Description

[Detailed Description of the Invention] The present invention relates to a cart holding device loaded with paan or cheese.

When loading paan or cheese from a winding device onto a trolley using a transfer device and transporting it to an inspection or voltage detection line, a trolley A (first
), the paan or cheese P is inserted into the peg and transported to the conveyor installation position of the inspection and packaging line, and the paan or cheese loaded on the trolley is transferred onto the conveyor using a transfer device.

The operation of transferring paan or cheese from the cart to the conveyor involves transporting the cart loaded with paan or cheese to a predetermined transfer position, holding the cart with a fork, etc., raising it to the chuck operating position of the transfer device, and finally transferring the paan or cheese to the conveyor. The paan or cheese inserted into the upper pegs is simultaneously gripped by a chuck mechanism, extracted from the pegs, and transferred onto the conveyor.

When the topmost layer of paan or cheese has been transshipped, the next layer of paan or cheese is raised to the chuck operating position, gripped by the chuck mechanism, extracted from the peg, and transferred onto the conveyor.

The cart is sequentially raised by the vertical interval of the pegs to perform transshipment.

The holding device for raising the cart loaded with the paan or cheese at predetermined intervals is provided with a fork that is movable up and down and that extends and retracts from the machine frame in a direction perpendicular to the conveyance direction of the cart, and
A convex portion that engages with a positioning recess provided on the underside of the truck is attached to the upper surface of the fork, thereby positioning the truck and fixing the truck on the fork.

However, in the cart holding device with the above structure, since the cart and fork are provided with concave and convex portions for positioning and securing, a large number of carts must be provided with engagement recesses, making it impossible to use the existing carts as they are, and There were drawbacks that required a lot of time and money to improve.

Furthermore, it is difficult to ensure that there is no variation in the dimensions of the pegs provided on the cart for inserting the parn or cheese and the recesses that engage with the projections of the fork.

As a result, when transshipping paan or cheese, it is not possible to hold the trolley in a predetermined position and move it up and down, resulting in grasping errors.
If the bread or cheese is damaged, it has the disadvantage that it loses its commercial value.

The present invention was developed as a result of studies aimed at solving the drawbacks of the conventional truck holding device.

That is, the present invention includes a lifter provided on the machine frame so as to be able to rise and fall freely, a positioning means provided at one end of the lifter that protrudes and retracts in a direction perpendicular to the direction of transport of the cart and comes into contact with the front part of the cart, and a positioning means provided at the other end of the lifter. a clamping means that protrudes and retracts in a direction perpendicular to the direction of carriage of the carriage and abuts the rear part of the carriage and clamps the carriage with the positioning means; The present invention provides a truck holding device that accurately and reliably holds a truck in a predetermined position and raises and lowers the truck, which is made up of a fork and a lifting means for the lifter.
