Description

Pallet conveying device

The utility model relates to a kind of endless chain feedway in the conveying technology, is meant a kind of pallet conveying device especially.

Conventional chain-type pallet conveying device as shown in Figure 1, normally on parallel guide rail 1, install chain 2, this chain 2 must be driven by sprocket wheel 3, and holds thereon and carry supporting plate 4 in the mode of bridging and carry object for putting, and the propelling movement of the friction thrust between mat chain 2 and supporting plate 4 each contact surface supporting plate 4; But above-mentioned pallet conveying device has following shortcoming in the use:

1, is subjected to bigger resistance and when failing to cooperate chain 2 advanced in unison, promptly can makes the supporting plate 4 at rear that overtaking collisions take place, at this moment when the supporting plate 4 in the place ahead, unless stop this chain 2 runnings, otherwise aforesaid friction force still can push supporting plate 4 and move forward, therefore, causes the work flow disorder easily.

2, its chain 2 is to be exposed state, and the chance that the staff touches accidentally is big, and is dangerous high; And cover dirt or stuck easily by other foreign matter, not only keep in repair cumbersome and the fault probability also higher.

The purpose of this utility model is to propose a kind of pallet conveying device of mainly being made up of pair of base and some transportation groups, and it can change delivery speed according to bearing pressure or the size that meets obstructions, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is to include: pair of base, and it is put with parallel and the preset distance ground row of being separated by;

Some delivery groups are arranged on this pedestal respectively symmetrically; Wherein each delivery groups includes:

One rectangular body, its Width is provided with a plurality of through holes; The recessed respectively symmetrical shoulder that forms of the inwall of two open ends of this each through hole;

Deng the rotating unit of number in this through hole, this rotating unit respectively has pair of bearings, and it is fixedly arranged on the shoulder of each through hole two end respectively; One axostylus axostyle, it is hubbed on this rectangular body in the mode of axle center perpendicular to this rectangular body length direction, and it is arranged in this to bearing; Its connection of an end that actuator is fixed in this axostylus axostyle drives the chain that this axostylus axostyle rotates; One inner sleeve can be installed with the other end of axostylus axostyle; One outer sleeve, its cover is through at the stack shell of this inner sleeve;

Said delivery groups, it is the end face that is arranged at this pedestal respectively, be resisted against this raised line by a side of this rectangular body broad ways respectively, and respectively this outer sleeve is to be two row and to be located opposite from the respectively inboard of this pedestal, and be placed in the T type groove of this base top surface respectively with the one end respectively by the plurality of fixed part, an outer sleeve is with can be at the mode axle sleeve that rotates with this inner sleeve under the set pressure on the tube face of this inner sleeve; When this delivery groups respectively is arranged in respectively this pedestal respectively, respectively this outer sleeve is two row and is located opposite from the respectively inboard of this pedestal, in order to carrying supporting plate to be carried, during normal operation, respectively this actuator driven in synchronism respectively rotate together by this axostylus axostyle and this inner and outer sleeves, take place and when making binding force between supporting plate and this outer sleeve greater than this set pressure, this outer sleeve does not promptly rotate with this inner sleeve, carries this moment action promptly to be halted state and supplies fault queue as abnormal cause.

The utility model pallet conveying device is to be linked in inner and outer sleeves carrying supporting plate together, the size of its visual pressure that carries or the resistance that runs into and change delivery speed really can be according to the speed of the work flow of manufacturing line and make optimal cooperation; And respectively the chain put of these row is defeated is to be hidden in respectively in this cover cap, also can improve safety in utilization and reduces by the stuck fault rate of foreign matter.
