Definitions
- the invention relates to a device for tearing open and / or opening sacks, according to the preamble of claim 1.
- the object of the invention is to improve the device in such a way that to prevent long materials that are difficult to tear into the gaps between the Conveying elements come to a standstill and by winding the tearing device can bring.
- At least one of the adjacent conveying elements several the other conveying element transverse to Direction of movement at least partially covering and / or Scraper elements are arranged.
- these covering and stripping elements By means of these covering and stripping elements the gap between the adjacent conveyor elements covered so far that preventing items that are difficult to tear for a long time, such as, for example Sisal threads and videotapes run through the gap into the interior of the Can pull tear device.
- These objects then lie on the Cover and scraper elements and can not be pulled into the interior become. Due to the front scraper edge, the areas of the Conveying elements in the adjacent area kept clean from each other, so that material is prevented from getting inside. Rather, the material is through the cover and wiper element is pushed out of the critical area.
- a particularly good stripping and cleaning effect is achieved in that the Cover and / or stripping elements are arranged spaced apart.
- the cover and / or stripping elements not as circumferential rings, but by the spaced apart elements as an interrupted ring, saw-like element is formed, only with the blockage-free work the accompanying self-cleaning.
- a circumferential ring has in many cases not the desired effect, but constipation occurs more often, such as Have shown attempts.
- Only the sawtooth-like design and arrangement of the Scraper and / or cover elements brings the in a completely surprising way Breakthrough for the creation of a non-clogging device.
- the distances between the cover and / or stripping elements can be larger and / or are less than their length in the direction of movement of the funding elements.
- a particularly good wiping effect is achieved in that the covering and / or Scraper elements are bevelled on their front side transversely to the direction of movement in such a way that its front side is based on the attachment side their direction of movement obliquely or obliquely curved and / or slightly arched runs backwards.
- the slopes can be straight and / or curved or slightly arched.
- the covering and / or Scraper elements seen in the direction of movement, curved in cross-section and / or are gabled.
- the device for tearing bags has the frame 1, which is on the side suitable wall parts 2 is clad.
- the shaft 3 is arranged on the frame 1.
- the ripping drum 4, which is designed as a drum-like element, is on this shaft 3 arranged.
- the tear drum 4 consists of the two as conveyor elements trained strip drums 5 and 6, with the strips 7 and 8 of the Strip drums 5 and 6, the tear elements 9 are arranged.
- the two Strip drums 5 and 6 are rotatably mounted on the shaft 3. Every strip drum 5 and 6 consists of the circumferential cylindrical strips 7 and 8, respectively, on a Support frame 10 or 11 are screwed tight.
- the supporting structure 10 of the first Strip drum 5 consists of struts 12 and those parallel to shaft 3 extending support rails 12 '.
- the struts are rotatable on the bearing 13 Shaft 3 arranged.
- the second strip drum 6 consists of those on the supporting structure 14 attached strips 8.
- the supporting structure consists of the struts 15 and the Support rails 15 '.
- the struts 15 are also rotatable with the bearing 16 on the shaft 3 stored.
- On the outer strut 12 of the first strip drum 5 is a Drive gear 17 attached, which with a drive gear 18 of a first Hydraulic motor 19 is non-positively connected via a drive chain 20.
- the outer Strut 15 of the second strip drum 6 is non-positively connected to the drive wheel 21 connected, which also via a chain connection 22 with a second hydraulic motor 23 is non-positively connected.
- the Covering and stripping elements 25 are on their front side 26 transversely Direction of movement 27 bevelled, in such a way that the front 26 thereof its fastening side 28, based on its direction of movement 27, obliquely runs behind.
- the covering and stripping elements 25 are transverse beveled to the direction of movement and in such a way that the back 29 of their Fastening side 28 runs obliquely forward.
- the covering and stripping elements 25 are seen in the direction of movement 28, slightly curved in cross-section and / or designed like a gable roof.
- the counter-holding elements 30 are arranged on the frame 1, which consist of there are mutually movable strips.
- the strips of the counter holding elements 30 are in the exemplary embodiment by means of a joint arrangement 31 on the frame 1 pivotably arranged and are by means of hydraulic cylinders 32 or others resilient elements pressed in the direction of the tear drum 4. It is also possible, these movable strips of the counter-holding elements 30 by means of a leaf spring or to produce from resilient material itself and to arrange it resiliently on the frame 1. In in some cases, only the result of the weight of the strips is sufficient Counterforce.
- the strips of the counter-holding elements 30 are attached to them by means of the joint arrangement 31 seen in the direction of rotation 27 of the strip drum 5 and 6 rear end on the frame 1 articulated.
- the front end is designed as a free end.
- the stripes of the Counter-holding elements 30 are shaped like an elephant's trunk.
- the tear drum 4 and the counter-holding elements 30 are arranged such that between the tear drum 4 and the counter-holding elements 30 an upward opening funnel 33 results in the bags 34 to be torn open.
- the strip drums 5 and 6 are about 160 ° to twist to each other. This is due to the design of the support structures 10 and 11 attributed, which are nested within each other.
- the tear-open drum 4 is driven in the direction of the arrow 27. Only one of the strip drums 5 and 6 rotates over the respective rotation phases, while the other strip drum 5 and 6 is stationary.
- the strip drums 5 and 6 are gradually rotated alternately by approximately 180 °, the first and last phase of the rotating phase overlapping by approximately 20 °.
- the drive motors 19 and 23 are then driven such that the first drive motor 19 stands still in the first phase, that is to say that the first strip drum 5 does not move either.
- the second drive motor 23 rotates the second strip drum 6 by 160 °.
- the first drive motor 19 is switched on over a phase of approximately 20 °, which means that both strip drums 5 and 6 of the ripping drum 4 rotate over a rotary phase of approximately 20 °. This is advantageous because large braking and starting torques are avoided by using the energy when braking one drum 5 or 6 to cause the other drum 5 or 6 to start.
- the second drive motor 23 is switched off and the first strip drum 5 is rotated by the first drive motor 19 by approximately 160 °, the second drive motor 23 then again is switched on over a rotation phase of approximately 20 °.
- the first drive motor 19 is then switched off, and the second drive motor 23 drives the second strip drum further by 160 °.
- This phase change takes place continuously, so that the strip drums 5 and 6 in one stop-and-go operation ".
- stop-and-go operation "of the nested strip drums 5 and 6 a relative movement between the tear elements 9 of adjacent strips 7 and 8 of the tear drums 5 and 6 is achieved, so that the bags 34 can be torn open safely and emptied. Furthermore, is avoided that there are windings or other blockages of the ripping drum 4.
- the oblique front 26 and the oblique rear 29 of the cover and Stripping elements 25 each form strippers for strips 5 and 6 in their neighboring area and thus ensure reliable operation of the Tear-open drum 4. Through the selected slope of the front 26 and the rear 29 the material to be stripped in the direction of arrow 35 away from the gap 24 pushed.
