Description

Storage box of tire component server

Technical Field

The application relates to a storage box or storage carrier applied to tire component production equipment, a tire component server or a release station.

Background

A known tire building magazine comprises a magazine roll for receiving a length of wound tire components separated by a patch layer for a plurality of turns, and a patch roll for separating the tire components from the patch layer in a known manner when supplying the tire components to a tire building drum. The magazine comprises a manually operated lifting mechanism which is movable between a discharge position, in which empty stock rolls are lowered onto the factory floor for discharge, and an operating position, in which full stock rolls are lifted from the factory floor for supply to the tyre component server. The magazine roll and/or magazine are provided with a braking mechanism to lock the magazine roll against rotation in the operating position until the magazine is docked or inserted into the receiving station of the tire component server. Thus, accidental loosening of the stock roll can be prevented.

SUMMERY OF THE UTILITY MODEL

A disadvantage of known tire building magazines is that sometimes the stock rolls need to be manually repositioned or reeled, for example, to place the stock rolls in a more appropriate location or to rewind loose rolls before accessing the receiving station of the tire component server.

However, when the stock roll is at the discharge position, the stock roll cannot be rotated freely due to direct contact with the factory floor, and when the stock roll is lifted to the operation position but is not yet docked, the brake mechanism prevents manual rotation of the stock roll.

It is an object of the present application to provide a magazine for a tire component server that provides greater flexibility in the loading and/or unloading of magazine rolls.

The present application provides a magazine for a tire component server, comprising a frame having a base for moving the frame over a support surface, the frame being open in a feeding direction for receiving a roll of material, the magazine further comprising a lifting mechanism for lifting the roll of material, the lifting mechanism comprising a support defining a roll axis for supporting the roll of material, the roll being rotatable relative to the support about the roll axis, the support being movable between a discharge position, wherein the discharge position is a position in which the roll is lowered onto the support surface for discharge, and an operating position, wherein the operating position is a position in which the roll is lifted from the support surface for supply to the tire component server, the magazine further having a braking mechanism for braking the magazine when the support is in the operating position and the magazine is not docked into the tire component server, the brake roll is rotatable about a roll axis, and the magazine includes at least one blocking element for blocking the lifting mechanism and thereby preventing movement of the carriage when the carriage is in an intermediate position between the operating position and the discharge position, wherein the carriage is arranged in the intermediate position such that the support roll is disengaged from the brake mechanism and spaced from the support surface.

In the neutral position, the roll may be rotated manually and freely when the magazine is not docked into the tire component server, for example for the purpose of relocating or rolling the magazine roll or the blanket roll. In particular, a brake mechanism for preventing rotation of the roll of material when the magazine is not docked into the tire component server may be circumvented. Also, the roll may still rotate because the roll is not fully lowered to a support surface, such as a factory floor, without direct contact with the support surface.

In a preferred embodiment, the support is arranged in a neutral position to physically isolate the roll from the braking mechanism. The braking mechanism may act, for example, by applying a frictional force to the shaft or rim of the roll. By physically isolating the roll from the braking mechanism, direct contact between the braking mechanism and the roll is interrupted, allowing rotation of the roll.

In another embodiment, the roll axis defined by the holder extends at a discharge level in the discharge position, at an operating level in the operating position and at an intermediate level between the discharge level and the operating level in the intermediate position. The intermediate height may be selected to isolate the roll from the brake mechanism and the support surface by a sufficient distance.

In another embodiment, the lift mechanism further comprises a lever pivotable relative to the frame about a lever axis for manual manipulation of the lift mechanism, and a linkage connecting the lever to the carriage for transmitting movement of the lever to the carriage. A full stock roll can be very heavy. The control lever allows the operator to manually lift the stock roll.

Preferably, the at least one blocking element is arranged to block a pivoting movement of the control rod about the control rod axis in a position corresponding to a neutral position of the bracket. Thus, the neutral position of the stand may be maintained indirectly by blocking the pivotal movement of the lever. This has the advantage that the blocking element can be located close to the control rod and thus within the reach of the operator. The control rod and the blocking element can thus also be operated simultaneously.

More preferably, the at least one blocking element comprises a hook, the blocking of the pivotal movement of the control lever about the control lever axis by the at least one blocking element being effected by engagement of the control lever with the hook. The hook may be an effective means of blocking further movement of the control lever in a particular direction, in this case the direction corresponding to the direction of lowering of the roll. The control lever can be moved freely out of the hook in the opposite direction, beyond the neutral position, for example to move the hook aside before lowering the support and the roll supported thereon.

More preferably, the catch of said at least one blocking element is arranged to catch the lever from behind when said lever passes through the top rest centre position, lowering the carriage from the operating position towards the discharge position. Once the control rod has passed the top dead center position, the lift mechanism will tend to pull the control rod in a direction corresponding to the direction in which the roll is lowered due to the weight of the roll. By engaging the lever as it passes through the top dead centre position it is ensured that the lever is constantly inclined to remain engaged with the hook. The engagement of the control lever with the hook can only be released when a counterforce is applied, for example pulling the control lever in the opposite direction.

Additionally or alternatively, the hook is rotatable between a blocking position, in which the hook interferes with the pivotal movement of the control lever about the control lever axis, and a release position, in which the hook does not interfere with the pivotal movement of the control lever. The hook can thus be moved out of the path of movement of the control rod, thereby facilitating the discharge of the material roll when the support is at the discharge position.

Preferably, the hook is rotatable about a hook axis perpendicular to the control rod axis. Thus, the hook can be moved to the side of the control rod.

In another embodiment, the bracket includes two arms that are pivotable relative to the frame about a common arm axis that is parallel to and spaced from the roll axis. The arms may effectively support the reel spools on either side of the roll.

The various aspects and features described and illustrated in this specification may be applied separately or randomly. These various aspects, in particular the aspects and features described in the appended dependent claims, may be carried out by divisional patent applications.

Detailed Description

Fig. 1A,1B,2A,2B,3A and 3B each show a portion of a magazine or magazine 1 for supply to a tire component production facility, a tire component server or a release station (not shown).

The magazine 1 comprises a frame 2 having a base 20 for moving the frame 2 over a support surface G, such as the floor of a factory. The frame 2 is open in a feeding direction L for receiving a roll R and in a discharging direction U for discharging the roll R. The material roll R can be a material storage roll or a cloth laying roll. The figure shows the location of only one roll. Typically, the frame 2 extends on one side (not shown) to support another roll, such as a blanket roll, in a parallel arrangement with the stock roll.

The storage box 1 further comprises a lifting mechanism 3 for lifting the material roll R. The lifting mechanism 3 comprises a support 30 for supporting the roll R and defining a roll axis a. The roll R is rotatable about a roll axis a relative to the support 30 for the purpose of roll or loose stock. In this embodiment the bracket 30 comprises two arms 33,34 which are pivotable relative to the frame 2 about a common arm axis B which is parallel to and spaced from the stub shaft axis a. Preferably, the arms 33,34 extend parallel to each other on opposite sides of the roll R to support or carry the shaft S associated with the roll R. As shown, each arm 33,34 has a concave finger or seat 35 for receiving the shaft S. The seat 35 is open in an upward direction, allowing the unloading of the roll R, for example when the arms 33,34 are lowered to a position in which the roll R has been supported on the support surface G and the arms 33,34 are disengaged from the axis S of the roll R.

As shown in fig. 1A,2A and 3A, the carriage 30 is movable between different positions, in this case by rotation of the arms 33,34 about the arm axis B. Fig. 1A illustrates a discharge position in which a roll R is lowered onto a support surface G for loading and/or unloading purposes. Fig. 2A illustrates an operating station in which a roll of material R is lifted from a support surface G for supply to a tire component server. Fig. 3A shows an intermediate position, which is located between the operating position (fig. 2A) and the discharge position (fig. 1A). The reel axis a defined by the cradle 30 extends at a discharge height H1 in the discharge position (fig. 1A), at an operating height H2 in the operating position (fig. 2A), and at an intermediate height H3 between the discharge height H1 and the operating height H2 in the intermediate position (fig. 3A).

As shown in fig. 2A, the magazine 1 is further provided with a brake mechanism 4 for braking rotation of the roll R about the roll axis a when the stand 30 is in the operative position. When the magazine 1 is docked to the tire component server, the brake mechanism 4 is automatically operated in a known manner to release the rotational freedom of the roll R. When the magazine 1 is not docked into the tire component server, the braking mechanism 4 is automatically activated. In this example, the braking mechanism 4 comprises a brake shoe 40, which is arranged on the shaft S directly engaging with the material roll R, so as to brake the rotation of said material roll R by frictional contact with the shaft S. Alternatively, the braking mechanism 4 may be engaged directly on the roll R, for example on some of its rims.

The detent mechanism 4 is preferably located or mounted at a fixed height on the frame 2, the extent of which is limited to the fixed height of the detent mechanism 4 on the frame 2 if operable in the height direction towards or away from the axis S. In any event, when the shaft S is supported at the bracket 30 at the mid-position mid-height H3, the brake mechanism 4 does not reach or engage the shaft S, as shown in FIG. 3A. In other words, the support 30 is arranged in the intermediate position to physically isolate the roll R from the braking mechanism 4.

The lifting mechanism 3 further comprises a control lever 31 which is pivotable relative to the frame 2 about a control lever axis P, so that the lifting mechanism 3 is manually operated. The lifting mechanism 3 has a link or link 32 which connects the control rod 31 with the support 30 so as to transmit the movement of the control rod 31 to the support 30. The link 32 is connected to the control rod 31 eccentrically with respect to the control rod axis P. In other words, the position at which the link 32 is connected to the lever 31 is spaced apart from the lever axis P. The link 32 is also eccentrically connected to the support 30, more specifically to the arms 33,34 of the support 30, at a position spaced from the arm axis B. The link 32 may be hinged relative to the lever 31 and the bracket 30. Thus, the link 32 may translate rotation of the lever 31 about the lever axis P into substantially linear motion of the link 32, which is then transferred to the carriage 30, where the linear motion is translated into rotation of the carriage 30 about the arm axis B. Of course, many variants, in particular linked variants, are conceivable as long as a similar transmission of the control rod 31 to the support 30 can be produced.

Due to the eccentric connection between the link 32 to the control rod 31, the control rod 31 can pass through the top rest centre position, i.e. the position in which the link 32 happens to pass through the control rod axis P pulling the control rod 31 down. On either side of the top dead centre position, the weight of the carriage 30 and the roll R supported thereon pulls the control rod 31 down. Fig. 1A shows the situation where the weight of the bracket 30 and the roll R pulls the control rod 31 down until the bracket 30 is at the discharge position. Fig. 2A shows the weight of the cradle and roll R pulling the lever 31 to the other side of the lever axis P to the operating position. The carriage 30 can only be moved out of the discharge position shown in fig. 1A and the operating position shown in fig. 2A if sufficient reaction force is provided to the control rod 31. Thus, the bracket 30 is prevented from being accidentally moved out of any of the positions.

As shown in fig. 1B,2B and 3B, the magazine 1 comprises at least one, and for example two, blocking elements 51,52 for blocking the lifting mechanism 3 and thus the movement of the carriage 30 in the intermediate position shown in fig. 3A and 3B. The support 30 is arranged in a central position in which the support roll R is disengaged from the braking mechanism 4 and is spaced from the support surface G. In particular, as can be seen in FIG. 3A, the axis S of the roll R is physically isolated from the brake shoe 40.

In the intermediate position, when the magazine 1 is not docked with the tire component server, the roll R can be rotated manually and freely, for example for the purpose of relocating or rolling the magazine roll R or the blanket roll. In particular, the brake mechanism 4 for preventing the roll R from rotating can be circumvented when the magazine 1 is not docked to the tire component server. And since the roll R is not completely lowered to the support surface G, there is no direct contact with the support surface G, and the roll R is still rotatable.

In the present exemplary embodiment, the blocking elements 51,52 serve to block the pivoting movement of the control rod 31 about the control rod axis P in a position corresponding to the neutral position of the support 30.

As shown in fig. 3B, each blocking element 51,52 comprises a hook 53. Said hook 53 is arranged to engage with the control rod 31 so as to block the pivoting movement of the control rod 31 about the control rod axis P. The hook 53 is rotatable between a blocking position, as shown in fig. 3B, in which the hook 53 interferes with or intersects the path of pivotal movement of the control rod 31 about the control rod axis P, and a release position, as shown in fig. 1B or 2B, in which the hook 53 does not interfere with the pivotal movement of the control rod 31. Preferably, the hook 53 is rotatable about a hook axis C perpendicular to the lever axis P.

It should be noted that the hook 53 of said at least one blocking element 51,52 is arranged to hook behind the control rod 31 when said control rod 31 passes through the top rest centre position, lowering the carriage 30 from the operating position towards the unloading position. Once the control rod 31 passes the top dead centre position, the lifting mechanism 3 will tend to pull the control rod 31 in a direction corresponding to the lowering of the roll R due to the weight of the roll R. By engaging the lever 31 when the lever 31 passes the top rest centre position, it is ensured that the lever 31 constantly tends to remain engaged with the hook 53. The engagement of the lever 31 with the hook 53 can be released only when a reaction force is applied, for example, pulling the lever 31 in the opposite direction.

Alternatively, the blocking elements 51,52 may engage directly with the roll R, for example near the axis S of the roll or on the rim of the roll R.

It should also be noted that in theory one blocking element 51,52 is sufficient to block the lifting mechanism 3, provided that the lifting mechanism 3 is sufficiently rigid to remain in the neutral position with only one side blocked.

It is to be understood that the above description is intended to illustrate the operation of the preferred embodiments and is not intended to limit the scope of the invention. Many variations, modifications, or combinations that are apparent to those skilled in the art based on the above discussion are intended to be included within the scope of the present invention.
