Description

[Detailed description of the invention] [Field of industrial application] This invention relates to an improvement of a crusher for compressing empty cans, empty bottles, etc., using a chain with a caterpillar.

[Conventional technology]

The inventor proposed compression crushing, in which a pair of chains with caterpillars are arranged in a V-shape within the machine frame, and objects to be crushed, such as empty cans and bottles, are put into the V-shaped space between them and crushed. An application has been filed for the machine (see Japanese Patent Application Laid-open No. 143840/1983). However, in this invention, the chain with caterpillar is fixed,
It was not possible to change the distance between the chains with both caterpillars.

In addition, one chain with a caterpillar is provided so as to be movable back and forth, so that the distance between both chains with a caterpillar can be changed, and one of the chains with a caterpillar is configured to be suspended from the shaft of its upper sprocket. A device that can be rotated back and forth is known (see Japanese Utility Model Publication No. 53-5261).
This compression crusher can remove objects to be crushed or foreign objects that are clogged or caught between both chains with caterpillars without stopping operation.

[Problem that the invention attempts to solve]

However, the latter compression crusher described above is configured with a chain with a caterpillar that rotatably holds a plurality of sprockets between two side plates, and the shaft of the upper sprocket of the chain with a caterpillar passes through the machine frame. As a result, the structure of the chain with a caterpillar itself and its mounting structure have become complicated.

In addition, since the chain with a caterpillar for compressing and crushing work and the mechanism that drives it are both installed within the machine frame, there is a risk that compressed and crushed cans, bottles, etc. may hit the drive mechanism and cause damage to the drive mechanism. Ta.

Furthermore, since a transmission mechanism using gears is used as a drive mechanism for the chain with a caterpillar, the drive mechanism is complicated.

This idea was made in order to solve the problems of the conventional compression crusher mentioned above, and in a compression crusher in which the distance between a pair of chains with caterpillars can be changed, the structure of the chain part with caterpillars and its To provide a compression crusher having a simple mounting structure and a simple drive mechanism for a chain with a caterpillar, and in which there is no possibility that compressed and crushed materials will damage the drive mechanism of the chain with a caterpillar.

[Means for solving problems]

In order to achieve the above objective, this invention takes the following technical measures.

That is, a pair of chains with caterpillars are provided in a part of the machine frame having a width that is almost the same as the width of the chain, and the lower shaft of the chain with caterpillars whose lower end is movable is the upper shaft of the chain with caterpillars formed on the machine frame. The shaft is inserted into an arc-shaped notch with a center at the center of the shaft, and is supported movably along the notch, and an operating handle and a support are attached to the shaft on both sides of the exterior of the machine frame, and the support is attached to the shaft. , the lower shaft is configured to be removably locked to a locking portion provided on the machine frame to position the lower shaft at a compressing and crushing position, and the pair of chains with caterpillars are driven by the machine. The chain belt is connected to the outside of the frame via a chain belt, and the chain belt is engaged with the drive sprocket of one chain with a caterpillar on its inner circumferential surface and with the drive sprocket of the other chain with a caterpillar on its outer circumferential surface. This is a characteristic feature.

[Effect]

With the structure described above, if the chain with caterpillar is placed between the sprockets and bearings provided on the lower shaft, which is movable along the notch formed in the machine frame, and the upper shaft, which is fixed, the chain can be fixed at a certain level. It can be held in tension and will not loosen even when its lower shaft is moved.

In addition, since both sides of the pair of chains with caterpillars are almost completely covered by the machine frame, the material to be crushed does not scatter outside from the V-shaped space between them.
On the other hand, since the drive mechanism is provided outside the machine frame, there is no risk that the material to be crushed will hit the drive mechanism and cause damage.

〔Example〕

Hereinafter, embodiments of this invention will be described based on the accompanying drawings.

Figures 1 and 2 are general views of the compression crusher according to this invention, in which 1 is an outer cover, 2 is a machine frame, 3 is a charging duct, and 4 is a temporary container for compressed and crushed empty cans, empty bottles, etc. This is a storage box to store the objects. An input port 5 is provided at the upper front surface of the outer cover 1, and an ejection port 6 for entering and exiting the storage box 4 is provided at the lower front surface.

Inside the machine frame 2, endless chains 7 and 8 with caterpillars are arranged opposite each other in a substantially V-shape, and a geared motor 9 for driving these chains is attached in front of the chain 7 with caterpillars.

This part of the machine frame 2 in which the chains 7 and 8 with caterpillars are provided is closed at the front, rear and left and right sides, and is open only at the top and bottom. The geared motor 9 is provided outside the relevant portion of the machine frame 2.

As shown in FIG. 4, the front chain 7 with a caterpillar is suspended on a bearing 11 attached to an upper shaft 10 and a sprocket 13 fixed to a lower shaft 12. , 14 by machine frame 2
is rotatably attached to. Also, machine frame 2
On the outside, a drive sprocket 15 is fixed to the lower shaft 12, and further includes a pair of operating handles 16, 16 and a pair of support rods 17, 1.
7 are rotatably attached by bearings 18 and 19, respectively. Support rod 17, 17
The tip of the locking rod 20, 20 fixed to the machine frame 2
is attached to the side of the

Arc-shaped notches 21, 21 are formed on both sides of the machine frame 2, with the upper shaft 10 at the center, and the bearings 14, 14 fit into each notch 21, 21.
It is designed to slide inside.

As shown in FIG. 5, the rear caterpillar chain 8 spans a bearing 23 attached to an upper shaft 22 and a sprocket 25 fixed to a lower shaft 24, and the lower shaft 24 is connected to a bearing 26, Machine frame 2 by 26
is rotatably attached to. Further, a drive sprocket 27 is fixed to the lower shaft 24 on the outside of the machine frame 2. This drive sprocket 27 and the sprocket 2 of the geared motor 9
A chain belt 29 is stretched across the drive sprocket 8, and the outer peripheral surface of the chain belt 29 meshes with the drive sprocket 15.

Next, the usage conditions of the compressor crusher according to the invention having the above structure will be explained.

When the geared motor 9 is turned on, the rotation of the sprocket 28 is transmitted to the drive sprockets 15 and 27 by the chain belt 29,
Both lower shafts 12, 24 rotate in opposite directions. Along with this, both chains 7 and 8 with caterpillars, which are opposed to each other in a substantially V-shape, rotate in the direction of the arrow in the figure.

Therefore, when objects to be crushed such as empty cans and empty bottles are inputted from the input port 5, they enter the V-shaped space 30 between the two chains 7 and 8 with caterpillars through the input duct 3, and are compressed by the caterpillars. After being crushed, it falls into the storage box 4.

If the V-shaped space 30 is clogged with foreign matter and compression crushing becomes impossible, open the back cover 31 and remove the support rod 1.
When 7 and 17 are rotated upward to release the lock from the locking rod 20, the lower shaft 12 is moved to the notch 21,
It becomes possible to move forward along 21. When the operating handles 16, 16 are moved forward, the distance between the lower shafts 12, 24 becomes wider, and foreign objects easily fall and enter the storage box 4.

After the foreign matter has been removed, by moving the lower shaft 12 backward, the branch retainers 17, 17 will automatically rotate downward and the locking portions 17a at their tips will engage the locking rods 20, 20. is locked. In this way, the lower shaft 12 is fixed and is in its normal operating state thereafter.

Support rods 17, 17 and operating handles 16, 16
is rotatably attached to the lower shaft 12, so there is no need to stop the chain with caterpillar 7 even while the lower shaft 12 is moving, and the lower shaft 12 rotates around the upper shaft 10. Therefore, the chain 7 with caterpillar does not loosen.

Further, the rotation of the geared motor 9 is controlled by a single chain belt 29 between both drive sprockets 1.
5 and 27 at the same time, there is no need for gears, chain belts, etc. for rotating the chains 7 and 8 with caterpillars in opposite directions, and the structure of the drive part becomes simple.

[Effect of idea]

This invention has the above-mentioned configuration and has the following excellent effects.

The chain 7 with a caterpillar whose lower end is movable can exert a certain tension simply by fixing its upper shaft 10 to the machine frame 2 and movably supporting the lower shaft 12 in a notch 21 formed in the machine frame 2. Since the chain 7 can be mounted without changing its tension even if it is moved, there is no need for any other parts to keep the tension of the chain 7 with a caterpillar constant or to guide it. Therefore, the configuration of the chain portion with caterpillar and its mounting structure can be made very simple.

Compression and crushing work is performed within the machine frame 2, and drive mechanisms for the chains 7 and 8 with caterpillars, such as the drive sprockets 15 and 27, the chain belt 29, and the geared motor 9, are provided outside the machine frame 2. The object to be crushed, such as compressed and crushed cans, does not hit the drive mechanism, and therefore, the risk of damage to the drive mechanism can be completely eliminated.

Since it is possible to drive the chains 7 and 8 with both caterpillars with one chain belt 29 in the opposite direction of rotation, the configuration of the drive mechanism can be extremely simplified, and moreover, when gears are used, It can be manufactured at a lower cost with lower noise and vibration compared to the previous one.

Even when the drive sprocket 15 is attached to the lower shaft 12 of the movable chain 7 with tracked pillars, the positions of the components can be set so that the tension of the chain 7 with tracked pillars does not change due to the movement of the lower shaft 12. Additionally, this increases the range in which the layout of each component can be changed.

Since the lower shaft 12 of the movable chain 7 with caterpillars is supported by the machine frame 2 at the arc-shaped notch 21, the weight of the chain 7 with caterpillars does not directly act on the upper shaft 10, resulting in excellent durability. There is.

Since the supports such as the support rod 17 and the locking portions such as the locking rod 20 are provided outside the machine frame 2, it is easy to check whether or not the supports are locked and the locked state.
