Abstract

<P>PROBLEM TO BE SOLVED: To achieve smooth automatic transfer by removing the depression of a valley existing between both conveyers when transferring from a low-speed belt or chain conveyer to a high-speed conveyer. <P>SOLUTION: Left end driven toothed wheels 14 for a second conveyer having the same numbers, the same widths and the same diameters as those a plurality of right end driven toothed wheels 9 for a first conveyer, overlap alternately one by one and fitted to the drive shaft 5 of a common mount 1, and the narrow belts or chains of the first and second conveyers are supported by the toothed wheels 9, 14 having the same diameters around the same drive shaft 5. Thereby, an object or people on the first conveyer can be horizontally transferred to the second conveyer without causing steps. The rotational speed of two motors 4, 12 with reduction gears is changed, and thereby it is possible to transport loaded objects while increasing or decreasing the speed by transfer. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  Improving the loading and unloading action of belts or chain conveyors

  Normally, when getting on and off from the end of a belt or chain conveyor, the tip of the shoe tip is prevented by a comb-shaped tread board attached to the floor, but since the posture is found to suddenly get down to the stationary floor, the speed of the conveyor is increased. Is not preferable for safety.

Problems to be solved by the invention

  When a low-speed short conveyor is installed at both ends of the conveyor and gets on and off, it is possible to increase the running speed of the central conveyor by first riding on this short conveyor and transferring to the central long conveyor. However, at the end of these two conveyors, the belt descends along the circular wheel, so there is a valley between the next conveyor and the connection is not horizontally continuous. . The main body invention eliminates the depression of the valley and automatically transfers to a high-speed conveyor rather than a low-speed conveyor.

Means for solving the problem

  The invention of the main body is a method of pulling the belts or chains of two conveyors into a common frame, and has the same number of same widths as the right end drive toothed wheels 9 for the first conveyor on the drive shaft 5 of the common frame 1. The left end driven toothed wheels 14 for the second conveyor of the same diameter are alternately overlapped and fitted one by one. The right end driving toothed wheel 9 for the first conveyor is fixed to the drive shaft 5 by the spline 7 and is used for the second conveyor. After the left end driven toothed wheel 14 is mounted so as to be freely rotatable via a bearing 8, the right end driven toothed wheel 9 for the first conveyor and the left end driven toothed wheel of the single stand 2 for the first conveyor A plurality of endless narrow belts 11 or chains are attached to 10 so that they can be driven rightward by the motor 4 with the first speed reducer, and for the second conveyor that freely rotates. The end driven toothed wheel 14 and the second conveyor stand 3 are rotated by the second speed reducer motor 12 in the same direction. The right end driving toothed wheel 13 has a number of endless narrow belts. 15 or the chain is mounted so as to be sandwiched one by one in the belt 11 of the first conveyor or the gap of the chain, so that the narrow belts or chains of the first and second conveyors have the same drive shaft 5 and the same diameter toothed wheel Since it is supported by 9 and 14, the object or person on the first conveyor can be transferred to the second conveyor horizontally without any step, and the number of rotations of the motors 4 and 12 with two speed reducers Is changed so that the load can be transported at an increased or decreased speed by transfer.

The invention's effect

  In factories or warehouses, articles are placed on a low-speed short conveyor by a robot hand, etc., and are automatically transferred to a high-speed conveyor that is faster than a short conveyor, or transferred to a low-speed short conveyor and placed on a roller conveyor shelf. It becomes possible to push and store, and the time can be greatly reduced.

  By attaching a low speed short conveyor before and after a conveyor such as a belt or chain that carries humans, first ride on a low speed short conveyor, and after this, automatically transfer to a high speed conveyor and move for a long distance Once this is done, it will be automatically switched to a low-speed conveyor, and then it will be possible to get off the floor. The first and last conveyors are low speed and keep safe for getting on and off.

BEST MODE FOR CARRYING OUT THE INVENTION

  As shown in FIGS. 2, 3 and 4, the drive shaft 5 of the shared gantry 1 has the same number and width as the right end drive toothed wheels 9 for the first conveyor, and the left end driven for the second conveyor of the same diameter. The thickness of the toothed wheels 9 and 14 in which the toothed wheels 14 are alternately overlapped and fitted one by one is preferably 7 mm or less in the case of human transportation. The first conveyor right end drive toothed wheel 9 is fixed to the drive shaft 5 by a spline 7. The second conveyor left end driven toothed wheel 14 is attached via a bearing 8 so as to freely rotate.

  Around the toothed wheel 9 for driving the right end of the first conveyor and the toothed wheel 10 for driving the left end of the single conveyor 2 for the first conveyor, there is a long endless of the same width as the thickness of the toothed wheels 9 and 10. A belt 11 or a chain provided with teeth on the inner circumference is attached and driven to the right by a motor 4 with a first speed reducer installed on the shared mount 1 to convey a mounted object or person.

  The belt 11 is led to a multi-guide groove 17 provided with a wide receiving plate 16 at a position away from the toothed wheel, and can withstand a load from above.

  Further, there is a free-rotating left-side driven toothed wheel 14 for the second conveyor and a single carriage 3 for the second conveyor, around the right-sided driving toothed wheel 13 that is rotated in the same direction by a motor 12 with a second speed reducer. The endless belt 15 or chain having teeth on the inner circumference of the same width as the thickness of the toothed wheels 14 and 13 is mounted so as to be sandwiched one by one in the gap of the belt 11 or chain of the first conveyor. Therefore, the narrow belts or chains of the first and second conveyors are supported by the same driving shaft 5 and the toothed wheels 9 and 14 having the same diameter. And can be automatically transferred to the second conveyor horizontally.

  By changing the rotation speed of the two motors 4 and 12 with a speed reducer, the load can be transported at an increased or decreased speed by transfer.

  The connection operation mechanism of the first conveyor and the second conveyor can be used between the second conveyor and the third conveyor, and the connection operation can be continued for many units in this way. Therefore, even if it rides on the almost stationary conveyor, it can be automatically transferred to the second and third conveyors and transported at high speed. In the case of deceleration, the vehicle can be decelerated to almost a stationary state.

  5, FIG. 6, FIG. 7 and FIG. 8 show an example of the structure of the narrow belts 11 and 15 for the belt conveyor, and FIG. 5 shows that the steel plate such as spring steel is bent as shown in the cross section of FIG. FIG. 7 is a belt having a structure in which a rubber or synthetic resin belt reinforced with cloth or steel wire is bonded to a steel plate belt of spring steel or the like, and a wire mesh instead of the steel plate belt. May be used.
