Description

Machine to assemble boxes from cuts of material with improved performance.

Scope and prior art

The present invention is related to a machine to form or assemble boxes from a cut of essentially sheet-shaped material, for example cardboard, plastic and the like having a plurality of folding lines and notches through which Set up the box.

As is known, these types of machines start from material cuts that are pre-configured with folding lines and notches to form a packing box, and that are fed from a stack to a pressing station where they are properly configured.

These types of machines consist essentially of a machine frame with means of feeding the cuts of material and forming means provided in the form of a mandrel of pressure that are mounted on a machine bridge, so that the material cuts are transported to their position of shaping below the shaping means.

A problem that results in this type of machines It originates in getting a fast and accurate placement of cuts of material to be formed against the forming means, since the performance and production quality of the machine They depend directly on both factors.

For the movement of material cuts the use of motors is known until its pressing position Asynchronous electric with braking elements that on the one hand introduce a slow factor and on the other a difficult regulation of the stop position and which also have a short duration operational due to such braking efforts.

Object of the invention

The invention aims at the development of a machine of the type indicated at the beginning that allows solve the problems of the technique before mentioned.

According to the invention, this task is achieved from a machine comprising:

-

a rack of machine with a horizontal bench plane in which they are provided means of feeding the material cuts to conform that they have means of transport to place the material cuts in the horizontal bench plane and means of introduction that lie on the aforementioned horizontal plane for move a cut of material to be formed to a position by under a mandrel-shaped shaping means of pressure that are mounted on a bridge that lies above the bench plane,

where,

-

the means of transport comprise a rotating frame with a suction cups of capture,

-

the means of Introduction include endless chains with translation nails of the material cut, a chain guide, drive pinions the chain, and

-

the means of conformation comprise a pressure plate, for acting on the cut of material to be formed, mounted on the end bottom of two mobile guide columns on guide supports fixed on the bridge to move from top to bottom on a perpendicular to the horizontal bench plane on which lay the cuts to conform and a zipper that extends parallel between the two guide columns,

said machine being characterized by how much:

-

a first servomotor it is planned for the dragging of the media chains of introduction by means of a second chain that meshes between a servo motor output pinion and another pinion mounted on the shaft the chain drive sprockets, and

-

one second servomotor is fixedly provided on the bridge to engage on the zipper of the forming means through its output pinion and a rack guide.

As will be appreciated by the technicians, the speed / precision ratio achieved by servomotors is much larger than that achieved by motors conventional, so that yield and production quality of the machine improve in an essential way through an exact and fast placement of material cuts in the position of conformation. In addition, the use of said servomotors provides numerous operating advantages both in the mechanical aspect as electrical.

Brief description of the drawings

Other features and advantages of the invention will result more clearly from the description that follows, which has been made with the help of the attached drawings relating to a example of non-limiting execution and in which:

Figures 1A and 1B show respective views general perspective of a machine for forming boxes according to the invention mounted and partially disassembled.

Figures 2A and 2B illustrate respective views. in perspective of the means of transport and introduction of cuts of material to conform.

Figures 3A and 3B show respective views of the means of forming the material cuts.

Detailed description of an embodiment

As seen especially clearly in Figures 1A and 1B, the machine according to the invention, designated in general with reference 1, is constituted by a frame of machine 2 that determines a horizontal bench plane 3 in which feeding means 4 are provided to supply the C-shaped material cuts that include means of transport 5 to place the material cuts in the plane horizontal bench and introduction means 6 that lie on said horizontal plane to translate a cut of material to be formed to a position below about forming means 7 in the form of a pressure mandrel which are mounted on a bridge 8 arranged above said plane of bedplate.

Referring now to Figure 2A, appreciate that the transport means 5 have a rotating frame 50 and a suction cups 51 to move the material cuts C to the horizontal bench plane 3.

As can be seen in greater detail by the Figure 2B, the introduction means 6, are constituted by a pair of endless chains 60 with nails 61 for cutting translation of material C, which run parallel to each other on a guide chain 62 and which are driven by drive pinions 63 operated through a first servomotor 64 and through a second chain 65 that meshes between an output pinion 66 of said servomotor and another pinion 67 mounted on an axis the aforementioned drive pinions 63.

As shown by Figure 3A, the means of conformation 7 are mounted on the bridge 8 and comprise a pressure plate 70, for action on cutting material a conform, which is mounted on the lower end of two guide columns 71 movable on guide supports 72 which are fixed on said bridge 8, so that they can move in swing from top to bottom on a perpendicular to the horizontal plane of bed on which the cuts of material to form and a zipper 73 that extends parallel between the two mentioned guide columns that is operatively coupled to a second servomotor 74, fixedly provided on bridge 8, through a output pinion 75 of the servo motor and a rack guide 76

Next and with reference to the figures 2A, 2B and 3A, the operating steps of the shaping machine

First, as shown by the figure 2A, the cuts of material C, are collected by the means of transport 5, for example from a stack or the like, by suction cups 51 and by turning its frame 50 are deposited on the means of introduction 6 which then as Figure 2B shows, by means of its fingernails 61 it displaces until introducing said material cuts below the means of conformation 7, so that its pressure plate will push said cut through its center to form a box as shown by Figure 3A

The use of servomotors 64, 74 in the respective means of introduction and conformation, allow get a speed / precision ratio that is much greater than the achieved by means of conventional motors, so that the machine performance and production quality improve so  essential through an exact and fast placement of the cuts of material C in the forming position. Moreover, these Servo motors provide numerous operating advantages both mechanically and electrically and have ample possibilities of regulation and control.

Enough that the object of the invention only remains to point out that the embodiments derived from changes in form, equivalent elements and the like, as well as those derived from a routine application of what previously disclosed, should be considered included in your scope, so that the invention will only be limited by the scope of the following claims.
