Description

one

The invention relates to equipment for packing boxed items, preferably rectangular with a top cover, and can be used in the food, chemical and other sectors of the national economy.

The closest to the invention to the technical essence and the achieved result is a device for placing piece goods in boxes, containing a mechanism for opening boxes, a mechanism for feeding products into boxes, a mechanism for closing boxes, and a conveyor with pushers for emptying and withdrawing filled boxes (one).

A disadvantage of the known device is that, in connection with the application of vacuum suction cups for performing these operations, it has a complex system for supplying and distributing vacuum and complex kinematics. In addition, when the box is closed, the lid is lowered by a vacuum suction simultaneously with the entire plane, which requires great accuracy in the relative orientation of the case and the lid due to the need to combine them simultaneously around the entire perimeter of the coupling. With

a small error in the relative position of the case and the cover, and when the walls of the walls are deformed, the device may fail.

The purpose of the invention is to simplify the design and increase reliability.

This goal is achieved by the fact that in Q the proposed device is a mechanism. for opening the boxes consists of a lifting and lowering table with a clip for the box, spring-loaded latches located above the table, and a transverse pusher, and a mechanism for

The box closing 5 consists of a pivotally reinforced driver with a spring-loaded dog and roller, a copier and an intermediate bridge, the surface of which is curved according to the profile of the copier, and the device has tables on tables to move the lids and boxes at different levels.

In addition, the mechanism for closing the boxes had latches made in the form of swiveling wedge-shaped canopies, the upper surface of which corresponds to the level of the upper edge of the housing.

FIG. 1 shows schematically a device for placing piece goods in boxes, a general view; in FIG. 2, section A-A in FIG. one; in fig. 3 section bb in fig. one; in fig. 4 mechanism for closing the boxes; in fig. 5 shows a section B-B in FIG. 3. The device (Fig. 1) comprises a conveyor 1 for supplying empty and withdrawing filled boxes, a mechanism for opening boxes, a mechanism 2 for supplying products to boxes, a mechanism for closing boxes, tables 3 and 4 with pushers 5 and 6, respectively, for moving the bodies and covers of the boxes located at different levels, and conveyors 7 for supplying products for installation.

Pushers 5 (fig. 2) for housings are rods mounted at the hinges of a chain that are located above the surface of table 3, and pushers of b for covers are attached to one of the chains of a plate with bent legs, while table 4 has a longitudinal slit (in the drawing not shown) for pushing paws b.

Conveyor 1 is equipped with drive and tension stations 8 and 9. Q The mechanism for opening the boxes (Fig. 3) consists of a lifting and lowering table 10 with a clip for the box, spring-loaded latches 11 for gripping the cover and a transverse pusher 12. The latches 11 are located above table 10, which is mounted on guides 13 mounted on frame 14. The clip for the box contains a rotary guide bar 15, the axis of which is parallel to the direction of movement of the conveyor, and a fixed guide bar 16. The spring 17 serves to turn the bar 15 in the direction of the boxes, and the lever 18 and the adjustable stop 19 - to turn it in the opposite direction.

The latches 11 for gripping the lid (fig. 4) are plates whose width is equal to the width of the lid mounted on the axes perpendicular to the direction of movement of the conveyor. At the lower edge of the plates there is a triangular protrusion, the horizontal platform of which is flush with the edge of the table 4 for moving the covers. The latches are interconnected by a spring 20, while the rotation of the latches under the action of the spring 20 is limited by the stops 21.

The pusher 12 of the covers is mounted on the supports 22 mounted on the frame 14 and can be brought into reciprocating motion with the help of the cam 23 through the system of levers 24.

To drive the table 10, a cam 25 and a system of levers 26 serve in reciprocating motion.

The mechanism for closing the Corbobox consists of a hinged (FIG. 5) reinforced leash 27c with a spring-loaded dog 28 and a roller 29, a copier 30 and an intermediate bridge 31, while the surface of the latter is curved according to the profile of the copier 30. The leash 27 is hingedly fixed at one end lever 32 connected to cam 33. For precise orientation of the lid relative to the box, there are transverse guides 34.

5 The mechanism for closing the boxes also has locks made in the form of pivotal 35 wedge-shaped peaks 36 on the swinging lever, the upper surface of which corresponds to the level of the upper edge.

housing, while the lever 35 is connected through a system of levers 37 with a cushion 38, which serves to inform him of a periodic movement.

5 The cams of all mechanisms are mounted on a common shaft located along the base of the device to ensure synchronization of all performed operations.

 The device works as follows.

Closed boxes are fed into the conveyor through a feeder (not shown in the drawing). Initially, the box is fed to the lifting and lowering table 10 of the mechanism for opening the boxes. (Fig. 3), while the cam 25 through the system of levers 26 raises the table 10, the lever 18 moves away from the stop 19 and under the action of the spring 17 the bar

0 15 rotates and presses the box body against the fixed bar 16, with the case being clamped at its lower part (below the edge of the lid).

5 When lifting the vessel 10 to the upper position, the lid is inserted between the latches 11, pushes them apart, overcoming the force of the spring 20, while the lower edge of the lid appears

Q above the horizontal area of the protrusions of the latches 11 (Fig. 4).

Claims (2)

When the table 10 moves downward, the body held by the clamp is lowered together with the table, and 5 remain on the protrusions of the latches 11. Then, under the action of the cam 23 (Fig. 3) and the system of levers 24, the pusher 12 moves the spout to the table 4. In the lowest position of the table 10 Q the lever 18 pushes against the stop 19 and, turning the bar 15, releases the box body. At the next step of the conveyor, the body and the heel are moved by the corresponding pushers on the tables to the next position, and the next closed box is given on the table 10. The mechanism 2 for supplying products to the box is carried out by sequentially placing the products into the box, after which the latter is transferred to the lid by the conveyor into the mechanism for closing the box (Fig. 2}. When the conveyor is stopped, the cam 33 acts on the lever 32 that moves the leash 27 in the transverse direction. The pawl 28, abutting against the side wall of the lid, moves along its bridge 31 to the building. At the same time, under the action of the cam 38 and the system of levers 37, the visors 36 move to the body and, affecting the end walls of the body, It is rotated in a predetermined position (.fig. 5), while the upper plane of the visor is set at the upper edge of the case. During movement to the case, the lid is additionally oriented relative to it with the help of guides 34 and as it moves further along the bridge, the rear edge of the lid descends along the curvilinear plane of the bridge under the action of the leash 27, which, in turn, is lowered under the influence of the copier 30, along whose profile the roller 29 fixed on the leash rolls around. one edge of the body and is pressed by the dog 28 to its side wall (FIG. 5), while the opposite edge of the lid is supported by the visors 36. Then the visors 36 move in the opposite direction and release the lid, and with further movement of the leash 27, the pawl 28 rotates, overcoming the spring resistance, and the roller 29 hits the lid, pressing it to body. Then the lead 27 returns to its original position and the conveyor issues a filled and closed box from the device. The proposed apparatus for placing piece goods in boxes is simple in design and reliable in operation. Claim 1.
