been automated in textile factories for the purpose of saving labor and improving productivity. One of these devices is a full bobbin insertion device that inserts a full bobbin into a peg, for example, on October 27, 1975.
As shown in FIG. 8, Japanese Patent Application Laid-open No. 50-135356 discloses that each take-up weight of a winder is provided with a full bobbin storage magazine, and each time a full bobbin of the take-up weight is consumed, one magazine is loaded. As a device that rotates in pitch and drops and inserts the full bobbin in the magazine into the bottom of the take-up weight,
The full bobbin 91 that has fallen from the magazine (not shown) is temporarily stopped in the guide chute 92, and then the full bobbin 91 is dropped and inserted into the peg 94 by opening the double door 193 provided at the lower end of the guide chute 92. A device has been proposed. As described above, in the conventional device, the full bobbin simply falls naturally and is inserted into the peg below, which causes the problem that the attitude of the full bobbin becomes unstable and the insertion into the peg becomes uncertain. In particular, when using natural fall when inserting a full bobbin into a peg that moves relatively at a constant speed, there is a problem in that it is very difficult to match the timing of the fall.

(Problems to be Solved by the Invention) The present invention solves the problems in the conventional apparatus, such as the uncertainty in inserting a full bobbin and the difficulty in timing the insertion with respect to a relatively moving peg.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, in the present invention, a pair of gripping members for gripping a full bobbin are arranged to be openable/closable and movable up and down, and both gripping members Means is provided for holding the member in a closed state in its upward movement position and for opening both gripping members after the lower part of the full bobbin gripped by both gripping members is partially inserted into the bed during its downward movement. We adopted a configuration in which

(Operation) In the device of the present invention, a full bobbin is gripped by a pair of gripping members that are held in a closed state in the upward movement position. The gripping member gripping the full bobbin is moved downward, and both gripping members are opened during the downward movement when the lower part of the full bobbin is partially inserted into the peg below. In other words, since a full bobbin is held by both gripping members until its lower part is partially inserted into the peg, the bobbin can be inserted into the peg reliably unlike insertion by natural fall, and the downward movement speed of the gripping member can be increased. This reduces insertion time.

One end thereof is connected via a link 54 to a lever 53 fitted to the rotating shaft 44, and is rotated in conjunction with the shutter 42.

Next, the full bobbin insertion device 19 will be described. The tip of a swinging lever 56 whose base end is rotatably supported by a support shaft 55 has an upper portion shaped like a flat opening at a position below the bobbin shooter 20. A support bracket 57, which is bent as shown in FIG. Above the base end of the swing lever 56, a swing lever 58 formed in a substantially L-shape is rotatably supported at its bent portion by a support shaft 59.

The swinging lever 58 has one end connected to the swinging lever 56 by a link 60, and the other end is rotatable integrally with a rotating shaft 64 that is rotated from the shaft 26 via a pulley 61, a belt 62, and a pulley 63. A cam ball 58a that engages with the fitted cam 65 is attached. Swing lever 5

Support shafts 67a and 67b are each rotatably supported via the support shafts 67a and 67b. At one end of the support shafts 67a, 67b (on the side in the direction of movement of the doffing machine), there are levers 68a, 68b, respectively.
a and 67b so that they can rotate together. Both levers 68a and 68b have links 69 at their tips.
Each end is connected to a bottle so that they can rotate in opposite directions. At the center of both support shafts 67a and 67b are gripping members 7a and 7 for gripping the full bobbin 17, respectively.
0b is attached to be able to rotate integrally with the support shafts 67a and 67b. The lower ends of both gripping members 70a and 70b are bent inwardly, and a full bobbin 17 fed from the bobbin shooter 20 is placed on the opposite side to the support bracket 57 (opposite to the direction of movement of the doffing machine 1). Covers 71a and 71b are provided to prevent the objects from popping out. An engagement lever 72 is fitted onto the other end of one of the support shafts 67a so that it can rotate integrally with the support shaft 67a, and a hooking member 73 is fitted onto the other end of the other support shaft 67b so that it can rotate together with the support shaft 67b. can be fitted,
One end of a screw spring 74, which has one end hooked to the mounting bracket 66b, is hooked to the hooking member 73, and the other end of the screw spring 74 is hooked to the hooking member 73, thereby biasing the gripping member 70b to rotate toward the closed position. An engagement pin 75 is fixedly provided below the engagement lever 72 at a predetermined position where it can be engaged when the lower end of the full bobbin 17 held by the gripping members 70a and 70b is partially inserted into the peg 16a. ing.

Next, the operation of the apparatus configured as described above will be explained. When the fine Ih machine is stopped by a full tube command, the motor 9 of the doffing Ia1, which is carried by a carrier (not shown) to a position corresponding to the full tube machine stand, is driven, and the screw row 58 is rotated to close the groove 8a. The doffing machine 1 starts moving along the rail 2 by the engagement of the doffing machine 1 with the bin 7. When the shaft 26 approaches the first spindle 6, the shaft 26 is rotationally driven via the clutch 27, and the cam mechanism 21 of the full bobbin lifting device 18
is activated, the elevating member 23 is lowered and raised, and the bobbin gripping device 24 pulls out the full bobbin 17 from the spindle 6. The bobbin gripping device 24 is horizontally moved rearward (to the left in FIG. 1) as it moves upward, and is located at a position corresponding to the bobbin shooter 20. In this state, the grip release rod 76
is moved downward, and the full bobbin 17 held by the bobbin gripping device 24 is released from the bobbin gripping device 24 and falls into the bobbin shooter 20. When the full bobbin 17 falls into the bobbin shooter 20, the thread connected to the full bobbin 17 from the spindle 6 is guided by the groove 38a of the side plate 38 and led to a thread cutter (not shown) where it is cut.

The full bobbin 17 that has fallen into the bobbin shooter 20 is tilted and is actively conveyed downward in the upstream passage 41a by the belt conveyor 40. When the base end of the full bobbin 17 comes into contact with the conveyor belt 43 disposed at the bending part of the passage, the base end of the full bobbin 17 is actively sent downward by the action of the conveyor belt 43 and its posture becomes vertical. It is placed on the shutter 42 disposed at the lower end of the downstream passage 41b. Next, the rotating lever 50 is rotated clockwise in FIG. 1 about the support shaft 48 by the action of the cam 49, and the shutter 42 is opened. Also, in conjunction with this, the lever 53 is rotated,
The hammer 51 rotates from the position shown by the solid line in FIG. 1 to the position shown by the chain line to actively feed the full bobbin 17 to the full bobbin insertion device 19 disposed below. The full bobbin 17 sent out from the bobbin shooter 20 is held by both gripping members 70a and 70b in the upward movement position as shown by chain lines in FIG.
is grasped by. From this state, the cam 65 is rotated, the swing lever 58 is rotated clockwise about the support shaft 59, and the swing lever 56 is rotated in the same direction (clockwise) via the link 60, and both gripping members 70a .

70b is moved downward while holding the full bobbin 17 together with the support bracket 57. And full bobbin 17
The engagement lever 72 starts to engage with the engagement pin 75 during the downward movement when the lower part of the engagement lever 72 is partially inserted into the bed 16a. As the support bracket 57 further moves downward from this state, the engagement lever 72 is rotated clockwise together with the support shaft 67a. Then, the lever 68a is connected to the support shaft 67a.
At the same time, the lever 68b is rotated counterclockwise via the link 69. As a result, the gripping members 70a and 70b are rotated outward to release the gripping state of the full bobbin 17, and the full bobbin 17 is inserted into the hook 16a. That is, since the full bobbin 17 is actively moved downward while being held by both gripping members 70a and 70b and inserted into the peg 16a, the peg 1
Insertion into 6a is done quickly and reliably.

In this embodiment, since the sliding body 16 is disposed so that the pitch of the pegs 16a is approximately equal to the pitch of the spindle 6, the doffing machine 1 continuously moves the pegs 16a.
When inserting full bobbins 17 one after another on the peg 16a, it is necessary to pick up the full bobbins 17 from the bobbin shooter 20 before the full bobbin insertion device moves to the position corresponding to the next peg 16a.

However, if the sliding body 16 into which the full bobbin 17 has been inserted and the sliding body 16 into which the next full bobbin 17 will be inserted are placed adjacent to each other, the full bobbin 17 that has already been inserted into the peg 16a will be inserted next. Since receiving the full bobbin 17 inserted into the bobbin chute 20 becomes an obstacle, in the apparatus of this embodiment, a sliding body feeding device (not shown) moves the sliding body 16 from the spindle after the full bobbin 17 is inserted. The doffing machine 1 is sent to the opposite side of the moving direction by the pitch. Even after the grip on the full bobbin 17 is released, the full bobbin 17 is moved from the position corresponding to both gripping members 70a and 70b by the movement of the sliding body 16 in which the full bobbin 17 is inserted into the peg 16a by the sliding body feeding device. The large diameter portion of the cam 65 comes into contact with the cam ball 58a to hold the support bracket 57 in the downward movement position, and both gripping members 70a
, 70b are held open. Next, the engagement between the large diameter part of the cam 65 and the cam ball 58a is completed, and the cam ball 58a comes to engage with the small diameter part of the cam 65, and the swing lever 58 is rotated counterclockwise, and the swing lever 58a is rotated counterclockwise. 56 is also rotated counterclockwise, and the support bracket 57 is moved upward. Then, due to the upward movement of the support bracket 57, the engagement between the engagement lever 72 and the engagement pin 75 is released, and the lever 68tl is rotated clockwise by the action of the screw spring 74. are rotated counterclockwise, both gripping members 70a and 70b
returns to closed state. Thereafter, the full bobbins 17 are sequentially pulled out from the spindle 6 in the same manner as described above, and are passed through the bobbin shooter 20 and the full bobbin insertion device 19 to the peg 16a.
inserted into.

Note that the present invention is not limited to the above-mentioned embodiment, and for example, as shown in FIGS. 6 and 7, a lever 7 slidably supported on a guide rod 77 instead of the swinging lever 56
A support bracket 57 may be fixed to 8. Furthermore, the present invention can be applied not only to an automatic doffing machine but also to other spinning machines, such as a device for inserting full bobbins into a winder, etc., and the shape and structure of each part can be arbitrarily changed without departing from the spirit of the present invention.

Effects of the Invention As detailed above, according to the present invention, the receiver at the upper position, while gripping the picked up full bobbin, moves downward to the vicinity of the peg located at the lower position to insert the full bobbin into the peg. To provide an excellent effect that the insertion work can be performed quickly and reliably, and the full bobbin can be surely inserted into the peg even in a state where the full bobbin insertion device and the peg move relative to each other.
