Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a tray conveying belt and a manufacturing method thereof.

[Prior art] In recent years, in spinning factories, the spinning process and the wind mite stage are directly connected by a conveying means, and when the full bobbin doffed in the fine grain process is transported to the wind mite stage, the yarn is wound up in the wind mite stage. A method is often adopted in which the empty bobbin is transported again to the precision process and used as a ring.
The conveyance method using a lay is more advantageous in terms of m#1m elementation than the method using a bell l-conveyor. As a conveying means for this peg tray, for example, Utility Model Publication No. 61-20247
As disclosed in Publication No. 1 or Japanese Unexamined Patent Publication No. 62-27278, a peg tray is inserted between a pair of opposing guide rails having a U-shaped cross section, and in this state, the lower side of the peg tray is placed on a conveyor belt. A method of conveying the material by hand is generally adopted.

However, in the conventional conveyance method, the peg tray is simply placed on the conveyor belt, so when providing an inclination to the conveyance path, it is limited to a gentle slope, which leads to a shortening of the conveyance path. It was impossible to transport the robot in any position.

As a device to eliminate this inconvenience,
Publication No. 882 discloses that a transmission belt (conveyor belt) is stretched along a desired path via a belt guide and a guide boob, and is moved by a drive. A conveying device is disclosed that is provided along the guide and conveys the peg tray by driving the transmission belt while the peg tray is elastically compressed between the guide and the transmission belt.

[Problems to be Solved by the Invention] In order to reliably transport the peg tray while following the movement of the transport belt regardless of the travel path of the transport belt, it is necessary to increase the frictional resistance between the transport belt and the peg tray. There is a need to. In the device disclosed in the above-mentioned Japanese Patent Application Laid-Open No. 62-180882, the entire conveyor belt is made of the same material, so in order to ensure the conveyance of the peg tray, a material with a large friction coefficient is used for the conveyor belt. There is a need. However, if the conveyor belt is made of a material with a large coefficient of friction, the frictional resistance between the conveyor belt and the belt guide will increase, and not only will more conveyance power be required, but the e! There is a problem that wear of the conveyor belt and belt kite due to friction progresses in a relatively short period of time.

The present invention has been made in view of the above problems, and includes:
The purpose is to provide a tray conveyance belt that can reliably convey a peg tray for bobbin conveyance or a tray on which other conveyed objects are placed not only in the same plane but also along a three-dimensional conveyance path, and a method for manufacturing the same. There is a particular thing.

[Means for Solving the Problems] In order to achieve the above object, in the present invention, a low 1! IF! ! 3 where the sliding zone layer is arranged
The sliding contact band layer is located inside the contact conveyance band layer on one end side in the width direction of the belt, and the edge of the surface contact conveyance band layer is located between the sliding contact band layer and the other end side. It was formed obliquely toward the edge of the interface.

Also, 2! is made up of a high friction contact conveyance band layer that contacts the bottom surface of the tray that supports conveyed objects, and a low friction sliding contact band layer that has the same width as the contact conveyance band layer. gJ structure, at one end of the belt in the width direction, the end of the contact conveying band layer is inclined toward the end of the interface with the sliding band layer, and at the other end of the sliding contact band layer. The end portions may be formed obliquely toward the end portion of the interface with the contact conveyance layer.

A method for manufacturing a three-layer conveyor belt includes a high-friction contact conveyance belt layer and a low-friction sliding contact belt layer, the sliding contact belt layer is sandwiched between the contact conveyance belt layers, and the width The layers are formed in such a way that one end side in the direction is almost flat, and the corner of the contact conveyance band layer is cut off diagonally so that the end face of the contact conveyance band layer is located inside the end face of the sliding contact band layer on the one end side. There is a way.

[Function] When the tray conveyance belt of the present invention is used, the conveyor belt is moved along the desired conveyance path with the low-friction sliding band layer in contact with the urging member that presses the conveyor belt toward the tray side. It is stretched along the line. The tray is arranged so that its top surface is in sliding contact with the two guide members and its bottom surface is in contact with the high-friction contact conveying belt layer of the tray conveying belt, and is always in contact with the contact conveying belt layer of the tray conveying belt. It moves together with the tray conveyance belt in a state of contact. Since the tray conveyance belt contacts the biasing member at the sliding band layer with low II friction,
Wear of the belt and biasing member is reduced, and reliable tray conveyance is maintained over a long period of time.

In addition, in the method for manufacturing a tray conveying belt, high I:
l In order to form one end surface of the low-palm-rubbing sliding band layer sandwiched between the contact-carrying band layers and protruding from the end surface of the contact-carrying band layer, a corner portion of the contact-carrying band layer is formed. Since the method of cutting off the tray diagonally is adopted, the tray conveying belt can be formed extremely easily.

After being transported to a position 'fl corresponding to the peg tray delivery plate 11, it is delivered onto the conveyor belt 7. The conveyor belt 13 of the torsional conveyor 15 has a portion running parallel to the conveyor belt 7 at approximately the same height and a portion running parallel to the lower part of the spindle 8 at approximately the same height.
It is wound around a large number of guide pulleys 16 so as to have a portion that runs parallel to the spindle rail 6 above the full bobbin F on the spindle 8, and a portion that runs parallel to the conveyor belt 7 that runs parallel to the pipe changer 1. is set to match the direction of travel.

In the center of the tube puller 1, a running body 17 is supported on one support shaft 18° so as to be slidable in the running direction of the up tube change fit, and an empty bobbin conveyed above the full bobbin F on the spindle 8. Remove the empty bobbin E from the attached peg tray 9A, and also remove the full bobbin F. An empty bobbin extracting/inserting device 20 inserts an empty bobbin E into a spindle 8 that is empty, and a bevel 9a of a peg tray 9 that is pulled out of a full bobbin F from the spindle 8 and is fed m to the same height 1 as the lower part of the spindle 8. The traveling body 17 is equipped with a full bobbin extraction/insertion device 21 for inserting a full bobbin into the bobbin. The traveling body 17 is reciprocated via a cam lever 23 that is reciprocated by a cam 22 that is operatively connected to the screw roller 5, and the empty bobbin gripping device 2 constituting the empty bobbin extracting and inserting device 20 is moved.
The support arm 25 of No. 4 has its support shaft 26 and a gear f (not shown).
The support arm 28 of the full bobbin gripping device 27, which is operatively connected to the screw roller 5 through the i411 and the cam mechanism and constitutes the full bobbin extraction and insertion device 21, also has its support arm 29,
It is operatively connected to the screw roller 5 via a gear mechanism and a cam mechanism (not shown). As a result, the empty bobbin extracting/inserting device 20 and the full bobbin extracting/inserting device 21 are driven in synchronization with the reciprocating movement of the traveling body 17. Note that 30 (shown in FIG. 3) is a support member that supports the top of the empty bobbin E on the peg tray 9A with empty bobbins held by the empty bobbin extraction/insertion device 20, and 31 is driven by a rotary solenoid 32 to convey it. This is a peg tray position regulating piece that can be rotated on the path.

As shown in FIG. 1, the flat belt constituting the conveyor belt 13 is made of a hard material with a small coefficient of friction such as nylon between high-frictional contact conveyance belt layers 13a made of a material with a large coefficient of friction such as soft rubber. A low-friction sliding band layer 13 formed of
The sliding contact layer 13b is located inside the contact conveying belt layer 13a at one end side in the width direction of the conveyor belt 13 (the upper side in FIG. 1), and the contact conveying belt layer 13b is located at the other end side The ends of both contact conveyor belt layers 13a are slidably connected to the contact belt layer 13.
It is formed obliquely toward the end of the interface with b. A pair of guide pieces 33 for guiding the conveyor belt 13 to move along a desired conveyance route are fixed to the rear wall 1a of the tube changer mi with screws 34 at appropriate intervals. The guide member 14 is fixed to support brackets 35 fixed at appropriate intervals along the travel path of the conveyor belt 13, and the peg tray is placed between the conveyor belt 13 and the guide member 14 so as to sandwich the begs 9a of the peg tray 9. 9 is arranged so as to be held between the two. Between the guide pieces 33, a slide guide 36 that contacts the sliding layer 13b and guides the conveyor belt 13 presses and biases the conveyor belt 13 in its width direction, that is, toward the guide member 14 by the action of a pressing spring 37. It is located in

Next, the operation of the apparatus configured as described above will be explained. When the spinning machine stops due to a full tube command, the tube changer R1 that had been stopped at the end of the frame starts running at a constant speed, the motor 12 of the torsional conveyance device 15 starts driving, and the conveyor belt 13 moves to the second, Start moving in the direction of the arrow in Figure 3. Under this state, the empty bobbin-equipped peg tray 9A on the conveyor belt 7 is taken into the pipe changer 1 by engagement with the peg tray intake plate 10. The peg tray 9A with an empty bobbin taken into the tube drawer 1 has a bevel 9a introduced between the guide members 14 arranged near the peg tray intake plate 10, and changes from a vertical position to an almost horizontal position according to the torsion shape of the guide member 14. tilted. As a result, the bottom surface of the peg tray 9A with empty bobbins comes into contact with the edges of the pair of contact conveyance band layers 13a constituting the conveyance belt 13, and receives a pressing action from the conveyance belt 13 toward the guide member 14 by the action of the pressing spring 37. . Therefore, the peg tray 9A with an empty bobbin is pressed against the contact conveyance belt layer 13a of the conveyor belt 13 by the reaction force from the guide member 14, and the tube changer R is held in a horizontal position by the cooperation of the conveyor belt 13 and the guide member 14.
1 is transported upward.

Peg tray 9 with empty bobbin transported above tube changer 1
A is subjected to the position regulating action of the position regulating piece 31, and under this condition, the empty bobbin E on the peg tray 9A with an empty bobbin is extracted from the peg 9a by the empty bobbin extracting/inserting device 20. Then, while the traveling body 17 travels in the direction opposite to the traveling direction of the tube changer R1, the full bobbin F on the spindle 8 is pulled out by the full bobbin pulling and inserting device 21, and
The empty bobbin E extracted by the empty bobbin extraction/insertion device 20 is inserted onto the spindle 8. During this time, empty bobbin E
The peg tray 9 from which the peg tray 9 has been removed is conveyed to the conveyance path at a height position corresponding to the spindle rail 6 by the cooperation of the conveyor belt 13 and the guide member 14.
Under the position regulating action of the position regulating piece 38 of -E, the full bobbin F pulled out by the full bobbin pulling up and insertion device 21 is inserted into the bed 9a. This full bobbin peg tray 9
B is conveyed to the peg tray delivery plate 11 by the cooperation of the conveyor belt 13 and the guide member 14, and the full bobbin F is suspended from the horizontal position due to the twisted shape of the guide member 14 in the vicinity and the engagement with the peg tray delivery plate 11. It is changed into a standing position and delivered onto the conveyor belt 7.

Only the edge of the high-friction contact conveyance band layer 13a contacts the bottom surface of the peg tray 9A with empty bobbins, which is conveyed upward by the cooperation of the conveyance belt 13 and the guide member 14, and the slide guide 36 has a low-friction Only the edges of the sliding contact layer 13b are in contact with each other. With such a contact configuration, the pressure spring 3 has a spring characteristic that can generate the large frictional resistance required between the bottom surface of the peg tray 9A with empty bobbins and the conveyor belt 13.
7, the frictional resistance in the contact region between the slide guide 36, which receives the transmission of the pressing action of the pressing spring 37, and the sliding band H113b can be suppressed to a low value. Therefore, as the conveyor belt 13 travels, the peg tray 9A with empty bobbins is conveyed while reliably following the conveyor belt 13. Moreover, the slide guide 36 and the conveyor belt 13
The effect of preventing wear between the two is also greatly improved.

Embodiment 2] Next, an example of a method for manufacturing the conveyor belt 13 having the above structure will be described with reference to FIG.

The manufacturing process of the conveyor belt 13 is as follows: First step (Fig. 5 (a)): Three belt-shaped members made of a material with a large friction coefficient such as rubber constituting a high-friction contact conveyance belt layer, and a low-friction The band member 3 is made of a hard material with a small friction coefficient such as nylon constituting the M band layer.
9, with the narrow strip member 40 sandwiched between three strip members, and both side edges of the strip member 40 are inside the side edges of the two strip members 39. Step 2 (FIG. 5(b)): Step of separating the strip members 41 stacked in three layers from the center to form two belts 42; Third step (FIG. 5(b)) Figure (c)): Consists of a step of obliquely cutting off the corners of both contact conveyance bands N 13 a on the respective separated sides of each bell I 42.

Although it is relatively troublesome to form three M layers of strip members 39 and 40 and bond them together so that one side edge is flush with each other, in this embodiment, one layer of strip members 41 in three layers is used. A surface-to-surface structure can be easily formed by separating the two
The book belt 42 can be formed at one time. In addition, by a simple operation of cutting off the corners of the contact conveyance belt layer 13a having a rectangular cross section diagonally, the end face of the low friction sliding contact belt layer 13b at one side edge of the belt 42 can be aligned with the end face of the contact conveyance belt layer 13a. It will be in a state where it is located at the outermost side of the conveyor belt 13 in the width direction.

[Embodiment 3] Next, a third embodiment will be described according to FIG. 6. In this embodiment, instead of using a peg tray for conveying bobbins, the conveyor belt 13 is applied to a device that conveys a tray 44 having a recess 44a formed on the upper surface in which a conveyed object (bottle, can, etc.) 43 is placed. is different from the first embodiment. In this embodiment, as in the first embodiment, the conveyor belt 13 is biased by the pressing spring 37 via the slide guide 36 in the direction of pressing the tray 44 toward the kite member 14, and the conveyor belt 13 and the guide member 14 The object 43 is transported along a predetermined transport route while changing its posture.

Note that a leaf spring may be used as the pressure spring 37 instead of a coil spring.

Alternatively, as shown in FIG. 8, the conveyor belt 13 is formed into a two-layer #I layer of the contact conveyor belt layer t3a and the sliding contact belt layer 13b having the same width, and the conveyor belt 13 is brought into contact at one end side in the width direction. The end of the conveyor belt layer 13a is tilted toward the interface with the sliding belt layer 13b, and the end of the sliding belt layer 13b at the other end is tilted toward the end of the interface with the contact conveyor belt layer 13a. In addition, the edge of the slope 45 does not necessarily have to coincide with the edge of the interface between the two band layers 13a and 13b, as shown in FIGS. Contact conveyance zone layer 1
3a or the sliding contact strip layer 13b may be formed in a shape with a notched end.
, When manufacturing the conveyor belt 13 in which the belts 1' 113b are laminated in three layers, the belt 42 is formed so that both side edges are the same as shown in FIG. 10(a), and one part of the belt 42 is By cutting out the corner of the contact conveying band layer 13a obliquely at the curved edge and cutting out the end face of the sliding contact band layer 13b in a V shape at the other side edge, the cross-sectional shape shown in FIG. 10(b) is obtained. The conveyor belt 13 may be formed. When this manufacturing method is adopted, the belt-like member 39, 40 is formed wide and the belt-like member 41 bonded in three layers is cut into a large number of pieces. The conveyor belt 13 can be formed from the belt 42, making it easy to manufacture the belt 42 and, in turn, the conveyor belt 13.
