The invention relates to packaging equipment, in particular to devices for packaging rod-shaped articles, for example spindles.

Apparatus for packaging rod-like objects, such as pencils, matches, cigarettes, rollers, etc., are known. bags or stacks. Such devices contain completed mechanisms for transporting, orienting, forming a package or stack, feeding it into a package or container.

A device is known for packing rod-shaped objects, having their complex outer surface, in which drives are used, having vertical movement from pneumo-hydraulic actuator 1.

However, this device is difficult because it is difficult to adjust the pitch of the drive. To move the drive horizontally, you need to use an additional drive. To speed up the drive to its initial position, it is necessary to have a speed switch, which complicates its operation.

It is also known a device for stacking rod-like objects, containing a lifting-lowering table for objects, an object feeding mechanism and a container lifting mechanism having a slide with a leash 2.

The drawbacks of the device are: the lack of adjustment for lowering the table in height; unloading is done in the same direction as loading; it is impossible to carry out the pushing of products, which greatly complicates the operation and reduces the capabilities of the device; it is difficult to move products from the table on the table, since it is necessary to roll them over the already lying row of products, which leads to damage; there is no horizontal movement of the stacking table in rows.

The purpose of the invention is to improve the performance of the device and prevent damage to objects.

The goal is achieved by the fact that, in a device for placing rod-like objects in a container, containing a lifting table for objects, an object feeding mechanism and a container lifting mechanism having a slide with a leash, the table is mounted on a rack with teeth located on two opposite sides, under the rail a movable cam is mounted, on which two parallelogram mechanisms are attached with a rail dog and a support in contact with the cam, while the rack rail has a cable-block system with a movable block on which a stop is mounted associated with the carrier of the container lifting mechanism.

In addition, dogs can have an adjustable spring-loaded lever, supports can be installed with

displacement along the pa r of the parallelogram mechanism, and the rack bar can be rotated and have additional rows of teeth.

However, a lever with a roller can be mounted on the slider to fix

tara.

Pins can be fixed on the device case, and holes are made on the table.

FIG. 1 schematically shows a device for placing rod-shaped objects in a container; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 - the position of the pawl, parallelogram and spring lever at the time of bypassing the tooth of the slats with which the dog came into contact; in fig. 5 - the position of the pawl, parallelogram and spring-loaded lever at the time of entry of the pawl into engagement with the next tooth of the slats.

A device for stacking rod-like objects consists of a table 1 (Fig. 1) with a set of zaschaty rails 2 mounted on wheels 3 with shoulders in guides 4 which are fixed to the base 5. A set of racks 2 serves to change the amount of lowering (lifting) table 1 for one move. The pitch of the rails is changed by rotating the rail around the axis 6 and bringing the teeth of the corresponding schag in contact with the pawls 7 (Fig. 1 and Fig. 2). The pawls 7 are alternately in contact with the rail 2 installed. Each paw 7 is fixed on the axis 8 of the head 9 of the parallelogram 10 fixed on the base 5. The trunks 11 of the parallelogram 10 have grooves in which the supports 12 are mounted with rollers in contact with the copier 13, which is a bar with a shaped groove made in the form of symmetrically arranged upper and lower ledges for each support 12. The ability to move the supports 12 in the grooves of the grating 11 allows you to change the value of the vertical stroke of the pawl 7 depending on the teeth of the teeth installed th on the rail 2. The pawl 7 is made so that the side (with respect to axis 8) contacting with the toothed -reykoy 2, p idle state always rotated upward (opposite side substantially heavier). To return the pawl 7 to the horizontal position, a lever 14 with a spring 15 is installed (Fig. 4 and Fig. 5), and the angle of rotation of the lever 14 around its axis, and consequently, its accompanying path of the pawl 7 (when lowering the table 1 is less than a tooth pitch, when lifting, it is more than the spike of the tooth) is regulated by the stop 16, which can move along the groove 17 at the base 5. The amount of support of the pawl 7 by the lever 14 depends on the pitch of the lath 2. If the lever 14 constantly contacts the pawl 7, when the copier 13 moves, the table will begin rise up, i.e. This design can be used both for lowering products and lifting them. Copier 13 moves in rollers 18 from pneumatic cylinder 19 through lever 20, shaft 21 and fork 22 connected to copier 13 by pin 23. Copier 13 has adjustable stops 24 for movement at the end of the movement of base 5 along rails 25 fixed in racks 26 This is necessary in order for the feeding mechanism 27 (even or odd) of the feed 28 (of the type "shaft") to be placed in the spaces of the row 1 of the products 28 already on the table. The amount of lateral movement of the base 5 and table 1 is adjusted and equal to half the diameter of the product 28. Step launching the table 1 also depends on the diameter of the stacked products 28. A pusher 30 is installed with a pneumatic cylinder 31 for placing the formed stack of products 28 into the container 29 (box). At the same time, to unload the wheels 3 from the lateral force that occurs when the foot is pushed into the container, The base 5 is mounted with plugs 32, and on the table 1 there are corresponding openings. The container 29 is fixed to the frame 33 of the lifting mechanism mounted on the sliders 34 (Fig. 1 and Fig. 3) and associated with the pneumatic cylinder 35. The frame 33 is held in a vertical position not only by the pneumatic cylinder 35, but also by the latch 36 with the spring 37. The latch 36 - at one end has a bevel for setting the frame 33, and at the other - an emphasis for contact with the diaphragm chamber 38, designed to compress the spring 37 and retract the latch 36, from the frame 33. Each slider 34 moves from its guide 39 and is equipped with a lever 40 with roller 41. The lever 40 is mounted on the axis 42 and serves to lock the slider 34 is in the upper position, because the roller 41 under the action of the gap 43 of the frame 33 on the lever 40 comes to the end of the guide 39. This design provides a strict sequence of movement of the frame 33 and sliders 34 when the pneumatic cylinder 35 moves, and also fixing the frame 33 with the container 29 in the upper position in emergency situations when there is no pressure in the pneumatic circuit. As the pneumatic cylinder moves downward, the frame 33 first rotates around the axis 44 and only after the eyelet 43, turning 90 °, releases the lever 40 and the roller 41 comes off the end of the guide 39, the slider 34 together with the frame 33 will start to go down. During the return stroke of the pneumatic cylinder rod 35, the frame 33 rises, being in a horizontal position, as the roller 41, which is in contact on the side surface of the guide 39, does not allow the pro-nose 43 (having a bevel for approach and deflection of the lever 40) to rotate by 90 ° and only then, the slider 34 will reach the extreme upper position, the frame 33 can rotate around the axis 44, the lever 40 deflecting the roller 41 on the opening 43 by locking the roller 41 on the end of the guide 39. On one of the sliders 34 there is a bracket 45 on which the leash 46 is fixed on axis 47. Part of the leash 46, lying On the strip 48, more desirable (relative to the axis 47) than that which is in contact with the strip 49. The lead 46 periodically contacts the stop 50 attached to the mobile unit 51 by means of the axis 52. The mobile unit 51 is mounted on the guide 53 and connected by means of a cable 54 and blocks 55 to a set of teeth: white rails 2 of the table 1. Such a KOHCTpyx ji allows accelerated lifting of the carriage 1 while lowering the frame 33 (raising the table 1 can also be done by putting the lever 14 into constant contact with the pawl 7 and turning on the pneumatic cylinder 19 on a continuous return-post sweeping movement). The lifting of table 1 with the help of the leash 46 and the stop 50 will occur until the lead 46 leaves the strip 49, after which it turns on the axis 47, bypasses the stop 50 and again takes a horizontal position on the strip 48. (Not shown in the drawings limit switches defining the cycle of operation and the position of the mechanisms). The device for placing in a container rod of various items works as follows. A table 28 is placed on the table 1 using a manipulator 27, after which a signal is given to trigger the pneumatic cylinder 19. The pneumatic cylinder 19 through the lever 20, the shaft 21 and the fork 22 begins to move the copier 13. The support 12 of the parallelogram 10 located on the lower horizontal of the groove of the copier 13, rolling on the lower step of the copier 13, lifts the pawl 7, which bypasses the contact in contact with it in the previous cycle of the rack 2. Then, when the support 12, already on the horizontal platform of the lower step of the copier. 13 will continue to rise along the upper ledge, the support 12 of the parallelogram 10 with the pawl 7 meshed with the rail 2 will begin to descend (previously, this support 12 moved along the upper horizontal part of the copier groove 13 and the table 1 did not descend). But the pawl 7 is in contact with the lever 14 and, as it rises, rotates on the axis 8 to a horizontal position, the entrance to the trough of the next tooth of the slats 2. As soon as the elevator from the support 12 reaches the upper horizontal part of the groove of the copier 13, it will engage the dog pitch tooth of the rail 2, since at this time the support 12 of the lowering pawl 7 moves to the horizontal platform of the lower step of the copier 13, the transfer of the carriage from one pawl to the other takes place. Next, the pawl 7, lowering, the support 12 along the lower step of the copier 13 moves away from the tooth of the slats 2 and rotates around the axis 8 until it takes such an inclined position that its end will leave the zone of the rack 2. At the end of its turn the copier 13 stops 24 with the base 5 and under the action of the pneumatic cylinder 19 moves it together with the table 1 and the products 28 along the guides 25 to the left against the stop with the pillar 26. At this stage, the table 1 is lowered by one step and its horizontal movement ends. When laying the manipulator 27 of the next row of products 28 on the table 1, the signal for switching on the pneumatic cylinder 19 is again given, the rod moves back, the copier 13 returns to its original position. Dogs 7 are swapped. those. the lower one moves up and comes into contact with the next tooth of the lath 2, and the upper one goes, downwards and gets out of engagement with the lath 2. Table 1 with guides 4 and base 5 return to their original position, i.e. move to the right as shown in the drawing. This will continue until a complete stack of articles 28 has been reached. After the manipulator 27 has laid the last row of products 28, table 1 is lowered onto base 5. Pins 22 enter the corresponding holes on table 1 and fix it. A signal is given at the beginning of the movement of the pneumatic cylinder 31, after which the pusher 30, moving, pushes the products 28 from the table 1, putting them into the container 29. On returning the pusher 30 to the initial position, the pneumatic cylinder 35 is lowered, and the diaphragm chamber 38 opens the latch 36 The frame 33 with the filled container 29 first rotates into a horizontal position around the axis 44 then, as soon as the lugs 43 come out (turning 90 °) from contact with the levers 40 and allow the rollers 41 to go off the ends of the guides 39, the frame on the sliders 34 begins go down down on the detachment area of the container 29. When the sliders 34 are interleaved, the leash 46 attached to one of them contacts the stop 50 of the movable block 51, which is in its highest position, and lowers it down, thereby raising the table 1 to its original position for dialing new foot products. During the next set of articles 28 on the table 1, the container 29 with the finished product is disconnected from the frame 33 and a new one is installed. By pressing the manual control button, the diaphragm chamber 38 is turned off and the pneumatic cylinder 35 is turned on to rise. The frame 33 with the empty container 29 first rises, being in a horizontal position, since the rollers 41, abutting against the guide 39, do not allow the lugs 43 to deflect the levers 40 and rotate 90 °. When the sliders 34 take the uppermost position, and the rollers 41 come out of contact with the side surface of the guides 39, the frame 33 under the action of the pneumatic cylinder 35 will begin to turn on the axis 44, the lugs 43, the deflection levers 40, lock the rollers 41 on the end of the guides 39, the The most locking position of the sliders 34. Turning on, the frame 33 enters the latch 36 and stops. With this, the job of forming the foot and placing it in the container ends. The filled container is transported to the warehouse and further to the consumer. The use of a device for stacking rod-like objects in conjunction with a manipulator with a step-by-step conveyor for the formation of even and odd rows will allow you to fully automate the process.

unloading and oriented packing of spindles into taras; we manufacture them with Tognos.

In the proposed device, a single return container is provided in which the spindle is stacked vertically in one row at the machine and then transported to the customer. For vertical transport

spindles there is no need for paper pads between rows. The absence of overlaps, the influence of the weight of the top products during transportation helps to preserve the quality of the spindles, and the productivity is increased by self-quotation to the initial position of the table when lowering the filled containers.
