SHEET u. 0F 4 This invention relates to a cutting and clamping tool or assembly more particularly adapted for use in combination into a bundle strapping machine.
In the strapping machine of the prior art, the holding or clamping of the metal strap is made by one assembly while the cutting of the strap is made by another assembly.
The Applicant has found that the clamping and cutting operations may be integrated into a single and simple assembly which holds the initial end of the metal strap during looping of the latter around the bundle and which, upon securement of the strap, moves to a cutting position to concertedly cut the strap and hold the newly formed free end thereof.
It is a general object of the invention to provide an integrated cutting and clamping tool or assembly more particularly adapted for an automatic bundle strapping machine.
It is a more specific object of the invention to provide an integrated cutting and clamping tool wherein the cutting edge and clamping element are arranged side by side for concerted cutting and clamping of a tying element and in particular a metal strap on an automatic bundle strapping machine.
It is a further object of the invention to provide an automatic bundle strapping machine including an integrated cutting and clamping tool or assembly which is arranged for holding the initial end of the metal strap during coiling a turn around a bundle and to effect concerted cutting and clamping of the following portion of the strap after tying the turn around the bundle.
The above and other objects and advantages of the invention should be better understood in the light of the following detailed description of a preferred embodiment thereof, which is illustrated, by way of example, in the accompanying drawings, in which:

FIG. 16 is a partial side elevation view of the automatic strapping machine as seen from the far side in FIG. I
The illustrated automatic bundle strapping machine, as best shown in FIGS. ll, 2, and 16, includes a frame it formed of sheet metal or plates, although it may be formed in any other suitable manner. Transversely aligned apertures 2 are formed into the opposite sides of the frame 1 and arranged to transversely convey bundles 3 in and out of a strapping station within the frame 1. Abutment flaps or plates 4 are integrally formed with the frame or otherwise secured to the latter to form a forward abutment for the bundle 3 at the strapping station. A slot 5, of appropriate width, is left between abutment plates 4 to allow unhindered passage of the strap 6 therein upon looping and tying the latter.
An assembly, of generally known construction, hereinafter called a looping assembly, is mounted onto the frame for forming a turn or loop of the strap 6 around the bundle 3. The looping assembly includes a shaft 7 extending transversely through the frame 1 and rotatably carried by the latter. A motor 8, of any appropriate type, is secured against the front end of the frame and is drivingly connected to the shaft 7 through a sprocket chain 9, in any suitable manner. Radially restrained shafts 10 extend through each side of the frame 1 and each carries an inner sprocket. The upper shafts 10 also carry each an outer sprocket connected by a chain 111 to the transverse shaft 7 to be driven through the latter by the motor 8. An arcuate guide 12 is slidably mounted by pins 13 on the inside of each side of the frame 1. A chain 14 is operatively mounted along each side-of the frame 1 into engagement around the corresponding inner sprockets and arcuate guide 12. The chains 14 and the afore-mentioned driving elements thereof form a conveyor for a carriage to convey the latter peripherally around the bundle 3 in position to be attached. This carriage may be of any suitable detailed construction and is herein schematically illustrated as including a base 15 onto which is mounted a frame 16.
A spool 17, of metal strap 6, is rotatably mounted onto the frame 16 to dispense the required strap for attaching the bundle. A rigid arm I8 is secured to the frame 16 and rotatably carries a pulley 19 to guide the dispensed strap 6 from the spool 17 towards an integrated cutting and clamping tool or assembly 20 which is hereinafter described with particular reference to FIGS. 2, 8a, 9, I0, ll, 15, and 16. The integrated cutting and clamping assembly includes an upwardly extending and inclined guide track 21 into which is slidably mounted a carriage 22, of any suitable construction. A hydraulic cylinder 23 is anchored at one end to a bracket 24 fixed to the frame I and is connected at the other end to the carriage 22 for reciprocating displacement of the latter along the guide track 21.
An elongated casing 25, of rectangular cross-section, is secured to the carriage 22 and extends transversely of the frame 1. A pivot 26 is secured transversely into the casing 25 and, therefore, extends longitudinally of the frame 1. A pair of cutting and clamping jaws 27 and 28 are pivotally mounted onto the pivot 26 and are each formed of laterally juxtaposed plates. The upper jaw 27 includes clamping plates 29 and 30 alternating with a pair of spacer plates 31 and 32. Similarly, the lower jaw 28 includes a cutting plate 33 and a punch plate 34 alternating with a pair of spacer plates 35 and 36. Each of the clamping plate 30 and the cutting plate 33 is formed with a catch or finger 37 arranged to catch the metal strap 6, and upon closing of the jaws to laterally position the latter with the assistance of the ramp 38 for lateral registery with a punch 39 formed onto the punch plate 34. A corresponding cavity is formed into the spacer plate 32 to allow the punch 39 to lodge therein upon closing of the jaws.
A hydraulic cylinder 40 is secured at one end onto the carriage 22 and includes a piston or plunger 41 extending into the casing 25 for to and fro displacement lengthwise thereof. A yoke 42 is secured by a pin 43 onto the inner end of the reciprocating member or piston 41 and extends transversely thereof. Four rigid links or levers 44 are pivotally connected at their opposite ends by pins 45 to the opposite sides of the yoke 42 and of the jaws 27 and 28. There results that the to and fro displacement of the piston 41 is converted into closing and opening respectively of the jaws, as may be appreciated by comparing FIGS. 9 and and the arrows therein.
The automatic bundle strapping machine according to the illustrated invention also includes a crimping assembly 46, the detailed construction of which does not form part of the present invention. The crimping assembly includes a crimping member 47, of any appropriate construction, to crimp a metal clamp 48 around overlapping portions of the strap 6. The crimping member 47 is operatively connected to a hydraulic cylinder 49 to produce reciprocation thereof.
After a bundle 3 has been placed at the strapping station in abutment against the abutment plates 4, the initial or free end of the strap 6 is held fast by the clamping and cutting assembly 20 adjacent the bundle 3. The motor 8 is then operated causing the afore-mentioned conveyor assembly, the base and the associated elements to travel around the bundle. As the spool 17 pro gresses around the bundle, the strap 6 unrolls from the spool and wraps around the bundle, as sequentially shown by FIGS. 4a to 4e inclusive.
When the strap 6 has a portion overlapping the initial or free end thereof, the turn of the strap around the bundle 3 is attached by the crimping member 47, as shown in FIGS. 5 and 5a. This is done by pushing the overlapping portion against the turn around the bundle, crimping a metal clamp around the contacting strap portions and thereafter withdrawing the crimping member 47. Thereafter, the jaws 27 and 28 which had been holding fast the free end of the strap are opened fully, as shown in FIG. 9, such that they retract substantially fully to the inner side of the pivot 26. The jaws are then free to move transversely of the strap and close to the latter. The hydraulic cylinder 23 is then retracted, causing the carriage 22 and the cutting and clamping tool to move upwardly and forwardly transversely of the initial end of the strap, as shown in FIG. 7, until it aligns with strap outwardly of the metal clamp 48. The closing of the jaws at that point first causes the fingers 37 to pinchthe strap 6 and locate the latter in registry with the punch 39. Further closing of the jaws causes concerted cutting of the strap by the cutting edge of the plate 33 and clamping of the strap by the plates 29, 30, 32, 34, 35, and 36 and, in particular, by engagement of the punch 39 through the strap in an aperture 50 which is punched therethrough. The hydraulic cylinder 23 is thereafter expanded to rearwardly lower the cutting and clamping tool, as shown in FIG. 8, and thereby pull the initial or free end of the strap to the starting position to attach another bundle.
As is well known in the related art, the unrolling or dispensing of the strap from the spool 17 must preferably be regulated or made under tension to form a taut turn around the bundle.
It should be easily understood that the integrated cutting and clamping tool according to the principle of the present invention may be used per se or in combination in another machine using a strip or line and particularly a metal strap whereby concerted side-by-side cutting and clamping of the tying element, strip or line may be produced.
It should also be noted that the jaws need not necessarily be made of juxtaposed plates as aforedescribed as long as they include the cutting edge and the punch arranged side by side.
