DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a semiautomatic feeder line particularly for setting-out/drying machines, vacuum-driers, and optionally stakers for industrial hides.
It is known that hides that are wet after tanning or dyeing processes are sammed and set-out by means of a samming/setting-out machine and are then dried by means of a vacuum driers to eliminate residual moisture almost entirely. Finally, they are stretched in a staker to regain their original softness and to increase their surface.
In the first samming/setting-out step, normal production with two operators is approximately 40.div.50 hides per hour. In the second vacuum drying step, production with two operators is approximately 10 hides per hour. The third staking step allows to provide an hourly production rate that is higher than the above mentioned values even with a single operator.
Accordingly, approximately 20-22 operators, with considerable idle times, are required in order to achieve a production of approximately 100 hides per hour. Furthermore, the transfer of the hides between the three above mentioned machines requires the use of beams that must be transferred from one machine to the other, with considerable wastes of time, energy, and labor.
The aim of the invention is to reduce the above mentioned drawbacks, providing a feeder line for setting-out/drying machines, vacuum driers, and optionally stakers of the substantially automatic type that allows to limit the use of labor and increase the productivity of the apparatus.
A particular object is to provide a system for the direct and semiautomatic transfer of the hides between the various units of the apparatus, eliminating idle times, caused by the unloading and loading of the hides on a means for picking up the hides and transferring them from one machine to the next, as well as reducing the assigned personnel and the required energy.
Another object is to provide a semiautomatic line of the above mentioned type that has reduced dimensions and allows to optimize space and to use complete facilities even in small tanneries.
This aim, these objects, and others which will become apparent hereinafter are achieved by a semiautomatic feeder line of the type defined in the introduction, which has the characteristics stated in the accompanying claim 1.
By means of a feeder line according to the invention, considerable time can be saved and therefore high productivity of the apparatus is achieved. The use and fatigue of assigned personnel is reduced and the space required for apparatus management is reduced to a minimum.
Further characteristics and advantages will become apparent from the detailed description of some preferred but not exclusive embodiments of the invention, given by way of non-limitative example with the aid of the accompanying drawings, wherein:
FIG. 1 is a side view of a first embodiment of the semiautomatic apparatus according to the invention;
FIG. 2 is a top view of the apparatus of FIG. 1;
FIG. 3 is a side view of a second embodiment of the semiautomatic apparatus according to the invention;
FIG. 4 is a top view of the apparatus of FIG. 3.
With reference to FIGS. 1 and 2, the semiautomatic line according to the invention, generally designated by the reference numeral 1, has the purpose of transferring whole or half industrial bovine hides P or P' from a first continuous samming/setting-out machine 2 to a vacuum drier 3 with multiple tables and optionally to a staker 4 with beating plates.
By way of non-limitative example, the samming/setting-out machine can be the continuous-cycle model manufactured and marketed by the Bauce company of Trissino, Vicenza (Italy), under the name PRC4 RA 3200, whereas the vacuum drier 3 can be of the type with 5-6 working tables 3', manufactured and marketed by the Cartigliano company of Cartigliano, Vicenza (Italy). The staker 4 can be the Syncro 3200 model, also manufactured and marketed by the Cartigliano company.
According to the invention, the machines 2 and 3 are appropriately arranged in adjacent positions and are connected by a
