[Detailed Description of the Invention] <Industrial Application Field> The present invention is a storage book by arranging and transporting a plurality of plate-shaped materials, especially tires), which are continuously transported on an incoming conveyor line. This relates to a fully automatically operated transfer device that loads onto the shelves of a trolley.

<Prior Art> Generally, a tire tread is continuously extruded as a band-like body having a predetermined cross section by a rubber extruder, and then cut into regular size pieces and sequentially loaded onto a storage book cart for storage.

Conventionally, in this type of tire tread extrusion process, at the end of the conveyor line of a continuously operating extruder, two alignment conveyors are installed in parallel in a substantially perpendicular direction in contact with the side surface of this conveyor. Elevating means each having a tire tread storage book cart mounted at the end thereof are provided, and the tire treads sent from the alignment conveyor L are loaded onto the tire tread storage book cart on one elevating means, while the tire treads are loaded onto the tire tread storage book cart on the other elevating means. An empty truck is prepared, and when the tire tread storage book truck being loaded is full, loading is switched to the other prepared empty truck, and this operation is repeated to ensure continuous operation of the extrusion device. A method was used to

<Problems to be Solved by the Invention> However, in the above conventional method, it is not only necessary to provide two sets of loading devices on the side of the conveyor line of the extruder, but also two sets of alignment conveyors, elevating means, etc. are also required. This resulted in an increase in factory floor space and equipment costs. In addition, the loading and unloading of the trolley is naturally complicated in two directions, and the switching control of the loading device is also complicated, resulting in a disadvantage that work efficiency cannot be improved.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to use a compact configuration using an m-loading device, which makes it possible to utilize floor space without wasting it, to reduce equipment costs, and to automatically and efficiently load tire treads onto the shelves of a storage book cart. The purpose of the present invention is to provide a transfer device that can be loaded with

<Means for solving the problems> In order to achieve the purpose described above, the configuration of the transfer device of the present invention is as follows:
A first branching conveyor that changes the transfer direction of the plate-shaped materials at right angles, and a plurality of plate-shaped materials to be transferred are arranged in front of the first branching conveyor, and after the alignment,
An alignment and second branching conveyor that changes the direction of transfer of the plate-shaped material at right angles, a roller conveyor that can transfer the plate-shaped material forward in the direction of the third branching conveyor and keep it there for a certain period of time, and from the roller conveyor. a third branch conveyor that changes the direction of transfer of the plate-shaped material being sent at right angles;
The present invention is characterized by comprising at least one stock conveyor that can be stopped, and a loading conveyor that loads plate-shaped materials transferred from the stock conveyor onto a shelf at a predetermined position.

<Function> The plate-shaped materials are sequentially carried onto the first branch conveyor by the existing carry-in conveyor line that operates constantly at a constant speed, and the transfer direction is transferred by the first branch conveyor that operates intermittently in synchronization with this. It is changed to a right angle and sent onto the alignment and second branching conveyor. When the alignment and second branching conveyor lines up a predetermined number of plate-shaped materials, if there is no plate-shaped material on the front roller conveyor, the conveying direction of the aligned plate-shaped materials is changed to a right angle and the plate-shaped materials are transferred to the third branch. While being sent toward the conveyor, if there are plate-shaped materials, the aligned plate-shaped materials are stopped.

The aligned plate-shaped material fed onto the third branch conveyor is now changed in direction of transport at right angles and fed onto at least 61 stock conveyors.

Next, this stock conveyor sends the aligned plate-like materials onto the loading conveyor when there is no plate-like material on the loading conveyor in front, while stopping the aligned plate-like materials when there is plate-like material. . And the loading conveyor is
The aligned plate materials that are sent are loaded onto the shelves of the book cart at predetermined positions one after another without delay, and when all the shelves are loaded, the fully loaded cart is sent to the discharge line, and the empty cart is replaced instead. During the time until the delivery of the treads is completed, that is, the changeover time (truck change time), the plurality of treads that are sent in sequentially from the delivery conveyor line are arranged into multiple sets of a predetermined number of treads, and are mainly stocked. They are stopped one after another on the conveyor, and a set-up time is provided on the conveyor.

(d) Furthermore, the third and fourth treads are carried in from the carry-in roller conveyor C, and by repeating the same operations as in (a), (b), and (c) above, the third and fourth treads are transferred to the second treads on the second branch chain conveyor 4. The first tread is located at the position of the phototube position sensor S4, the second tread is located at the position of the phototube position sensor S4, and the second tread is located at the position of the phototube position sensor S4. Third. Four fourth treads are arranged rearward in sequence at equal intervals. The phototube position sensor S4, which has detected the first tread, rotates the motor M7, and by the action of the eccentric link 64°, the second branch chain conveyor 4 is immersed below the roller conveyor 5, and the four aligned treads are moved by the rollers. Transferred onto the conveyor 5, the transport direction is changed to right angles.

(e) Next, the roller conveyor 5 is rotationally driven via a series of sprockets 71, and the four treads are sent forward in the direction of the third branch conveyor 6 as shown by the arrow. The phototube position sensor S5 detects the tread that has been sent 7,
The drive motor of the roller conveyor 5 is stopped, and the motor M7 is
is rotated in the opposite direction to cause the second branch chain conveyor 4 to protrude again above the roller conveyor 5, and motor M6 (see Figure 5.6)
is rotated to cause the third branch chain conveyor 6 to protrude from the upper surface of the roller conveyor 5 via the eccentric link 64.

In this way, the four treads are transferred onto the third branch chain conveyor 6, and the transfer direction is again changed to a right angle as indicated by the arrow in FIG.

(f) The motor M5 and the motor M4 are driven to rotate, the four trail lads are sent to the stock chain conveyor 7 in front, and the first tread reaches the phototube position sensor S6.

At this time, the phototube position sensor S6 detecting the first tread stops the motor M5 and rotates the motor M6 in the reverse direction to stop the third branch chain conveyor 6 and cause the roller conveyor 5 to retract below. . At the same time, the phototube position sensor S6 works in conjunction with the phototube position sensor S7 that detects the presence or absence of a tread on the stock chain conveyor 8, and if there is a tread on the stock chain conveyor 8, the motor M4 is stopped and the stock chain conveyor is moved. On the other hand, if there is no tread, motor M4 continues to rotate and motor M
3 is rotated to run the stock chain conveyor 7.8 at a constant speed, and the four treads are transferred to the stock chain conveyor 8.

(g) The phototube position sensor S7 that detects the first tread is linked with the phototube position sensor S8 that detects the presence or absence of the tread on the loading chain conveyor 9, and when there is a tread on the loading chain conveyor 9, the phototube position sensor S7 detects the first tread. Motor M
3 and the above motor M4 are stopped to stop the running of the stock chain conveyor 7.8. On the other hand, if there is no tread, the motor M3 continues to rotate and the motor M4 is stopped.
2 (see Fig. 4 (a)) to make the stock chain conveyor 8 and the loading chain conveyor 9 run at a constant speed, and the four treads move onto the loading chain conveyor 9 as shown by the arrows in Fig. 1. be transferred. When the phototube position sensor S8 at the tip of the conveyor detects the first tread that has been sent, it stops the motors M2 and M3 to stop the loading chain conveyor 9 and the stock chain conveyor 8, and also stops the loading chain conveyor from moving. base 13
A drive signal is sent to the table lifter 12 that raises and lowers the table. At this time, the storage book trolley should be loaded with treads! 0 shelf 32 is lowered to a horizontal position and held by a shelf lowering device 21 (see FIG. 9), as will be described later.

(h) When the table lifter 12 is operated by the above drive signal, the loading chain conveyor 9 is raised by the thickness of one shelf, and the loading chain conveyor 9 is always placed on the base 13.
The upper surface of the loading chain conveyor 9, which is in the positional relationship shown by the two-dot chain line in FIG. 9 with the tip (24), is located slightly above the held shelves as shown.

(S) Next, the motor M+ rotates, and the moving frame +5 connected to the chain 36 moves over the fixed frame t4 to the fourth position.
The movable frame 15 moves from the stock chain conveyor contact position at the rear end indicated by the two-dot chain line in the figure to the loading position at the rear end shown in the figure.
40) enters the vicinity of the pivot point of the shelf 32 on the storage book cart.

When the moving frame 15 moves forward, the motor M2 rotates and the chain 50 rotates, but since the cam clutch 45 provided on the driving sprocket 44 is disengaged, the rotation of the chain 50 is caused by the rotating shaft 42. The loading chain conveyor 9 is stopped.

(N) Next, the motor Ml rotates in the reverse direction, and the moving frame 15
Since the setting is made so that the backward speed of the loading chain conveyor 9 and the running speed of the loading chain conveyor 9 are approximately equal, the four treads lined up on the loading chain conveyor 9 are transferred directly onto the shelf 32 in order starting from the first tread. It will be done.

(l) f When the hyperactive frame 15 retreats to the stock chain conveyor contact position, motors Ml and M2 stop,
The cam clutch 45 is disengaged, and the loading of the four treads onto the shelf 32 is completed. The shelf unloading device 21 lowers and holds the next empty shelf to a horizontal position, as will be described later.
.

(w) By repeating the operations (a) to (l) above, the treads that are carried in one by one from the carry-in roller conveyor C are arranged in groups of four and sequentially loaded onto the six shelves of the storage book cart 10. , loading to Zenshu is completed.

(W) The storage book cart 10 fully loaded with treads is moved on the rail 30 to the discharge position by the chain conveyor 29 installed on the pedestal 26 under the floor at the loading position A (see Figure 1.2), and then moved to the discharge position. An empty truck is similarly carried in as shown by the arrow in the figure, and is positioned at the loading position by the stop positioning device 31.31. Meanwhile, the table lifter 12 operates and the base! 3 is lowered, and the loading chain conveyor 9 is lowered to the horizontal holding position of the lowest shelf.

The time from the completion of loading all shelves to the start of loading to the next empty cart, that is, the changeover time, is, for example, 1 minute, and the loading roller conveyor C carries in treads at a frequency of 122 treads.

Among the conveyors shown in FIG. 1, the entrance roller conveyor 1. 1st branch chain conveyor 2. Auxiliary alignment chain conveyor 3. The alignment/second branching chain conveyor 4 operates at an optimal speed and cycle corresponding to the frequency of the treads being brought in, so that four treads are aligned on the alignment/second branching chain conveyor 4 every 20 seconds. 5. Roller conveyor The operating cycle of the first branch chain conveyor 2 and the stock chain conveyor 7.8 is about 1/4 of the 20 seconds it takes to bring in four treads, and the running speed is about 4 times faster, and the remaining time is the waiting time. The four treads arranged on the second branch chain conveyor 4 complete their arrangement on the stock chain conveyor 8 after 20 seconds.

Each operation time of the loading chain conveyor 9 is, for example, 5 seconds for tread delivery from the stock chain conveyor 8;
It takes 5 seconds to move to Moehata, 10 seconds to load the tread onto the storage book cart and retreat, and 20 seconds in synchronization with the tread loading frequency.
Operates on a cycle of seconds. Therefore, at the beginning of the above step change time,
Four treads are lined up on the stock chain conveyor 8, the conveyor behind it is empty, and the next four treads have been lined up on the second branch chain conveyor 4. After 20 seconds from this state, the loading chain conveyor 9 and the stock chain conveyor 8 which are in contact with each other, the stock chain conveyor 7 after another 20 seconds, and the third branch chain conveyor 6 in the final 20 seconds, the four treads are I will keep stocking up. Then, when the changeover time is over, loading of treads starts again from the lowest shelf of the new empty truck in the same manner as described above.

Next, the operation of the shelf unloading device 21 (see FIG. 9) will be described.

(I) From the chain conveyor 9 to the shelf 32 in the above (N)
When loading of the four treads is completed, the main body 83 of the shelving device 21 is raised by the retraction of the rod of the air cylinder 23, and the movable plate 84 inserted into the main body 83 is moved forward by the protrusion of the rod of the air cylinder 85. However, the hook support fitting 92 at the tip of the link 86a attached to the movable plate 84 moves along the two-dot chain line (G→H→I-J) in the figure due to the rod retraction of the air cylinder 91 and the movement of each rod. exercise like.

The air cylinder 94 below the hook support fitting 92 at position J
The rod 94a that always projects comes into contact with the hook bin 32a at the tip of the shelf 32 under the guidance of a contact plate 95.

(°) When the rod 94a comes into contact with the hook pin 32a and the spring 96 is pushed down, the rod 93a of the upper air cylinder 93 protrudes due to the action of the proximity switch, and the upper and lower rods 93a and 94a sandwich the hook pin 32a and put it on the shelf. 3
Hold 2. At this time, the support arm 101 of the shelf support device 98, which had been supporting the shelf 32 from below, rotates downward due to the retraction of the rod of the air cylinder 102 and stands by.

(c') The rod of the air cylinder 23 protrudes and the main body 83
is lowered, the rod of the air cylinder 91 protrudes approximately 80%, and the hook support fitting 92 grips the shelf 32 and descends to position K, drawing an inner plate as shown by the broken line in the figure. At this time, the arm 99 of the shelf holding device 97 rotates downward due to the protrusion of the loft of the air cylinder +00, and presses the shelf 32 at position K to the upper surface (position) of the cart, and also presses the upper side of the hook support fitting 92. The rod 93a of the air cylinder 93 retracts, the air cylinder 85a retracts, the air cylinder 91 protrudes 00%, and the hook support fitting 92 retreats to position G. Meanwhile, the above support arm 1 was waiting.
01 is rotated upward again by the cylinder 102 and supports the stacked empty shelves from below.

In this way, the operations after (l) described above continue, and the shelving device 21 and the like repeat the operations (a), (b), and (b) described above every time a set of four treads is loaded.

In the above embodiment, the table lifter 12 is not provided under the storage book cart 10 but is provided under the loading chain conveyor 9, so that the cart replacement time, that is, the changeover time can be shortened. In addition, since the plurality of treads that are successively carried in from the carry-in roller conveyor C during the stage change time are mainly stocked sequentially on the stock chain conveyors 7 and 8 and the loading chain conveyor 9, during the stage change time, Tread loading can be carried out efficiently using a single loading device without stopping the extrusion line, and it is also possible to load the tread efficiently without stopping the extrusion line. The installation area can be reduced to about 2/2,
Furthermore, since the floor space around the carry-in roller conveyor line, which was previously wasted, is utilized, it can contribute to the efficient use of factory floor space. Furthermore, a shelf unloading device 21 and a shelf support and shelf holding device 97 that assist loading. '98,
The stock chain conveyors 7 and 8 are housed compactly in a frame 24 that moves up and down while rotating as the table lifter 12 goes up and down, the loading chain conveyor 9 has excellent mobility, and the loading work efficiency is significantly improved. Furthermore, equipment costs can also be reduced due to the above-mentioned reduction in installation area and compact arrangement of each device.

In the above example, tire treads were stocked using three conveyors during the changeover time, but the number of stock conveyors and their arrangement can be appropriately determined depending on the changeover time and the frequency of tread delivery. . Further, the number of treads to be aligned is determined according to the tread width, and by appropriately arranging phototube position sensors, three or five treads can be aligned.

It is also possible to move the table lifter up and down and move the movable frame 15 back and forth by cylinder drive.
