Description

  The present invention relates to a solid tire press machine.

  Unlike a pneumatic tire, a solid tire does not have a tire tube containing air. For this reason, when assembling a solid tire with a wheel by a tire press machine, the press-fit pressure for fitting the wheel to the inner diameter part of the tire is very high compared to that of a pneumatic tire. Therefore, a high-pressure tire press is required for assembling the solid tire, and the press-in pressure increases as the tire diameter increases.

  In a conventional solid tire press machine, a solid tire and a wheel are carried into and out of the press machine by a lifting device such as a chain block as shown in FIG. 3, and a lift device for a press machine as shown in FIG. In general, a configuration that does not include the above-described transport device is provided.

  In the press-in operation using such a conventional solid tire press machine, particularly in the case of a large-diameter solid tire, there is a risk in carrying in and out the solid tire and the wheel into the press machine. Setting a heavy solid tire to a tire press while controlling the posture with a chain block etc. by human power was an unstable operation and was also inefficient.

  Patent Document 1 describes an article loading / unloading apparatus that can place a tire, a wheel, or the like and move it up and down and convey it to a press-fitting machine.

Japanese Patent Laid-Open No. 2002-2243

  However, since the apparatus configuration of Patent Document 1 is a separate apparatus from the press-fitting machine body, a dedicated space is required.

  This invention makes it a subject to provide the solid tire press machine provided with the conveyance apparatus of a tire and a wheel which can perform the said press injection operation | work more safely and efficiently.

In order to solve the above-mentioned problems, the invention of claim 1 is a solid tire press machine for inserting a wheel for a solid tire into a solid tire, which is disposed in the center of the ceiling of the portal stand and operates in the vertical direction. Comprising a hydraulic press device, a press stand disposed at a lower portion of the hydraulic press device, a transport stand for loading / unloading solid tires and wheels on the press stand, and a lifting device for the transport stand, It is characterized by being configured to be rotatable in the horizontal direction with one pillar of the portal stand as a fulcrum.
Further, the invention of claim 2 further includes a swivel arm in which the carriage can be rotated in the horizontal direction, a base part disposed on the swivel arm and supporting the solid tire and the wheel, and left and right sides of the base part. The first and second tire support portions are connected to each other by hinge structures and support the solid tire and the wheel together with the base portion, and the first and second tire support portions each have a large and small arc shape. , An end portion that is continuous with the two arc-shaped end portions, and a hinge portion that is continuous with the two arc-shaped end portions on the opposite side of the end portion and is connected to the base portion. .

  The solid tire press machine of the present invention is constructed by compactly incorporating a horizontal rotation type carriage with a lifting device into a gate-type stand, realizing space saving and a solid tire and wheel press machine It is possible to safely and efficiently carry in / out work regardless of tire size and weight.

BRIEF DESCRIPTION OF THE DRAWINGS It is an assembly drawing of the solid tire press-fitting machine which shows one Example of this invention, (a) is a front view, (b) is a top view. It is a perspective view of a solid tire press machine showing one example of the present invention, (a) shows a state where a conveyance stand is in a solid tire placement position, and (b) shows a state where a conveyance stand is in a solid tire press injection position. . It is a perspective view which shows an example of the conventional tire press-fit machine and the raising / lowering apparatus. It is a perspective view of the conventional tire press-fit machine (without raising / lowering apparatus).

  Hereinafter, an embodiment of a solid tire press machine of the present invention will be described with reference to the drawings. First, the configuration will be described.

As shown in FIGS. 1A and 1B, a hydraulic press device 3 that is disposed at the center of the ceiling portion 2 a of the portal stand 2 and operates in the vertical direction, and a lower portion of the hydraulic press device 3. A press table 3a, a transport table 4 for loading / unloading the solid tire 6 and the wheel 7 to / from the press table 3a, and a transport table lifting / lowering device 5 are provided.
As shown in FIGS. 2 (a) and 2 (b), the turning arm 4a of the carriage 4 can be rotated in the horizontal direction with a horizontal rotation fulcrum 4i disposed on one column 2b of the portal stand 2 as a fulcrum. It is configured.

The transport table 4 has a swing arm 4a that can be rotated in the horizontal direction, a base 4b that is disposed on the swing arm 4a and supports the solid tire 6 and the wheel 7, and hinge structures on both the left and right sides of the base 4b. And the first and second tire support portions 4c and 4d that support the solid tire and the wheel together with the base portion 4b.
The first and second tire support portions 4c and 4d each have two large and small arc-shaped end portions 4e and 4f, a tip portion 4g continuous with the two arc-shaped end portions, and two facing sides of the tip portion 4g. It has a hinge portion 4h that is continuous with the arc-shaped end portions 4c and 4d and is connected to the base portion 4b.

  Of the first and second tire support portions 4c and 4d, the length L1 of the arc-shaped end portion 4e of the first tire support portion 4c on the side close to the horizontal rotation fulcrum 4i of the turning arm 4a is set to the other second. By making the length L2 shorter than the length L2 of the arcuate end 4e ′ of the tire support 4d, that is, L1 <L2, it is possible to cope with the conveyance of a small-diameter solid tire, and a wider range. It is possible to correspond to the tire diameter.

Next, a procedure for press-fitting the wheel 7 into the solid tire 6 by the solid tire press 1 of the present embodiment will be described.
First, the turning arm 4 a of the transport table 4 is rotated and pulled out of the portal stand 2 of the solid tire press-fitting machine 1 and lowered to the lower limit position Q by the lifting device 5. Next, the opening degree of the first and second support portions 4 c and 4 d is adjusted according to the diameter of the solid tire 6. Specifically, the opening is such that the solid tire 6 is stably placed on the first and second support portions 4c and 4d.

  Next, the solid tire 6 and the wheel 7 are placed concentrically on the first and second support portions 4c and 4d by means such as a chain block or human power. And it raises to press height P with the raising / lowering apparatus 5. FIG. The lifting device 5 can be raised to the upper limit position R.

  Next, the turning arm 4a of the transport table 4 is rotated into the portal stand 2 of the solid tire press-fitting machine 1 and set at the press position. Then, the hydraulic press device 3 is lowered to press-fit the wheel 7 into the inner diameter portion of the solid tire 6.

  In the press-in operation of the solid tire and wheel described above, when the solid tire press-fitting machine according to the present embodiment is used, the solid tire and wheel, which are heavy objects, are in an unstable state, for example, slanted with a chain block. Therefore, it can be safely transported in a stable state at all times.

  This is because solid tires and wheels can be set on the swivel arm of the transport table with a certain easy work regardless of the size and weight of the tire. This is because it is a safe operation of rotating the turning arm portion of the transfer table.

  In addition, the transport platform with this swivel arm and its lifting device are installed in the portal stand of the solid tire press, and can be stored inside the portal stand when not in use, saving space in the work area. Can be achieved.

  The solid tire press according to the present embodiment makes the work conditions that differ depending on the tire size and weight constant, so that the reliability of the work is dramatically improved, and the safety and efficiency of the work are also improved. .
