Abstract

PURPOSE:To enable a device to be positively operated with noise level lowered by arranging an endless belt in the direction intersected with the moving direction of a dolly, driving frictionally the friction wheels provided under-neath the dolly, and thereby rotating a belt pulley in the title device wherein numbers of dollies are moved circularly. CONSTITUTION:Friction plates 41 and 42 corresponding to the friction wheels 11 and 12 of a dolly are provided for the carry-in position and the carry-out sorting position respectively for the circulating route of the dolly 1a. And an endless support belt 7 is wrapped over the dolly 1a, which runs in the direction of the movement of the dolly 1a, that is, the carry-in/out direction of the dolly 1a so that the driving pulley 6 of it is connected with the friction wheels 11 and 12 via a transmitting mechanism 14. In this constitution, the friction plates 41 and 42 are elevated as required at the carry-in position and the carry-out position so as to be brought in contact with the friction wheels 11 and 12. The friction wheels 11 and 12 are therefore rotated while being accompanied with the running of the dolly so that the belt 7 can run. By this constitution, a device can thereby be positively operated with noise level lowered.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention involves circulating a number of carts, loading articles onto the carts at a loading position, and transporting the articles on the carts into a plurality of carts. Carrying out sorting is related to a transport sorting device that sorts articles by type or destination by selectively carrying them out at a certain location.

(Prior art) For example, when an item is transported along a conveyance path, what happens on this conveyance path? ! At several locations, the 11-minute conveyance system was designed to selectively transport items to the side of the conveyor path based on product type or shipping light. There are methods that push the material out to the side, and methods that allow the carts or slabs 1~ that run along the m-feed path to be tilted sideways so that the items on top of them fall to the side due to gravity. However, there are restrictions on the items that can be sorted, such as small items, loose items,
It is difficult to sort items that can only be transported by belt conveyor A7, such as lightweight items, thin items, items with poor bottom surfaces, etc.

An example of a method applicable to the transportation of such items is disclosed in Japanese Patent Application Laid-Open No. 48-98580.

This transport sorting is carried out by attaching an endless support belt (cross belt) to a cart (chassis structure) that moves along the transport path (C rail), which has a transport direction that intersects the moving direction of the cart. This support belt is wound around a drive pulley (roller), and this drive pulley is connected to a friction Φ (binion or pulley) that is disposed at the bottom of the truck so as to be able to swing from side to side. A pair of II m body racks, friction racks, belts, rack devices) and guide devices (guide frames and guide members) on both sides of this 1 , guides the friction wheel of the moving truck to the left and right and engages with one of the pair of friction bodies, whereby the rotation of the friction wheel rolling against the -1 friction body is controlled by the drive pulley. The drive pulley is selectively rotated in the forward or reverse direction in response to the friction body, and the support belt is selectively driven toward one side or the other side of the conveyance path. ing.

(Problem to be Solved by the Invention) However, the conveying and sorting device disclosed in the above-mentioned publication is based on a system in which a friction wheel (binion or pulley) is mounted on the top of a chassis structure so that it can swing in the left and right directions like a pendulum. There is a
During sorting, this friction wheel is attached to a pair of 1! ? Rubbing rack, r! ltp rack,
■Since the structure is such that the friction wheel is guided and engaged with one side of the belt (belt, rack device), it is necessary to center the friction wheel at an intermediate neutral position under normal conditions, making the support structure for this friction wheel complicated. , the number of parts and assemblies increases, and it is difficult to reliably engage the friction wheel with the friction body and maintain this engagement, so the operation tends to be uncertain, and the pendulum-shaped flJm wheel When guiding from side to side, a JJ sound is generated, and since there is always a guide part δ in front of the position in the unloading sorter equipped with an S edge, the distance between the positions of the front and rear unloading sorters becomes wider. There are drawbacks.

The present invention has been made in view of the above points, and is a transport sorting system in which a support belt having a transport direction that intersects with the moving direction of the trolley is provided on a trolley that moves on an endless transport path or circulation path. This is a device that solves problems with structure, operation, and noise, and also allows narrowing the distance between the front and rear discharge sorting positions.

[Efficacy of invention Song Dynasty]

As described above, according to the present invention, an article is placed on the support belt of a trolley, the article is transported by the movement of the trolley, and at a predetermined brokerage, the support belt of the trolley is driven to the side to remove the transported article. When unloading and sorting, by advancing and engaging the friction plate on the transport path or circulation path side with the friction wheel at the bottom of the cart, the I? ! A scrubbing cloth is rolled against a friction plate, and the rotation of this friction wheel is transmitted)3
This structure drives the support belt by transmitting the signal to the support belt at the bottom of the truck through the mechanism and drive pulley. Therefore, since the friction wheel only needs to be fixedly supported, the support structure is simple and the number of parts is reduced. The number of assembly steps is small, and by simply pressing the friction plate against the friction wheel, the friction wheel and friction plate are reliably engaged in the cylinder, and this engagement is maintained as it is, so the operation is reliable, stable, and noise-free. The occurrence of Δ is small, and the carry-out sorting is performed at the position Iv! Since there are no special devices installed before and after the rubbing plate, the distance between the positions can be narrowed for the front tQ carry-out sorting.
