Description
Technical Field
The invention relates to the technical field of handcart positioning, in particular to a handcart positioning and locking device for a tire assembly line.
Background
On the tire assembly line, the tires are stacked before being assembled with the rim, and a plastic backing plate is inserted below each stack of tires, and the backing plate bears the stack of tires and is contacted with the roller so as to reduce the conveying resistance on the roller conveyor belt. Each tyre is assembled with a rim and after each stack of tyres has been consumed, the plastic mat needs to be recycled for future reuse. The plastic mat is launched into a ramp device, and the plastic mat slides down the ramp into a cart, where it is stacked in sequence. After being piled up, the vehicle is pushed away by a special person and replaced by an empty vehicle.
In order to allow the plastic pallet to drop smoothly into the cart each time, it is necessary to align the cart with the ramp assembly each time and push it a predetermined fixed distance, i.e., it is necessary to position the cart to a fixed position each time and maintain a fixed orientation. In addition, when the plastic backing plate falls into the handcart along the ramp device, the plastic backing plate has a larger horizontal speed, and can cause larger horizontal impact to the handcart, so that the handcart is shifted, the following plastic backing plate can not fall into the handcart smoothly any more, and meanwhile, the shifting of the handcart can bring potential safety hazard to surrounding personnel, so that the handcart is required to be fixed after being in place. After the plastic pallet in the cart is fully collected, the cart needs to be unsecured and pushed away.
The currently used fixing mode is that an operator faces two universal casters with brakes to the operator, the operator starts the brakes of the two casters with feet to fix the handcart, and when the handcart is required to be pushed away during use, the operator releases the brakes of the two casters with feet, so that the handcart is released from being fixed. Because the handcart is square, and four faces are completely consistent and can face the ramp device, operators need to distinguish the four faces of the handcart, and find out that the faces of the two casters with brakes face themselves. When two brake pedals with brake universal casters just swing to the bottom of the handcart, so that feet cannot touch the brake pedals, an operator can break the brake pedals of the casters to the outside by feet or even hands, and the handcart can shift in the process.
