Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a conveying device for smoothly transporting yarn or yarn intermediate products in the textile industry during production, processing, and treatment processes. The winding of the yarn or yarn intermediate product to be wound is carried by a simple device together with the bobbin in a free direction and at regular intervals. It can also be used as is for transporting lightweight objects that have holes.

[Conventional technology]

In the textile industry, yarn or yarn intermediate products are mainly wound onto hollow bobbins with a through hole in the center and loaded onto machinery for the next process or processed. FIG. 2 (illustrative sketch) illustrates typical yarn formations in the spinning process, where R indicates roving, C indicates tube yarn, and CH indicates cheese thread. In particular, since the roving R and the pipe C need to be sequentially supplied to a finishing machine, a rewinding machine, etc., various conveying means and devices are used. In the past, transport carts and transport boxes were used as means for this purpose, but since they tend to stain the product and disrupt the thread layers of the spool, and require human labor, automatic transport and supply devices have been used in recent years. These spools may be moved a short distance during the processing process, and methods such as rolling or pushing are used, but there is a risk of staining the yarn or disturbing the yarn layer. . FIG. 3 is an explanatory diagram showing an example of a conveying means for the tube yarn C, in which the tube yarn conveying path is constituted by a belt conveyor 5, and the conveyor 5 is provided with a tube receiving insertion vest 5.
a are planted at regular intervals, and the supply pipes Ca are dropped and guided to the pegs 5a to be supported and conveyed by the movement of the belt conveyor 5. And on the take-out side, for example, there is a tube box 6.
While pulling out the tube thread C, I put it in and store it. Since the conveying path in such a conveying device is constituted by a flat belt, it has the disadvantage that it can only be constituted in a single row and in a nearly straight line.

Therefore, it cannot be used for a curved or inclined conveyance path, and it cannot be used, for example, in a conveying means where the pipe is fed at irregular intervals on the supply side and taken out at regular intervals on the take-out side, or when it is fed at constant or irregular intervals and is desired to be taken out at irregular intervals on the discharge side. Alternatively, the flat belt-type conveyor 5 may be used as a conveyance means to follow the pipe yarn to be taken out on the take-out side and send it to the take-out position, or to stop or set it at free speed during conveyance, or to take out at the free position. Not available.

[Problems to be solved by the invention] Therefore, the inventors of the present invention have proposed that the pipes, etc., be received at regular intervals or irregular intervals, and transported sequentially, and that the unloading section sequentially transports the yarns as they are unloaded. As a result of our study, we considered whether it would be possible to create a conveying device that automatically sends the pipe yarn, etc. to its take-out section, and in which the bending and inclination of this conveying path can be freely selected, with a simple configuration. It has been reached.

[Failure to solve the problem]

The present invention is a conveying device for hollow bobbins for thread winding, in which a plurality of bobbin mounting pallets each having a base having a diameter larger than the outer diameter of the thread winding are disposed in a guide gutter, and the pallets are supported in the guide gutter. The gist lies in that a round belt is arranged, and the pallet is moved by driving the round belt.

[Function and Examples]

FIG. 1 (partial perspective view) is a sketch of the main parts of the bobbin conveying device 1 for bobbin winding of the present invention, showing a guide trough 2, a rubber belt 3 with a round cross section, and a large number of rubber belts (only one is shown in the figure) that fit within the guide trough 2. The pallet 4 is constructed as shown in Fig. 7 (
As shown in the cross-sectional view), a part of the bottom plate is supported by a round belt 3. The guide trough 2 is composed of side walls 2at2b, each of which has a U-shaped portion and leg walls 2c, 2c for guiding a base portion of a pallet 4, which will be described later. Then, the base 8 is interposed between the leg walls 2c, 2c and assembled by tightening with bolts 9, and the round belt 3 is supported by the base 8 and a part of the outer peripheral surface of the round belt 3 is formed into a guide trough. The bottom surface of the U-shaped part 2 is also slightly protruded. Since the round belt 3 is preferably made of an elastic material, the amount of protrusion is determined by taking into consideration the amount of deformation due to the weight of the pallet 4 and the loaded spool. Let them do it. In addition, the guide trough 2 is used as a guide trough 2 for inserting the pallet 4 or for taking it out.
As shown in the figure (sectional view), a portion of the upper wall of the U-shaped portion may be removed. Also, Koro may be used as Origin 8.

On the other hand, the pallet 4 is shown in FIG. 4 (partial cross-sectional side view) in which the tube yarn C is held, and the base 4b and the tube yarn bobbin 7 are formed to have a larger diameter than the winding outer diameter of the tube yarn C. It is constructed by forming a pin 4a, which is inserted into a hollow hole, approximately at the center thereof, and the tip of the pin 4a is sharp to facilitate insertion of the bobbin 7. Note that the conveying device of the present invention is a pallet 4.
Since this is a pressing type conveying means, the pallet 4 housed in the guide trough 2 is in contact with the round belt 3, as schematically shown in Fig. 5 (side view) and Fig. 6 (plan view). It moves by belt drive, but if the movement is stopped by the preceding pallet or a restricting object, only the pallet will stop and the round bell) 3
f''1jff continues to move. Therefore, when pallet movement is not restricted in any way, they move together with the round belt 3,
At the take-out section, the pallets sequentially stop circumscribing the preceding pallets, the interval between which is determined by the outer diameter of the base 4b of the pallet, and the spools are arranged so as to maintain a specific gap and wait for take-out. Although the shape of the base 4b of the pallet 4 is shown to be circular, it may be square, hexagonal, etc., and the key is to fit it within the guide trough 2, move smoothly, and follow the curved guide trough. It is fine as long as it is something.

On the other hand, the round belt 3 disposed inside the guide trough 2 is placed on either side of the center of the guide trough 2 (to the left in the figure), as shown in FIGS. 7 and 8 (plan views). The base 4b of the pallet 4 is supported by the bottom side of the side wall 2b and the top surface of the round belt 3.

Therefore, the pallet 4 is stably supported and supports the loaded tubes and the like almost vertically. Moreover, when it is desired to incline the pipe thread, etc., the guide trough 2 may be inclined. Fig. 10 (side view) shows the moving state of the pallet 4 on the left side of Fig. 8 with a part of the guide trough 2 cut away. When this happens, only the round belt 3 slides on the bottom of the pallet and the pallet 4 is stopped.

Therefore, the pallets 4 move according to the moving speed of the round belt 3, but when their movement is restricted by the preceding pallet or the regulating member, they are lined up in the guide gutter 2 with no gap in the direction of movement, and as soon as this gap is formed, It moves to fill this space. On the other hand, the conveyance path of the conveyance device constituted by such a guide trough 2 and round belt 3 is shown in FIG. 11 (schematic cross-sectional view).

It is also possible to use a double loop type in which J 11 and 11 (one not shown) are arranged horizontally, the round belt 3 is made into a horizontal loop, and guide troughs 2 are arranged on the outward and return routes, respectively. In addition, in the case of such a loop type, both end sides have both side walls 2a, 2 as shown in Fig. 13 (developed sketch).
b may be semicircular side walls 2aa and 2bb, respectively, and a support seat 12 may be attached to the inner side wall 2bb to pivotally support the guide drive pulley 11. Also, if a height difference is required on the outbound and return trips, tilt the drive guide pulley as shown in Figure 14 (schematic cross-sectional view). It should be Jlla. On the way out again.

When the interval on the return path is required, the round belt 3 is moved around the guide pulleys 13° 13.13, as shown in FIG. 15 (schematic diagram).
13 and any of the guide pulleys may be of a positive drive type, and if necessary, a guide trough may be provided between each guide pulley to form a closed loop. Although not shown, it is triangular.

You can freely set polygonal shapes, etc. Furthermore, although these are linear and horizontal types, they can be freely designed with curved conveyance paths or vertical conveyance paths. Fig. 16 (schematic diagram) shows an example of a combination of these, where 14 is a horizontal bending part, 15 is a rising part, and if the guide trough 2 is provided oppositely to each of them, the pipe thread etc. can be moved to a free position. can. Although the figure shows a case where the conveyance speed is constant, if these loops are placed next to each other and the pallets are transferred, the conveyance speed can be changed and the pallet can be further transferred to a free position.

Further, on the replenishment side of the conveyance path, a curved riser &112g similar to the curved descending gutter 2f connects the lower side fence 2e and the upper side fence 2d, and carries the pallet 4 pushed out from the lower side fence 2e to the upper side. It has been moved to side fence 2d. Note that this curved ascending gutter 2g is used when the pallet 4 is tilted so that it cannot be pushed up sufficiently by the push-out force due to the contact pressure with the round belt 3. It is recommended that the pallet 4 be provided in a straight line portion of 2g so that the pallet 4 discharged from the lower side fence 2e is reliably raised and transferred to the upper side fence 2e.

The bobbin conveying device configured in this manner is, for example, provided in a rewinding machine for a long time along the length direction of the machine base, and is used to transport the empty pallet 4 on the upper rail 2e in the yarn supply section 18.
is temporarily stopped, the new tube yarn C is dropped into the peg of the pallet, and is sequentially transferred in the direction of the arrow. In the take-out section 19 that requires supply of the pipe thread, the pipe thread is extracted from the pallet 4 using a pipe take-out and supply device 20 as schematically shown, and is supplied to a predetermined portion. As shown schematically, this pipe yarn take-out and supply device 20 has a semi-cylindrical lifter 21 equipped with a pallet hooking and stopping fork at its lower part. The pipe reaches the bottom of the thread bobbin.

Next, the lifter 21 ascends in the direction of arrow B to pull out the tube yarn from the pallet 4, and then lifter holding stand 2
