The present patent application for industrial invention relates to an installation for manufacturing shoes as disclosed in independent claim 1.
The installations used for manufacturing shoes currently consist in an assembly line along which the article to be produced travels and passes through multiple operating stations provided along the assembly line.
In each operating station an operator and/or machine works on the product that is temporarily stopped in the operating station in order to undergo structural or aesthetic modifications.
After the product has passed through the assembly line and has undergone the necessary operations in each operating station, the desired shoe is obtained and stocked in the warehouse.
The assembly line is generally composed of a conveyor device, whereon the shoe is placed in order to travel through the multiple operating stations where it is machined or finished with additional parts in order to obtain the finished product in the shortest time possible.
Similar installations are impaired by the lack of flexibility because the same assembly line cannot be adjusted to produce a variety of shoes that differ in their structure or in the type of work to be carried out.
The purpose of the present invention is to devise an installation for manufacturing shoes, characterized by:
These purposes are achieved according to the invention with the installation, whose characteristics are listed in the independent claim 1.
Advantageous embodiments of the invention appear from the dependent claims.
The installation of the invention comprises:
In particular, said island for finishing a pump shoe and a sandal or a boot comprises: a suction machine, a seam beating and ironing machine and a brushing machine.
The advantages of the installation according to the present invention are evident because it allows for manufacturing different models of shoe simultaneously, thus reducing production time and cost.
For the sake of clarity the description of the installation according to the present invention continues with reference to the attached figures, which only have an illustrative, not limiting value, wherein:
Referring to
Said transfer device (13) that moves said mobile frame (11) between at least two islands (1,2,3,4,5,6,7,8,9,10) comprises two parallel conveyor belts (13); said islands (1,2,3,4,5,6,7,8,9,10) being interposed between said two conveyor belts (13), each mobile frame (11) being adapted to move from said conveyor belts (13) to the actuation device (12) provided in each island (1,2,3,4,5,6,7,8,9,10), as shown in
The aforementioned figures show the route traveled by a shoe inside the installation of the invention according to the type of the shoe, i.e. a sandal, a pump shoe or a boot.
The installation of the invention comprises:
Each shoe must necessarily pass through said 3 areas (A1, A2, A3) in order to be manufactured.
More precisely, the shoe and the relevant parts are positioned on said mobile frame (11), which follows a predefined route according to the type of shoe to be manufactured.
The first area (A1) is provided with:
The two islands (1,2) used to prepare-assemble a pump shoe or a boot comprise the following machines; cement feeder (A), seam beating and ironing machine (B), counter molding machine (C), mechanical nailing machine (D), crimping machine (Q), toe puff applying machine (E), grinding machine (H), pneumatic nailing machine (I), two different types of toe lasters (P), one humidifier (U) and one trimming machine (L).
The island (3) used to prepare-assemble a sandal and/or finish a heel comprises the following machines: seam beating and ironing machine (B), dehumidifier oven (F), pneumatic nailing machine (I), brushing machine (S), and humidifier (U).
With reference to
The island (4) used to age a boot comprises the following machines:
The four islands (5,6,7,8) used to make machining operations on the bottom and/or on the heel of boots or pump shoes or sandals comprise the following machines: lining ironing machine (SF), seat and side lasting machine (O), pneumatic nailing machine (I), dehumidifier oven (F), pneumatic hammer (MP), ironing machine (N), brushing machine (S), automatic heel seat pounding machine (BO), grinding machine (H), riveting machine (K), suction bench (Z), reactivating oven (J), heel screwing machine (AT), sole pressing machine (PS), refrigerator (G), last removing machine (M), and heel nailing machine (IT).
With reference to
The island (9) used to finish a pump shoe and a sandal comprises the following machines: suction bench (Z), seam beating and ironing machine (B), iron (FS), forming machine (SI), water veil cabin (R), and brushing machine (S).
Said island (10) used to finish a boot comprises the following machines: suction bench (Z), seam beating and ironing machine (B), boot ironing machine (V), and brushing machine (S).
As shown in the attached figures, each island comprises some benches (T) where the operators can place the shoe during the manufacturing cycle.
