[0013]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2, the tire loading device 1 is roughly divided into a sorting mechanism D for performing a sorting step of sorting raw tires (conveyed objects) 2 having different sizes by size while transporting the tires in a flat posture, and a standing posture from the flat posture. A posture changing mechanism A for performing a posture changing step of changing the posture, a skewering mechanism B for performing a skewing step for sequentially skewing the raw tires 2 whose posture has been changed, and the skewering raw tire 2 is bucketed by the skewering mechanism B. A bucket device C having the bucket C2 for performing a transfer step of transferring the raw tires 2 at a time to the C2, and an unloading cart E used for a reloading step of transferring the raw tires 2 from the bucket C2 at once. I have.
[0014]
2 and 3, the sorting mechanism D includes a multi-type transport unit D1 for transporting raw tires 2 of various sizes and widths formed by the tire molding apparatus 3, and a raw tire by size from the multi-type transport unit D1. And a sorting / conveying means D3 disposed corresponding to the separating means D2 and conveying the raw tires 2 of different sizes taken out by the separating means D2 to the attitude changing mechanism A. I have.
In order to optimize the layout of the equipment in the factory, the multi-species conveying means D1 includes one or more lifters D4, a first horizontal conveying conveyor D5, a traverser D6, a second horizontal conveying conveyor D7, and the like in FIG. The raw tire 2 formed by the lower or upper tire forming apparatus 3 is lifted and lowered by a lifter D4 and supplied to a second horizontal transfer conveyor D7 via a first horizontal transfer conveyor D5 and a traverser D6, and from the lifter D4. It is directly supplied to the second horizontal transport conveyor D7.
[0015]
Raw tires 2 of various sizes, widths, and the like are conveyed in a mixed state on the second horizontal conveying conveyor D7, and the raw tires 2 can be conveyed in a prone posture in which the axis is in the vertical direction.
FIG. 4 shows the lifter D4. The lifter roller D4a is inclined downward so that the raw tire 2 slides down onto the first or second horizontal transport conveyor D5 or D7. The lifter roller D4a uses a Teflon (R) coating roller in order to prevent a race cover or the like from coming into intimate contact with the roller to prevent slippage.
[0016]
A plurality of sorting means D2 are arranged at positions overlapping with the second horizontal transport conveyor D7, detecting means (not shown) for detecting the size of the raw tire 2 on the second horizontal transport conveyor D7, And a tilting means D9 for lifting and inclining one side of the sorting member D8 to lift and tilt the one side of the sorting member D8, and the size of the raw tire 2 transported on the second horizontal transport conveyor D7. Is detected by the detecting means, and when the raw tire 2 of the size in charge of the sorting means D2 is detected, the tilting means D9 is operated to lift one side of the sorting member D8, and only the raw tire 2 of that size is sorted. Send it out to the transport means D3.
[0017]
The sorting / transporting means D3 is prepared for each size. Raw tires 2 of the same size are placed on each sorting / transporting means D3, stored, and sequentially transported to the posture changing mechanism A.
A posture changing mechanism A is arranged downstream of the sorting and conveying means D3 of each size. The attitude changing mechanism A is configured so that a tire turning tool A2 supported on a frame A1 common to the sorting and conveying means D3 via a pivot shaft A5 can be turned by about 90 degrees by an actuator A3.
[0018]
The tire rotating tool A2 supports a corner portion of a substantially L-shaped rotating frame A4 in a side view on a pivot shaft A5, and provides a free bearer A6 on a long side A4a of the rotating frame A4, and a short side A4. To accept the raw tire 2.
The tire rotating tool A2 places the raw tire 2 carried in from the sorting and conveying means D3 on a free bearer A6 with the pivot shaft A5 side slightly downward, and wraps the outer periphery of the raw tire 2 on the short side of the rotating frame A4. In this state, the actuator A3 is actuated to raise the long side A4a, and the raw tire 2 is received at the short side A4b (posture changing step).
[0019]
As a result, the raw tire 2 that has been transported on the sorting and transporting means D3 in the prone attitude is changed to the upright attitude in which the axis thereof is substantially horizontal by the tire turning tool A2.
The posture changing mechanism A is a set of two units, one bucket device C is disposed at an intermediate position, a skew insertion mechanism B is disposed in front of each posture changing mechanism A, and one set of two units is provided. The skewering mechanism B is disposed on the common rail device 4 so as to be movable in the left-right direction, and is movable to a central position facing the bucket device C.
1, 2, 5 to 10, the skewering mechanism B is configured to receive the skewers B1 by inserting the skewers B1 into the raw tire 2 in the standing posture on the posture changing mechanism A, and the base end of one or more skewers B1. Skew table B2 that cantileverly supports the skew part, support pedestal B3 that movably supports skew table B2 in opposition to the attitude change mechanism A, and supports this support pedestal B3 up and down via elevating means B4. And a base carriage B5 that is movable in the direction of intersection (at right angles) with the skew table B2.
[0020]
The skewers B1 are formed of a pipe or a round bar material, and may be one. However, in the embodiment, two skewers B1 are provided in parallel so as not to swing, and each skewer B1 has a low frictional resistance. In order to make the movement of the raw tire 2 smooth, a tack-free coating is applied to the outer peripheral surface thereof. Further, the height of the skewers B1 from the skewer table B2 is such that the raw tires 2 of the maximum size can be skewed and suspended.
The insert skewer B1 is detachably supported by the skew table B2, and is supported so as to be capable of adjusting the position in the longitudinal direction. Therefore, even if the raw tire 2 has a wide width, the raw tire 2 can be closely skewed and held, and the narrow raw tire 2 can be skewed more than the wide one.
[0021]
A skewer B2 supporting the skewer B1 is slidably mounted on the stool B3, and is driven by a motor provided on the stake B3 and a driving means B6 such as a screw shaft or a cylinder. Moved in the direction.
The kushidai B2 has a relatively short moving distance when taking the raw tire 2 from the attitude changing mechanism A, but when transferring the raw tire 2 to the bucket device C, it is shown by a two-dot chain line in FIG. It moves greatly to the protruding position.
Each base truck B5 has wheels and is movable on a rail 4a of the rail device 4, and an operating means 4b such as a hydraulic cylinder of the rail device 4 is connected thereto. The end 4a can be moved from a position facing the posture changing mechanism A to a position facing the bucket device C at the center in the longitudinal direction.
[0022]
When the rotating frame A4 of the posture changing mechanism A has the raw tire 2 in the upright posture, the skew insertion mechanism B advances the retracted skew B1 forward and inserts it into the hole of the raw tire 2. The skewers B1 in which the raw tires 2 are skewed are raised by the elevating means B4 to lift the raw tires 2 from the rotating frame A4, and then retreat and descend to the skewering height.
This operation is performed every time the posture changing mechanism A changes the posture of the raw tire 2, and the skewers B1 skew the raw tires 2 so that the raw tires 2 previously skewed are placed on the base side of the skewers B1. Pushing is performed until the required number of raw tires 2 are held on the skewers B1.
[0023]
This operation is performed in the same manner regardless of whether the width of the raw tire 2 is large or small. About 10 pieces of the wide raw tire 2 and about 12 to 16 pieces of the narrow green tire 2 are placed on the skewers B1. The raw tires 2 suspended and skewed are brought into close contact with each other, whereby the raw tires 2 are aligned in parallel with each other (skipping step).
The skewering mechanism B holding the required number of green tires 2 is moved to a position facing the bucket device C by the operating means 4b, and the skew tables B2 and the skewers B1 are protruded and moved via the driving means B6 to thereby produce the raw tires. 2 is transferred to the bucket device C, and thereafter, the insertion skewer B1 is retracted and removed from the raw tire 2 (transferring step).
[0024]
In order to improve the transfer of the raw tire 2 from the posture changing mechanism A to the skewering mechanism B, the length of the short side A4b of the rotating frame A4, the length of the skewering B1, etc. are set appropriately. Is preferred.
In FIGS. 1, 2, 11 to 14, the bucket device C includes a bucket base C <b> 1, a large number of raw tires 2 superposed on the bucket base C <b> 1 and concentrically arranged and rotated to rotate the raw tire 2. It has a bucket C2 that can be released at once, and a work clamp means C3 that, in combination with the bucket C2, clamps a number of raw tires 2.
[0025]
The bucket base C1 is a stationary type, but may be configured as a bogie with wheels attached thereto. The bucket base C1 has an upper base C6 via an elevating means C5, and the upper base C6 via a swing support mechanism C7. The bucket C2 and the work clamp means C3 are mounted.
The swing support mechanism C7 swingably supports the bucket C2 on the upper base C6 via a horizontal swing shaft C8, and is formed by an actuator such as a hydraulic cylinder provided between the upper base C6 and the bucket C2. By operating the tilting means C9, the bucket C2 can be tilted leftward or rightward from the center position above the swing axis C8 shown in FIG.
[0026]
In the bucket C2, a pair of holding members CR and CL in the longitudinal direction are arranged on the substrate C10, and the holding members CR and CL collectively hold a large number of raw tires 2 transferred from the skewering mechanism B. .
Of the pair of holding members CR, CL, the holding member CL is fixed or position adjustable with respect to the substrate C10, the other holding member CR is movable with respect to the substrate C10, and a part of the work clamping means C3. Is composed.
That is, the work clamping means C3 slidably supports the clamp moving plate C11 on which the other clamping member CR is mounted on the substrate C10, and a motor and a screw shaft or a hydraulic cylinder for moving the clamp moving plate C11 on the substrate C10. And a plurality of raw tires 2 mounted on the bucket C2 can be held by moving the holding member CR to the holding member CF side via the driving means C12. I have.
[0027]
The pair of holding members CR and CL are provided with a free bear C4 on the raw tire 2 holding surface side, and a tack-free coating is applied to a raw tire contact surface of the bucket C2. The tack-free coating reduces the sliding resistance of the raw tire 2 with respect to the bucket C2, so that the raw tire 2 can enter and exit the bucket C2 smoothly.
Of the pair of holding members CR, CL, at least a holding member (for example, a holding member CL on the fixed side) located on the side of the skew insertion mechanism B has a concave portion CLa having an upward open shape so that the insertion skewers B1 can be fitted. Is formed.
[0028]
Therefore, the skew table B2 of the skew insertion mechanism B is moved to the position shown by the two-dot line in FIG. 7 via the driving means B6, and the large number of raw tires 2 suspended on the skew insertion B1 are carried above the bucket C2. Then, from this state, the driving means C12 of the work clamping means C3 is operated by lowering through the elevating means B4 of the skewer mechanism B and transferring the raw tire 2 to the bucket C2 while leaving the raw tire 2 in the bucket C2. The raw tire 2 is held by the pair of holding members CR and CF by moving the clamp moving plate C11.
Thereby, in the bucket C2, a large number of raw tires 2 can be stacked and stored without leaving an interval, and the raw tires 2 are clamped so as not to be separated, and then the driving means B6 of the skewering mechanism B is reversely driven. Then, the stick B1 is extracted from the raw tire 2.
[0029]
When the raw tire 2 is transferred from the skewering mechanism B to the bucket device C, the skew table B2 is raised and lowered via the driving means B6. However, the upper table C6 and the bucket C2 are raised and lowered via the lifting means C5. You may make it.
The bucket device C on which the raw tires 2 are transferred operates the tilting means C9 of the rocking support mechanism C7 to rock the bucket C2 back and forth by 45 degrees via the rocking shaft C8, and the raw tires in the bucket C2 are rotated. The raw tire 2 is released at a stroke by releasing the work clamping means C3, and is transferred to the unloading vehicle E for reloading (reloading step).
[0030]
The carry-out cart E has a structure in which an upper frame E3 is mounted on a lower frame E2 having wheels, and the lower frame E2 and the upper frame E3 can mount the raw tires 2 on the upper and lower stages. A loading guide means E1 is provided at the end of the raw tire 2 in the axial direction of E3.
The guide means E1 is formed by bending a bar into a U-shape in a front view and fixing both ends of the bar to the upper surface of the end of the upper frame E3. It prevents the loaded raw tire 2 from falling down.
[0031]
The operation of supplying the raw tires 2 of the bucket device C to the unloading vehicle E is such that, when the raw tires 2 are transferred to the upper frame E3, the bucket C2 is raised via the lifting / lowering means C5 and arranged above the unloading vehicle E; The bucket C2 is tilted and put into the upper frame E3 so as to roll down. At this time, the guide means E1 guides the rolling of the raw tire 2.
When the raw tires 2 are transferred to the lower frame E2, the bucket C2 is lowered via the lifting / lowering means C5 and arranged on the side of the carry-out carriage E, and the bucket C2 is tilted and rolled down in the lower frame E2. Put in. At this time, the leg E3a of the upper frame E3 serves as a guide means to guide the rolling of the raw tire 2 down.
[0032]
In both the upper frame E3 and the lower frame E2, the raw tire 2 in the bucket C2 is held by the work clamping means C3 until the bucket C2 is tilted, so that the reloading operation can be performed reliably and smoothly. Is
Next, a tire loading method automatically performed by the tire loading device 1 having the above configuration will be described.
Raw tires 2 having different sizes and widths formed by the tire forming apparatus 3 are sent to one or more lifters D4 or other means to the various transporting means D1 of the sorting mechanism D, and separated by the tire size detecting means. The size is detected one by one on the means D2, and if the size is set by the sorting means D2, the sorting member D8 is tilted via the tilting means D9 and sent out to the sorting / transporting means D3, and the other size is set. The raw tire 2 is supplied to the posture changing mechanism A separately (sorting step).
[0033]
When the sensor detects that the raw tire 2 has been supplied from the sorting / conveying means D3 into the tire rotating tool A2 of the attitude changing mechanism A, the actuator A3 operates to rotate the tire rotating tool A2 by approximately 90 degrees, The posture of the raw tire 2 transported in the lying posture is changed to the standing posture.
The driving means B6 of the skew insertion mechanism B is operated at the same time as or before and after the raw tire 2 is brought to the standing posture to advance the insertion skew B1 and inserted into the hole of the raw tire 2 in the standing posture. The insert B1 is raised in a state of being inserted into the raw tire 2 hole, receives the raw tire 2 from the posture changing mechanism A, retreats while the raw tire 2 is suspended, and moves the next raw tire 2 by the posture changing mechanism A. Wait for the posture change to be completed.
[0034]
When the required number of raw tires 2 are picked up on the skewers B1, the skewering mechanism B is moved left and right on the rail device 4, and the skewers B1 are opposed to the bucket device C. The driving means B6 of the skewing mechanism B is operated to move the skewer B1 to above the bucket C2 of the bucket device C, and to face the multiple raw tires 2 suspended on the skewer B1 to the bucket C2, The means B4 is actuated to lower the insert B1, and the raw tires 2 are collectively transferred to the bucket C2. In this state, the driving means B6 is operated in reverse to remove the insert B1 from the raw tire 2 in the bucket C2. .
[0035]
The work clamp means C3, which has been in the open state, is operated to close the raw skewer B1 at or before or after the insertion of the insert skew B1, and the raw tire 2 is held and held in the bucket C2.
The carry-out cart E is carried in to the side of the bucket device C, and the height of the bucket C2 is adjusted by operating the lifting / lowering means C5 in accordance with the mounting positions of the raw tires 2 in the upper and lower stages of the carry-out cart E. Then, the tilting means C9 of the rocking support mechanism C7 is operated to tilt the bucket C2 left or right from the center position, and the work clamp means C3 is released in the tilted state, so that the raw tire 2 is released from the bucket C2. , And are collectively transferred into the unloading cart E.
[0036]
When the raw tires 2 are mounted on the upper and lower stages of the unloading cart E, the unloading cart E is moved to a place where the next process of the tire forming is processed.
In the present invention, it is best that the shape of each member and the positional relationship between front and rear, left and right, and up and down in the above embodiment are configured as shown in FIGS. However, the present invention is not limited to the above-described embodiment, and the members and the configuration can be variously modified and the combination can be changed.
For example, the tire loading device 1 can be configured by a posture changing mechanism A, a skewing mechanism B, and a bucket device C, and each mechanism can be manually operated. It is also possible to use the unloading truck E as a bucket device instead of the bucket device C, and directly transfer the raw tires 2 from the skewering mechanism B to the unloading truck E.
