DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cleaning and bonding apparatus for a resin block reinforcing material for cleaning and bonding an aluminum alloy reinforcing material of a resin block of a block V belt used in a dry-type continuously variable transmission. About.

[0002]

2. Description of the Related Art A belt-type continuously variable transmission has been developed as a transmission for an agricultural machine such as a combine or a tractor and a transmission for an automobile from the viewpoint of improving operability during shifting and improving fuel efficiency. ing. This belt type continuously variable transmission is
A pulley with a variable groove interval is attached to each of the drive shaft and the driven shaft, and a V-belt is wound between the two pulleys, and the groove pitch of each of the pulleys is adjusted to change the rotation pitch, thereby continuously changing the rotation pitch. It is configured to change the speed.

As such a V-belt, for example, a pair of endless rubber tension bands, a fitting groove for fitting each of the tension bands on both sides in the belt width direction, and a contact portion for contacting the belt groove side portion of the pulley. Each block is formed by engaging a concave groove formed on the upper and lower surfaces of each tension band and a convex portion formed on the upper and lower surfaces of the fitting groove of each block with each other. There is known a so-called block V-belt in which the belts are locked at both tension bands and arranged side by side at a predetermined pitch over the entire length in the belt longitudinal direction.

The block V-belt receives the lateral pressure of the pulley in each block and transmits power in a tension band. The belt V-belt has better flexibility than conventional rubber V-belts and can withstand high side pressure. It has many advantages such as reduced weight and no need for lubrication as compared with the metal V-belt, and reduced noise.

[0005] As each of the above blocks, a type in which a reinforcing material made of an aluminum alloy is coated with a resin such as a phenolic composite material is used.

[0006]

The above-described resin block reinforcing material for a dry-type continuously variable transmission is usually manufactured by the following procedure. That is, as shown in FIG.
First, a plate-shaped aluminum alloy is stamped and pressed in a stamping press forming step P1 to form a reinforcing material. Then, after the formed reinforcing material is polished in the barrel polishing step P2, a surface treatment of the reinforcing material is performed in the cleaning and bonding processing step P3. Then, in a block forming step P4, the reinforcing material is coated with a resin by injection molding to complete a resin block. Here, the above-mentioned cleaning / adhesion treatment step P3 aims at dirt and degreasing cleaning, and alkali cleaning, soft water cleaning, removal of a blackening layer, and generation of a surface oxide layer, which are performed for the purpose of increasing the bonding area by appropriately roughening the surface. Washing, soft water washing, drying, blast cooling, adhesive treatment for reacting OH of water molecules with silanol groups on an aluminum oxide film, drying, and baking are performed in the following order. Have been done.

More specifically, as shown in FIG. 15, a large number of reinforcing members are put in a basket for cleaning on the first work table 101 (see step P31 in FIG. 15), and the basket for cleaning is placed in the alkaline cleaning apparatus 102. set. Then, the alkali cleaning device 102 is operated to perform alkali cleaning (see step P32 in the same figure). Next, in the first sink 10, after cleaning with soft water (see step P33 in the figure), acid cleaning is performed. This is performed by setting the basket for cleaning in the acid cleaning device 105 and operating the acid cleaning device 105 (see step P34 in the figure). Then, when the acid cleaning is completed, soft water cleaning is performed in the second sink 104 (see step P35 in the same figure). And
In the drying basket 106, the reinforcing material that has been subjected to the acid cleaning is transferred from the cleaning basket to the drying basket (Step P36 in FIG. 3), and the drying basket is transferred to the cleaning drying apparatus 10.
7 (see step P37 in the figure). When the drying of the reinforcing material is completed, the reinforcing material in the basket for drying is transferred to the net pad in the cooling stand 108, and the net pad is cooled by the cooling stand 1.
08 to cool the reinforcing material (step P3 in FIG.
8). After that, the reinforcing material is accommodated in a car for bonding processing, and bonding processing is performed in the bonding processing apparatus 109 (see step P39 in the figure). When the bonding process is completed, the reinforcing material is transferred from the bonding basket to the drying basket again, and the drying basket is set in the bonding drying apparatus 110, and hot air drying is performed. (See step P310 in the figure).
Then, after the drying is completed, the reinforcing material is transferred to the net pad again on the second work table 111 (see step P311 in the same figure) and set in the baking oven 112 (see step P312 in the same figure). The reinforcing material that has been baked in the baking oven 112 is supplied to the third workbench 113.
Then, it is transferred to an aluminum pad (see step P313 in the same figure), and this reinforcing material is stored in the desiccator 114 (see step P314 in the same figure).

As described above, each process is performed by a single processing device, and the operator transfers the reinforcing material to a different car and transports the reinforcing material to each processing device to perform each processing. . Therefore, there is an inconvenience that the operation becomes complicated. Further, since it is necessary to transfer the reinforcing material to a different car, for example, when simultaneously processing a plurality of types of reinforcing materials, the reinforcing material may remain in the cleaning basket. As a result, different types of reinforcing materials may be mixed.

In each of the above-mentioned processing steps, a processing time is set, and this time is managed by one timer in the apparatus.

However, since the transfer between the processing steps is performed by an operator, the time required for the transfer varies, so that the time set in each processing apparatus varies. As a result, there is an inconvenience that there is a possibility that the processing time for each work varies, and the quality varies.

The present invention has been made in view of such circumstances, and an object of the present invention is to simplify the work in the step of cleaning and bonding a block reinforcing material for a dry-type continuously variable transmission. Another object of the present invention is to surely prevent the mixture of different types of reinforcing materials, and also to prevent a variation in processing for each work.

[0012]

In order to achieve the above object, the present inventor aims at automating a series of operations in a cleaning and bonding process, and improves a car containing a reinforcing member and a baking apparatus. The present invention has been completed by making improvements and other improvements.

More specifically, the present invention provides a method of cleaning and bonding a reinforcing material of a resin block of a dry-type continuously variable transmission in which a number of blocks are juxtaposed at a predetermined pitch over an entire length of a belt in an endless tension band. Assuming an automatic cleaning and adhesion processing device for a resin block reinforcing material for a dry-type continuously variable transmission that performs processing, an alkali cleaning device for performing alkali cleaning of the reinforcing material, a soft water cleaning device for cleaning the reinforcing material with soft water, An acid cleaning device for performing acid cleaning of the reinforcing material, a drying device for drying the reinforcing material, a cooling device for cooling the reinforcing material, an adhesive processing device for performing the bonding process on the reinforcing material, and a baking process for baking the reinforcing material after the bonding process. A line in which the devices are arranged in order, and the line is configured to be movable along this line, and the plurality of reinforcing members are so arranged that the processing of each device is sequentially performed on the plurality of reinforcing members. There the contained accommodated basket is a device to identify matters that it comprises a loader for conveying sequentially to each device. In this case, the loader sequentially sets the storage car in each of the above-described devices, and the respective devices sequentially perform the respective processes, thereby performing the cleaning and bonding processing of the reinforcing material. For this reason, conventionally, the transport of the car performed by the worker is omitted, and the work is simplified.

Further, since all the processes from alkali cleaning to baking are performed in the same storage basket, the transfer of the reinforcing material is omitted, and the operation is simplified. In addition, since there is no transfer of the car, mixing of different types of reinforcing materials is reliably prevented.

Here, the "printing device" comprises, for a predetermined time, a slope disposed so as to cross the inside of the printing device and a substantially cylindrical storage basket rolling on the slope for a predetermined time. It may be configured to include a single feed mechanism that discharges one by one to the outside of the printing apparatus after the elapse. In this case, when the storage car is set on the upper part of the slope of the printing apparatus, the storage car rolls and automatically passes through the printing apparatus to perform the printing process.
At this time, the storage basket is kept in the baking device for a predetermined time by the one-piece feeding mechanism, and the baking process is reliably performed for the predetermined time.

In such a printing apparatus, it is preferable from the viewpoint of production efficiency that a plurality of storage baskets sequentially flowing in the line be stored in the apparatus and the printing processing be performed simultaneously.

In view of the above, as a third aspect of the present invention, the baking device is configured so as to accommodate a plurality of storage cars therein, and the number of timers corresponding to the plurality of storage cars is provided. Then, each timer may measure the processing time for each of the storage cars and control the one-piece feeding mechanism. In this case, each timer counts the processing time for each storage car, so that even if the time at which the storage car is put into the printing apparatus varies due to intermittent flow through the line, the time of the printing processing itself does not change. Can be reliably prevented from being varied.

As the "single feed mechanism", for example, when a slope is not provided, a conveyor may be arranged in a printing apparatus so as to transport the storage basket. On the other hand, when providing a slope,
A pair of cylinders having rods protruding on the slope surface may be arranged side by side along the slope, and a single feed mechanism may be configured by controlling the pair of cylinders. That is, if the rod of the front cylinder is retracted with the rod of the rear cylinder protruding, the first storage car rolls on the slope and is discharged out of the printing apparatus, while By engaging the storage cage with the rod of the rear cylinder, it is possible to prevent the storage cage from following the front storage cage and coming out of the printing apparatus. In this way, a single feed mechanism of the storage basket is realized.

Further, the one-piece feed mechanism is provided with, for example, a substantially L-shaped stopper member, and the stopper member is disposed horizontally so as to be rotatable about its substantially central position. One end and the other end of the stopper member may alternately project on the slope surface.

In this case, when one end of the stopper is projected, the leading storage car is locked with the one end to prevent its rolling. On the other hand, when the stopper member is rotated, the one end of the stopper is rotated. Is retracted from the slope surface, so that the leading storage car rolls on the slope surface and moves. On the other hand, since the other end of the stopper member projects on the slope surface, the second storage car is engaged with the other end, and the rolling of the second storage car is prevented. When the stopper member is rotated in the opposite direction to the above, the other end of the stopper member retracts from the slope surface, and the second storage car rolls. Since it protrudes upward, it engages with this one end and its rolling is prevented. In this way, the storage baskets are sent one by one. When such a stopper member is used, only one control device needs to be used, so that the number of parts can be reduced and the cost can be reduced.

[0021]

As described above, according to the apparatus for automatically cleaning and bonding a resin block reinforcing material for a dry-type continuously variable transmission according to the present invention, the cleaning and bonding process is automated, and the work is greatly simplified. Can be. In addition, it is possible to prevent the dispersion of the processing and to surely prevent the mixing of different kinds of reinforcing materials.

That is, as shown in FIG. 8, it is detected by the photoelectric tube 38b that the first storage car has been put into the oven 38, and at this time, the first timer starts counting. The first storage basket is discharged by operating the member 41a. This discharge is detected by the photoelectric tube 38c. When the first storage car is in the oven 38, the second storage car is loaded, and the processing time of the second storage car is counted by the second timer. In this way,
The first to fifth storage baskets are baked in the oven 38 and discharged after a predetermined processing time has elapsed, so that the time of the baking processing is managed. The sixth storage car is measured by the first timer. Thus, for example, in the case where only one timer is provided, if there is a variation in the loading time of the storage car, the processing time will vary. By providing a timer, even if the input time fluctuates (t in FIG.
1 to t4), it is possible to avoid the occurrence of variations in the processing time (see tc in the figure).

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic cleaning and bonding apparatus for a resin block reinforcing material for cleaning and bonding an aluminum alloy reinforcing material of a resin block of a block V belt used in a dry-type continuously variable transmission. About.

[0002]

2. Description of the Related Art A belt-type continuously variable transmission has been developed as a transmission for an agricultural machine such as a combine or a tractor and a transmission for an automobile from the viewpoint of improving operability during shifting and improving fuel efficiency. ing. This belt type continuously variable transmission is
A pulley with a variable groove interval is attached to each of the drive shaft and the driven shaft, and a V-belt is wound between the two pulleys, and the groove pitch of each of the pulleys is adjusted to change the rotation pitch, thereby continuously changing the rotation pitch. It is configured to change the speed.

As such a V-belt, for example, a pair of endless rubber tension bands, a fitting groove for fitting each of the tension bands on both sides in the belt width direction, and a contact portion for contacting the belt groove side portion of the pulley. Each block is formed by engaging a concave groove formed on the upper and lower surfaces of each tension band and a convex portion formed on the upper and lower surfaces of the fitting groove of each block with each other. There is known a so-called block V-belt in which the belts are locked at both tension bands and arranged side by side at a predetermined pitch over the entire length in the belt longitudinal direction.

The block V-belt receives the lateral pressure of the pulley in each block and transmits power in a tension band. The belt V-belt has better flexibility than conventional rubber V-belts and can withstand high side pressure. It has many advantages such as reduced weight and no need for lubrication as compared with the metal V-belt, and reduced noise.

[0005] As each of the above blocks, a type in which a reinforcing material made of an aluminum alloy is coated with a resin such as a phenolic composite material is used.

[0006]

The above-described resin block reinforcing material for a dry-type continuously variable transmission is usually manufactured by the following procedure. That is, as shown in FIG.
First, a plate-shaped aluminum alloy is stamped and pressed in a stamping press forming step P1 to form a reinforcing material. Then, after the formed reinforcing material is polished in the barrel polishing step P2, a surface treatment of the reinforcing material is performed in the cleaning and bonding processing step P3. Then, in a block forming step P4, the reinforcing material is coated with a resin by injection molding to complete a resin block. Here, the above-mentioned cleaning / adhesion treatment step P3 aims at dirt and degreasing cleaning, and alkali cleaning, soft water cleaning, removal of a blackening layer, and generation of a surface oxide layer, which are performed for the purpose of increasing the bonding area by appropriately roughening the surface. Washing, soft water washing, drying, blast cooling, adhesive treatment for reacting OH of water molecules with silanol groups on an aluminum oxide film, drying, and baking are performed in the following order. Have been done.

More specifically, as shown in FIG. 15, a large number of reinforcing members are put in a basket for cleaning on the first work table 101 (see step P31 in FIG. 15), and the basket for cleaning is placed in the alkaline cleaning apparatus 102. set. Then, the alkali cleaning device 102 is operated to perform alkali cleaning (see step P32 in the same figure). Next, in the first sink 10, after cleaning with soft water (see step P33 in the figure), acid cleaning is performed. This is performed by setting the basket for cleaning in the acid cleaning device 105 and operating the acid cleaning device 105 (see step P34 in the figure). Then, when the acid cleaning is completed, soft water cleaning is performed in the second sink 104 (see step P35 in the same figure). And
In the drying basket 106, the reinforcing material that has been subjected to the acid cleaning is transferred from the cleaning basket to the drying basket (Step P36 in FIG. 3), and the drying basket is transferred to the cleaning drying apparatus 10.
7 (see step P37 in the figure). When the drying of the reinforcing material is completed, the reinforcing material in the basket for drying is transferred to the net pad in the cooling stand 108, and the net pad is cooled by the cooling stand 1.
08 to cool the reinforcing material (step P3 in FIG.
8). After that, the reinforcing material is accommodated in a car for bonding processing, and bonding processing is performed in the bonding processing apparatus 109 (see step P39 in the figure). When the bonding process is completed, the reinforcing material is transferred from the bonding basket to the drying basket again, and the drying basket is set in the bonding drying apparatus 110, and hot air drying is performed. (See step P310 in the figure).
Then, after the drying is completed, the reinforcing material is transferred to the net pad again on the second work table 111 (see step P311 in the same figure) and set in the baking oven 112 (see step P312 in the same figure). The reinforcing material that has been baked in the baking oven 112 is supplied to the third workbench 113.
Then, it is transferred to an aluminum pad (see step P313 in the same figure), and this reinforcing material is stored in the desiccator 114 (see step P314 in the same figure).

As described above, each process is performed by a single processing device, and the operator transfers the reinforcing material to a different car and transports the reinforcing material to each processing device to perform each processing. . Therefore, there is an inconvenience that the operation becomes complicated. Further, since it is necessary to transfer the reinforcing material to a different car, for example, when simultaneously processing a plurality of types of reinforcing materials, the reinforcing material may remain in the cleaning basket. As a result, different types of reinforcing materials may be mixed.

In each of the above-mentioned processing steps, a processing time is set, and this time is managed by one timer in the apparatus.

However, since the transfer between the processing steps is performed by an operator, the time required for the transfer varies, so that the time set in each processing apparatus varies. As a result, there is an inconvenience that there is a possibility that the processing time for each work varies, and the quality varies.

The present invention has been made in view of such circumstances, and an object of the present invention is to simplify the work in the step of cleaning and bonding a block reinforcing material for a dry-type continuously variable transmission. Another object of the present invention is to surely prevent the mixture of different types of reinforcing materials, and also to prevent a variation in processing for each work.

[0012]

In order to achieve the above object, the present inventor aims at automating a series of operations in a cleaning and bonding process, and improves a car containing a reinforcing member and a baking apparatus. The present invention has been completed by making improvements and other improvements.

More specifically, the present invention provides a method of cleaning and bonding a reinforcing material of a resin block of a dry-type continuously variable transmission in which a number of blocks are juxtaposed at a predetermined pitch over an entire length of a belt in an endless tension band. Assuming an automatic cleaning and adhesion processing device for a resin block reinforcing material for a dry-type continuously variable transmission that performs processing, an alkali cleaning device for performing alkali cleaning of the reinforcing material, a soft water cleaning device for cleaning the reinforcing material with soft water, An acid cleaning device for performing acid cleaning of the reinforcing material, a drying device for drying the reinforcing material, a cooling device for cooling the reinforcing material, an adhesive processing device for performing the bonding process on the reinforcing material, and a baking process for baking the reinforcing material after the bonding process. A line in which the devices are arranged in order, and the line is configured to be movable along this line, and the plurality of reinforcing members are so arranged that the processing of each device is sequentially performed on the plurality of reinforcing members. There the contained accommodated cage and that a loader for conveying sequentially to each device.

[0014] Then, the above-described printing apparatus is
And a slope arranged so as to traverse the
After passing through a roughly cylindrical storage basket rolling on a rope for a predetermined time,
One piece feed to discharge one piece after the outside of the above baking device
And a mechanism having a mechanism .

In this case, the loader sequentially sets the storage car in each of the above-described devices, and each of the devices sequentially performs the respective steps, thereby performing the cleaning and bonding processing of the reinforcing material. For this reason, conventionally, the transport of the car performed by the worker is omitted, and the work is simplified.

Further, since all the processes from alkali washing to baking are performed in the same storage basket, the transfer of the reinforcing material is omitted, and the operation is simplified. In addition, since there is no transfer of the car, mixing of different types of reinforcing materials is reliably prevented.

Further, when the storage car is set on the upper part of the slope of the printing apparatus, the storage car rolls and automatically passes through the printing apparatus, thereby performing the printing process. At this time, the storage basket is kept in the baking device for a predetermined time by the one-piece feeding mechanism, and the baking process is reliably performed for the predetermined time.

In such a printing apparatus, it is preferable from the viewpoint of production efficiency that a plurality of storage baskets sequentially flowing in a line be stored in the apparatus and the printing processing be performed simultaneously.

Therefore, as described in the second aspect , the baking device is configured to house a plurality of storage cars therein, and the number of timers corresponding to the plurality of storage cars is provided. Then, each timer may measure the processing time for each of the storage cars and control the one-piece feeding mechanism. In this case, each timer counts the processing time for each storage car, so that even if the time at which the storage car is put into the printing apparatus varies due to intermittent flow through the line, the time of the printing processing itself does not change. Can be reliably prevented from being varied.

As the "single feed mechanism", for example, in the case where no slope is provided, a conveyor may be arranged in the printing apparatus so as to transport the storage basket. On the other hand, when providing a slope,
A pair of cylinders having rods protruding on the slope surface may be arranged side by side along the slope, and a single feed mechanism may be configured by controlling the pair of cylinders. That is, if the rod of the front cylinder is retracted with the rod of the rear cylinder protruding, the first storage car rolls on the slope and is discharged out of the printing apparatus, while By engaging the storage cage with the rod of the rear cylinder, it is possible to prevent the storage cage from following the front storage cage and coming out of the printing apparatus. In this way, a single feed mechanism of the storage basket is realized.

Further, the one-piece feed mechanism is provided with, for example, a substantially L-shaped stopper member, and the stopper member is disposed horizontally so as to be rotatable about its substantially central position. One end and the other end of the stopper member may alternately project on the slope surface.

In this case, when one end of the stopper protrudes, the leading storage car is locked with the one end to prevent its rolling. On the other hand, when this stopper member is rotated, the one end of the stopper is rotated. Is retracted from the slope surface, so that the leading storage car rolls on the slope surface and moves. On the other hand, since the other end of the stopper member projects on the slope surface, the second storage car is engaged with the other end, and the rolling of the second storage car is prevented. When the stopper member is rotated in the opposite direction to the above, the other end of the stopper member retracts from the slope surface, and the second storage car rolls. Since it protrudes upward, it engages with this one end and its rolling is prevented. In this way, the storage baskets are sent one by one. When such a stopper member is used, only one control device needs to be used, so that the number of parts can be reduced and the cost can be reduced.

[0023]

As described above, according to the apparatus for automatically cleaning and bonding a resin block reinforcing material for a dry-type continuously variable transmission according to the present invention, the cleaning and bonding process is automated, and the work is greatly simplified. Can be. In addition, it is possible to prevent the dispersion of the processing and to surely prevent the mixing of different kinds of reinforcing materials.

The first storage basket is discharged by operating the member 41a. This discharge is detected by the photoelectric tube 38c. When the first storage car is in the oven 38, the second storage car is loaded, and the processing time of the second storage car is counted by the second timer. In this way,
The first to fifth storage baskets are baked in the oven 38 and discharged after a predetermined processing time has elapsed, so that the time of the baking processing is managed. The sixth storage car is measured by the first timer. Thus, for example, in the case where only one timer is provided, if there is a variation in the loading time of the storage car, the processing time will vary. By providing a timer, even if the input time fluctuates (t in FIG.
1 to t4), it is possible to avoid the occurrence of variations in the processing time (see tc in the figure).
