Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of application) The present invention relates to a conveying device for a peg tray carrying a full bobbin or an empty bobbin.

(Prior Art) As disclosed in JP-A-60-5247,
When a bobbin full of bobbins sent to the winder process is directly sent to the spinning process by a transporting means that directly connects the spinning process and the winder process, the transport method using a peg tray is simpler than the mechanism using a conveyor. It is advantageous. As a conveying means of the peg tray, for example, as disclosed in Japanese Utility Model Laid-Open No. 61-202471 or Japanese Patent Laid-Open No. 62-27278, a peg tray is inserted between a pair of opposing guide rails having a U-shaped cross section. In this state, a method in which the lower surface side of the peg tray is placed on a transfer belt and conveyed is generally adopted.

(Problems to be solved by the invention) However, when the peg tray is on the transfer belt only by its own weight, it is limited to the setting of the conveyance path with a gentle inclination, and the arbitrary posture of the peg tray leading to the shortening of the conveyance path. Transport is impossible. The elasticity of the transfer belt is used to push the peg tray against the guide rail to transfer the peg tray, which allows the peg tray to be transferred in any posture, but the transfer belt causes the peg tray to be transferred as friction resistance between the transfer belt and the peg tray. It is necessary to set the size so that the performance can be secured. As a result, the frictional resistance between the transfer belt and the belt guide also increases in the arbitrary posture conveyance state, and the abrasion of the transfer belt and the belt guide due to this friction nullifies the elastic action of the transfer belt in a relatively short period of time. .

Therefore, in the present invention, a transfer belt is arranged along a guide rail that guides the peg tray on its upper surface side, and
The transfer belt is supported by a guide block so that the transfer belt can be pressed against the lower surface of the peg tray, and the transfer belt is laminated in the thickness direction with a low friction sliding contact belt layer sandwiched between high friction contact transfer belt layers. Then, the contact transfer belt layer at one end of the transfer belt is used as a contact portion of a peg tray,
The slide contact layer at the other end of the transfer belt was used as the slide contact portion of the instruction guide.

(Operation) That is, the transfer belt is supported and guided by the guide block, and is pressed against the guide rail by the elasticity of the transfer belt itself or other appropriate biasing means, depending on the positional relationship between the guide rail and the transfer belt. It is transported in a fixed posture. Therefore, by appropriately setting the positional relationship between the guide rails and the transfer belt, the carrying posture of the peg tray can be appropriately selected, and the degree of freedom in setting the carrying path is significantly improved. In addition, the guide block has a laminated structure in which a material having a large frictional resistance is used for the portion of the transfer belt that comes into contact with the peg tray, and a material having a small frictional resistance is used for the portion of the transfer belt that is exclusively responsible for the sliding contact with the guide block. It is possible to efficiently transfer the peg tray while suppressing sliding wear between the peg tray and the transfer belt, and it is possible to maintain reliable peg tray transfer for a long period of time regardless of the posture of the peg tray.

Further, since there are contact transfer belt layers on both surfaces of the transfer belt, the peg tray and the contact transfer belt layer contact each other when the peg tray is on either side of the transfer belt. Therefore, the peg tray can be transported on an arbitrary path arranged three-dimensionally.

(Embodiment) An embodiment in which the present invention is embodied in a pipe changer will be described below.
It will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the pipe changer 1 is movably supported along a spinning machine base, and the pipe changer 1 travels along a rail 2 with pins 3 and drive motors protruding at predetermined intervals. It is performed by the engagement action with the screw roller 5 driven by the motor 4.

Similarly, one or a plurality of U-shaped guide base frames 19 are fixedly attached between the support base frames 17 on the transport path, and L-shaped stoppers 20 are fastened and opposed to both ends thereof. ing. Inside the guide base frame 19, a guide block 21 having a U-shaped cross section is provided in the groove 2.
The transfer belt 13 is slidably fitted via 1b so that the transfer belt 13 is slid and guided in the guide groove 21a of the guide block 21. As a result, even if the guide block 21 receives a sliding action as the transfer belt 13 travels, this sliding action is received by the groove 21b, and the guide block 21 is held at a predetermined position without following the transfer belt 13.

A coil-shaped pressing spring 22 is interposed between the front and rear ends of the guide block 21 and the rear wall 1a of the pipe changer 1 along the transport path, and the guide block 21 guides the guide member 14
It is biased to the side. The peg tray 9 is inserted between the guide member 14 and the transfer belt 13 with the peg 9a fitted between the guide members 14, and the transfer belt 13 is pressed against the lower surface of the peg tray 9 by the spring action of the pressing spring 22. At the same time, the upper surface of the peg tray 9 is pressed against the guide member 14. The stopper 20 is for preventing the guide block 21 from coming off until the transfer belt 13 is inserted into the guide groove 21a of the guide block 21, and may be removed after the transfer belt 13 is inserted.

The transfer belt 13, which is a flat belt, is formed by stacking a sliding-contact core band 13a made of a low-friction anti-cloth and a pair of contact-transport outer bands 13b made of a high-friction synthetic leather, which are offset in the width direction. Only the end edges of both contact-conveyance outer bands 13b are in contact with 9, and only the end edges of the sliding contact core bands 13a are in contact with the bottom surface of the guide groove 21a of the guide block 21.

On the rear wall 1a side of the pipe changer 1, the traveling body 23 is provided with support shafts 24, 25.
Is supported slidably in the traveling direction of the pipe changer 1, and the empty bobbin E is pulled out from the empty bobbin-equipped peg tray 9A conveyed above the full bobbin F on the spindle 8 and the full bobbin F is pulled up. Empty bobbin removing and inserting device 26 for inserting the empty bobbin E into the spindle 8
And pulling out the full bobbin F from the spindle 8,
The traveling body 23 is equipped with a full bobbin pull-up and insertion device 27 that is inserted into the peg tray 9 that is conveyed at the same height as the lower part of the spindle 8. The traveling body 23 is reciprocated by a cam lever 29 which is reciprocally rocked by a cam 28 operatively connected to the screw roller 5, and a support arm 31 of an empty bobbin gripping device 30 constituting an empty bobbin extracting / inserting device 26 has a support shaft 35 thereof. The support arm 33 of the full bobbin holding device 32, which is operatively connected to the screw roller 5 via a gear mechanism and a cam mechanism (not shown), and which constitutes the full bobbin lifting / inserting device 27, also has its support shaft 36, a gear mechanism (not shown). And the screw roller 5 via the cam mechanism.
Is operatively connected to. As a result, the empty bobbin removing / inserting device 26 and the full bobbin lifting / inserting device 27 are driven in synchronization with the reciprocating traveling of the traveling body 23, and the empty bobbin E is removed from the empty bobbin-equipped peg tray 9A conveyed upward and the spindle 8 is moved. To the full bobbin F from the spindle 8 and inserted into the peg tray 9. Incidentally, 37 is an empty bobbin E on the peg tray 9A with an empty bobbin which is gripped by the empty bobbin extracting / inserting device 26.
Is a support member for supporting the top portion of the peg tray position restricting piece 38 which is driven by a rotary solenoid 39 and can be rotationally arranged on the conveying path.

Now, when the spinning machine stops due to a full pipe command, the pipe changer 1 stopped at the machine base end starts traveling at a constant speed, and
The motor 12 of the twisting and conveying device 15 starts driving, and the transfer belt 13 starts moving in the direction of the arrow in FIGS. Under this state, the empty bobbin-equipped peg tray 9A on the conveyor belt 7 is taken into the pipe changer 1 by the engaging action with the peg tray intake plate 10. The empty bobbin-equipped peg tray 9A introduced into the pipe changer 1 has the peg 9a introduced between the twisted guide members 14 in the vicinity of the peg tray intake plate 10, and the peg tray 9A from the vertical posture to the horizontal posture according to the twisted shape of the guide member 14. Is tilted to. As a result, the lower surface of the empty bobbin-equipped peg tray 9A comes into contact with the edges of the pair of outer contact-conveying belts 13b forming the transfer belt 13, and the pressing spring 22 moves from the transfer belt 13 side to the guide member 14 side via the guide block 21. Receives the pressing action of. Therefore, the empty bobbin-attached peg tray 9A is pressed against the guide member 14 in the horizontal posture, and is conveyed above the pipe changer 1 in the horizontal posture by the cooperation of the transfer belt 13 and the guide member 14.

Only the edge of the highly frictional contact outer transfer belt 13b comes into contact with the lower surface of the peg tray 9A with an empty bobbin which is conveyed upward by the cooperation of the transfer belt 13 and the guide member 14, and the guide groove 21a of the guide block 21 is contacted. Only the edge of the low friction sliding contact core strip 13a contacts the bottom surface. With such a contact structure, the pressing spring 22 applied to the guide block 21 is
Is transmitted to the transfer belt 13 via the contact area between the bottom surface of the guide groove 21a and the end edge of the sliding contact core band 13a, and the end edge of the contact transfer outer band 13b contacts the bottom surface of the empty bobbin-attached peg tray 9A. It is transmitted to the empty bobbin-equipped peg tray 9A via the region, and the upper surface of the empty bobbin-equipped peg tray 9A is pressed against the pair of guide members 14. Therefore, even when the pressing spring 22 having a spring characteristic capable of generating a large frictional resistance required between the lower surface of the empty bobbin-attached peg tray 9A and the transfer belt 13 is employed, the pressing action of the pressing spring 22 is transmitted. The frictional resistance between the sliding contact area between the guide block 21 and the sliding contact core band 13a is suppressed to a low value.
Due to such a frictional relationship, the transfer belt 13 is smoothly guided by the guide block 2 at high speed, and the empty bobbin-equipped peg tray 9A follows the transfer belt 13 running at high speed without delay. Moreover, the effect of preventing wear between the guide block 21 and the transfer belt 13 is significantly improved.
