Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tire transport and loading device for transporting tires to a loading truck having a plurality of rows and rows of tire suspension means and loading the tires onto the tire suspension means.

Conventionally, the work of loading tires onto transportation trolleys, for example, involves removing green tires taken out from the former of a tire secondary molding machine using O-rings, sorting them by size, and loading them onto the respective trolleys. The work of transporting and loading was done manually by workers. This work is quite hard work and inefficient, so as disclosed in Japanese Patent Application Laid-Open No. 174235/1984, a method is proposed in which the bead of the tire is grasped internally with a chuck and removed from the O-ring. is proposed. However, since three or four tires are loaded onto a truck at the same time by being hoisted up using hangers, there is a problem in that the tires are easily damaged. In addition, as mentioned above, a method has been proposed in which the tires are removed from the O-ring with a chuck and transported to the subsequent process on a conveyor or the like without using a trolley, but with this method, the tires are later separated by size. The problem was that it had to be divided into two parts, and the work was difficult.

The present invention has been made by focusing on these conventional problems, and it is possible to convey the tire with the bead lightly hooked without forcefully gripping the tire, and to transport the tire in the row (horizontal) direction and the column (horizontal) direction. By providing a device that can sort and load tires by size onto a movable loading cart equipped with a means for suspending tires arranged at predetermined intervals in the longitudinal direction, workers can load tires. It relieves the heavy labor of work, shortens the time required for loading work, and improves work efficiency.It also automatically sorts tires by size and loads them onto trolleys without damaging them, making it easier to transport them to subsequent processes. Its features include a tire holding mechanism that holds tires, and a moving mechanism that moves this tire holding mechanism and loads the held tires onto tire hanging means in multiple rows and rows of a truck. a truck moving mechanism that moves the truck in the row direction of the tire suspension means; a detection device that detects the tire being transferred from the tire holding mechanism to the suspension device and issues a signal; and a control means for counting the number of tires loaded onto each row of suspension means and operating a truck moving mechanism each time loading of tires onto each row of suspension means is completed.

The present invention will be explained below based on the drawings. 1 to 5 are diagrams showing embodiments of the present invention.
First, the structure will be explained. In FIGS. 1 and 2, reference numeral 1 denotes a known tire loading truck that is driven by a drive means (not shown) and can run on a floor surface 3 with wheels 2. This truck 1 protrudes horizontally from a mounting plate 5 erected on its base 4, and has four pieces in the row direction, that is, in the front and back direction of the truck 1;
A total of 8 wires arranged at a predetermined interval in the vertical direction of the
Arms a, b, c as means for suspending book tires,
d, e, f, g, h, each arm a,
Each of b, c...h can suspend three tires. Reference numeral 7 denotes a running rail that extends horizontally and is supported by pillars 8 erected on the floor surface 3, and a chain 9 is stretched across this rail 7 as shown in FIG. 1
Reference numeral 1 denotes a traveling device that can travel on the rail 7 by means of rollers 12. This traveling device 11 has a sprocket 13 that meshes with the chain 9,
The vehicle travels by driving this sprocket 13 with a travel motor 14 that can rotate in forward and reverse directions. A proximity switch (not shown) is installed at a predetermined position on the rail 7 to detect the position of the traveling device 11 and send a signal to a known control device (not shown) (with a built-in counter) as a control means. The traveling device 11 is provided with a guide member 15 and a post 16 that can be raised and lowered while being guided by the guide member 15. This post 16 is connected via a chain and sprocket (not shown) or a rack-and-pinion mechanism to a lifting motor 17 which is attached to the guide member 15 and can rotate in forward and reverse directions, and is driven by this motor 17 to move up and down. It's getting old. A proximity switch (not shown) is attached to the guide member 15 to detect the vertical position of the post 16 and send a signal to the control device. At the lower end of the post 16, there is a hanger 19 as a tire holding mechanism, which has a turning motor 18 that can rotate in forward and reverse directions and is driven by the motor 18 and can turn around the central axis of the post 16. A proximity switch (not shown) is installed for detecting the turning position of 19 and sending a signal to the control device. Hanger 1
9 has a protruding pawl 20 in its center for hooking and holding the bead of the tire. The pillar 8, rail 7, chain 9, traveling device 1
1. The guide member 15, post 16, lifting motor 17, and each proximity switch are assembled into a hanger 19.
It constitutes a moving mechanism 21 for moving the. On the other hand, 23 is a cart moving mechanism provided below the rail 7 at a predetermined position. As shown in detail in FIGS. 4 and 5, this trolley moving mechanism 23 is slidable along a base 24 provided on the floor 3 and a sliding guide surface 25 of this base 24. , an electromagnetic magnet 26 that attracts the truck 1 when excited;
and a linear head motor 27 attached to a base 24. The electromagnetic magnet 2
6 is connected to a linear head motor 27,
It is driven by this linear head motor 27 and slides. The electromagnetic magnet 26 and the linear head motor 27 are driven and controlled by the control device. In addition, the base 24 has a first
As shown in the figure, the photodetector 29b of the photo sensor 29
is attached, and a light emitter 29a is attached to the support 8 above the light receiver 29b. This photo sensor 29 constitutes a detection means for detecting that the green tire 30 conveyed by the hanger 19 is transferred to the arms a, b, c, . . . h of the trolley 1. A signal is emitted to the control device each time one is delivered, and the number of emitted signals is counted and integrated in a counter of the control device.

Next, the operation of the tire conveying and loading device having the above-mentioned configuration is explained by transferring the green tire 30 taken out from the former 32 of the tire secondary molding machine 31 with the O-ring 33 to the trolley 1 as shown by the imaginary line in FIG. The work of loading onto arms a, b, c...h will be explained.

The secondary molding of the tire is completed, and the O-ring 33
approaches the former 32 of the secondary forming machine 31, receives the green tire 30, holds it and returns to the resting position, and the motor 17 for raising and lowering the hanger 19, which is stopped at the standard standby position above the O-ring 33, is driven by the control device, and the post 16 is lowered. When the post 16 is lowered to a position where the claw 20 of the hanger 19 can hook the bead of the green tire 30 supported by the O-ring 33, a signal from the proximity switch detecting this causes the control device to The drive of the motor 17 is stopped. Next, the traveling motor 14 is driven by the control device, and the traveling device 11 moves to the right in FIG. 1 and stops when the hanger 19 abuts the O-ring 33. Next, when the green tire 30 supported by the O-ring 33 is released, the green tire falls and its bead part catches on the claw 20 of the hanger 19. When the green tire 30 is held on the hanger 19 in this manner, the traveling device 11 moves a short distance to the left and stops. Next, the lifting motor 17 is driven and the post 16 is raised. Post 16 is the third
When the motor 17 rises to a predetermined height as shown by the imaginary line in the figure, the control device stops the motor 17 in response to a signal from the proximity switch that detects this. next,
The traveling motor 14 is driven, and the traveling device 11 moves to the left along the rail 7 while holding the green tire 30 with the hanger 19. In the middle of this leftward movement, the control device drives the hanger turning motor 18 to turn the hanger 19 as shown by the imaginary line in FIG. When the hanger 19 turns 180 degrees, the control device stops the hanger turning motor 18 in response to a signal from the proximity switch that detects this. Traveling device 1
1 reaches a predetermined position near the trolley moving mechanism 23, the control device causes the traveling motor 14 to stop in response to a signal from a nearby switch that detects this. Next, the lifting motor 17 is driven again,
Post 16 is lowered. At this time, as shown in FIGS. 1 and 2, the truck 1 stops at a predetermined position adjacent to the truck moving mechanism 23 with arms a, b, ch...h protruding in the extending direction of the rail 7. The arms a and e of the first row are now in a position where they can receive the green tire 30 from the hanger 19. Post 16 is on the second row of trolley 1 (lower row)
When the arm e of the first row is lowered, the proximity switch detecting this sends a signal to the control device, and the lifting motor 17 is stopped. Next, the traveling motor 14 is driven, and the traveling device 11
, the green tire 30 held by the hanger 19 is transported to the innermost part of the arm e in the second row and first column of the truck 1. At this time, the arm e in the second row and first column passes through the hole in the center of the green tire 30. When the proximity switch detects that the traveling device 11 has conveyed the green tire 30 to the innermost part of the arm e, the traveling motor 14 is stopped, and the lifting motor 17 is driven to move the green tire 30 to the innermost part of the arm e.
6 (and the hanger 19 holding the green tire 30) is lowered a short distance. As a result,
The green tire 30 is transferred from the claw 20 of the hanger 19 to the arm e. This green tire 30
When the green tire 30 blocks the light emitted from the light emitter 29a of the photo sensor 29 during delivery, a signal is emitted from the light receiver 29b to the control device, and this signal is counted by a counter in the control device. When the green tire 30 is transferred to the arm e, the traveling motor 14 is driven, and the traveling device 11 moves to the right, moves away from the arm e, and stops. Then, the post 16 rises, and the traveling device 11 moves to the right again and returns to the standard standby position above the O-ring 33 and stops. During this rightward movement, the hanger 19 is rotated 180 degrees in the opposite direction, and the claw 20 returns to its initial orientation (rightward in FIG. 1). When the traveling device 11 returns to the standard standby position, the hanger 19 is lowered again, the above-described operation is repeated, and the green tire 30 is suspended from the center of the arm e in the second row and first column. When the three green tires 30 are suspended from the arm e in the second row and first column in this way, the post 16 is used to transfer the fourth to sixth green tires 30 to the arm of the trolley 1. The descending distance becomes shorter, and the green tire 30 is delivered to the arm a in the first row (upper row) and first column. When the three green tires 30 are also suspended from the arm a in the first row and first column, the electromagnetic magnet 26 of the cart moving mechanism 23 is excited by the control device to attract the cart 1. Then, the linear head motor 27 is driven, and the carriage 1 is moved by the electromagnet 2.
6, the arms a, b, c...h are moved in the row direction (forward) by a distance corresponding to the spacing between each column. As a result, the arm b of the second row of the truck 1,
f comes to a position where it can receive the green tire 30 from the hanger 19. Then, the above-described transporting and loading operation of the green tires 30 is repeated sequentially, and the trolley 1 is sent in the row direction by the predetermined distance, so that all eight arms a, b, c...h in 2 rows and 4 columns are loaded with green tires. When 30 is hung three by one,
A full signal is issued from the counter of the control device. The full truck 1 is then transferred to the next process, a new empty truck 1 is brought to the predetermined tire loading position, and the above-described operations are repeated. Note that tire size management is facilitated by loading only green tires 30 of the same size onto the same truck 1.

In the embodiment, after the hanger 19 receives the green tire 33 from the O-ring 33,
The green tire 30 was delivered to the trolley 1 by turning 180 degrees and changing direction.
Needless to say, it can be changed as appropriate depending on the relative positional relationship with 3.

As explained above, according to the present invention, tires are transported with their bead portions lightly hooked without being forcefully gripped, and each size is transferred to a loading cart having tire hanging means arranged in multiple rows and columns. Since it is possible to provide a device that can separate and load tires into different parts, workers are freed from the heavy labor of loading tires onto loading carts, the time required for loading work is shortened, and work efficiency is improved. Various effects can be obtained, such as being able to sort tires by size and loading them onto loading carts without damaging them, making transport to subsequent processes easier.
